Leiter-3 is selected to replace 
WRAML-2 for the evaluation of the 
change in cognition for the following 
reasons:Lack of availability of 
WRAML-2 in Spanish, Leiter-3’s 
high scientific validity, non-verbal 
format to offer less biased assessment 
for subjects whose second language is 
English, easier and shorter 
administration and short test time 
reducing investigator burden, as well 
as increase probability of the

Study drug administration will 
be taken at approximately the 
same time each day.  On the 
days of PK sampling and the 
day before the subjects come to 
the clinic for PK sampling, 
study drug will be taken in the 
morning and doses recorded 2 
days prior to the clinic visit.
This will ensure lower variability

addition, no adjudication will be 
performed.  Local 
echocardiograms can be 
performed if deemed medically 
necessary by the investigator.

strategy
A single dose pharmacokinetic study 
in pediatric obese subjects (APD356-
A001-026) indicated that patients with 
body weight greater than or equal to 
60 kg can be administered a dose 
similar to that given to adults and 
adolescents.  Based on Centers for 
Disease Control and Prevention 
(CDC) growth chart data, almost all 
subjects over 9 years of age are likely 
to be at or over 60 kg body weight.  
Therefore, children age 9 to 11 years 
have been included in the current 
study.

Study Design
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in obese adolescents, 
ages 12 to 17 years.  Approximately 260 subjects will be randomized in a 1:1 ratio to Belviq XR 20 mg QD
(130 subjects) and placebo (130 subjects).  Subjects will be stratified by sex.  Subjects will receive Belviq XR
20 mg or matched placebo QD in a 1:1 ratio for up to 52 weeks. A recruitment plan will be developed to ensure 
at least 20% of younger subjects (12 to 13 years of age) are enrolled in the study.  Throughout the duration of 
the study, subjects will be encouraged to adhere to a lifestyle modification program that includes a 
standardized, age-appropriate diet and exercise counseling. (revised per Amendments 02 and 03)
The study will consist of 2 phases: Prerandomization and Randomization.  The Prerandomization Phase will 
last up to 30 days and consist of 1 visit during which subjects will be screened for eligibility.  The 
Randomization Phase consists of a Treatment Period and a Follow-Up Period.  The Treatment Period will last 
for a maximum of 52 weeks, with visits at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52.  The Follow-Up Period will 
extend from the End of Treatment (EOT) visit to the End of Study visit.
Subjects who screen fail can be re-screened only once.  All subjects will continue in the study until the 52-week 
evaluation is completed.  Subjects who discontinue treatment prematurely will be followed up until study 
completion.  All attempts will be made to capture height and weight in all subjects whether or not they are still 
on study drug at the end of the study.  (revised per Amendments 03 and 04)
Study sites will be selected to ensure adequate representation of adolescents of ethnic and racial minorities.  
(revised per Amendment 03)
Data Monitoring Committee (revised per Amendment 03)
A Data Monitoring Committee (DMC) will be established to monitor and conduct periodic safety review of 
unblinded data. DMC members will be chosen based on their expertise in evaluating these clinical events. A 
separate DMC charter will be established.
Number of Subjects
Approximately 500 subjects will be screened to provide 260 randomized subjects.  (revised per Amendment 02)
Inclusion Criteria
1.
Healthy male or female adolescents, age 12 to 17 years (inclusive) at Screening, with an initial BMI that is 
greater than or equal to the United States (US)-weighted mean of the 95th percentile based on age and sex
with a body weight greater than 60 kg.  Subjects with T2DM may have a pre-existing or new diagnosis of

T2DM.
Subjects with pre-existing T2DM should have prior documentation consistent with the diagnosis and/or be 
on active pharmacotherapy for T2DM.  
Subjects with a new diagnosis of T2DM (ie, diagnosed at Screening) should be based on the 2016 
American Diabetes Association (ADA) guidelines.  The diagnostic criteria are met if a subject has 
unequivocal hyperglycemia (random plasma glucose ≥200 mg/dL (11.1 mmol/L) with classic symptoms of 
hyperglycemia or hyperglycemic crisis) OR any of the following criteria are observed and confirmed:
◦
HbA1c ≥6.5% 
◦
fasting plasma glucose (FPG) ≥126 mg/dL (7.0 mmol/L) 
◦
2-hour plasma glucose ≥200 mg/dL (11.1 mmol/L) by an oral glucose tolerance test (OGTT)
All T2DM subjects must have an HbA1c <10% at Screening.  If subjects are being or need to be treated 
with antidiabetic agents, the T2DM treatment regimen must be stable for at least 3 months before 
randomization.  A single rescreen is allowed following stabilization.  Stable control refers to minimal dose 
changes to existing medications for glycemic control and no medications being initiated for glycemic 
control in the 3 months before Randomization.  Minimal changes are defined as a change without any 
change in dose frequency, no add-on or discontinuation of other antidiabetic agents, and the subject has not 
been hospitalized due to hypo- or hyperglycemic events. (revised per Amendment 03)
2.
Subjects and their families not planning to move away from the area for the duration of the study
3.
Able and willing to comply with all aspects of the study, including a standardized, reduced-calorie diet and 
an age-appropriate, increased physical activity program
4.
Considered in stable health in the opinion of the investigator
5.
Caregivers or guardians meet the following requirements:
a.
Able and willing to support and supervise study participation in the opinion of the investigator,
including consideration of any existing physical, medical, or mental condition that prevents 
compliance with the protocol
b.
Able and willing to personally comply with and execute all aspects of the study requirements for the 
caregivers or guardians
Exclusion Criteria
1.
Clinically significant new illness within 1 month before randomization that may affect the subject’s ability 
to fulfill the study requirements or significantly confound the assessments
2.

4.
Any of the following findings on Screening echocardiography:

Aortic regurgitation mild or greater

Mitral regurgitation moderate or greater

Mitral or aortic valve stenosis greater than mild (ie, aortic stenosis [AS]: jet >3.0 m/s, mean gradient

area [MVA] <1.5 cm2)

Systolic pulmonary artery pressure (SPAP) >40 mmHg (and/or tricuspid regurgitation (TR) jet 
velocity >2.9 m/s)
In cases where an actual SPAP value is not measurable due to lack of adequate TR jet, the pulmonary flow 
acceleration time measured at the right ventricular outflow tract (RVOTAT), will be used to assess 
eligibility. Subjects with a RVOTAT ≤100 msec will be excluded, suggesting an elevated mean SPAP; 
eligibility for the those subjects with RVOTAT between 100 and 120 msec will be determined based on 
combined assessment of the TR jet, septal motion and right ventricular size.


oral steroids (topical and inhaled steroids are acceptable)

stimulant medications (eg, Ritalin, Concerta, Biphetamine and Dexedrine)

benzodiazepines
The following concomitant medication guidelines/restrictions will apply:

Medications for the treatment of hypertension, dyslipidemia, or diabetes may be started, discontinued, or 
adjusted during the study according to local standards of care if, in the judgment of the investigator or the 
subject’s physician, such a change is medically indicated.

For diabetic subjects treated with sulfonylureas, insulin (note that subjects should not be enrolled as 
indicated in exclusion criteria), or other antidiabetic agents with hypoglycemic risk, the risk of 
hypoglycemic events may be higher if the subjects experience rapid and significant weight loss (more than 
10% weight reduction than at the previous visit).  It is recommended that the physician advise the subject 
to monitor their blood glucose more frequently and adjust their antidiabetic medications and diet 
accordingly. 

The antihyperglycemic medication dose would be considered for reduction in the event of 1 documented 
and otherwise unexplained hypoglycemic event (blood glucose concentration <65 mg/dL) or 2 
undocumented and otherwise unexplained suspected hypoglycemic events between any 2 scheduled visits. 
For subjects on more than 1 antihyperglycemic medication, it is recommended to reduce insulin first (if 
applicable), then the oral and/or other injectable antidiabetic agents.  If the previous criteria are met again 
following dose reduction, further dose reductions or cessation of 1 or more antihyperglycemic agents, are 
suggested.  See Section 9.5.4.2 for the definition and reporting of hypoglycemic events. 
To minimize the risk of cardiac valve toxicity, subjects must not initiate use of agents that have documented 
correlation with increased incidence of valvulopathy and/or pulumonary hypertension (eg, pergolide, 
ergotamine, methysergide, or cabergoline) during the study.  If any of the above agents are clinically warranted, 
and subjects initiate any of these agents, lorcaserin HCl should be discontinued but can be restarted on 
lorcaserin HCl after being off the medications above for 1 month.  Otherwise, the study medication should not 
be restarted, but the subject should continue all study visits.  (revised per Amendment 03)

The Full Analysis Set (FAS) is the group of all randomized subjects regardless of adherence to study drug.

Per-Protocol Analysis Set (PP) is the group of all randomized subjects who are 80% or greater compliant 
with study medication, completed the study, have no major protocol deviations, have no violations of 
inclusion or exclusion criteria, and have BMI data at baseline and Week 52.  The determination of subjects 
to be excluded from this population based on the above criteria and a list of major protocol violations will 
be included in the statistical analysis plan (SAP) and finalized before data base lock.

The PD Analysis Set is the group of subjects who had sufficient PD data to derive at least 1 PD parameter.

The PK Analysis Set is the group of all randomized subjects from whom at least 1 valid lorcaserin plasma 
concentration was obtained with associated documented dosing history.

The population PK/PD set is the group of randomized subjects with PK information and who have at least 
1 adequately documented measurement of BMI.
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, and the PP will be used as a 
supportive analysis.  Unless otherwise specified, a 2-sided α=0.05 significance level will be used in all efficacy 
analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from baseline to Week 52.  The change from baseline in 
BMI will be analyzed using analysis of covariance model (ANCOVA) with factors of treatment,  sex (male and 
female) as fixed effect, and the baseline age and BMI as covariates.  The missing values will be imputed using a 
pattern mixture model utilizing multiple imputation (MI) assuming the missing values are missing not at 
random (MNAR).  The missing values will be imputed at each visit using all available values including the 
retrieved measurement from the postdiscontinuation data.  The details of the analysis model and missing value 
imputation method will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis:  The same primary efficacy analyses described above will be repeated based on the PP.

Change from baseline in standardized BMI score (Z-score):  The same primary efficacy analyses described 
above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed and will be
described in the SAP.
Key Secondary Efficacy Analyses
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 5% BMI reduction at

Week 52. The secondary efficacy endpoint will be analyzed only if the test for the primary efficacy endpoint is 
statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be analyzed using a logistic 
regression model with factors of treatment, sex (male and female), and baseline BMI as a covariate using FAS.  
Subjects with any missing assessment at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be analyzed using 
mixed effect model repeated measurement analysis (MMRM) and categorical variables will be analyzed using
the Cochran Mantel Haenszel test, Chi-square test, or logistic regression as appropriate.  Additional analysis 
may be performed as needed using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male and female), and 
race (American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or other Pacific 
Islander, or White) and age.  Additional subgroups may be explored, if deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and sensitivity analyses.
Pharmacokinetic Analyses
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using nonlinear mixed 
effects modeling. The effect of covariates such as baseline characteristics or demographics on PK will be 
explored. Derived exposure parameters such as the maximum observed concentration and the area under the 
concentration-time curve from time 0 to 24 hours at steady-state will be calculated from the final PK model 
using individual posterior estimates of the PK parameters and from dosing history. The PK analysis set will be 
used for this analysis.
Pharmacodynamic Analyses
Change from baseline in BMI will be assessed as the PD endpoint.  The PD analysis set will be used for this 
analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of subjects achieving ≥5% and ≥10% BMI 
reduction, and change in waist circumference from baseline) will also be assessed as part of the PD analysis.  
The PK/PD analysis set will be used for this analysis.
Pharmacokinetic/Pharmacodynamic Analyses
Population PK/PD modeling will be used to explore the relationship between lorcaserin plasma exposure and 
response, including but not limited to change in BMI from baseline and the probability of achieving at least a 
5% and at least a 10% change in BMI from baseline to Week 52.  Additionally, exposure-safety relationships 
for select safety parameters may be explored graphically depending on the data at the end of study.  Any 
emergent relationship may be modeled as appropriate.  Any parameters based on the study data may be 
considered for exploratory assessment for its relationship to PK.
Pharmacogenomic/Pharmacogenetic Analyses
Not applicable
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments including the incidence 
of AEs (including changes from baseline in physical examination, neuromuscular sign assessment for serotonin 
syndrome, and signs and symptoms of priapism and hyperprolactinemia), out-of-normal-range laboratory safety 
test values, change from baseline in laboratory safety test values, ECGs, vital sign measurements, bone mineral 
density and content, total body fat mass and total body lean mass by DEXA, FDA-defined valvulopathy, and 
pulmonary hypertension assessed by echocardiograph will be summarized by treatment group using descriptive 
statistics or frequency count as appropriate.
No hypothesis testing will be performed for the safety assessment.  (Revised per Amendment 04)

Other Safety Analyses
In addition, cognition will be evaluated by the Leiter-3, depression will be evaluated by the PHQ-9, and suicidal 
ideation and behavior will be evaluated by the C-SSRS, and will also be summarized by treatment group using 
descriptive statistics or frequency count as appropriate. For echocardiographic assessments, the proportion of 
subjects who develop FDA-defined valvulopathy, the proportion of subjects who develop pulmonary 
hypertension [pulmonary hypertension is defined when the subject’s systolic pulmonary artery pressure 
(SPAP) ≥40 mmHg evaluated by echocardiograph], and change from baseline in SPAP will be summarized by 
treatment group at Week 28 and Week 52 using descriptive statistics or frequency count as appropriate. (revised 
per Amendment 01)
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the first dose of study drug.
Interim Analyses

Sample Size Rationale
The proposed sample size is based on the comparison of the primary efficacy endpoint, change in BMI from 
baseline to Week 52 between the Belviq XR 20-mg treatment group and placebo group.  Assuming a SD of 
2.2 kg/m2 and a 40% dropout rate, a sample size of 260 subjects in a 1:1 ratio (n=130 in the Belviq XR 20-mg 
treatment group; n=130 in the placebo group) will have at least 80% power to detect a treatment difference of 
1 kg/m2 in BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at least a 5% 
BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, this sample of 260 subjects 
(130 subjects for Belviq XR 20 mg and 130 subjects for placebo) will also have greater than 78% power to 
detect an absolute difference of 20% between the Belviq XR 20-mg group and the placebo group, using a 
2-sided Chi-Square test with α=0.05.
The assumption used in the sample size calculation is based on the 
2 pivotal lorcaserin studies APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

ETHICS
5.1
Institutional Review Boards/Independent Ethics Committees
The protocol, Informed Consent Form (ICF), and appropriate related documents must be 
reviewed and approved by an Institutional Review Board (IRB) or Independent Ethics 
Committee (IEC) constituted and functioning in accordance with International Conference on 
Harmonisation (ICH) Good Clinical Practice (ICH E6), Section 3, and any local regulations 
(eg, Federal Regulations, Title 21 Code of Federal Regulations [21 CFR] Part 56).  Any 
protocol amendment or revision to the ICF will be resubmitted to the IRB/IEC for review and 
approval, except for changes involving only logistical or administrative aspects of the study 
(eg, change in clinical research associate [CRA], change of telephone number[s]).  
Documentation of IRB/IEC compliance with the ICH E6 and any local regulations regarding 
constitution and review conduct will be provided to the sponsor.
A signed letter of study approval from the IRB/IEC chairman must be sent to the principal 
investigator (PI) with a copy to the sponsor before study start and the release of any study 
drug to the site by the sponsor or its designee (ICH E6, Section 4.4).  If the IRB/IEC decides 
to suspend or terminate the study, the investigator will immediately send the notice of study 
suspension or termination by the IRB/IEC to the sponsor.
Study progress is to be reported to IRB/IECs annually (or as required) by the investigator or 
sponsor, depending on local regulatory obligations.  If the investigator is required to report to 
the IRB/IEC, he/she will forward a copy to the sponsor at the time of each periodic report.  
The investigator(s) or the sponsor will submit, depending on local regulations, periodic 
reports and inform the IRB/IEC of any reportable adverse events (AEs) per ICH guidelines 
and local IRB/IEC standards of practice.  Upon completion of the study, the investigator will 
provide the IRB/IEC with a brief report of the outcome of the study, if required.
At the end of the study, the sponsor should notify the IRB/IEC and Competent Authority 
within 90 days.  The end of the study will be the date of the last study visit for the last subject 
in the study.  The sponsor should also provide the IRB/IEC with a summary of the study’s 
outcome.
In the case of early termination or a temporary halt of the study, the investigator should 
notify the IRB/IEC and Competent Authority within 15 calendar days, and a detailed written 
explanation of the reasons for the termination/halt should be given.

Ethical Conduct of the Study
This study will be conducted in accordance with standard operating procedures (SOPs) of the 
sponsor (or designee), which are designed to ensure adherence to GCP guidelines as required 
by the following:
•
Principles of the World Medical Association Declaration of Helsinki 2013
•
ICH E6 Guideline for GCP (CPMP/ICH/135/95) of the European Agency for the 
Evaluation of Medicinal Products, Committee for Proprietary Medicinal Products, 
International Conference on Harmonisation of Pharmaceuticals for Human Use
•
Title 21 of the United States Code of Federal Regulations (US 21 CFR) regarding clinical 
studies, including Part 50 and Part 56 concerning informed subject consent and IRB 
regulations and applicable sections of US 21 CFR Part 312
5.3
Subject Information and Informed Consent
As part of administering the informed consent document, the investigator must explain to 
each subject and guardian/legally authorized representative the nature of the study, its 
purpose, the procedures involved, the expected duration, the potential risks and benefits 
involved, any potential discomfort, potential alternative procedure(s) or course(s) of 
treatment available to the subject, and the extent of maintaining confidentiality of the 
subject’s records.  Each subject must be informed that participation in the study is voluntary, 
that he/she may withdraw from the study at any time, and that withdrawal of consent will not 
affect his/her subsequent medical treatment or relationship with the treating physician.
This informed consent should be given by means of a standard written statement, written in 
nontechnical language.  The subject or the subject’s legally acceptable representative should 
understand the statement before signing and dating it and will be given a copy of the signed 
document.  If a subject is unable to read or if a legally acceptable representative is unable to 
read, an impartial witness should be present during the entire informed consent discussion.  
After the ICF and any other written information to be provided to subjects is read and 
explained to the subject or the subject’s legally acceptable representative, and after the 
subject or the subject’s legally acceptable representative has orally consented to the subject’s 
participation in the study and, if capable of doing so, has signed and personally dated the 
ICF, the witness should sign and personally date the consent form.  The subject will be asked 
to sign an ICF before any study-specific procedures are performed.  No subject can enter the 
study before his/her informed consent has been obtained.  The adolescent participant will 
provide written assent and the caregiver/guardian will provide written informed consent.
An unsigned copy of an IRB/IEC-approved ICF must be prepared in accordance with 
ICH E6, Section 4, and all applicable local regulations (Federal Regulations, 
Title 21 CFR Part 50, for studies in the United States).  Each subject must sign an approved 
ICF before study participation.  The form must be signed and dated by the appropriate 
parties.  The original, signed ICF for each subject will be verified by the sponsor and kept on 
file according to local procedures at the site.

INTRODUCTION
7.1
Indication
Obesity has become a global epidemic, causing a serious public health concern.  In the 
United States, the prevalence of obesity in adolescents ages 12 and 19 years has almost 
doubled over the past 2 decades.  The rate increased from 10.5% between 1988 and 1994 to 
20.5% between 2011 and 2012 (CDC/NCHS, 2013).  Obesity in adolescents, defined in the 
United States as greater than or equal to the 95th percentile in gender- and age-specific body 
mass index (BMI), continues to grow at an alarming rate in the United States and globally.  
Based on data (Wang and Lobstein, 2006) using various criteria for the definition of obesity 
that included more than 30 countries in Europe, North America, Asia, and the West Pacific, 
prevalence of obesity in these countries has also increased significantly, at a rate comparable 
to that in the United States.
Adolescent obesity has many negative implications for both the health and well-being of the 
individual as well as for society.  These include increased susceptibility to a host of diseases, 
chronic health disorders, psychological disorders, and premature death (Flegal, et al., 2005; 
Rofey, et al., 2009).  Increases in the prevalence of overweight and obese adolescents may 
result in a decrease in life expectancy for the first time in 200 years (Peeters, et al., 2003).
As a result, there is a significant impact on the cost of healthcare.  It is estimated that medical 
costs due to overweight adolescents are approximately $14 billion per year in the United 
States (Trasande and Chatterjee, 2009).  Obesity-related medical costs in general are
expected to rise significantly because today’s obese adolescents are likely to become 
tomorrow’s obese adults (Whitaker, et al., 1997).
Current approaches to weight management in adults include lifestyle modification, 
pharmacotherapy, and invasive bariatric procedures.  Lifestyle modification involves a 
combination of diet, exercise, and behavioral change, and is the preferred and essential 
strategy for weight management in obese and overweight individuals, including adolescents.  
Although lifestyle modification can be very efficacious in some patients, adherence to the 
prescribed regimens is often poor.  As such, lifestyle modification alone is often not adequate 
and the weight loss is often transient.  On the other hand, bariatric surgery and various other 
invasive procedures are generally reserved for the severely obese population. 
Pharmacotherapy can play a significant role in weight management programs, and is often 
combined with lifestyle modification to enhance weight loss beyond that which is normally 
achieved with diet and exercise alone.  Current pharmacotherapies offer the potential to 
significantly augment weight loss when combined with diet and exercise, but are rarely used 
for adolescents.
The current standard of care for treatment of obesity in adolescent subjects ranges from
behavioral therapy including lifestyle intervention to the rare use of pharmacotherapy in 
adolescents over 12 years of age (McGovern, et al, 2008; Spear, et al, 2007).  Xenical®
(orlistat) is currently the only product available for weight control in obese adolescent 
patients 12 to 16 years of age.  However, it is associated with gastrointestinal side effects

(Xenical PI. 2015), and the treatment effect of Xenical is modest. In a study that included 
539 obese adolescents with BMI above the 97th percentile, Xenical demonstrated a 0.86 BMI 
reduction relative to placebo after 52 weeks of treatment (-0.55 BMI in the Xenical treatment 
group versus +0.31 BMI in the placebo group) (FDA, 2003; Chanoine, et al, 2005).
Obtaining maximum retention in the study is a major goal in order to minimize missing data.  
A number of strategies have been used in prior adolescent weight loss studies may be used in 
the present study to help retain participants.  These include a highly trained and competent 
site staff, ample waiting area, readily available parking (at no cost), access to mass transit, 
and reminder and follow-up calls.  In addition, sites may utilize fun and interactive group 
sessions with games and hands-on nutrition and physical activity demonstrations, random 
raffle drawings, social events, birthday and holiday cards, and newsletters to further 
encourage subject retention.  Furthermore, we may make home visits for primary efficacy 
assessments, as needed, to maximize data collection. 
By incorporating some of these 
retention strategies, we hope that we will maximize participant retention, which will help us 
cope with missing data.
7.1.1
APD356/Belviq (lorcaserin hydrochloride)
7.1.1.1
Mechanism of Action
Belviq is a selective serotonin 2c receptor agonist which was approved by the US Food and 
Drug Administration (FDA) on 27 Jun 2012 as an adjunct to a reduced-calorie diet and 
increased physical activity for chronic weight management in adult patients with a BMI of at 
least 30 kg/m2 (obese), or adult patients with a BMI greater than or equal to 27 kg/m2
(overweight) in the presence of at least 1 weight-related comorbid condition.
7.1.1.2
Clinical Experience with APD356/Belviq (lorcaserin hydrochloride)
The Phase 3 clinical evaluation of Belviq in studies of more than 7700 adult subjects, 
including 604 subjects with Type 2 Diabetes Mellitus (T2DM), demonstrated clinically 
meaningful efficacy and a safety profile that includes minimal and easily managed risks.  In
each of the individual studies and in the pooled efficacy analyses, the Belviq dose met the 
following prespecified endpoints:

A significantly greater proportion of adult subjects taking Belviq 10 mg twice per day 
(BID) (47%) lost at least 5% of baseline body weight at 52 weeks as compared to 
subjects taking placebo (23%).  A significantly greater proportion of subjects taking 
Belviq 10 mg BID (22.4%) lost at least 10% of baseline body weight at 1 year as 
compared to subjects taking placebo (8.7%). 

The mean weight loss at 1 year in adult subjects taking Belviq 10 mg BID (-5.8 kg) was 
significantly greater than that in subjects taking placebo (-2.5 kg).
An integrated evaluation of the data from the pediatric, adolescent, and adult subjects 
revealed that the relationship between lorcaserin area under the curve (AUC) and body 
weight in pediatric and adult subjects is consistent irrespective of the individual studies or 
age range of the study population. Irrespective of age, lorcaserin AUC values in the pediatric 
subjects with body weight of greater than 60 kg overlapped with the data observed from the

studies involving adult subjects, suggesting a fixed dose approach similar to adults can be 
used for adolescent subjects with body weight greater than 60 kg.
In adolescent obese populations, it is anticipated that Belviq XR will result in similar effects.
As part of FDA postmarketing requirements, this study is designed to characterize the 
efficacy and safety of Belviq XR in adolescent obese populations in the United States.  It is 
also intended to support an indication for chronic weight management for obese adolescents 
ages 12 to 17 years old. 
7.1.2
Study Rationale
There is no specific FDA guidance for the approval of a weight loss product for adolescents.  
In adults, the Division’s 2007 draft Guidance for Industry Developing Products for Weight 
Management indicate that the product needs to satisfy either of the following mean or 
categorical criteria after 1 year of treatment:

The difference in mean weight loss between the active-product and placebo-treated 
groups is at least 5% and the difference is statistically significant.

The proportion of subjects who lose at least 5% of baseline body weight in the 
active-product group is at least 35%, is approximately double the proportion of subjects 
in the placebo-treated group who lose at least 5% of baseline body weight, and the 
difference between groups is statistically significant.
FDA awarded a weight management indication for Belviq based on Phase 3 study results 
which achieved the categorical criteria. In a Phase 3 study, a significantly greater proportion 
of subjects taking Belviq (47%) lost at least 5% of baseline body weight at 1 year as 
compared to subjects taking a placebo (23%).  It is anticipated that a similar effect will be 
demonstrated in obese adolescents, where weight loss will be assessed using BMI
measurements to account for growth. In this study, the objective is to demonstrate that BMI
reduction will be achieved during 52 weeks of treatment with Belviq XR 20 mg administered 
once daily (QD) compared to placebo in obese adolescents.
In the Phase 3 orlistat study in obese adolescents mentioned above, the proportion of subjects 
who lost at least 5% body weight is relatively low. At the end of the study at Week 52, only 
26.5% of the subjects achieved a 5% or greater BMI reduction compared to 15.7% in the 
placebo group. The placebo-corrected BMI reduction was about 0.86 kg/m2.  
There are limited trials for weight reduction in the adolescent population, ages 12 to 17 years
(Peirson, et al, 2015).  Thirty-one studies (29 behavioral, 2 pharmacological and behavioral) 
were included in a meta-analysis of randomized studies conducted in primary care centers in 
overweight and obese children and youth ages 2 to 18 years using behavioral (diet, exercise,
and lifestyle) and pharmacological interventions and providing 6-month postbaseline BMI or 
prevalence of overweight or obesity. Both interventions showed a significant effect on BMI 
in favor of treatment (behavioral: 
standardized mean difference [SMD] -0.54, 
95% confidence interval [CI]
-0.73, -0.36; orlistat plus behavioral: 
SMD -0.43, 
95% CI -0.60, -0.25). The studies reported no significant difference between groups in the 
likelihood of reduced prevalence of overweight or overweight and obese. A great deal of

variation was noted across efficacious interventions.
In conclusion, this meta-analysis 
demonstrated low-quality evidence that behavioral treatments alone are associated with a 
smaller effect in terms of reduced BMI compared with the effect shown by combined 
behavioral and pharmacological interventions. This may be because the effect size in the 
randomized, double blind, placebo controlled, phase 3 orlistat study in adolescents was 
relatively low and there was a lack of maintenance effect. These subjects started to regain 
their BMI after 6 months of treatment. At end of the study, only 26.5% of subjects achieved 
a 5% or greater BMI reduction compared to 15.7% in placebo group. In a sibutramine 
Phase 3 study in obese adolescents, a substantially higher proportion of subjects (69%) 
treated with sibutramine achieved at least a 5% BMI reduction compared to 21% of subjects 
in the placebo group. In addition, sibutramine resulted in a substantial reduction in mean 
BMI (between-group difference, 2.9 kg/m2) and mean weight (between-group difference, 
8.4 kg) compared to placebo (Berkowitz, et al, 2006).  Unlike the weight loss effect of Belviq
in adults and sibutramine in adolescents, subjects in the orlistat study started to increase their 
BMI after 6 months of treatment.
In this study, it is assumed that treatment with Belviq XR 20 mg will lead to a BMI reduction
of more than 1 kg/m2, and a higher proportion of subjects will achieve more than a 5% and 
10% BMI reduction compared to placebo.  A between-group difference of 24% is the basis 
for the conservative assumption of a 20% effect size in the current study.
In addition, the total sample size of 260 subjects will be adequate to assess safety and 
exposure based on previous adolescent studies with weight management products (orlistat 
sibutramine, and liraglutide 3 mg) (FDA, 2003; Chanoine, et al., 2005; Berkowitz, et al,
2006; CT.gov NCT02918279) and other metabolic or dyslipidemia medication products
(ezetimibe, simvastatin) (FDA, 2007).  (revised per Amendment 02)

INVESTIGATIONAL PLAN
9.1
Overall Study Design and Plan
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in 
obese adolescents ages 12 to 17 years.  Approximately 260 subjects will be randomized in a 
1:1 ratio to Belviq XR 20 mg QD (130 subjects) and placebo (130 subjects).  Subjects will be 
stratified by sex.  Subjects will receive Belviq XR 20 mg or matched placebo QD in a 1:1 
ratio for up to 52 weeks. A recruitment plan will be developed to ensure at least 20% of 
younger subjects (12 to 13 years of age) are enrolled in the study.  Throughout the duration 
of the study, subjects will be encouraged to adhere to a lifestyle modification program that 
includes a standardized, age-appropriate diet and exercise counseling (see Appendix 2).  
(revised per Amendments 02 and 03)
The study will consist of 2 phases:
Prerandomization and Randomization.  The 
Prerandomization Phase will last up to 30 days and consists of 1 visit during which subjects 
will be screened for eligibility.  The Randomization Phase consists of a Treatment Period and 
a Follow-Up Period.  The Treatment Period will last for a maximum of 52 weeks, with visits 
at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52; the Follow-Up Period will extend from the 
End of Treatment (EOT) visit to the End of Study (EOS) visit.
Subjects who screen fail can be rescreened only once.  All subjects will continue in the study 
until the 52-week evaluation is completed.  Subjects who discontinue treatment prematurely 
will be followed up until study completion.  All attempts will be made to capture height and 
weight in all subjects whether or not they are still on study drug at the end of the study.  
(revised per Amendments 03 and 04)
Study sites will be selected to ensure adequate representation of adolescents of ethinic and 
racial minorities.  (revised per Amendment 03)
A Data Monitoring Committee (DMC) will be established to monitor and conduct periodic 
safety review of unblinded data. DMC members will be chosen based on their expertise in 
evaluating these clinical events. A separate DMC charter will be established.  (revised per 
Amendment 03)
9.1.1
Prerandomization Phase
Screening will occur during the Prerandomization Phase at Visit 1.
9.1.1.1
Screening Period
The purpose of the Screening Period is to obtain the informed consent and assent and to 
establish protocol eligibility.  Procedures to be followed when obtaining informed consent 
are detailed in Section 5.3.  Careful initial screening is important in the recruitment of 
families who both fully understand the requirements of this 1 year, randomized, controlled 
trial and are truly interested in participation.  Interested caregivers and adolescents will be 
screened by phone to assess preliminary entry criteria.  Candidates will be given a brief

description of the program and general study requirements, with an adolescent and a 
caregiver who is willing to participate.  If preliminary entry criteria are met, adolescents and 
their caregivers will be invited to an initial in-clinic meeting to further discuss the study.  A 
complete description of the study including assessments, the number of visits, the lifestyle 
program, the fact that the adolescent would be taking either the study drug or a placebo, the
duration of the study, and the necessity of having an adolescent wishing to participate as well 
as a participating caregiver will be described.  Consent and assent will be obtained and copies 
of the signed forms will be provided to families.  The importance of the study and its 
scientific merit will be discussed.  Ineligible adolescents will be referred to local weight 
management resources.  Screening period assessments and timing thereof are shown in 
Section 9.5.2.
9.1.2
Randomization Phase
The Randomization Phase will consist of 2 periods: the Treatment Period and the Follow-Up 
Period. The Treatment Period assessments and timing thereof are shown in Section 9.5.2.

Discussion of Study Design, Including Choice of Control Groups
The proposed dose and dosing frequency of Belviq XR in this study is 20 mg QD.  The PK 
parameters of a single 10-mg dose of Belviq were evaluated in healthy, adolescent obese 
subjects in Study APD356-025.  Overall, the PK parameters of Belviq and its main 
metabolites, M1 and M5, were similar to those in adults.  Following a single, oral 
administration of Belviq 10 mg to a total of 8 healthy adolescent (ages 12 to 17 years old) 
obese subjects, the mean maximum concentration observed and the area under the 
concentration-time curve from time zero to infinity (AUC(0-inf)) were 36.5 ng/mL and 
464 hr×ng/mL, respectively.  The mean Belviq terminal phase half-life was 9.70 hours, 
similar to that observed in adults, thus supporting a similar dosing frequency (QD) in 
adolescent subjects.
Additionally, a single dose PK study in 8 healthy obese pediatric subjects ages 6 to 11 years 
of age was performed. The PK analysis after a single 10-mg dose of lorcaserin revealed that 
the lorcaserin AUC(0-inf) values tended to increase with decreasing body weight and age.
However, the body weight normalized AUC(0-inf) values were similar across the age groups, 
therefore the data indicated no effect of age on the lorcaserin PK. Integrated assessment of 
the PK versus body weight relationship, pooling the data from pediatric and adult subjects 
from previous studies, suggested that the lorcaserin area under the curve values for subjects 
with body weight of at least 60 kg overlapped with the area under the curve values from 
adolescents and adults. Therefore, no dose adjustment relative to adults and adolescents is 
deemed necessary for pediatric or adolescent subjects with a body weight of at least 60 kg.
Based on CDC growth charts, the likelihood of subjects who are older than 12 years of age 
having a body weight of less than 60 kg is very low; therefore, the current study as designed

to enroll subjects between 12 to 17 years of age with body weight at least 60 kg, will cover
majority of the population of interest.  The targeted study population comprises 260 obese 
adolescents 12 to 17 years of age, with a body weight at least 60 kg.  (revised per 
Amendment 02)
Obese adolescents will be identified using gender- and age-specific BMI measurement.  
Obesity in adolescents is defined by US Expert committee recommendations as BMI in or 
above the 95th percentile (Barlow, 2007).
Randomization will be used in this study to avoid bias in the assignment of subjects to 
treatment, to increase the likelihood that known and unknown subject attributes 
(eg, demographics, baseline characteristics) are balanced across treatment groups, and to 
ensure the validity of statistical comparisons across treatment groups.  Blinding to treatment 
will be used to reduce potential bias during data collection and evaluation of endpoints.
9.3
Selection of Study Population
Approximately 500 subjects will be screened to ensure that 260 subjects will be randomized.  
(revised per Amendment 02)
Subjects who do not meet all inclusion criteria or do meet any exclusion criteria will not be 
eligible to receive study drug. Subjects who screen fail can be rescreened only once and
without repeating the screening echocardiogram for up to 90 days after the previous 
echocardiogram.  All other screening assessments must be repeated when a subject is 
rescreened.  Subjects that rescreen more than 90 days after the previous echocardiogram must 
repeat all screening assessments including the screening echocardiogram.  (revised per 
Amendments 03 and 04)
9.3.1
Inclusion Criteria
Subjects must meet all of the following criteria to be included in this study:
1. Healthy male or female adolescents, ages 12 to 17 years old (inclusive) at Screening, with 
an initial BMI that is greater than or equal to the United States (US)-weighted mean of 
the 95th percentile based on age and sex with a body weight greater than 60 kg.  Subjects 
with T2DM may have a pre-existing or new diagnosis of T2DM.  
Subjects with pre-existing T2DM should have prior documentation consistent with the 
diagnosis and/or be on active pharmacotherapy for T2DM.  
Subjects with a new diagnosis of T2DM (ie, diagnosed at Screening) should be based on 
the 2016 American Diabetes Association (ADA) guidelines.  The diagnostic criteria are 
met if a subject has unequivocal hyperglycemia (random plasma glucose ≥200 mg/dL 
(11.1 mmol/L) with classic symptoms of hyperglycemia or hyperglycemic crisis) OR any 
of the following criteria are observed and then confirmed:
o
HbA1c ≥6.5% 
o
fasting plasma glucose (FPG) ≥126 mg/dL (7.0 mmol/L)

Page 33 of 85
o
2-hour plasma glucose ≥200 mg/dL (11.1 mmol/L) by an oral glucose tolerance 
test (OGTT)
All T2DM subjects must have an HbA1c <10% at Screening.  If subjects are being or 
need to be treated with antidiabetic agents, the T2DM treatment regimen must be stable 
for at least 3 months before randomization.  A single rescreen is allowed following 
stabilization.  Stable control refers to minimal dose changes to existing medications for 
glycemic control and no medications being initiated for glycemic control in the 3 months 
before Randomization.  Minimal changes are defined as a change without any change in 
dose frequency, no add-on or discontinuation of other antidiabetic agents, and the subject 
has not been hospitalized due to hypo- or hyperglycemic events.  (revised per 
Amendment 03)
2. Subjects and their families are not planning to move away from the area for the duration 
of the study
3. Able and willing to comply with all aspects of the study, including a standardized,
reduced-calorie diet and an age-appropriate, increased physical activity program
4. Considered in stable health in the opinion of the investigator
5. Caregivers or guardians meet the following requirements:
a.
Able and willing to support and supervise study participation in the opinion of the 
investigator, including consideration of any existing physical, medical, or mental 
condition that prevents compliance with the protocol
b. Able and willing to personally comply with and execute all aspects of the study 
requirements for the caregivers or guardians
9.3.2
Exclusion Criteria
Subjects who meet any of the following criteria will be excluded from this study:
1. Clinically significant new illness within 1 month before randomization that may affect 
the subject’s ability to fulfill the study requirements or significantly confound the 
assessments
2. Who cannot swallow investigational products
3. With T2DM who have hypoglycemia unawareness (revised per Amendment 03)
4. Any of the following findings on screening echocardiography:

Aortic regurgitation mild or greater

Mitral regurgitation moderate or greater

Mitral or aortic valve stenosis greater than mild (ie, aortic stenosis [AS]: jet >3.0 m/s, 
mean gradient >25 mm Hg, and aortic valve area [AVA] <1.5 cm2; MS: mean 
gradient >5 mm Hg and mitral valve area [MVA] <1.5 cm2)

Systolic pulmonary artery pressure
(SPAP) >40 mm Hg (and/or tricuspid 
regurgitation (TR) jet velocity >2.9 m/s)
-
In cases where an actual SPAP value is not measurable due to lack of adequate 
TR jet, the pulmonary flow acceleration time measured at the right ventricular 
outflow tract (RVOTAT), will be used to assess eligibility.   Subjects with a

9.4.2.4
Storage Conditions
Where applicable, investigational product will be stored in accordance with the DEA 
Regulations for Scheduled III to V Drugs and labeled storage conditions.  Temperature 
monitoring is required at the storage location to ensure that the study drug is maintained 
within an established temperature range.  The investigator or designee is responsible for 
ensuring that the temperature is monitored throughout the total duration of the study and that 
records are maintained; the temperature should be monitored continuously by using either an 
in-house validated data acquisition system, a mechanical recording device, such as a 
calibrated chart recorder, or by manual means, such that minimum and maximum 
thermometric values over a specific time period can be recorded and retrieved as required.
9.4.3
Method of Assigning Subjects to Treatment Groups
Subjects will be assigned to treatments based on a computer-generated randomization 
scheme that will be reviewed and approved by an independent statistician.  The 
randomization scheme and identification for each subject will be included in the final clinical 
study report for this study.
Subjects will be centrally stratified by sex (male and female).  Within each stratum, subjects 
will be randomized to receive either Belviq XR 20 mg or placebo QD in a 1:1 ratio.

Randomization will be performed centrally by an interactive voice or web response system 
(IxRS).  The IxRS or clinical supply vendor will generate the randomized identification
numbers to be included on study packaging.  Upon signature of the ICF, the investigator or 
designee will access the IxRS to register the subject information.  At Randomization, the 
IxRS will assign each subject a unique randomization number.  At each subsequent visit 
during the Treatment Period and Follow-Up Period, the investigator or designee will access 
IxRS to obtain dispensing information and to register the subject’s visit.
9.4.4
Selection and Timing of Dose for Each Subject
Subjects should take the study medication once daily at approximately the same time of 
every day, and be encouraged to take the study medication with an adequate amount of water 
(8 oz. or 240 mL).  For information on dosing on visits associated with PK sampling, see 
Section 9.5.1.4.1.  (revised per Amendment 03)
9.4.5
Blinding
During the Randomization Phase, subjects and all personnel involved with the conduct and 
interpretation of the study, including investigators, site personnel, and sponsor staff will be 
blinded to the treatment codes.  Randomization data will be kept strictly confidential, filed 
securely by an appropriate group with the sponsor or CRO, and accessible only to authorized 
persons (eg, Eisai Global Safety) until the time of unblinding, per the SOP.
A master list of all treatments and the subject numbers associated with them will be 
maintained in a sealed envelope by the clinical supply vendor, the IxRS vendor, and the 
sponsor.  In the event that emergency conditions require knowledge of the study treatment 
given, the blind may be broken via the code breaker facility within the IxRS.  Emergency 
procedures for revealing drug codes are given in Section 9.5.4.5.  If possible, before breaking 
the blind, the investigator should consult with the sponsor or designee to ascertain the 
necessity of breaking the code.
9.4.6
Prior and Concomitant Therapy
Any medication (including OTC medications) or therapy administered to the subject during 
the study (starting at the date of informed consent) will be recorded on the Prior and
Concomitant Medication Case Report Form (CRF) or Non-Pharmacological Procedures 
CRF.  The investigator will record on the Adverse Event CRF any AE for which the 
concomitant medication/therapy was administered. If the concomitant medication/therapy is 
being administered for a medical condition present at the time of entry into the study, the 
investigator will record the medical condition on the Medical History and Current Medical 
Condition CRF.

The following concomitant medication guidelines/restrictions will apply:

Medications for the treatment of hypertension, dyslipidemia, or diabetes may be 
started, discontinued, or adjusted during the study according to local standards of care 
if, in the judgment of the investigator or the subject’s physician, such a change is 
medically indicated.

For diabetic subjects treated with sulfonylureas, insulin (note that subjects should not 
be enrolled as indicated in exclusion criteria), or other antidiabetic agents with 
hypoglycemic risk, the risk of hypoglycemic events may be higher if the subjects 
experience rapid and significant weight loss (more than 10% weight reduction than at 
the previous visit).  It is recommended that the physician advise the subject to 
monitor their blood glucose more frequently and adjust their antidiabetic medications 
and diet accordingly.


The antihyperglycemic medication dose would be considered for reduction in the 
event of 1 documented and otherwise unexplained hypoglycemic event (blood 
glucose concentration <65 mg/dL) or 2 undocumented and otherwise unexplained 
suspected hypoglycemic events between any 2 scheduled visits.  For subjects on more 
than 1 antihyperglycemic medication, it is recommended to reduce insulin first (if 
applicable), then the oral and/or other injectable antidiabetic agents.  If the previous 
criteria are met again following dose reduction, further dose reductions or cessation 
of 1 or more antihyperglycemic agents, are suggested.  See Section 9.5.4.2 for the 
definition and reporting of hypoglycemic events. 
To minimize the risk of cardiac valve toxicity, subjects must not initiate use of agents that 
have documented correlation with increased incidence of valvulopathy and/or PH (eg, 
pergolide, ergotamine, methysergide, or cabergoline) during the study. 
(revised per 
Amendment 01)  If any of the above agents are clinically warranted, and subjects initiate any 
of these agents, Belviq XR should be discontinued but can be restarted on Belviq XR after 
being off the medications above for 1 month.  Otherwise, the study medication should not be 
restarted, but the subject should continue all study visits.  (revised per Amendments 03 and 
04)
9.4.7
Treatment Compliance
Records of treatment compliance for each subject will be kept during the study.  Subjects will 
be asked to bring their study drug bottles to each visit.  The CRAs will review treatment 
compliance during site visits and at the completion of the study.  (revised per 
Amendment 03)
Per visit schedule, subjects will return unused study drug and be given a new supply; pill 
counts will be made by study staff on returned medication.

assessed.  (revised per Amendments 03 and 04)
Bone mineral density and content, total body fat mass and total body lean mass will be 
determined using DEXA in a subset of subjects (selected prior to randomization at selected 
sites).  (revised per Amendment 03)
9.5.1.5.1
ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered an investigational product.  An AE does not necessarily have a causal

relationship with the medicinal product.  For this study, the study drug is Belviq XR
(lorcaserin hydrochloride).
The criteria for identifying AEs in this study are:
•
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or 
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE)
•
Any new disease or exacerbation of an existing disease 
•
Any deterioration in non-protocol-required measurements of a laboratory value or other 
clinical test (eg, ECG, x-ray) that results in symptoms, a change in treatment, or 
discontinuation of study drug
•
Recurrence of an intermittent medical condition (eg, headache) not present at 
pretreatment (baseline)
•
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of study drug, or withholding 
of study drug, whether prescribed in the protocol or not.
All AEs observed during the study will be reported on the Adverse Event CRF.  All AEs, 
regardless of relationship to study drug or procedure, should be collected beginning from the 
time the subject signs the study ICF through the last visit in the Treatment Phase.  Subjects 
who fail screening primarily due to AE(s) must have the AE(s) leading to screen failure 
reported on the Screening Disposition CRF.  SAEs will be collected for 28 days after the last 
dose.
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute 
an AE.  Medical and scientific judgment should be exercised in deciding whether an isolated 
laboratory abnormality should be classified as an AE.  Any laboratory abnormality 
considered to constitute an AE should be reported on the Adverse Event CRF. 
Abnormal ECG (corrected QT interval [QTc]) results, if not otherwise considered part of a 
clinical symptom that is being reported as an AE, should be considered an AE if the QTc 
interval is greater than 450 msec and there is an increase of more than 60 msec from baseline.  
Any ECG abnormality that the investigator considers as an AE should be reported as such.
At each visit, the investigator should actively assess as to whether any of the following 
adverse events have occurred during the interval since the last visit:
•
Serotonin syndrome and signs or symptoms of serotonergism
•
Signs or symptoms of valvular heart disease or pulmonary hypertension, including 
dyspnea, dependent edema, congestive heart failure, or a new cardiac murmur

•
Impairments in attention and memory, and confusion, somnolence, and fatigue
•
Psychiatric disorders
•
Hypoglycemia in subjects with diabetes on concomitant antidiabetes medications (using 
ADA definitions)
•
Priapism and hyperprolactinemia signs and symptoms should be recorded at each visit 
and whenever reported
•
Hypersensitivity reactions
Any such events should be recorded as adverse events.  Serotonin syndrome, valvular heart 
disease, pulmonary hypertension, and priapism should always be reported as serious adverse 
events (SAEs) (See Section 9.5.1.5.2 for a complete list of adverse events that should always 
be considered as Serious).  (revised per Amendment 03)
Events of hypoglycemia in subjects with diabetes on concomitant antidiabetes medication 
should be captured as per Section 9.5.2.  Severe symptomatic events of hypoglycemia should 
always be reported as an SAE as per Section 9.5.1.5.2.  (revised per Amendment 03)
It is the responsibility of the investigator to review the results of the Leiter-3, C-SSRS, and 
PHQ-9 for all subjects and determine if any result constitutes an AE.  Medical and scientific 
judgment should be exercised in deciding whether an isolated suicidality rating scale 
response should be classified as an AE (see Section 9.5.1.5.10 for a description of the 
C-SSRS).  (revised per Amendment 01)
All AEs must be monitored until symptom resolution, or until the condition stabalizes.  
(revised per Amendment 03)
Every effort must be made by the investigator to categorize each AE according to its 
severity and its relationship to the study treatment.
Assessing Severity of Adverse Events
Adverse events will be graded on a 3-point scale (mild, moderate, severe) and reported in the 
detail indicated on the CRF.  The definitions are as follows:
Mild
Discomfort noticed, but no disruption of normal daily activity
Moderate Discomfort sufficient to reduce or affect normal daily activity
Severe
Incapacitating, with inability to work or to perform normal daily activity
The criteria for assessing severity are different than those used for seriousness (see
Section 9.5.1.5.2 for the definition of an SAE).
Assessing Relationship to Study Treatment
Items to be considered when assessing the relationship of an AE to the study treatment are:

•
Temporal relationship of the onset of the event to the initiation of the study treatment
•
The course of the event, especially the effect of discontinuation of study treatment or 
reintroduction of study treatment, as applicable
•
Whether the event is known to be associated with the study treatment or with other 
similar treatments
•
The presence of risk factors in the study subject known to increase the occurrence of the 
event
•
The presence of nonstudy, treatment-related factors that are known to be associated with 
the occurrence of the event
Classification of Causality
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question:
Is there a reasonable possibility that the study drug caused the AE?
Yes (related)
A causal relationship between the study drug and the AE is a reasonable 
possibility.
No (not related) A causal relationship between the study drug and the AE is not a 
reasonable possibility.
9.5.1.5.2
SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An SAE is any untoward medical occurrence that at any dose:
•
Results in death
•
Is life-threatening (ie, the subject was at immediate risk of death from the AE as it 
occurred; this does not include an event that, had it occurred in a more severe form or 
was allowed to continue, might have caused death)
•
Requires inpatient hospitalization or prolongation of existing hospitalization
•
Results in persistent or significant disability/incapacity
•
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug)
Other important medical events that may not be immediately life-threatening or result in 
death or hospitalization but, when based on appropriate medical judgment, may jeopardize 
the subject or may require intervention to prevent one of the outcomes in the definition of 
SAE listed above should also be considered SAEs.  Medical and scientific judgment should 
be exercised in deciding whether expedited reporting is appropriate in such situations. 
For this study, the following events should always be considered serious and reported as an 
important medical event if it does not meet other serious criteria:

•
Serotonin syndrome (must have at least 1 of the following: 
Spontaneous clonus; 
Inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus)
•
Psychosis
•
Suicidal behavior
•
Priapism
•
New onset valvular heart disease
•
New onset pulmonary hypertension
•
Malignant neoplasms (revised per Amendment 03)
•
Fibroadenomas of the breast or ductal carcinoma in situ
•
Severe symptomatic hypoglycemia (revised per Amendment 03)
In addition to the above, events associated with special situations include pregnancy or 
exposure to study drug through breastfeeding; AEs associated with study drug overdose, 
misuse, abuse, or medication error.  These events associated with special situations are to be 
captured using the SAE procedures but are to be considered as SAEs only if they meet 1 of 
the above criteria.  All AEs associated with special situations are to be reported on the CRF 
whether or not they meet the criteria for SAEs.  
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization.
The following hospitalizations are not considered to be SAEs because there is no “AE” (ie, 
there is no untoward medical occurrence) associated with the hospitalization:
•
Hospitalizations for respite care
•
Planned hospitalizations required by the protocol  
•
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed after study drug administration)
•
Hospitalization for administration of study drug or insertion of access for administration 
of study drug
•
Hospitalization for routine maintenance of a device (eg, battery replacement) that was in 
place before study entry

VITAL SIGNS AND WEIGHT MEASUREMENTS
Vital sign measurements (ie, systolic and diastolic BP [mmHg], pulse [beats per minute], 
respiratory rate [per minute], body temperature [in centigrade]), and weight (kg) will be 
obtained as designated in the Schedule of Procedures/Assessments (Table 2) by a validated 
method.  BP and pulse will be measured after the subject has been sitting for 5 minutes.  All 
BP measurements should be performed on the same arm, preferably by the same person. 
When vital signs are to be obtained concurrently with PK or other blood samples, the vital 
sign measurements will be performed before drawing blood samples in order to maximize the 
accuracy of blood sampling times while minimizing the potential effects of blood drawing on 
recordings obtained during safety assessments.

9.5.1.5.10 OTHER SAFETY ASSESSMENTS
Leiter-3
The Leiter International Performance Scale–Third Edition (Leiter-3) is widely used 
non verbal measure of intelligence, memory, and attention in those between the ages of 3 and 
75 years. 
The Attention/Memory Battery consists of 5 subtests: 2 measure nonverbal 
attention; 2 measure memory; and 1 measures cognitive interference (nonverbal Stroop test). 
These subtests are combined to produce a Memory and Processing Speed composite scores, 
normalized to a mean of 100 and standard deviation of 15. The Leiter-3 will be used to 
assess lorcaserin effects on cognition, specifically, attention and memory. In addition, signs 
and symptoms of cognition-related AEs, including impairments in attention, memory, and 
adverse effects on schoolwork will be captured in the eCRF. (revised per Amendment 01)
PHQ-9
The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and 
measuring the severity of depression:

The PHQ-9 incorporates Diagnostic and Statistical Manual of Mental Disorders, 4th 
Edition (DSM-IV) depression diagnostic criteria with other leading major depressive 
symptoms into a brief self-report tool.

The tool rates the frequency of the symptoms which factors into the scoring severity 
index.

Question 9 on the PHQ-9 screens for the presence and duration of suicide ideation.

A follow-up, non-scored question on the PHQ-9 assigns weight to the degree to which 
depressive problems have affected the subject’s level of function. 
C-SSRS
The C-SSRS collects information pertinent to suicidal ideation and actions.  It consists of a 
Baseline version which will be administered at Baseline and a Since Last Visit version which 
will be administered at the remaining visits.  C-SSRS will be used to assess signal of 
depression and suicidal ideation or behavior. Qualified personnel must evaluate positive 
responses on the C-SSRS and take appropriate action as detailed in the training and

certification process for administering the C-SSRS.  It will be performed at Screening and at 
study visits as designated in the Schedule of Procedures/Assessments (Table 2). (revised per 
Amendment 01)
DEXA for the Assessment of Bone Mineral Density
Bone mineral density body composition determination by DEXA whole body composition, to 
include bone mineral density and content, total body fat mass and total body lean mass will 
be determined using DEXA in a subset of subjects (selected prior to randomization at 
selected sites).  A contracted vendor will provide all administration and project management 
services for DEXA scanning.  This will include site and image data management services, as 
well as site training and certification.  (revised per Amendment 03)
A mininum of 30 subjects ages 12-17 years (selected prior to randomization at selected sites) 
should have bone density evaluated with DEXA at baseline and week 52/EOT.  (revised per 
Amendments 03 and 04)
Hand X-Ray
A hand x-ray for evaluation of any potential negative effect on bone age will be performed 
on the same hand at each visit as designated in the Schedules/Assessments (Table 2).  
(revised per Amendment 01)
Tanner Staging
The pubic hair growth (both sexes), genital (males only) and breast (females only) 
development of subjects will be using Tanner Staging by a trained clinician (Marshall, 1970).
Subjects will be examined by the investigator as designated in the Schedules/Assessments 
(Table 2). (revised per Amendments 01 and 03)
Echocardiogram
Echocardiograms will be obtained on the Schedule of Procedures/Assessments (Table 2). 
Valvular regurgitation in echocardiogram will be rated absent, trace, mild, moderate, or 
severe for the aortic, mitral, and tricuspid valves; the rating will be absent or present for the 
pulmonic valve.  The evaluations will be based on guidelines from the American Society of 
Echocardiography. Pulmonary artery systolic pressure will be estimated from the TR
regurgitant jet velocity.  (revised per Amendment 03)

dosing) and 1 within 1 to 3 hours after dosing. Dose times must be recorded for the last 2 dosing times before the day of clinic visit. Week 52 PK samples should only be 
collected if the sample can be drawn within 60 hours of the last dose of study drug.  On the day of the Week 36 clinic visit, subjects will take the morning dose at home, and 
will be asked to visit the clinic within 4 to 6 hours of dosing that day, during which 1 blood sample for PK assessments will be collected  Dose times must be recorded for the 
last 2 dosing times prior to the clinic visit. (revised per Amendment 01)
g: PK samples should only be collected if the sample can be drawn within 60 hours of the last dose of study drug.
h: PK samples should only be collected if subject has experienced an SAE while on study drug and the sample can be drawn within 60 hours of the initiation of the SAE.
i: Echocardiographic assessments will be performed during screening period after subjects have met all other inclusion and exclusion criteria.
j: Only subjects in selected sites will have this assessment done.  (revised per Amendment 03)
k: Lifestyle modification counseling will also be performed at Weeks 3, 16, 24, 32, 40, and 48 in addition to counseling at the scheduled visits in Appendix 2.

safety.
9.5.4
Reporting of Serious Adverse Events, Pregnancy, and Events Associated 
with Special Situations
9.5.4.1
Reporting of Serious Adverse Events
All SAEs, regardless of their relationship to study treatment, must be reported on a 
completed SAE form by email or fax as soon as possible but no later than 1 business 
day from the date the investigator becomes aware of the event.
SAEs, regardless of causality assessment, must be collected through the through the last visit
and for 28 days after the subject’s last dose.  All SAEs must be followed to resolution or, if 
resolution is unlikely, to stabilization.  Any SAE judged by the investigator to be related to 
the study treatment or any protocol-required procedure should be reported to the sponsor 
regardless of the length of time that has passed since study completion.
The detailed contact information for reporting of SAEs is provided in the Investigator Study 
File.
For urgent safety issues, please ensure all appropriate medical care is administered to the 
subject and contact the appropriate study team member listed in the Investigator Study File.
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report.  This includes the investigator’s assessment of causality.
Any follow-up information received on SAEs should be forwarded within 1 business day of 
its receipt.  If the follow-up information changes the investigator’s assessment of causality, 
this should also be noted on the follow-up SAE form.
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested by 
the sponsor.
The investigator must notify his/her IRB/IEC of the occurrence of the SAE, in writing, if 
required by their institution.  A copy of this communication must be forwarded to the sponsor 
to be filed in the sponsor’s Trial Master File.
9.5.4.2
Reporting of Pregnancy and Exposure to Study Drug through Breastfeeding
Any pregnancy in which the estimated date of conception is either before the last visit or 
within 28 days of last study treatment or any exposure to study drug through breastfeeding 
during study treatment or within 28 days of last study treatment must be reported.

If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, this 
should be reported regardless of the length of time that has passed since the exposure to study 
treatment.
A congenital anomaly, death during perinatal period, an induced abortion, or a spontaneous 
abortion are considered to be an SAE and should be reported in the same time frame and in 
the same format as all other SAEs (see Section 9.5.4.1).
Pregnancies or exposure to study drug through breastfeeding must be reported by fax or 
email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy.  The contact information for the reporting of pregnancies 
and exposure to study drug through breastfeeding is provided in the Investigator Study File.  
The Pregnancy Report Form must be used for reporting.  All pregnancies must be followed to 
outcome.  The outcome of the pregnancy must be reported as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the outcome.
A subject who becomes pregnant must be withdrawn from the study. 
9.5.4.3
Reporting of Events Association with Special Situations
9.5.4.3.1
REPORTING OF ADVERSE EVENTS ASSOCIATED WITH STUDY DRUG OVERDOSE,
MISUSE, ABUSE, OR MEDICATION ERROR
Adverse events associated with study drug overdose, misuse, abuse, and medication error 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication error are defined as follows:
Overdose
Accidental or intentional use of the study drug in an amount higher
than the protocol-defined dose
Misuse
Intentional and inappropriate use of study drug not in accordance with 
the protocol or authorized dose, route of administration, or 
indication(s) or use of prescription-only study drug without a 
prescription
Abuse
Sporadic or persistent intentional excessive use of study drug 
accompanied by harmful physical or psychological effects
Medication error
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of the 
healthcare professional, subject, or consumer.  Such events may be 
related to professional practice, healthcare products, occupational 
exposure, procedures, or
systems,
including prescribing,
order 
communication,
product
labeling, 
packaging, 
nomenclature,
compounding,
dispensing,
distribution,
administration, education,
monitoring, or use.

All AEs associated with overdose, misuse, abuse, or medication error should be captured on 
the Adverse Event CRF and also reported using the procedures detailed in Section 9.5.4.1
even if the AEs do not meet serious criteria.  Abuse is always to be captured as an AE.  If the 
AE associated with an overdose, misuse, abuse, or medication error does not meet serious 
criteria, it must still be reported using the SAE form and in an expedited manner but should 
be noted as nonserious on the SAE form and the Adverse Event CRF.
9.5.4.3.2
REPORTING OF STUDY-SPECIFIC EVENTS
Study-specific events (listed below) should always be considered as serious important 
medical events and be entered on the Adverse Event CRF and reported using the procedures 
detailed in Reporting of Serious Adverse Events (Section 9.5.4.1), even if the study-specific 
event does not meet other serious criteria.  

Serotonin syndrome
Must have at least 1 of the following: 
spontaneous clonus; 
inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus

Psychosis

Suicidal behavior 

Priapism

New onset of valvular heart disease

New onset pulmonary hypertension

Malignant neoplasms (revised per Amendment 03)

Fibroadenomas of the breast or ductal carcinoma in situ

Severe symptomatic hypoglycemia (revised per Amendment 03)
Subject-reported episodes of hypoglycemia or decreased blood sugar should be captured on 
the eCRF according to the following guidelines:

Pseudo-hypoglycemia:  An event during which the person with diabetes reports any of 
the typical symptoms of hypoglycemia and interprets those as indicative of hypoglycemia 
with a measured plasma glucose concentration >70 mg/dL (>3.9 mmol/L) but 
approaching that level.  (revised per Amendment 03)

Probable symptomatic hypoglycemia:  An event during which symptoms typical of 
hypoglycemia are not accompanied by a plasma glucose determination but that was 
presumably caused by a plasma glucose concentration ≤ 70 mg/dL (≤ 3.9 mmol/L)
(revised per Amendment 03)

Asymptomatic hypoglycemia: 
An event not accompanied by typical symptoms of 
hypoglycemia but with a measured plasma glucose concentration ≤ 70 mg/dL (≤ 
3.9 mmol/L) (revised per Amendment 03)


Documented symptomatic hypoglycemia: An event during which typical hypoglycemia 
symptoms are accompanied by a measured plasma glucose ≤70 mg/dL (≤3.9 mmol/L) 
(revised per Amendment 03)

Severe hypoglycemia: 
An event requiring assistance of another person to actively 
administer carbohydrate, glucagon or other resuscitation actions. Plasma glucose 
measurements may not be available during such an event, but neurological recovery 
attributable to the restoration of plasma glucose to normal is considered sufficient 
evidence that the event was induced by a low plasma glucose concentration (revised per 
Amendment 03)
See Section 9.4.6 (Prior and Concomitant Therapy) for directions on the recommendations 
for possible adjustment to antihyperglycemic medication doses in response to reported 
episodes of hypoglycemia.  (revised per Amendment 03)
9.5.4.4
Expedited Reporting
The sponsor must inform investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (ie, within 
specific time frames).  For this reason, it is imperative that sites provide complete SAE 
information in the manner described above.
9.5.4.5
Breaking the Blind
In the case of a medical emergency where the appropriate treatment of the subject requires 
knowledge of the study treatment given, the investigator may break the randomization code 
for an individual subject.  In all such cases, the AE necessitating the emergency blind break 
will be handled as an SAE in accordance with the procedures indicated above.  Any broken 
code will be clearly justified and documented.  The medical monitor must be notified 
immediately of the blind break.
9.5.4.6
Regulatory Reporting of Adverse Events
Adverse events will be reported by the sponsor or a third party acting on behalf of the 
sponsor to regulatory authorities in compliance with local and regional law and established 
guidance.  The format of these reports will be dictated by the local and regional 
requirements.
9.5.5
Completion/Discontinuation of Subjects
The investigator may withdraw the subject from the study at any time for safety or 
administrative reasons.  A subject may elect to discontinue the study at any time for any 
reason.  All subjects will continue in the study until the 52-week evaluation is completed.  
Subjects who discontinue study drug prematurely will continue to be evaluated for all study 
assessments until study completion.  All attempts will be made to capture height and weight 
in all subjects whether or not they are still on IP at the end of the study.  All subjects who 
discontinue the study are to complete the study’s early discontinuation procedures indicated 
in the Schedule of Procedures/Assessments Table 2). (revised per Amendment 03)

The investigator will promptly explain to the subject involved that the study will be 
discontinued for that subject and provide appropriate medical treatment and other necessary 
measures for the subject.  A subject who has ceased to return for visits will be contacted by 
mail, phone, or other means to gather information such as the reason for failure to return, the 
status of treatment compliance, the presence or absence of AEs, and clinical courses of signs 
and symptoms.
Subjects who discontinue early from the study will be discontinued for 1 of these primary 
reasons: AE(s), lost to follow-up, subject choice, withdrawal of consent, pregnancy, study 
terminated by sponsor, or other.  In addition to the primary reason, the subject may indicate
1 or more of the secondary reasons for discontinuation.  Study disposition information will 
be collected on the Subject Disposition CRF. If “lost to follow-up” is recorded in clinical 
database, appropriate queries will be sent to investigators in order to collect all the relevant 
reasons for missing data.  (revised per Amendment 03)
Every effort, including proper training of all study participants and their parent/guardian, 
should be made in order to achieve optimal subject retention and prevent missing data, 
especially for the Week 52 primary endpoint.  A retention plan to help avoid missing data 
will be developed and included in study manual. (revised per Amendment 03)
A subject removed from the study for any reason may not be replaced.
9.5.6
Abuse or Diversion of Study Drug
During the study, the investigator will report any concern about abuse or diversion of study 
drugs by completing the Abuse or Diversion of Study Drug CRF.  The DEA Registrant has 
the responsibility to comply with local, state, and Federal laws to notify the Field Division 
Office of the DEA of any theft or significant loss of any controlled substances upon 
discovery of such theft or loss.
9.5.7
Confirmation of Medical Care by Another Physician
The investigator will instruct subjects to inform site personnel when they are planning to 
receive medical care by another physician.  At each visit, the investigator will ask the subject 
whether he or she has received medical care by another physician since the last visit or is 
planning to do so in the future.  When the subject is going to receive medical care by another 
physician, the investigator, with the consent of the subject, will inform the other physician 
that the subject is participating in the clinical study.
9.6
Data Quality Assurance
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines.  Site audits 
will be made periodically by the sponsor’s or the CRO’s qualified compliance auditing team, 
which is an independent function from the study team responsible for conduct of the study.

Data Collection
Data required by the protocol will be collected on the CRFs and entered into a validated data 
management system that is compliant with all regulatory requirements.  As defined by ICH 
guidelines, the CRF is a printed, optical, or electronic document designed to record all of the 
protocol-required information to be reported to the sponsor on each study subject.
Data collection on the CRF must follow the instructions described in the CRF Completion 
Guidelines.  The investigator has ultimate responsibility for the collection and reporting of all 
clinical data entered on the CRF.  The investigator or designee as identified on Form 
FDA 1572 must sign the completed CRF to attest to its accuracy, authenticity, and 
completeness.
Completed, original CRFs are the sole property of Eisai and should not be made available in 
any form to third parties without written permission from Eisai, except for authorized 
representatives of Eisai or appropriate regulatory authorities.
9.6.2
Clinical Data Management
All software applications used in the collection of data will be properly validated following 
standard computer system validation that is compliant with all regulatory requirements.  All 
data, both CRF and external data (eg, laboratory data), will be entered into a clinical system.
9.7
Statistical Methods
All statistical analyses will be performed by the sponsor or designee after the study is 
completed and the database is locked and released for unblinding.  Statistical analyses will be 
performed using WinNonlin and SAS software or other validated statistical software as

medications will be defined as medications that started on or after the date of the dosing of 
study drug and continued up to 30 days afterward.
9.7.1.6
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, while the PP will 
be used as a supportive analysis.  Unless specified otherwise, a 2-sided α=0.05 significance 
level will be used for all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from baseline to Week 52.  The change 
from baseline in BMI will be analyzed using analysis of covariance model (ANCOVA) with 
factors of treatment, sex (male and female) as fixed effect, and the baseline age and BMI as 
covariates.  The missing values will be imputed using a pattern mixture model utilizing 
multiple imputation (MI) assuming the missing values are missing not at random (MNAR).  
The missing values will be imputed at each visit using all available values including the 
retrieved measurement from the postdiscontinuation data.  The details of the analysis model 
and missing value imputation method will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis: The same primary efficacy analyses described above will be repeated based 
on the PP.

Change from baseline in standardized BMI score (Z-score): The same primary efficacy 
analyses described above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed 
and will be described in the SAP.

Key Secondary Efficacy Analysis
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 
5% BMI reduction at Week 52.  The secondary efficacy endpoint will be analyzed only if the 
test for the primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be 
analyzed using a logistic regression model with factors of treatment, and sex (male and 
female), and baseline BMI as a covariate using FAS.  Subjects with any missing assessment 
at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be 
analyzed using mixed effect model repeated measurement analysis (MMRM) on the FAS for 
study treatment compared to placebo, as appropriate. The model will include all data and will 
include treatment, time, and the interaction of treatment by time as fixed effects, with 
adjustment for sex (male versus female), BMI and age at baseline, and subject as a random 
effect.  (revised per Amendment 03)
Treatment by time interaction will be used to construct the treatment comparisons at a 
specific time.  The MMRM model assumes that the missing data are missing at random and 
makes use of all available data even if a subject has missing data at some postbaseline visits.  
An unstructured covariance matrix will be used, and if the model fails to converge, then an 
autoregressive matrix will be used.  (revised per Amendment 03)
Categorical variables will be analyzed using the Cochran Mantel Haenszel test, Chi-square 
test, or logistic regression as appropriate.  Additional analysis may be performed as needed 
using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male 
and female), race (American Indian or Alaska Native, Asian, Black or African American, 
Native Hawaiian or other Pacific Islander, or White), and age. Additional subgroups may be 
explored, if deemed necessary.  (revised per Amendment 03)
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and 
sensitivity analyses.

PHARMACOKINETIC ANALYSES
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling.  The effect of covariates, such as baseline characteristics
or demographics, on PK will be explored.  Derived exposure parameters such as the 
maximum observed concentration and the area under the concentration-time curve from time
0 to 24 hours at steady-state will be calculated from the final PK model using individual

posterior estimates of the PK parameters and from dosing history.  The PK analysis set will 
be used for this analysis.
9.7.1.7.2
PHARMACODYNAMIC ANALYSES
Change from baseline in BMI will be assessed as the PD endpoint.  The PD analysis set will 
be used for this analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of subjects achieving ≥5% 
and ≥10% BMI reduction, and change in waist circumference from baseline) will also be 
assessed as part of the PD analysis.  The PK/PD analysis set will be used for this analysis.
9.7.1.7.3
PHARMACOKINETIC/PHARMACODYNAMIC ANALYSES
Population PK/PD modeling will be used to explore the relationship between lorcaserin 
plasma exposure and response, including but not limited to change in BMI from baseline and 
the probability of achieving at least a 5% and at least a 10% change in BMI from baseline to 
Week 52.  Additionally, exposure-safety relationships for select safety parameters may be 
explored graphically, depending on the data at the end of study.  Any emergent relationship 
may be modeled as appropriate.  Any parameters based on the study data may be considered 
for exploratory assessment for its relationship to PK.

9.7.1.8
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments 
including the incidence of AEs (including changes from baseline in physical examination, 
neuromuscular sign assessment for serotonin syndrome, and signs and symptoms of priapism 
and hyperprolactinemia), out-of-normal-range laboratory safety test values, change from 
baseline in laboratory safety test values, ECGs, vital sign measurements, bone mineral 
density and content, total body fat mass and total body lean mass by DEXA, FDA-defined 
valvulopathy, and pulmonary hypertension by echocardiograph will be summarized by 
treatment group using descriptive statistics or frequency count as appropriate.  (revised per 
Amendments 01, 03, and 04)
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the first dose of study drug.
9.7.1.8.1
EXTENT OF EXPOSURE
Subjects will receive Belviq XR 20 mg or placebo QD for up to 52 weeks. The extent of 
exposure will be characterized by duration of exposure (in weeks) for each treatment group.
Duration of exposure will be defined as the number of weeks between the date the subject 
received the first dose of study drug and the date the subject received the last dose of study

drug.  Duration of exposure will be summarized using descriptive statistics by treatment 
group.  In addition, the duration of exposure will be categorized and will be summarized 
using frequency count by treatment group.
9.7.1.8.2
ADVERSE EVENTS
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities 
(MedDRA).  Adverse events will be coded to the MedDRA (Version 18.0 or higher) lower 
level term closest to the verbatim term.  The linked MedDRA PT and primary system organ 
class (SOC) are also captured in the database.
A treatment-emergent AE (TEAE) is defined as an AE that emerges during treatment (up to 
28 days after the last dose of study drug), having been absent at pretreatment (baseline) or
•
Reemerges during treatment (up to 28 days after the last dose of study drug), having been 
present at pretreatment (baseline) but stopped before treatment, or 
•
Worsens in severity during treatment relative to the pretreatment state, when the AE is 
continuous.
Only those AEs that were treatment emergent will be included in summary tables.  All AEs, 
treatment emergent or otherwise, will be presented in subject data listings.
The TEAEs will be summarized by treatment group.  The following summaries will be 
reported for TEAES:

Incidence of TEAEs in descending order of frequency

Incidence of TEAEs by SOC and PT

Incidence of treatment-related TEAEs by SOC and PT

Incidence of TEAEs by SOC, PT and maximum severity (mild, moderate, or severe)

Incidence of treatment-related TEAEs by SOC, PT, and maximum severity (mild, 
moderate, or severe)

Incidence of TEAEs by SOC, PT, and relationship to study drug (Yes [related] or No [not 
related]) 
A subject will be counted only once within a SOC or PT, if the subject experienced more 
than 1 TEAE within a specified SOC and PT.


Incidence of treatment-emergent SAE by SOC and PT

Incidence of treatment-related treatment-emergent SAE by SOC and PT
In addition, subjects with TEAEs leading to discontinuation from study drug and AEs of 
special interest as described in Section 9.5.4.3.2 will be summarized by MedDRA SOC and 
PT for each treatment group. 
9.7.1.8.3
LABORATORY VALUES
Laboratory results will be summarized using Système International units, as appropriate.  For 
all quantitative parameters listed in Section 9.5.1.5.3, the actual value and the change from 
baseline to each postbaseline visit and to the end of treatment (defined as the last 
on-treatment value) will be summarized by visit and treatment group using descriptive 
statistics.  Percentages will be based on the number of subjects with both nonmissing 
baseline and relevant postbaseline results.
Laboratory test results will be assigned a low/normal/high (LNH) classification according to 
whether the value was below (L), within (N), or above (H) the laboratory parameter’s 
reference range.  Within-treatment comparisons for each laboratory parameter will be based 
on 3-by-3 tables (shift tables) that compare the baseline LNH classification to the LNH 
classification at the End of Treatment and the Follow-Up visits.  Similar shift tables will also 
compare the baseline LNH classification to the LNH classification for the highest and lowest 
value during the treatment period.
Appendix 1
presents the criteria that will
be used to identify subjects with 
treatment-emergent markedly abnormal laboratory values (TEMAV).  Except for phosphate, 
a TEMAV is defined as a postbaseline value with an increase from baseline to a grade of 2 or 
higher.  For phosphate, a TEMAV was defined as a postbaseline value with an increase from 
baseline to a grade of 3 or higher.  When displaying the incidence of TEMAVs, each subject 
may be counted once in the laboratory parameter high and in the laboratory parameter low 
categories, as applicable.
9.7.1.8.4
VITAL SIGNS
Descriptive statistics for vital signs parameters (eg, systolic and diastolic BP, pulse, 
respiratory rate, temperature, weight) and changes from baseline will be presented by visit
and treatment group.
9.7.1.8.5
ELECTROCARDIOGRAMS
For each ECG parameter (including PR interval, RR interval, QRS interval, QT interval, QTc
interval (Bazett formula), QTc interval (Fridericia formula), and heart rate), the actual value

and change from baseline will be summarized by visit and treatment group using descriptive 
statistics. 
Shift tables will present changes from baseline in ECG interpretation (categorized as normal; 
abnormal, not clinically significant; and abnormal, clinically significant) to end of treatment. 
Maximum postbaseline QTc (Bazett) and QTc (Fridericia) will also be tabulated by treatment 
group as follows:

Number (percentage) of subjects in greater than 450 msec, greater than 480 msec, and 
greater than 500 msec during the treatment, and

Number (percentage) of subjects with an increment of greater than 30 msec and greater 
than 60 msec from the baseline visit.
9.7.1.8.6
OTHER SAFETY ANALYSES
Other safety assessments including adolescent growth evaluations using 95th percentile CDC 
growth charts and bone age using x-ray of the hand, sexual maturation as measured in Tanner 
Staging, study drug effect on cognition assessed by Leiter-3, assessment of suicidality using 
C-SSRS, depression assessment using PHQ-9, will be summarized by treatment group at 
each scheduled visit.  In a subset of subjects, bone mineral density and content, total body fat 
mass, and total body lean mass using DEXA and their z-score will be summarized by 
treatment group at baseline and Week 52. For echocardiographic assessments, the proportion 
of subjects who develop FDA-defined valvulopathy, the proportion of subjects who develop 
pulmonary hypertension (defined as when a subject’s SPAP is ≥40 mmHg evaluated by 
echocardiograph], and change from baseline in SPAP will also be summarized by treatment 
group at Week 28 and Week 52. (revised per Amendments 01, 03, and 04)
9.7.2
Determination of Sample Size
The proposed sample size is based on the comparison of the primary efficacy endpoint, 
change from baseline in BMI at Week 52 between the Belviq XR 20-mg treatment group and 
placebo group.  Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 
260 subjects in a 1:1 ratio (n=130 in the Belviq XR 20-mg treatment group; n=130 in the 
placebo group) will have at least 80% power to detect a treatment difference of 1 kg/m2 in 
BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at 
least a 5% BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, 
this sample of 260 subjects (130 subjects for Belviq XR 20 mg and 130 subjects for placebo) 
will also have greater than 78% power to detect an absolute difference of 20% between the 
Belviq XR 20-mg group and placebo group, using a 2-sided Chi-Square test with α=0.05.  
The assumption used in the sample size calculation is based on the 2 pivotal lorcaserin 
studies, APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

11 PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE 
PROCEDURES)
11.1
Changes to the Protocol
Any change to the protocol requires a written protocol amendment or administrative change 
that must be approved by the sponsor before implementation.  Amendments specifically 
affecting the safety of subjects, the scope of the investigation, or the scientific quality of the 
study require submission to health or regulatory authorities as well as additional approval by 
the applicable IRBs/IECs.  These requirements should in no way prevent any immediate 
action from being taken by the investigator, or by the sponsor, in the interest of preserving 
the safety of all subjects included in the study.  If the investigator determines that an 
immediate change to or deviation from the protocol is necessary for safety reasons to 
eliminate an immediate hazard to the subjects, the sponsor’s medical monitor and the 
IRB/IEC for the site must be notified immediately.  The sponsor must notify the health or 
regulatory authority as required per local regulations.
Protocol amendments that affect only administrative aspects of the study may not require 
submission to health or regulatory authority or the IRB/IEC, but the health or regulatory 
authority and IRB/IEC should be kept informed of such changes as required by local 
regulations.  In these cases, the sponsor may be required to send a letter to the IRB/IEC and 
the Competent Authorities detailing such changes.
11.2
Adherence to the Protocol
The investigator will conduct the study in strict accordance with the protocol (refer to ICH 
E6, Section 4.5).
11.3
Monitoring Procedures
The sponsor’s/CRO’s CRA will maintain contact with the investigator and designated staff 
by telephone, letter, or email between study visits.  Monitoring visits to each site will be 
conducted by the assigned CRA as described in the monitoring plan.  The investigator will 
allow the CRA to inspect the clinical, laboratory, and pharmacy facilities to assure 
compliance with GCP and local regulatory requirements.  The CRFs and subject’s 
corresponding original medical records (source documents) are to be fully available for 
review by the sponsor’s representatives at regular intervals.  These reviews verify adherence 
to study protocol and data accuracy in accordance with local regulations.  All records at the 
site are subject to inspection by the local auditing agency and IRB/IEC review.

In accordance with ICH E6, Section 1.52, source documents include, but are not limited to 
the following:
•
Clinic, office, or hospital charts
•
Copies or transcribed health care provider notes which have been certified for accuracy 
after production
•
Recorded data from automated instruments such as IxRS, x-rays, and other imaging 
reports, (eg, sonograms, computerized tomography scans, magnetic resonance images, 
radioactive images, ECGs, rhythm strips, EEGs, polysomnographs, pulmonary function 
tests) regardless of how these images are stored, including microfiche and photographic 
negatives
•
Pain, quality of life, or medical history questionnaires completed by subjects
•
Records of telephone contacts
•
Diaries or evaluation checklists
•
Drug distribution and accountability logs maintained in pharmacies or by research 
personnel
•
Laboratory results and other laboratory test outputs (eg, urine pregnancy test result 
documentation and urine dip-sticks)
•
Correspondence regarding a study subject’s treatment between physicians or memoranda 
sent to the IRBs/IECs
•
CRF components (eg, questionnaires) that are completed directly by subjects and serve as 
their own source
11.4
Recording of Data
A CRF is required and must be completed for each subject by qualified and authorized 
personnel.  All data on the CRF must reflect the corresponding source document, except 
when a section of the CRF itself is used as source document.  Any correction to entries made 
on the CRF must be documented in a valid audit trail where the correction is dated, the 
individual making the correct is identified, the reason for the change is stated, and the 
original data are not obscured.  Only data required by the protocol for the purposes of the 
study should be collected.
The investigator must sign each CRF.  The investigator will report the CRFs to the sponsor 
and retain a copy of the CRFs.
11.5
Identification of Source Data
All data to be recorded on the CRF must reflect the corresponding source documents.

11.6
Retention of Records
The circumstances of completion or termination of the study notwithstanding, the 
investigator is responsible for retaining all study documents, including but not limited to the 
protocol, copies of CRFs, the Investigator's Brochure, and regulatory agency registration 
documents (eg, Form FDA 1572 ICFs, and IRB/IEC correspondence).  In addition, the 
sponsor will send a list of treatment codes by study subject to the investigator after the 
clinical database for this study has been locked.  The site should plan to retain study 
documents, as directed by the sponsor, for at least 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region or at least 3 years have elapsed since the formal 
discontinuation of clinical development of the investigational product.
It is requested that at the completion of the required retention period, or should the 
investigator retire or relocate, the investigator contact the sponsor, allowing the sponsor the 
option of permanently retaining the study records.
11.7
Auditing Procedures and Inspection
In addition to the routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of ICH GCP and all applicable local 
regulations.  If a government regulatory authority requests an inspection during the study or 
after its completion, the investigator must inform the sponsor immediately.
11.8
Handling of Study Drug
All study drugs will be supplied to the PI (or a designated pharmacist) by the sponsor.  Drug 
supplies must be kept in an appropriate secure area (eg, locked cabinet) and stored according 
to the conditions specified on the drug labels.  Investigational product will be stored in 
accordance with the DEA Regulations for Scheduled III - V Drugs and labeled storage 
conditions.  The investigator (or a designated pharmacist) must maintain an accurate record 
of the shipment and dispensing of the study drug in a drug accountability ledger, a copy of 
which must be given to the sponsor at the end of the study.  An accurate record of the date 
and amount of study drug dispensed to each subject must be available for inspection at any 
time.  The CRA will visit the site and review these documents along with all other study 
conduct documents at appropriate intervals once study drug has been received by the site.
All drug supplies are to be used only for this study and not for any other purpose.  The 
investigator (or site personnel) must not destroy any drug labels or any partly used or unused 
drug supply before approval to do so by the sponsor.  At the conclusion of the study and as 
appropriate during the study, the investigator (or a designated pharmacist) will return all used 
and unused drug containers, drug labels, and a copy of the completed drug disposition form 
to the sponsor’s CRA.

Appendix 2
Family-Based Lifestyle Program
Program Overview
All subjects and their caregivers (participating parent or guardian) in Study 403 will be 
encouraged to participate in a standardized weight management program for adolescents 
consisting of multicomponent behavior therapy.  The therapy will focus on healthy eating, 
physical activity, and lifestyle changes that will facilitate weight loss and weight loss 
maintenance. The role of the caregivers is to support their child or adolescents’ lifestyle 
changes and their taking of study medication.
The objectives of this program are as follows:

Develop a weight management program for all Belviq XR study participants and their 
caregivers (caregivers are instructed in methods to support their adolescents’ progress but 
caregivers are themselves not instructed to lose weight or take medication)

Standardize the weight management program across all study sites

Maximize participant retention

Promote participant’s adherence to both taking study medication and following the 
lifestyle program

days of PK sampling and the 
day before the subjects come to 
the clinic for PK sampling, 
study drug will be taken in the 
morning and doses recorded 2 
days prior to the clinic visit.

strategy
A single dose pharmacokinetic study 
in pediatric obese subjects (APD356-
A001-026) indicated that patients with 
body weight greater than or equal to 
60 kg can be administered a dose 
similar to that given to adults and 
adolescents.  Based on Centers for 
Disease Control and Prevention 
(CDC) growth chart data, almost all 
subjects over 9 years of age are likely 
to be at or over 60 kg body weight.  
Therefore, children age 9 to 11 years 
have been included in the current 
study.

Study Design
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in obese adolescents, 
ages 12 to 17 years.  Approximately 260 subjects will be randomized in a 1:1 ratio to Belviq XR 20 mg QD
(130 subjects) and placebo (130 subjects).  Subjects will be stratified by sex.  Subjects will receive Belviq XR
20 mg or matched placebo QD in a 1:1 ratio for up to 52 weeks. A recruitment plan will be developed to ensure 
at least 20% of younger subjects (12 to 13 years of age) are enrolled in the study.  Throughout the duration of 
the study, subjects will be encouraged to adhere to a lifestyle modification program that includes a 
standardized, age-appropriate diet and exercise counseling. (revised per Amendments 02 and 03)
The study will consist of 2 phases: Prerandomization and Randomization.  The Prerandomization Phase will 
last up to 30 days and consist of 1 visit during which subjects will be screened for eligibility.  The 
Randomization Phase consists of a Treatment Period and a Follow-Up Period.  The Treatment Period will last 
for a maximum of 52 weeks, with visits at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52.  The Follow-Up Period will 
extend from the End of Treatment (EOT) visit to the End of Study visit.
Subjects who screen fail can be re-screened only once after 30 days.  All subjects will continue in the study 
until the 52-week evaluation is completed.  Subjects who discontinue treatment prematurely will be followed up 
until study completion.  All attempts will be made to capture height and weight in all subjects whether or not 
they are still on study drug at the end of the study.  (revised per Amendment 03)
Study sites will be selected to ensure adequate representation of adolescents of ethnic and racial minorities.  
(revised per Amendment 03)
Data Monitoring Committee (revised per Amendment 03)
A Data Monitoring Committee (DMC) will be established to monitor and conduct periodic safety review of 
unblinded data. DMC members will be chosen based on their expertise in evaluating these clinical events. A 
separate DMC charter will be established.
Number of Subjects
Approximately 500 subjects will be screened to provide 260 randomized subjects.  (revised per Amendment 02)
Inclusion Criteria
1.
Healthy male or female adolescents, age 12 to 17 years (inclusive) at Screening, with an initial BMI that is 
greater than or equal to the United States (US)-weighted mean of the 95th percentile based on age and sex
with a body weight greater than 60 kg.  Subjects with T2DM may have a pre-existing or new diagnosis of

T2DM.
Subjects with pre-existing T2DM should have prior documentation consistent with the diagnosis and/or be 
on active pharmacotherapy for T2DM.  
Subjects with a new diagnosis of T2DM (ie, diagnosed at Screening) should be based on the 2016 
American Diabetes Association (ADA) guidelines.  The diagnostic criteria are met if a subject has 
unequivocal hyperglycemia (random plasma glucose ≥200 mg/dL (11.1 mmol/L) with classic symptoms of 
hyperglycemia or hyperglycemic crisis) OR any of the following criteria are observed and confirmed:
◦
HbA1c ≥6.5% 
◦
fasting plasma glucose (FPG) ≥126 mg/dL (7.0 mmol/L) 
◦
2-hour plasma glucose ≥200 mg/dL (11.1 mmol/L) by an oral glucose tolerance test (OGTT)
All T2DM subjects must have an HbA1c <10% at Screening.  If subjects are being or need to be treated 
with antidiabetic agents, the T2DM treatment regimen must be stable for at least 3 months before 
randomization.  A single rescreen is allowed following stabilization.  Stable control refers to minimal dose 
changes to existing medications for glycemic control and no medications being initiated for glycemic 
control in the 3 months before Randomization.  Minimal changes are defined as a change without any 
change in dose frequency, no add-on or discontinuation of other antidiabetic agents, and the subject has not 
been hospitalized due to hypo- or hyperglycemic events. (revised per Amendment 03)
2.
Subjects and their families not planning to move away from the area for the duration of the study
3.
Able and willing to comply with all aspects of the study, including a standardized, reduced-calorie diet and 
an age-appropriate, increased physical activity program
4.
Considered in stable health in the opinion of the investigator
5.
Caregivers or guardians meet the following requirements:
a.
Able and willing to support and supervise study participation in the opinion of the investigator,
including consideration of any existing physical, medical, or mental condition that prevents 
compliance with the protocol
b.
Able and willing to personally comply with and execute all aspects of the study requirements for the 
caregivers or guardians
Exclusion Criteria
1.
Clinically significant new illness within 1 month before randomization that may affect the subject’s ability 
to fulfill the study requirements or significantly confound the assessments
2.

4.
Any of the following findings on Screening echocardiography:

Aortic regurgitation mild or greater

Mitral regurgitation moderate or greater

Mitral or aortic valve stenosis greater than mild (ie, aortic stenosis [AS]: jet >3.0 m/s, mean gradient 
>25 mm Hg, and aortic valve area [AVA] <1.5 cm2; MS: mean gradient >5 mm Hg and mitral valve 
area [MVA] <1.5 cm2)

Systolic pulmonary artery pressure (SPAP) >40 mmHg (and/or tricuspid regurgitation (TR) jet 
velocity >2.9 m/s)
In cases where an actual SPAP value is not measurable due to lack of adequate TR jet, the pulmonary flow 
acceleration time measured at the right ventricular outflow tract (RVOTAT), will be used to assess 
eligibility. Patients with a RVOTAT ≤100 msec will be excluded, suggesting an elevated mean SPAP; 
eligibility for the those patients with RVOTAT between 100 and 120 msec will be determined based on 
combined assessment of the TR jet, septal motion and right ventricular size.


oral steroids (topical and inhaled steroids are acceptable)

stimulant medications (eg, Ritalin, Concerta, Biphetamine and Dexedrine)

benzodiazepines
The following concomitant medication guidelines/restrictions will apply:

Medications for the treatment of hypertension, dyslipidemia, or diabetes may be started, discontinued, or 
adjusted during the study according to local standards of care if, in the judgment of the investigator or the 
subject’s physician, such a change is medically indicated.

For diabetic subjects treated with sulfonylureas, insulin (note that subjects should not be enrolled as 
indicated in exclusion criteria), or other antidiabetic agents with hypoglycemic risk, the risk of 
hypoglycemic events may be higher if the subjects experience rapid and significant weight loss (more than 
10% weight reduction than at the previous visit).  It is recommended that the physician advise the subject 
to monitor their blood glucose more frequently and adjust their antidiabetic medications and diet 
accordingly. 

The antihyperglycemic medication dose would be considered for reduction in the event of 1 documented 
and otherwise unexplained hypoglycemic event (blood glucose concentration <65 mg/dL) or 2 
undocumented and otherwise unexplained suspected hypoglycemic events between any 2 scheduled visits. 
For subjects on more than 1 antihyperglycemic medication, it is recommended to reduce insulin first (if 
applicable), then the oral and/or other injectable antidiabetic agents.  If the previous criteria are met again 
following dose reduction, further dose reductions or cessation of 1 or more anti-hyperglycemic agents, are 
suggested.  See Section 9.5.4.2 for the definition and reporting of hypoglycemic events. 
To minimize the risk of cardiac valve toxicity, subjects must not initiate use of agents that have documented 
correlation with increased incidence of valvulopathy and/or pulumonary hypertension (eg, pergolide, 
ergotamine, methysergide, or cabergoline) during the study.  If any of the above agents are clinically warranted, 
and subjects initiate any of these agents, lorcaserin HCl should be discontinued but can be restarted on 
lorcaserin HCl after being off the medications above for 1 month.  Otherwise, the study medication should not 
be restarted, but the subject should continue all study visits.  (revised per Amendment 03)

primary efficacy endpoint regardless of whether or not the subject remained on study drug or completed other 
study assessments.  (revised per Amendment 03)
Pharmacokinetic Assessments
Blood samples (approximately 4 mL each) for PK assessment will be collected at Weeks 12, 28, 36, and 52 for 
analysis of Population PK. (revised per Amendment 01)
On the day of the Week 12, 28, and 52 clinic visits, subjects will be instructed not to take their study drug at 
home before the visit,but to bring their study drug to the clinic visit, and take their daily dose at the clinic.  
Two blood samples for determination of plasma concentrations of lorcaserin will be taken: 1 predose (within 
30 minutes before dosing), and 1 within 1 to 3 hours after dosing.  Dose times must be recorded for the last 
2 dosing times before the day of clinic visit. Week 52 PK samples should only be collected if the sample can be 
drawn within 60 hours of the last dose of study drug. (revised per Amendment 01)
On the day of the Week 36 clinic visit, subjects will take their study drug in the morning at home, and will be 
asked to visit the clinic within 4 to 6 hours of dosing that day, during which 1 blood sample for for PK
assessments will be collected. Dose times must be recorded for the last 2 dosing times prior to the clinic visit.

Pharmacogenomic/Pharmacogenetic Assessments
Not applicable
Safety Assessments
Safety assessments will consist of monitoring and recording all adverse events (AEs) and serious adverse events 
(SAEs); electrocardiograms (ECGs); laboratory evaluation for hematology, metabolic function (fasting glucose, 
fasting lipids, and thyroid), adrenal function and biochemical blood and urine bone health assessments; blood 
chemistry and urine values; neuropsychiatric events; periodic measurement of vital signs, neuromuscular signs
for screening potential serotonin syndrome, and signs or symptoms of priapism and hyperprolactinemia; and 
performance of physical examinations. In patients with potential prolactin-related AEs, such as galactorrhea,

changes in libido, or changes to menstrual cycle, fasting prolactin level will be measured and assessed.
Other Safety Assessments
Effect on growth will be evaluated using the CDC growth chart and bone age determination by x-ray of the 
hand. Sexual maturation will be evaluated by assessing sex hormones and Tanner Staging.   
The C-SSRS will be used to assess all subjects in the study for any signal of depression or suicidal ideation or 
behavior at every visit.  Additionally, screening, diagnosing, monitoring, and measuring the severity of 
depression will be assessed using the PHQ-9 and effects on cognition will be assessed using the Leiter-3.  
(revised per Amendment 01)
Bone mineral density and content, total body fat mass and total body lean mass will be determined using DEXA 
in a subset of randomized subjects (selected prior to randomization) at selected sites.  (revised per Amendment 
03)
Echocardiographic assessments will be used to exclude subjects with FDA-defined valvulopathy, pulmonary 
hypertension, and other major cardiovascular disease (as outlined in Exclusion Criterion No. 3) during the 
Screening Period.  Additionally, cardiac valvular function and pulmonary systolic pressure changes at Weeks
28 and 52 will be assessed only for subjects at selected sites.
Valvular regurgitation as assessed in the 
echocardiogram will be rated absent, trace, mild, moderate, or severe for the aortic, mitral, and tricuspid valves; 
the rating will be absent or present for the pulmonic valve. The evaluations will be based on guidelines from the 
American Society of Echocardiography. Pulmonary artery pressure will be estimated from the TR jet velocity.  
(revised per Amendment 03)
Bioanalytical Methods
Lorcaserin will be quantified in plasma using a validated liquid chromatography coupled with tandem mass 
spectrometry.

Analysis Sets

The Safety Analysis Set is the group of subjects who received at least 1 dose of study drug and had at least 
1 post dose safety assessment.

The Full Analysis Set (FAS) is the group of all randomized subjects regardless of adherence to study drug.

Per-Protocol Analysis Set (PP) is the group of all randomized subjects who are 80% or greater compliant 
with study medication, completed the study, have no major protocol deviations, have no violations of 
inclusion or exclusion criteria, and have BMI data at Baseline and Week 52.  The determination of subjects 
to be excluded from this population based on the above criteria and a list of major protocol violations will 
be included in the statistical analysis plan (SAP) and finalized before data base lock.

The PD Analysis Set is the group of subjects who had sufficient PD data to derive at least 1 PD parameter.

The PK Analysis Set is the group of all randomized subjects from whom at least 1 valid lorcaserin plasma 
concentration was obtained with associated documented dosing history.

The population PK/PD set is the group of randomized subjects with PK information and who have at least 
1 adequately documented measurement of BMI.
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, and the PP will be used as a 
supportive analysis.  Unless otherwise specified, a 2-sided α=0.05 significance level will be used in all efficacy 
analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change from baseline in 
BMI will be analyzed using analysis of covariance model (ANCOVA) with factors of treatment,  sex (male and 
female) as fixed effect, and the baseline age and BMI as covariates.  The missing values will be imputed using a 
pattern mixture model utilizing multiple imputation (MI) assuming the missing values are missing not at 
random (MNAR).  The missing values will be imputed at each visit using all available values including the 
retrieved measurement from the postdiscontinuation data.  The details of the analysis model and missing value 
imputation method will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis:  The same primary efficacy analyses described above will be repeated based on the PP.

Change from baseline in standardized BMI score (Z-score):  The same primary efficacy analyses described 
above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed and will be
described in the SAP.
Key Secondary Efficacy Analyses
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 5% BMI reduction at 
Page 123 of 897

Clinical Study Protocol
APD356-A001-403
Eisai
FINAL:  v9.0, 12Dec2017

Page 11 of 84
Week 52. The secondary efficacy endpoint will be analyzed only if the test for the primary efficacy endpoint is 
statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be analyzed using a logistic 
regression model with factors of treatment, sex (male and female), and baseline BMI as a covariate using FAS.  
Subjects with any missing assessment at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be analyzed using 
mixed effect model repeated measurement analysis (MMRM) and categorical variables will be analyzed using
the Cochran Mantel Haenszel test, Chi-square test, or logistic regression as appropriate.  Additional analysis 
may be performed as needed using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male and female), and 
race (American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or other Pacific 
Islander, or White) and age.  Additional subgroups may be explored, if deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and sensitivity analyses.
Pharmacokinetic Analyses
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using nonlinear mixed 
effects modeling. The effect of covariates such as baseline characteristics or demographics on PK will be 
explored. Derived exposure parameters such as the maximum observed concentration and the area under the 
concentration-time curve from time 0 to 24 hours at steady-state will be calculated from the final PK model 
using individual posterior estimates of the PK parameters and from dosing history. The PK analysis set will be 
used for this analysis.
Pharmacodynamic Analyses
Change from Baseline in BMI will be assessed as the PD endpoint.  The PD analysis set will be used for this 
analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% and ≥10% BMI 
reduction, and change in waist circumference from baseline) will also be assessed as part of the PD analysis.  
The PK/PD analysis set will be used for this analysis.
Pharmacokinetic/Pharmacodynamic Analyses
Population PK/PD modeling will be used to explore the relationship between lorcaserin plasma exposure and 
response, including but not limited to change in BMI from baseline and the probability of achieving at least a 
5% and at least a 10% change in BMI from baseline to Week 52.  Additionally, exposure-safety relationships 
for select safety parameters may be explored graphically depending on the data at the end of study.  Any 
emergent relationship may be modeled as appropriate.  Any parameters based on the study data may be 
considered for exploratory assessment for its relationship to PK.
Pharmacogenomic/Pharmacogenetic Analyses
Not applicable
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments including the incidence 
of AEs (including changes from baseline in physical examination), growth (CDC growth chart and bone age 
determined by x-ray of the hand), sexual maturation (Tanner Staging), out-of-normal-range laboratory safety 
test values, change from baseline in laboratory safety test values, ECGs, and vital sign measurements will be 
summarized by treatment group using descriptive statistics or frequency count as appropriate.  
Other Safety Analyses
In addition, cognition will be evaluated by the Leiter-3, depression will be evaluated by the PHQ-9, and suicidal 
ideation and behavior will be evaluated by the C-SSRS, and will also be summarized by treatment group using 
descriptive statistics or frequency count as appropriate. For echocardiographic assessments, the proportion of 
subjects who develop FDA-defined valvulopathy, the proportion of subjects who develop pulmonary

hypertension [pulmonary hypertension is defined when the subject’s systolic pulmonary artery pressure 
(SPAP) ≥40 mmHg evaluated by echocardiograph], and change from baseline in SPAP will be summarized by 
treatment group at Week 28 and Week 52 using descriptive statistics or frequency count as appropriate. (revised 
per Amendment 01)
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
Interim Analyses

Sample Size Rationale
The proposed sample size is based on the comparison of the primary efficacy endpoint, change in BMI from 
Baseline to Week 52 between the Belviq XR 20-mg treatment group and placebo group.  Assuming a SD of 
2.2 kg/m2 and a 40% dropout rate, a sample size of 260 subjects in a 1:1 ratio (n=130 in the Belviq XR 20-mg 
treatment group; n=130 in the placebo group) will have at least 80% power to detect a treatment difference of 
1 kg/m2 in BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at least a 5% 
BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, this sample of 260 subjects 
(130 subjects for Belviq XR 20 mg and 130 subjects for placebo) will also have greater than 78% power to 
detect an absolute difference of 20% between the Belviq XR 20-mg group and the placebo group, using a 
2-sided Chi-Square test with α=0.05.
The assumption used in the sample size calculation is based on the 
2 pivotal lorcaserin studies APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

ETHICS
5.1
Institutional Review Boards/Independent Ethics Committees
The protocol, Informed Consent Form (ICF), and appropriate related documents must be 
reviewed and approved by an Institutional Review Board (IRB) or Independent Ethics 
Committee (IEC) constituted and functioning in accordance with International Conference on 
Harmonisation (ICH) Good Clinical Practice (ICH E6), Section 3, and any local regulations 
(eg, Federal Regulations, Title 21 Code of Federal Regulations [21 CFR] Part 56).  Any 
protocol amendment or revision to the ICF will be resubmitted to the IRB/IEC for review and 
approval, except for changes involving only logistical or administrative aspects of the study 
(eg, change in clinical research associate [CRA], change of telephone number[s]).  
Documentation of IRB/IEC compliance with the ICH E6 and any local regulations regarding 
constitution and review conduct will be provided to the sponsor.
A signed letter of study approval from the IRB/IEC chairman must be sent to the principal 
investigator (PI) with a copy to the sponsor before study start and the release of any study 
drug to the site by the sponsor or its designee (ICH E6, Section 4.4).  If the IRB/IEC decides 
to suspend or terminate the study, the investigator will immediately send the notice of study 
suspension or termination by the IRB/IEC to the sponsor.
Study progress is to be reported to IRB/IECs annually (or as required) by the investigator or 
sponsor, depending on local regulatory obligations.  If the investigator is required to report to

INTRODUCTION
7.1
Indication
Obesity has become a global epidemic, causing a serious public health concern.  In the 
United States, the prevalence of obesity in adolescents ages 12 and 19 years has almost 
doubled over the past 2 decades.  The rate increased from 10.5% between 1988 and 1994 to 
20.5% between 2011 and 2012 (CDC/NCHS, 2013).  Obesity in adolescents, defined in the 
United States as greater than or equal to the 95th percentile in gender- and age-specific body 
mass index (BMI), continues to grow at an alarming rate in the United States and globally.  
Based on data (Wang and Lobstein, 2006) using various criteria for the definition of obesity 
that included more than 30 countries in Europe, North America, Asia, and the West Pacific, 
prevalence of obesity in these countries has also increased significantly, at a rate comparable 
to that in the United States.
Adolescent obesity has many negative implications for both the health and well-being of the 
individual as well as for society.  These include increased susceptibility to a host of diseases, 
chronic health disorders, psychological disorders, and premature death (Flegal, et al., 2005; 
Rofey, et al., 2009).  Increases in the prevalence of overweight and obese adolescents may 
result in a decrease in life expectancy for the 1st time in 200 years (Peeters, et al., 2003).
As a result, there is a significant impact on the cost of healthcare.  It is estimated that medical 
costs due to overweight adolescents are approximately $14 billion per year in the United 
States (Trasande and Chatterjee, 2009).  Obesity-related medical costs in general are
expected to rise significantly because today’s obese adolescents are likely to become 
tomorrow’s obese adults (Whitaker, et al., 1997).
Current approaches to weight management in adults include lifestyle modification, 
pharmacotherapy, and invasive bariatric procedures.  Lifestyle modification involves a 
combination of diet, exercise, and behavioral change, and is the preferred and essential 
strategy for weight management in obese and overweight individuals, including adolescents.  
Although lifestyle modification can be very efficacious in some patients, adherence to the 
prescribed regimens is often poor.  As such, lifestyle modification alone is often not adequate 
and the weight loss is often transient.  On the other hand, bariatric surgery and various other 
invasive procedures are generally reserved for the severely obese population. 
Pharmacotherapy can play a significant role in weight management programs, and is often 
combined with lifestyle modification to enhance weight loss beyond that which is normally 
achieved with diet and exercise alone.  Current pharmacotherapies offer the potential to 
significantly augment weight loss when combined with diet and exercise, but are rarely used 
for adolescents.
The current standard of care for treatment of obesity in adolescent subjects ranges from
behavioral therapy including lifestyle intervention to the rare use of pharmacotherapy in 
adolescents over 12 years of age (McGovern, et al, 2008; Spear, et al, 2007).  Xenical®
(orlistat) is currently the only product available for weight control in obese adolescent 
patients 12 to 16 years of age.  However, it is associated with gastrointestinal side effects

(Xenical PI. 2015), and the treatment effect of Xenical is modest. In a study that included 
539 obese adolescents with BMI above the 97th percentile, Xenical demonstrated a 0.86 BMI 
reduction relative to placebo after 52 weeks of treatment (-0.55 BMI in the Xenical treatment 
group versus +0.31 BMI in the placebo group) (FDA, 2003; Chanoine, et al, 2005).
Obtaining maximum retention in the study is a major goal in order to minimize missing data.  
A number of strategies have been used in prior adolescent weight loss studies may be used in 
the present study to help retain participants.  These include a highly trained and competent 
site staff, ample waiting area, readily available parking (at no cost), access to mass transit, 
and reminder and follow-up calls.  In addition, sites may utilize fun and interactive group 
sessions with games and hands-on nutrition and physical activity demonstrations, random 
raffle drawings, social events, birthday and holiday cards, and newsletters to further 
encourage subject retention.  Furthermore, we may make home visits for primary efficacy 
assessments, as needed, to maximize data collection. 
By incorporating some of these 
retention strategies, we hope that we will maximize participant retention, which will help us 
cope with missing data.
7.1.1
APD356/Belviq (lorcaserin hydrochloride)
7.1.1.1
Mechanism of Action
Belviq is a selective serotonin 2c receptor agonist which was approved by the US Food and 
Drug Administration (FDA) on 27 Jun 2012 as an adjunct to a reduced-calorie diet and 
increased physical activity for chronic weight management in adult patients with a BMI of at 
least 30 kg/m2 (obese), or adult patients with a BMI greater than or equal to 27 kg/m2
(overweight) in the presence of at least 1 weight-related comorbid condition.
7.1.1.2
Clinical Experience with APD356/Belviq (lorcaserin hydrochloride)
The Phase 3 clinical evaluation of Belviq in studies of more than 7700 adult subjects, 
including 604 subjects with Type 2 diabetes mellitus, demonstrated clinically meaningful 
efficacy and a safety profile that includes minimal and easily managed risks.  In each of the 
individual studies and in the pooled efficacy analyses, the Belviq dose met the following 
prespecified endpoints:

A significantly greater proportion of adult subjects taking Belviq 10 mg twice per day 
(BID) (47%) lost at least 5% of baseline body weight at 52 weeks as compared to 
subjects taking placebo (23%).  A significantly greater proportion of subjects taking 
Belviq 10 mg BID (22.4%) lost at least 10% of baseline body weight at 1 year as 
compared to subjects taking placebo (8.7%). 

The mean weight loss at 1 year in adult subjects taking Belviq 10 mg BID (-5.8 kg) was 
significantly greater than that in subjects taking placebo (-2.5 kg).
An integrated evaluation of the data from the pediatric, adolescent, and adult subjects 
revealed that the relationship between lorcaserin area under the curve (AUC) and body 
weight in pediatric and adult subjects is consistent irrespective of the individual studies or 
age range of the study population. Irrespective of age, lorcaserin AUC values in the pediatric 
subjects with body weight of greater than 60 kg overlapped with the data observed from the

studies involving adult subjects, suggesting a fixed dose approach similar to adults can be 
used for adolescent subjects with body weight greater than 60 kg.
In adolescent obese populations, it is anticipated that Belviq XR will result in similar effects.
As part of FDA postmarketing requirements, this study is designed to characterize the 
efficacy and safety of Belviq XR in adolescent obese populations in the United States.  It is 
also intended to support an indication for chronic weight management for obese adolescents 
ages 12 to 17 years old. 
7.1.2
Study Rationale
There is no specific FDA guidance for the approval of a weight loss product for adolescents.  
In adults, the Division’s 2007 draft Guidance for Industry Developing Products for Weight 
Management indicate that the product needs to satisfy either of the following mean or 
categorical criteria after 1 year of treatment:

The difference in mean weight loss between the active-product and placebo-treated 
groups is at least 5% and the difference is statistically significant.

The proportion of subjects who lose at least 5% of baseline body weight in the 
active-product group is at least 35%, is approximately double the proportion of subjects 
in the placebo-treated group who lose at least 5% of baseline body weight, and the 
difference between groups is statistically significant.
FDA awarded a weight management indication for Belviq based on Phase 3 study results 
which achieved the categorical criteria. In a Phase 3 study, a significantly greater proportion 
of subjects taking Belviq (47%) lost at least 5% of baseline body weight at 1 year as 
compared to subjects taking a placebo (23%).  It is anticipated that a similar effect will be 
demonstrated in obese adolescents, where weight loss will be assessed using BMI
measurements to account for growth. In this study, the objective is to demonstrate that BMI
reduction will be achieved during 52 weeks of treatment with Belviq XR 20 mg administered 
once daily (QD) compared to placebo in obese adolescents.
In the Phase 3 orlistat study in obese adolescents mentioned above, the proportion of subjects 
who lost at least 5% body weight is relatively low. At the end of the study at Week 52, only 
26.5% of the subjects achieved a 5% or greater BMI reduction compared to 15.7% in the 
placebo group. The placebo-corrected BMI reduction was about 0.86 kg/m2.  
There are limited trials for weight reduction in the adolescent population, ages 12 to 17 years
(Peirson, et al, 2015).  Thirty-one studies (29 behavioral, 2 pharmacological and behavioral) 
were included in a meta-analysis of randomized studies conducted in primary care centers in 
overweight and obese children and youth ages 2 to 18 years using behavioral (diet, exercise,
and lifestyle) and pharmacological interventions and providing 6-month postbaseline BMI or 
prevalence of overweight or obesity. Both interventions showed a significant effect on BMI 
in favor of treatment (behavioral: 
standardized mean difference [SMD] -0.54, 
95% confidence interval [CI]
-0.73, -0.36; orlistat plus behavioral: 
SMD -0.43, 
95% CI -0.60, -0.25). The studies reported no significant difference between groups in the 
likelihood of reduced prevalence of overweight or overweight and obese. A great deal of

variation was noted across efficacious interventions.
In conclusion, this meta-analysis 
demonstrated low-quality evidence that behavioral treatments alone are associated with a 
smaller effect in terms of reduced BMI compared with the effect shown by combined 
behavioral and pharmacological interventions. This may be because the effect size in the 
randomized, double blind, placebo controlled, phase 3 orlistat study in adolescents was 
relatively low and there was a lack of maintenance effect. These subjects started to regain 
their BMI after 6 months of treatment. At end of the study, only 26.5% of subjects achieved 
a 5% or greater BMI reduction compared to 15.7% in placebo group. In a sibutramine 
Phase 3 study in obese adolescents, a substantially higher proportion of subjects (69%) 
treated with sibutramine achieved at least a 5% BMI reduction compared to 21% of subjects 
in the placebo group. In addition, sibutramine resulted in a substantial reduction in mean 
BMI (between-group difference, 2.9 kg/m2) and mean weight (between-group difference, 
8.4 kg) compared to placebo (Berkowitz, et al, 2006).  Unlike the weight loss effect of Belviq
in adults and sibutramine in adolescents, subjects in the orlistat study started to increase their 
BMI after 6 months of treatment.
In this study, it is assumed that treatment with Belviq XR 20 mg will lead to a BMI reduction
of more than 1 kg/m2, and a higher proportion of subjects will achieve more than a 5% and 
10% BMI reduction compared to placebo.  A between-group difference of 24% is the basis 
for the conservative assumption of a 20% effect size in the current study.
In addition, the total sample size of 260 subjects will be adequate to assess safety and 
exposure based on previous adolescent studies with weight management products (orlistat 
sibutramine, and liraglutide 3 mg) (FDA, 2003; Chanoine, et al., 2005; Berkowitz, et al,
2006; CT.gov NCT02918279) and other metabolic or dyslipidemia medication products
(ezetimibe, simvastatin) (FDA, 2007).  (revised per Amendment 02)

INVESTIGATIONAL PLAN
9.1
Overall Study Design and Plan
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in 
obese adolescents ages 12 to 17 years.  Approximately 260 subjects will be randomized in a 
1:1 ratio to Belviq XR 20 mg QD (130 subjects) and placebo (130 subjects).  Subjects will be 
stratified by sex.  Subjects will receive Belviq XR 20 mg or matched placebo QD in a 1:1 
ratio for up to 52 weeks. A recruitment plan will be developled to ensure at least 20% of 
younger subjects (12 to 13 years of age) are enrolled in the study.  Throughout the duration 
of the study, subjects will be encouraged to adhere to a lifestyle modification program that 
includes a standardized, age-appropriate diet and exercise counseling (see Appendix 2).  
(revised per Amendments 02 and 03)
The study will consist of 2 phases:
Prerandomization and Randomization.  The 
Prerandomization Phase will last up to 30 days and consists of 1 visit during which subjects 
will be screened for eligibility.  The Randomization Phase consists of a Treatment Period and 
a Follow-Up Period.  The Treatment Period will last for a maximum of 52 weeks, with visits 
at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52; the Follow-Up Period will extend from the 
End of Treatment (EOT) visit to the End of Study (EOS) visit.
Subjects who screen fail can be rescreened only once after 30 days.  All subjects will 
continue in the study until the 52-week evaluation is completed.  Subjects who discontinue 
treatment prematurely will be followed up until study completion.  All attempts will be made 
to capture height and weight in all subjects whether or not they are still on study drug at the 
end of the study.  (revised per Amendment 03)
Study sites will be selected to ensure adequate representation of adolescents of ethinic and 
racial minorities.  (revised per Amendment 03)
A Data Monitoring Committee (DMC) will be established to monitor and conduct periodic 
safety review of unblinded data. DMC members will be chosen based on their expertise in 
evaluating these clinical events. A separate DMC charter will be established.  (revised per 
Amendment 03)
9.1.1
Prerandomization Phase
Screening will occur during the Prerandomization Phase at Visit 1.
9.1.1.1
Screening Period
The purpose of the Screening Period is to obtain the informed consent and assent and to 
establish protocol eligibility.  Procedures to be followed when obtaining informed consent 
are detailed in Section 5.3.  Careful initial screening is important in the recruitment of 
families who both fully understand the requirements of this 1 year, randomized, controlled 
trial and are truly interested in participation.  Interested caregivers and adolescents will be 
screened by phone to assess preliminary entry criteria.  Candidates will be given a brief

description of the program and general study requirements, with an adolescent and a 
caregiver who is willing to participate.  If preliminary entry criteria are met, adolescents and 
their caregivers will be invited to an initial in-clinic meeting to further discuss the study.  A 
complete description of the study including assessments, the number of visits, the lifestyle 
program, the fact that the adolescent would be taking either the study drug or a placebo, the
duration of the study, and the necessity of having an adolescent wishing to participate as well 
as a participating caregiver will be described.  Consent and assent will be obtained and copies 
of the signed forms will be provided to families.  The importance of the study and its 
scientific merit will be discussed.  Ineligible adolescents will be referred to local weight 
management resources.  Screening period assessments and timing thereof are shown in 
Section 9.5.2.
9.1.2
Randomization Phase
The Randomization Phase will consist of 2 periods: the Treatment Period and the Follow-Up 
Period. The Treatment Period assessments and timing thereof are shown in Section 9.5.2.

Discussion of Study Design, Including Choice of Control Groups
The proposed dose and dosing frequency of Belviq XR in this study is 20 mg QD.  The PK 
parameters of a single 10-mg dose of Belviq were evaluated in healthy, adolescent obese 
subjects in Study APD356-025.  Overall, the PK parameters of Belviq and its main 
metabolites, M1 and M5, were similar to those in adults.  Following a single, oral 
administration of Belviq 10 mg to a total of 8 healthy adolescent (ages 12 to 17 years old) 
obese subjects, the mean maximum concentration observed and the area under the 
concentration-time curve from time zero to infinity (AUC(0-inf)) were 36.5 ng/mL and 
464 hr×ng/mL, respectively.  The mean Belviq terminal phase half-life was 9.70 hours, 
similar to that observed in adults, thus supporting a similar dosing frequency (QD) in 
adolescent subjects.
Additionally, a single dose PK study in 8 healthy obese pediatric subjects ages 6 to 11 years 
of age was performed. The PK analysis after a single 10-mg dose of lorcaserin revealed that 
the lorcaserin AUC(0-inf) values tended to increase with decreasing body weight and age.
However, the body weight normalized AUC(0-inf) values were similar across the age groups, 
therefore the data indicated no effect of age on the lorcaserin PK. Integrated assessment of 
the PK versus body weight relationship, pooling the data from pediatric and adult subjects 
from previous studies, suggested that the lorcaserin area under the curve values for subjects 
with body weight of at least 60 kg overlapped with the area under the curve values from 
adolescents and adults. Therefore, no dose adjustment relative to adults and adolescents is 
deemed necessary for pediatric or adolescent subjects with a body weight of at least 60 kg.
Based on CDC growth charts, the likelihood of subjects who are older than 12 years of age 
having a body weight of less than 60 kg is very low; therefore, the current study as designed

to enroll subjects between 12 to 17 years of age with body weight at least 60 kg, will cover
majority of the population of interest.  The targeted study population comprises 260 obese 
adolescents 12 to 17 years of age, with a body weight at least 60 kg.  (revised per 
Amendment 02)
Obese adolescents will be identified using gender- and age-specific BMI measurement.  
Obesity in adolescents is defined by US Expert committee recommendations as BMI in or 
above the 95th percentile (Barlow, 2007).
Randomization will be used in this study to avoid bias in the assignment of subjects to 
treatment, to increase the likelihood that known and unknown subject attributes 
(eg, demographics, baseline characteristics) are balanced across treatment groups, and to 
ensure the validity of statistical comparisons across treatment groups.  Blinding to treatment 
will be used to reduce potential bias during data collection and evaluation of endpoints.
9.3
Selection of Study Population
Approximately 500 subjects will be screened to ensure that 260 subjects will be randomized.  
(revised per Amendment 02)
Subjects who do not meet all inclusion criteria or do meet any exclusion criteria will not be 
eligible to receive study drug.
Subjects who screen fail can be re-screened immediately 
without repeating the screening echocardiogram for up to 90 days after the previous 
echocardiogram.  All other screening assessments must be repeated when a subject is re-
screened.  Subjects that re-screen more than 90 days after the previous echocardiogram must 
repeat all screening assessments including the screening echocardiogram.  (revised per 
Amendment 03)
9.3.1
Inclusion Criteria
Subjects must meet all of the following criteria to be included in this study:
1. Healthy male or female adolescents, ages 12 to 17 years old (inclusive) at Screening, with 
an initial BMI that is greater than or equal to the United States (US)-weighted mean of 
the 95th percentile based on age and sex with a body weight greater than 60 kg.  Subjects 
with T2DM may have a pre-existing or new diagnosis of T2DM.  
Subjects with pre-existing T2DM should have prior documentation consistent with the 
diagnosis and/or be on active pharmacotherapy for T2DM.  
Subjects with a new diagnosis of T2DM (ie, diagnosed at Screening) should be based on 
the 2016 American Diabetes Association (ADA) guidelines.  The diagnostic criteria are 
met if a subject has unequivocal hyperglycemia (random plasma glucose ≥200 mg/dL 
(11.1 mmol/L) with classic symptoms of hyperglycemia or hyperglycemic crisis) OR any 
of the following criteria are observed and then confirmed:
o
HbA1c ≥6.5% 
o
fasting plasma glucose (FPG) ≥126 mg/dL (7.0 mmol/L)

o
2-hour plasma glucose ≥200 mg/dL (11.1 mmol/L) by an oral glucose tolerance 
test (OGTT)
All T2DM subjects must have an HbA1c <10% at Screening.  If subjects are being or 
need to be treated with antidiabetic agents, the T2DM treatment regimen must be stable 
for at least 3 months before randomization.  A single rescreen is allowed following 
stabilization.  Stable control refers to minimal dose changes to existing medications for 
glycemic control and no medications being initiated for glycemic control in the 3 months 
before Randomization.  Minimal changes are defined as a change without any change in 
dose frequency, no add-on or discontinuation of other antidiabetic agents, and the subject 
has not been hospitalized due to hypo- or hyperglycemic events.  (revised per 
Amendment 03)

All packaging and labeling will be performed according to Good Manufacturing Practices 
and GCP guidelines.
Study drug must be stored as instructed on the study drug label and in accordance with the
DEA Regulations for Schedule IV Controlled Drugs (US sites). Study drug must be kept
in a secure location as required by DEA regulations and carefully stored at the study site
within its original container.
The investigator (or pharmacist, as appropriate) must maintain records of the delivery of
the study drug to the study site, the inventory at the site, use for each subject, and return of
the study drug to a delegate of the sponsor. Total study site accountability will be conducted
at the end of the study and the investigator must explain any discrepancies.
A Drug Dispensing Log must be kept current and should contain at least the following 
information:

Identification (subject ID number and initials) of the subject to whom the study drug was 
dispensed
•
The dates and unique kit or carton identifiers for dispensed study drug
•
Initial inventory on receipt of drug at the site
•
Final inventory on completion of the study
All records and inventory must be available for inspection by the clinical study
monitor.
9.4.2.4
Storage Conditions
Where applicable, investigational product will be stored in accordance with the DEA 
Regulations for Scheduled III to V Drugs and labeled storage conditions.  Temperature 
monitoring is required at the storage location to ensure that the study drug is maintained 
within an established temperature range.  The investigator or designee is responsible for 
ensuring that the temperature is monitored throughout the total duration of the study and that 
records are maintained; the temperature should be monitored continuously by using either an 
in-house validated data acquisition system, a mechanical recording device, such as a 
calibrated chart recorder, or by manual means, such that minimum and maximum 
thermometric values over a specific time period can be recorded and retrieved as required.
9.4.3
Method of Assigning Subjects to Treatment Groups
Subjects will be assigned to treatments based on a computer-generated randomization 
scheme that will be reviewed and approved by an independent statistician.  The 
randomization scheme and identification for each subject will be included in the final clinical 
study report for this study.
Subjects will be centrally stratified by sex (male and female).  Within each stratum, subjects 
will be randomized to receive either Belviq XR 20 mg or placebo QD in a 1:1 ratio.

Randomization will be performed centrally by an interactive voice or web response system 
(IxRS).  The IxRS or clinical supply vendor will generate the randomized identification
numbers to be included on study packaging.  Upon signature of the ICF, the investigator or 
designee will access the IxRS to register the subject information.  At Randomization, the 
IxRS will assign each subject a unique randomization number.  At each subsequent visit 
during the Treatment Period and Follow-Up Period, the investigator or designee will access 
IxRS to obtain dispensing information and to register the subject’s visit.
9.4.4
Selection and Timing of Dose for Each Subject
Subjects should take the study medication once daily at approximately the same time of 
every day, and be encouraged to take the study medication with an adequate amount of water 
(8 oz. or 240 mL).  For information on dosing on visits associated with PK sampling, see 
Section 9.5.1.4.1.  (revised per Amendment 03)
9.4.5
Blinding
During the Randomization Phase, subjects and all personnel involved with the conduct and 
interpretation of the study, including investigators, site personnel, and sponsor staff will be 
blinded to the treatment codes.  Randomization data will be kept strictly confidential, filed 
securely by an appropriate group with the sponsor or CRO, and accessible only to authorized 
persons (eg, Eisai Global Safety) until the time of unblinding, per the SOP.
A master list of all treatments and the subject numbers associated with them will be 
maintained in a sealed envelope by the clinical supply vendor, the IxRS vendor, and the 
sponsor.  In the event that emergency conditions require knowledge of the study treatment 
given, the blind may be broken via the code breaker facility within the IxRS.  Emergency 
procedures for revealing drug codes are given in Section 9.5.4.5.  If possible, before breaking 
the blind, the investigator should consult with the sponsor or designee to ascertain the 
necessity of breaking the code.
9.4.6
Prior and Concomitant Therapy
Any medication (including OTC medications) or therapy administered to the subject during 
the study (starting at the date of informed consent) will be recorded on the Prior and
Concomitant Medication Case Report Form (CRF) or Non-Pharmacological Procedures 
CRF.  The investigator will record on the Adverse Event CRF any AE for which the 
concomitant medication/therapy was administered. If the concomitant medication/therapy is 
being administered for a medical condition present at the time of entry into the study, the 
investigator will record the medical condition on the Medical History and Current Medical 
Condition CRF.

The following concomitant medication guidelines/restrictions will apply:

Medications for the treatment of hypertension, dyslipidemia, or diabetes may be 
started, discontinued, or adjusted during the study according to local standards of care 
if, in the judgment of the investigator or the subject’s physician, such a change is 
medically indicated.

For diabetic subjects treated with sulfonylureas, insulin (note that subjects should not 
be enrolled as indicated in exclusion criteria), or other antidiabetic agents with 
hypoglycemic risk, the risk of hypoglycemic events may be higher if the subjects 
experience rapid and significant weight loss (more than 10% weight reduction than at 
the previous visit).  It is recommended that the physician advise the subject to 
monitor their blood glucose more frequently and adjust their antidiabetic medications
and diet accordingly.


The antihyperglycemic medication dose would be considered for reduction in the 
event of 1 documented and otherwise unexplained hypoglycemic event (blood 
glucose concentration <65 mg/dL) or 2 undocumented and otherwise unexplained 
suspected hypoglycemic events between any 2 scheduled visits.   For subjects on 
more than 1 antihyperglycemic medication, it is recommended to reduce insulin first 
(if applicable), then the oral and/or other injectable antidiabetic agents.  If the 
previous criteria are met again following dose reduction, further dose reductions or 
cessation of 1 or more anti-hyperglycemic agents, are suggested.  See Section 9.5.4.2
for the definition and reporting of hypoglycemic events. 
To minimize the risk of cardiac valve toxicity, subjects must not initiate use of agents that 
have documented correlation with increased incidence of valvulopathy and/or PH (eg, 
pergolide, ergotamine, methysergide, or cabergoline) during the study.  (revised per 
Amendment 01)  If any of the above agents are clinically warranted, and subjects initiate any 
of these agents, lorcaserin HCl should be discontinued but can be restarted on lorcaserin HCl 
after being off the medications above for 1 month.  Otherwise, the study medication should 
not be restarted, but the subject should continue all study visits.  (revised per Amendment 03)
9.4.7
Treatment Compliance
Records of treatment compliance for each subject will be kept during the study.  Subjects will 
be asked to bring their study drug bottles to each visit.  The CRAs will review treatment 
compliance during site visits and at the completion of the study.  (revised per 
Amendment 03)
Per visit schedule, subjects will return unused study drug and be given a new supply; pill 
counts will be made by study staff on returned medication.

9.5.1.5.1
ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered an investigational product.  An AE does not necessarily have a causal

relationship with the medicinal product.  For this study, the study drug is Belviq XR
(lorcaserin hydrochloride).
The criteria for identifying AEs in this study are:
•
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or 
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE)
•
Any new disease or exacerbation of an existing disease 
•
Any deterioration in non-protocol-required measurements of a laboratory value or other 
clinical test (eg, ECG, x-ray) that results in symptoms, a change in treatment, or 
discontinuation of study drug
•
Recurrence of an intermittent medical condition (eg, headache) not present pretreatment 
(Baseline)
•
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of study drug, or withholding 
of study drug, whether prescribed in the protocol or not.
All AEs observed during the study will be reported on the Adverse Event CRF.  All AEs,
regardless of relationship to study drug or procedure, should be collected beginning from the 
time the subject signs the study ICF through the last visit in the Treatment Phase.  Subjects 
who fail screening primarily due to AE(s) must have the AE(s) leading to screen failure 
reported on the Screening Disposition CRF.  SAEs will be collected for 28 days after the last 
dose.
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute 
an AE.  Medical and scientific judgment should be exercised in deciding whether an isolated 
laboratory abnormality should be classified as an AE.  Any laboratory abnormality 
considered to constitute an AE should be reported on the Adverse Event CRF. 
Abnormal ECG (corrected QT interval [QTc]) results, if not otherwise considered part of a 
clinical symptom that is being reported as an AE, should be considered an AE if the QTc 
interval is greater than 450 msec and there is an increase of more than 60 msec from baseline.  
Any ECG abnormality that the investigator considers as an AE should be reported as such.
At each visit, the investigator should actively assess as to whether any of the following 
adverse events have occurred during the interval since the last visit:
•
Serotonin syndrome and signs or symptoms of serotonergism
•
Signs or symptoms of valvular heart disease or pulmonary hypertension, including 
dyspnea, dependent edema, congestive heart failure, or a new cardiac murmur

•
Impairments in attention and memory, and confusion, somnolence, and fatigue
•
Psychiatric disorders
•
Hypoglycemia in subjects with diabetes on concomitant anti-diabetes medications (using 
ADA definitions)
•
Priapism and hyperprolactinemia signs and symptoms should be recorded at each visit 
and whenever reported
•
Hypersensitivity reactions
Any such events should be recorded as adverse events.  Serotonin syndrome, valvular heart 
disease, pulmonary hypertension, and priapism should always be reported as serious adverse 
events (SAEs) (See Section 9.5.1.5.2 for a complete list of adverse events that should always 
be considered as Serious).  (revised per Amendment 03)
Events of hypoglycemia in subjects with diabetes on concomitant anti-diabetes medication 
should be captured as per Section 9.5.2.  Severe symptomatic events of hypoglycemia should 
always be reported as an SAE as per Section 9.5.1.5.2.  (revised per Amendment 03)
It is the responsibility of the investigator to review the results of the Leiter-3, C-SSRS, and 
PHQ-9 for all subjects and determine if any result constitutes an AE.  Medical and scientific 
judgment should be exercised in deciding whether an isolated suicidality rating scale 
response should be classified as an AE (see Section 9.5.1.5.10 for a description of the 
C-SSRS).  (revised per Amendment 01)
All AEs must be monitored until symptom resolution, or until the condition stabalizes.  
(revised per Amendment 03)
Every effort must be made by the investigator to categorize each AE according to its 
severity and its relationship to the study treatment.
Assessing Severity of Adverse Events
Adverse events will be graded on a 3-point scale (mild, moderate, severe) and reported in the 
detail indicated on the CRF.  The definitions are as follows:
Mild
Discomfort noticed, but no disruption of normal daily activity
Moderate Discomfort sufficient to reduce or affect normal daily activity
Severe
Incapacitating, with inability to work or to perform normal daily activity
The criteria for assessing severity are different than those used for seriousness (see
Section 9.5.1.5.2 for the definition of an SAE).
Assessing Relationship to Study Treatment
Items to be considered when assessing the relationship of an AE to the study treatment are:

Page 48 of 84
•
Temporal relationship of the onset of the event to the initiation of the study treatment
•
The course of the event, especially the effect of discontinuation of study treatment or 
reintroduction of study treatment, as applicable
•
Whether the event is known to be associated with the study treatment or with other 
similar treatments
•
The presence of risk factors in the study subject known to increase the occurrence of the 
event
•
The presence of nonstudy, treatment-related factors that are known to be associated with 
the occurrence of the event
Classification of Causality
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question:
Is there a reasonable possibility that the study drug caused the AE?
Yes (related)
A causal relationship between the study drug and the AE is a reasonable 
possibility.
No (not related) A causal relationship between the study drug and the AE is not a 
reasonable possibility.
9.5.1.5.2
SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An SAE is any untoward medical occurrence that at any dose:
•
Results in death
•
Is life-threatening (ie, the subject was at immediate risk of death from the AE as it 
occurred; this does not include an event that, had it occurred in a more severe form or 
was allowed to continue, might have caused death)
•
Requires inpatient hospitalization or prolongation of existing hospitalization
•
Results in persistent or significant disability/incapacity
•
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug)
Other important medical events that may not be immediately life-threatening or result in 
death or hospitalization but, when based on appropriate medical judgment, may jeopardize 
the subject or may require intervention to prevent one of the outcomes in the definition of 
SAE listed above should also be considered SAEs.  Medical and scientific judgment should 
be exercised in deciding whether expedited reporting is appropriate in such situations. 
For this study, the following events should always be considered serious and reported as an 
important medical event if it does not meet other serious criteria:

•
Serotonin syndrome (must have at least 1 of the following: 
Spontaneous clonus; 
Inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus)
•
Psychosis
•
Suicidal behavior
•
Priapism
•
New onset valvular heart disease
•
New onset pulmonary hypertension
•
Malignant neoplasms (revised per Amendment 03)
•
Fibroadenomas of the breast or ductal carcinoma in situ
•
Severe symptomatic hypoglycemia (revised per Amendment 03)
In addition to the above, events associated with special situations include pregnancy or 
exposure to study drug through breastfeeding; AEs associated with study drug overdose, 
misuse, abuse, or medication error.  These events associated with special situations are to be 
captured using the SAE procedures but are to be considered as SAEs only if they meet 1 of 
the above criteria.  All AEs associated with special situations are to be reported on the CRF 
whether or not they meet the criteria for SAEs.  
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization.
The following hospitalizations are not considered to be SAEs because there is no “AE” (ie, 
there is no untoward medical occurrence) associated with the hospitalization:
•
Hospitalizations for respite care
•
Planned hospitalizations required by the protocol  
•
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed after study drug administration)
•
Hospitalization for administration of study drug or insertion of access for administration 
of study drug
•
Hospitalization for routine maintenance of a device (eg, battery replacement) that was in 
place before study entry

9.5.1.5.10 OTHER SAFETY ASSESSMENTS
Leiter-3
The Leiter International Performance Scale–Third Edition (Leiter-3) is widely used 
non verbal measure of intelligence, memory, and attention in those between the ages of 3 and 
75 years. 
The Attention/Memory Battery consists of 5 subtests: 2 measure nonverbal 
attention; 2 measure memory; and 1 measures cognitive interference (nonverbal Stroop test). 
These subtests are combined to produce a Memory and Processing Speed composite scores, 
normalized to a mean of 100 and standard deviation of 15. The Leiter-3 will be used to 
assess lorcaserin effects on cognition, specifically, attention and memory. In addition, signs 
and symptoms of cognition-related AEs, including impairments in attention, memory, and 
adverse effects on schoolwork will be captured in the eCRF. (revised per Amendment 01)
PHQ-9
The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and 
measuring the severity of depression:

The PHQ-9 incorporates Diagnostic and Statistical Manual of Mental Disorders, 4th 
Edition (DSM-IV) depression diagnostic criteria with other leading major depressive 
symptoms into a brief self-report tool.

The tool rates the frequency of the symptoms which factors into the scoring severity 
index.

Question 9 on the PHQ-9 screens for the presence and duration of suicide ideation.

A follow-up, non-scored question on the PHQ-9 assigns weight to the degree to which 
depressive problems have affected the patient's level of function. 
C-SSRS
The C-SSRS collects information pertinent to suicidal ideation and actions.  It consists of a 
Baseline version which will be administered at baseline and a Since Last Visit version which 
will be administered at the remaining visits.  C-SSRS will be used to assess signal of 
depression and suicidal ideation or behavior. Qualified personnel must evaluate positive 
responses on the C-SSRS and take appropriate action as detailed in the training and

Reporting of Serious Adverse Events, Pregnancy, and Events Associated 
with Special Situations
9.5.4.1
Reporting of Serious Adverse Events
All SAEs, regardless of their relationship to study treatment, must be reported on a 
completed SAE form by email or fax as soon as possible but no later than 1 business 
day from the date the investigator becomes aware of the event.
SAEs, regardless of causality assessment, must be collected through the through the last visit
and for 28 days after the subject’s last dose.  All SAEs must be followed to resolution or, if 
resolution is unlikely, to stabilization.  Any SAE judged by the investigator to be related to 
the study treatment or any protocol-required procedure should be reported to the sponsor 
regardless of the length of time that has passed since study completion.
The detailed contact information for reporting of SAEs is provided in the Investigator Study 
File.
For urgent safety issues, please ensure all appropriate medical care is administered to the 
subject and contact the appropriate study team member listed in the Investigator Study File.
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report.  This includes the investigator’s assessment of causality.
Any follow-up information received on SAEs should be forwarded within 1 business day of 
its receipt.  If the follow-up information changes the investigator’s assessment of causality, 
this should also be noted on the follow-up SAE form.
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested by 
the sponsor.
The investigator must notify his/her IRB/IEC of the occurrence of the SAE, in writing, if 
required by their institution.  A copy of this communication must be forwarded to the sponsor 
to be filed in the sponsor’s Trial Master File.
9.5.4.2
Reporting of Pregnancy and Exposure to Study Drug through Breastfeeding
Any pregnancy in which the estimated date of conception is either before the last visit or 
within 28 days of last study treatment or any exposure to study drug through breastfeeding 
during study treatment or within 28 days of last study treatment must be reported.
If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, this 
should be reported regardless of the length of time that has passed since the exposure to study 
treatment.

A congenital anomaly, death during perinatal period, an induced abortion, or a spontaneous 
abortion are considered to be an SAE and should be reported in the same time frame and in 
the same format as all other SAEs (see Section 9.5.4.1).
Pregnancies or exposure to study drug through breastfeeding must be reported by fax or 
email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy.  The contact information for the reporting of pregnancies 
and exposure to study drug through breastfeeding is provided in the Investigator Study File.  
The Pregnancy Report Form must be used for reporting.  All pregnancies must be followed to 
outcome.  The outcome of the pregnancy must be reported as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the outcome.
A subject who becomes pregnant must be withdrawn from the study. 
9.5.4.3
Reporting of Events Association with Special Situations
9.5.4.3.1
REPORTING OF ADVERSE EVENTS ASSOCIATED WITH STUDY DRUG OVERDOSE,
MISUSE, ABUSE, OR MEDICATION ERROR
Adverse events associated with study drug overdose, misuse, abuse, and medication error 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication error are defined as follows:
Overdose
Accidental or intentional use of the study drug in an amount higher
than the protocol-defined dose
Misuse
Intentional and inappropriate use of study drug not in accordance with 
the protocol or authorized dose, route of administration, or 
indication(s) or use of prescription-only study drug without a 
prescription
Abuse
Sporadic or persistent intentional excessive use of study drug 
accompanied by harmful physical or psychological effects
Medication error
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of the 
healthcare professional, subject, or consumer.  Such events may be 
related to professional practice, healthcare products, occupational 
exposure, procedures, or
systems,
including prescribing,
order 
communication,
product
labeling, 
packaging, 
nomenclature,
compounding,
dispensing,
distribution,
administration, education,
monitoring, or use.
All AEs associated with overdose, misuse, abuse, or medication error should be captured on 
the Adverse Event CRF and also reported using the procedures detailed in Section 9.5.4.1
even if the AEs do not meet serious criteria.  Abuse is always to be captured as an AE.  If the 
AE associated with an overdose, misuse, abuse, or medication error does not meet serious

Page 60 of 84
criteria, it must still be reported using the SAE form and in an expedited manner but should 
be noted as nonserious on the SAE form and the Adverse Event CRF.
9.5.4.3.2
REPORTING OF STUDY-SPECIFIC EVENTS
Study-specific events (listed below) should always be considered as serious important 
medical events and be entered on the Adverse Event CRF and reported using the procedures 
detailed in Reporting of Serious Adverse Events (Section 9.5.4.1), even if the study-specific 
event does not meet other serious criteria.  

Serotonin syndrome
Must have at least 1 of the following: 
spontaneous clonus; 
inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus

Psychosis

Suicidal behavior 

Priapism

New onset of valvular heart disease

New onset pulmonary hypertension

Malignant neoplasms (revised per Amendment 03)

Fibroadenomas of the breast or ductal carcinoma in situ


Severe symptomatic hypoglycemia (revised per Amendment 03)
Subject-reported episodes of hypoglycemia or decreased blood sugar should be captured on 
the eCRF according to the following guidelines:

Psuedo-hypoglycemia:  An event during which the person with diabetes reports any of 
the typical symptoms of hypoglycemia and interprets those as indicative of hypoglycemia 
with a measured plasma glucose concentration >70 mg/dL (>3.9 mmol/L) but 
approaching that level.  (revised per Amendment 03)

Probable symptomatic hypoglycemia:  An event during which symptoms typical of 
hypoglycemia are not accompanied by a plasma glucose determination but that was 
presumably caused by a plasma glucose concentration ≤ 70 mg/dL (≤ 3.9 mmol/L)
(revised per Amendment 03)

Asymptomatic hypoglycemia: 
An event not accompanied by typical symptoms of 
hypoglycemia but with a measured plasma glucose concentration ≤ 70 mg/dL (≤ 
3.9 mmol/L) (revised per Amendment 03)

Documented symptomatic hypoglycemia: An event during which typical hypoglycemia 
symptoms are accompanied by a measured plasma glucose ≤70 mg/dL (≤3.9 mmol/L) 
(revised per Amendment 03)


Severe hypoglycemia: 
An event requiring assistance of another person to actively 
administer carbohydrate, glucagon or other resuscitation actions. Plasma glucose 
measurements may not be available during such an event, but neurological recovery 
attributable to the restoration of plasma glucose to normal is considered sufficient 
evidence that the event was induced by a low plasma glucose concentration (revised per 
Amendment 03)
See Section 9.4.6 (Prior and Concomitant Therapy) for directions on the recommendations 
for possible adjustment to antihyperglycemic medication doses in response to reported 
episodes of hypoglycemia.  (revised per Amendment 03)
9.5.4.4
Expedited Reporting
The sponsor must inform investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (ie, within 
specific time frames).  For this reason, it is imperative that sites provide complete SAE 
information in the manner described above.
9.5.4.5
Breaking the Blind
In the case of a medical emergency where the appropriate treatment of the subject requires 
knowledge of the study treatment given, the investigator may break the randomization code 
for an individual subject.  In all such cases, the AE necessitating the emergency blind break 
will be handled as an SAE in accordance with the procedures indicated above.  Any broken 
code will be clearly justified and documented.  The medical monitor must be notified 
immediately of the blind break.
9.5.4.6
Regulatory Reporting of Adverse Events
Adverse events will be reported by the sponsor or a third party acting on behalf of the 
sponsor to regulatory authorities in compliance with local and regional law and established 
guidance.  The format of these reports will be dictated by the local and regional 
requirements.
9.5.5
Completion/Discontinuation of Subjects
The investigator may withdraw the subject from the study at any time for safety or 
administrative reasons.  A subject may elect to discontinue the study at any time for any 
reason.  All subjects will continue in the study until the 52-week evaluation is completed.  
Subjects who discontinue study drug prematurely will continue to be evaluated on for all 
study assessments until study completion.  All attempts will be made to capture height and 
weight in all subjects whether or not they are still on IP at the end of the study.  All subjects 
who discontinue the study are to complete the study’s early discontinuation procedures 
indicated in the Schedule of Procedures/Assessments Table 2). (revised per Amendment 03)
The investigator will promptly explain to the subject involved that the study will be 
discontinued for that subject and provide appropriate medical treatment and other necessary 
measures for the subject.  A subject who has ceased to return for visits will be contacted by

mail, phone, or other means to gather information such as the reason for failure to return, the 
status of treatment compliance, the presence or absence of AEs, and clinical courses of signs 
and symptoms.
Subjects who discontinue early from the study will be discontinued for 1 of these primary 
reasons: AE(s), lost to follow-up, subject choice, withdrawal of consent, pregnancy, study 
terminated by sponsor, or other.  In addition to the primary reason, the subject may indicate
1 or more of the secondary reasons for discontinuation. Study disposition information will 
be collected on the Subject Disposition CRF. If “lost to follow-up” is recorded in clinical 
data base, appropriate queries will be sent to investigators in order to collect all the relevant 
reasons for missing data.  (revised per Amendment 03)
Every effort, including proper training of all study participants and their parent/guardian, 
should be made in order to achieve optimal subject retention and prevent missing data, 
especially for the Week 52 primary endpoint.  A retention plan to help avoid missing data 
will be developed and included in study manual. (revised per Amendment 03)
A subject removed from the study for any reason may not be replaced.
9.5.6
Abuse or Diversion of Study Drug
During the study, the investigator will report any concern about abuse or diversion of study 
drugs by completing the Abuse or Diversion of Study Drug CRF.  The DEA Registrant has 
the responsibility to comply with local, state, and Federal laws to notify the Field Division 
Office of the DEA of any theft or significant loss of any controlled substances upon 
discovery of such theft or loss.
9.5.7
Confirmation of Medical Care by Another Physician
The investigator will instruct subjects to inform site personnel when they are planning to 
receive medical care by another physician.  At each visit, the investigator will ask the subject 
whether he or she has received medical care by another physician since the last visit or is 
planning to do so in the future.  When the subject is going to receive medical care by another 
physician, the investigator, with the consent of the subject, will inform the other physician 
that the subject is participating in the clinical study.
9.6
Data Quality Assurance
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines.  Site audits 
will be made periodically by the sponsor’s or the CRO’s qualified compliance auditing team, 
which is an independent function from the study team responsible for conduct of the study.
9.6.1
Data Collection
Data required by the protocol will be collected on the CRFs and entered into a validated data 
management system that is compliant with all regulatory requirements.  As defined by ICH

guidelines, the CRF is a printed, optical, or electronic document designed to record all of the 
protocol-required information to be reported to the sponsor on each study subject.
Data collection on the CRF must follow the instructions described in the CRF Completion 
Guidelines.  The investigator has ultimate responsibility for the collection and reporting of all 
clinical data entered on the CRF.  The investigator or designee as identified on Form 
FDA 1572 must sign the completed CRF to attest to its accuracy, authenticity, and 
completeness.
Completed, original CRFs are the sole property of Eisai and should not be made available in 
any form to third parties without written permission from Eisai, except for authorized 
representatives of Eisai or appropriate regulatory authorities.
9.6.2
Clinical Data Management
All software applications used in the collection of data will be properly validated following 
standard computer system validation that is compliant with all regulatory requirements.  All 
data, both CRF and external data (eg, laboratory data), will be entered into a clinical system.
9.7
Statistical Methods
All statistical analyses will be performed by the sponsor or designee after the study is 
completed and the database is locked and released for unblinding.  Statistical analyses will be 
performed using WinNonlin and SAS software or other validated statistical software as 
required.  Details of the statistical analyses will be included in a separate statistical analysis 
plan (SAP).
9.7.1

Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, while the PP will 
be used as a supportive analysis.  Unless specified otherwise, a 2-sided α=0.05 significance 
level will be used for all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change 
from baseline in BMI will be analyzed using analysis of covariance model (ANCOVA) with 
factors of treatment, sex (male and female) as fixed effect, and the baseline age and BMI as 
covariates.  The missing values will be imputed using a pattern mixture model utilizing 
multiple imputation (MI) assuming the missing values are missing not at random (MNAR).  
The missing values will be imputed at each visit using all available values including the 
retrieved measurement from the postdiscontinuation data.  The details of the analysis model 
and missing value imputation method will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis: The same primary efficacy analyses described above will be repeated based 
on the PP.

Change from baseline in standardized BMI score (Z-score): The same primary efficacy 
analyses described above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed 
and will be described in the SAP.  
Key Secondary Efficacy Analysis
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 
5% BMI reduction at Week 52.  The secondary efficacy endpoint will be analyzed only if the 
test for the primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be 
analyzed using a logistic regression model with factors of treatment, and sex (male and 
female), and baseline BMI as a covariate using FAS.  Subjects with any missing assessment 
at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be 
analyzed using mixed effect model repeated measurement analysis (MMRM) on the FAS for 
study treatment compared to placebo, as appropriate. The model will include all data and will 
include treatment, time, and the interaction of treatment by time as fixed effects, with 
adjustment for sex (male versus female), BMI and age at baseline, and subject as a random 
effect.  (revised per Amendment 03)
Treatment by time interaction will be used to construct the treatment comparisons at a 
specific time.  The MMRM model assumes that the missing data are missing at random and

makes use of all available data even if a subject has missing data at some post-baseline visits.  
An unstructured covariance matrix will be used, and if the model fails to converge, then an 
autoregressive matrix will be used.  (revised per Amendment 03)
Categorical variables will be analyzed using the Cochran Mantel Haenszel test, Chi-square 
test, or logistic regression as appropriate.  Additional analysis may be performed as needed 
using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male 
and female), race (American Indian or Alaska Native, Asian, Black or African American, 
Native Hawaiian or other Pacific Islander, or White), and age. Additional subgroups may be 
explored, if deemed necessary.  (revised per Amendment 03)
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and 
sensitivity analyses.

Pharmacokinetic, Pharmacodynamic, Pharmacogenomic, and Other Biomarker
Analyses
9.7.1.7.1
PHARMACOKINETIC ANALYSES
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling.  The effect of covariates, such as baseline characteristics
or demographics, on PK will be explored.  Derived exposure parameters such as the 
maximum observed concentration and the area under the concentration-time curve from time
0 to 24 hours at steady-state will be calculated from the final PK model using individual 
posterior estimates of the PK parameters and from dosing history.  The PK analysis set will 
be used for this analysis.
9.7.1.7.2
PHARMACODYNAMIC ANALYSES
Change from Baseline in BMI will be assessed as the PD endpoint.  The PD analysis set will 
be used for this analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% 
and ≥10% BMI reduction, and change in waist circumference from baseline) will also be 
assessed as part of the PD analysis.  The PK/PD analysis set will be used for this analysis.
9.7.1.7.3
PHARMACOKINETIC/PHARMACODYNAMIC ANALYSES
Population PK/PD modeling will be used to explore the relationship between lorcaserin 
plasma exposure and response, including but not limited to change in BMI from baseline and 
the probability of achieving at least a 5% and at least a 10% change in BMI from baseline to 
Week 52.  Additionally, exposure-safety relationships for select safety parameters may be 
explored graphically, depending on the data at the end of study.  Any emergent relationship 
may be modeled as appropriate.  Any parameters based on the study data may be considered 
for exploratory assessment for its relationship to PK.

Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments 
including the incidence of AEs (including changes from baseline in physical examination, 
neuromuscular sign assessment for serotonin syndrome, and signs and symptoms of priapism 
and hyperprolactinemia), out-of-normal-range laboratory safety test values, change from 
baseline in laboratory safety test values, ECGs, vital sign measurements, bone mineral 
density and content, total body fat mass and total body lean mass will be summarized by 
treatment group using descriptive statistics or frequency count as appropriate.  (revised per 
Amendments 01 and 03)
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
9.7.1.8.1
EXTENT OF EXPOSURE
Subjects will receive Belviq XR 20 mg or placebo QD for up to 52 weeks. The extent of 
exposure will be characterized by duration of exposure (in weeks) for each treatment group.
Duration of exposure will be defined as the number of weeks between the date the subject 
received the 1st dose of study drug and the date the subject received the last dose of study 
drug.  Duration of exposure will be summarized using descriptive statistics by treatment 
group.  In addition, the duration of exposure will be categorized and will be summarized 
using frequency count by treatment group.
9.7.1.8.2
ADVERSE EVENTS
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities 
(MedDRA).  Adverse events will be coded to the MedDRA (Version 18.0 or higher) lower 
level term closest to the verbatim term.  The linked MedDRA PT and primary system organ 
class (SOC) are also captured in the database.
A treatment-emergent AE (TEAE) is defined as an AE that emerges during treatment (up to 
28 days after the last dose of study drug), having been absent at pretreatment (Baseline) or 
•
Reemerges during treatment (up to 28 days after the last dose of study drug), having been 
present at pretreatment (Baseline) but stopped before treatment, or 
•
Worsens in severity during treatment relative to the pretreatment state, when the AE is 
continuous.
Only those AEs that were treatment emergent will be included in summary tables.  All AEs, 
treatment emergent or otherwise, will be presented in subject data listings.


Incidence of treatment-related TEAEs by SOC and PT

Incidence of TEAEs by SOC, PT and maximum severity (mild, moderate, or severe)

Incidence of treatment-related TEAEs by SOC, PT, and maximum severity (mild, 
moderate, or severe)

Incidence of TEAEs by SOC, PT, and relationship to study drug (Yes [related] or No [not 
related]) 
A subject will be counted only once within a SOC or PT, if the subject experienced more 
than 1 TEAE within a specified SOC and PT.
The following summaries will also be presented for the treatment-emergent SAEs.

Incidence of TEAEs leading to death

Incidence of treatment-emergent SAE by SOC and PT

Incidence of treatment-related treatment-emergent SAE by SOC and PT
In addition, subjects with TEAEs leading to discontinuation from study drug and AEs of 
special interest as described in Section 9.5.4.3.2 will be summarized by MedDRA SOC and 
PT for each treatment group. 
9.7.1.8.3
LABORATORY VALUES
Laboratory results will be summarized using Système International units, as appropriate.  For 
all quantitative parameters listed in Section 9.5.1.5.3, the actual value and the change from 
baseline to each postbaseline visit and to the end of treatment (defined as the last 
on-treatment value) will be summarized by visit and treatment group using descriptive 
statistics.  Percentages will be based on the number of subjects with both nonmissing 
baseline and relevant postbaseline results.
Laboratory test results will be assigned a low/normal/high (LNH) classification according to 
whether the value was below (L), within (N), or above (H) the laboratory parameter’s 
reference range.  Within-treatment comparisons for each laboratory parameter will be based 
on 3-by-3 tables (shift tables) that compare the baseline LNH classification to the LNH 
classification at the End of Treatment and the Follow-Up visits.  Similar shift tables will also

presents the criteria that will be used to identify subjects with 
treatment-emergent markedly abnormal laboratory values (TEMAV).  Except for phosphate, 
a TEMAV is defined as a postbaseline value with an increase from baseline to a grade of 2 or 
higher.  For phosphate, a TEMAV was defined as a postbaseline value with an increase from 
baseline to a grade of 3 or higher.  When displaying the incidence of TEMAVs, each subject 
may be counted once in the laboratory parameter high and in the laboratory parameter low 
categories, as applicable.
9.7.1.8.4
VITAL SIGNS
Descriptive statistics for vital signs parameters (eg, systolic and diastolic BP, pulse, 
respiratory rate, temperature, weight) and changes from baseline will be presented by visit
and treatment group.
9.7.1.8.5
ELECTROCARDIOGRAMS
For each ECG parameter (including PR interval, RR interval, QRS interval, QT interval, QTc
interval (Bazett formula), QTc interval (Fridericia formula), and heart rate), the actual value 
and change from baseline will be summarized by visit and treatment group using descriptive 
statistics. 
Shift tables will present changes from baseline in ECG interpretation (categorized as normal; 
abnormal, not clinically significant; and abnormal, clinically significant) to end of treatment. 
Maximum postbaseline QTc (Bazett) and QTc (Fridericia) will also be tabulated by treatment 
group as follows:

Number (percentage) of subjects in greater than 450 msec, greater than 480 msec, and 
greater than 500 msec during the treatment, and

Number (percentage) of subjects with an increment of greater than 30 msec and greater 
than 60 msec from the baseline visit.

OTHER SAFETY ANALYSES
Other safety assessments including adolescent growth evaluations using 95th percentile CDC 
growth charts and bone age using x-ray of the hand, sexual maturation as measured in Tanner 
Staging, study drug effect on cognition assessed by Leiter-3, assessment of suicidality using 
C-SSRS, depression assessment using PHQ-9, bone mineral density and content, total body 
fat mass, and total body lean mass using DEXA will be summarized by treatment group at 
each scheduled visit.  For echocardiographic assessments, the proportion of subjects who 
develop FDA-defined valvulopathy, the proportion of subjects who develop pulmonary 
hypertension (defined as when a subject’s SPAP is

group at Week 28 and Week 52. (revised per Amendments 01 and 03)
9.7.2
Determination of Sample Size
The proposed sample size is based on the comparison of the primary efficacy endpoint, 
change from Baseline in BMI at Week 52 between the Belviq XR 20-mg treatment group and 
placebo group.  Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 
260 subjects in a 1:1 ratio (n=130 in the Belviq XR 20-mg treatment group; n=130 in the 
placebo group) will have at least 80% power to detect a treatment difference of 1 kg/m2 in 
BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at 
least a 5% BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, 
this sample of 260 subjects (130 subjects for Belviq XR 20 mg and 130 subjects for placebo) 
will also have greater than 78% power to detect an absolute difference of 20% between the 
Belviq XR 20-mg group and placebo group, using a 2-sided Chi-Square test with α=0.05.  
The assumption used in the sample size calculation is based on the 2 pivotal lorcaserin 
studies, APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

11 PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE 
PROCEDURES)
11.1
Changes to the Protocol
Any change to the protocol requires a written protocol amendment or administrative change 
that must be approved by the sponsor before implementation.  Amendments specifically 
affecting the safety of subjects, the scope of the investigation, or the scientific quality of the 
study require submission to health or regulatory authorities as well as additional approval by 
the applicable IRBs/IECs.  These requirements should in no way prevent any immediate 
action from being taken by the investigator, or by the sponsor, in the interest of preserving 
the safety of all subjects included in the study.  If the investigator determines that an 
immediate change to or deviation from the protocol is necessary for safety reasons to 
eliminate an immediate hazard to the subjects, the sponsor’s medical monitor and the 
IRB/IEC for the site must be notified immediately.  The sponsor must notify the health or 
regulatory authority as required per local regulations.
Protocol amendments that affect only administrative aspects of the study may not require 
submission to health or regulatory authority or the IRB/IEC, but the health or regulatory 
authority and IRB/IEC should be kept informed of such changes as required by local 
regulations.  In these cases, the sponsor may be required to send a letter to the IRB/IEC and 
the Competent Authorities detailing such changes.
11.2
Adherence to the Protocol
The investigator will conduct the study in strict accordance with the protocol (refer to ICH 
E6, Section 4.5).
11.3
Monitoring Procedures
The sponsor’s/CRO’s CRA will maintain contact with the investigator and designated staff 
by telephone, letter, or email between study visits.  Monitoring visits to each site will be 
conducted by the assigned CRA as described in the monitoring plan.  The investigator will 
allow the CRA to inspect the clinical, laboratory, and pharmacy facilities to assure 
compliance with GCP and local regulatory requirements.  The CRFs and subject’s 
corresponding original medical records (source documents) are to be fully available for 
review by the sponsor’s representatives at regular intervals.  These reviews verify adherence 
to study protocol and data accuracy in accordance with local regulations.  All records at the 
site are subject to inspection by the local auditing agency and IRB/IEC review.

In accordance with ICH E6, Section 1.52, source documents include, but are not limited to 
the following:
•
Clinic, office, or hospital charts
•
Copies or transcribed health care provider notes which have been certified for accuracy 
after production
•
Recorded data from automated instruments such as IxRS, x-rays, and other imaging 
reports, (eg, sonograms, computerized tomography scans, magnetic resonance images, 
radioactive images, ECGs, rhythm strips, EEGs, polysomnographs, pulmonary function 
tests) regardless of how these images are stored, including microfiche and photographic 
negatives
•
Pain, quality of life, or medical history questionnaires completed by subjects
•
Records of telephone contacts
•
Diaries or evaluation checklists
•
Drug distribution and accountability logs maintained in pharmacies or by research 
personnel
•

documentation and urine dip-sticks)
•
Correspondence regarding a study subject’s treatment between physicians or memoranda 
sent to the IRBs/IECs
•
CRF components (eg, questionnaires) that are completed directly by subjects and serve as 
their own source
11.4
Recording of Data
A CRF is required and must be completed for each subject by qualified and authorized 
personnel.  All data on the CRF must reflect the corresponding source document, except 
when a section of the CRF itself is used as source document.  Any correction to entries made 
on the CRF must be documented in a valid audit trail where the correction is dated, the 
individual making the correct is identified, the reason for the change is stated, and the 
original data are not obscured.  Only data required by the protocol for the purposes of the 
study should be collected.
The investigator must sign each CRF.  The investigator will report the CRFs to the sponsor 
and retain a copy of the CRFs.
11.5
Identification of Source Data
All data to be recorded on the CRF must reflect the corresponding source documents.

11.6
Retention of Records
The circumstances of completion or termination of the study notwithstanding, the 
investigator is responsible for retaining all study documents, including but not limited to the 
protocol, copies of CRFs, the Investigator's Brochure, and regulatory agency registration 
documents (eg, Form FDA 1572 ICFs, and IRB/IEC correspondence).  In addition, the 
sponsor will send a list of treatment codes by study subject to the investigator after the 
clinical database for this study has been locked.  The site should plan to retain study 
documents, as directed by the sponsor, for at least 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region or at least 3 years have elapsed since the formal 
discontinuation of clinical development of the investigational product.
It is requested that at the completion of the required retention period, or should the 
investigator retire or relocate, the investigator contact the sponsor, allowing the sponsor the 
option of permanently retaining the study records.
11.7
Auditing Procedures and Inspection
In addition to the routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of ICH GCP and all applicable local 
regulations.  If a government regulatory authority requests an inspection during the study or 
after its completion, the investigator must inform the sponsor immediately.
11.8
Handling of Study Drug
All study drugs will be supplied to the PI (or a designated pharmacist) by the sponsor.  Drug 
supplies must be kept in an appropriate secure area (eg, locked cabinet) and stored according 
to the conditions specified on the drug labels.  Investigational product will be stored in 
accordance with the DEA Regulations for Scheduled III - V Drugs and labeled storage 
conditions.  The investigator (or a designated pharmacist) must maintain an accurate record 
of the shipment and dispensing of the study drug in a drug accountability ledger, a copy of 
which must be given to the sponsor at the end of the study.  An accurate record of the date 
and amount of study drug dispensed to each subject must be available for inspection at any 
time.  The CRA will visit the site and review these documents along with all other study 
conduct documents at appropriate intervals once study drug has been received by the site.
All drug supplies are to be used only for this study and not for any other purpose.  The 
investigator (or site personnel) must not destroy any drug labels or any partly used or unused 
drug supply before approval to do so by the sponsor.  At the conclusion of the study and as 
appropriate during the study, the investigator (or a designated pharmacist) will return all used 
and unused drug containers, drug labels, and a copy of the completed drug disposition form 
to the sponsor’s CRA.

Appendix 2
Family-Based Lifestyle Program
Program Overview
All subjects and their caregivers (participating parent or guardian) in Study 403 will be 
encouraged to participate in a standardized weight management program for adolescents 
consisting of multicomponent behavior therapy.  The therapy will focus on healthy eating, 
physical activity, and lifestyle changes that will facilitate weight loss and weight-loss 
maintenance. The role of the caregivers is to support their child or adolescents’ lifestyle 
changes and their taking of study medication.
The objectives of this program are as follows:

Develop a weight management program for all Belviq XR study participants and their 
caregivers (caregivers are instructed in methods to support their adolescents’ progress but 
caregivers are themselves not instructed to lose weight or take medication)

Standardize the weight management program across all study sites

Maximize participant retention

Promote participant’s adherence to both taking study medication and following the 
lifestyle program

Study drug administration will 
be taken at approximately the 
same time each day.  On the 
days of PK sampling and the 
day before the subjects come to 
the clinic for PK sampling, 
study drug will be taken in the 
morning and doses recorded 2 
days prior to the clinic visit.
This will ensure lower variability

Subjects with symptoms or 
signs of cardiac valvular disease 
or pulmonary hypertension are 
not required to have further 
evaluation by centralized 
echocardiogram assessment.  In 
addition, no adjudication will be 
performed.  Local 
echocardiograms can be 
performed if deemed medically 
necessary by the investigator.
This 
change 
allows 
for 
the 
investigator to make the decision to 
perform local echocardiograms on a 
pediatric subject if deemed medically 
indicated rather than burden the 
subject to undergo a mandated, 
unnecessary procedure.

A single dose pharmacokinetic study 
in pediatric obese subjects (APD356-
A001-026) indicated that patients with 
body weight greater than or equal to 
60 kg can be administered a dose 
similar to that given to adults and 
adolescents.  Based on Centers for 
Disease Control and Prevention 
(CDC) growth chart data, almost all 
subjects over 9 years of age are likely 
to be at or over 60 kg body weight.  
Therefore, children age 9 to 11 years 
have been included in the current 
study.

Study Design
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in obese adolescents, 
ages 12 to 17 years.  Approximately 260 subjects will be randomized in a 1:1 ratio to Belviq XR 20 mg QD
(130 subjects) and placebo (130 subjects).  Subjects will be stratified by sex.  Subjects will receive Belviq XR
20 mg or matched placebo QD in a 1:1 ratio for up to 52 weeks. A recruitment plan will be developed to ensure 
at least 20% of younger subjects (12 to 13 years of age) are enrolled in the study.  Throughout the duration of 
the study, subjects will be encouraged to adhere to a lifestyle modification program that includes a 
standardized, age-appropriate diet and exercise counseling. (revised per Amendments 02 and 03)
The study will consist of 2 phases: Prerandomization and Randomization.  The Prerandomization Phase will 
last up to 30 days and consist of 1 visit during which subjects will be screened for eligibility.  The 
Randomization Phase consists of a Treatment Period and a Follow-Up Period.  The Treatment Period will last 
for a maximum of 52 weeks, with visits at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52.  The Follow-Up Period will 
extend from the End of Treatment (EOT) visit to the End of Study visit.
Subjects who screen fail can be re-screened only once after 30 days.  All subjects will continue in the study 
until the 52-week evaluation is completed.  Subjects who discontinue treatment prematurely will be followed up 
until study completion.  All attempts will be made to capture height and weight in all subjects whether or not 
they are still on study drug at the end of the study.  (revised per Amendment 03)
Study sites will be selected to ensure adequate representation of adolescents of ethnic and racial minorities.  
(revised per Amendment 03)
Data Monitoring Committee (revised per Amendment 03)
A Data Monitoring Committee (DMC) will be established to monitor and conduct periodic safety review of 
unblinded data. DMC members will be chosen based on their expertise in evaluating these clinical events. A 
separate DMC charter will be established.
Number of Subjects
Approximately 500 subjects will be screened to provide 260 randomized subjects.  (revised per Amendment 02)
Inclusion Criteria
1.
Healthy male or female adolescents, age 12 to 17 years (inclusive) at Screening, with an initial BMI that is 
greater than or equal to the United States (US)-weighted mean of the 95th percentile based on age and sex
with a body weight greater than 60 kg.  Subjects with T2DM may have a pre-existing or new diagnosis of

T2DM.
Subjects with pre-existing T2DM should have prior documentation consistent with the diagnosis and/or be 
on active pharmacotherapy for T2DM.  
Subjects with a new diagnosis of T2DM (ie, diagnosed at Screening) should be based on the 2016 
American Diabetes Association (ADA) guidelines.  The diagnostic criteria are met if a subject has 
unequivocal hyperglycemia (random plasma glucose ≥200 mg/dL (11.1 mmol/L) with classic symptoms of 
hyperglycemia or hyperglycemic crisis) OR any of the following criteria are observed and confirmed:
◦
HbA1c ≥6.5% 
◦
fasting plasma glucose (FPG) ≥126 mg/dL (7.0 mmol/L) 
◦
2-hour plasma glucose ≥200 mg/dL (11.1 mmol/L) by an oral glucose tolerance test (OGTT)
All T2DM subjects must have an HbA1c <10% at Screening.  If subjects are being or need to be treated 
with antidiabetic agents, the T2DM treatment regimen must be stable for at least 3 months before 
randomization.  A single rescreen is allowed following stabilization.  Stable control refers to minimal dose 
changes to existing medications for glycemic control and no medications being initiated for glycemic 
control in the 3 months before Randomization.  Minimal changes are defined as a change without any 
change in dose frequency, no add-on or discontinuation of other antidiabetic agents, and the subject has not 
been hospitalized due to hypo- or hyperglycemic events. (revised per Amendment 03)
2.
Subjects and their families not planning to move away from the area for the duration of the study
3.
Able and willing to comply with all aspects of the study, including a standardized, reduced-calorie diet and 
an age-appropriate, increased physical activity program
4.
Considered in stable health in the opinion of the investigator
5.
Caregivers or guardians meet the following requirements:
a.
Able and willing to support and supervise study participation in the opinion of the investigator,
including consideration of any existing physical, medical, or mental condition that prevents 
compliance with the protocol
b.
Able and willing to personally comply with and execute all aspects of the study requirements for the 
caregivers or guardians
Exclusion Criteria
1.
Clinically significant new illness within 1 month before randomization that may affect the subject’s ability 
to fulfill the study requirements or significantly confound the assessments
2.

4.
Any of the following findings on Screening echocardiography:

Aortic regurgitation mild or greater

Mitral regurgitation moderate or greater

Mitral or aortic valve stenosis greater than mild (ie, aortic stenosis [AS]: jet >3.0 m/s, mean gradient 
>25 mm Hg, and aortic valve area [AVA] <1.5 cm2; MS: mean gradient >5 mm Hg and mitral valve 
area [MVA] <1.5 cm2)

Systolic pulmonary artery pressure (SPAP) >40 mmHg (and/or tricuspid regurgitation (TR) jet 
velocity >2.9 m/s)
In cases where an actual SPAP value is not measurable due to lack of adequate TR jet, the pulmonary flow 
acceleration time measured at the right ventricular outflow tract (RVOTAT), will be used to assess 
eligibility. Patients with a RVOTAT ≤100 msec will be excluded, suggesting an elevated mean SPAP; 
eligibility for the those patients with RVOTAT between 100 and 120 msec will be determined based on 
combined assessment of the TR jet, septal motion and right ventricular size.


stimulant medications (eg, Ritalin, Concerta, Biphetamine and Dexedrine)

benzodiazepines
The following concomitant medication guidelines/restrictions will apply:

Medications for the treatment of hypertension, dyslipidemia, or diabetes may be started, discontinued, or 
adjusted during the study according to local standards of care if, in the judgment of the investigator or the 
subject’s physician, such a change is medically indicated.

For diabetic subjects treated with sulfonylureas, insulin (note that subjects should not be enrolled as 
indicated in exclusion criteria), or other antidiabetic agents with hypoglycemic risk, the risk of 
hypoglycemic events may be higher if the subjects experience rapid and significant weight loss (more than 
10% weight reduction than at the previous visit).  It is recommended that the physician advise the subject 
to monitor their blood glucose more frequently and adjust their antidiabetic medications and diet 
accordingly. 

The antihyperglycemic medication dose would be considered for reduction in the event of 1 documented 
and otherwise unexplained hypoglycemic event (blood glucose concentration <65 mg/dL) or 2 
undocumented and otherwise unexplained suspected hypoglycemic events between any 2 scheduled visits. 
For subjects on more than 1 antihyperglycemic medication, it is recommended to reduce insulin first (if 
applicable), then the oral and/or other injectable antidiabetic agents.  If the previous criteria are met again 
following dose reduction, further dose reductions or cessation of 1 or more anti-hyperglycemic agents, are 
suggested.  See Section 9.5.4.2 for the definition and reporting of hypoglycemic events. 
To minimize the risk of cardiac valve toxicity, subjects must not initiate use of agents that have documented 
correlation with increased incidence of valvulopathy and/or pulumonary hypertension (eg, pergolide, 
ergotamine, methysergide, or cabergoline) during the study.  If any of the above agents are clinically warranted, 
and subjects initiate any of these agents, lorcaserin HCl should be discontinued but can be restarted on 
lorcaserin HCl after being off the medications above for 1 month.  Otherwise, the study medication should not 
be restarted, but the subject should continue all study visits.  (revised per Amendment 03)

proportion (%) of subjects achieving at least a 5% and at least a 10% BMI reduction.

Waist circumference (revised per Amendment 03)

Total body fat mass and total body lean mass will be determined centrally using DEXA in a subset of 
randomized subjects (selected prior to randomization) at selected sites at Baseline and Week 52/EOT
(revised per Amendment 03)

Measurement of systolic and diastolic BP, heart rate (taken after resting for 5 minutes), fasting lipids (total 
cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides), fasting plasma glucose, fasting insulin,
HbA1c, and Homeostasis Model Assessment (HOMA) IR to assess cardiovascular and metabolic risk 
profiles from Baseline to Week 52 (revised per Amendment 03)

Prehypertension and primary hypertension as defined by the Expert Panel on Integrated Guidelines for 
Cardiovascular Health and Risk Reduction in Children and Adolescents

Dyslipidemia as defined by the Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk 
Reduction in Children and Adolescents
Every effort will be made to ensure that at least 80% of randomized subjects will have an assessment of the 
primary efficacy endpoint regardless of whether or not the subject remained on study drug or completed other 
study assessments.  (revised per Amendment 03)
Pharmacokinetic Assessments
Blood samples (approximately 4 mL each) for PK assessment will be collected at Weeks 12, 28, 36, and 52 for 
analysis of Population PK. (revised per Amendment 01)
On the day of the Week 12, 28, and 52 clinic visits, subjects will be instructed not to take their study drug at 
home before the visit,but to bring their study drug to the clinic visit, and take their daily dose at the clinic.  
Two blood samples for determination of plasma concentrations of lorcaserin will be taken: 1 predose (within 
30 minutes before dosing), and 1 within 1 to 3 hours after dosing.  Dose times must be recorded for the last 
2 dosing times before the day of clinic visit. Week 52 PK samples should only be collected if the sample can be 
drawn within 60 hours of the last dose of study drug. (revised per Amendment 01)
On the day of the Week 36 clinic visit, subjects will take their study drug in the morning at home, and will be 
asked to visit the clinic within 4 to 6 hours of dosing that day, during which 1 blood sample for for PK 
assessments will be collected. Dose times must be recorded for the last 2 dosing times prior to the clinic visit.
(revised per Amendment 01)
Pharmacodynamic Assessments

Change from baseline in BMI 

Proportion (%) of subjects achieving at least a 5% and at least a 10% reduction in BMI

Other Safety Assessments
Effect on growth will be evaluated using the CDC growth chart and bone age determination by x-ray of the 
hand. Sexual maturation will be evaluated by assessing sex hormones and Tanner Staging.   
The C-SSRS will be used to assess all subjects in the study for any signal of depression or suicidal ideation or 
behavior at every visit.  Additionally, screening, diagnosing, monitoring, and measuring the severity of 
depression will be assessed using the PHQ-9 and effects on cognition will be assessed using the Leiter-3.  
(revised per Amendment 01)
Bone mineral density and content, total body fat mass and total body lean mass will be determined using DEXA 
in a subset of randomized subjects (selected prior to randomization) at selected sites.  (revised per Amendment 
03)
Echocardiographic assessments will be used to exclude subjects with FDA-defined valvulopathy, pulmonary 
hypertension, and other major cardiovascular disease (as outlined in Exclusion Criterion No. 3) during the 
Screening Period.  Additionally, cardiac valvular function and pulmonary systolic pressure changes at Weeks
28 and 52 will be assessed only for subjects at selected sites.
Valvular regurgitation as assessed in the 
echocardiogram will be rated absent, trace, mild, moderate, or severe for the aortic, mitral, and tricuspid valves; 
the rating will be absent or present for the pulmonic valve. The evaluations will be based on guidelines from the 
American Society of Echocardiography. Pulmonary artery pressure will be estimated from the TR jet velocity.

Analysis Sets

The Safety Analysis Set is the group of subjects who received at least 1 dose of study drug and had at least 
1 post dose safety assessment.

The Full Analysis Set (FAS) is the group of all randomized subjects regardless of adherence to study drug.

Per-Protocol Analysis Set (PP) is the group of all randomized subjects who are 80% or greater compliant 
with study medication, completed the study, have no major protocol deviations, have no violations of 
inclusion or exclusion criteria, and have BMI data at Baseline and Week 52.  The determination of subjects 
to be excluded from this population based on the above criteria and a list of major protocol violations will 
be included in the statistical analysis plan (SAP) and finalized before data base lock.

The PD Analysis Set is the group of subjects who had sufficient PD data to derive at least 1 PD parameter.

The PK Analysis Set is the group of all randomized subjects from whom at least 1 valid lorcaserin plasma 
concentration was obtained with associated documented dosing history.

The population PK/PD set is the group of randomized subjects with PK information and who have at least 
1 adequately documented measurement of BMI.
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, and the PP will be used as a 
supportive analysis.  Unless otherwise specified, a 2-sided α=0.05 significance level will be used in all efficacy 
analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change from baseline in 
BMI will be analyzed using analysis of covariance model (ANCOVA) with factors of treatment,  sex (male and 
female) as fixed effect, and the baseline age and BMI as covariates.  The missing values will be imputed using a 
pattern mixture model utilizing multiple imputation (MI) assuming the missing values are missing not at 
random (MNAR).  The missing values will be imputed at each visit using all available values including the 
retrieved measurement from the postdiscontinuation data.  The details of the analysis model and missing value 
imputation method will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis:  The same primary efficacy analyses described above will be repeated based on the PP.

Change from baseline in standardized BMI score (Z-score):  The same primary efficacy analyses described 
above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed and will be
described in the SAP.
Key Secondary Efficacy Analyses
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 5% BMI reduction at 
Page 219 of 897

Clinical Study Protocol
APD356-A001-403
Eisai
FINAL:  v8.0, 12Dec2017

Page 11 of 84
Week 52. The secondary efficacy endpoint will be analyzed only if the test for the primary efficacy endpoint is 
statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be analyzed using a logistic 
regression model with factors of treatment, sex (male and female), and baseline BMI as a covariate using FAS.  
Subjects with any missing assessment at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be analyzed using 
mixed effect model repeated measurement analysis (MMRM) and categorical variables will be analyzed using
the Cochran Mantel Haenszel test, Chi-square test, or logistic regression as appropriate.  Additional analysis 
may be performed as needed using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male and female), and 
race (American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or other Pacific 
Islander, or White) and age.  Additional subgroups may be explored, if deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and sensitivity analyses.
Pharmacokinetic Analyses
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using nonlinear mixed 
effects modeling. The effect of covariates such as baseline characteristics or demographics on PK will be 
explored. Derived exposure parameters such as the maximum observed concentration and the area under the 
concentration-time curve from time 0 to 24 hours at steady-state will be calculated from the final PK model 
using individual posterior estimates of the PK parameters and from dosing history. The PK analysis set will be 
used for this analysis.
Pharmacodynamic Analyses
Change from Baseline in BMI will be assessed as the PD endpoint.  The PD analysis set will be used for this 
analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% and ≥10% BMI 
reduction, and change in waist circumference from baseline) will also be assessed as part of the PD analysis.  
The PK/PD analysis set will be used for this analysis.
Pharmacokinetic/Pharmacodynamic Analyses
Population PK/PD modeling will be used to explore the relationship between lorcaserin plasma exposure and 
response, including but not limited to change in BMI from baseline and the probability of achieving at least a 
5% and at least a 10% change in BMI from baseline to Week 52.  Additionally, exposure-safety relationships 
for select safety parameters may be explored graphically depending on the data at the end of study.  Any 
emergent relationship may be modeled as appropriate.  Any parameters based on the study data may be 
considered for exploratory assessment for its relationship to PK.
Pharmacogenomic/Pharmacogenetic Analyses
Not applicable
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments including the incidence 
of AEs (including changes from baseline in physical examination), growth (CDC growth chart and bone age 
determined by x-ray of the hand), sexual maturation (Tanner Staging), out-of-normal-range laboratory safety 
test values, change from baseline in laboratory safety test values, ECGs, and vital sign measurements will be 
summarized by treatment group using descriptive statistics or frequency count as appropriate.  
Other Safety Analyses
In addition, cognition will be evaluated by the Leiter-3, depression will be evaluated by the PHQ-9, and suicidal 
ideation and behavior will be evaluated by the C-SSRS, and will also be summarized by treatment group using 
descriptive statistics or frequency count as appropriate. For echocardiographic assessments, the proportion of 
subjects who develop FDA-defined valvulopathy, the proportion of subjects who develop pulmonary

hypertension [pulmonary hypertension is defined when the subject’s systolic pulmonary artery pressure 
(SPAP) ≥40 mmHg evaluated by echocardiograph], and change from baseline in SPAP will be summarized by 
treatment group at Week 28 and Week 52 using descriptive statistics or frequency count as appropriate. (revised 
per Amendment 01)
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
Interim Analyses

Sample Size Rationale
The proposed sample size is based on the comparison of the primary efficacy endpoint, change in BMI from 
Baseline to Week 52 between the Belviq XR 20-mg treatment group and placebo group.  Assuming a SD of 
2.2 kg/m2 and a 40% dropout rate, a sample size of 260 subjects in a 1:1 ratio (n=130 in the Belviq XR 20-mg 
treatment group; n=130 in the placebo group) will have at least 80% power to detect a treatment difference of 
1 kg/m2 in BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at least a 5% 
BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, this sample of 260 subjects 
(130 subjects for Belviq XR 20 mg and 130 subjects for placebo) will also have greater than 78% power to 
detect an absolute difference of 20% between the Belviq XR 20-mg group and the placebo group, using a 
2-sided Chi-Square test with α=0.05.
The assumption used in the sample size calculation is based on the 
2 pivotal lorcaserin studies APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

INTRODUCTION
7.1
Indication
Obesity has become a global epidemic, causing a serious public health concern.  In the 
United States, the prevalence of obesity in adolescents ages 12 and 19 years has almost 
doubled over the past 2 decades.  The rate increased from 10.5% between 1988 and 1994 to 
20.5% between 2011 and 2012 (CDC/NCHS, 2013).  Obesity in adolescents, defined in the 
United States as greater than or equal to the 95th percentile in gender- and age-specific body 
mass index (BMI), continues to grow at an alarming rate in the United States and globally.  
Based on data (Wang and Lobstein, 2006) using various criteria for the definition of obesity 
that included more than 30 countries in Europe, North America, Asia, and the West Pacific, 
prevalence of obesity in these countries has also increased significantly, at a rate comparable 
to that in the United States.
Adolescent obesity has many negative implications for both the health and well-being of the 
individual as well as for society.  These include increased susceptibility to a host of diseases, 
chronic health disorders, psychological disorders, and premature death (Flegal, et al., 2005; 
Rofey, et al., 2009).  Increases in the prevalence of overweight and obese adolescents may 
result in a decrease in life expectancy for the 1st time in 200 years (Peeters, et al., 2003).
As a result, there is a significant impact on the cost of healthcare.  It is estimated that medical 
costs due to overweight adolescents are approximately $14 billion per year in the United 
States (Trasande and Chatterjee, 2009).  Obesity-related medical costs in general are
expected to rise significantly because today’s obese adolescents are likely to become 
tomorrow’s obese adults (Whitaker, et al., 1997).
Current approaches to weight management in adults include lifestyle modification, 
pharmacotherapy, and invasive bariatric procedures.  Lifestyle modification involves a 
combination of diet, exercise, and behavioral change, and is the preferred and essential 
strategy for weight management in obese and overweight individuals, including adolescents.  
Although lifestyle modification can be very efficacious in some patients, adherence to the 
prescribed regimens is often poor.  As such, lifestyle modification alone is often not adequate 
and the weight loss is often transient.  On the other hand, bariatric surgery and various other 
invasive procedures are generally reserved for the severely obese population. 
Pharmacotherapy can play a significant role in weight management programs, and is often 
combined with lifestyle modification to enhance weight loss beyond that which is normally 
achieved with diet and exercise alone.  Current pharmacotherapies offer the potential to 
significantly augment weight loss when combined with diet and exercise, but are rarely used 
for adolescents.
The current standard of care for treatment of obesity in adolescent subjects ranges from
behavioral therapy including lifestyle intervention to the rare use of pharmacotherapy in 
adolescents over 12 years of age (McGovern, et al, 2008; Spear, et al, 2007).  Xenical®
(orlistat) is currently the only product available for weight control in obese adolescent 
patients 12 to 16 years of age.  However, it is associated with gastrointestinal side effects

(Xenical PI. 2015), and the treatment effect of Xenical is modest. In a study that included 
539 obese adolescents with BMI above the 97th percentile, Xenical demonstrated a 0.86 BMI 
reduction relative to placebo after 52 weeks of treatment (-0.55 BMI in the Xenical treatment 
group versus +0.31 BMI in the placebo group) (FDA, 2003; Chanoine, et al, 2005).
Obtaining maximum retention in the study is a major goal in order to minimize missing data.  
A number of strategies have been used in prior adolescent weight loss studies may be used in 
the present study to help retain participants.  These include a highly trained and competent 
site staff, ample waiting area, readily available parking (at no cost), access to mass transit, 
and reminder and follow-up calls.  In addition, sites may utilize fun and interactive group 
sessions with games and hands-on nutrition and physical activity demonstrations, random 
raffle drawings, social events, birthday and holiday cards, and newsletters to further 
encourage subject retention.  Furthermore, we may make home visits for primary efficacy 
assessments of, as needed, to maximize data collection. By incorporating some of these 
retention strategies, we hope that we will maximize participant retention, which will help us 
cope with missing data.
7.1.1
APD356/Belviq (lorcaserin hydrochloride)
7.1.1.1
Mechanism of Action
Belviq is a selective serotonin 2c receptor agonist which was approved by the US Food and 
Drug Administration (FDA) on 27 Jun 2012 as an adjunct to a reduced-calorie diet and 
increased physical activity for chronic weight management in adult patients with a BMI of at 
least 30 kg/m2 (obese), or adult patients with a BMI greater than or equal to 27 kg/m2
(overweight) in the presence of at least 1 weight-related comorbid condition.
7.1.1.2
Clinical Experience with APD356/Belviq (lorcaserin hydrochloride)
The Phase 3 clinical evaluation of Belviq in studies of more than 7700 adult subjects, 
including 604 subjects with Type 2 diabetes mellitus, demonstrated clinically meaningful 
efficacy and a safety profile that includes minimal and easily managed risks.  In each of the 
individual studies and in the pooled efficacy analyses, the Belviq dose met the following 
prespecified endpoints:

A significantly greater proportion of adult subjects taking Belviq 10 mg twice per day 
(BID) (47%) lost at least 5% of baseline body weight at 52 weeks as compared to 
subjects taking placebo (23%).  A significantly greater proportion of subjects taking 
Belviq 10 mg BID (22.4%) lost at least 10% of baseline body weight at 1 year as 
compared to subjects taking placebo (8.7%). 

The mean weight loss at 1 year in adult subjects taking Belviq 10 mg BID (-5.8 kg) was 
significantly greater than that in subjects taking placebo (-2.5 kg).
An integrated evaluation of the data from the pediatric, adolescent, and adult subjects 
revealed that the relationship between lorcaserin area under the curve (AUC) and body 
weight in pediatric and adult subjects is consistent irrespective of the individual studies or 
age range of the study population. Irrespective of age, lorcaserin AUC values in the pediatric 
subjects with body weight of greater than 60 kg overlapped with the data observed from the

studies involving adult subjects, suggesting a fixed dose approach similar to adults can be 
used for adolescent subjects with body weight greater than 60 kg.
In adolescent obese populations, it is anticipated that Belviq XR will result in similar effects.
As part of FDA postmarketing requirements, this study is designed to characterize the 
efficacy and safety of Belviq XR in adolescent obese populations in the United States.  It is 
also intended to support an indication for chronic weight management for obese adolescents 
ages 12 to 17 years old. 
7.1.2
Study Rationale
There is no specific FDA guidance for the approval of a weight loss product for adolescents.  
In adults, the Division’s 2007 draft Guidance for Industry Developing Products for Weight 
Management indicate that the product needs to satisfy either of the following mean or 
categorical criteria after 1 year of treatment:

The difference in mean weight loss between the active-product and placebo-treated 
groups is at least 5% and the difference is statistically significant.

The proportion of subjects who lose at least 5% of baseline body weight in the 
active-product group is at least 35%, is approximately double the proportion of subjects 
in the placebo-treated group who lose at least 5% of baseline body weight, and the 
difference between groups is statistically significant.
FDA awarded a weight management indication for Belviq based on Phase 3 study results 
which achieved the categorical criteria. In a Phase 3 study, a significantly greater proportion 
of subjects taking Belviq (47%) lost at least 5% of baseline body weight at 1 year as 
compared to subjects taking a placebo (23%).  It is anticipated that a similar effect will be 
demonstrated in obese adolescents, where weight loss will be assessed using BMI
measurements to account for growth. In this study, the objective is to demonstrate that BMI
reduction will be achieved during 52 weeks of treatment with Belviq XR 20 mg administered 
once daily (QD) compared to placebo in obese adolescents.
In the Phase 3 orlistat study in obese adolescents mentioned above, the proportion of subjects 
who lost at least 5% body weight is relatively low. At the end of the study at Week 52, only 
26.5% of the subjects achieved a 5% or greater BMI reduction compared to 15.7% in the 
placebo group. The placebo-corrected BMI reduction was about 0.86 kg/m2.  
There are limited trials for weight reduction in the adolescent population, ages 12 to 17 years
(Peirson, et al, 2015).  Thirty-one studies (29 behavioral, 2 pharmacological and behavioral) 
were included in a meta-analysis of randomized studies conducted in primary care centers in 
overweight and obese children and youth ages 2 to 18 years using behavioral (diet, exercise,
and lifestyle) and pharmacological interventions and providing 6-month postbaseline BMI or 
prevalence of overweight or obesity. Both interventions showed a significant effect on BMI 
in favor of treatment (behavioral: 
standardized mean difference [SMD] -0.54, 
95% confidence interval [CI]
-0.73, -0.36; orlistat plus behavioral: 
SMD -0.43, 
95% CI -0.60, -0.25). The studies reported no significant difference between groups in the 
likelihood of reduced prevalence of overweight or overweight and obese. A great deal of

variation was noted across efficacious interventions.
In conclusion, this meta-analysis 
demonstrated low-quality evidence that behavioral treatments alone are associated with a 
smaller effect in terms of reduced BMI compared with the effect shown by combined 
behavioral and pharmacological interventions. This may be because the effect size in the 
randomized, double blind, placebo controlled, phase 3 orlistat study in adolescents was 
relatively low and there was a lack of maintenance effect. These subjects started to regain 
their BMI after 6 months of treatment. At end of the study, only 26.5% of subjects achieved 
a 5% or greater BMI reduction compared to 15.7% in placebo group. In a sibutramine 
Phase 3 study in obese adolescents, a substantially higher proportion of subjects (69%) 
treated with sibutramine achieved at least a 5% BMI reduction compared to 21% of subjects 
in the placebo group. In addition, sibutramine resulted in a substantial reduction in mean 
BMI (between-group difference, 2.9 kg/m2) and mean weight (between-group difference, 
8.4 kg) compared to placebo (Berkowitz, et al, 2006).  Unlike the weight loss effect of Belviq
in adults and sibutramine in adolescents, subjects in the orlistat study started to increase their 
BMI after 6 months of treatment.
In this study, it is assumed that treatment with Belviq XR 20 mg will lead to a BMI reduction
of more than 1 kg/m2, and a higher proportion of subjects will achieve more than a 5% and 
10% BMI reduction compared to placebo.  A between-group difference of 24% is the basis 
for the conservative assumption of a 20% effect size in the current study.
In addition, the total sample size of 260 subjects will be adequate to assess safety and 
exposure based on previous adolescent studies with weight management products (orlistat 
sibutramine, and liraglutide 3 mg) (FDA, 2003; Chanoine, et al., 2005; Berkowitz, et al,
2006; CT.gov NCT02918279) and other metabolic or dyslipidemia medication products
(ezetimibe, simvastatin) (FDA, 2007).  (revised per Amendment 02)

INVESTIGATIONAL PLAN
9.1
Overall Study Design and Plan
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in 
obese adolescents ages 12 to 17 years.  Approximately 260 subjects will be randomized in a 
1:1 ratio to Belviq XR 20 mg QD (130 subjects) and placebo (130 subjects).  Subjects will be 
stratified by sex.  Subjects will receive Belviq XR 20 mg or matched placebo QD in a 1:1 
ratio for up to 52 weeks. A recruitment plan will be developled to ensure at least 20% of 
younger subjects (12 to 13 years of age) are enrolled in the study.  Throughout the duration 
of the study, subjects will be encouraged to adhere to a lifestyle modification program that 
includes a standardized, age-appropriate diet and exercise counseling (see Appendix 2).  
(revised per Amendments 02 and 03)
The study will consist of 2 phases:
Prerandomization and Randomization.  The 
Prerandomization Phase will last up to 30 days and consists of 1 visit during which subjects 
will be screened for eligibility.  The Randomization Phase consists of a Treatment Period and 
a Follow-Up Period.  The Treatment Period will last for a maximum of 52 weeks, with visits 
at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52; the Follow-Up Period will extend from the 
End of Treatment (EOT) visit to the End of Study (EOS) visit.
Subjects who screen fail can be rescreened only once after 30 days.  All subjects will 
continue in the study until the 52-week evaluation is completed.  Subjects who discontinue 
treatment prematurely will be followed up until study completion.  All attempts will be made 
to capture height and weight in all subjects whether or not they are still on study drug at the 
end of the study.  (revised per Amendment 03)
Study sites will be selected to ensure adequate representation of adolescents of ethinic and 
racial minorities.  (revised per Amendment 03)
A Data Monitoring Committee (DMC) will be established to monitor and conduct periodic 
safety review of unblinded data. DMC members will be chosen based on their expertise in 
evaluating these clinical events. A separate DMC charter will be established.  (revised per 
Amendment 03)
9.1.1
Prerandomization Phase
Screening will occur during the Prerandomization Phase at Visit 1.
9.1.1.1
Screening Period
The purpose of the Screening Period is to obtain the informed consent and assent and to 
establish protocol eligibility.  Procedures to be followed when obtaining informed consent 
are detailed in Section 5.3.  Careful initial screening is important in the recruitment of 
families who both fully understand the requirements of this 1 year, randomized, controlled 
trial and are truly interested in participation.  Interested caregivers and adolescents will be 
screened by phone to assess preliminary entry criteria.  Candidates will be given a brief

description of the program and general study requirements, with an adolescent and a 
caregiver who is willing to participate.  If preliminary entry criteria are met, adolescents and 
their caregivers will be invited to an initial in-clinic meeting to further discuss the study.  A 
complete description of the study including assessments, the number of visits, the lifestyle 
program, the fact that the adolescent would be taking either the study drug or a placebo, the
duration of the study, and the necessity of having an adolescent wishing to participate as well 
as a participating caregiver will be described.  Consent and assent will be obtained and copies 
of the signed forms will be provided to families.  The importance of the study and its 
scientific merit will be discussed.  Ineligible adolescents will be referred to local weight 
management resources.  Screening period assessments and timing thereof are shown in 
Section 9.5.2.

Discussion of Study Design, Including Choice of Control Groups
The proposed dose and dosing frequency of Belviq XR in this study is 20 mg QD.  The PK 
parameters of a single 10-mg dose of Belviq were evaluated in healthy, adolescent obese 
subjects in Study APD356-025.  Overall, the PK parameters of Belviq and its main 
metabolites, M1 and M5, were similar to those in adults.  Following a single, oral 
administration of Belviq 10 mg to a total of 8 healthy adolescent (ages 12 to 17 years old) 
obese subjects, the mean maximum concentration observed and the area under the 
concentration-time curve from time zero to infinity (AUC(0-inf)) were 36.5 ng/mL and 
464 hr×ng/mL, respectively.  The mean Belviq terminal phase half-life was 9.70 hours, 
similar to that observed in adults, thus supporting a similar dosing frequency (QD) in 
adolescent subjects.
Additionally, a single dose PK study in 8 healthy obese pediatric subjects ages 6 to 11 years 
of age was performed. The PK analysis after a single 10-mg dose of lorcaserin revealed that 
the lorcaserin AUC(0-inf) values tended to increase with decreasing body weight and age.
However, the body weight normalized AUC(0-inf) values were similar across the age groups, 
therefore the data indicated no effect of age on the lorcaserin PK. Integrated assessment of 
the PK versus body weight relationship, pooling the data from pediatric and adult subjects 
from previous studies, suggested that the lorcaserin area under the curve values for subjects 
with body weight of at least 60 kg overlapped with the area under the curve values from 
adolescents and adults. Therefore, no dose adjustment relative to adults and adolescents is 
deemed necessary for pediatric or adolescent subjects with a body weight of at least 60 kg.
Based on CDC growth charts, the likelihood of subjects who are older than 12 years of age 
having a body weight of less than 60 kg is very low; therefore, the current study as designed

to enroll subjects between 12 to 17 years of age with body weight at least 60 kg, will cover
majority of the population of interest.  The targeted study population comprises 260 obese 
adolescents 12 to 17 years of age, with a body weight at least 60 kg.  (revised per 
Amendment 02)
Obese adolescents will be identified using gender- and age-specific BMI measurement.  
Obesity in adolescents is defined by US Expert committee recommendations as BMI in or 
above the 95th percentile (Barlow, 2007).
Randomization will be used in this study to avoid bias in the assignment of subjects to 
treatment, to increase the likelihood that known and unknown subject attributes 
(eg, demographics, baseline characteristics) are balanced across treatment groups, and to 
ensure the validity of statistical comparisons across treatment groups.  Blinding to treatment 
will be used to reduce potential bias during data collection and evaluation of endpoints.
9.3
Selection of Study Population
Approximately 500 subjects will be screened to ensure that 260 subjects will be randomized.  
(revised per Amendment 02)
Subjects who do not meet all inclusion criteria or do meet any exclusion criteria will not be 
eligible to receive study drug.
Subjects who screen fail can be re-screened immediately 
without repeating the screening echocardiogram for up to 90 days after the previous 
echocardiogram.  All other screening assessments must be repeated when a subject is re-
screened.  Subjects that re-screen more than 90 days after the previous echocardiogram must 
repeat all screening assessments including the screening echocardiogram.  (revised per 
Amendment 03)
9.3.1
Inclusion Criteria
Subjects must meet all of the following criteria to be included in this study:
1. Healthy male or female adolescents, ages 12 to 17 years old (inclusive) at Screening, with 
an initial BMI that is greater than or equal to the United States (US)-weighted mean of 
the 95th percentile based on age and sex with a body weight greater than 60 kg.  Subjects 
with T2DM may have a pre-existing or new diagnosis of T2DM.  
Subjects with pre-existing T2DM should have prior documentation consistent with the 
diagnosis and/or be on active pharmacotherapy for T2DM.  
Subjects with a new diagnosis of T2DM (ie, diagnosed at Screening) should be based on 
the 2016 American Diabetes Association (ADA) guidelines.  The diagnostic criteria are 
met if a subject has unequivocal hyperglycemia (random plasma glucose ≥200 mg/dL 
(11.1 mmol/L) with classic symptoms of hyperglycemia or hyperglycemic crisis) OR any 
of the following criteria are observed and then confirmed:
o
HbA1c ≥6.5% 
o
fasting plasma glucose (FPG) ≥126 mg/dL (7.0 mmol/L)

o
2-hour plasma glucose ≥200 mg/dL (11.1 mmol/L) by an oral glucose tolerance 
test (OGTT)
All T2DM subjects must have an HbA1c <10% at Screening.  If subjects are being or 
need to be treated with antidiabetic agents, the T2DM treatment regimen must be stable 
for at least 3 months before randomization.  A single rescreen is allowed following 
stabilization.  Stable control refers to minimal dose changes to existing medications for 
glycemic control and no medications being initiated for glycemic control in the 3 months 
before Randomization.  Minimal changes are defined as a change without any change in 
dose frequency, no add-on or discontinuation of other antidiabetic agents, and the subject 
has not been hospitalized due to hypo- or hyperglycemic events.  (revised per 
Amendment 03)
2. Subjects and their families are not planning to move away from the area for the duration 
of the study
3. Able and willing to comply with all aspects of the study, including a standardized,
reduced-calorie diet and an age-appropriate, increased physical activity program
4. Considered in stable health in the opinion of the investigator
5. Caregivers or guardians meet the following requirements:
a.
Able and willing to support and supervise study participation in the opinion of the 
investigator, including consideration of any existing physical, medical, or mental 
condition that prevents compliance with the protocol
b. Able and willing to personally comply with and execute all aspects of the study 
requirements for the caregivers or guardians
9.3.2
Exclusion Criteria
Subjects who meet any of the following criteria will be excluded from this study:

mean gradient >25 mm Hg, and aortic valve area [AVA] <1.5 cm2; MS: mean 
gradient >5 mm Hg and mitral valve area [MVA] <1.5 cm2)

Systolic pulmonary artery pressure
(SPAP) >40 mm Hg (and/or tricuspid 
regurgitation (TR) jet velocity >2.9 m/s)
-
In cases where an actual SPAP value is not measurable due to lack of adequate 
TR jet, the pulmonary flow acceleration time measured at the right ventricular 
outflow tract (RVOTAT), will be used to assess eligibility. Patients with a

All packaging and labeling will be performed according to Good Manufacturing Practices 
and GCP guidelines.
Study drug must be stored as instructed on the study drug label and in accordance with the
DEA Regulations for Schedule IV Controlled Drugs (US sites). Study drug must be kept
in a secure location as required by DEA regulations and carefully stored at the study site
within its original container.
The investigator (or pharmacist, as appropriate) must maintain records of the delivery of
the study drug to the study site, the inventory at the site, use for each subject, and return of
the study drug to a delegate of the sponsor. Total study site accountability will be conducted
at the end of the study and the investigator must explain any discrepancies.
A Drug Dispensing Log must be kept current and should contain at least the following 
information:

Identification (subject ID number and initials) of the subject to whom the study drug was 
dispensed
•
The dates and unique kit or carton identifiers for dispensed study drug
•
Initial inventory on receipt of drug at the site
•
Final inventory on completion of the study
All records and inventory must be available for inspection by the clinical study
monitor.
9.4.2.4
Storage Conditions
Where applicable, investigational product will be stored in accordance with the DEA 
Regulations for Scheduled III to V Drugs and labeled storage conditions.  Temperature 
monitoring is required at the storage location to ensure that the study drug is maintained 
within an established temperature range.  The investigator or designee is responsible for 
ensuring that the temperature is monitored throughout the total duration of the study and that 
records are maintained; the temperature should be monitored continuously by using either an 
in-house validated data acquisition system, a mechanical recording device, such as a 
calibrated chart recorder, or by manual means, such that minimum and maximum 
thermometric values over a specific time period can be recorded and retrieved as required.
9.4.3
Method of Assigning Subjects to Treatment Groups
Subjects will be assigned to treatments based on a computer-generated randomization 
scheme that will be reviewed and approved by an independent statistician.  The 
randomization scheme and identification for each subject will be included in the final clinical 
study report for this study.
Subjects will be centrally stratified by sex (male and female).  Within each stratum, subjects 
will be randomized to receive either Belviq XR 20 mg or placebo QD in a 1:1 ratio.

Randomization will be performed centrally by an interactive voice or web response system 
(IxRS).  The IxRS or clinical supply vendor will generate the randomized identification
numbers to be included on study packaging.  Upon signature of the ICF, the investigator or 
designee will access the IxRS to register the subject information.  At Randomization, the 
IxRS will assign each subject a unique randomization number.  At each subsequent visit 
during the Treatment Period and Follow-Up Period, the investigator or designee will access 
IxRS to obtain dispensing information and to register the subject’s visit.
9.4.4
Selection and Timing of Dose for Each Subject
Subjects should take the study medication once daily at approximately the same time of 
every day, and be encouraged to take the study medication with an adequate amount of water 
(8 oz. or 240 mL).  For information on dosing on visits associated with PK sampling, see 
Section 9.5.1.4.1.  (revised per Amendment 03)
9.4.5
Blinding
During the Randomization Phase, subjects and all personnel involved with the conduct and 
interpretation of the study, including investigators, site personnel, and sponsor staff will be 
blinded to the treatment codes.  Randomization data will be kept strictly confidential, filed 
securely by an appropriate group with the sponsor or CRO, and accessible only to authorized 
persons (eg, Eisai Global Safety) until the time of unblinding, per the SOP.
A master list of all treatments and the subject numbers associated with them will be 
maintained in a sealed envelope by the clinical supply vendor, the IxRS vendor, and the 
sponsor.  In the event that emergency conditions require knowledge of the study treatment 
given, the blind may be broken via the code breaker facility within the IxRS.  Emergency 
procedures for revealing drug codes are given in Section 9.5.4.5.  If possible, before breaking 
the blind, the investigator should consult with the sponsor or designee to ascertain the 
necessity of breaking the code.
9.4.6
Prior and Concomitant Therapy
Any medication (including OTC medications) or therapy administered to the subject during 
the study (starting at the date of informed consent) will be recorded on the Prior and
Concomitant Medication Case Report Form (CRF) or Non-Pharmacological Procedures 
CRF.  The investigator will record on the Adverse Event CRF any AE for which the 
concomitant medication/therapy was administered. If the concomitant medication/therapy is 
being administered for a medical condition present at the time of entry into the study, the 
investigator will record the medical condition on the Medical History and Current Medical 
Condition CRF.

The following concomitant medication guidelines/restrictions will apply:

Medications for the treatment of hypertension, dyslipidemia, or diabetes may be 
started, discontinued, or adjusted during the study according to local standards of care 
if, in the judgment of the investigator or the subject’s physician, such a change is 
medically indicated.

For diabetic subjects treated with sulfonylureas, insulin (note that subjects should not 
be enrolled as indicated in exclusion criteria), or other antidiabetic agents with 
hypoglycemic risk, the risk of hypoglycemic events may be higher if the subjects 
experience rapid and significant weight loss (more than 10% weight reduction than at 
the previous visit).  It is recommended that the physician advise the subject to 
monitor their blood glucose more frequently and adjust their antidiabetic medications 
and diet accordingly.


The antihyperglycemic medication dose would be considered for reduction in the 
event of 1 documented and otherwise unexplained hypoglycemic event (blood 
glucose concentration <65 mg/dL) or 2 undocumented and otherwise unexplained 
suspected hypoglycemic events between any 2 scheduled visits.   For subjects on 
more than 1 antihyperglycemic medication, it is recommended to reduce insulin first 
(if applicable), then the oral and/or other injectable antidiabetic agents.  If the 
previous criteria are met again following dose reduction, further dose reductions or 
cessation of 1 or more anti-hyperglycemic agents, are suggested.  See Section 9.5.4.2
for the definition and reporting of hypoglycemic events. 
To minimize the risk of cardiac valve toxicity, subjects must not initiate use of agents that 
have documented correlation with increased incidence of valvulopathy and/or PH (eg, 
pergolide, ergotamine, methysergide, or cabergoline) during the study.  (revised per 
Amendment 01)  If any of the above agents are clinically warranted, and subjects initiate any 
of these agents, lorcaserin HCl should be discontinued but can be restarted on lorcaserin HCl 
after being off the medications above for 1 month.  Otherwise, the study medication should 
not be restarted, but the subject should continue all study visits.  (revised per Amendment 03)
9.4.7
Treatment Compliance
Records of treatment compliance for each subject will be kept during the study.  Subjects will 
be asked to bring their study drug bottles to each visit.  The CRAs will review treatment 
compliance during site visits and at the completion of the study.  (revised per 
Amendment 03)
Per visit schedule, subjects will return unused study drug and be given a new supply; pill 
counts will be made by study staff on returned medication.

Efficacy Assessments

Body weight and height: will be measured using a standard stadiometer method (Lohman 
T, et al, 1988) to calculate changes in BMI.
Body weight will be measured in the 
morning after at least 8 hours of fasting and voiding using a calibrated scale and 
standardized instructions for clothing (ie, a hospital gown). Weight will be measured to 
the nearest 0.1 kg. Height will be measured in triplicate utilizing a stadiometer with a 
standardized process (eg, subjects should not be wearing shoes). Height must be 
measured to the nearest 0.1 cm.  BMI will then be used to calculate the proportion (%) of 
subjects achieving at least a 5% and at least a 10% BMI reduction.  (revised per 
Amendment 03)

9.5.1.5.1
ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered an investigational product.  An AE does not necessarily have a causal

relationship with the medicinal product.  For this study, the study drug is Belviq XR
(lorcaserin hydrochloride).
The criteria for identifying AEs in this study are:
•
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or 
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE)
•
Any new disease or exacerbation of an existing disease 
•
Any deterioration in non-protocol-required measurements of a laboratory value or other 
clinical test (eg, ECG, x-ray) that results in symptoms, a change in treatment, or 
discontinuation of study drug
•
Recurrence of an intermittent medical condition (eg, headache) not present pretreatment 
(Baseline)
•
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of study drug, or withholding 
of study drug, whether prescribed in the protocol or not.
All AEs observed during the study will be reported on the Adverse Event CRF.  All AEs, 
regardless of relationship to study drug or procedure, should be collected beginning from the 
time the subject signs the study ICF through the last visit in the Treatment Phase.  Subjects 
who fail screening primarily due to AE(s) must have the AE(s) leading to screen failure 
reported on the Screening Disposition CRF.  SAEs will be collected for 28 days after the last 
dose.
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute 
an AE.  Medical and scientific judgment should be exercised in deciding whether an isolated 
laboratory abnormality should be classified as an AE.  Any laboratory abnormality 
considered to constitute an AE should be reported on the Adverse Event CRF. 
Abnormal ECG (corrected QT interval [QTc]) results, if not otherwise considered part of a 
clinical symptom that is being reported as an AE, should be considered an AE if the QTc 
interval is greater than 450 msec and there is an increase of more than 60 msec from baseline.  
Any ECG abnormality that the investigator considers as an AE should be reported as such.
At each visit, the investigator should actively assess as to whether any of the following 
adverse events have occurred during the interval since the last visit:
•
Serotonin syndrome and signs or symptoms of serotonergism
•
Signs or symptoms of valvular heart disease or pulmonary hypertension, including 
dyspnea, dependent edema, congestive heart failure, or a new cardiac murmur

•
Impairments in attention and memory, and confusion, somnolence, and fatigue
•
Psychiatric disorders
•
Hypoglycemia in subjects with diabetes on concomitant anti-diabetes medications (using 
ADA definitions)
•
Priapism and hyperprolactinemia signs and symptoms should be recorded at each visit 
and whenever reported
•
Hypersensitivity reactions
Any such events should be recorded as adverse events.  Serotonin syndrome, valvular heart 
disease, pulmonary hypertension, and priapism should always be reported as serious adverse 
events (SAEs) (See Section 9.5.1.5.2 for a complete list of adverse events that should always 
be considered as Serious).  (revised per Amendment 03)
Events of hypoglycemia in subjects with diabetes on concomitant anti-diabetes medication 
should be captured as per Section 9.5.2.  Severe symptomatic events of hypoglycemia should 
always be reported as an SAE as per Section 9.5.1.5.2.  (revised per Amendment 03)
It is the responsibility of the investigator to review the results of the Leiter-3, C-SSRS, and 
PHQ-9 for all subjects and determine if any result constitutes an AE.  Medical and scientific 
judgment should be exercised in deciding whether an isolated suicidality rating scale 
response should be classified as an AE (see Section 9.5.1.5.10 for a description of the 
C-SSRS).  (revised per Amendment 01)
All AEs must be monitored until symptom resolution, or until the condition stabalizes.  
(revised per Amendment 03)
Every effort must be made by the investigator to categorize each AE according to its 
severity and its relationship to the study treatment.
Assessing Severity of Adverse Events
Adverse events will be graded on a 3-point scale (mild, moderate, severe) and reported in the 
detail indicated on the CRF.  The definitions are as follows:
Mild
Discomfort noticed, but no disruption of normal daily activity
Moderate Discomfort sufficient to reduce or affect normal daily activity
Severe
Incapacitating, with inability to work or to perform normal daily activity
The criteria for assessing severity are different than those used for seriousness (see
Section 9.5.1.5.2 for the definition of an SAE).
Assessing Relationship to Study Treatment
Items to be considered when assessing the relationship of an AE to the study treatment are:

•
Temporal relationship of the onset of the event to the initiation of the study treatment
•
The course of the event, especially the effect of discontinuation of study treatment or 
reintroduction of study treatment, as applicable
•
Whether the event is known to be associated with the study treatment or with other 
similar treatments
•
The presence of risk factors in the study subject known to increase the occurrence of the 
event
•
The presence of nonstudy, treatment-related factors that are known to be associated with 
the occurrence of the event
Classification of Causality
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question:
Is there a reasonable possibility that the study drug caused the AE?
Yes (related)
A causal relationship between the study drug and the AE is a reasonable 
possibility.
No (not related) A causal relationship between the study drug and the AE is not a 
reasonable possibility.
9.5.1.5.2
SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An SAE is any untoward medical occurrence that at any dose:
•
Results in death
•
Is life-threatening (ie, the subject was at immediate risk of death from the AE as it 
occurred; this does not include an event that, had it occurred in a more severe form or 
was allowed to continue, might have caused death)
•
Requires inpatient hospitalization or prolongation of existing hospitalization
•
Results in persistent or significant disability/incapacity
•
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug)
Other important medical events that may not be immediately life-threatening or result in 
death or hospitalization but, when based on appropriate medical judgment, may jeopardize 
the subject or may require intervention to prevent one of the outcomes in the definition of 
SAE listed above should also be considered SAEs.  Medical and scientific judgment should 
be exercised in deciding whether expedited reporting is appropriate in such situations. 
For this study, the following events should always be considered serious and reported as an 
important medical event if it does not meet other serious criteria:

•
Serotonin syndrome (must have at least 1 of the following: 
Spontaneous clonus; 
Inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus)
•
Psychosis
•
Suicidal behavior
•
Priapism
•
New onset valvular heart disease
•
New onset pulmonary hypertension
•
Malignant neoplasms (revised per Amendment 03)
•
Fibroadenomas of the breast or ductal carcinoma in situ
•
Severe symptomatic hypoglycemia (revised per Amendment 03)
In addition to the above, events associated with special situations include pregnancy or 
exposure to study drug through breastfeeding; AEs associated with study drug overdose, 
misuse, abuse, or medication error.  These events associated with special situations are to be 
captured using the SAE procedures but are to be considered as SAEs only if they meet 1 of 
the above criteria.  All AEs associated with special situations are to be reported on the CRF 
whether or not they meet the criteria for SAEs.  
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization.
The following hospitalizations are not considered to be SAEs because there is no “AE” (ie, 
there is no untoward medical occurrence) associated with the hospitalization:
•
Hospitalizations for respite care
•
Planned hospitalizations required by the protocol  
•
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed after study drug administration)
•
Hospitalization for administration of study drug or insertion of access for administration 
of study drug
•
Hospitalization for routine maintenance of a device (eg, battery replacement) that was in 
place before study entry

9.5.1.5.10 OTHER SAFETY ASSESSMENTS
Leiter-3
The Leiter International Performance Scale–Third Edition (Leiter-3) is widely used 
non verbal measure of intelligence, memory, and attention in those between the ages of 3 and 
75 years. 
The Attention/Memory Battery consists of 5 subtests: 2 measure nonverbal 
attention; 2 measure memory; and 1 measures cognitive interference (nonverbal Stroop test). 
These subtests are combined to produce a Memory and Processing Speed composite scores, 
normalized to a mean of 100 and standard deviation of 15. The Leiter-3 will be used to 
assess lorcaserin effects on cognition, specifically, attention and memory. In addition, signs 
and symptoms of cognition-related AEs, including impairments in attention, memory, and 
adverse effects on schoolwork will be captured in the eCRF. (revised per Amendment 01)
PHQ-9
The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and 
measuring the severity of depression:

The PHQ-9 incorporates Diagnostic and Statistical Manual of Mental Disorders, 4th 
Edition (DSM-IV) depression diagnostic criteria with other leading major depressive 
symptoms into a brief self-report tool.

The tool rates the frequency of the symptoms which factors into the scoring severity 
index.

Question 9 on the PHQ-9 screens for the presence and duration of suicide ideation.

A follow-up, non-scored question on the PHQ-9 assigns weight to the degree to which 
depressive problems have affected the patient's level of function. 
C-SSRS
The C-SSRS collects information pertinent to suicidal ideation and actions.  It consists of a 
Baseline version which will be administered at baseline and a Since Last Visit version which 
will be administered at the remaining visits.  C-SSRS will be used to assess signal of 
depression and suicidal ideation or behavior. Qualified personnel must evaluate positive 
responses on the C-SSRS and take appropriate action as detailed in the training and

Reporting of Serious Adverse Events, Pregnancy, and Events Associated 
with Special Situations
9.5.4.1
Reporting of Serious Adverse Events
All SAEs, regardless of their relationship to study treatment, must be reported on a 
completed SAE form by email or fax as soon as possible but no later than 1 business 
day from the date the investigator becomes aware of the event.
SAEs, regardless of causality assessment, must be collected through the through the last visit
and for 28 days after the subject’s last dose.  All SAEs must be followed to resolution or, if 
resolution is unlikely, to stabilization.  Any SAE judged by the investigator to be related to 
the study treatment or any protocol-required procedure should be reported to the sponsor 
regardless of the length of time that has passed since study completion.
The detailed contact information for reporting of SAEs is provided in the Investigator Study 
File.
For urgent safety issues, please ensure all appropriate medical care is administered to the 
subject and contact the appropriate study team member listed in the Investigator Study File.
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report.  This includes the investigator’s assessment of causality.
Any follow-up information received on SAEs should be forwarded within 1 business day of 
its receipt.  If the follow-up information changes the investigator’s assessment of causality, 
this should also be noted on the follow-up SAE form.
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested by 
the sponsor.
The investigator must notify his/her IRB/IEC of the occurrence of the SAE, in writing, if 
required by their institution.  A copy of this communication must be forwarded to the sponsor 
to be filed in the sponsor’s Trial Master File.
9.5.4.2
Reporting of Pregnancy and Exposure to Study Drug through Breastfeeding
Any pregnancy in which the estimated date of conception is either before the last visit or 
within 28 days of last study treatment or any exposure to study drug through breastfeeding 
during study treatment or within 28 days of last study treatment must be reported.
If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, this 
should be reported regardless of the length of time that has passed since the exposure to study 
treatment.

A congenital anomaly, death during perinatal period, an induced abortion, or a spontaneous 
abortion are considered to be an SAE and should be reported in the same time frame and in 
the same format as all other SAEs (see Section 9.5.4.1).
Pregnancies or exposure to study drug through breastfeeding must be reported by fax or 
email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy.  The contact information for the reporting of pregnancies 
and exposure to study drug through breastfeeding is provided in the Investigator Study File.  
The Pregnancy Report Form must be used for reporting.  All pregnancies must be followed to 
outcome.  The outcome of the pregnancy must be reported as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the outcome.
A subject who becomes pregnant must be withdrawn from the study. 
9.5.4.3
Reporting of Events Association with Special Situations
9.5.4.3.1
REPORTING OF ADVERSE EVENTS ASSOCIATED WITH STUDY DRUG OVERDOSE,
MISUSE, ABUSE, OR MEDICATION ERROR
Adverse events associated with study drug overdose, misuse, abuse, and medication error 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication error are defined as follows:
Overdose
Accidental or intentional use of the study drug in an amount higher
than the protocol-defined dose
Misuse
Intentional and inappropriate use of study drug not in accordance with 
the protocol or authorized dose, route of administration, or 
indication(s) or use of prescription-only study drug without a 
prescription
Abuse
Sporadic or persistent intentional excessive use of study drug 
accompanied by harmful physical or psychological effects
Medication error
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of the 
healthcare professional, subject, or consumer.  Such events may be 
related to professional practice, healthcare products, occupational 
exposure, procedures, or
systems,
including prescribing,
order 
communication,
product
labeling, 
packaging, 
nomenclature,
compounding,
dispensing,
distribution,
administration, education,
monitoring, or use.
All AEs associated with overdose, misuse, abuse, or medication error should be captured on 
the Adverse Event CRF and also reported using the procedures detailed in Section 9.5.4.1
even if the AEs do not meet serious criteria.  Abuse is always to be captured as an AE.  If the 
AE associated with an overdose, misuse, abuse, or medication error does not meet serious

Page 60 of 84
criteria, it must still be reported using the SAE form and in an expedited manner but should 
be noted as nonserious on the SAE form and the Adverse Event CRF.
9.5.4.3.2
REPORTING OF STUDY-SPECIFIC EVENTS
Study-specific events (listed below) should always be considered as serious important 
medical events and be entered on the Adverse Event CRF and reported using the procedures 
detailed in Reporting of Serious Adverse Events (Section 9.5.4.1), even if the study-specific 
event does not meet other serious criteria.  

Serotonin syndrome
Must have at least 1 of the following: 
spontaneous clonus; 
inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus

Psychosis

Suicidal behavior 

Priapism

New onset of valvular heart disease

New onset pulmonary hypertension

Malignant neoplasms (revised per Amendment 03)

Fibroadenomas of the breast or ductal carcinoma in situ


Severe symptomatic hypoglycemia (revised per Amendment 03)
Subject-reported episodes of hypoglycemia or decreased blood sugar should be captured on 
the eCRF according to the following guidelines:

Psuedo-hypoglycemia:  An event during which the person with diabetes reports any of 
the typical symptoms of hypoglycemia and interprets those as indicative of hypoglycemia 
with a measured plasma glucose concentration >70 mg/dL (>3.9 mmol/L) but 
approaching that level.  (revised per Amendment 03)

Probable symptomatic hypoglycemia:  An event during which symptoms typical of 
hypoglycemia are not accompanied by a plasma glucose determination but that was 
presumably caused by a plasma glucose concentration ≤ 70 mg/dL (≤ 3.9 mmol/L)
(revised per Amendment 03)

Asymptomatic hypoglycemia: 
An event not accompanied by typical symptoms of 
hypoglycemia but with a measured plasma glucose concentration ≤ 70 mg/dL (≤ 
3.9 mmol/L) (revised per Amendment 03)

Documented symptomatic hypoglycemia: An event during which typical hypoglycemia 
symptoms are accompanied by a measured plasma glucose ≤70 mg/dL (≤3.9 mmol/L) 
(revised per Amendment 03)


Severe hypoglycemia: 
An event requiring assistance of another person to actively 
administer carbohydrate, glucagon or other resuscitation actions. Plasma glucose
measurements may not be available during such an event, but neurological recovery 
attributable to the restoration of plasma glucose to normal is considered sufficient 
evidence that the event was induced by a low plasma glucose concentration (revised per 
Amendment 03)
See Section 9.4.6 (Prior and Concomitant Therapy) for directions on the recommendations 
for possible adjustment to antihyperglycemic medication doses in response to reported 
episodes of hypoglycemia.  (revised per Amendment 03)
9.5.4.4
Expedited Reporting
The sponsor must inform investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (ie, within 
specific time frames).  For this reason, it is imperative that sites provide complete SAE 
information in the manner described above.
9.5.4.5
Breaking the Blind
In the case of a medical emergency where the appropriate treatment of the subject requires 
knowledge of the study treatment given, the investigator may break the randomization code 
for an individual subject.  In all such cases, the AE necessitating the emergency blind break 
will be handled as an SAE in accordance with the procedures indicated above.  Any broken 
code will be clearly justified and documented.  The medical monitor must be notified 
immediately of the blind break.
9.5.4.6
Regulatory Reporting of Adverse Events
Adverse events will be reported by the sponsor or a third party acting on behalf of the 
sponsor to regulatory authorities in compliance with local and regional law and established 
guidance.  The format of these reports will be dictated by the local and regional 
requirements.
9.5.5
Completion/Discontinuation of Subjects
The investigator may withdraw the subject from the study at any time for safety or 
administrative reasons.  A subject may elect to discontinue the study at any time for any 
reason.  All subjects will continue in the study until the 52-week evaluation is completed.  
Subjects who discontinue study drug prematurely will continue to be evaluated on for all 
study assessments until study completion.  All attempts will be made to capture height and 
weight in all subjects whether or not they are still on IP at the end of the study.  All subjects 
who discontinue the study are to complete the study’s early discontinuation procedures 
indicated in the Schedule of Procedures/Assessments Table 2). (revised per Amendment 03)
The investigator will promptly explain to the subject involved that the study will be 
discontinued for that subject and provide appropriate medical treatment and other necessary 
measures for the subject.  A subject who has ceased to return for visits will be contacted by

mail, phone, or other means to gather information such as the reason for failure to return, the 
status of treatment compliance, the presence or absence of AEs, and clinical courses of signs 
and symptoms.
Subjects who discontinue early from the study will be discontinued for 1 of these primary 
reasons: AE(s), lost to follow-up, subject choice, withdrawal of consent, pregnancy, study 
terminated by sponsor, or other.  In addition to the primary reason, the subject may indicate
1 or more of the secondary reasons for discontinuation.  Study disposition information will 
be collected on the Subject Disposition CRF. If “lost to follow-up” is recorded in clinical 
data base, appropriate queries will be sent to investigators in order to collect all the relevant 
reasons for missing data.  (revised per Amendment 03)
Every effort, including proper training of all study participants and their parent/guardian, 
should be made in order to achieve optimal subject retention and prevent missing data, 
especially for the Week 52 primary endpoint.  A retention plan to help avoid missing data 
will be developed and included in study manual. (revised per Amendment 03)
A subject removed from the study for any reason may not be replaced.
9.5.6
Abuse or Diversion of Study Drug
During the study, the investigator will report any concern about abuse or diversion of study 
drugs by completing the Abuse or Diversion of Study Drug CRF.  The DEA Registrant has 
the responsibility to comply with local, state, and Federal laws to notify the Field Division 
Office of the DEA of any theft or significant loss of any controlled substances upon 
discovery of such theft or loss.
9.5.7
Confirmation of Medical Care by Another Physician
The investigator will instruct subjects to inform site personnel when they are planning to 
receive medical care by another physician.  At each visit, the investigator will ask the subject 
whether he or she has received medical care by another physician since the last visit or is 
planning to do so in the future.  When the subject is going to receive medical care by another 
physician, the investigator, with the consent of the subject, will inform the other physician 
that the subject is participating in the clinical study.
9.6
Data Quality Assurance
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines.  Site audits 
will be made periodically by the sponsor’s or the CRO’s qualified compliance auditing team, 
which is an independent function from the study team responsible for conduct of the study.
9.6.1
Data Collection
Data required by the protocol will be collected on the CRFs and entered into a validated data 
management system that is compliant with all regulatory requirements.  As defined by ICH

guidelines, the CRF is a printed, optical, or electronic document designed to record all of the 
protocol-required information to be reported to the sponsor on each study subject.
Data collection on the CRF must follow the instructions described in the CRF Completion 
Guidelines.  The investigator has ultimate responsibility for the collection and reporting of all 
clinical data entered on the CRF.  The investigator or designee as identified on Form 
FDA 1572 must sign the completed CRF to attest to its accuracy, authenticity, and 
completeness.
Completed, original CRFs are the sole property of Eisai and should not be made available in 
any form to third parties without written permission from Eisai, except for authorized 
representatives of Eisai or appropriate regulatory authorities.
9.6.2
Clinical Data Management
All software applications used in the collection of data will be properly validated following 
standard computer system validation that is compliant with all regulatory requirements.  All 
data, both CRF and external data (eg, laboratory data), will be entered into a clinical system.
9.7
Statistical Methods
All statistical analyses will be performed by the sponsor or designee after the study is 
completed and the database is locked and released for unblinding.  Statistical analyses will be 
performed using WinNonlin and SAS software or other validated statistical software as 
required.  Details of the statistical analyses will be included in a separate statistical analysis 
plan (SAP).
9.7.1

Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, while the PP will 
be used as a supportive analysis.  Unless specified otherwise, a 2-sided α=0.05 significance 
level will be used for all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change 
from baseline in BMI will be analyzed using analysis of covariance model (ANCOVA) with 
factors of treatment, sex (male and female) as fixed effect, and the baseline age and BMI as 
covariates.  The missing values will be imputed using a pattern mixture model utilizing 
multiple imputation (MI) assuming the missing values are missing not at random (MNAR).  
The missing values will be imputed at each visit using all available values including the 
retrieved measurement from the postdiscontinuation data.  The details of the analysis model 
and missing value imputation method will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis: The same primary efficacy analyses described above will be repeated based 
on the PP.

Change from baseline in standardized BMI score (Z-score): The same primary efficacy 
analyses described above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed 
and will be described in the SAP.  
Key Secondary Efficacy Analysis
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 
5% BMI reduction at Week 52.  The secondary efficacy endpoint will be analyzed only if the 
test for the primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be 
analyzed using a logistic regression model with factors of treatment, and sex (male and 
female), and baseline BMI as a covariate using FAS.  Subjects with any missing assessment 
at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be 
analyzed using mixed effect model repeated measurement analysis (MMRM) on the FAS for 
study treatment compared to placebo, as appropriate. The model will include all data and will 
include treatment, time, and the interaction of treatment by time as fixed effects, with 
adjustment for sex (male versus female), BMI and age at baseline, and subject as a random 
effect.  (revised per Amendment 03)
Treatment by time interaction will be used to construct the treatment comparisons at a 
specific time.  The MMRM model assumes that the missing data are missing at random and

makes use of all available data even if a subject has missing data at some post-baseline visits.  
An unstructured covariance matrix will be used, and if the model fails to converge, then an 
autoregressive matrix will be used.  (revised per Amendment 03)
Categorical variables will be analyzed using the Cochran Mantel Haenszel test, Chi-square 
test, or logistic regression as appropriate.  Additional analysis may be performed as needed 
using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male 
and female), race (American Indian or Alaska Native, Asian, Black or African American, 
Native Hawaiian or other Pacific Islander, or White), and age. Additional subgroups may be 
explored, if deemed necessary.  (revised per Amendment 03)
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and 
sensitivity analyses.

Pharmacokinetic, Pharmacodynamic, Pharmacogenomic, and Other Biomarker
Analyses
9.7.1.7.1
PHARMACOKINETIC ANALYSES
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling.  The effect of covariates, such as baseline characteristics
or demographics, on PK will be explored.  Derived exposure parameters such as the 
maximum observed concentration and the area under the concentration-time curve from time
0 to 24 hours at steady-state will be calculated from the final PK model using individual 
posterior estimates of the PK parameters and from dosing history.  The PK analysis set will 
be used for this analysis.
9.7.1.7.2
PHARMACODYNAMIC ANALYSES
Change from Baseline in BMI will be assessed as the PD endpoint.  The PD analysis set will 
be used for this analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% 
and ≥10% BMI reduction, and change in waist circumference from baseline) will also be 
assessed as part of the PD analysis.  The PK/PD analysis set will be used for this analysis.
9.7.1.7.3
PHARMACOKINETIC/PHARMACODYNAMIC ANALYSES
Population PK/PD modeling will be used to explore the relationship between lorcaserin 
plasma exposure and response, including but not limited to change in BMI from baseline and 
the probability of achieving at least a 5% and at least a 10% change in BMI from baseline to 
Week 52.  Additionally, exposure-safety relationships for select safety parameters may be 
explored graphically, depending on the data at the end of study.  Any emergent relationship 
may be modeled as appropriate.  Any parameters based on the study data may be considered 
for exploratory assessment for its relationship to PK.

Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments 
including the incidence of AEs (including changes from baseline in physical examination, 
neuromuscular sign assessment for serotonin syndrome, and signs and symptoms of priapism 
and hyperprolactinemia), out-of-normal-range laboratory safety test values, change from 
baseline in laboratory safety test values, ECGs, vital sign measurements, bone mineral 
density and content, total body fat mass and total body lean mass will be summarized by 
treatment group using descriptive statistics or frequency count as appropriate.  (revised per 
Amendments 01 and 03)
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
9.7.1.8.1
EXTENT OF EXPOSURE
Subjects will receive Belviq XR 20 mg or placebo QD for up to 52 weeks. The extent of 
exposure will be characterized by duration of exposure (in weeks) for each treatment group.
Duration of exposure will be defined as the number of weeks between the date the subject 
received the 1st dose of study drug and the date the subject received the last dose of study 
drug.  Duration of exposure will be summarized using descriptive statistics by treatment 
group.  In addition, the duration of exposure will be categorized and will be summarized 
using frequency count by treatment group.
9.7.1.8.2
ADVERSE EVENTS
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities 
(MedDRA).  Adverse events will be coded to the MedDRA (Version 18.0 or higher) lower 
level term closest to the verbatim term.  The linked MedDRA PT and primary system organ 
class (SOC) are also captured in the database.
A treatment-emergent AE (TEAE) is defined as an AE that emerges during treatment (up to 
28 days after the last dose of study drug), having been absent at pretreatment (Baseline) or 
•
Reemerges during treatment (up to 28 days after the last dose of study drug), having been 
present at pretreatment (Baseline) but stopped before treatment, or 
•
Worsens in severity during treatment relative to the pretreatment state, when the AE is 
continuous.
Only those AEs that were treatment emergent will be included in summary tables.  All AEs, 
treatment emergent or otherwise, will be presented in subject data listings.

than 1 TEAE within a specified SOC and PT.
The following summaries will also be presented for the treatment-emergent SAEs.

Incidence of TEAEs leading to death

Incidence of treatment-emergent SAE by SOC and PT

Incidence of treatment-related treatment-emergent SAE by SOC and PT
In addition, subjects with TEAEs leading to discontinuation from study drug and AEs of 
special interest as described in Section 9.5.4.3.2 will be summarized by MedDRA SOC and 
PT for each treatment group. 
9.7.1.8.3
LABORATORY VALUES
Laboratory results will be summarized using Système International units, as appropriate.  For 
all quantitative parameters listed in Section 9.5.1.5.3, the actual value and the change from 
baseline to each postbaseline visit and to the end of treatment (defined as the last 
on-treatment value) will be summarized by visit and treatment group using descriptive 
statistics.  Percentages will be based on the number of subjects with both nonmissing 
baseline and relevant postbaseline results.
Laboratory test results will be assigned a low/normal/high (LNH) classification according to 
whether the value was below (L), within (N), or above (H) the laboratory parameter’s 
reference range.  Within-treatment comparisons for each laboratory parameter will be based 
on 3-by-3 tables (shift tables) that compare the baseline LNH classification to the LNH 
classification at the End of Treatment and the Follow-Up visits.  Similar shift tables will also

presents the criteria that will be used to identify subjects with 
treatment-emergent markedly abnormal laboratory values (TEMAV).  Except for phosphate, 
a TEMAV is defined as a postbaseline value with an increase from baseline to a grade of 2 or 
higher.  For phosphate, a TEMAV was defined as a postbaseline value with an increase from 
baseline to a grade of 3 or higher.  When displaying the incidence of TEMAVs, each subject 
may be counted once in the laboratory parameter high and in the laboratory parameter low 
categories, as applicable.
9.7.1.8.4
VITAL SIGNS
Descriptive statistics for vital signs parameters (eg, systolic and diastolic BP, pulse, 
respiratory rate, temperature, weight) and changes from baseline will be presented by visit
and treatment group.
9.7.1.8.5
ELECTROCARDIOGRAMS
For each ECG parameter (including PR interval, RR interval, QRS interval, QT interval, QTc
interval (Bazett formula), QTc interval (Fridericia formula), and heart rate), the actual value 
and change from baseline will be summarized by visit and treatment group using descriptive 
statistics. 
Shift tables will present changes from baseline in ECG interpretation (categorized as normal; 
abnormal, not clinically significant; and abnormal, clinically significant) to end of treatment. 
Maximum postbaseline QTc (Bazett) and QTc (Fridericia) will also be tabulated by treatment 
group as follows:

Number (percentage) of subjects in greater than 450 msec, greater than 480 msec, and 
greater than 500 msec during the treatment, and

Number (percentage) of subjects with an increment of greater than 30 msec and greater 
than 60 msec from the baseline visit.

group at Week 28 and Week 52. (revised per Amendments 01 and 03)
9.7.2
Determination of Sample Size
The proposed sample size is based on the comparison of the primary efficacy endpoint, 
change from Baseline in BMI at Week 52 between the Belviq XR 20-mg treatment group and 
placebo group.  Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 
260 subjects in a 1:1 ratio (n=130 in the Belviq XR 20-mg treatment group; n=130 in the 
placebo group) will have at least 80% power to detect a treatment difference of 1 kg/m2 in 
BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at 
least a 5% BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, 
this sample of 260 subjects (130 subjects for Belviq XR 20 mg and 130 subjects for placebo) 
will also have greater than 78% power to detect an absolute difference of 20% between the 
Belviq XR 20-mg group and placebo group, using a 2-sided Chi-Square test with α=0.05.  
The assumption used in the sample size calculation is based on the 2 pivotal lorcaserin 
studies, APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

11 PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE 
PROCEDURES)
11.1
Changes to the Protocol
Any change to the protocol requires a written protocol amendment or administrative change 
that must be approved by the sponsor before implementation.  Amendments specifically 
affecting the safety of subjects, the scope of the investigation, or the scientific quality of the 
study require submission to health or regulatory authorities as well as additional approval by 
the applicable IRBs/IECs.  These requirements should in no way prevent any immediate 
action from being taken by the investigator, or by the sponsor, in the interest of preserving 
the safety of all subjects included in the study.  If the investigator determines that an 
immediate change to or deviation from the protocol is necessary for safety reasons to 
eliminate an immediate hazard to the subjects, the sponsor’s medical monitor and the 
IRB/IEC for the site must be notified immediately.  The sponsor must notify the health or 
regulatory authority as required per local regulations.
Protocol amendments that affect only administrative aspects of the study may not require 
submission to health or regulatory authority or the IRB/IEC, but the health or regulatory 
authority and IRB/IEC should be kept informed of such changes as required by local 
regulations.  In these cases, the sponsor may be required to send a letter to the IRB/IEC and 
the Competent Authorities detailing such changes.
11.2
Adherence to the Protocol
The investigator will conduct the study in strict accordance with the protocol (refer to ICH 
E6, Section 4.5).
11.3
Monitoring Procedures
The sponsor’s/CRO’s CRA will maintain contact with the investigator and designated staff 
by telephone, letter, or email between study visits.  Monitoring visits to each site will be 
conducted by the assigned CRA as described in the monitoring plan.  The investigator will 
allow the CRA to inspect the clinical, laboratory, and pharmacy facilities to assure 
compliance with GCP and local regulatory requirements.  The CRFs and subject’s 
corresponding original medical records (source documents) are to be fully available for 
review by the sponsor’s representatives at regular intervals.  These reviews verify adherence 
to study protocol and data accuracy in accordance with local regulations.  All records at the 
site are subject to inspection by the local auditing agency and IRB/IEC review.

the following:
•
Clinic, office, or hospital charts
•
Copies or transcribed health care provider notes which have been certified for accuracy 
after production
•
Recorded data from automated instruments such as IxRS, x-rays, and other imaging 
reports, (eg, sonograms, computerized tomography scans, magnetic resonance images, 
radioactive images, ECGs, rhythm strips, EEGs, polysomnographs, pulmonary function 
tests) regardless of how these images are stored, including microfiche and photographic 
negatives
•
Pain, quality of life, or medical history questionnaires completed by subjects
•
Records of telephone contacts
•
Diaries or evaluation checklists
•
Drug distribution and accountability logs maintained in pharmacies or by research

documentation and urine dip-sticks)
•
Correspondence regarding a study subject’s treatment between physicians or memoranda 
sent to the IRBs/IECs
•
CRF components (eg, questionnaires) that are completed directly by subjects and serve as 
their own source
11.4
Recording of Data
A CRF is required and must be completed for each subject by qualified and authorized 
personnel.  All data on the CRF must reflect the corresponding source document, except 
when a section of the CRF itself is used as source document.  Any correction to entries made 
on the CRF must be documented in a valid audit trail where the correction is dated, the 
individual making the correct is identified, the reason for the change is stated, and the 
original data are not obscured.  Only data required by the protocol for the purposes of the 
study should be collected.
The investigator must sign each CRF.  The investigator will report the CRFs to the sponsor 
and retain a copy of the CRFs.
11.5
Identification of Source Data
All data to be recorded on the CRF must reflect the corresponding source documents.

11.6
Retention of Records
The circumstances of completion or termination of the study notwithstanding, the 
investigator is responsible for retaining all study documents, including but not limited to the 
protocol, copies of CRFs, the Investigator's Brochure, and regulatory agency registration 
documents (eg, Form FDA 1572 ICFs, and IRB/IEC correspondence).  In addition, the 
sponsor will send a list of treatment codes by study subject to the investigator after the 
clinical database for this study has been locked.  The site should plan to retain study 
documents, as directed by the sponsor, for at least 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region or at least 3 years have elapsed since the formal 
discontinuation of clinical development of the investigational product.
It is requested that at the completion of the required retention period, or should the 
investigator retire or relocate, the investigator contact the sponsor, allowing the sponsor the 
option of permanently retaining the study records.
11.7
Auditing Procedures and Inspection
In addition to the routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of ICH GCP and all applicable local 
regulations.  If a government regulatory authority requests an inspection during the study or 
after its completion, the investigator must inform the sponsor immediately.
11.8
Handling of Study Drug
All study drugs will be supplied to the PI (or a designated pharmacist) by the sponsor.  Drug 
supplies must be kept in an appropriate secure area (eg, locked cabinet) and stored according 
to the conditions specified on the drug labels.  Investigational product will be stored in 
accordance with the DEA Regulations for Scheduled III - V Drugs and labeled storage 
conditions.  The investigator (or a designated pharmacist) must maintain an accurate record 
of the shipment and dispensing of the study drug in a drug accountability ledger, a copy of 
which must be given to the sponsor at the end of the study.  An accurate record of the date 
and amount of study drug dispensed to each subject must be available for inspection at any 
time.  The CRA will visit the site and review these documents along with all other study 
conduct documents at appropriate intervals once study drug has been received by the site.
All drug supplies are to be used only for this study and not for any other purpose.  The 
investigator (or site personnel) must not destroy any drug labels or any partly used or unused 
drug supply before approval to do so by the sponsor.  At the conclusion of the study and as 
appropriate during the study, the investigator (or a designated pharmacist) will return all used 
and unused drug containers, drug labels, and a copy of the completed drug disposition form 
to the sponsor’s CRA.

Family-Based Lifestyle Program
Program Overview
All subjects and their caregivers (participating parent or guardian) in Study 403 will be 
encouraged to participate in a standardized weight management program for adolescents 
consisting of multicomponent behavior therapy.  The therapy will focus on healthy eating, 
physical activity, and lifestyle changes that will facilitate weight loss and weight-loss 
maintenance. The role of the caregivers is to support their child or adolescents’ lifestyle 
changes and their taking of study medication.
The objectives of this program are as follows:

Develop a weight management program for all Belviq XR study participants and their 
caregivers (caregivers are instructed in methods to support their adolescents’ progress but 
caregivers are themselves not instructed to lose weight or take medication)

Standardize the weight management program across all study sites

Maximize participant retention

Promote participant’s adherence to both taking study medication and following the 
lifestyle program

cognition from Wide Range 
Assessment of Memory and 
Learning-2 (WRAML-2) to 
Leiter-3
Leiter-3 is selected to replace 
WRAML-2 for the evaluation of the 
change in cognition for the following 
reasons:Lack of availability of 
WRAML-2 in Spanish, Leiter-3’s 
high scientific validity, non-verbal 
format to offer less biased assessment 
for subjects whose second language is 
English, easier and shorter 
administration and short test time 
reducing investigator burden, as well 
as increase probability of the 
subjects’ retention in the study.

Study drug administration will 
be taken at approximately the 
same time each day.  On the 
days of PK sampling and the 
day before the subjects come to 
the clinic for PK sampling, 
study drug will be taken in the 
morning and doses recorded 2 
days prior to the clinic visit.
This will ensure lower variability 
with regard to PK/PD measurements.

strategy
A single dose pharmacokinetic study 
in pediatric obese subjects (APD356-
A001-026) indicated that patients with 
body weight greater than or equal to 
60 kg can be administered a dose 
similar to that given to adults and 
adolescents.  Based on Centers for 
Disease Control and Prevention 
(CDC) growth chart data, almost all 
subjects over 9 years of age are likely 
to be at or over 60 kg body weight.  
Therefore, children age 9 to 11 years 
have been included in the current 
study.

Study Design
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in obese adolescents, 
ages 12 to 17 years.  Approximately 260 subjects will be randomized in a 1:1 ratio to Belviq XR 20 mg QD
(130 subjects) and placebo (130 subjects).  Subjects will be stratified by sex.  Subjects will receive Belviq XR
20 mg or placebo QD in a 1:1 ratio for up to 52 weeks. Throughout the duration of the study, subjects will be 
encouraged to adhere to a lifestyle modification program that includes a standardized, age-appropriate diet and 
exercise counseling. (revised per Amendment 02)
The study will consist of 2 phases: Prerandomization and Randomization.  The Prerandomization Phase will 
last up to 30 days and consist of 1 visit during which subjects will be screened for eligibility.  The 
Randomization Phase consists of a Treatment Period and a Follow-Up Period. The Treatment Period will last 
for a maximum of 52 weeks, with visits at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52.  The Follow-Up Period will 
extend from the End of Treatment visit to the End of Study visit.
Subjects who screen fail can be re-screened only once after 60 days.  All subjects will continue in the study 
until the 52-week evaluation is completed.  Subjects who discontinue treatment prematurely will be followed up 
until study completion.  
Number of Subjects
Approximately500 subjects will be screened to provide260 randomized subjects.  (revised per Amendment 02)

Pharmacokinetic Assessments
Blood samples (approximately 4 mL each) for PK assessment will be collected at Weeks 12, 28, 36, and 52 for 
analysis of Population PK. (revised per Amendment 01)
On the day of the Week 12, 28, and 52 clinic visits, subjects will be instructed not to take their study drug at 
home before the visit,but to bring their study drug to the clinic visit, and take their daily dose at the clinic.  
Two blood samples for determination of plasma concentrations of lorcaserin will be taken: 1 predose (within 
30 minutes before dosing), and 1 within 1 to 3 hours after dosing.  Dose times must be recorded for the last 
2 dosing times before the day of clinic visit. Week 52 PK samples should only be collected if the sample can be 
drawn within 60 hours of the last dose of study drug. (revised per Amendment 01)
On the day of the Week 36 clinic visit, subjects will take their study drug in the morning at home, and will be 
asked to visit the clinic within 4 to 6 hours of dosing that day, during which 1 blood sample for for PK 
assessments will be collected. Dose times must be recorded for the last 2 dosing times prior to the clinic visit.
(revised per Amendment 01)
Pharmacodynamic Assessments

Change from baseline in BMI 

Proportion (%) of subjects achieving at least a 5% and at least a 10% reduction in BMI
Other PD endpoints will be considered based on the data at the end of the study to explore their relationships 
with lorcaserin plasma exposure.
Pharmacogenomic/Pharmacogenetic Assessments
Not applicable
Safety Assessments
Safety assessments will consist of monitoring and recording all adverse events (AEs) and serious adverse events 
(SAEs); electrocardiograms (ECGs); laboratory evaluation for hematology, metabolic function (fasting glucose, 
fasting lipids, and thyroid), adrenal function and biochemical blood and urine bone health assessments; blood 
chemistry and urine values; neuropsychiatric events; periodic measurement of vital signs, neuromuscular signs
for screening potential serotonin syndrome, and signs or symptoms of priapism and hyperprolactinemia; and 
performance of physical examinations. In patients with potential prolactin-related AEs, such as galactorrhea, 
changes in libido, or changes to menstrual cycle, prolactin level will be measured and assessed.
Other Safety Assessments
Effect on growth will be evaluated using the CDC growth chart and bone age determination by x-ray of the 
hand. Sexual maturation will be evaluated by assessing sex hormones and Tanner Staging.   
The C-SSRS will be used to assess all subjects in the study for any signal of depression or suicidal ideation or 
behavior at every visit.  Additionally, screening, diagnosing, monitoring, and measuring the severity of 
depression will be assessed using the PHQ-9 and effects on cognition will be assessed using the Leiter-3.  
(revised per Amendment 01)
Echocardiographic assessments will be used to exclude subjects with FDA-defined valvulopathy, pulmonary 
hypertension, and other major cardiovascular disease (as outlined in Exclusion Criterion No. 3) during the 
Screening Period.  Additionally, cardiac valvular function and pulmonary systolic pressure changes at Weeks
28 and 52 will be assessed. Valvular regurgitation as assessed in the echocardiogram will be rated absent, trace, 
mild, moderate, or severe for the aortic, mitral, and tricuspid valves; the rating will be absent or present for the 
pulmonic valve. The evaluations will be based on guidelines from the American Society of Echocardiography. 
Pulmonary artery pressure will be estimated from the TR jet velocity.

Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, and the PP will be used as a 
supportive analysis.  Unless otherwise specified, a 2-sided α=0.05 significance level will be used in all efficacy 
analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change from baseline in 
BMI will be analyzed using analysis of covariance model (ANCOVA) with factors of treatment,  sex (male and 
female) as fixed effect, and the baseline age and BMI as covariates.  The missing values will be imputed using a 
pattern mixture model utilizing multiple imputation (MI) assuming the missing values are missing not at 
random (MNAR).  The missing values will be imputed at each visit using all available values including the 
retrieved measurement from the postdiscontinuation data.  The details of the analysis model and missing value 
imputation method will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis:  The same primary efficacy analyses described above will be repeated based on the PP.

Change from baseline in standardized BMI score (Z-score):  The same primary efficacy analyses described 
above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed and will be
described in the SAP.
Key Secondary Efficacy Analyses
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 5% BMI reduction at 
Week 52. The secondary efficacy endpoint will be analyzed only if the test for the primary efficacy endpoint is 
statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be analyzed using a logistic 
regression model with factors of treatment, sex (male and female), and baseline BMI as a covariate using FAS.  
Subjects with any missing assessment at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be analyzed using 
mixed effect model repeated measurement analysis (MMRM) and categorical variables will be analyzed using
the Cochran Mantel Haenszel test, Chi-square test, or logistic regression as appropriate.  Additional analysis 
may be performed as needed using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male and female), and 
race (white, black, Asian, and other).  Additional subgroups may be explored, if deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and sensitivity analyses.
Pharmacokinetic Analyses
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using nonlinear mixed 
effects modeling. The effect of covariates such as baseline characteristics or demographics on PK will be 
explored. Derived exposure parameters such as the maximum observed concentration and the area under the 
concentration-time curve from time 0 to 24 hours at steady-state will be calculated from the final PK model 
using individual posterior estimates of the PK parameters and from dosing history. The PK analysis set will be 
used for this analysis.
Pharmacodynamic Analyses
Change from Baseline in BMI will be assessed as the PD endpoint.  The PD analysis set will be used for this 
analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% and ≥10% BMI 
reduction, and change in waist circumference from baseline) will also be assessed as part of the PD analysis.  
The PK/PD analysis set will be used for this analysis.

Pharmacokinetic/Pharmacodynamic Analyses
Population PK/PD modeling will be used to explore the relationship between lorcaserin plasma exposure and 
response, including but not limited to change in BMI from baseline and the probability of achieving at least a 
5% and at least a 10% change in BMI from baseline to Week 52.  Additionally, exposure-safety relationships 
for select safety parameters may be explored graphically depending on the data at the end of study.  Any 
emergent relationship may be modeled as appropriate.  Any parameters based on the study data may be 
considered for exploratory assessment for its relationship to PK.
Pharmacogenomic/Pharmacogenetic Analyses
Not applicable
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments including the incidence 
of AEs (including changes from baseline in physical examination), growth (CDC growth chart and bone age 
determined by x-ray of the hand), sexual maturation (Tanner Staging), out-of-normal-range laboratory safety 
test values, change from baseline in laboratory safety test values, ECGs, and vital sign measurements will be 
summarized by treatment group using descriptive statistics or frequency count as appropriate.  
Other Safety Analyses
In addition, cognition will be evaluated by the Leiter-3, depression will be evaluated by the PHQ-9, and suicidal 
ideation and behavior will be evaluated by the C-SSRS, and will also be summarized by treatment group using 
descriptive statistics or frequency count as appropriate. For echocardiographic assessments, the proportion of 
subjects who develop FDA-defined valvulopathy, the proportion of subjects who develop pulmonary 
hypertension [pulmonary hypertension is defined when the subject’s systolic pulmonary artery pressure 
(SPAP) ≥40 mmHg evaluated by echocardiograph], and change from baseline in SPAP will be summarized by 
treatment group at Week 28 and Week 52 using descriptive statistics or frequency count as appropriate. (revised 
per Amendment 01)
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
Interim Analyses
Not applicable
Sample Size Rationale
The proposed sample size is based on the comparison of the primary efficacy endpoint, change in BMI from 
Baseline to Week 52 between the Belviq XR 20-mg treatment group and placebo group.  Assuming a SD of 
2.2 kg/m2 and a 40% dropout rate, a sample size of 260 subjects in a 1:1 ratio (n=130 in the Belviq XR 20-mg 
treatment group; n=130 in the placebo group) will have at least 80% power to detect a treatment difference of 
1 kg/m2 in BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at least a 5% 
BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, this sample of 260 subjects 
(130 subjects for Belviq XR 20 mg and 130 subjects for placebo) will also have greater than 78% power to 
detect an absolute difference of 20% between the Belviq XR 20-mg group and the placebo group, using a 
2-sided Chi-Square test with α=0.05.
The assumption used in the sample size calculation is based on the 
2 pivotal lorcaserin studies APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

ETHICS
5.1
Institutional Review Boards/Independent Ethics Committees
The protocol, Informed Consent Form (ICF), and appropriate related documents must be 
reviewed and approved by an Institutional Review Board (IRB) or Independent Ethics 
Committee (IEC) constituted and functioning in accordance with International Conference on 
Harmonisation (ICH) Good Clinical Practice (ICH E6), Section 3, and any local regulations 
(eg, Federal Regulations, Title 21 Code of Federal Regulations [21 CFR] Part 56).  Any 
protocol amendment or revision to the ICF will be resubmitted to the IRB/IEC for review and 
approval, except for changes involving only logistical or administrative aspects of the study 
(eg, change in clinical research associate [CRA], change of telephone number[s]).  
Documentation of IRB/IEC compliance with the ICH E6 and any local regulations regarding 
constitution and review conduct will be provided to the sponsor.
A signed letter of study approval from the IRB/IEC chairman must be sent to the principal 
investigator (PI) with a copy to the sponsor before study start and the release of any study 
drug to the site by the sponsor or its designee (ICH E6, Section 4.4).  If the IRB/IEC decides 
to suspend or terminate the study, the investigator will immediately send the notice of study 
suspension or termination by the IRB/IEC to the sponsor.
Study progress is to be reported to IRB/IECs annually (or as required) by the investigator or 
sponsor, depending on local regulatory obligations.  If the investigator is required to report to 
the IRB/IEC, he/she will forward a copy to the sponsor at the time of each periodic report.  
The investigator(s) or the sponsor will submit, depending on local regulations, periodic 
reports and inform the IRB/IEC of any reportable adverse events (AEs) per ICH guidelines 
and local IRB/IEC standards of practice.  Upon completion of the study, the investigator will 
provide the IRB/IEC with a brief report of the outcome of the study, if required.
At the end of the study, the sponsor should notify the IRB/IEC and Competent Authority 
within 90 days.  The end of the study will be the date of the last study visit for the last subject 
in the study.  The sponsor should also provide the IRB/IEC with a summary of the study’s 
outcome.
In the case of early termination or a temporary halt of the study, the investigator should 
notify the IRB/IEC and Competent Authority within 15 calendar days, and a detailed written 
explanation of the reasons for the termination/halt should be given.

studies, including Part 50 and Part 56 concerning informed subject consent and IRB 
regulations and applicable sections of US 21 CFR Part 312
5.3
Subject Information and Informed Consent
As part of administering the informed consent document, the investigator must explain to 
each subject and guardian/legally authorized representative the nature of the study, its 
purpose, the procedures involved, the expected duration, the potential risks and benefits 
involved, any potential discomfort, potential alternative procedure(s) or course(s) of 
treatment available to the subject, and the extent of maintaining confidentiality of the 
subject’s records.  Each subject must be informed that participation in the study is voluntary, 
that he/she may withdraw from the study at any time, and that withdrawal of consent will not 
affect his/her subsequent medical treatment or relationship with the treating physician.
This informed consent should be given by means of a standard written statement, written in 
nontechnical language.  The subject or the subject’s legally acceptable representative should 
understand the statement before signing and dating it and will be given a copy of the signed 
document.  If a subject is unable to read or if a legally acceptable representative is unable to 
read, an impartial witness should be present during the entire informed consent discussion.  
After the ICF and any other written information to be provided to subjects is read and 
explained to the subject or the subject’s legally acceptable representative, and after the 
subject or the subject’s legally acceptable representative has orally consented to the subject’s 
participation in the study and, if capable of doing so, has signed and personally dated the 
ICF, the witness should sign and personally date the consent form.  The subject will be asked 
to sign an ICF before any study-specific procedures are performed.  No subject can enter the 
study before his/her informed consent has been obtained.  The adolescent participant will 
provide written assent and the caregiver/guardian will provide written informed consent.
An unsigned copy of an IRB/IEC-approved ICF must be prepared in accordance with 
ICH E6, Section 4, and all applicable local regulations (Federal Regulations, 
Title 21 CFR Part 50, for studies in the United States).  Each subject must sign an approved 
ICF before study participation.  The form must be signed and dated by the appropriate 
parties.  The original, signed ICF for each subject will be verified by the sponsor and kept on 
file according to local procedures at the site.

INTRODUCTION
7.1
Indication
Obesity has become a global epidemic, causing a serious public health concern.  In the 
United States, the prevalence of obesity in adolescents ages 12 and 19 years has almost 
doubled over the past 2 decades.  The rate increased from 10.5% between 1988 and 1994 to 
20.5% between 2011 and 2012 (CDC/NCHS, 2013).  Obesity in adolescents, defined in the 
United States as greater than or equal to the 95th percentile in gender- and age-specific body 
mass index (BMI), continues to grow at an alarming rate in the United States and globally.  
Based on data (Wang and Lobstein, 2006) using various criteria for the definition of obesity 
that included more than 30 countries in Europe, North America, Asia, and the West Pacific, 
prevalence of obesity in these countries has also increased significantly, at a rate comparable 
to that in the United States.
Adolescent obesity has many negative implications for both the health and well-being of the 
individual as well as for society.  These include increased susceptibility to a host of diseases, 
chronic health disorders, psychological disorders, and premature death (Flegal, et al., 2005; 
Rofey, et al., 2009).  Increases in the prevalence of overweight and obese adolescents may
result in a decrease in life expectancy for the 1st time in 200 years (Peeters, et al., 2003).
As a result, there is a significant impact on the cost of healthcare.  It is estimated that medical 
costs due to overweight adolescents are approximately $14 billion per year in the United 
States (Trasande and Chatterjee, 2009).  Obesity-related medical costs in general are
expected to rise significantly because today’s obese adolescents are likely to become 
tomorrow’s obese adults (Whitaker, et al., 1997).
Current approaches to weight management in adults include lifestyle modification, 
pharmacotherapy, and invasive bariatric procedures.  Lifestyle modification involves a 
combination of diet, exercise, and behavioral change, and is the preferred and essential 
strategy for weight management in obese and overweight individuals, including adolescents.  
Although lifestyle modification can be very efficacious in some patients, adherence to the 
prescribed regimens is often poor.  As such, lifestyle modification alone is often not adequate 
and the weight loss is often transient.  On the other hand, bariatric surgery and various other 
invasive procedures are generally reserved for the severely obese population. 
Pharmacotherapy can play a significant role in weight management programs, and is often 
combined with lifestyle modification to enhance weight loss beyond that which is normally 
achieved with diet and exercise alone.  Current pharmacotherapies offer the potential to 
significantly augment weight loss when combined with diet and exercise, but are rarely used 
for adolescents.
The current standard of care for treatment of obesity in adolescent subjects ranges from
behavioral therapy including lifestyle intervention to the rare use of pharmacotherapy in 
adolescents over 12 years of age (McGovern, et al, 2008; Spear, et al, 2007).  Xenical®
(orlistat) is currently the only product available for weight control in obese adolescent 
patients 12 to 16 years of age.  However, it is associated with gastrointestinal side effects

(Xenical PI. 2015), and the treatment effect of Xenical is modest. In a study that included 
539 obese adolescents with BMI above the 97th percentile, Xenical demonstrated a 0.86 BMI 
reduction relative to placebo after 52 weeks of treatment (-0.55 BMI in the Xenical treatment 
group versus +0.31 BMI in the placebo group) (FDA, 2003; Chanoine, et al, 2005).
Obtaining maximum retention in the study is a major goal in order to minimize missing data.  
A number of strategies have been used in prior adolescent weight loss studies that will be 
used in the present study to help retain participants.  These include a highly trained and 
competent staff, ample waiting area, readily available parking (at no cost), access to mass 
transit, and reminder and follow-up calls.  In addition, we will provide fun and interactive 
group sessions with games and hands-on nutrition and physical activity demonstrations, 
random raffle drawings, social events, birthday and holiday cards, and newsletters.  
Furthermore, we will make home visits for assessments of families, as needed, to maximize 
data collection. 
By using these retention strategies, we hope that we will maximize 
participant retention, which will help us cope with missing data.

APD356/Belviq (lorcaserin hydrochloride)
7.1.1.1
Mechanism of Action
Belviq is a selective serotonin 2c receptor agonist which was approved by the US Food and 
Drug Administration (FDA) on 27 Jun 2012 as an adjunct to a reduced-calorie diet and 
increased physical activity for chronic weight management in adult patients with a BMI of at 
least 30 kg/m2 (obese), or adult patients with a BMI greater than or equal to 27 kg/m2
(overweight) in the presence of at least 1 weight-related comorbid condition.
7.1.1.2
Clinical Experience with APD356/Belviq (lorcaserin hydrochloride)
The Phase 3 clinical evaluation of Belviq in studies of more than 7700 adult subjects, 
including 604 subjects with Type 2 diabetes mellitus, demonstrated clinically meaningful 
efficacy and a safety profile that includes minimal and easily managed risks.  In each of the 
individual studies and in the pooled efficacy analyses, the Belviq dose met the following 
prespecified endpoints:

A significantly greater proportion of adult subjects taking Belviq 10 mg twice per day 
(BID) (47%) lost at least 5% of baseline body weight at 52 weeks as compared to 
subjects taking placebo (23%).  A significantly greater proportion of subjects taking 
Belviq 10 mg BID (22.4%) lost at least 10% of baseline body weight at 1 year as 
compared to subjects taking placebo (8.7%). 

The mean weight loss at 1 year in adult subjects taking Belviq 10 mg BID (-5.8 kg) was 
significantly greater than that in subjects taking placebo (-2.5 kg).
An integrated evaluation of the data from the pediatric, adolescent, and adult subjects 
revealed that the relationship between lorcaserin area under the curve (AUC) and body 
weight in pediatric and adult subjects is consistent irrespective of the individual studies or 
age range of the study population. Irrespective of age, lorcaserin AUC values in the pediatric 
subjects with body weight of greater than 60 kg overlapped with the data observed from the 
studies involving adult subjects, suggesting a fixed dose approach similar to adults can be

used for adolescent subjects with body weight greater than 60 kg.
In adolescent obese populations, it is anticipated that Belviq XR will result in similar effects.
As part of FDA postmarketing requirements, this study is designed to characterize the 
efficacy and safety of Belviq XR in adolescent obese populations in the United States.  It is 
also intended to support an indication for chronic weight management for obese adolescents 
ages 12 to 17 years old. 
7.1.2
Study Rationale
There is no specific FDA guidance for the approval of a weight loss product for adolescents.  
In adults, the Division’s 2007 draft Guidance for Industry Developing Products for Weight 
Management indicate that the product needs to satisfy either of the following mean or 
categorical criteria after 1 year of treatment:

The difference in mean weight loss between the active-product and placebo-treated 
groups is at least 5% and the difference is statistically significant.

The proportion of subjects who lose at least 5% of baseline body weight in the 
active-product group is at least 35%, is approximately double the proportion of subjects 
in the placebo-treated group who lose at least 5% of baseline body weight, and the 
difference between groups is statistically significant.
FDA awarded a weight management indication for Belviq based on Phase 3 study results 
which achieved the categorical criteria. In a Phase 3 study, a significantly greater proportion 
of subjects taking Belviq (47%) lost at least 5% of baseline body weight at 1 year as 
compared to subjects taking a placebo (23%).  It is anticipated that a similar effect will be 
demonstrated in obese adolescents, where weight loss will be assessed using BMI
measurements to account for growth. In this study, the objective is to demonstrate that BMI
reduction will be achieved during 52 weeks of treatment with Belviq XR 20 mg administered 
once daily (QD) compared to placebo in obese adolescents.
In the Phase 3 orlistat study in obese adolescents mentioned above, the proportion of subjects 
who lost at least 5% body weight is relatively low. At the end of the study at Week 52, only 
26.5% of the subjects achieved a 5% or greater BMI reduction compared to 15.7% in the 
placebo group. The placebo-corrected BMI reduction was about 0.86 kg/m2.  
There are limited trials for weight reduction in the adolescent population, ages 12 to 17 years
(Peirson, et al, 2015).  Thirty-one studies (29 behavioral, 2 pharmacological and behavioral) 
were included in a meta-analysis of randomized studies conducted in primary care centers in 
overweight and obese children and youth ages 2 to 18 years using behavioral (diet, exercise,
and lifestyle) and pharmacological interventions and providing 6-month postbaseline BMI or 
prevalence of overweight or obesity. Both interventions showed a significant effect on BMI 
in favor of treatment (behavioral: 
standardized mean difference [SMD] -0.54, 
95% confidence interval [CI]
-0.73, -0.36; orlistat plus behavioral: 
SMD -0.43, 
95% CI -0.60, -0.25). The studies reported no significant difference between groups in the 
likelihood of reduced prevalence of overweight or overweight and obese. A great deal of 
variation was noted across efficacious interventions.
In conclusion, this meta-analysis

demonstrated low-quality evidence that behavioral treatments alone are associated with a 
smaller effect in terms of reduced BMI compared with the effect shown by combined 
behavioral and pharmacological interventions. This may be because the effect size in the 
randomized, double blind, placebo controlled, phase 3 orlistat study in adolescents was 
relatively low and there was a lack of maintenance effect. These subjects started to regain 
their BMI after 6 months of treatment. At end of the study, only 26.5% of subjects achieved 
a 5% or greater BMI reduction compared to 15.7% in placebo group. In a sibutramine 
Phase 3 study in obese adolescents, a substantially higher proportion of subjects (69%) 
treated with sibutramine achieved at least a 5% BMI reduction compared to 21% of subjects 
in the placebo group. In addition, sibutramine resulted in a substantial reduction in mean 
BMI (between-group difference, 2.9 kg/m2) and mean weight (between-group difference, 
8.4 kg) compared to placebo (Berkowitz, et al, 2006).  Unlike the weight loss effect of Belviq
in adults and sibutramine in adolescents, subjects in the orlistat study started to increase their 
BMI after 6 months of treatment.
In this study, it is assumed that treatment with Belviq XR 20 mg will lead to a BMI reduction
of more than 1 kg/m2, and a higher proportion of subjects will achieve more than a 5% and 
10% BMI reduction compared to placebo.  A between-group difference of 24% is the basis 
for the conservative assumption of a 20% effect size in the current study.
In addition, the total sample size of260 subjects will be adequate to assess safety and 
exposure based on previous adolescent studies with weight management products (orlistat 
sibutramine, and liraglutide 3 mg) (FDA, 2003; Chanoine, et al., 2005; Berkowitz, et al,
2006; CT.gov NCT02918279) and other metabolic or dyslipidemia medication products
(ezetimibe, simvastatin) (FDA, 2007).  (revised per Amendment 02)

INVESTIGATIONAL PLAN
9.1
Overall Study Design and Plan
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in 
obese adolescents ages 12 to 17 years.  Approximately 260 subjects will be randomized in a 
1:1 ratio to Belviq XR 20 mg QD (130 subjects) and placebo (130 subjects).  Subjects will be 
stratified by sex.  Subjects will receive Belviq XR 20 mg or placebo QD in a 1:1 ratio for up 
to 52 weeks. Throughout the duration of the study, subjects will be encouraged to adhere to 
a lifestyle modification program that includes a standardized, age-appropriate diet and 
exercise counseling (see Appendix 2).  (revised per Amendment 02)
The study will consist of 2 phases:
Prerandomization and Randomization.  The 
Prerandomization Phase will last up to 30 days and consists of 1 visit during which subjects 
will be screened for eligibility.  The Randomization Phase consists of a Treatment Period and 
a Follow-Up Period.  The Treatment Period will last for a maximum of 52 weeks, with visits 
at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52; the Follow-Up Period will extend from the 
End of Treatment (EOT) visit to the End of Study (EOS) visit.
Subjects who screen fail can be rescreened only once after 60 days.  All subjects will 
continue in the study until the 52-week evaluation is completed.  Subjects who discontinue 
treatment prematurely will be followed up until study completion.
9.1.1
Prerandomization Phase
Screening will occur during the Prerandomization Phase at Visit 1.
9.1.1.1
Screening Period
The purpose of the Screening Period is to obtain the informed consent and assent and to 
establish protocol eligibility.  Procedures to be followed when obtaining informed consent 
are detailed in Section 5.3.  Careful initial screening is important in the recruitment of 
families who both fully understand the requirements of this 1 year, randomized, controlled 
trial and are truly interested in participation.  Interested caregivers and adolescents will be 
screened by phone to assess preliminary entry criteria.  Candidates will be given a brief 
description of the program and general study requirements, with an adolescent and a 
caregiver who is willing to participate.  If preliminary entry criteria are met, adolescents and 
their caregivers will be invited to an initial in-clinic meeting to further discuss the study.  A 
complete description of the study including assessments, the number of visits, the lifestyle 
program, the fact that the adolescent would be taking either the study drug or a placebo, the
duration of the study, and the necessity of having an adolescent wishing to participate as well 
as a participating caregiver will be described.  Consent and assent will be obtained and copies 
of the signed forms will be provided to families.  The importance of the study and its 
scientific merit will be discussed.  Ineligible adolescents will be referred to local weight 
management resources.  Screening period assessments and timing thereof are shown in 
Section 9.5.2.

Discussion of Study Design, Including Choice of Control Groups
The proposed dose and dosing frequency of Belviq XR in this study is 20 mg QD.  The PK 
parameters of a single 10-mg dose of Belviq were evaluated in healthy, adolescent obese 
subjects in Study APD356-025.  Overall, the PK parameters of Belviq and its main 
metabolites, M1 and M5, were similar to those in adults.  Following a single, oral 
administration of Belviq 10 mg to a total of 8 healthy adolescent (ages 12 to 17 years old) 
obese subjects, the mean maximum concentration observed and the area under the 
concentration-time curve from time zero to infinity (AUC(0-inf)) were 36.5 ng/mL and 
464 hr×ng/mL, respectively.  The mean Belviq terminal phase half-life was 9.70 hours, 
similar to that observed in adults, thus supporting a similar dosing frequency (QD) in 
adolescent subjects.
Additionally, a single dose PK study in 8 healthy obese pediatric subjects ages 6 to 11 years 
of age was performed. The PK analysis after a single 10-mg dose of lorcaserin revealed that 
the lorcaserin AUC(0-inf) values tended to increase with decreasing body weight and age.
However, the body weight normalized AUC(0-inf) values were similar across the age groups, 
therefore the data indicated no effect of age on the lorcaserin PK. Integrated assessment of 
the PK versus body weight relationship, pooling the data from pediatric and adult subjects 
from previous studies, suggested that the lorcaserin area under the curve values for subjects 
with body weight of at least 60 kg overlapped with the area under the curve values from 
adolescents and adults. Therefore, no dose adjustment relative to adults and adolescents is 
deemed necessary for pediatric or adolescent subjects with a body weight of at least 60 kg.
Based on CDC growth charts, the likelihood of subjects who are older than 12 years of age 
having a body weight of less than 60 kg is very low; therefore, the current study as designed 
to enroll subjects between 12 to 17 years of age with body weight at least 60 kg, will cover
majority of the population of interest.  The targeted study population comprises 260 obese 
adolescents 12 to 17 years of age, with a body weight at least 60 kg.  (revised per 
Amendment 02)
Obese adolescents will be identified using gender- and age-specific BMI measurement.  
Obesity in adolescents is defined by US Expert committee recommendations as BMI in or 
above the 95th percentile (Barlow, 2007).

Randomization will be used in this study to avoid bias in the assignment of subjects to 
treatment, to increase the likelihood that known and unknown subject attributes 
(eg, demographics, baseline characteristics) are balanced across treatment groups, and to 
ensure the validity of statistical comparisons across treatment groups.  Blinding to treatment 
will be used to reduce potential bias during data collection and evaluation of endpoints.

Selection of Study Population
Approximately 500 subjects will be screened to ensure that 260 subjects will be randomized.  
(revised per Amendment 02)
Subjects who do not meet all inclusion criteria or do meet any exclusion criteria will not be

TR jet, the pulmonary flow acceleration time measured at the right ventricular 
outflow tract (RVOTAT), will be used to assess eligibility. Patients with a 
RVOTAT ≤100 msec will be excluded, suggesting an elevated mean SPAP;

All packaging and labeling will be performed according to Good Manufacturing Practices 
and GCP guidelines.
Study drug must be stored as instructed on the study drug label and in accordance with the
DEA Regulations for Schedule IV Controlled Drugs (US sites). Study drug must be kept
in a secure location as required by DEA regulations and carefully stored at the study site
within its original container.
The investigator (or pharmacist, as appropriate) must maintain records of the delivery of
the study drug to the study site, the inventory at the site, use for each subject, and return of
the study drug to a delegate of the sponsor. Total study site accountability will be conducted
at the end of the study and the investigator must explain any discrepancies.
A Drug Dispensing Log must be kept current and should contain at least the following 
information:

Identification (subject ID number and initials) of the subject to whom the study drug was 
dispensed
•
The dates and unique kit or carton identifiers for dispensed study drug
•
Initial inventory on receipt of drug at the site
•
Final inventory on completion of the study
All records and inventory must be available for inspection by the clinical study
monitor.
9.4.2.4
Storage Conditions
Where applicable, investigational product will be stored in accordance with the DEA 
Regulations for Scheduled III to V Drugs and labeled storage conditions.  Temperature 
monitoring is required at the storage location to ensure that the study drug is maintained 
within an established temperature range.  The investigator or designee is responsible for 
ensuring that the temperature is monitored throughout the total duration of the study and that 
records are maintained; the temperature should be monitored continuously by using either an 
in-house validated data acquisition system, a mechanical recording device, such as a 
calibrated chart recorder, or by manual means, such that minimum and maximum 
thermometric values over a specific time period can be recorded and retrieved as required.

Method of Assigning Subjects to Treatment Groups
Subjects will be assigned to treatments based on a computer-generated randomization 
scheme that will be reviewed and approved by an independent statistician.  The 
randomization scheme and identification for each subject will be included in the final clinical 
study report for this study.
Subjects will be centrally stratified by sex (male and female).  Within each stratum, subjects 
will be randomized to receive either Belviq XR 20 mg or placebo QD in a 1:1 ratio.  
Randomization will be performed centrally by an interactive voice or web response system 
(IxRS).  The IxRS or clinical supply vendor will generate the randomized identification
numbers to be included on study packaging.  Upon signature of the ICF, the investigator or 
designee will access the IxRS to register the subject information.  At Randomization, the 
IxRS will assign each subject a unique randomization number.  At each subsequent visit 
during the Treatment Period and Follow-Up Period, the investigator or designee will access 
IxRS to obtain dispensing information and to register the subject’s visit.
9.4.4
Selection and Timing of Dose for Each Subject
Subjects should take the study medication once daily at approximately the same time of 
every day, and be encouraged to take the study medication with an adequate amount of water 
(8 oz. or 240 mL).
9.4.5
Blinding
During the Randomization Phase, subjects and all personnel involved with the conduct and 
interpretation of the study, including investigators, site personnel, and sponsor staff will be 
blinded to the treatment codes.  Randomization data will be kept strictly confidential, filed 
securely by an appropriate group with the sponsor or CRO, and accessible only to authorized 
persons (eg, Eisai Global Safety) until the time of unblinding, per the SOP.
A master list of all treatments and the subject numbers associated with them will be 
maintained in a sealed envelope by the clinical supply vendor, the IxRS vendor, and the 
sponsor.  In the event that emergency conditions require knowledge of the study treatment 
given, the blind may be broken via the code breaker facility within the IxRS.  Emergency 
procedures for revealing drug codes are given in Section 9.5.4.5.  If possible, before breaking 
the blind, the investigator should consult with the sponsor or designee to ascertain the 
necessity of breaking the code.
9.4.6
Prior and Concomitant Therapy
Any medication (including OTC medications) or therapy administered to the subject during 
the study (starting at the date of informed consent) will be recorded on the Prior and
Concomitant Medication Case Report Form (CRF) or Non-Pharmacological Procedures 
CRF.  The investigator will record on the Adverse Event CRF any AE for which the 
concomitant medication/therapy was administered. If the concomitant medication/therapy is

changes to menstrual cycle, prolactin level will be measured and assessed.  
9.5.1.5.1
ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered an investigational product.  An AE does not necessarily have a causal 
relationship with the medicinal product.  For this study, the study drug is Belviq XR
(lorcaserin hydrochloride).
The criteria for identifying AEs in this study are:
•
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or

Page 41 of 78
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE)
•
Any new disease or exacerbation of an existing disease 
•
Any deterioration in non-protocol-required measurements of a laboratory value or other 
clinical test (eg, ECG, x-ray) that results in symptoms, a change in treatment, or 
discontinuation of study drug
•
Recurrence of an intermittent medical condition (eg, headache) not present pretreatment 
(Baseline)
•
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of study drug, or withholding 
of study drug, whether prescribed in the protocol or not.
All AEs observed during the study will be reported on the Adverse Event CRF.  All AEs, 
regardless of relationship to study drug or procedure, should be collected beginning from the 
time the subject signs the study ICF through the last visit in the Treatment Phase.  Subjects 
who fail screening primarily due to AE(s) must have the AE(s) leading to screen failure 
reported on the Screening Disposition CRF.  SAEs will be collected for 28 days after the last 
dose.
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute 
an AE.  Medical and scientific judgment should be exercised in deciding whether an isolated 
laboratory abnormality should be classified as an AE.  Any laboratory abnormality 
considered to constitute an AE should be reported on the Adverse Event CRF. 
Abnormal ECG (corrected QT interval [QTc]) results, if not otherwise considered part of a 
clinical symptom that is being reported as an AE, should be considered an AE if the QTc 
interval is greater than 450 msec and there is an increase of more than 60 msec from baseline.  
Any ECG abnormality that the investigator considers as an AE should be reported as such.
It is the responsibility of the investigator to review the results of the Leiter-3, C-SSRS, and 
PHQ-9 for all subjects and determine if any result constitutes an AE.  Medical and scientific 
judgment should be exercised in deciding whether an isolated suicidality rating scale 
response should be classified as an AE (see Section 9.5.1.5.10 for a description of the 
C-SSRS).  (revised per Amendment 01)
All AEs must be followed for 28 days after the subject’s last dose or until resolution, 
whichever comes first.  All SAEs must be followed to resolution or, if resolution is unlikely, 
to stabilization.
Every effort must be made by the investigator to categorize each AE according to its 
severity and its relationship to the study treatment.

Assessing Severity of Adverse Events
Adverse events will be graded on a 3-point scale (mild, moderate, severe) and reported in the 
detail indicated on the CRF.  The definitions are as follows:
Mild
Discomfort noticed, but no disruption of normal daily activity
Moderate Discomfort sufficient to reduce or affect normal daily activity
Severe
Incapacitating, with inability to work or to perform normal daily activity
The criteria for assessing severity are different than those used for seriousness (see
Section 9.5.1.5.2 for the definition of an SAE).
Assessing Relationship to Study Treatment
Items to be considered when assessing the relationship of an AE to the study treatment are:
•
Temporal relationship of the onset of the event to the initiation of the study treatment
•
The course of the event, especially the effect of discontinuation of study treatment or 
reintroduction of study treatment, as applicable
•
Whether the event is known to be associated with the study treatment or with other 
similar treatments
•
The presence of risk factors in the study subject known to increase the occurrence of the 
event
•
The presence of nonstudy, treatment-related factors that are known to be associated with 
the occurrence of the event
Classification of Causality
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question:
Is there a reasonable possibility that the study drug caused the AE?
Yes (related)
A causal relationship between the study drug and the AE is a reasonable 
possibility.
No (not related) A causal relationship between the study drug and the AE is not a 
reasonable possibility.
9.5.1.5.2
SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An SAE is any untoward medical occurrence that at any dose:
•
Results in death

•
Is life-threatening (ie, the subject was at immediate risk of death from the AE as it 
occurred; this does not include an event that, had it occurred in a more severe form or 
was allowed to continue, might have caused death)
•
Requires inpatient hospitalization or prolongation of existing hospitalization
•
Results in persistent or significant disability/incapacity
•
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug)
Other important medical events that may not be immediately life-threatening or result in 
death or hospitalization but, when based on appropriate medical judgment, may jeopardize 
the subject or may require intervention to prevent one of the outcomes in the definition of 
SAE listed above should also be considered SAEs.  Medical and scientific judgment should 
be exercised in deciding whether expedited reporting is appropriate in such situations. 
For this study, the following events should always be considered serious and reported as an 
important medical event if it does not meet other serious criteria:
•
Serotonin syndrome (must have at least 1 of the following: 
Spontaneous clonus; 
Inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus)
•
Psychosis
•
Suicidal behavior
•
Priapism
•
New onset valvular heart disease
•
New onset pulmonary hypertension
•
Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas of 
the skin
•
Fibroadenomas of the breast or ductal carcinoma in situ
The following additional study specific AE of interest should be reported using the 
procedures detailed in Reporting of SAEs (Section 9.5.4.1), even if the study specific event 
does not meet serious criteria.  If the event meets seriousness criteria, it should be reported as 
an SAE as above.  However, if the event listed below does not meet serious criteria, it should 
be noted as nonserious on the Adverse Event CRF:  
•
Suicidal ideation   
•
Euphoria 
In addition to the above, events associated with special situations include pregnancy or 
exposure to study drug through breastfeeding; AEs associated with study drug overdose,

misuse, abuse, or medication error.  These events associated with special situations are to be 
captured using the SAE procedures but are to be considered as SAEs only if they meet 1 of 
the above criteria.  All AEs associated with special situations are to be reported on the CRF 
whether or not they meet the criteria for SAEs.  
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization.
The following hospitalizations are not considered to be SAEs because there is no “AE” (ie, 
there is no untoward medical occurrence) associated with the hospitalization:
•
Hospitalizations for respite care
•
Planned hospitalizations required by the protocol  
•
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed after study drug administration)
•
Hospitalization for administration of study drug or insertion of access for administration 
of study drug
•
Hospitalization for routine maintenance of a device (eg, battery replacement) that was in 
place before study entry

method.  BP and pulse will be measured after the subject has been sitting for 5 minutes.  All 
BP measurements should be performed on the same arm, preferably by the same person. 
When vital signs are to be obtained concurrently with PK or other blood samples, the vital 
sign measurements will be performed before drawing blood samples in order to maximize the 
accuracy of blood sampling times while minimizing the potential effects of blood drawing on 
recordings obtained during safety assessments.

An ECG abnormality may meet the criteria of an AE as described in this protocol (see
Section 9.5.1.5.1) and the CRF Completion Guidelines.  In these instances, the AE 
corresponding to the ECG abnormality will be recorded on the Adverse Events CRF.
For ECG abnormalities meeting criteria of an SAE (see Section 9.5.1.5.2), the site must fax 
or email the SAE report including the ECG report to the sponsor using the SAE form (see 
Section 9.5.4.1).
9.5.1.5.10 OTHER SAFETY ASSESSMENTS
Leiter-3
The Leiter International Performance Scale–Third Edition (Leiter-3) is widely used 
non verbal measure of intelligence, memory, and attention in those between the ages of 3 and 
75 years. 
The Attention/Memory Battery consists of 5 subtests: 2 measure nonverbal 
attention; 2 measure memory; and 1 measures cognitive interference (nonverbal Stroop test). 
These subtests are combined to produce a Memory and Processing Speed composite scores, 
normalized to a mean of 100 and standard deviation of 15. The Leiter-3 will be used to 
assess lorcaserin effects on cognition, specifically, attention and memory. In addition, signs 
and symptoms of cognition-related AEs, including impairments in attention, memory, and 
adverse effects on schoolwork will be captured in the eCRF. (revised per Amendment 01)
PHQ-9
The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and 
measuring the severity of depression:

The PHQ-9 incorporates Diagnostic and Statistical Manual of Mental Disorders, 4th 
Edition (DSM-IV) depression diagnostic criteria with other leading major depressive 
symptoms into a brief self-report tool.

The tool rates the frequency of the symptoms which factors into the scoring severity 
index.

Question 9 on the PHQ-9 screens for the presence and duration of suicide ideation.

A follow-up, non-scored question on the PHQ-9 assigns weight to the degree to which 
depressive problems have affected the patient's level of function. 
C-SSRS
The C-SSRS collects information pertinent to suicidal ideation and actions.  It consists of a 
Baseline version which will be administered at baseline and a Since Last Visit version which 
will be administered at the remaining visits.  C-SSRS will be used to assess signal of 
depression and suicidal ideation or behavior. Qualified personnel must evaluate positive 
responses on the C-SSRS and take appropriate action as detailed in the training and 
certification process for administering the C-SSRS.  It will be performed at Screening and at 
study visits as designated in the Schedule of Procedures/Assessments (Table 2). (revised per 
Amendment 01)

Tanner Staging
The pubic hair growth (both sexes), genital (males only) and breast (females only) 
development of subjects will be using Tanner Staging (Marshall, 1970). Subjects will be 
examined by the investigator as designated in the Schedules/Assessments (Table 2). (revised 
per Amendment 01)
Echocardiogram
Echocardiograms will be obtained on the Schedule of Procedures/Assessments (Table 2). 
Valvular regurgitation in echocardiogram will be rated absent, trace, mild, moderate, or 
severe for the aortic, mitral, and tricuspid valves; the rating will be absent or present for the 
pulmonic valve.  The evaluations will be based on guidelines from the American Society of 
Echocardiography. Pulmonary artery pressure will be estimated from the TR regurgitant jet 
velocity.

Reporting of Serious Adverse Events, Pregnancy, and Events Associated 
with Special Situations
9.5.4.1
Reporting of Serious Adverse Events
All SAEs, regardless of their relationship to study treatment, must be reported on a 
completed SAE form by email or fax as soon as possible but no later than 1 business 
day from the date the investigator becomes aware of the event.
SAEs, regardless of causality assessment, must be collected through the through the last visit
and for 28 days after the subject’s last dose.  All SAEs must be followed to resolution or, if 
resolution is unlikely, to stabilization.  Any SAE judged by the investigator to be related to 
the study treatment or any protocol-required procedure should be reported to the sponsor 
regardless of the length of time that has passed since study completion.
The detailed contact information for reporting of SAEs is provided in the Investigator Study 
File.
For urgent safety issues, please ensure all appropriate medical care is administered to the 
subject and contact the appropriate study team member listed in the Investigator Study File.
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report.  This includes the investigator’s assessment of causality.
Any follow-up information received on SAEs should be forwarded within 1 business day of 
its receipt.  If the follow-up information changes the investigator’s assessment of causality, 
this should also be noted on the follow-up SAE form.
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested by 
the sponsor.
The investigator must notify his/her IRB/IEC of the occurrence of the SAE, in writing, if 
required by their institution.  A copy of this communication must be forwarded to the sponsor 
to be filed in the sponsor’s Trial Master File.
9.5.4.2
Reporting of Pregnancy and Exposure to Study Drug through Breastfeeding
Any pregnancy in which the estimated date of conception is either before the last visit or 
within 28 days of last study treatment or any exposure to study drug through breastfeeding 
during study treatment or within 28 days of last study treatment must be reported.
If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, this 
should be reported regardless of the length of time that has passed since the exposure to study 
treatment.

A congenital anomaly, death during perinatal period, an induced abortion, or a spontaneous 
abortion are considered to be an SAE and should be reported in the same time frame and in 
the same format as all other SAEs (see Section 9.5.4.1).
Pregnancies or exposure to study drug through breastfeeding must be reported by fax or 
email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy.  The contact information for the reporting of pregnancies 
and exposure to study drug through breastfeeding is provided in the Investigator Study File.  
The Pregnancy Report Form must be used for reporting.  All pregnancies must be followed to 
outcome.  The outcome of the pregnancy must be reported as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the outcome.
A subject who becomes pregnant must be withdrawn from the study. 
9.5.4.3
Reporting of Events Association with Special Situations
9.5.4.3.1
REPORTING OF ADVERSE EVENTS ASSOCIATED WITH STUDY DRUG OVERDOSE,
MISUSE, ABUSE, OR MEDICATION ERROR
Adverse events associated with study drug overdose, misuse, abuse, and medication error 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication error are defined as follows:
Overdose
Accidental or intentional use of the study drug in an amount higher
than the protocol-defined dose
Misuse
Intentional and inappropriate use of study drug not in accordance with 
the protocol or authorized dose, route of administration, or 
indication(s) or use of prescription-only study drug without a 
prescription
Abuse
Sporadic or persistent intentional excessive use of study drug 
accompanied by harmful physical or psychological effects
Medication error
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of the 
healthcare professional, subject, or consumer.  Such events may be 
related to professional practice, healthcare products, occupational 
exposure, procedures, or
systems,
including prescribing,
order 
communication,
product
labeling, 
packaging, 
nomenclature,
compounding,
dispensing,
distribution,
administration, education,
monitoring, or use.
All AEs associated with overdose, misuse, abuse, or medication error should be captured on 
the Adverse Event CRF and also reported using the procedures detailed in Section 9.5.4.1
even if the AEs do not meet serious criteria.  Abuse is always to be captured as an AE.  If the 
AE associated with an overdose, misuse, abuse, or medication error does not meet serious

criteria, it must still be reported using the SAE form and in an expedited manner but should 
be noted as nonserious on the SAE form and the Adverse Event CRF.
9.5.4.3.2
REPORTING OF STUDY-SPECIFIC EVENTS
Study-specific events (listed below) should always be considered as serious important 
medical events and be entered on the Adverse Event CRF and reported using the procedures 
detailed in Reporting of Serious Adverse Events (Section 9.5.4.1), even if the study-specific 
event does not meet other serious criteria.  

Serotonin syndrome
Must have at least 1 of the following: 
spontaneous clonus; 
inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus

Psychosis

Suicidal behavior 

Priapism

New onset of valvular heart disease

New onset pulmonary hypertension

Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas of 
the skin

Fibroadenomas of the breast or ductal carcinoma in situ
The following additional study specific AE of interest should be reported using the 
procedures detailed in Reporting of SAEs (Section 9.5.4.1), even if the study-specific 
event does not meet serious criteria.  If the event meets seriousness criteria, it should be 
reported as an SAE as above.  However, if the event listed below does not meet serious 
criteria, it should be noted as nonserious on the Adverse Event CRF:  

Suicidal ideation

Euphoria 
9.5.4.4
Expedited Reporting
The sponsor must inform investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (ie, within 
specific time frames).  For this reason, it is imperative that sites provide complete SAE 
information in the manner described above.
9.5.4.5
Breaking the Blind
In the case of a medical emergency where the appropriate treatment of the subject requires 
knowledge of the study treatment given, the investigator may break the randomization code 
for an individual subject.  In all such cases, the AE necessitating the emergency blind break 
will be handled as an SAE in accordance with the procedures indicated above.  Any broken

code will be clearly justified and documented.  The medical monitor must be notified 
immediately of the blind break.
9.5.4.6
Regulatory Reporting of Adverse Events
Adverse events will be reported by the sponsor or a third party acting on behalf of the
sponsor to regulatory authorities in compliance with local and regional law and established 
guidance.  The format of these reports will be dictated by the local and regional 
requirements.
9.5.5
Completion/Discontinuation of Subjects
The investigator may withdraw the subject from the study at any time for safety or 
administrative reasons.  A subject may elect to discontinue the study at any time for any 
reason.  All subjects will continue in the study until the 52-week evaluation is completed.  
Subjects who discontinue treatment prematurely will be followed up until study completion.  
All subjects who discontinue the study are to complete the study’s early discontinuation 
procedures indicated in the Schedule of Procedures/Assessments Table 2).
The investigator will promptly explain to the subject involved that the study will be 
discontinued for that subject and provide appropriate medical treatment and other necessary 
measures for the subject.  A subject who has ceased to return for visits will be followed up by 
mail, phone, or other means to gather information such as the reason for failure to return, the 
status of treatment compliance, the presence or absence of AEs, and clinical courses of signs 
and symptoms.
Subjects who discontinue early from the study will be discontinued for 1 of these primary 
reasons: AE(s), lost to follow-up, subject choice, withdrawal of consent, pregnancy, study 
terminated by sponsor, or other.  In addition to the primary reason, the subject may indicate
1 or more of secondary reasons for discontinuation.  Study disposition information will be 
collected on the Subject Disposition CRF.
Detailed retention strategies will be developed and included in study manual. These include 
a highly trained and competent staff, easy access to the clinic, reminder and follow-up calls, 
interactive group sessions with games and hands-on nutrition and physical activity 
demonstrations, random raffle drawings, social events, birthday and holiday cards, and
newsletters. In addition, home visits for assessments of families will be an option, as needed, 
to maximize data collection. This detailed retention plan will help prevent missing data.
A subject removed from the study for any reason may not be replaced.
9.5.6
Abuse or Diversion of Study Drug
During the study, the investigator will report any concern about abuse or diversion of study 
drugs by completing the Abuse or Diversion of Study Drug CRF.  The DEA Registrant has 
the responsibility to comply with local, state, and Federal laws to notify the Field Division 
Office of the DEA of any theft or significant loss of any controlled substances upon 
discovery of such theft or loss.

9.5.7
Confirmation of Medical Care by Another Physician
The investigator will instruct subjects to inform site personnel when they are planning to 
receive medical care by another physician.  At each visit, the investigator will ask the subject 
whether he or she has received medical care by another physician since the last visit or is 
planning to do so in the future.  When the subject is going to receive medical care by another 
physician, the investigator, with the consent of the subject, will inform the other physician 
that the subject is participating in the clinical study.
9.6
Data Quality Assurance
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines.  Site audits 
will be made periodically by the sponsor’s or the CRO’s qualified compliance auditing team, 
which is an independent function from the study team responsible for conduct of the study.
9.6.1
Data Collection
Data required by the protocol will be collected on the CRFs and entered into a validated data 
management system that is compliant with all regulatory requirements.  As defined by ICH 
guidelines, the CRF is a printed, optical, or electronic document designed to record all of the 
protocol-required information to be reported to the sponsor on each study subject.
Data collection on the CRF must follow the instructions described in the CRF Completion 
Guidelines.  The investigator has ultimate responsibility for the collection and reporting of all 
clinical data entered on the CRF.  The investigator or designee as identified on Form 
FDA 1572 must sign the completed CRF to attest to its accuracy, authenticity, and 
completeness.
Completed, original CRFs are the sole property of Eisai and should not be made available in 
any form to third parties without written permission from Eisai, except for authorized 
representatives of Eisai or appropriate regulatory authorities.
9.6.2
Clinical Data Management
All software applications used in the collection of data will be properly validated following 
standard computer system validation that is compliant with all regulatory requirements.  All 
data, both CRF and external data (eg, laboratory data), will be entered into a clinical system.
9.7
Statistical Methods
All statistical analyses will be performed by the sponsor or designee after the study is 
completed and the database is locked and released for unblinding.  Statistical analyses will be 
performed using WinNonlin and SAS software or other validated statistical software as 
required.  Details of the statistical analyses will be included in a separate statistical analysis 
plan (SAP).

who have at least 1 adequately documented measurement of BMI.
9.7.1.3
Subject Disposition
The number of subjects screened and the number (percentage) of subjects who failed 
screening and the reasons for screen failure will be summarized, based on data reported on 
the CRF.  
For study completion, the number (percentage) of treated subjects who completed study 
treatment and who discontinued from study treatment will be summarized according to the 
primary reason for discontinuation and also according to secondary reason(s) for 
discontinuation, based on data reported on the CRF.  The number (percentage) will be 
presented by treatment.  The reasons for discontinuation from study treatment will be 
documented in the CRF and source documentation.
9.7.1.4
Demographic and Other Baseline Characteristics
Demographic and other baseline characteristics for the FAS and Safety Analysis Sets will be 
summarized for each treatment group using descriptive statistics or frequency count.

Prior and Concomitant Therapy
All investigator terms for medications recorded in the CRF will be coded to an 11-digit 
character code using the World Health Organization Drug Dictionary.  The number 
(percentage) of subjects who took prior and concomitant medications will be summarized for
the Safety Analysis Set by treatment group, Anatomical Therapeutic Chemical class, and 
World Health Organization Drug Dictionary preferred term (PT).  Prior medications will be 
defined as medications that stopped before the first dose of study drug.  Concomitant 
medications will be defined as medications that started on or after the date of the dosing of 
study drug and continued up to 30 days afterward.
9.7.1.6
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, while the PP will 
be used as a supportive analysis.  Unless specified otherwise, a 2-sided α=0.05 significance 
level will be used for all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change 
from baseline in BMI will be analyzed using analysis of covariance model (ANCOVA) with 
factors of treatment, sex (male and female) as fixed effect, and the baseline age and BMI as 
covariates.  The missing values will be imputed using a pattern mixture model utilizing 
multiple imputation (MI) assuming the missing values are missing not at random (MNAR).  
The missing values will be imputed at each visit using all available values including the 
retrieved measurement from the postdiscontinuation data.  The details of the analysis model 
and missing value imputation method will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis: The same primary efficacy analyses described above will be repeated based 
on the PP.

Change from baseline in standardized BMI score (Z-score): The same primary efficacy 
analyses described above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed 
and will be described in the SAP.

Key Secondary Efficacy Analysis
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 
5% BMI reduction at Week 52.  The secondary efficacy endpoint will be analyzed only if the 
test for the primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be 
analyzed using a logistic regression model with factors of treatment, and sex (male and 
female), and baseline BMI as a covariate using FAS.  Subjects with any missing assessment 
at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be 
analyzed using mixed effect model repeated measurement analysis (MMRM) and categorical
variables will be analyzed using the Cochran Mantel Haenszel test, Chi-square test, or 
logistic regression as appropriate.  Additional analysis may be performed as needed using 
appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male 
and female), race (white, black, Asian, and other). Additional subgroups may be explored, if 
deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and 
sensitivity analyses.
9.7.1.7
Pharmacokinetic, Pharmacodynamic, Pharmacogenomic, and Other Biomarker
Analyses
9.7.1.7.1
PHARMACOKINETIC ANALYSES
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling.  The effect of covariates, such as baseline characteristics
or demographics, on PK will be explored.  Derived exposure parameters such as the 
maximum observed concentration and the area under the concentration-time curve from time
0 to 24 hours at steady-state will be calculated from the final PK model using individual 
posterior estimates of the PK parameters and from dosing history.  The PK analysis set will 
be used for this analysis.
9.7.1.7.2
PHARMACODYNAMIC ANALYSES
Change from Baseline in BMI will be assessed as the PD endpoint.  The PD analysis set will 
be used for this analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% 
and ≥10% BMI reduction, and change in waist circumference from baseline) will also be 
assessed as part of the PD analysis.  The PK/PD analysis set will be used for this analysis.

9.7.1.7.3
PHARMACOKINETIC/PHARMACODYNAMIC ANALYSES
Population PK/PD modeling will be used to explore the relationship between lorcaserin 
plasma exposure and response, including but not limited to change in BMI from baseline and 
the probability of achieving at least a 5% and at least a 10% change in BMI from baseline to 
Week 52.  Additionally, exposure-safety relationships for select safety parameters may be 
explored graphically, depending on the data at the end of study.  Any emergent relationship 
may be modeled as appropriate.  Any parameters based on the study data may be considered 
for exploratory assessment for its relationship to PK.

Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments 
including the incidence of AEs (including changes from baseline in physical examination, 
neuromuscular 
sign 
assessment, 
and 
signs 
and 
symptoms 
of 
priapism 
and 
hyperprolactinemia), out-of-normal-range laboratory safety test values, change from baseline 
in laboratory safety test values, ECGs, and vital sign measurements will be summarized by 
treatment group using descriptive statistics or frequency count as appropriate.  (revised per 
Amendment 01)
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
9.7.1.8.1
EXTENT OF EXPOSURE
Subjects will receive Belviq XR 20 mg or placebo QD for up to 52 weeks. The extent of 
exposure will be characterized by duration of exposure (in weeks) for each treatment group.
Duration of exposure will be defined as the number of weeks between the date the subject 
received the 1st dose of study drug and the date the subject received the last dose of study 
drug.  Duration of exposure will be summarized using descriptive statistics by treatment 
group.  In addition, the duration of exposure will be categorized and will be summarized 
using frequency count by treatment group.
9.7.1.8.2
ADVERSE EVENTS
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities 
(MedDRA).  Adverse events will be coded to the MedDRA (Version 18.0 or higher) lower 
level term closest to the verbatim term.  The linked MedDRA PT and primary system organ 
class (SOC) are also captured in the database.

A treatment-emergent AE (TEAE) is defined as an AE that emerges during treatment (up to 
28 days after the last dose of study drug), having been absent at pretreatment (Baseline) or 
•
Reemerges during treatment (up to 28 days after the last dose of study drug), having been 
present at pretreatment (Baseline) but stopped before treatment, or 
•
Worsens in severity during treatment relative to the pretreatment state, when the AE is 
continuous.
Only those AEs that were treatment emergent will be included in summary tables.  All AEs, 
treatment emergent or otherwise, will be presented in subject data listings.
The TEAEs will be summarized by treatment group.  The following summaries will be 
reported for TEAES:

Incidence of TEAEs in descending order of frequency

Incidence of TEAEs by SOC and PT

Incidence of treatment-related TEAEs by SOC and PT

Incidence of TEAEs by SOC, PT and maximum severity (mild, moderate, or severe)

Incidence of treatment-related TEAEs by SOC, PT, and maximum severity (mild, 
moderate, or severe)

Incidence of TEAEs by SOC, PT, and relationship to study drug (Yes [related] or No [not 
related]) 
A subject will be counted only once within a SOC or PT, if the subject experienced more 
than 1 TEAE within a specified SOC and PT.
The following summaries will also be presented for the treatment-emergent SAEs.

Incidence of TEAEs leading to death

Incidence of treatment-emergent SAE by SOC and PT

Incidence of treatment-related treatment-emergent SAE by SOC and PT
In addition, subjects with TEAEs leading to discontinuation from study drug and AEs of 
special interest as described in Section 9.5.4.3.2 will be summarized by MedDRA SOC and 
PT for each treatment group.

baseline to each postbaseline visit and to the end of treatment (defined as the last 
on-treatment value) will be summarized by visit and treatment group using descriptive 
statistics.  Percentages will be based on the number of subjects with both nonmissing 
baseline and relevant postbaseline results.
Laboratory test results will be assigned a low/normal/high (LNH) classification according to 
whether the value was below (L), within (N), or above (H) the laboratory parameter’s 
reference range.  Within-treatment comparisons for each laboratory parameter will be based 
on 3-by-3 tables (shift tables) that compare the baseline LNH classification to the LNH 
classification at the End of Treatment and the Follow-Up visits.  Similar shift tables will also 
compare the baseline LNH classification to the LNH classification for the highest and lowest 
value during the treatment period.
Appendix 1
presents the criteria that will be used to identify subjects with 
treatment-emergent markedly abnormal laboratory values (TEMAV).  Except for phosphate, 
a TEMAV is defined as a postbaseline value with an increase from baseline to a grade of 2 or 
higher.  For phosphate, a TEMAV was defined as a postbaseline value with an increase from 
baseline to a grade of 3 or higher.  When displaying the incidence of TEMAVs, each subject 
may be counted once in the laboratory parameter high and in the laboratory parameter low 
categories, as applicable.
9.7.1.8.4
VITAL SIGNS
Descriptive statistics for vital signs parameters (eg, systolic and diastolic BP, pulse, 
respiratory rate, temperature, weight) and changes from baseline will be presented by visit
and treatment group.
9.7.1.8.5
ELECTROCARDIOGRAMS
For each ECG parameter (including PR interval, RR interval, QRS interval, QT interval, QTc
interval (Bazett formula), QTc interval (Fridericia formula), and heart rate), the actual value 
and change from baseline will be summarized by visit and treatment group using descriptive 
statistics. 
Shift tables will present changes from baseline in ECG interpretation (categorized as normal; 
abnormal, not clinically significant; and abnormal, clinically significant) to end of treatment. 
Maximum postbaseline QTc (Bazett) and QTc (Fridericia) will also be tabulated by treatment 
group as follows:

Number (percentage) of subjects in greater than 450 msec, greater than 480 msec, and 
greater than 500 msec during the treatment, and

Number (percentage) of subjects with an increment of greater than 30 msec and greater 
than 60 msec from the baseline visit.

OTHER SAFETY ANALYSES
Other safety assessments including adolescent growth evaluations using 95th percentile CDC 
growth charts and bone age using x-ray of the hand, sexual maturation as measured in Tanner 
Staging, study drug effect on cognition assessed by Leiter-3, assessment of suicidality using 
C-SSRS, and depression assessment using PHQ-9 will be summarized by treatment group at 
each scheduled visit.  For echocardiographic assessments, the proportion of subjects who 
develop FDA-defined valvulopathy, the proportion of subjects who develop pulmonary 
hypertension (defined as when a subject’s SPAP is
≥40 mmHg evaluated by 
echocardiograph], and change from baseline in SPAP will also be summarized by treatment 
group at Week 28 and Week 52. (revised per Amendment 01)
9.7.2
Determination of Sample Size
The proposed sample size is based on the comparison of the primary efficacy endpoint, 
change from Baseline in BMI at Week 52 between the Belviq XR 20-mg treatment group and 
placebo group.  Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 
260 subjects in a 1:1 ratio (n=130 in the Belviq XR 20-mg treatment group; n=130 in the 
placebo group) will have at least 80% power to detect a treatment difference of 1 kg/m2 in 
BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at 
least a 5% BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, 
this sample of 260 subjects (130 subjects for Belviq XR 20 mg and 130 subjects for placebo) 
will also have greater than 78% power to detect an absolute difference of 20% between the 
Belviq XR 20-mg group and placebo group, using a 2-sided Chi-Square test with α=0.05.  
The assumption used in the sample size calculation is based on the 2 pivotal lorcaserin 
studies, APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

11 PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE 
PROCEDURES)
11.1
Changes to the Protocol
Any change to the protocol requires a written protocol amendment or administrative change 
that must be approved by the sponsor before implementation.  Amendments specifically 
affecting the safety of subjects, the scope of the investigation, or the scientific quality of the 
study require submission to health or regulatory authorities as well as additional approval by 
the applicable IRBs/IECs.  These requirements should in no way prevent any immediate 
action from being taken by the investigator, or by the sponsor, in the interest of preserving 
the safety of all subjects included in the study.  If the investigator determines that an 
immediate change to or deviation from the protocol is necessary for safety reasons to 
eliminate an immediate hazard to the subjects, the sponsor’s medical monitor and the 
IRB/IEC for the site must be notified immediately.  The sponsor must notify the health or 
regulatory authority as required per local regulations.
Protocol amendments that affect only administrative aspects of the study may not require 
submission to health or regulatory authority or the IRB/IEC, but the health or regulatory 
authority and IRB/IEC should be kept informed of such changes as required by local 
regulations.  In these cases, the sponsor may be required to send a letter to the IRB/IEC and 
the Competent Authorities detailing such changes.
11.2
Adherence to the Protocol
The investigator will conduct the study in strict accordance with the protocol (refer to ICH 
E6, Section 4.5).
11.3
Monitoring Procedures
The sponsor’s/CRO’s CRA will maintain contact with the investigator and designated staff 
by telephone, letter, or email between study visits.  Monitoring visits to each site will be 
conducted by the assigned CRA as described in the monitoring plan.  The investigator will 
allow the CRA to inspect the clinical, laboratory, and pharmacy facilities to assure 
compliance with GCP and local regulatory requirements.  The CRFs and subject’s 
corresponding original medical records (source documents) are to be fully available for 
review by the sponsor’s representatives at regular intervals.  These reviews verify adherence 
to study protocol and data accuracy in accordance with local regulations.  All records at the 
site are subject to inspection by the local auditing agency and IRB/IEC review.

when a section of the CRF itself is used as source document.  Any correction to entries made 
on the CRF must be documented in a valid audit trail where the correction is dated, the 
individual making the correct is identified, the reason for the change is stated, and the 
original data are not obscured.  Only data required by the protocol for the purposes of the 
study should be collected.
The investigator must sign each CRF.  The investigator will report the CRFs to the sponsor 
and retain a copy of the CRFs.

11.6
Retention of Records
The circumstances of completion or termination of the study notwithstanding, the 
investigator is responsible for retaining all study documents, including but not limited to the 
protocol, copies of CRFs, the Investigator's Brochure, and regulatory agency registration 
documents (eg, Form FDA 1572 ICFs, and IRB/IEC correspondence).  In addition, the 
sponsor will send a list of treatment codes by study subject to the investigator after the
clinical database for this study has been locked.  The site should plan to retain study 
documents, as directed by the sponsor, for at least 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region or at least 3 years have elapsed since the formal 
discontinuation of clinical development of the investigational product.
It is requested that at the completion of the required retention period, or should the
investigator retire or relocate, the investigator contact the sponsor, allowing the sponsor the 
option of permanently retaining the study records.
11.7
Auditing Procedures and Inspection
In addition to the routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of ICH GCP and all applicable local 
regulations.  If a government regulatory authority requests an inspection during the study or 
after its completion, the investigator must inform the sponsor immediately.
11.8
Handling of Study Drug
All study drugs will be supplied to the PI (or a designated pharmacist) by the sponsor.  Drug 
supplies must be kept in an appropriate secure area (eg, locked cabinet) and stored according 
to the conditions specified on the drug labels.  Investigational product will be stored in 
accordance with the DEA Regulations for Scheduled III - V Drugs and labeled storage 
conditions.  The investigator (or a designated pharmacist) must maintain an accurate record 
of the shipment and dispensing of the study drug in a drug accountability ledger, a copy of 
which must be given to the sponsor at the end of the study.  An accurate record of the date 
and amount of study drug dispensed to each subject must be available for inspection at any 
time.  The CRA will visit the site and review these documents along with all other study 
conduct documents at appropriate intervals once study drug has been received by the site.
All drug supplies are to be used only for this study and not for any other purpose.  The 
investigator (or site personnel) must not destroy any drug labels or any partly used or unused 
drug supply before approval to do so by the sponsor.  At the conclusion of the study and as 
appropriate during the study, the investigator (or a designated pharmacist) will return all used 
and unused drug containers, drug labels, and a copy of the completed drug disposition form 
to the sponsor’s CRA.

Family-Based Lifestyle Program
Program Overview
All subjects and their caregivers (participating parent or guardian) in Study 403 will be 
encouraged to participate in a standardized weight management program for adolescents 
consisting of multicomponent behavior therapy.  The therapy will focus on healthy eating, 
physical activity, and lifestyle changes that will facilitate weight loss and weight-loss 
maintenance. The role of the caregivers is to support their child or adolescents’ lifestyle 
changes and their taking of study medication.
The objectives of this program are as follows:

Develop a weight management program for all Belviq XR study participants and their 
caregivers (caregivers are instructed in methods to support their adolescents’ progress but 
caregivers are themselves not instructed to lose weight or take medication)

Standardize the weight management program across all study sites

Maximize participant retention

Promote participant’s adherence to both taking study medication and following the 
lifestyle program

Revised scale for measuring of 
cognition from Wide Range 
Assessment of Memory and 
Learning-2 (WRAML-2) to 
Leiter-3
Leiter-3 is selected to replace 
WRAML-2 for the evaluation of the 
change in cognition for the following 
reasons:Lack of availability of 
WRAML-2 in Spanish, Leiter-3’s 
high scientific validity, non-verbal 
format to offer less biased assessment 
for subjects whose second language is 
English, easier and shorter 
administration and short test time 
reducing investigator burden, as well 
as increase probability of the 
subjects’ retention in the study.

Study drug administration will 
be taken at approximately the 
same time each day.  On the 
days of PK sampling and the 
day before the subjects come to 
the clinic for PK sampling, 
study drug will be taken in the 
morning and doses recorded 2 
days prior to the clinic visit.
This will ensure lower variability 
with regard to PK/PD measurements.

Throughout
Prehypertension was deleted 
from the inclusion criterion.  
Subjects with Stage 1 primary 
hypertension, with an upper 
limit defined as 99% plus 5 
mmHg for age, sex, and height 
are included in the study. 
Prehypertension does not qualify as a 
comorbid condition.  The limitation 
on BP is to further define the proper 
study population.

Subjects with symptoms or 
signs of cardiac valvular disease 
or pulmonary hypertension are 
not required to have further 
evaluation by centralized 
echocardiogram assessment.  In 
addition, no adjudication will be 
performed.  Local 
echocardiograms can be 
performed if deemed medically 
necessary by the investigator.
This 
change 
allows 
for 
the 
investigator to make the decision to 
perform local echocardiograms on a 
pediatric subject if deemed medically 
indicated rather than burden the 
subject to undergo a mandated, 
unnecessary procedure.

A single dose pharmacokinetic study 
in pediatric obese subjects (APD356-
A001-026) indicated that patients with 
body weight greater than or equal to 
60 kg can be administered a dose 
similar to that given to adults and 
adolescents.  Based on Centers for 
Disease Control and Prevention 
(CDC) growth chart data, almost all 
subjects over 9 years of age are likely 
to be at or over 60 kg body weight.  
Therefore, children age 9 to 11 years 
have been included in the current 
study.

Study Design
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in obese adolescents, 
ages 12 to 17 years.  Approximately 360 subjects will be randomized in a 1:1 ratio to Belviq XR 20 mg QD
(180 subjects) and placebo (180 subjects).  Subjects will be stratified by sex.  Subjects will receive Belviq XR
20 mg or placebo QD in a 1:1 ratio for up to 52 weeks. Throughout the duration of the study, subjects will be 
encouraged to adhere to a lifestyle modification program that includes a standardized, age-appropriate diet and 
exercise counseling.
The study will consist of 2 phases: Prerandomization and Randomization.  The Prerandomization Phase will 
last up to 30 days and consist of 1 visit during which subjects will be screened for eligibility.  The 
Randomization Phase consists of a Treatment Period and a Follow-Up Period.  The Treatment Period will last 
for a maximum of 52 weeks, with visits at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52.  The Follow-Up Period will 
extend from the End of Treatment visit to the End of Study visit.
Subjects who screen fail can be re-screened only once after 60 days.  All subjects will continue in the study 
until the 52-week evaluation is completed.  Subjects who discontinue treatment prematurely will be followed up 
until study completion.  
Number of Subjects
Approximately 700 subjects will be screened to provide 360 randomized subjects.
Inclusion Criteria

Pharmacokinetic Assessments
Blood samples (approximately 4 mL each) for PK assessment will be collected at Weeks 12, 28, 36, and 52 for 
analysis of Population PK. (revised per Amendment 01)
On the day of the Week 12, 28, and 52 clinic visits, subjects will be instructed not to take their study drug at 
home before the visit,but to bring their study drug to the clinic visit, and take their daily dose at the clinic.  
Two blood samples for determination of plasma concentrations of lorcaserin will be taken: 1 predose (within 
30 minutes before dosing), and 1 within 1 to 3 hours after dosing.  Dose times must be recorded for the last 
2 dosing times before the day of clinic visit. Week 52 PK samples should only be collected if the sample can be 
drawn within 60 hours of the last dose of study drug. (revised per Amendment 01)
On the day of the Week 36 clinic visit, subjects will take their study drug in the morning at home, and will be 
asked to visit the clinic within 4 to 6 hours of dosing that day, during which 1 blood sample for for PK 
assessments will be collected. Dose times must be recorded for the last 2 dosing times prior to the clinic visit.
(revised per Amendment 01)
Pharmacodynamic Assessments

Change from baseline in BMI 

Proportion (%) of subjects achieving at least a 5% and at least a 10% reduction in BMI
Other PD endpoints will be considered based on the data at the end of the study to explore their relationships 
with lorcaserin plasma exposure.
Pharmacogenomic/Pharmacogenetic Assessments
Not applicable
Safety Assessments
Safety assessments will consist of monitoring and recording all adverse events (AEs) and serious adverse events 
(SAEs); electrocardiograms (ECGs); laboratory evaluation for hematology, metabolic function (fasting glucose, 
fasting lipids, and thyroid), adrenal function and biochemical blood and urine bone health assessments; blood 
chemistry and urine values; neuropsychiatric events; periodic measurement of vital signs, neuromuscular signs
for screening potential serotonin syndrome, and signs or symptoms of priapism and hyperprolactinemia; and 
performance of physical examinations. In patients with potential prolactin-related AEs, such as galactorrhea, 
changes in libido, or changes to menstrual cycle, prolactin level will be measured and assessed.
Other Safety Assessments
Effect on growth will be evaluated using the CDC growth chart and bone age determination by x-ray of the 
hand. Sexual maturation will be evaluated by assessing sex hormones and Tanner Staging.   
The C-SSRS will be used to assess all subjects in the study for any signal of depression or suicidal ideation or 
behavior at every visit.  Additionally, screening, diagnosing, monitoring, and measuring the severity of 
depression will be assessed using the PHQ-9 and effects on cognition will be assessed using the Leiter-3.  
(revised per Amendment 01)
Echocardiographic assessments will be used to exclude subjects with FDA-defined valvulopathy, pulmonary 
hypertension, and other major cardiovascular disease (as outlined in Exclusion Criterion No. 3) during the 
Screening Period.  Additionally, cardiac valvular function and pulmonary systolic pressure changes at Weeks
28 and 52 will be assessed. Valvular regurgitation as assessed in the echocardiogram will be rated absent, trace, 
mild, moderate, or severe for the aortic, mitral, and tricuspid valves; the rating will be absent or present for the 
pulmonic valve. The evaluations will be based on guidelines from the American Society of Echocardiography. 
Pulmonary artery pressure will be estimated from the TR jet velocity.
Bioanalytical Methods
Lorcaserin will be quantified in plasma using a validated liquid chromatography coupled with tandem mass

Analysis Sets

The Safety Analysis Set is the group of subjects who received at least 1 dose of study drug and had at least 
1 post dose safety assessment.

The Full Analysis Set (FAS) is the group of all randomized subjects regardless of adherence to study drug.

Per-Protocol Analysis Set (PP) is the group of all randomized subjects who are 80% or greater compliant 
with study medication, completed the study, have no major protocol deviations, have no violations of 
inclusion or exclusion criteria, and have BMI data at Baseline and Week 52.  The determination of subjects 
to be excluded from this population based on the above criteria and a list of major protocol violations will 
be included in the statistical analysis plan (SAP) and finalized before data base lock.

The PD Analysis Set is the group of subjects who had sufficient PD data to derive at least 1 PD parameter.

The PK Analysis Set is the group of all randomized subjects from whom at least 1 valid lorcaserin plasma 
concentration was obtained with associated documented dosing history.

The population PK/PD set is the group of randomized subjects with PK information and who have at least 
1 adequately documented measurement of BMI.
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, and the PP will be used as a 
supportive analysis.  Unless otherwise specified, a 2-sided α=0.05 significance level will be used in all efficacy 
analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change from baseline in

BMI will be analyzed using analysis of covariance model (ANCOVA) with factors of treatment,  sex (male and 
female) as fixed effect, and the baseline age and BMI as covariates.  The missing values will be imputed using a 
pattern mixture model utilizing multiple imputation (MI) assuming the missing values are missing not at 
random (MNAR).  The missing values will be imputed at each visit using all available values including the 
retrieved measurement from the postdiscontinuation data.  The details of the analysis model and missing value 
imputation method will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis:  The same primary efficacy analyses described above will be repeated based on the PP.

Change from baseline in standardized BMI score (Z-score):  The same primary efficacy analyses described 
above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed and will be
described in the SAP.
Key Secondary Efficacy Analyses
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 5% BMI reduction at 
Week 52. The secondary efficacy endpoint will be analyzed only if the test for the primary efficacy endpoint is 
statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be analyzed using a logistic 
regression model with factors of treatment, sex (male and female), and baseline BMI as a covariate using FAS.  
Subjects with any missing assessment at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be analyzed using 
mixed effect model repeated measurement analysis (MMRM) and categorical variables will be analyzed using
the Cochran Mantel Haenszel test, Chi-square test, or logistic regression as appropriate.  Additional analysis 
may be performed as needed using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male and female), and 
race (white, black, Asian, and other).  Additional subgroups may be explored, if deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and sensitivity analyses.
Pharmacokinetic Analyses
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using nonlinear mixed 
effects modeling. The effect of covariates such as baseline characteristics or demographics on PK will be 
explored. Derived exposure parameters such as the maximum observed concentration and the area under the 
concentration-time curve from time 0 to 24 hours at steady-state will be calculated from the final PK model 
using individual posterior estimates of the PK parameters and from dosing history. The PK analysis set will be 
used for this analysis.
Pharmacodynamic Analyses
Change from Baseline in BMI will be assessed as the PD endpoint.  The PD analysis set will be used for this 
analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% and ≥10% BMI 
reduction, and change in waist circumference from baseline) will also be assessed as part of the PD analysis.  
The PK/PD analysis set will be used for this analysis.
Pharmacokinetic/Pharmacodynamic Analyses
Population PK/PD modeling will be used to explore the relationship between lorcaserin plasma exposure and 
response, including but not limited to change in BMI from baseline and the probability of achieving at least a

5% and at least a 10% change in BMI from baseline to Week 52.  Additionally, exposure-safety relationships 
for select safety parameters may be explored graphically depending on the data at the end of study.  Any 
emergent relationship may be modeled as appropriate.  Any parameters based on the study data may be 
considered for exploratory assessment for its relationship to PK.
Pharmacogenomic/Pharmacogenetic Analyses
Not applicable
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments including the incidence 
of AEs (including changes from baseline in physical examination), growth (CDC growth chart and bone age 
determined by x-ray of the hand), sexual maturation (Tanner Staging), out-of-normal-range laboratory safety 
test values, change from baseline in laboratory safety test values, ECGs, and vital sign measurements will be 
summarized by treatment group using descriptive statistics or frequency count as appropriate.  
Other Safety Analyses
In addition, cognition will be evaluated by the Leiter-3, depression will be evaluated by the PHQ-9, and suicidal 
ideation and behavior will be evaluated by the C-SSRS, and will also be summarized by treatment group using 
descriptive statistics or frequency count as appropriate. For echocardiographic assessments, the proportion of 
subjects who develop FDA-defined valvulopathy, the proportion of subjects who develop pulmonary 
hypertension [pulmonary hypertension is defined when the subject’s systolic pulmonary artery pressure 
(SPAP) ≥40 mmHg evaluated by echocardiograph], and change from baseline in SPAP will be summarized by 
treatment group at Week 28 and Week 52 using descriptive statistics or frequency count as appropriate. (revised 
per Amendment 01)
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
Interim Analyses
Not applicable
Sample Size Rationale
The proposed sample size is based on the comparison of the primary efficacy endpoint, change in BMI from 
Baseline to Week 52 between the Belviq XR 20-mg treatment group and placebo group.  Assuming a SD of 
2.2 kg/m2 and a 40% dropout rate, a sample size of 360 subjects in a 1:1 ratio (n=180 in the Belviq XR 20-mg 
treatment group; n=180 in the placebo group) will have at least 90% power to detect a treatment difference of 
1 kg/m2 in BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at least a 5% 
BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, this sample of 360 subjects 
(180 subjects for Belviq XR 20 mg and 180 subjects for placebo) will also have greater than 85% power to 
detect an absolute difference of 20% between the Belviq XR 20-mg group and the placebo group, using a 2-
sided Fisher’s Exact test with α=0.05. The assumption used in the sample size calculation is based on the 
2 pivotal lorcaserin studies APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

ETHICS
5.1
Institutional Review Boards/Independent Ethics Committees
The protocol, Informed Consent Form (ICF), and appropriate related documents must be 
reviewed and approved by an Institutional Review Board (IRB) or Independent Ethics 
Committee (IEC) constituted and functioning in accordance with International Conference on 
Harmonisation (ICH) Good Clinical Practice (ICH E6), Section 3, and any local regulations 
(eg, Federal Regulations, Title 21 Code of Federal Regulations [21 CFR] Part 56).  Any 
protocol amendment or revision to the ICF will be resubmitted to the IRB/IEC for review and 
approval, except for changes involving only logistical or administrative aspects of the study 
(eg, change in clinical research associate [CRA], change of telephone number[s]).  
Documentation of IRB/IEC compliance with the ICH E6 and any local regulations regarding 
constitution and review conduct will be provided to the sponsor.
A signed letter of study approval from the IRB/IEC chairman must be sent to the principal 
investigator (PI) with a copy to the sponsor before study start and the release of any study 
drug to the site by the sponsor or its designee (ICH E6, Section 4.4).  If the IRB/IEC decides 
to suspend or terminate the study, the investigator will immediately send the notice of study 
suspension or termination by the IRB/IEC to the sponsor.
Study progress is to be reported to IRB/IECs annually (or as required) by the investigator or 
sponsor, depending on local regulatory obligations.  If the investigator is required to report to 
the IRB/IEC, he/she will forward a copy to the sponsor at the time of each periodic report.  
The investigator(s) or the sponsor will submit, depending on local regulations, periodic 
reports and inform the IRB/IEC of any reportable adverse events (AEs) per ICH guidelines 
and local IRB/IEC standards of practice.  Upon completion of the study, the investigator will 
provide the IRB/IEC with a brief report of the outcome of the study, if required.
At the end of the study, the sponsor should notify the IRB/IEC and Competent Authority 
within 90 days.  The end of the study will be the date of the last study visit for the last subject 
in the study.  The sponsor should also provide the IRB/IEC with a summary of the study’s 
outcome.
In the case of early termination or a temporary halt of the study, the investigator should 
notify the IRB/IEC and Competent Authority within 15 calendar days, and a detailed written 
explanation of the reasons for the termination/halt should be given.

Ethical Conduct of the Study
This study will be conducted in accordance with standard operating procedures (SOPs) of the 
sponsor (or designee), which are designed to ensure adherence to GCP guidelines as required 
by the following:
•
Principles of the World Medical Association Declaration of Helsinki 2013
•
ICH E6 Guideline for GCP (CPMP/ICH/135/95) of the European Agency for the 
Evaluation of Medicinal Products, Committee for Proprietary Medicinal Products, 
International Conference on Harmonisation of Pharmaceuticals for Human Use
•
Title 21 of the United States Code of Federal Regulations (US 21 CFR) regarding clinical 
studies, including Part 50 and Part 56 concerning informed subject consent and IRB 
regulations and applicable sections of US 21 CFR Part 312
5.3
Subject Information and Informed Consent
As part of administering the informed consent document, the investigator must explain to 
each subject and guardian/legally authorized representative the nature of the study, its 
purpose, the procedures involved, the expected duration, the potential risks and benefits 
involved, any potential discomfort, potential alternative procedure(s) or course(s) of 
treatment available to the subject, and the extent of maintaining confidentiality of the 
subject’s records.  Each subject must be informed that participation in the study is voluntary, 
that he/she may withdraw from the study at any time, and that withdrawal of consent will not 
affect his/her subsequent medical treatment or relationship with the treating physician.
This informed consent should be given by means of a standard written statement, written in 
nontechnical language.  The subject or the subject’s legally acceptable representative should 
understand the statement before signing and dating it and will be given a copy of the signed 
document.  If a subject is unable to read or if a legally acceptable representative is unable to 
read, an impartial witness should be present during the entire informed consent discussion.  
After the ICF and any other written information to be provided to subjects is read and 
explained to the subject or the subject’s legally acceptable representative, and after the 
subject or the subject’s legally acceptable representative has orally consented to the subject’s 
participation in the study and, if capable of doing so, has signed and personally dated the 
ICF, the witness should sign and personally date the consent form.  The subject will be asked 
to sign an ICF before any study-specific procedures are performed.  No subject can enter the 
study before his/her informed consent has been obtained.  The adolescent participant will 
provide written assent and the caregiver/guardian will provide written informed consent.
An unsigned copy of an IRB/IEC-approved ICF must be prepared in accordance with 
ICH E6, Section 4, and all applicable local regulations (Federal Regulations, 
Title 21 CFR Part 50, for studies in the United States).  Each subject must sign an approved 
ICF before study participation.  The form must be signed and dated by the appropriate 
parties.  The original, signed ICF for each subject will be verified by the sponsor and kept on 
file according to local procedures at the site.

INTRODUCTION
7.1
Indication
Obesity has become a global epidemic, causing a serious public health concern.  In the 
United States, the prevalence of obesity in adolescents ages 12 and 19 years has almost 
doubled over the past 2 decades.  The rate increased from 10.5% between 1988 and 1994 to 
20.5% between 2011 and 2012 (CDC/NCHS, 2013).  Obesity in adolescents, defined in the 
United States as greater than or equal to the 95th percentile in gender- and age-specific body 
mass index (BMI), continues to grow at an alarming rate in the United States and globally.  
Based on data (Wang and Lobstein, 2006) using various criteria for the definition of obesity 
that included more than 30 countries in Europe, North America, Asia, and the West Pacific, 
prevalence of obesity in these countries has also increased significantly, at a rate comparable 
to that in the United States.
Adolescent obesity has many negative implications for both the health and well-being of the 
individual as well as for society.  These include increased susceptibility to a host of diseases, 
chronic health disorders, psychological disorders, and premature death (Flegal, et al., 2005; 
Rofey, et al., 2009).  Increases in the prevalence of overweight and obese adolescents may 
result in a decrease in life expectancy for the 1st time in 200 years (Peeters, et al., 2003).
As a result, there is a significant impact on the cost of healthcare.  It is estimated that medical 
costs due to overweight adolescents are approximately $14 billion per year in the United 
States (Trasande and Chatterjee, 2009).  Obesity-related medical costs in general are
expected to rise significantly because today’s obese adolescents are likely to become 
tomorrow’s obese adults (Whitaker, et al., 1997).
Current approaches to weight management in adults include lifestyle modification, 
pharmacotherapy, and invasive bariatric procedures.  Lifestyle modification involves a 
combination of diet, exercise, and behavioral change, and is the preferred and essential 
strategy for weight management in obese and overweight individuals, including adolescents.  
Although lifestyle modification can be very efficacious in some patients, adherence to the 
prescribed regimens is often poor.  As such, lifestyle modification alone is often not adequate 
and the weight loss is often transient.  On the other hand, bariatric surgery and various other 
invasive procedures are generally reserved for the severely obese population. 
Pharmacotherapy can play a significant role in weight management programs, and is often 
combined with lifestyle modification to enhance weight loss beyond that which is normally 
achieved with diet and exercise alone.  Current pharmacotherapies offer the potential to 
significantly augment weight loss when combined with diet and exercise, but are rarely used 
for adolescents.
The current standard of care for treatment of obesity in adolescent subjects ranges from
behavioral therapy including lifestyle intervention to the rare use of pharmacotherapy in 
adolescents over 12 years of age (McGovern, et al, 2008; Spear, et al, 2007).  Xenical®
(orlistat) is currently the only product available for weight control in obese adolescent 
patients 12 to 16 years of age.  However, it is associated with gastrointestinal side effects

(Xenical PI. 2015), and the treatment effect of Xenical is modest. In a study that included 
539 obese adolescents with BMI above the 97th percentile, Xenical demonstrated a 0.86 BMI 
reduction relative to placebo after 52 weeks of treatment (-0.55 BMI in the Xenical treatment 
group versus +0.31 BMI in the placebo group) (FDA, 2003; Chanoine, et al, 2005).
Obtaining maximum retention in the study is a major goal in order to minimize missing data.  
A number of strategies have been used in prior adolescent weight loss studies that will be 
used in the present study to help retain participants.  These include a highly trained and 
competent staff, ample waiting area, readily available parking (at no cost), access to mass 
transit, and reminder and follow-up calls.  In addition, we will provide fun and interactive 
group sessions with games and hands-on nutrition and physical activity demonstrations, 
random raffle drawings, social events, birthday and holiday cards, and newsletters.  
Furthermore, we will make home visits for assessments of families, as needed, to maximize 
data collection. 
By using these retention strategies, we hope that we will maximize 
participant retention, which will help us cope with missing data.
7.1.1
APD356/Belviq (lorcaserin hydrochloride)
7.1.1.1
Mechanism of Action
Belviq is a selective serotonin 2c receptor agonist which was approved by the US Food and 
Drug Administration (FDA) on 27 Jun 2012 as an adjunct to a reduced-calorie diet and 
increased physical activity for chronic weight management in adult patients with a BMI of at 
least 30 kg/m2 (obese), or adult patients with a BMI greater than or equal to 27 kg/m2
(overweight) in the presence of at least 1 weight-related comorbid condition.
7.1.1.2
Clinical Experience with APD356/Belviq (lorcaserin hydrochloride)
The Phase 3 clinical evaluation of Belviq in studies of more than 7700 adult subjects, 
including 604 subjects with Type 2 diabetes mellitus, demonstrated clinically meaningful 
efficacy and a safety profile that includes minimal and easily managed risks.  In each of the 
individual studies and in the pooled efficacy analyses, the Belviq dose met the following 
prespecified endpoints:

A significantly greater proportion of adult subjects taking Belviq 10 mg twice per day 
(BID) (47%) lost at least 5% of baseline body weight at 52 weeks as compared to 
subjects taking placebo (23%).  A significantly greater proportion of subjects taking 
Belviq 10 mg BID (22.4%) lost at least 10% of baseline body weight at 1 year as 
compared to subjects taking placebo (8.7%). 

The mean weight loss at 1 year in adult subjects taking Belviq 10 mg BID (-5.8 kg) was 
significantly greater than that in subjects taking placebo (-2.5 kg).
An integrated evaluation of the data from the pediatric, adolescent, and adult subjects 
revealed that the relationship between lorcaserin area under the curve (AUC) and body 
weight in pediatric and adult subjects is consistent irrespective of the individual studies or 
age range of the study population. Irrespective of age, lorcaserin AUC values in the pediatric 
subjects with body weight of greater than 60 kg overlapped with the data observed from the 
studies involving adult subjects, suggesting a fixed dose approach similar to adults can be

used for adolescent subjects with body weight greater than 60 kg.
In adolescent obese populations, it is anticipated that Belviq XR will result in similar effects.
As part of FDA postmarketing requirements, this study is designed to characterize the 
efficacy and safety of Belviq XR in adolescent obese populations in the United States.  It is 
also intended to support an indication for chronic weight management for obese adolescents 
ages 12 to 17 years old. 
7.1.2
Study Rationale
There is no specific FDA guidance for the approval of a weight loss product for adolescents.  
In adults, the Division’s 2007 draft Guidance for Industry Developing Products for Weight 
Management indicate that the product needs to satisfy either of the following mean or 
categorical criteria after 1 year of treatment:

The difference in mean weight loss between the active-product and placebo-treated 
groups is at least 5% and the difference is statistically significant.

The proportion of subjects who lose at least 5% of baseline body weight in the 
active-product group is at least 35%, is approximately double the proportion of subjects 
in the placebo-treated group who lose at least 5% of baseline body weight, and the 
difference between groups is statistically significant.
FDA awarded a weight management indication for Belviq based on Phase 3 study results 
which achieved the categorical criteria. In a Phase 3 study, a significantly greater proportion 
of subjects taking Belviq (47%) lost at least 5% of baseline body weight at 1 year as 
compared to subjects taking a placebo (23%).  It is anticipated that a similar effect will be 
demonstrated in obese adolescents, where weight loss will be assessed using BMI
measurements to account for growth. In this study, the objective is to demonstrate that BMI
reduction will be achieved during 52 weeks of treatment with Belviq XR 20 mg administered 
once daily (QD) compared to placebo in obese adolescents.
In the Phase 3 orlistat study in obese adolescents mentioned above, the proportion of subjects 
who lost at least 5% body weight is relatively low. At the end of the study at Week 52, only 
26.5% of the subjects achieved a 5% or greater BMI reduction compared to 15.7% in the 
placebo group. The placebo-corrected BMI reduction was about 0.86 kg/m2.  
There are limited trials for weight reduction in the adolescent population, ages 12 to 17 years
(Peirson, et al, 2015).  Thirty-one studies (29 behavioral, 2 pharmacological and behavioral) 
were included in a meta-analysis of randomized studies conducted in primary care centers in 
overweight and obese children and youth ages 2 to 18 years using behavioral (diet, exercise,
and lifestyle) and pharmacological interventions and providing 6-month postbaseline BMI or 
prevalence of overweight or obesity. Both interventions showed a significant effect on BMI 
in favor of treatment (behavioral: 
standardized mean difference [SMD] -0.54, 
95% confidence interval [CI]
-0.73, -0.36; orlistat plus behavioral: 
SMD -0.43, 
95% CI -0.60, -0.25). The studies reported no significant difference between groups in the 
likelihood of reduced prevalence of overweight or overweight and obese. A great deal of 
variation was noted across efficacious interventions.
In conclusion, this meta-analysis

demonstrated low-quality evidence that behavioral treatments alone are associated with a 
smaller effect in terms of reduced BMI compared with the effect shown by combined 
behavioral and pharmacological interventions. This may be because the effect size in the 
randomized, double blind, placebo controlled, phase 3 orlistat study in adolescents was 
relatively low and there was a lack of maintenance effect. These subjects started to regain 
their BMI after 6 months of treatment. At end of the study, only 26.5% of subjects achieved 
a 5% or greater BMI reduction compared to 15.7% in placebo group. In a sibutramine 
Phase 3 study in obese adolescents, a substantially higher proportion of subjects (69%) 
treated with sibutramine achieved at least a 5% BMI reduction compared to 21% of subjects 
in the placebo group. In addition, sibutramine resulted in a substantial reduction in mean 
BMI (between-group difference, 2.9 kg/m2) and mean weight (between-group difference, 
8.4 kg) compared to placebo (Berkowitz, et al, 2006).  Unlike the weight loss effect of Belviq
in adults and sibutramine in adolescents, subjects in the orlistat study started to increase their 
BMI after 6 months of treatment.
In this study, it is assumed that treatment with Belviq XR 20 mg will lead to a BMI reduction
of more than 1 kg/m2, and a higher proportion of subjects will achieve more than a 5% and 
10% BMI reduction compared to placebo.  A between-group difference of 24% is the basis 
for the conservative assumption of a 20% effect size in the current study.
In addition, the total sample size of 360 subjects will be adequate to assess safety and 
exposure based on previous adolescent studies with weight management products (orlistat 
and sibutramine) (FDA, 2003; Chanoine, et al, 2005; Berkowitz, et al, 2006) and other 
metabolic or dyslipidemia medication products (ezetimibe, simvastatin) (FDA, 2007).

INVESTIGATIONAL PLAN
9.1
Overall Study Design and Plan
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in 
obese adolescents ages 12 to 17 years.  Approximately 360 subjects will be randomized in a 
1:1 ratio to Belviq XR 20 mg QD (180 subjects) and placebo (180 subjects).  Subjects will be 
stratified by sex.  Subjects will receive Belviq XR 20 mg or placebo QD in a 1:1 ratio for up 
to 52 weeks. Throughout the duration of the study, subjects will be encouraged to adhere to 
a lifestyle modification program that includes a standardized, age-appropriate diet and 
exercise counseling (see Appendix 2).  
The study will consist of 2 phases:
Prerandomization and Randomization.  The 
Prerandomization Phase will last up to 30 days and consists of 1 visit during which subjects 
will be screened for eligibility.  The Randomization Phase consists of a Treatment Period and 
a Follow-Up Period.  The Treatment Period will last for a maximum of 52 weeks, with visits 
at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52; the Follow-Up Period will extend from the 
End of Treatment (EOT) visit to the End of Study (EOS) visit.
Subjects who screen fail can be rescreened only once after 60 days.  All subjects will 
continue in the study until the 52-week evaluation is completed.  Subjects who discontinue 
treatment prematurely will be followed up until study completion.
9.1.1
Prerandomization Phase
Screening will occur during the Prerandomization Phase at Visit 1.
9.1.1.1
Screening Period
The purpose of the Screening Period is to obtain the informed consent and assent and to 
establish protocol eligibility.  Procedures to be followed when obtaining informed consent 
are detailed in Section 5.3.  Careful initial screening is important in the recruitment of 
families who both fully understand the requirements of this 1 year, randomized, controlled 
trial and are truly interested in participation.  Interested caregivers and adolescents will be 
screened by phone to assess preliminary entry criteria.  Candidates will be given a brief 
description of the program and general study requirements, with an adolescent and a 
caregiver who is willing to participate.  If preliminary entry criteria are met, adolescents and 
their caregivers will be invited to an initial in-clinic meeting to further discuss the study.  A 
complete description of the study including assessments, the number of visits, the lifestyle 
program, the fact that the adolescent would be taking either the study drug or a placebo, the
duration of the study, and the necessity of having an adolescent wishing to participate as well 
as a participating caregiver will be described.  Consent and assent will be obtained and copies 
of the signed forms will be provided to families.  The importance of the study and its 
scientific merit will be discussed.  Ineligible adolescents will be referred to local weight 
management resources.  Screening period assessments and timing thereof are shown in 
Section 9.5.2.

Discussion of Study Design, Including Choice of Control Groups
The proposed dose and dosing frequency of Belviq XR in this study is 20 mg QD.  The PK 
parameters of a single 10-mg dose of Belviq were evaluated in healthy, adolescent obese 
subjects in Study APD356-025.  Overall, the PK parameters of Belviq and its main 
metabolites, M1 and M5, were similar to those in adults.  Following a single, oral 
administration of Belviq 10 mg to a total of 8 healthy adolescent (ages 12 to 17 years old) 
obese subjects, the mean maximum concentration observed and the area under the 
concentration-time curve from time zero to infinity (AUC(0-inf)) were 36.5 ng/mL and 
464 hr×ng/mL, respectively.  The mean Belviq terminal phase half-life was 9.70 hours, 
similar to that observed in adults, thus supporting a similar dosing frequency (QD) in 
adolescent subjects.
Additionally, a single dose PK study in 8 healthy obese pediatric subjects ages 6 to 11 years 
of age was performed. The PK analysis after a single 10-mg dose of lorcaserin revealed that 
the lorcaserin AUC(0-inf) values tended to increase with decreasing body weight and age.
However, the body weight normalized AUC(0-inf) values were similar across the age groups, 
therefore the data indicated no effect of age on the lorcaserin PK. Integrated assessment of 
the PK versus body weight relationship, pooling the data from pediatric and adult subjects 
from previous studies, suggested that the lorcaserin area under the curve values for subjects 
with body weight of at least 60 kg overlapped with the area under the curve values from 
adolescents and adults. Therefore, no dose adjustment relative to adults and adolescents is 
deemed necessary for pediatric or adolescent subjects with a body weight of at least 60 kg.
Based on CDC growth charts, the likelihood of subjects who are older than 12 years of age 
having a body weight of less than 60 kg is very low; therefore, the current study as designed 
to enroll subjects between 12 to 17 years of age with body weight at least 60 kg, will cover
majority of the population of interest.  The targeted study population comprises 360 obese 
adolescents 12 to 17 years of age, with a body weight at least 60 kg.
Obese adolescents will be identified using gender- and age-specific BMI measurement.  
Obesity in adolescents is defined by US Expert committee recommendations as BMI in or 
above the 95th percentile (Barlow, 2007).

Randomization will be used in this study to avoid bias in the assignment of subjects to 
treatment, to increase the likelihood that known and unknown subject attributes 
(eg, demographics, baseline characteristics) are balanced across treatment groups, and to 
ensure the validity of statistical comparisons across treatment groups.  Blinding to treatment 
will be used to reduce potential bias during data collection and evaluation of endpoints.
9.3
Selection of Study Population
Approximately 700 subjects will be screened to ensure that 360 subjects will be randomized.
Subjects who do not meet all inclusion criteria or do meet any exclusion criteria will not be

Method of Assigning Subjects to Treatment Groups
Subjects will be assigned to treatments based on a computer-generated randomization 
scheme that will be reviewed and approved by an independent statistician.  The 
randomization scheme and identification for each subject will be included in the final clinical 
study report for this study.
Subjects will be centrally stratified by sex (male and female).  Within each stratum, subjects 
will be randomized to receive either Belviq XR 20 mg or placebo QD in a 1:1 ratio.  
Randomization will be performed centrally by an interactive voice or web response system 
(IxRS).  The IxRS or clinical supply vendor will generate the randomized identification
numbers to be included on study packaging.  Upon signature of the ICF, the investigator or 
designee will access the IxRS to register the subject information.  At Randomization, the 
IxRS will assign each subject a unique randomization number.  At each subsequent visit 
during the Treatment Period and Follow-Up Period, the investigator or designee will access 
IxRS to obtain dispensing information and to register the subject’s visit.
9.4.4
Selection and Timing of Dose for Each Subject
Subjects should take the study medication once daily at approximately the same time of 
every day, and be encouraged to take the study medication with an adequate amount of water 
(8 oz. or 240 mL).
9.4.5
Blinding
During the Randomization Phase, subjects and all personnel involved with the conduct and 
interpretation of the study, including investigators, site personnel, and sponsor staff will be 
blinded to the treatment codes.  Randomization data will be kept strictly confidential, filed 
securely by an appropriate group with the sponsor or CRO, and accessible only to authorized 
persons (eg, Eisai Global Safety) until the time of unblinding, per the SOP.
A master list of all treatments and the subject numbers associated with them will be 
maintained in a sealed envelope by the clinical supply vendor, the IxRS vendor, and the 
sponsor.  In the event that emergency conditions require knowledge of the study treatment 
given, the blind may be broken via the code breaker facility within the IxRS.  Emergency 
procedures for revealing drug codes are given in Section 9.5.4.5.  If possible, before breaking 
the blind, the investigator should consult with the sponsor or designee to ascertain the 
necessity of breaking the code.
9.4.6
Prior and Concomitant Therapy
Any medication (including OTC medications) or therapy administered to the subject during 
the study (starting at the date of informed consent) will be recorded on the Prior and
Concomitant Medication Case Report Form (CRF) or Non-Pharmacological Procedures 
CRF.  The investigator will record on the Adverse Event CRF any AE for which the 
concomitant medication/therapy was administered. If the concomitant medication/therapy is

9.5.1.5.1
ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered an investigational product.  An AE does not necessarily have a causal 
relationship with the medicinal product.  For this study, the study drug is Belviq XR
(lorcaserin hydrochloride).
The criteria for identifying AEs in this study are:
•
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or

Page 41 of 78
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE)
•
Any new disease or exacerbation of an existing disease 
•
Any deterioration in non-protocol-required measurements of a laboratory value or other 
clinical test (eg, ECG, x-ray) that results in symptoms, a change in treatment, or 
discontinuation of study drug
•
Recurrence of an intermittent medical condition (eg, headache) not present pretreatment 
(Baseline)
•
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of study drug, or withholding 
of study drug, whether prescribed in the protocol or not.
All AEs observed during the study will be reported on the Adverse Event CRF.  All AEs, 
regardless of relationship to study drug or procedure, should be collected beginning from the 
time the subject signs the study ICF through the last visit in the Treatment Phase.  Subjects 
who fail screening primarily due to AE(s) must have the AE(s) leading to screen failure 
reported on the Screening Disposition CRF.  SAEs will be collected for 28 days after the last 
dose.
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute 
an AE.  Medical and scientific judgment should be exercised in deciding whether an isolated 
laboratory abnormality should be classified as an AE.  Any laboratory abnormality 
considered to constitute an AE should be reported on the Adverse Event CRF. 
Abnormal ECG (corrected QT interval [QTc]) results, if not otherwise considered part of a 
clinical symptom that is being reported as an AE, should be considered an AE if the QTc 
interval is greater than 450 msec and there is an increase of more than 60 msec from baseline.  
Any ECG abnormality that the investigator considers as an AE should be reported as such.
It is the responsibility of the investigator to review the results of the Leiter-3, C-SSRS, and 
PHQ-9 for all subjects and determine if any result constitutes an AE.  Medical and scientific 
judgment should be exercised in deciding whether an isolated suicidality rating scale 
response should be classified as an AE (see Section 9.5.1.5.10 for a description of the 
C-SSRS).  (revised per Amendment 01)
All AEs must be followed for 28 days after the subject’s last dose or until resolution, 
whichever comes first.  All SAEs must be followed to resolution or, if resolution is unlikely, 
to stabilization.
Every effort must be made by the investigator to categorize each AE according to its 
severity and its relationship to the study treatment.

Assessing Severity of Adverse Events
Adverse events will be graded on a 3-point scale (mild, moderate, severe) and reported in the 
detail indicated on the CRF.  The definitions are as follows:
Mild
Discomfort noticed, but no disruption of normal daily activity
Moderate Discomfort sufficient to reduce or affect normal daily activity
Severe
Incapacitating, with inability to work or to perform normal daily activity
The criteria for assessing severity are different than those used for seriousness (see
Section 9.5.1.5.2 for the definition of an SAE).
Assessing Relationship to Study Treatment
Items to be considered when assessing the relationship of an AE to the study treatment are:
•
Temporal relationship of the onset of the event to the initiation of the study treatment
•
The course of the event, especially the effect of discontinuation of study treatment or 
reintroduction of study treatment, as applicable
•
Whether the event is known to be associated with the study treatment or with other 
similar treatments
•
The presence of risk factors in the study subject known to increase the occurrence of the 
event
•
The presence of nonstudy, treatment-related factors that are known to be associated with 
the occurrence of the event
Classification of Causality
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question:
Is there a reasonable possibility that the study drug caused the AE?
Yes (related)
A causal relationship between the study drug and the AE is a reasonable 
possibility.
No (not related) A causal relationship between the study drug and the AE is not a 
reasonable possibility.
9.5.1.5.2
SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An SAE is any untoward medical occurrence that at any dose:
•
Results in death

•
Is life-threatening (ie, the subject was at immediate risk of death from the AE as it 
occurred; this does not include an event that, had it occurred in a more severe form or 
was allowed to continue, might have caused death)
•
Requires inpatient hospitalization or prolongation of existing hospitalization
•
Results in persistent or significant disability/incapacity
•
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug)
Other important medical events that may not be immediately life-threatening or result in 
death or hospitalization but, when based on appropriate medical judgment, may jeopardize 
the subject or may require intervention to prevent one of the outcomes in the definition of 
SAE listed above should also be considered SAEs.  Medical and scientific judgment should 
be exercised in deciding whether expedited reporting is appropriate in such situations. 
For this study, the following events should always be considered serious and reported as an 
important medical event if it does not meet other serious criteria:
•
Serotonin syndrome (must have at least 1 of the following: 
Spontaneous clonus; 
Inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus)
•
Psychosis
•
Suicidal behavior
•
Priapism
•
New onset valvular heart disease
•
New onset pulmonary hypertension
•
Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas of 
the skin
•
Fibroadenomas of the breast or ductal carcinoma in situ
The following additional study specific AE of interest should be reported using the 
procedures detailed in Reporting of SAEs (Section 9.5.4.1), even if the study specific event 
does not meet serious criteria.  If the event meets seriousness criteria, it should be reported as 
an SAE as above.  However, if the event listed below does not meet serious criteria, it should 
be noted as nonserious on the Adverse Event CRF:  
•
Suicidal ideation   
•
Euphoria 
In addition to the above, events associated with special situations include pregnancy or 
exposure to study drug through breastfeeding; AEs associated with study drug overdose,

misuse, abuse, or medication error.  These events associated with special situations are to be 
captured using the SAE procedures but are to be considered as SAEs only if they meet 1 of 
the above criteria.  All AEs associated with special situations are to be reported on the CRF 
whether or not they meet the criteria for SAEs.  
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization.
The following hospitalizations are not considered to be SAEs because there is no “AE” (ie, 
there is no untoward medical occurrence) associated with the hospitalization:
•
Hospitalizations for respite care
•
Planned hospitalizations required by the protocol  
•
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed after study drug administration)
•
Hospitalization for administration of study drug or insertion of access for administration 
of study drug
•
Hospitalization for routine maintenance of a device (eg, battery replacement) that was in
place before study entry

split (or 2 samples drawn) to allow a local laboratory analysis in addition to the central 
laboratory.  
A laboratory abnormality may meet the criteria to qualify as an AE as described in this 
protocol (see Section 9.5.1.5.1) and the CRF Completion Guidelines.  In these instances, the 
AE corresponding to the laboratory abnormality will be recorded on the Adverse Event CRF.
9.5.1.5.4
VITAL SIGNS AND WEIGHT MEASUREMENTS

9.5.1.5.10 OTHER SAFETY ASSESSMENTS
Leiter-3
The Leiter International Performance Scale–Third Edition (Leiter-3) is widely used 
non verbal measure of intelligence, memory, and attention in those between the ages of 3 and 
75 years. 
The Attention/Memory Battery consists of 5 subtests: 2 measure nonverbal 
attention; 2 measure memory; and 1 measures cognitive interference (nonverbal Stroop test). 
These subtests are combined to produce a Memory and Processing Speed composite scores, 
normalized to a mean of 100 and standard deviation of 15. The Leiter-3 will be used to 
assess lorcaserin effects on cognition, specifically, attention and memory. In addition, signs 
and symptoms of cognition-related AEs, including impairments in attention, memory, and 
adverse effects on schoolwork will be captured in the eCRF. (revised per Amendment 01)
PHQ-9
The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and 
measuring the severity of depression:

The PHQ-9 incorporates Diagnostic and Statistical Manual of Mental Disorders, 4th 
Edition (DSM-IV) depression diagnostic criteria with other leading major depressive 
symptoms into a brief self-report tool.

The tool rates the frequency of the symptoms which factors into the scoring severity 
index.

Question 9 on the PHQ-9 screens for the presence and duration of suicide ideation.

A follow-up, non-scored question on the PHQ-9 assigns weight to the degree to which 
depressive problems have affected the patient's level of function. 
C-SSRS
The C-SSRS collects information pertinent to suicidal ideation and actions.  It consists of a 
Baseline version which will be administered at baseline and a Since Last Visit version which 
will be administered at the remaining visits.  C-SSRS will be used to assess signal of 
depression and suicidal ideation or behavior. Qualified personnel must evaluate positive 
responses on the C-SSRS and take appropriate action as detailed in the training and 
certification process for administering the C-SSRS.  It will be performed at Screening and at 
study visits as designated in the Schedule of Procedures/Assessments (Table 2). (revised per 
Amendment 01)

Tanner Staging
The pubic hair growth (both sexes), genital (males only) and breast (females only) 
development of subjects will be using Tanner Staging (Marshall, 1970). Subjects will be 
examined by the investigator as designated in the Schedules/Assessments (Table 2). (revised 
per Amendment 01)
Echocardiogram
Echocardiograms will be obtained on the Schedule of Procedures/Assessments (Table 2). 
Valvular regurgitation in echocardiogram will be rated absent, trace, mild, moderate, or 
severe for the aortic, mitral, and tricuspid valves; the rating will be absent or present for the 
pulmonic valve.  The evaluations will be based on guidelines from the American Society of 
Echocardiography. Pulmonary artery pressure will be estimated from the TR regurgitant jet 
velocity.

Reporting of Serious Adverse Events, Pregnancy, and Events Associated 
with Special Situations
9.5.4.1
Reporting of Serious Adverse Events
All SAEs, regardless of their relationship to study treatment, must be reported on a 
completed SAE form by email or fax as soon as possible but no later than 1 business 
day from the date the investigator becomes aware of the event.
SAEs, regardless of causality assessment, must be collected through the through the last visit
and for 28 days after the subject’s last dose.  All SAEs must be followed to resolution or, if 
resolution is unlikely, to stabilization.  Any SAE judged by the investigator to be related to 
the study treatment or any protocol-required procedure should be reported to the sponsor 
regardless of the length of time that has passed since study completion.
The detailed contact information for reporting of SAEs is provided in the Investigator Study 
File.
For urgent safety issues, please ensure all appropriate medical care is administered to the 
subject and contact the appropriate study team member listed in the Investigator Study File.
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report.  This includes the investigator’s assessment of causality.
Any follow-up information received on SAEs should be forwarded within 1 business day of 
its receipt.  If the follow-up information changes the investigator’s assessment of causality, 
this should also be noted on the follow-up SAE form.
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested by 
the sponsor.
The investigator must notify his/her IRB/IEC of the occurrence of the SAE, in writing, if 
required by their institution.  A copy of this communication must be forwarded to the sponsor 
to be filed in the sponsor’s Trial Master File.
9.5.4.2
Reporting of Pregnancy and Exposure to Study Drug through Breastfeeding
Any pregnancy in which the estimated date of conception is either before the last visit or 
within 28 days of last study treatment or any exposure to study drug through breastfeeding 
during study treatment or within 28 days of last study treatment must be reported.
If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, this 
should be reported regardless of the length of time that has passed since the exposure to study 
treatment.

A congenital anomaly, death during perinatal period, an induced abortion, or a spontaneous 
abortion are considered to be an SAE and should be reported in the same time frame and in 
the same format as all other SAEs (see Section 9.5.4.1).
Pregnancies or exposure to study drug through breastfeeding must be reported by fax or 
email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy.  The contact information for the reporting of pregnancies 
and exposure to study drug through breastfeeding is provided in the Investigator Study File.  
The Pregnancy Report Form must be used for reporting.  All pregnancies must be followed to 
outcome.  The outcome of the pregnancy must be reported as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the outcome.
A subject who becomes pregnant must be withdrawn from the study. 
9.5.4.3
Reporting of Events Association with Special Situations
9.5.4.3.1
REPORTING OF ADVERSE EVENTS ASSOCIATED WITH STUDY DRUG OVERDOSE,
MISUSE, ABUSE, OR MEDICATION ERROR
Adverse events associated with study drug overdose, misuse, abuse, and medication error 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication error are defined as follows:
Overdose
Accidental or intentional use of the study drug in an amount higher
than the protocol-defined dose
Misuse
Intentional and inappropriate use of study drug not in accordance with 
the protocol or authorized dose, route of administration, or 
indication(s) or use of prescription-only study drug without a 
prescription
Abuse
Sporadic or persistent intentional excessive use of study drug 
accompanied by harmful physical or psychological effects
Medication error
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of the 
healthcare professional, subject, or consumer.  Such events may be 
related to professional practice, healthcare products, occupational 
exposure, procedures, or
systems,
including prescribing,
order 
communication,
product
labeling, 
packaging, 
nomenclature,
compounding,
dispensing,
distribution,
administration, education,
monitoring, or use.
All AEs associated with overdose, misuse, abuse, or medication error should be captured on 
the Adverse Event CRF and also reported using the procedures detailed in Section 9.5.4.1
even if the AEs do not meet serious criteria.  Abuse is always to be captured as an AE.  If the 
AE associated with an overdose, misuse, abuse, or medication error does not meet serious

be noted as nonserious on the SAE form and the Adverse Event CRF.
9.5.4.3.2
REPORTING OF STUDY-SPECIFIC EVENTS
Study-specific events (listed below) should always be considered as serious important 
medical events and be entered on the Adverse Event CRF and reported using the procedures 
detailed in Reporting of Serious Adverse Events (Section 9.5.4.1), even if the study-specific 
event does not meet other serious criteria.  


procedures detailed in Reporting of SAEs (Section 9.5.4.1), even if the study-specific 
event does not meet serious criteria.  If the event meets seriousness criteria, it should be 
reported as an SAE as above.  However, if the event listed below does not meet serious 
criteria, it should be noted as nonserious on the Adverse Event CRF:  

Suicidal ideation

Euphoria 
9.5.4.4
Expedited Reporting
The sponsor must inform investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (ie, within 
specific time frames).  For this reason, it is imperative that sites provide complete SAE 
information in the manner described above.
9.5.4.5
Breaking the Blind
In the case of a medical emergency where the appropriate treatment of the subject requires 
knowledge of the study treatment given, the investigator may break the randomization code 
for an individual subject.  In all such cases, the AE necessitating the emergency blind break 
will be handled as an SAE in accordance with the procedures indicated above.  Any broken

code will be clearly justified and documented.  The medical monitor must be notified 
immediately of the blind break.
9.5.4.6
Regulatory Reporting of Adverse Events
Adverse events will be reported by the sponsor or a third party acting on behalf of the 
sponsor to regulatory authorities in compliance with local and regional law and established 
guidance.  The format of these reports will be dictated by the local and regional 
requirements.
9.5.5
Completion/Discontinuation of Subjects
The investigator may withdraw the subject from the study at any time for safety or 
administrative reasons.  A subject may elect to discontinue the study at any time for any 
reason.  All subjects will continue in the study until the 52-week evaluation is completed.  
Subjects who discontinue treatment prematurely will be followed up until study completion.  
All subjects who discontinue the study are to complete the study’s early discontinuation 
procedures indicated in the Schedule of Procedures/Assessments Table 2).
The investigator will promptly explain to the subject involved that the study will be 
discontinued for that subject and provide appropriate medical treatment and other necessary 
measures for the subject.  A subject who has ceased to return for visits will be followed up by 
mail, phone, or other means to gather information such as the reason for failure to return, the 
status of treatment compliance, the presence or absence of AEs, and clinical courses of signs 
and symptoms.
Subjects who discontinue early from the study will be discontinued for 1 of these primary 
reasons: AE(s), lost to follow-up, subject choice, withdrawal of consent, pregnancy, study 
terminated by sponsor, or other.  In addition to the primary reason, the subject may indicate
1 or more of secondary reasons for discontinuation.  Study disposition information will be 
collected on the Subject Disposition CRF.
Detailed retention strategies will be developed and included in study manual. These include 
a highly trained and competent staff, easy access to the clinic, reminder and follow-up calls, 
interactive group sessions with games and hands-on nutrition and physical activity 
demonstrations, random raffle drawings, social events, birthday and holiday cards, and
newsletters. In addition, home visits for assessments of families will be an option, as needed, 
to maximize data collection. This detailed retention plan will help prevent missing data.
A subject removed from the study for any reason may not be replaced.
9.5.6
Abuse or Diversion of Study Drug
During the study, the investigator will report any concern about abuse or diversion of study 
drugs by completing the Abuse or Diversion of Study Drug CRF.  The DEA Registrant has 
the responsibility to comply with local, state, and Federal laws to notify the Field Division 
Office of the DEA of any theft or significant loss of any controlled substances upon 
discovery of such theft or loss.

9.5.7
Confirmation of Medical Care by Another Physician
The investigator will instruct subjects to inform site personnel when they are planning to 
receive medical care by another physician.  At each visit, the investigator will ask the subject 
whether he or she has received medical care by another physician since the last visit or is 
planning to do so in the future.  When the subject is going to receive medical care by another 
physician, the investigator, with the consent of the subject, will inform the other physician 
that the subject is participating in the clinical study.
9.6
Data Quality Assurance
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines.  Site audits 
will be made periodically by the sponsor’s or the CRO’s qualified compliance auditing team, 
which is an independent function from the study team responsible for conduct of the study.
9.6.1
Data Collection
Data required by the protocol will be collected on the CRFs and entered into a validated data 
management system that is compliant with all regulatory requirements.  As defined by ICH 
guidelines, the CRF is a printed, optical, or electronic document designed to record all of the 
protocol-required information to be reported to the sponsor on each study subject.
Data collection on the CRF must follow the instructions described in the CRF Completion 
Guidelines.  The investigator has ultimate responsibility for the collection and reporting of all 
clinical data entered on the CRF.  The investigator or designee as identified on Form 
FDA 1572 must sign the completed CRF to attest to its accuracy, authenticity, and 
completeness.
Completed, original CRFs are the sole property of Eisai and should not be made available in 
any form to third parties without written permission from Eisai, except for authorized 
representatives of Eisai or appropriate regulatory authorities.
9.6.2
Clinical Data Management
All software applications used in the collection of data will be properly validated following 
standard computer system validation that is compliant with all regulatory requirements.  All 
data, both CRF and external data (eg, laboratory data), will be entered into a clinical system.
9.7
Statistical Methods
All statistical analyses will be performed by the sponsor or designee after the study is 
completed and the database is locked and released for unblinding.  Statistical analyses will be 
performed using WinNonlin and SAS software or other validated statistical software as 
required.  Details of the statistical analyses will be included in a separate statistical analysis 
plan (SAP).

Demographic and other baseline characteristics for the FAS and Safety Analysis Sets will be 
summarized for each treatment group using descriptive statistics or frequency count.  
Continuous demographic and baseline variables include age, height, BMI, waist 
circumference, and weight; categorical variables include sex and race.
9.7.1.5

medications will be defined as medications that started on or after the date of the dosing of 
study drug and continued up to 30 days afterward.
9.7.1.6
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, while the PP will 
be used as a supportive analysis.  Unless specified otherwise, a 2-sided α=0.05 significance 
level will be used for all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change 
from baseline in BMI will be analyzed using analysis of covariance model (ANCOVA) with 
factors of treatment, sex (male and female) as fixed effect, and the baseline age and BMI as 
covariates.  The missing values will be imputed using a pattern mixture model utilizing 
multiple imputation (MI) assuming the missing values are missing not at random (MNAR).  
The missing values will be imputed at each visit using all available values including the 
retrieved measurement from the postdiscontinuation data.  The details of the analysis model 
and missing value imputation method will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis: The same primary efficacy analyses described above will be repeated based 
on the PP.

Change from baseline in standardized BMI score (Z-score): The same primary efficacy 
analyses described above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed 
and will be described in the SAP.

Key Secondary Efficacy Analysis
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 
5% BMI reduction at Week 52.  The secondary efficacy endpoint will be analyzed only if the 
test for the primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be 
analyzed using a logistic regression model with factors of treatment, and sex (male and 
female), and baseline BMI as a covariate using FAS.  Subjects with any missing assessment 
at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be 
analyzed using mixed effect model repeated measurement analysis (MMRM) and categorical
variables will be analyzed using the Cochran Mantel Haenszel test, Chi-square test, or 
logistic regression as appropriate.  Additional analysis may be performed as needed using 
appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male 
and female), race (white, black, Asian, and other). Additional subgroups may be explored, if 
deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and 
sensitivity analyses.
9.7.1.7
Pharmacokinetic, Pharmacodynamic, Pharmacogenomic, and Other Biomarker
Analyses
9.7.1.7.1
PHARMACOKINETIC ANALYSES
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling.  The effect of covariates, such as baseline characteristics
or demographics, on PK will be explored.  Derived exposure parameters such as the 
maximum observed concentration and the area under the concentration-time curve from time
0 to 24 hours at steady-state will be calculated from the final PK model using individual 
posterior estimates of the PK parameters and from dosing history.  The PK analysis set will 
be used for this analysis.
9.7.1.7.2
PHARMACODYNAMIC ANALYSES
Change from Baseline in BMI will be assessed as the PD endpoint.  The PD analysis set will 
be used for this analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% 
and ≥10% BMI reduction, and change in waist circumference from baseline) will also be 
assessed as part of the PD analysis.  The PK/PD analysis set will be used for this analysis.

9.7.1.7.3
PHARMACOKINETIC/PHARMACODYNAMIC ANALYSES
Population PK/PD modeling will be used to explore the relationship between lorcaserin 
plasma exposure and response, including but not limited to change in BMI from baseline and 
the probability of achieving at least a 5% and at least a 10% change in BMI from baseline to 
Week 52.  Additionally, exposure-safety relationships for select safety parameters may be 
explored graphically, depending on the data at the end of study.  Any emergent relationship 
may be modeled as appropriate.  Any parameters based on the study data may be considered 
for exploratory assessment for its relationship to PK.

neuromuscular 
sign 
assessment, 
and 
signs 
and 
symptoms 
of 
priapism 
and 
hyperprolactinemia), out-of-normal-range laboratory safety test values, change from baseline 
in laboratory safety test values, ECGs, and vital sign measurements will be summarized by 
treatment group using descriptive statistics or frequency count as appropriate.  (revised per 
Amendment 01)
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
9.7.1.8.1
EXTENT OF EXPOSURE
Subjects will receive Belviq XR 20 mg or placebo QD for up to 52 weeks. The extent of 
exposure will be characterized by duration of exposure (in weeks) for each treatment group.
Duration of exposure will be defined as the number of weeks between the date the subject 
received the 1st dose of study drug and the date the subject received the last dose of study 
drug.  Duration of exposure will be summarized using descriptive statistics by treatment 
group.  In addition, the duration of exposure will be categorized and will be summarized 
using frequency count by treatment group.
9.7.1.8.2
ADVERSE EVENTS
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities 
(MedDRA).  Adverse events will be coded to the MedDRA (Version 18.0 or higher) lower 
level term closest to the verbatim term.  The linked MedDRA PT and primary system organ 
class (SOC) are also captured in the database.

A treatment-emergent AE (TEAE) is defined as an AE that emerges during treatment (up to 
28 days after the last dose of study drug), having been absent at pretreatment (Baseline) or 
•
Reemerges during treatment (up to 28 days after the last dose of study drug), having been 
present at pretreatment (Baseline) but stopped before treatment, or 
•
Worsens in severity during treatment relative to the pretreatment state, when the AE is 
continuous.
Only those AEs that were treatment emergent will be included in summary tables.  All AEs, 
treatment emergent or otherwise, will be presented in subject data listings.
The TEAEs will be summarized by treatment group.  The following summaries will be 
reported for TEAES:

Incidence of TEAEs in descending order of frequency

Incidence of TEAEs by SOC and PT

Incidence of treatment-related TEAEs by SOC and PT

Incidence of TEAEs by SOC, PT and maximum severity (mild, moderate, or severe)

Incidence of treatment-related TEAEs by SOC, PT, and maximum severity (mild, 
moderate, or severe)

Incidence of TEAEs by SOC, PT, and relationship to study drug (Yes [related] or No [not 
related]) 
A subject will be counted only once within a SOC or PT, if the subject experienced more 
than 1 TEAE within a specified SOC and PT.
The following summaries will also be presented for the treatment-emergent SAEs.

Incidence of TEAEs leading to death

Incidence of treatment-emergent SAE by SOC and PT

Incidence of treatment-related treatment-emergent SAE by SOC and PT
In addition, subjects with TEAEs leading to discontinuation from study drug and AEs of 
special interest as described in Section 9.5.4.3.2 will be summarized by MedDRA SOC and 
PT for each treatment group.

baseline to each postbaseline visit and to the end of treatment (defined as the last 
on-treatment value) will be summarized by visit and treatment group using descriptive 
statistics.  Percentages will be based on the number of subjects with both nonmissing 
baseline and relevant postbaseline results.
Laboratory test results will be assigned a low/normal/high (LNH) classification according to 
whether the value was below (L), within (N), or above (H) the laboratory parameter’s 
reference range.  Within-treatment comparisons for each laboratory parameter will be based 
on 3-by-3 tables (shift tables) that compare the baseline LNH classification to the LNH 
classification at the End of Treatment and the Follow-Up visits.  Similar shift tables will also 
compare the baseline LNH classification to the LNH classification for the highest and lowest 
value during the treatment period.
Appendix 1
presents the criteria that will be used to identify subjects with 
treatment-emergent markedly abnormal laboratory values (TEMAV).  Except for phosphate, 
a TEMAV is defined as a postbaseline value with an increase from baseline to a grade of 2 or 
higher.  For phosphate, a TEMAV was defined as a postbaseline value with an increase from 
baseline to a grade of 3 or higher.  When displaying the incidence of TEMAVs, each subject 
may be counted once in the laboratory parameter high and in the laboratory parameter low 
categories, as applicable.
9.7.1.8.4
VITAL SIGNS
Descriptive statistics for vital signs parameters (eg, systolic and diastolic BP, pulse, 
respiratory rate, temperature, weight) and changes from baseline will be presented by visit
and treatment group.
9.7.1.8.5
ELECTROCARDIOGRAMS
For each ECG parameter (including PR interval, RR interval, QRS interval, QT interval, QTc
interval (Bazett formula), QTc interval (Fridericia formula), and heart rate), the actual value 
and change from baseline will be summarized by visit and treatment group using descriptive 
statistics. 
Shift tables will present changes from baseline in ECG interpretation (categorized as normal; 
abnormal, not clinically significant; and abnormal, clinically significant) to end of treatment. 
Maximum postbaseline QTc (Bazett) and QTc (Fridericia) will also be tabulated by treatment 
group as follows:

Number (percentage) of subjects in greater than 450 msec, greater than 480 msec, and 
greater than 500 msec during the treatment, and

Number (percentage) of subjects with an increment of greater than 30 msec and greater 
than 60 msec from the baseline visit.

Other safety assessments including adolescent growth evaluations using 95th percentile CDC 
growth charts and bone age using x-ray of the hand, sexual maturation as measured in Tanner 
Staging, study drug effect on cognition assessed by Leiter-3, assessment of suicidality using 
C-SSRS, and depression assessment using PHQ-9 will be summarized by treatment group at 
each scheduled visit.  For echocardiographic assessments, the proportion of subjects who 
develop FDA-defined valvulopathy, the proportion of subjects who develop pulmonary 
hypertension (defined as when a subject’s SPAP is
≥40 mmHg evaluated by 
echocardiograph], and change from baseline in SPAP will also be summarized by treatment 
group at Week 28 and Week 52. (revised per Amendment 01)
9.7.2
Determination of Sample Size
The proposed sample size is based on the comparison of the primary efficacy endpoint, 
change from Baseline in BMI at Week 52 between the Belviq XR 20-mg treatment group and 
placebo group.  Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of
360 subjects in a 1:1 ratio (n=180 in the Belviq XR 20-mg treatment group; n=180 in the 
placebo group) will have at least 90% power to detect a treatment difference of 1 kg/m2 in 
BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at 
least a 5% BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, 
this sample of 360 subjects (180 subjects for Belviq XR 20 mg and 180 subjects for placebo) 
will also have greater than 85% power to detect an absolute difference of 20% between the 
Belviq XR 20-mg group and placebo group, using a 2-sided Fisher’s Exact test with α=0.05.  
The assumption used in the sample size calculation is based on the 2 pivotal lorcaserin 
studies, APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

Interim Analysis
No interim analysis is planned for this study.

Procedure for Revising the Statistical Analysis Plan
If the SAP needs to be revised after the study starts, the sponsor will determine how the 
revision impacts the study and how the revision should be implemented.  The details of the 
revision will be documented and described in the clinical study report.

11 PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE 
PROCEDURES)
11.1
Changes to the Protocol
Any change to the protocol requires a written protocol amendment or administrative change 
that must be approved by the sponsor before implementation.  Amendments specifically 
affecting the safety of subjects, the scope of the investigation, or the scientific quality of the 
study require submission to health or regulatory authorities as well as additional approval by 
the applicable IRBs/IECs.  These requirements should in no way prevent any immediate 
action from being taken by the investigator, or by the sponsor, in the interest of preserving 
the safety of all subjects included in the study.  If the investigator determines that an 
immediate change to or deviation from the protocol is necessary for safety reasons to 
eliminate an immediate hazard to the subjects, the sponsor’s medical monitor and the 
IRB/IEC for the site must be notified immediately.  The sponsor must notify the health or 
regulatory authority as required per local regulations.
Protocol amendments that affect only administrative aspects of the study may not require 
submission to health or regulatory authority or the IRB/IEC, but the health or regulatory 
authority and IRB/IEC should be kept informed of such changes as required by local 
regulations.  In these cases, the sponsor may be required to send a letter to the IRB/IEC and 
the Competent Authorities detailing such changes.
11.2
Adherence to the Protocol
The investigator will conduct the study in strict accordance with the protocol (refer to ICH 
E6, Section 4.5).
11.3
Monitoring Procedures
The sponsor’s/CRO’s CRA will maintain contact with the investigator and designated staff 
by telephone, letter, or email between study visits.  Monitoring visits to each site will be 
conducted by the assigned CRA as described in the monitoring plan.  The investigator will 
allow the CRA to inspect the clinical, laboratory, and pharmacy facilities to assure 
compliance with GCP and local regulatory requirements.  The CRFs and subject’s 
corresponding original medical records (source documents) are to be fully available for 
review by the sponsor’s representatives at regular intervals.  These reviews verify adherence 
to study protocol and data accuracy in accordance with local regulations.  All records at the 
site are subject to inspection by the local auditing agency and IRB/IEC review.

In accordance with ICH E6, Section 1.52, source documents include, but are not limited to 
the following:
•
Clinic, office, or hospital charts
•
Copies or transcribed health care provider notes which have been certified for accuracy 
after production
•
Recorded data from automated instruments such as IxRS, x-rays, and other imaging 
reports, (eg, sonograms, computerized tomography scans, magnetic resonance images, 
radioactive images, ECGs, rhythm strips, EEGs, polysomnographs, pulmonary function 
tests) regardless of how these images are stored, including microfiche and photographic 
negatives
•
Pain, quality of life, or medical history questionnaires completed by subjects
•
Records of telephone contacts
•
Diaries or evaluation checklists
•
Drug distribution and accountability logs maintained in pharmacies or by research 
personnel
•
Laboratory results and other laboratory test outputs (eg, urine pregnancy test result 
documentation and urine dip-sticks)
•
Correspondence regarding a study subject’s treatment between physicians or memoranda 
sent to the IRBs/IECs
•
CRF components (eg, questionnaires) that are completed directly by subjects and serve as 
their own source
11.4
Recording of Data
A CRF is required and must be completed for each subject by qualified and authorized 
personnel.  All data on the CRF must reflect the corresponding source document, except 
when a section of the CRF itself is used as source document.  Any correction to entries made 
on the CRF must be documented in a valid audit trail where the correction is dated, the 
individual making the correct is identified, the reason for the change is stated, and the 
original data are not obscured.  Only data required by the protocol for the purposes of the 
study should be collected.
The investigator must sign each CRF.  The investigator will report the CRFs to the sponsor 
and retain a copy of the CRFs.
11.5
Identification of Source Data
All data to be recorded on the CRF must reflect the corresponding source documents.

11.6
Retention of Records
The circumstances of completion or termination of the study notwithstanding, the 
investigator is responsible for retaining all study documents, including but not limited to the 
protocol, copies of CRFs, the Investigator's Brochure, and regulatory agency registration 
documents (eg, Form FDA 1572 ICFs, and IRB/IEC correspondence).  In addition, the 
sponsor will send a list of treatment codes by study subject to the investigator after the 
clinical database for this study has been locked.  The site should plan to retain study 
documents, as directed by the sponsor, for at least 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region or at least 3 years have elapsed since the formal 
discontinuation of clinical development of the investigational product.
It is requested that at the completion of the required retention period, or should the 
investigator retire or relocate, the investigator contact the sponsor, allowing the sponsor the 
option of permanently retaining the study records.
11.7
Auditing Procedures and Inspection
In addition to the routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of ICH GCP and all applicable local 
regulations.  If a government regulatory authority requests an inspection during the study or 
after its completion, the investigator must inform the sponsor immediately.
11.8
Handling of Study Drug
All study drugs will be supplied to the PI (or a designated pharmacist) by the sponsor.  Drug 
supplies must be kept in an appropriate secure area (eg, locked cabinet) and stored according 
to the conditions specified on the drug labels.  Investigational product will be stored in 
accordance with the DEA Regulations for Scheduled III - V Drugs and labeled storage 
conditions.  The investigator (or a designated pharmacist) must maintain an accurate record 
of the shipment and dispensing of the study drug in a drug accountability ledger, a copy of 
which must be given to the sponsor at the end of the study.  An accurate record of the date 
and amount of study drug dispensed to each subject must be available for inspection at any 
time.  The CRA will visit the site and review these documents along with all other study 
conduct documents at appropriate intervals once study drug has been received by the site.
All drug supplies are to be used only for this study and not for any other purpose.  The 
investigator (or site personnel) must not destroy any drug labels or any partly used or unused 
drug supply before approval to do so by the sponsor.  At the conclusion of the study and as 
appropriate during the study, the investigator (or a designated pharmacist) will return all used 
and unused drug containers, drug labels, and a copy of the completed drug disposition form 
to the sponsor’s CRA.

Family-Based Lifestyle Program
Program Overview
All subjects and their caregivers (participating parent or guardian) in Study 403 will be 
encouraged to participate in a standardized weight management program for adolescents 
consisting of multicomponent behavior therapy.  The therapy will focus on healthy eating, 
physical activity, and lifestyle changes that will facilitate weight loss and weight-loss 
maintenance. The role of the caregivers is to support their child or adolescents’ lifestyle 
changes and their taking of study medication.
The objectives of this program are as follows:

Develop a weight management program for all Belviq XR study participants and their 
caregivers (caregivers are instructed in methods to support their adolescents’ progress but 
caregivers are themselves not instructed to lose weight or take medication)

Standardize the weight management program across all study sites

Maximize participant retention

Promote participant’s adherence to both taking study medication and following the 
lifestyle program

that patients with body weight 
greater than or equal to 60 kg 
can be administered a dose

population PK/ PD modeling
Study Design
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in obese
adolescents, ages 12 to 17 years.  Approximately 360 subjects will be randomized in a 1:1 ratio to 
Belviq XR 20 mg QD (180 subjects) and placebo (180 subjects).  Subjects will be stratified by sex.  
Subjects will receive Belviq XR 20 mg or placebo QD in a 1:1 ratio for up to 52 weeks. Throughout 
the duration of the study, subjects will be encouraged to adhere to a lifestyle modification program 
that includes a standardized, age-appropriate diet and exercise counseling.
The study will consist of 2 phases: Prerandomization and Randomization.  The Prerandomization 
Phase will last up to 30 days and consist of 1 visit during which subjects will be screened for 
eligibility.  The Randomization Phase consists of a Treatment Period and a Follow-Up Period.  The 
Treatment Period will last for a maximum of 52 weeks, with visits at Weeks 1, 5, 8, 12, 20, 28, 36,
44, and 52.  The Follow-Up Period will extend from the End of Treatment visit to the End of Study 
visit.
Subjects who screen fail can be re-screened only once after 60 days.  All subjects will continue in the 
study until the 52-week evaluation is completed.  Subjects who discontinue treatment prematurely 
will be followed up until study completion.  
Number of Subjects
Approximately 700 subjects will be screened to provide 360 randomized subjects.
Inclusion Criteria
1.
Healthy male or female adolescents, age 12 to 17 years at Screening, with a BMI that is 
greater than or equal to the United States (US)-weighted mean of the 95th percentile based on

Pharmacokinetic Assessments
Plasma lorcaserin concentrations will be measured at Weeks 12, 28, 36, and 52 for analysis of 
population PK.  All subjects will be instructed to take their study drug in the morning on the day 
before their scheduled clinic visit at Weeks 12, 28, 36, and 52.  No additional doses should be taken 
that day for those subjects who have been taking their doses in the evening.  Dose times must be 
recorded for the last 2 dosing times prior to the clinic visit.
On the day of the Week 12, 28, and 52 clinic visits, subjects will be instructed to take their study drug 
at approximately the same time as the morning before, with no additional doses taken that day.  Two 
blood samples for determination of plasma concentrations of lorcaserin will be taken at each of these 
visits: within 30 minutes before dosing and within 1 to 3 hours after dosing.  
On the day of the Week 36 clinic visit, subjects will take their study drug in the morning at home.  
One blood sample for determination of plasma concentrations of lorcaserin will be collected at the 
clinic within 4 to 6 hours after dosing.
Subjects can resume their usual dose schedule the day after the PK clinic visits.  
Pharmacodynamic Assessments

Change from baseline in BMI 

Proportion (%) of subjects achieving at least a 5% and at least a 10% reduction in BMI
Other PD endpoints will be considered based on the data at the end of the study to explore their 
relationships with lorcaserin plasma exposure.
Pharmacogenomic/Pharmacogenetic Assessments
Not applicable
Safety Assessments
Safety assessments will consist of monitoring and recording all adverse events (AEs) and serious 
adverse events (SAEs); electrocardiograms (ECGs); laboratory evaluation for hematology, metabolic 
function (glucose, fasting lipids, and thyroid), adrenal function and biochemical blood and urine bone 
health assessments; blood chemistry and urine values; neuropsychiatric events; periodic measurement 
of vital signs, neuromuscular signs for screening potential serotonin syndrome, and signs or 
symptoms of priapism and prolactinemia; and performance of physical examinations.
In patients 
with potential prolactin-related AEs, such as galactorrhea, changes in libido, or changes to menstrual 
cycle, prolactin level will be measured and assessed. Study drug effect on growth will be evaluated 
using the CDC growth chart at Baseline, and Weeks 5, 12, 28, 36, 52, and at Follow-Up; a full 
physical examination, at Baseline, Weeks 1, 12, 28, 52, and at Follow-Up; and bone age 
determination by x-ray of the hand at Baseline, Weeks 12, 28, and 52. Sexual maturation will be 
evaluated by assessing sex hormones and self-reported changes in Tanner Staging at Baseline, 
Weeks 28 and 52, and at Follow-Up.   
The C-SSRS will be used to assess all subjects in the study for any signal of depression or suicidal 
ideation or behavior at every visit.  Additionally, screening, diagnosing, monitoring, and measuring 
the severity of depression will be assessed using the PHQ-9 at every visit and effects on cognitive

function will be assessed using the WRAML-2 at Baseline, Weeks 5, 28, 52, and end of study (EOS).
Echocardiographic assessments will be used to exclude subjects with FDA-defined valvulopathy, 
pulmonary hypertension, and other major cardiovascular disease (as outlined in Exclusion Criterion 
No. 3) during the Screening Period.  Additionally, cardiac valvular function and pulmonary systolic 
pressure changes at Weeks 28 and 52 will be assessed.
Valvular regurgitation as assessed in the 
echocardiogram will be rated absent, trace, mild, moderate, or severe for the aortic, mitral, and 
tricuspid valves; the rating will be absent or present for the pulmonic valve. The evaluations will be 
based on guidelines from the American Society of Echocardiography. Pulmonary artery pressure will 
be estimated from the TR jet velocity.
Bioanalytical Methods
Lorcaserin will be quantified in plasma using a validated liquid chromatography method coupled with 
tandem mass spectrometry.


The Full Analysis Set (FAS) is the group of all randomized subjects regardless of adherence to 
study drug.

Per-Protocol Analysis Set (PP) is the group of all randomized subjects who are 80% or greater 
compliant with study medication, completed the study, have no major protocol deviations, have 
no violations of inclusion or exclusion criteria, and have BMI data at Baseline and Week 52.  
The determination of subjects to be excluded from this population based on the above criteria 
and a list of major protocol violations will be included in the statistical analysis plan (SAP) and 
finalized before data base lock.

The PD Analysis Set is the group of subjects who had sufficient PD data to derive at least 1 PD 
parameter.

The PK Analysis Set is the group of all randomized subjects from whom at least 1 valid 
lorcaserin plasma concentration was obtained with associated documented dosing history.

The population PK/PD set is the group of randomized subjects with PK information and who 
have at least 1 adequately documented measurement of BMI.
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, and the PP will be used as 
a supportive analysis.  Unless otherwise specified, a 2-sided α=0.05 significance level will be used in 
all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change from 
baseline in BMI will be analyzed using analysis of covariance model (ANCOVA) with factors of 
treatment,  sex (male and female) as fixed effect, and the baseline age and BMI as covariates.  The 
missing values will be imputed using a pattern mixture model utilizing multiple imputation (MI) 
assuming the missing values are missing not at random (MNAR).  The missing values will be 
imputed at each visit using all available values including the retrieved measurement from the 
postdiscontinuation data.  The details of the analysis model and missing value imputation method 
will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis:  The same primary efficacy analyses described above will be repeated based on 
the PP.

Change from baseline in standardized BMI score (Z-score):  The same primary efficacy 
analyses described above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed and will 
be described in the SAP.
Key Secondary Efficacy Analyses
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 5% BMI 
reduction at Week 52. The secondary efficacy endpoint will be analyzed only if the test for the 
primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be analyzed using

a logistic regression model with factors of treatment, sex (male and female), and baseline BMI as a 
covariate using FAS.  Subjects with any missing assessment at Week 52 will be considered as 
treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be analyzed 
using mixed effect model repeated measurement analysis (MMRM) and categorical variables will be 
analyzed using the Cochran Mantel Haenszel test, Chi-square test, or logistic regression as 
appropriate.  Additional analysis may be performed as needed using appropriate statistical 
methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male and 
female), and race (white, black, Asian, and other).  Additional subgroups may be explored, if deemed 
necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and sensitivity 
analyses.
Pharmacokinetic Analyses
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling. The effect of covariates such as baseline characteristics or 
demographics on PK will be explored. Derived exposure parameters such as the maximum observed 
concentration and the area under the concentration-time curve from time 0 to 24 hours at steady-state 
will be calculated from the final PK model using individual posterior estimates of the PK parameters 
and from dosing history. The PK analysis set will be used for this analysis.
Pharmacodynamic Analyses
Change from Baseline in BMI will be assessed as the PD analysis.  The PD analysis set will be used 
for this analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% and 
≥10% BMI reduction, and change in waist circumference from baseline) will also be assessed as part 
of the PD analysis.  The PK/PD analysis set will be used for this analysis.
Pharmacokinetic/Pharmacodynamic Analyses
Population PK/PD modeling will be used to explore the relationship between lorcaserin plasma 
exposure and response, including but not limited to change in BMI from baseline and the probability 
of achieving at least a 5% and at least a 10% change in BMI from baseline to Week 52.  Additionally, 
exposure-safety relationships for select safety parameters may be explored graphically depending on 
the data at the end of study.  Any emergent relationship may be modeled as appropriate.  Any 
parameters based on the study data may be considered for exploratory assessment for its relationship 
to PK.
Pharmacogenomic/Pharmacogenetic Analyses
Not applicable
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments including the 
incidence of AEs (including changes from baseline in physical examination), growth (CDC growth 
chart and bone age determined by x-ray of the hand), sexual maturation (Tanner Staging),

out-of-normal-range laboratory safety test values, change from baseline in laboratory safety test 
values, ECGs, and vital sign measurements will be summarized by treatment group using descriptive 
statistics or frequency count as appropriate.  In addition, cognitive function will be evaluated by the
WRAML-2, depression will be evaluated by the PHQ-9, and suicidal ideation and behavior will be 
evaluated by the C-SSRS, and will also be summarized by treatment group using descriptive statistics 
or frequency count as appropriate.
All WRAML-2 raw scores from the Core Battery will be 
converted to age and gender standard scores for purposes of intra-individual comparisons. For 
echocardiographic assessments, the proportion of subjects who develop FDA-defined valvulopathy, 
the proportion of subjects who develop pulmonary hypertension [pulmonary hypertension is defined 
when the subject’s systolic pulmonary artery pressure (SPAP) ≥40 mmHg evaluated by 
echocardiograph], and change from baseline in SPAP will be summarized by treatment group at 
Week 28 and Week 52 using descriptive statistics or frequency count as appropriate.
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
Interim Analyses
Not applicable
Sample Size Rationale
The proposed sample size is based on the comparison of the primary efficacy endpoint, change in 
BMI from Baseline to Week 52 between the Belviq XR 20-mg treatment group and placebo group.  
Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 360 subjects in a 1:1 ratio 
(n=180 in the Belviq XR 20-mg treatment group; n=180 in the placebo group) will have at least 
90% power to detect a treatment difference of 1 kg/m2 in BMI, using a 2-sided t-test with α=0.05.  
Assuming the proportion of subjects achieving at least a 5% BMI reduction at Week 52 is 20% for 
the placebo group and a 40% dropout rate, this sample of 360 subjects (180 subjects for Belviq XR 
20 mg and 180 subjects for placebo) will also have greater than 85% power to detect an absolute 
difference of 20% between the Belviq XR 20-mg group and the placebo group, using a 2-sided 
Fisher’s Exact test with α=0.05. The assumption used in the sample size calculation is based on the 
2 pivotal lorcaserin studies APD356-009 and APD356-011 in obese and overweight non-diabetic 
adult subjects.

ETHICS
5.1
Institutional Review Boards/Independent Ethics Committees
The protocol, Informed Consent Form (ICF), and appropriate related documents must be 
reviewed and approved by an Institutional Review Board (IRB) or Independent Ethics 
Committee (IEC) constituted and functioning in accordance with International Conference on 
Harmonisation (ICH) Good Clinical Practice (ICH E6), Section 3, and any local regulations 
(eg, Federal Regulations, Title 21 Code of Federal Regulations [21 CFR] Part 56).  Any 
protocol amendment or revision to the ICF will be resubmitted to the IRB/IEC for review and 
approval, except for changes involving only logistical or administrative aspects of the study 
(eg, change in clinical research associate [CRA], change of telephone number[s]).  
Documentation of IRB/IEC compliance with the ICH E6 and any local regulations regarding 
constitution and review conduct will be provided to the sponsor.
A signed letter of study approval from the IRB/IEC chairman must be sent to the principal 
investigator (PI) with a copy to the sponsor before study start and the release of any study 
drug to the site by the sponsor or its designee (ICH E6, Section 4.4).  If the IRB/IEC decides 
to suspend or terminate the study, the investigator will immediately send the notice of study 
suspension or termination by the IRB/IEC to the sponsor.
Study progress is to be reported to IRB/IECs annually (or as required) by the investigator or 
sponsor, depending on local regulatory obligations.  If the investigator is required to report to 
the IRB/IEC, he/she will forward a copy to the sponsor at the time of each periodic report.  
The investigator(s) or the sponsor will submit, depending on local regulations, periodic 
reports and inform the IRB/IEC of any reportable adverse events (AEs) per ICH guidelines 
and local IRB/IEC standards of practice.  Upon completion of the study, the investigator will 
provide the IRB/IEC with a brief report of the outcome of the study, if required.

INTRODUCTION
7.1
Indication
Obesity
Obesity has become a global epidemic in western civilization, causing a serious public health 
concern.  In the United States, the prevalence of obesity in adolescents ages 12 and 19 years
has almost doubled over the past 2 decades.  The rate increased from 10.5% between 1988 
and 1994 to 20.5% between 2011 and 2012 (CDC/NCHS, 2013).  Obesity in adolescents, 
defined in the United States as greater than or equal to the 95th percentile in gender- and 
age-specific body mass index (BMI), continues to grow at an alarming rate in the United 
States and globally.  Based on data (Wang and Lobstein, 2006) using various criteria for the 
definition of obesity that included more than 30 countries in Europe, North America, Asia, 
and the West Pacific, prevalence of obesity in these countries has also increased 
significantly, at a rate comparable to that in the United States.
Adolescent obesity has many negative implications for both the health and well-being of the 
individual as well as for society.  These include increased susceptibility to a host of diseases, 
chronic health disorders, psychological disorders, and premature death (Flegal, et al., 2005; 
Rofey, et al., 2009).  Increases in the prevalence of overweight and obese adolescents may 
result in a decrease in life expectancy for the 1st time in 200 years (Peeters, et al., 2003).
As a result, there is a significant impact on the cost of healthcare.  It is estimated that medical 
costs due to overweight adolescents are approximately $14 billion per year in the United 
States (Trasande and Chatterjee, 2009).  Obesity-related medical costs in general are
expected to rise significantly because today’s obese adolescents are likely to become 
tomorrow’s obese adults (Whitaker, et al., 1997).
Current approaches to weight management in adults include lifestyle modification, 
pharmacotherapy, and invasive bariatric procedures.  Lifestyle modification involves a 
combination of diet, exercise, and behavioral change, and is the preferred and essential 
strategy for weight management in obese and overweight individuals, including adolescents.  
Although lifestyle modification can be very efficacious in some patients, adherence to the 
prescribed regimens is often poor.  As such, lifestyle modification alone is often not adequate 
and the weight loss is often transient.  On the other hand, bariatric surgery and various other 
invasive procedures are generally reserved for the severely obese population. 
Pharmacotherapy can play a significant role in weight management programs, and is often 
combined with lifestyle modification to enhance weight loss beyond that which is normally 
achieved with diet and exercise alone.  Current pharmacotherapies offer the potential to 
significantly augment weight loss when combined with diet and exercise, but are rarely used 
for adolescents.
The current standard of care for treatment of obesity in adolescent subjects ranges from
behavioral therapy including lifestyle intervention to the rare use of pharmacotherapy in

adolescents over 12 years of age (McGovern, et al, 2008; Spear, et al, 2007).  Xenical®
(orlistat) is currently the only product available for weight control in obese adolescent 
patients 12 to 16 years of age.  However, it is associated with gastrointestinal side effects 
(Xenical PI. 2015), and the treatment effect of Xenical is modest. In a study that included 
539 obese adolescents with BMI above the 97th percentile, Xenical demonstrated a 0.86 BMI 
reduction relative to placebo after 52 weeks of treatment (-0.55 BMI in the Xenical treatment 
group versus +0.31 BMI in the placebo group) (FDA, 2003; Chanoine, et al, 2005).
Obtaining maximum retention in the study is a major goal in order to minimize missing data.  
A number of strategies have been used in prior adolescent weight loss studies that will be 
used in the present study to help retain participants.  These include a highly trained and 
competent staff, ample waiting area, readily available parking (at no cost), access to mass 
transit, and reminder and follow-up calls.  In addition, we will provide fun and interactive 
group sessions with games and hands-on nutrition and physical activity demonstrations, 
random raffle drawings, social events, birthday and holiday cards, and newsletters.  
Furthermore, we will make home visits for assessments of families, as needed, to maximize 
data collection. 
By using these retention strategies, we hope that we will maximize 
participant retention, which will help us cope with missing data.
7.1.1
APD356/Belviq (lorcaserin hydrochloride)
7.1.1.1
Mechanism of Action
Belviq is a selective serotonin 2c receptor agonist which was approved by the US Food and 
Drug Administration (FDA) on 27 Jun 2012 as an adjunct to a reduced-calorie diet and 
increased physical activity for chronic weight management in adult patients with a BMI of at 
least 30 kg/m2 (obese), or adult patients with a BMI greater than or equal to 27 kg/m2
(overweight) in the presence of at least 1 weight-related comorbid condition.
7.1.1.2
Clinical Experience with APD356/Belviq (lorcaserin hydrochloride)
The Phase 3 clinical evaluation of Belviq in studies of more than 7700 adult subjects, 
including 604 subjects with Type 2 diabetes mellitus, demonstrated clinically meaningful 
efficacy and a safety profile that includes minimal and easily managed risks.  In each of the 
individual studies and in the pooled efficacy analyses, the Belviq dose met the following 
prespecified endpoints:

A significantly greater proportion of adult subjects taking Belviq 10 mg twice per day 
(BID) (47%) lost at least 5% of baseline body weight at 52 weeks as compared to 
subjects taking placebo (23%).  A significantly greater proportion of subjects taking 
Belviq 10 mg BID (22.4%) lost at least 10% of baseline body weight at 1 year as 
compared to subjects taking placebo (8.7%). 

The mean weight loss at 1 year in adult subjects taking Belviq 10 mg BID (-5.8 kg) 
was significantly greater than that in subjects taking placebo (-2.5 kg).
An integrated evaluation of the data from the pediatric, adolescent, and adult subjects 
revealed that the relationship between lorcaserin area under the curve (AUC) and body

weight in pediatric and adult subjects is consistent irrespective of the individual studies or 
age range of the study population. Irrespective of age, lorcaserin AUC values in the pediatric 
subjects with body weight of greater than 60 kg overlapped with the data observed from the 
studies involving adult subjects, suggesting a fixed dose approach similar to adults can be 
used for adolescent subjects with body weight greater than 60 kg.
In adolescent obese populations, it is anticipated that Belviq XR will result in similar effects.
As part of FDA postmarketing requirements, this study is designed to characterize the 
efficacy and safety of Belviq XR in adolescent obese populations in the United States.  It is 
also intended to support an indication for chronic weight management for obese adolescents 
ages 12 to 17 years old. 
7.1.2
Study Rationale
There is no specific FDA guidance for the approval of a weight loss product for adolescents.  
In adults, the Division’s 2007 draft Guidance for Industry Developing Products for Weight 
Management indicate that the product needs to satisfy either of the following mean or 
categorical criteria after 1 year of treatment:

The difference in mean weight loss between the active-product and placebo-treated 
groups is at least 5% and the difference is statistically significant.

The proportion of subjects who lose at least 5% of baseline body weight in the 
active-product group is at least 35%, is approximately double the proportion of 
subjects in the placebo-treated group who lose at least 5% of baseline body weight, 
and the difference between groups is statistically significant.
FDA awarded a weight management indication for Belviq based on Phase 3 study results 
which achieved the categorical criteria. In a Phase 3 study, a significantly greater proportion 
of subjects taking Belviq (47%) lost at least 5% of baseline body weight at 1 year as 
compared to subjects taking a placebo (23%).  It is anticipated that a similar effect will be 
demonstrated in obese adolescents, where weight loss will be assessed using BMI
measurements to account for growth. In this study, the objective is to demonstrate that BMI
reduction will be achieved during 52 weeks of treatment with Belviq XR 20 mg administered 
once daily (QD) compared to placebo in obese adolescents.
In the Phase 3 orlistat study in obese adolescents mentioned above, the proportion of subjects 
who lost at least 5% body weight is relatively low. At the end of the study at Week 52, only 
26.5% of the subjects achieved a 5% or greater BMI reduction compared to 15.7% in the 
placebo group. The placebo-corrected BMI reduction was about 0.86 kg/m2.  
There are limited trials for weight reduction in the adolescent population, ages 12 to 17 years
(Peirson, et al, 2015).  Thirty-one studies (29 behavioral, 2 pharmacological and behavioral) 
were included in a meta-analysis of randomized studies conducted in primary care centers in 
overweight and obese children and youth ages 2 to 18 years using behavioral (diet, exercise,
and lifestyle) and pharmacological interventions and providing 6-month postbaseline BMI or 
prevalence of overweight or obesity. Both interventions showed a significant effect on BMI

in favor of treatment (behavioral: 
standardized mean difference [SMD] -0.54, 
95% confidence interval [CI]
-0.73, -0.36; orlistat plus behavioral: 
SMD -0.43, 
95% CI -0.60, -0.25). The studies reported no significant difference between groups in the 
likelihood of reduced prevalence of overweight or overweight and obese. A great deal of 
variation was noted across efficacious interventions.
In conclusion, this meta-analysis 
demonstrated low-quality evidence that behavioral treatments alone are associated with a 
smaller effect in terms of reduced BMI compared with the effect shown by combined 
behavioral and pharmacological interventions. This may be because the effect size in the 
randomized, double blind, placebo controlled, phase 3 orlistat study in adolescents was 
relatively low and there was a lack of maintenance effect. These subjects started to regain 
their BMI after 6 months of treatment. At end of the study, only 26.5% of subjects achieved 
a 5% or greater BMI reduction compared to 15.7% in placebo group. In a sibutramine 
Phase 3 study in obese adolescents, a substantially higher proportion of subjects (69%) 
treated with sibutramine achieved at least a 5% BMI reduction compared to 21% of subjects 
in the placebo group. In addition, sibutramine resulted in a substantial reduction in mean 
BMI (between-group difference, 2.9 kg/m2) and mean weight (between-group difference, 
8.4 kg) compared to placebo (Berkowitz, et al, 2006).  Unlike the weight loss effect of Belviq
in adults and sibutramine in adolescents, subjects in the orlistat study started to increase their 
BMI after 6 months of treatment.
In this study, it is assumed that treatment with Belviq XR 20 mg will lead to a BMI reduction
of more than 1 kg/m2, and a higher proportion of subjects will achieve more than a 5% and 
10% BMI reduction compared to placebo.  A between-group difference of 24% is the basis 
for the conservative assumption of a 20% effect size in the current study.
In addition, the total sample size of 360 subjects will be adequate to assess safety and 
exposure based on previous adolescent studies with weight management products (orlistat 
and sibutramine) (FDA, 2003; Chanoine, et al, 2005; Berkowitz, et al, 2006) and other 
metabolic or dyslipidemia medication products (ezetimibe, simvastatin) (FDA, 2007).

INVESTIGATIONAL PLAN
9.1
Overall Study Design and Plan
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in 
obese adolescents ages 12 to 17 years.  Approximately 360 subjects will be randomized in a 
1:1 ratio to Belviq XR 20 mg QD (180 subjects) and placebo (180 subjects).  Subjects will be 
stratified by sex.  Subjects will receive Belviq XR 20 mg or placebo QD in a 1:1 ratio for up 
to 52 weeks. Throughout the duration of the study, subjects will be encouraged to adhere to 
a lifestyle modification program that includes a standardized, age-appropriate diet and 
exercise counseling (see Appendix 2).  
The study will consist of 2 phases:
Prerandomization and Randomization.  The 
Prerandomization Phase will last up to 30 days and consists of 1 visit during which subjects 
will be screened for eligibility.  The Randomization Phase consists of a Treatment Period and 
a Follow-Up Period.  The Treatment Period will last for a maximum of 52 weeks, with visits 
at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52; the Follow-Up Period will extend from the 
End of Treatment (EOT) visit to the End of Study (EOS) visit.
Subjects who screen fail can be re-screened only once after 60 days.  All subjects will 
continue in the study until the 52-week evaluation is completed.  Subjects who discontinue 
treatment prematurely will be followed up until study completion.
9.1.1
Prerandomization/Pretreatment Phase
Screening will occur during the Prerandomization Phase at Visit 1
9.1.1.1
Screening Period
The purpose of the Screening Period is to obtain the informed consent and assent and to 
establish protocol eligibility.  Procedures to be followed when obtaining informed consent 
are detailed in Section 5.3.  Careful initial screening is important in the recruitment of 
families who both fully understand the requirements of this 1 year, randomized, controlled 
trial and are truly interested in participation.  Interested caregivers and adolescents will be 
screened by phone to assess preliminary entry criteria.  Candidates will be given a brief 
description of the program and general study requirements, with an adolescent and a 
caregiver who is willing to participate.  If preliminary entry criteria are met, adolescents and 
their caregivers will be invited to an initial in-clinic meeting to further discuss the study.  A 
complete description of the study including assessments, the number of visits, the lifestyle 
program, the fact that the adolescent would be taking either the study drug or a placebo, the
duration of the study, and the necessity of having an adolescent wishing to participate as well 
as a participating caregiver will be described.  Consent and assent will be obtained and copies 
of the signed forms will be provided to families.  The importance of the study and its 
scientific merit will be discussed.  Ineligible adolescents will be referred to local weight 
management resources.  Screening period assessments and timing thereof are shown in 
Section 9.5.2.

Discussion of Study Design, Including Choice of Control Groups
The proposed dose and dosing frequency of Belviq XR in this study is 20 mg QD.  The PK 
parameters of a single 10-mg dose of Belviq were evaluated in healthy, adolescent obese 
subjects in Study APD356-025.  Overall, the PK parameters of Belviq and its main 
metabolites, M1 and M5, were similar to those in adults.  Following a single, oral 
administration of Belviq 10 mg to a total of 8 healthy adolescent (ages 12 to 17 years old) 
obese subjects, the mean maximum concentration observed and the area under the 
concentration-time curve from time zero to infinity (AUC(0-inf)) were 36.5 ng/mL and 
464 hr×ng/mL, respectively.  The mean Belviq terminal phase half-life was 9.70 hours, 
similar to that observed in adults, thus supporting a similar dosing frequency (QD) in 
adolescent subjects.
Additionally, a single dose PK study in 8 healthy obese pediatric subjects ages 6 to 11 years 
of age was performed. The PK analysis after a single 10-mg dose of lorcaserin revealed that 
the lorcaserin AUC(0-inf) values tended to increase with decreasing body weight and age.
However, the body weight normalized AUC(0-inf) values were similar across the age groups, 
therefore the data indicated no effect of age on the lorcaserin PK. Integrated assessment of 
the PK versus body weight relationship, pooling the data from pediatric and adult subjects 
from previous studies, suggested that the lorcaserin area under the curve values for subjects 
with body weight of at least 60 kg overlapped with the area under the curve values from 
adolescents and adults. Therefore, no dose adjustment relative to adults and adolescents is 
deemed necessary for pediatric or adolescent subjects with a body weight of at least 60 kg.
Based on CDC growth charts, the likelihood of subjects who are older than 12 years of age 
having a body weight of less than 60 kg is very low; therefore, the current study as designed 
to enroll subjects between 12 to 17 years of age with body weight at least 60 kg, will cover
majority of the population of interest.  The targeted study population comprises 360 obese 
adolescents 12 to 17 years of age, with a body weight at least 60 kg.
Obese adolescents will be identified using gender- and age-specific BMI measurement.  
Obesity in adolescents is defined by US Expert committee recommendations as BMI in or 
above the 95th percentile (Barlow, 2007).

Randomization will be used in this study to avoid bias in the assignment of subjects to 
treatment, to increase the likelihood that known and unknown subject attributes 
(eg, demographics, baseline characteristics) are balanced across treatment groups, and to 
ensure the validity of statistical comparisons across treatment groups.  Blinding to treatment 
will be used to reduce potential bias during data collection and evaluation of endpoints.
9.3
Selection of Study Population
Approximately 700 subjects will be screened to ensure that 360 subjects will be randomized.
Subjects who do not meet all inclusion criteria or do meet any exclusion criteria will not be 
eligible to receive study drug. Subjects who screen fail can be re-screened only once after 
60 days.
9.3.1
Inclusion Criteria
Subjects must meet all of the following criteria to be included in this study:
1. Healthy male or female adolescents, ages 12 to 17 years old at Screening, with a BMI 
that is greater than or equal to the United States (US)-weighted mean of the 
95th percentile based on age and sex with a body weight greater than 60 kg
2. Subjects and their families are not planning to move away from the area for the 
duration of the study
3. Subjects able and willing to comply with all aspects of the study, including a 
standardized, reduced-calorie diet and an age-appropriate, increased physical activity 
program
4. Subjects considered in stable health in the opinion of the investigator
5. Caregivers or guardians meet the following requirements:
a.
Able and willing to support and supervise study participation in the opinion of the 
investigator, including consideration of any existing physical, medical, or mental 
condition that prevents compliance with the protocol
b. Able and willing to personally comply with and execute all aspects of the study 
requirements for the caregivers or guardians
9.3.2
Exclusion Criteria
Subjects who meet any of the following criteria will be excluded from this study:
1. Clinically significant new illness within 1 month before randomization that may 
affect the subject’s ability to fulfill the study requirements or significantly confound 
the assessments
2. Subjects who cannot swallow investigational products
3. Any of the following findings on screening echocardiography:

Aortic regurgitation mild or greater


Mitral regurgitation moderate or greater

Mitral or aortic valve stenosis greater than mild (ie, aortic stenosis [AS]: 
jet >3.0 m/s, mean gradient >25 mm Hg, and aortic valve area [AVA] 
<1.5 cm2; MS: mean gradient >5 mm Hg and mitral valve area [MVA] 
<1.5 cm2)

Systolic pulmonary artery pressure (SPAP) >40 mm Hg (and/or tricuspid 
regurgitation (TR) jet velocity >2.9 m/s)
-
In cases where an actual SPAP value is not measurable due to lack of 
adequate TR jet, the pulmonary flow acceleration time measured at the 
right ventricular outflow tract (RVOTAT), will be used to assess 
eligibility. Patients with a RVOTAT ≤100 msec will be excluded, 
suggesting an elevated mean SPAP; eligibility for the those patients with 
RVOTAT between 100 and 120 msec will be determined based on 
combined assessment of the TR jet, septal motion and right ventricular 
size.

Left ventricular ejection fraction <45%

Intracardiac mass, tumor or thrombus

Evidence of congenital heart disease

Clinically significant pericardial effusion (eg, moderate or larger or with 
hemodynamic compromise)
4. Significant renal or hepatic disease as evidenced by a serum creatinine greater than

thermometric values over a specific time period can be recorded and retrieved as required.
9.4.3
Method of Assigning Subjects to Treatment Groups
Subjects will be assigned to treatments based on a computer-generated randomization 
scheme that will be reviewed and approved by an independent statistician.  The 
randomization scheme and identification for each subject will be included in the final clinical 
study report for this study.
Subjects will be centrally stratified by sex (male and female).  Within each stratum, subjects 
will be randomized to receive either Belviq XR 20 mg or placebo QD in a 1:1 ratio.  
Randomization will be performed centrally by an interactive voice or web response system 
(IxRS).  The IxRS or clinical supply vendor will generate the randomized identification
numbers to be included on study packaging.  Upon signature of the ICF, the investigator or 
designee will access the IxRS to register the subject information.  At Randomization, the 
IxRS will assign each subject a unique randomization number.  At each subsequent visit 
during the Treatment Period and Follow-Up Period, the investigator or designee will access 
IxRS to obtain dispensing information and to register the subject’s visit.
9.4.4
Selection and Timing of Dose for Each Subject
Subjects should take the study medication once daily at approximately the same time of 
every day, and be encouraged to take the study medication with an adequate amount of water 
(8 oz. or 240 mL).
9.4.5
Blinding
During the Randomization Phase, subjects and all personnel involved with the conduct and 
interpretation of the study, including investigators, site personnel, and sponsor staff will be 
blinded to the treatment codes.  Randomization data will be kept strictly confidential, filed 
securely by an appropriate group with the sponsor or CRO, and accessible only to authorized 
persons (eg, Eisai Global Safety) until the time of unblinding, per the SOP.
A master list of all treatments and the subject numbers associated with them will be 
maintained in a sealed envelope by the clinical supply vendor, the IxRS vendor, and the 
sponsor.  In the event that emergency conditions require knowledge of the study treatment 
given, the blind may be broken via the code breaker facility within the IxRS.  Emergency 
procedures for revealing drug codes are given in Section 9.5.4.5.  If possible, before breaking 
the blind, the investigator should consult with the sponsor or designee to ascertain the 
necessity of breaking the code.

Echocardiographic assessments will be used to exclude subjects with FDA-defined 
valvulopathy, pulmonary hypertension, and other major cardiovascular disease (as outlined in 
Exclusion Criterion No. 3) during the Screening Period.  Additionally, cardiac valvular 
function and pulmonary systolic pressure changes at Weeks 28 and 52 will be assessed.  
Valvular regurgitation as assessed in the echocardiogram will be rated absent, trace, mild, 
moderate, or severe for the aortic, mitral, and tricuspid valves; the rating will be absent or 
present for the pulmonic valve. The evaluations will be based on guidelines from the 
American Society of Echocardiography. Pulmonary artery pressure will be estimated from 
the tricuspid regurgitant jet velocity.
9.5.1.5.1
ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered an investigational product.  An AE does not necessarily have a causal 
relationship with the medicinal product.  For this study, the study drug is Belviq XR
(lorcaserin hydrochloride).
The criteria for identifying AEs in this study are:
•
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or 
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE)
•
Any new disease or exacerbation of an existing disease 
•
Any deterioration in non-protocol-required measurements of a laboratory value or other 
clinical test (eg, ECG, x-ray) that results in symptoms, a change in treatment, or 
discontinuation of study drug
•
Recurrence of an intermittent medical condition (eg, headache) not present pretreatment 
(Baseline)
•
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of study drug, or withholding 
of study drug, whether prescribed in the protocol or not.
All AEs observed during the study will be reported on the Adverse Event CRF.  All AEs, 
regardless of relationship to study drug or procedure, should be collected beginning from the 
time the subject signs the study ICF through the last visit in the Treatment Phase.  Subjects 
who fail screening primarily due to AE(s) must have the AE(s) leading to screen failure 
reported on the Screening Disposition CRF.  SAEs will be collected for 28 days after the last 
dose.
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute 
an AE.  Medical and scientific judgment should be exercised in deciding whether an isolated

Clinical Study Protocol
APD356-A001-403
Eisai
FINAL (v5.0):  22 Feb 2017 
Confidential
Page 44 of 81
laboratory abnormality should be classified as an AE.  Any laboratory abnormality 
considered to constitute an AE should be reported on the Adverse Event CRF. 
Abnormal ECG (corrected QT interval [QTc]) results, if not otherwise considered part of a 
clinical symptom that is being reported as an AE, should be considered an AE if the QTc 
interval is greater than 450 msec and there is an increase of more than 60 msec from baseline.  
Any ECG abnormality that the investigator considers as an AE should be reported as such.
It is the responsibility of the investigator to review the results of the C-SSRS, PHQ-9, and 
WRAML-2 in all subjects and determine if any result constitutes an AE.  Medical and 
scientific judgment should be exercised in deciding whether an isolated suicidality rating 
scale response should be classified as an AE (see Section 9.5.1.5.9 for a description of the 
C-SSRS).
All AEs must be followed for 28 days after the subject’s last dose or until resolution, 
whichever comes first.  All SAEs must be followed to resolution or, if resolution is unlikely, 
to stabilization.
Every effort must be made by the investigator to categorize each AE according to its 
severity and its relationship to the study treatment.
Assessing Severity of Adverse Events
Adverse events will be graded on a 3-point scale (mild, moderate, severe) and reported in the 
detail indicated on the CRF.  The definitions are as follows:
Mild
Discomfort noticed, but no disruption of normal daily activity
Moderate Discomfort sufficient to reduce or affect normal daily activity
Severe
Incapacitating, with inability to work or to perform normal daily activity
The criteria for assessing severity are different than those used for seriousness (see
Section 9.5.1.5.2 for the definition of an SAE).
Assessing Relationship to Study Treatment
Items to be considered when assessing the relationship of an AE to the study treatment are:
•
Temporal relationship of the onset of the event to the initiation of the study treatment
•
The course of the event, especially the effect of discontinuation of study treatment or 
reintroduction of study treatment, as applicable
•
Whether the event is known to be associated with the study treatment or with other 
similar treatments
•
The presence of risk factors in the study subject known to increase the occurrence of 
the event

•
The presence of nonstudy, treatment-related factors that are known to be associated 
with the occurrence of the event
Classification of Causality
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question:
Is there a reasonable possibility that the study drug caused the AE?
Yes (related)
A causal relationship between the study drug and the AE is a reasonable 
possibility.
No (not related) A causal relationship between the study drug and the AE is not a 
reasonable possibility.
9.5.1.5.2
SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An SAE is any untoward medical occurrence that at any dose:
•
Results in death
•
Is life-threatening (ie, the subject was at immediate risk of death from the AE as it 
occurred; this does not include an event that, had it occurred in a more severe form or 
was allowed to continue, might have caused death)
•
Requires inpatient hospitalization or prolongation of existing hospitalization
•
Results in persistent or significant disability/incapacity
•
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug)
Other important medical events that may not be immediately life-threatening or result in 
death or hospitalization but, when based on appropriate medical judgment, may jeopardize 
the subject or may require intervention to prevent one of the outcomes in the definition of 
SAE listed above should also be considered SAEs.  Medical and scientific judgment should 
be exercised in deciding whether expedited reporting is appropriate in such situations. 
For this study, the following events should always be considered serious and reported as an 
important medical event if it does not meet other serious criteria:
•
Serotonin syndrome (must have at least 1 of the following: Spontaneous clonus; 
Inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus)
•
Psychosis
•
Suicidal behavior

•
Priapism
•
New onset valvular heart disease
•
New onset pulmonary hypertension
•
Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas 
of the skin
•
Fibroadenomas of the breast or ductal carcinoma in situ
The following additional study specific AE of interest should be reported using the 
procedures detailed in Reporting of SAEs (Section 9.5.4.1), even if the study specific event 
does not meet serious criteria.  If the event meets seriousness criteria, it should be reported as 
an SAE as above.  However, if the event listed below does not meet serious criteria, it should 
be noted as nonserious on the Adverse Event CRF:  

Suicidal ideation   

Euphoria 
In addition to the above, events associated with special situations include pregnancy or 
exposure to study drug through breastfeeding; AEs associated with study drug overdose, 
misuse, abuse, or medication error.  These events associated with special situations are to be 
captured using the SAE procedures but are to be considered as SAEs only if they meet 1 of 
the above criteria.  All AEs associated with special situations are to be reported on the CRF 
whether or not they meet the criteria for SAEs.  
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization.
The following hospitalizations are not considered to be SAEs because there is no “AE” (ie, 
there is no untoward medical occurrence) associated with the hospitalization:
•
Hospitalizations for respite care
•
Planned hospitalizations required by the protocol  
•
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed after study drug administration)
•
Hospitalization for administration of study drug or insertion of access for 
administration of study drug
•
Hospitalization for routine maintenance of a device (eg, battery replacement) that was 
in place before study entry

VITAL SIGNS AND WEIGHT MEASUREMENTS
Vital sign measurements (ie, systolic and diastolic BP [mmHg], pulse [beats per minute], 
respiratory rate [per minute], body temperature [in centigrade]), and weight (kg) will be 
obtained as designated in the Schedule of Procedures/Assessments (Table 2) by a validated 
method.  BP and pulse will be measured after the subject has been sitting for 5 minutes.  All 
BP measurements should be performed on the same arm, preferably by the same person. 
When vital signs are to be obtained concurrently with PK or other blood samples, the vital 
sign measurements will be performed before drawing blood samples in order to maximize the 
accuracy of blood sampling times while minimizing the potential effects of blood drawing on 
recordings obtained during safety assessments.
9.5.1.5.5
HEIGHT MEASUREMENTS
Height (cm) measurements will be obtained as designated in the Schedule of 
Procedures/Assessments (Table 2).  
9.5.1.5.6
PHYSICAL EXAMINATIONS
Physical
examinations will be performed as 
designated in
the Schedule of 
Procedures/Assessments (Table 2).  Documentation of the physical examination will be 
included in the source documentation at the site.  Significant findings at the Screening Visit 
will be recorded on the Medical History and Current Medical Conditions CRF.  Changes
from screening physical examination findings that meet the definition of an AE will be 
recorded on the Adverse Events CRF.
9.5.1.5.7
ELECTROCARDIOGRAMS
Twelve-lead 
ECGs 
will 
be 
obtained

An ECG abnormality may meet the criteria of an AE as described in this protocol (see
Section 9.5.1.5.1) and the CRF Completion Guidelines.  In these instances, the AE 
corresponding to the ECG abnormality will be recorded on the Adverse Events CRF.
For ECG abnormalities meeting criteria of an SAE (see Section 9.5.1.5.2), the site must fax 
or email the SAE report including the ECG report to the sponsor using the SAE form (see 
Section 9.5.4.1).
9.5.1.5.8
ECHOCARDIOGRAM
Echocardiograms will be obtained on the Schedule of Procedures/Assessments (Table 2). 
Valvular regurgitation in echocardiogram will be rated absent, trace, mild, moderate, or 
severe for the aortic, mitral, and tricuspid valves; the rating will be absent or present for the 
pulmonic valve. The evaluations will be based on guidelines from the American Society of 
Echocardiography. Pulmonary artery pressure will be estimated from the tricuspid 
regurgitant jet velocity.

OTHER SAFETY ASSESSMENTS
WRAML-2
The WRAML-2 administration will consist of the Core Battery, which provides scores on 
Verbal Memory, Visual Memory, and Attention/Concentration.  There are 6 subtests (2 for 
each area).
The tests provide standardized scores based on age and gender, and are 
appropriate for ages 5 to 90 years.  The WRAML-2 will be used to assess lorcaserin effects 
on cognitive function. In addition, signs and symptoms of cognitive related AEs, including 
impairments in attention, memory, and adverse effects on schoolwork will be captured in the 
eCRF.
PHQ-9
The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and 
measuring the severity of depression:

The PHQ-9 incorporates Diagnostic and Statistical Manual of Mental Disorders, 4th 
Edition (DSM-IV) depression diagnostic criteria with other leading major depressive 
symptoms into a brief self-report tool.

The tool rates the frequency of the symptoms which factors into the scoring severity 
index.

Question 9 on the PHQ-9 screens for the presence and duration of suicide ideation.

A follow-up, non-scored question on the PHQ-9 assigns weight to the degree to 
which depressive problems have affected the patient's level of function. 
C-SSRS
The C-SSRS collects information pertinent to suicidal ideation and actions.  It consists of a 
Baseline version which will be administered at baseline and a Since Last Visit version which 
will be administered at the remaining visits.  C-SSRS will be used to assess signal of 
depression and suicidal ideation or behavior. It will be performed at Baseline and at study 
visits as designated in the Schedule of Procedures/Assessments (Table 2).
Signs and symptoms of priapism (painful erection) and hyperprolactinemia (menstrual cycle 
abnormalities or galactorrhea) will be captured in the eCRF.
Hand X-Ray will be evaluated for any potential negative effect on bone age as designated in 
the Schedules/Assessments (Table 2). 
Neuromuscular sign assessment for serotonin 
syndrome will be performed as designated in the Schedule of Procedures/Assessments 
(Table 2) to screen for potential serotonergic syndrome components. 
Serotonergic 
syndromes that meet the diagnostic criteria will be captured by AE eCRF.

9.5.4
Reporting of Serious Adverse Events, Pregnancy, and Events Associated 
with Special Situations
9.5.4.1
Reporting of Serious Adverse Events
All SAEs, regardless of their relationship to study treatment, must be reported on a 
completed SAE form by email or fax as soon as possible but no later than 1 business 
day from the date the investigator becomes aware of the event.
SAEs, regardless of causality assessment, must be collected through the through the last visit
and for 28 days after the subject’s last dose.  All SAEs must be followed to resolution or, if 
resolution is unlikely, to stabilization.  Any SAE judged by the investigator to be related to 
the study treatment or any protocol-required procedure should be reported to the sponsor 
regardless of the length of time that has passed since study completion.
The detailed contact information for reporting of SAEs is provided in the Investigator Study 
File.
For urgent safety issues, please ensure all appropriate medical care is administered to the 
subject and contact the appropriate study team member listed in the Investigator Study File.
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report.  This includes the investigator’s assessment of causality.
Any follow-up information received on SAEs should be forwarded within 1 business day of 
its receipt.  If the follow-up information changes the investigator’s assessment of causality, 
this should also be noted on the follow-up SAE form.
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested by 
the sponsor.
The investigator must notify his/her IRB/IEC of the occurrence of the SAE, in writing, if 
required by their institution.  A copy of this communication must be forwarded to the sponsor 
to be filed in the sponsor’s Trial Master File.
9.5.4.2
Reporting of Pregnancy and Exposure to Study Drug through Breastfeeding
Any pregnancy in which the estimated date of conception is either before the last visit or 
within 28 days of last study treatment or any exposure to study drug through breastfeeding 
during study treatment or within 28 days of last study treatment must be reported.

If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, this 
should be reported regardless of the length of time that has passed since the exposure to study 
treatment.
A congenital anomaly, death during perinatal period, an induced abortion, or a spontaneous 
abortion are considered to be an SAE and should be reported in the same time frame and in 
the same format as all other SAEs (see Section 9.5.4.1).
Pregnancies or exposure to study drug through breastfeeding must be reported by fax or 
email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy.  The contact information for the reporting of pregnancies 
and exposure to study drug through breastfeeding is provided in the Investigator Study File.  
The Pregnancy Report Form must be used for reporting.  All pregnancies must be followed to 
outcome.  The outcome of the pregnancy must be reported as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the outcome.
A subject who becomes pregnant must be withdrawn from the study.

MISUSE, ABUSE, OR MEDICATION ERROR
Adverse events associated with study drug overdose, misuse, abuse, and medication error 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication error are defined as follows:
Overdose
Accidental or intentional use of the study drug in an amount higher
than the protocol-defined dose
Misuse
Intentional and inappropriate use of study drug not in accordance with 
the protocol or authorized dose, route of administration, or 
indication(s) or use of prescription-only study drug without a 
prescription
Abuse
Sporadic or persistent intentional excessive use of study drug 
accompanied by harmful physical or psychological effects
Medication error
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of the 
healthcare professional, subject, or consumer.  Such events may be 
related to professional practice, healthcare products, occupational 
exposure, procedures, or
systems,
including prescribing,
order 
communication,
product
labeling, 
packaging, 
nomenclature,
compounding,
dispensing,
distribution,
administration, education,
monitoring, or use.

All AEs associated with overdose, misuse, abuse, or medication error should be captured on 
the Adverse Event CRF and also reported using the procedures detailed in Section 9.5.4.1
even if the AEs do not meet serious criteria.  Abuse is always to be captured as an AE.  If the 
AE associated with an overdose, misuse, abuse, or medication error does not meet serious 
criteria, it must still be reported using the SAE form and in an expedited manner but should 
be noted as nonserious on the SAE form and the Adverse Event CRF.
9.5.4.3.2
REPORTING OF STUDY-SPECIFIC EVENTS
Study-specific events (listed below) should always be considered as serious important 
medical events and be entered on the Adverse Event CRF and reported using the procedures 
detailed in Reporting of Serious Adverse Events (Section 9.5.4.1), even if the study-specific 
event does not meet other serious criteria.  

Serotonin syndrome
Must have at least 1 of the following: spontaneous clonus; 
inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus

Psychosis

Suicidal behavior 

Priapism

New onset of valvular heart disease

New onset pulmonary hypertension

Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas 
of the skin

Fibroadenomas of the breast or ductal carcinoma in situ
The following additional study specific AE of interest should be reported using the 
procedures detailed in Reporting of SAEs (Section 9.5.4.1), even if the study-specific 
event does not meet serious criteria.  If the event meets seriousness criteria, it should 
be reported as an SAE as above.  However, if the event listed below does not meet 
serious criteria, it should be noted as nonserious on the Adverse Event CRF:  

Suicidal ideation

Euphoria 
9.5.4.4
Expedited Reporting
The sponsor must inform investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (ie, within 
specific time frames).  For this reason, it is imperative that sites provide complete SAE 
information in the manner described above.

9.5.4.5
Breaking the Blind
In the case of a medical emergency where the appropriate treatment of the subject requires 
knowledge of the study treatment given, the investigator may break the randomization code 
for an individual subject.  In all such cases, the AE necessitating the emergency blind break 
will be handled as an SAE in accordance with the procedures indicated above.  Any broken 
code will be clearly justified and documented.  The medical monitor must be notified 
immediately of the blind break.
9.5.4.6
Regulatory Reporting of Adverse Events
Adverse events will be reported by the sponsor or a third party acting on behalf of the 
sponsor to regulatory authorities in compliance with local and regional law and established 
guidance.  The format of these reports will be dictated by the local and regional 
requirements.
9.5.5
Completion/Discontinuation of Subjects
The investigator may withdraw the subject from the study at any time for safety or 
administrative reasons.  A subject may elect to discontinue the study at any time for any 
reason.  All subjects will continue in the study until the 52-week evaluation is completed.  
Subjects who discontinue treatment prematurely will be followed up until study completion.  
All subjects who discontinue the study are to complete the study’s early discontinuation 
procedures indicated in the Schedule of Procedures/Assessments (Table 2).
The investigator will promptly explain to the subject involved that the study will be 
discontinued for that subject and provide appropriate medical treatment and other necessary 
measures for the subject.  A subject who has ceased to return for visits will be followed up by 
mail, phone, or other means to gather information such as the reason for failure to return, the 
status of treatment compliance, the presence or absence of AEs, and clinical courses of signs 
and symptoms.
Subjects who discontinue early from the study will be discontinued for 1 of these primary 
reasons: AE(s), lost to follow-up, subject choice, withdrawal of consent, pregnancy, study 
terminated by sponsor, or other.  In addition to the primary reason, the subject may indicate
1 or more of secondary reasons for discontinuation.  Study disposition information will be 
collected on the Subject Disposition CRF.
Detailed retention strategies will be developed and included in study manual. These include 
a highly trained and competent staff, easy access to the clinic, reminder and follow-up calls, 
interactive group sessions with games and hands-on nutrition and physical activity 
demonstrations, random raffle drawings, social events, birthday and holiday cards, and
newsletters. In addition, home visits for assessments of families will be an option, as needed, 
to maximize data collection. This detailed retention plan will help prevent missing data.
A subject removed from the study for any reason may not be replaced.

9.5.6
Abuse or Diversion of Study Drug
During the study, the investigator will report any concern about abuse or diversion of study 
drugs by completing the Abuse or Diversion of Study Drug CRF.  The DEA Registrant has 
the responsibility to comply with local, state, and Federal laws to notify the Field Division 
Office of the DEA of any theft or significant loss of any controlled substances upon 
discovery of such theft or loss.
9.5.7
Confirmation of Medical Care by Another Physician
The investigator will instruct subjects to inform site personnel when they are planning to 
receive medical care by another physician.  At each visit, the investigator will ask the subject 
whether he or she has received medical care by another physician since the last visit or is 
planning to do so in the future.  When the subject is going to receive medical care by another 
physician, the investigator, with the consent of the subject, will inform the other physician 
that the subject is participating in the clinical study.
9.6
Data Quality Assurance
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines.  Site audits 
will be made periodically by the sponsor’s or the CRO’s qualified compliance auditing team, 
which is an independent function from the study team responsible for conduct of the study.
9.6.1
Data Collection
Data required by the protocol will be collected on the CRFs and entered into a validated data 
management system that is compliant with all regulatory requirements.  As defined by ICH 
guidelines, the CRF is a printed, optical, or electronic document designed to record all of the 
protocol-required information to be reported to the sponsor on each study subject.
Data collection on the CRF must follow the instructions described in the CRF Completion 
Guidelines.  The investigator has ultimate responsibility for the collection and reporting of all 
clinical data entered on the CRF.  The investigator or designee as identified on Form 
FDA 1572 must sign the completed CRF to attest to its accuracy, authenticity, and 
completeness.
Completed, original CRFs are the sole property of Eisai and should not be made available in 
any form to third parties without written permission from Eisai, except for authorized 
representatives of Eisai or appropriate regulatory authorities.
9.6.2
Clinical Data Management
All software applications used in the collection of data will be properly validated following 
standard computer system validation that is compliant with all regulatory requirements.  All 
data, both CRF and external data (eg, laboratory data), will be entered into a clinical system.

9.7.1.4
Demographic and Other Baseline Characteristics
Demographic and other baseline characteristics for the FAS and Safety Analysis Sets will be 
summarized for each treatment group using descriptive statistics or frequency count.  
Continuous demographic and baseline variables include age, height, BMI, waist 
circumference, and weight; categorical variables include sex and race.
9.7.1.5

All investigator terms for medications recorded in the CRF will be coded to an 11-digit 
character code using the World Health Organization Drug Dictionary.  The number 
(percentage) of subjects who took prior and concomitant medications will be summarized for
the Safety Analysis Set by treatment group, Anatomical Therapeutic Chemical class, and 
World Health Organization Drug Dictionary preferred term (PT).  Prior medications will be 
defined as medications that stopped before the first dose of study drug.  Concomitant 
medications will be defined as medications that started on or after the date of the dosing of 
study drug and continued up to 30 days afterward.
9.7.1.6
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, while the PP will 
be used as a supportive analysis.  Unless specified otherwise, a 2-sided α=0.05 significance 
level will be used for all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change 
from baseline in BMI will be analyzed using analysis of covariance model (ANCOVA) with 
factors of treatment, sex (male and female) as fixed effect, and the baseline age and BMI as 
covariates.  The missing values will be imputed using a pattern mixture model utilizing 
multiple imputation (MI) assuming the missing values are missing not at random (MNAR).  
The missing values will be imputed at each visit using all available values including the 
retrieved measurement from the postdiscontinuation data.  The details of the analysis model 
and missing value imputation method will be further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis: The same primary efficacy analyses described above will be repeated 
based on the PP.

Change from baseline in standardized BMI score (Z-score):
The same primary 
efficacy analyses described above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed 
and will be described in the SAP.

Key Secondary Efficacy Analysis
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 
5% BMI reduction at Week 52.  The secondary efficacy endpoint will be analyzed only if the 
test for the primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be 
analyzed using a logistic regression model with factors of treatment, and sex (male and 
female), and baseline BMI as a covariate using FAS.  Subjects with any missing assessment 
at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be 
analyzed using mixed effect model repeated measurement analysis (MMRM) and categorical
variables will be analyzed using the Cochran Mantel Haenszel test, Chi-square test, or 
logistic regression as appropriate.  Additional analysis may be performed as needed using 
appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male 
and female), race (white, black, Asian, and other). Additional subgroups may be explored, if 
deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and 
sensitivity analyses.
9.7.1.7
Pharmacokinetic, Pharmacodynamic, Pharmacogenomic, and Other Biomarker
Analyses
9.7.1.7.1
PHARMACOKINETIC ANALYSES
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling.  The effect of covariates, such as baseline characteristics
or demographics, on PK will be explored.  Derived exposure parameters such as the 
maximum observed concentration and the area under the concentration-time curve from time
0 to 24 hours at steady-state will be calculated from the final PK model using individual 
posterior estimates of the PK parameters and from dosing history.  The PK analysis set will 
be used for this analysis.
9.7.1.7.2
PHARMACODYNAMIC ANALYSES
Change from Baseline in BMI will be assessed as the PD analysis.  The PD analysis set will 
be used for this analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% 
and ≥10% BMI reduction, and change in waist circumference from baseline) will also be 
assessed as part of the PD analysis.  The PK/PD analysis set will be used for this analysis.

PHARMACOKINETIC/PHARMACODYNAMIC ANALYSES
Population PK/PD modeling will be used to explore the relationship between lorcaserin 
plasma exposure and response, including but not limited to change in BMI from baseline and 
the probability of achieving at least a 5% and at least a 10% change in BMI from baseline to 
Week 52.  Additionally, exposure-safety relationships for select safety parameters may be 
explored graphically, depending on the data at the end of study.  Any emergent relationship 
may be modeled as appropriate.  Any parameters based on the study data may be considered 
for exploratory assessment for its relationship to PK.
9.7.1.7.4
PHARMACOGENOMIC AND PHARMACOGENETIC ANALYSES
Not applicable
9.7.1.8
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments 
including the incidence of AEs (including changes from baseline in physical examination), 
growth (CDC growth chart and bone age determined by x-ray of the hand), sexual maturation 
(Tanner Staging), out-of-normal-range laboratory safety test values, change from baseline in 
laboratory safety test values, ECGs, and vital sign measurements will be summarized by 
treatment group using descriptive statistics or frequency count as appropriate.  In addition, 
cognitive function will be evaluated by the WRAML-2, depression will be evaluated by the 
PHQ-9, and suicidal ideation and behavior will be evaluated by the C-SSRS, and will also be 
summarized by treatment group using descriptive statistics or frequency count as appropriate.  
All WRAML-2 raw scores from the Core Battery will be converted to age and gender 
standard scores for purposes of intra individual comparisons.  For echocardiographic 
assessments, the proportion of subjects who develop FDA-defined valvulopathy, the 
proportion of subjects who develop pulmonary hypertension [pulmonary hypertension is 
defined when the subject’s systolic pulmonary artery pressure (SPAP) ≥40 mmHg evaluated 
by echocardiograph], and change from baseline in SPAP will be summarized by treatment 
group at Week 28 and Week 52 using descriptive statistics or frequency count as appropriate.
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
9.7.1.8.1
EXTENT OF EXPOSURE
Subjects will receive Belviq XR 20 mg or placebo QD for up to 52 weeks. The extent of 
exposure will be characterized by duration of exposure (in weeks) for each treatment group.
Duration of exposure will be defined as the number of weeks between the date the subject 
received the 1st dose of study drug and the date the subject received the last dose of study 
drug.  Duration of exposure will be summarized using descriptive statistics by treatment 
group.  In addition, the duration of exposure will be categorized and will be summarized 
using frequency count by treatment group.

ADVERSE EVENTS
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities 
(MedDRA).  Adverse events will be coded to the MedDRA (Version 18.0 or higher) lower 
level term closest to the verbatim term.  The linked MedDRA PT and primary system organ 
class (SOC) are also captured in the database.
A treatment-emergent AE (TEAE) is defined as an AE that emerges during treatment (up to 
28 days after the last dose of study drug), having been absent at pretreatment (Baseline) or 
•
Reemerges during treatment (up to 28 days after the last dose of study drug), having been 
present at pretreatment (Baseline) but stopped before treatment, or 
•
Worsens in severity during treatment relative to the pretreatment state, when the AE is 
continuous.
Only those AEs that were treatment emergent will be included in summary tables.  All AEs, 
treatment emergent or otherwise, will be presented in subject data listings.
The TEAEs will be summarized by treatment group.  The following summaries will be 
reported for TEAES:

Incidence of TEAEs in descending order of frequency

Incidence of TEAEs by SOC and PT

Incidence of treatment-related TEAEs by SOC and PT

Incidence of TEAEs by SOC, PT and maximum severity (mild, moderate, or severe)

Incidence of treatment-related TEAEs by SOC, PT, and maximum severity (mild, 
moderate, or severe)

Incidence of TEAEs by SOC, PT, and relationship to study drug (Yes [related] or No 
[not related]) 
A subject will be counted only once within a SOC or PT, if the subject experienced more 
than 1 TEAE within a specified SOC and PT.

In addition, subjects with TEAEs leading to discontinuation from study drug and AEs of 
special interest as described in Section 9.5.4.3.2 will be summarized by MedDRA SOC and 
PT for each treatment group. 
9.7.1.8.3
LABORATORY VALUES
Laboratory results will be summarized using Système International units, as appropriate.  For 
all quantitative parameters listed in Section 9.5.1.5.3, the actual value and the change from 
baseline to each postbaseline visit and to the end of treatment (defined as the last 
on-treatment value) will be summarized by visit and treatment group using descriptive 
statistics.  Percentages will be based on the number of subjects with both nonmissing 
baseline and relevant postbaseline results.
Laboratory test results will be assigned a low/normal/high (LNH) classification according to 
whether the value was below (L), within (N), or above (H) the laboratory parameter’s 
reference range.  Within-treatment comparisons for each laboratory parameter will be based 
on 3-by-3 tables (shift tables) that compare the baseline LNH classification to the LNH 
classification at the End of Treatment and the Follow-Up visits.  Similar shift tables will also 
compare the baseline LNH classification to the LNH classification for the highest and lowest 
value during the treatment period.
Appendix 1
presents the criteria that will be used to identify subjects with 
treatment-emergent markedly abnormal laboratory values (TEMAV).  Except for phosphate, 
a TEMAV is defined as a postbaseline value with an increase from baseline to a grade of 2 or 
higher.  For phosphate, a TEMAV was defined as a postbaseline value with an increase from 
baseline to a grade of 3 or higher.  When displaying the incidence of TEMAVs, each subject 
may be counted once in the laboratory parameter high and in the laboratory parameter low 
categories, as applicable.
9.7.1.8.4
VITAL SIGNS
Descriptive statistics for vital signs parameters (eg, systolic and diastolic BP, pulse, 
respiratory rate, temperature, weight) and changes from baseline will be presented by visit

For each ECG parameter (including PR interval, RR interval, QRS interval, QT interval, QTc
interval (Bazett formula), QTc interval (Fridericia formula), and heart rate), the actual value 
and change from baseline will be summarized by visit and treatment group using descriptive 
statistics. 
Shift tables will present changes from baseline in ECG interpretation (categorized as normal; 
abnormal, not clinically significant; and abnormal, clinically significant) to end of treatment. 
Maximum postbaseline QTc (Bazett) and QTc (Fridericia) will also be tabulated by treatment 
group as follows:

Number (percentage) of subjects in greater than 450 msec, greater than 480 msec, and 
greater than 500 msec during the treatment, and

Number (percentage) of subjects with an increment of greater than 30 msec and 
greater than 60 msec from the baseline visit.
9.7.1.8.6
OTHER SAFETY ANALYSES
Other safety assessments including adolescent growth evaluations using 95th percentile CDC 
growth charts and bone age using x-ray of the hand, sexual maturation as measured in Tanner 
Staging, neuromuscular sign assessment for serotonin syndrome, signs and symptoms of 
priapism and prolactinemia, study drug effect on cognitive function assessed by WRAML-2, 
assessment of suicidality using C-SSRS, and depression assessment using PHQ-9 will be 
summarized by treatment group at each scheduled visit.  For echocardiographic assessments, 
the proportion of subjects who develop FDA-defined valvulopathy, the proportion of subjects 
who develop pulmonary hypertension (defined as when a subject’s SPAP is ≥40 mmHg 
evaluated by echocardiograph], and change from baseline in SPAP will also be summarized 
by treatment group at Week 28 and Week 52.
9.7.2
Determination of Sample Size
The proposed sample size is based on the comparison of the primary efficacy endpoint, 
change from Baseline in BMI at Week 52 between the Belviq XR 20-mg treatment group and 
placebo group.  Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 
360 subjects in a 1:1 ratio (n=180 in the Belviq XR 20-mg treatment group; n=180 in the 
placebo group) will have at least 90% power to detect a treatment difference of 1 kg/m2 in 
BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at 
least a 5% BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, 
this sample of 360 subjects (180 subjects for Belviq XR 20 mg and 180 subjects for placebo) 
will also have greater than 85% power to detect an absolute difference of 20% between the 
Belviq XR 20-mg group and placebo group, using a 2-sided Fisher’s Exact test with α=0.05.  
The assumption used in the sample size calculation is based on the 2 pivotal lorcaserin 
studies, APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

11 PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE 
PROCEDURES)
11.1
Changes to the Protocol
Any change to the protocol requires a written protocol amendment or administrative change 
that must be approved by the sponsor before implementation.  Amendments specifically 
affecting the safety of subjects, the scope of the investigation, or the scientific quality of the 
study require submission to health or regulatory authorities as well as additional approval by 
the applicable IRBs/IECs.  These requirements should in no way prevent any immediate 
action from being taken by the investigator, or by the sponsor, in the interest of preserving 
the safety of all subjects included in the study.  If the investigator determines that an 
immediate change to or deviation from the protocol is necessary for safety reasons to 
eliminate an immediate hazard to the subjects, the sponsor’s medical monitor and the 
IRB/IEC for the site must be notified immediately.  The sponsor must notify the health or 
regulatory authority as required per local regulations.
Protocol amendments that affect only administrative aspects of the study may not require 
submission to health or regulatory authority or the IRB/IEC, but the health or regulatory 
authority and IRB/IEC should be kept informed of such changes as required by local 
regulations.  In these cases, the sponsor may be required to send a letter to the IRB/IEC and 
the Competent Authorities detailing such changes.
11.2
Adherence to the Protocol
The investigator will conduct the study in strict accordance with the protocol (refer to ICH 
E6, Section 4.5).
11.3
Monitoring Procedures
The sponsor’s/CRO’s CRA will maintain contact with the investigator and designated staff 
by telephone, letter, or email between study visits.  Monitoring visits to each site will be 
conducted by the assigned CRA as described in the monitoring plan.  The investigator will 
allow the CRA to inspect the clinical, laboratory, and pharmacy facilities to assure 
compliance with GCP and local regulatory requirements.  The CRFs and subject’s 
corresponding original medical records (source documents) are to be fully available for 
review by the sponsor’s representatives at regular intervals.  These reviews verify adherence 
to study protocol and data accuracy in accordance with local regulations.  All records at the 
site are subject to inspection by the local auditing agency and IRB/IEC review.

Page 72 of 81
In accordance with ICH E6, Section 1.52, source documents include, but are not limited to 
the following:
•
Clinic, office, or hospital charts
•
Copies or transcribed health care provider notes which have been certified for accuracy 
after production
•
Recorded data from automated instruments such as IxRS, x-rays, and other imaging 
reports, (eg, sonograms, computerized tomography scans, magnetic resonance images, 
radioactive images, ECGs, rhythm strips, EEGs, polysomnographs, pulmonary function
tests) regardless of how these images are stored, including microfiche and photographic 
negatives
•
Pain, quality of life, or medical history questionnaires completed by subjects
•
Records of telephone contacts
•
Diaries or evaluation checklists
•
Drug distribution and accountability logs maintained in pharmacies or by research 
personnel
•
Laboratory results and other laboratory test outputs (eg, urine pregnancy test result 
documentation and urine dip-sticks)
•
Correspondence regarding a study subject’s treatment between physicians or memoranda 
sent to the IRBs/IECs
•
CRF components (eg, questionnaires) that are completed directly by subjects and serve as 
their own source
11.4
Recording of Data
A CRF is required and must be completed for each subject by qualified and authorized 
personnel.  All data on the CRF must reflect the corresponding source document, except 
when a section of the CRF itself is used as source document.  Any correction to entries made 
on the CRF must be documented in a valid audit trail where the correction is dated, the 
individual making the correct is identified, the reason for the change is stated, and the 
original data are not obscured.  Only data required by the protocol for the purposes of the 
study should be collected.
The investigator must sign each CRF.  The investigator will report the CRFs to the sponsor 
and retain a copy of the CRFs.
11.5
Identification of Source Data
All data to be recorded on the CRF must reflect the corresponding source documents.

11.6
Retention of Records
The circumstances of completion or termination of the study notwithstanding, the 
investigator is responsible for retaining all study documents, including but not limited to the 
protocol, copies of CRFs, the Investigator's Brochure, and regulatory agency registration 
documents (eg, Form FDA 1572 ICFs, and IRB/IEC correspondence).  In addition, the 
sponsor will send a list of treatment codes by study subject to the investigator after the 
clinical database for this study has been locked.  The site should plan to retain study 
documents, as directed by the sponsor, for at least 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region or at least 3 years have elapsed since the formal 
discontinuation of clinical development of the investigational product.
It is requested that at the completion of the required retention period, or should the 
investigator retire or relocate, the investigator contact the sponsor, allowing the sponsor the 
option of permanently retaining the study records.
11.7
Auditing Procedures and Inspection
In addition to the routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of ICH GCP and all applicable local 
regulations.  If a government regulatory authority requests an inspection during the study or 
after its completion, the investigator must inform the sponsor immediately.
11.8
Handling of Study Drug
All study drugs will be supplied to the PI (or a designated pharmacist) by the sponsor.  Drug 
supplies must be kept in an appropriate secure area (eg, locked cabinet) and stored according 
to the conditions specified on the drug labels.  Investigational product will be stored in 
accordance with the DEA Regulations for Scheduled III - V Drugs and labeled storage 
conditions.  The investigator (or a designated pharmacist) must maintain an accurate record 
of the shipment and dispensing of the study drug in a drug accountability ledger, a copy of 
which must be given to the sponsor at the end of the study.  An accurate record of the date 
and amount of study drug dispensed to each subject must be available for inspection at any 
time.  The CRA will visit the site and review these documents along with all other study 
conduct documents at appropriate intervals once study drug has been received by the site.
All drug supplies are to be used only for this study and not for any other purpose. The 
investigator (or site personnel) must not destroy any drug labels or any partly used or unused 
drug supply before approval to do so by the sponsor.  At the conclusion of the study and as 
appropriate during the study, the investigator (or a designated pharmacist) will return all used 
and unused drug containers, drug labels, and a copy of the completed drug disposition form 
to the sponsor’s CRA.

Family-Based Lifestyle Program
Program Overview
All subjects and their caregivers (participating parent or guardian) in Study 403 will be 
encouraged to participate in a standardized weight management program for adolescents 
consisting of multicomponent behavior therapy.  The therapy will focus on healthy eating, 
physical activity, and lifestyle changes that will facilitate weight loss and weight-loss 
maintenance. The role of the caregivers is to support their child or adolescents’ lifestyle 
changes and their taking of study medication.
The objectives of this program are as follows:

Develop a weight management program for all Belviq XR study participants and their 
caregivers (caregivers are instructed in methods to support their adolescents’ progress 
but caregivers are themselves not instructed to lose weight or take medication)

Standardize the weight management program across all study sites

Maximize participant retention

Promote participant’s adherence to both taking study medication and following the 
lifestyle program

parameters including but not limited to reduction from baseline in BMI and probability of 
achieving at least a 5% and at least a 10% reduction in BMI from baseline at Week 52 using 
population PK/ PD modeling
Study Design
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in obese
adolescents, ages 12 to 17 years.  Approximately 360 subjects will be randomized in a 1:1 ratio to 
Belviq XR 20 mg QD (180 subjects) and placebo (180 subjects).  Subjects will be stratified by sex.  
Subjects will receive Belviq XR 20 mg or placebo QD in a 1:1 ratio for up to 52 weeks. Throughout 
the duration of the study, subjects will be encouraged to adhere to a lifestyle modification program 
that includes a standardized, age-appropriate diet and exercise counseling.
The study will consist of 2 phases: Prerandomization and Randomization.  The Prerandomization 
Phase will last up to 30 days and consist of 1 visit during which subjects will be screened for 
eligibility.  The Randomization Phase consists of a Treatment Period and a Follow-Up Period.  The 
Treatment Period will last for a maximum of 52 weeks, with visits at Weeks 1, 5, 8, 12, 20, 28, 36,
44, and 52.  The Follow-Up Period will extend from the End of Treatment visit to the End of Study 
visit.
Subjects who screen fail can be re-screened only once after 60 days.  All subjects will continue in the 
study until the 52-week evaluation is completed.  Subjects who discontinue treatment prematurely 
will be followed up until study completion.  
Number of Subjects
Approximately 700 subjects will be screened to provide 360 randomized subjects.
Inclusion Criteria
1.
Healthy male or female adolescents, age 12 to 17 years at Screening, with a BMI that is 
greater than or equal to the United States (US)-weighted mean of the 95th percentile based on 
age and sex with a body weight greater than 60 kg
2.

3.
Any of the following findings on Screening echocardiography:

Aortic regurgitation mild or greater


Pharmacokinetic Assessments
Plasma lorcaserin concentrations will be measured at Weeks 12, 28, 36, and 52 for analysis of 
population PK.  All subjects will be instructed to take their study drug in the morning on the day 
before their scheduled clinic visit at Weeks 12, 28, 36, and 52.  No additional doses should be taken 
that day for those subjects who have been taking their doses in the evening.  Dose times must be 
recorded for the last 2 dosing times prior to the clinic visit.
On the day of the Week 12, 28, and 52 clinic visits, subjects will be instructed to take their study drug 
at approximately the same time as the morning before, with no additional doses taken that day.  Two 
blood samples for determination of plasma concentrations of lorcaserin will be taken at each of these 
visits: within 30 minutes before dosing and within 1 to 3 hours after dosing.  
On the day of the Week 36 clinic visit, subjects will take their study drug in the morning at home.  
One blood sample for determination of plasma concentrations of lorcaserin will be collected at the 
clinic within 4 to 6 hours after dosing.
Subjects can resume their usual dose schedule the day after the PK clinic visits.  
Pharmacodynamic Assessments

Change from baseline in BMI 

Proportion (%) of subjects achieving at least a 5% and at least a 10% reduction in BMI
Other PD endpoints will be considered based on the data at the end of the study to explore their 
relationships with lorcaserin plasma exposure.
Pharmacogenomic/Pharmacogenetic Assessments
Not applicable
Safety Assessments
Safety assessments will consist of monitoring and recording all adverse events (AEs) and serious 
adverse events (SAEs); electrocardiograms (ECGs); laboratory evaluation for hematology, metabolic 
function (glucose, fasting lipids, and thyroid), adrenal function and biochemical blood and urine bone 
health assessments; blood chemistry and urine values; neuropsychiatric events; periodic measurement 
of vital signs, neuromuscular signs for screening potential serotonin syndrome, and signs or 
symptoms of priapism and prolactinemia; and performance of physical examinations.
In patients 
with potential prolactin-related AEs, such as galactorrhea, changes in libido, or changes to menstrual 
cycle, prolactin level will be measured and assessed. Study drug effect on growth will be evaluated 
using the CDC growth chart at Baseline, and Weeks 5, 12, 28, 36, 52, and at Follow-Up; a full 
physical examination, at Baseline, Weeks 12, 28, 52, and at Follow-Up; and bone age determination 
by x-ray of the hand at Baseline, Weeks 12, 28, and 52. Sexual maturation will be evaluated by 
assessing sex hormones and self-reported changes in Tanner Staging at Baseline, Weeks 28 and 52, 
and at Follow-Up.   
The C-SSRS will be used to assess all subjects in the study for any signal of depression or suicidal 
ideation or behavior.  Additionally, screening, diagnosing, monitoring, and measuring the severity of 
depression will be assessed using the PHQ-9 and effects on cognitive function will be assessed using

WRAML-2.
Echocardiographic assessments will be used to exclude subjects with FDA-defined valvulopathy, 
pulmonary hypertension, and other major cardiovascular disease (as outlined in Exclusion Criterion 
No. 3) during the Screening Period.  Additionally, cardiac valvular function and pulmonary systolic 
pressure changes at Weeks 28 and 52 will be assessed.
Valvular regurgitation as assessed in the 
echocardiogram will be rated absent, trace, mild, moderate, or severe for the aortic, mitral, and 
tricuspid valves; the rating will be absent or present for the pulmonic valve. The evaluations will be 
based on guidelines from the American Society of Echocardiography. Pulmonary artery pressure will 
be estimated from the TR jet velocity.
Bioanalytical Methods
Lorcaserin will be quantified in plasma using a validated liquid chromatography method coupled with 
tandem mass spectrometry.


The Full Analysis Set (FAS) is the group of all randomized subjects regardless of adherence to 
study drug.

Per-Protocol Analysis Set (PP) is the group of all randomized subjects who are 80% or greater 
compliant with study medication, completed the study, have no major protocol deviations, have 
no violations of inclusion or exclusion criteria, and have BMI data at Baseline and Week 52.  
The determination of subjects to be excluded from this population based on the above criteria 
and a list of major protocol violations will be included in the statistical analysis plan (SAP) and 
finalized before data base lock.

The PD Analysis Set is the group of subjects who had sufficient PD data to derive at least 1 PD 
parameter.

The PK Analysis Set is the group of all randomized subjects from whom at least 1 valid 
lorcaserin plasma concentration was obtained with associated documented dosing history.

The population PK/PD set is the group of randomized subjects with PK information and who 
have at least 1 adequately documented measurement of BMI.
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, and the PP will be used as 
a supportive analysis.  Unless otherwise specified, a 2-sided α=0.05 significance level will be used in 
all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change from 
baseline in BMI will be analyzed using the repeated measures analysis of covariance model 
(ANCOVA) with factors of treatment visits (Baseline, Week 1, 5, 8, 12, 20, 28, 36, 44, and 52), , sex 
(male and female), treatment-by-visit interaction as fixed effect, subjects as random effect, and the 
baseline age and BMI as covariates.  The missing values will be imputed using a pattern mixture 
model utilizing multiple imputation (MI) using the same model as the analysis model.  The missing 
values will be imputed for a visit at a time using the complete cases up to and include the current visit 
for a particular visit.  The unstructured covariance matrix will be used in the analysis and the 
treatment comparison at Week 52 will be the event of interest.  In case of a convergence issue, the 
Toeplitz covariance structure will be used in the model.  As a sensitivity analysis, the missing values 
will also be imputed using pattern mixture MI method assuming the missing value is missing not at 
random (MNAR). The details of the analysis model and missing value imputation method will be 
further described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis:  The same primary efficacy analyses described above will be repeated based on 
the PP.

Change from baseline in standardized BMI score (Z-score):  The same primary efficacy 
analyses described above will be repeated using Z-score.
Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed and will 
be described in the SAP.

The key secondary efficacy endpoint is the proportion of subjects achieving at least a 5% BMI
reduction at Week 52. The secondary efficacy endpoint will be analyzed only if the test for the 
primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be analyzed using 
a logistic regression model with factors of treatment, sex (male and female), and baseline BMI as a 
covariate using FAS.  Subjects with any missing assessment at Week 52 will be considered as 
treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be analyzed 
using mixed effect model repeated measurement analysis (MMRM) and categorical variables will be 
analyzed using the Cochran Mantel Haenszel test, Chi-square test, or logistic regression as 
appropriate.  Additional analysis may be performed as needed using appropriate statistical 
methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male and 
female), and race (white, black, Asian, and other).  Additional subgroups may be explored, if deemed 
necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and sensitivity 
analyses.
Pharmacokinetic Analyses
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling. The effect of covariates such as baseline characteristics or 
demographics on PK will be explored. Derived exposure parameters such as the maximum observed 
concentration and the area under the concentration-time curve from time 0 to 24 hours at steady-state 
will be calculated from the final PK model using individual posterior estimates of the PK parameters 
and from dosing history. The PK analysis set will be used for this analysis.
Pharmacodynamic Analyses
Change from Baseline in BMI will be assessed as the PD analysis.  The PD analysis set will be used 
for this analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% and 
≥10% BMI reduction, and change in waist circumference from baseline) will also be assessed as part 
of the PD analysis.  The PK/PD analysis set will be used for this analysis.
Pharmacokinetic/Pharmacodynamic Analyses
Population PK/PD modeling will be used to explore the relationship between lorcaserin plasma 
exposure and response, including but not limited to change in BMI from baseline and the probability 
of achieving at least a 5% and at least a 10% change in BMI from baseline to Week 52.  Additionally, 
exposure-safety relationships for select safety parameters may be explored graphically depending on 
the data at the end of study.  Any emergent relationship may be modeled as appropriate.  Any 
parameters based on the study data may be considered for exploratory assessment for its relationship 
to PK.

Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments including the 
incidence of AEs (including changes from baseline in physical examination), growth (CDC growth 
chart and bone age determined by x-ray of the hand), sexual maturation (Tanner Staging), 
out-of-normal-range laboratory safety test values, change from baseline in laboratory safety test 
values, ECGs, and vital sign measurements will be summarized by treatment group using descriptive 
statistics or frequency count as appropriate.  In addition, cognitive function will be evaluated by the
WRAML-2, depression will be evaluated by the PHQ-9, and suicidal ideation and behavior will be 
evaluated by the C-SSRS, and will also be summarized by treatment group using descriptive statistics 
or frequency count as appropriate.
All WRAML-2 raw scores from the Core Battery will be 
converted to age and gender standard scores for purposes of intra individual comparisons. For 
echocardiographic assessments, the proportion of subjects who develop FDA-defined valvulopathy, 
the proportion of subjects who develop pulmonary hypertension [pulmonary hypertension is defined 
when the subject’s systolic pulmonary artery pressure (SPAP) ≥40 mmHg evaluated by 
echocardiograph], and change from baseline in SPAP will be summarized by treatment group at 
Week 28 and Week 52 using descriptive statistics or frequency count as appropriate.
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.

Sample Size Rationale
The proposed sample size is based on the comparison of the primary efficacy endpoint, change in 
BMI from Baseline to Week 52 between the Belviq XR 20-mg treatment group and placebo group.  
Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 360 subjects in a 1:1 ratio 
(n=180 in the Belviq XR 20-mg treatment group; n=180 in the placebo group) will have at least 
90% power to detect a treatment difference of 1 kg/m2 in BMI, using a 2-sided t-test with α=0.05.  
Assuming the proportion of subjects achieving at least a 5% BMI reduction at Week 52 is 20% for 
the placebo group and a 40% dropout rate, this sample of 360 subjects (180 subjects for Belviq XR 
20 mg and 180 subjects for placebo) will also have greater than 85% power to detect an absolute 
difference of 20% between the Belviq XR 20-mg group and the placebo group, using a 2-sided 
Fisher’s Exact test with α=0.05. The assumption used in the sample size calculation is based on the 
2 pivotal lorcaserin studies APD356-009 and APD356-011 in obese and overweight non-diabetic 
adult subjects.

ETHICS
5.1
Institutional Review Boards/Independent Ethics Committees
The protocol, Informed Consent Form (ICF), and appropriate related documents must be 
reviewed and approved by an Institutional Review Board (IRB) or Independent Ethics 
Committee (IEC) constituted and functioning in accordance with International Conference on 
Harmonisation (ICH) Good Clinical Practice (ICH E6), Section 3, and any local regulations 
(eg, Federal Regulations, Title 21 Code of Federal Regulations [21 CFR] Part 56).  Any 
protocol amendment or revision to the ICF will be resubmitted to the IRB/IEC for review and 
approval, except for changes involving only logistical or administrative aspects of the study 
(eg, change in clinical research associate [CRA], change of telephone number[s]).  
Documentation of IRB/IEC compliance with the ICH E6 and any local regulations regarding 
constitution and review conduct will be provided to the sponsor.
A signed letter of study approval from the IRB/IEC chairman must be sent to the principal 
investigator (PI) with a copy to the sponsor before study start and the release of any study 
drug to the site by the sponsor or its designee (ICH E6, Section 4.4).  If the IRB/IEC decides 
to suspend or terminate the study, the investigator will immediately send the notice of study 
suspension or termination by the IRB/IEC to the sponsor.
Study progress is to be reported to IRB/IECs annually (or as required) by the investigator or

INTRODUCTION
7.1
Indication
Obesity
Obesity has become a global epidemic in western civilization, causing a serious public health 
concern.  In the United States, the prevalence of obesity in adolescents ages 12 and 19 years
has almost doubled over the past 2 decades.  The rate increased from 10.5% between 1988 
and 1994 to 20.5% between 2011 and 2012 (CDC/NCHS, 2013).  Obesity in adolescents, 
defined in the United States as greater than or equal to the 95th percentile in gender- and 
age-specific body mass index (BMI), continues to grow at an alarming rate in the United 
States and globally.  Based on data (Wang and Lobstein, 2006) using various criteria for the 
definition of obesity that included more than 30 countries in Europe, North America, Asia, 
and the West Pacific, prevalence of obesity in these countries has also increased 
significantly, at a rate comparable to that in the United States.
Adolescent obesity has many negative implications for both the health and well-being of the 
individual as well as for society.  These include increased susceptibility to a host of diseases, 
chronic health disorders, psychological disorders, and premature death (Flegal, et al., 2005; 
Rofey, et al., 2009).  Increases in the prevalence of overweight and obese adolescents may 
result in a decrease in life expectancy for the 1st time in 200 years (Peeters, et al., 2003).
As a result, there is a significant impact on the cost of healthcare.  It is estimated that medical 
costs due to overweight adolescents are approximately $14 billion per year in the United 
States (Trasande and Chatterjee, 2009).  Obesity-related medical costs in general are
expected to rise significantly because today’s obese adolescents are likely to become 
tomorrow’s obese adults (Whitaker, et al., 1997).
Current approaches to weight management in adults include lifestyle modification, 
pharmacotherapy, and invasive bariatric procedures.  Lifestyle modification involves a 
combination of diet, exercise, and behavioral change, and is the preferred and essential 
strategy for weight management in obese and overweight individuals, including adolescents.  
Although lifestyle modification can be very efficacious in some patients, adherence to the 
prescribed regimens is often poor.  As such, lifestyle modification alone is often not adequate 
and the weight loss is often transient.  On the other hand, bariatric surgery and various other 
invasive procedures are generally reserved for the severely obese population. 
Pharmacotherapy can play a significant role in weight management programs, and is often 
combined with lifestyle modification to enhance weight loss beyond that which is normally 
achieved with diet and exercise alone.  Current pharmacotherapies offer the potential to 
significantly augment weight loss when combined with diet and exercise, but are rarely used
for adolescents.
The current standard of care for treatment of obesity in adolescent subjects ranges from
behavioral therapy including lifestyle intervention to the rare use of pharmacotherapy in

adolescents over 12 years of age (McGovern, et al, 2008; Spear, et al, 2007).  Xenical®
(orlistat) is currently the only product available for weight control in obese adolescent 
patients 12 to 16 years of age.  However, it is associated with gastrointestinal side effects 
(Xenical PI. 2015), and the treatment effect of Xenical is modest. In a study that included 
539 obese adolescents with BMI above the 97th percentile, Xenical demonstrated a 0.86 BMI 
reduction relative to placebo after 52 weeks of treatment (-0.55 BMI in the Xenical treatment 
group versus +0.31 BMI in the placebo group) (FDA, 2003; Chanoine, et al, 2005).
Obtaining maximum retention in the study is a major goal in order to minimize missing data.  
A number of strategies have been used in prior adolescent weight loss studies that will be 
used in the present study to help retain participants.  These include a highly trained and 
competent staff, ample waiting area, readily available parking (at no cost), access to mass 
transit, and reminder and follow-up calls.  In addition, we will provide fun and interactive 
group sessions with games and hands-on nutrition and physical activity demonstrations, 
random raffle drawings, social events, birthday and holiday cards, and newsletters.  
Furthermore, we will make home visits for assessments of families, as needed, to maximize 
data collection. 
By using these retention strategies, we hope that we will maximize 
participant retention, which will help us cope with missing data.
7.1.1
APD356/Belviq (lorcaserin hydrochloride)
7.1.1.1
Mechanism of Action
Belviq is a selective serotonin 2c receptor agonist which was approved by the US Food and 
Drug Administration (FDA) on 27 Jun 2012 as an adjunct to a reduced-calorie diet and 
increased physical activity for chronic weight management in adult patients with a BMI of at 
least 30 kg/m2 (obese), or adult patients with a BMI greater than or equal to 27 kg/m2
(overweight) in the presence of at least 1 weight-related comorbid condition.
7.1.1.2
Clinical Experience with APD356/Belviq (lorcaserin hydrochloride)
The Phase 3 clinical evaluation of Belviq in studies of more than 7700 adult subjects, 
including 604 subjects with Type 2 diabetes mellitus, demonstrated clinically meaningful 
efficacy and a safety profile that includes minimal and easily managed risks.  In each of the 
individual studies and in the pooled efficacy analyses, the Belviq dose met the following 
prespecified endpoints:

A significantly greater proportion of adult subjects taking Belviq 10 mg twice per day 
(BID) (47%) lost at least 5% of baseline body weight at 52 weeks as compared to 
subjects taking placebo (23%).  A significantly greater proportion of subjects taking 
Belviq 10 mg BID (22.4%) lost at least 10% of baseline body weight at 1 year as 
compared to subjects taking placebo (8.7%). 

The mean weight loss at 1 year in adult subjects taking Belviq 10 mg BID (-5.8 kg) 
was significantly greater than that in subjects taking placebo (-2.5 kg).
An integrated evaluation of the data from the pediatric, adolescent, and adult subjects 
revealed that the relationship between lorcaserin area under the curve (AUC) and body

weight in pediatric and adult subjects is consistent irrespective of the individual studies or 
age range of the study population. Irrespective of age, lorcaserin AUC values in the pediatric 
subjects with body weight of greater than 60 kg overlapped with the data observed from the 
studies involving adult subjects, suggesting a fixed dose approach similar to adults can be 
used for adolescent subjects with body weight greater than 60 kg.
In adolescent obese populations, it is anticipated that Belviq XR will result in similar effects.
As part of FDA postmarketing requirements, this study is designed to characterize the 
efficacy and safety of Belviq XR in adolescent obese populations in the United States.  It is 
also intended to support an indication for chronic weight management for obese adolescents 
ages 12 to 17 years old. 
7.1.2
Study Rationale
There is no specific FDA guidance for the approval of a weight loss product for adolescents.  
In adults, the Division’s 2007 draft Guidance for Industry Developing Products for Weight 
Management indicate that the product needs to satisfy either of the following mean or 
categorical criteria after 1 year of treatment:

The difference in mean weight loss between the active-product and placebo-treated 
groups is at least 5% and the difference is statistically significant.

The proportion of subjects who lose at least 5% of baseline body weight in the 
active-product group is at least 35%, is approximately double the proportion of 
subjects in the placebo-treated group who lose at least 5% of baseline body weight, 
and the difference between groups is statistically significant.
FDA awarded a weight management indication for Belviq based on Phase 3 study results 
which achieved the categorical criteria. In a Phase 3 study, a significantly greater proportion 
of subjects taking Belviq (47%) lost at least 5% of baseline body weight at 1 year as 
compared to subjects taking a placebo (23%).  It is anticipated that a similar effect will be 
demonstrated in obese adolescents, where weight loss will be assessed using BMI
measurements to account for growth. In this study, the objective is to demonstrate that BMI
reduction will be achieved during 52 weeks of treatment with Belviq XR 20 mg administered 
once daily (QD) compared to placebo in obese adolescents.
In the Phase 3 orlistat study in obese adolescents mentioned above, the proportion of subjects 
who lost at least 5% body weight is relatively low. At the end of the study at Week 52, only 
26.5% of the subjects achieved a 5% or greater BMI reduction compared to 15.7% in the 
placebo group. The placebo-corrected BMI reduction was about 0.86 kg/m2.  
There are limited trials for weight reduction in the adolescent population, ages 12 to 17 years
(Peirson, et al, 2015).  Thirty-one studies (29 behavioral, 2 pharmacological and behavioral) 
were included in a meta-analysis of randomized studies conducted in primary care centers in 
overweight and obese children and youth ages 2 to 18 years using behavioral (diet, exercise,
and lifestyle) and pharmacological interventions and providing 6-month postbaseline BMI or 
prevalence of overweight or obesity. Both interventions showed a significant effect on BMI

in favor of treatment (behavioral: 
standardized mean difference [SMD] -0.54, 
95% confidence interval [CI] -0.73, -0.36; orlistat plus behavioral: SMD -0.43, 95% CI -
0.60, -0.25). The studies reported no significant difference between groups in the likelihood 
of reduced prevalence of overweight or overweight and obese. A great deal of variation was 
noted across efficacious interventions.
In conclusion, this meta-analysis demonstrated
low-quality evidence that behavioral treatments alone are associated with a smaller effect in 
terms of reduced BMI compared with the effect shown by combined behavioral and
pharmacological interventions. This may be because the effect size in the randomized,
double blind, placebo controlled, phase 3 orlistat study in adolescents was relatively low and 
there was a lack of maintenance effect. These subjects started to regain their BMI after 
6 months of treatment. At end of the study, only 26.5% of subjects achieved a 5% or greater
BMI reduction compared to 15.7% in placebo group. In a sibutramine Phase 3 study in obese 
adolescents, a substantially higher proportion of subjects (69%) treated with sibutramine 
achieved at least a 5% BMI reduction compared to 21% of subjects in the placebo group. In 
addition, sibutramine resulted in a substantial reduction in mean BMI (between-group 
difference, 2.9 kg/m2) and mean weight (between-group difference, 8.4 kg) compared to 
placebo (Berkowitz, et al, 2006).  Unlike the weight loss effect of Belviq in adults and 
sibutramine in adolescents, subjects in the orlistat study started to increase their BMI after 
6 months of treatment.
In this study, it is assumed that treatment with Belviq XR 20 mg will lead to a BMI reduction
of more than 1 kg/m2, and a higher proportion of subjects will achieve more than a 5% and 
10% BMI reduction compared to placebo.  A between-group difference of 24% is the basis 
for the conservative assumption of a 20% effect size in the current study.
In addition, the total sample size of 360 subjects will be adequate to assess safety and 
exposure based on previous adolescent studies with weight management products (orlistat 
and sibutramine) (FDA, 2003; Chanoine, et al, 2005; Berkowitz, et al, 2006) and other 
metabolic or dyslipidemia medication products (ezetimibe, simvastatin) (FDA, 2007).

INVESTIGATIONAL PLAN
9.1
Overall Study Design and Plan
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in 
obese adolescents ages 12 to 17 years.  Approximately 360 subjects will be randomized in a 
1:1 ratio to Belviq XR 20 mg QD (180 subjects) and placebo (180 subjects).  Subjects will be 
stratified by sex.  Subjects will receive Belviq XR 20 mg or placebo QD in a 1:1 ratio for up 
to 52 weeks. Throughout the duration of the study, subjects will be encouraged to adhere to 
a lifestyle modification program that includes a standardized, age-appropriate diet and
exercise counseling (see Appendix 2).  
The study will consist of 2 phases:
Prerandomization and Randomization.  The 
Prerandomization Phase will last up to 30 days and consists of 1 visit during which subjects 
will be screened for eligibility.  The Randomization Phase consists of a Treatment Period and 
a Follow-Up Period.  The Treatment Period will last for a maximum of 52 weeks, with visits 
at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52; the Follow-Up Period will extend from the 
End of Treatment (EOT) visit to the End of Study (EOS) visit.
Subjects who screen fail can be re-screened only once after 60 days.  All subjects will 
continue in the study until the 52-week evaluation is completed.  Subjects who discontinue 
treatment prematurely will be followed up until study completion.
9.1.1
Prerandomization/Pretreatment Phase
Screening will occur during the Prerandomization Phase at Visit 1
9.1.1.1
Screening Period
The purpose of the Screening Period is to obtain the informed consent and assent and to 
establish protocol eligibility.  Procedures to be followed when obtaining informed consent 
are detailed in Section 5.3.  Careful initial screening is important in the recruitment of 
families who both fully understand the requirements of this 1 year, randomized, controlled 
trial and are truly interested in participation.  Interested caregivers and adolescents will be 
screened by phone to assess preliminary entry criteria.  Candidates will be given a brief 
description of the program and general study requirements, with an adolescent and a 
caregiver who is willing to participate.  If preliminary entry criteria are met, adolescents and 
their caregivers will be invited to an initial in-clinic meeting to further discuss the study.  A 
complete description of the study including assessments, the number of visits, the lifestyle 
program, the fact that the adolescent would be taking either the study drug or a placebo, the
duration of the study, and the necessity of having an adolescent wishing to participate as well 
as a participating caregiver will be described.  Consent and assent will be obtained and copies 
of the signed forms will be provided to families.  The importance of the study and its 
scientific merit will be discussed.  Ineligible adolescents will be referred to local weight 
management resources.  Screening period assessments and timing thereof are shown in 
Section 9.5.2.

Discussion of Study Design, Including Choice of Control Groups
The proposed dose and dosing frequency of Belviq XR in this study is 20 mg QD.  The PK 
parameters of a single 10-mg dose of Belviq were evaluated in healthy, adolescent obese 
subjects in Study APD356-025.  Overall, the PK parameters of Belviq and its main 
metabolites, M1 and M5, were similar to those in adults.  Following a single, oral 
administration of Belviq 10 mg to a total of 8 healthy adolescent (ages 12 to 17 years old) 
obese subjects, the mean maximum concentration observed and the area under the 
concentration-time curve from time zero to infinity (AUC(0-inf)) were 36.5 ng/mL and 
464 hr×ng/mL, respectively.  The mean Belviq terminal phase half-life was 9.70 hours, 
similar to that observed in adults, thus supporting a similar dosing frequency (QD) in 
adolescent subjects.
Additionally, a single dose PK study in 8 healthy obese pediatric subjects ages 6 to 11 years 
of age was performed. The PK analysis after a single 10-mg dose of lorcaserin revealed that 
the lorcaserin AUC(0-inf) values tended to increase with decreasing body weight and age.
However, the body weight normalized AUC(0-inf) values were similar across the age groups, 
therefore the data indicated no effect of age on the lorcaserin PK. Integrated assessment of 
the PK versus body weight relationship, pooling the data from pediatric and adult subjects 
from previous studies, suggested that the lorcaserin area under the curve values for subjects 
with body weight of at least 60 kg overlapped with the area under the curve values from 
adolescents and adults. Therefore, no dose adjustment relative to adults and adolescents is 
deemed necessary for pediatric or adolescent subjects with a body weight of at least 60 kg.
Based on CDC growth charts, the likelihood of subjects who are older than 12 years of age 
having a body weight of less than 60 kg is very low; therefore, the current study as designed 
to enroll subjects between 12 to 17 years of age with body weight at least 60 kg, will cover
majority of the population of interest.  The targeted study population comprises 360 obese 
adolescents 12 to 17 years of age, with a body weight at least 60 kg.
Obese adolescents will be identified using gender- and age-specific BMI measurement.  
Obesity in adolescents is defined by US Expert committee recommendations as BMI in or 
above the 95th percentile (Barlow, 2007).

Randomization will be used in this study to avoid bias in the assignment of subjects to 
treatment, to increase the likelihood that known and unknown subject attributes 
(eg, demographics, baseline characteristics) are balanced across treatment groups, and to 
ensure the validity of statistical comparisons across treatment groups.  Blinding to treatment 
will be used to reduce potential bias during data collection and evaluation of endpoints.
9.3
Selection of Study Population
Approximately 700 subjects will be screened to ensure that 360 subjects will be randomized.
Subjects who do not meet all inclusion criteria or do meet any exclusion criteria will not be 
eligible to receive study drug. Subjects who screen fail can be re-screened only once after 
60 days.
9.3.1
Inclusion Criteria
Subjects must meet all of the following criteria to be included in this study:
1. Healthy male or female adolescents, ages 12 to 17 years old at Screening, with a BMI 
that is greater than or equal to the United States (US)-weighted mean of the 
95th percentile based on age and sex with a body weight greater than 60 kg
2. Subjects and their families are not planning to move away from the area for the 
duration of the study
3. Subjects able and willing to comply with all aspects of the study, including a 
standardized, reduced-calorie diet and an age-appropriate, increased physical activity 
program
4. Subjects considered in stable health in the opinion of the investigator
5. Caregivers or guardians meet the following requirements:
a.
Able and willing to support and supervise study participation in the opinion of the 
investigator, including consideration of any existing physical, medical, or mental 
condition that prevents compliance with the protocol
b. Able and willing to personally comply with and execute all aspects of the study 
requirements for the caregivers or guardians
9.3.2
Exclusion Criteria
Subjects who meet any of the following criteria will be excluded from this study:
1. Clinically significant new illness within 1 month before randomization that may 
affect the subject’s ability to fulfill the study requirements or significantly confound 
the assessments
2. Subjects who cannot swallow investigational products
3. Any of the following findings on screening echocardiography:

Aortic regurgitation mild or greater


Mitral regurgitation moderate or greater

Mitral or aortic valve stenosis greater than mild (ie, aortic stenosis [AS]: 
jet >3.0 m/s, mean gradient >25 mm Hg, and aortic valve area [AVA] 
<1.5 cm2; MS: mean gradient >5 mm Hg and mitral valve area [MVA]


Systolic pulmonary artery pressure (SPAP) >40 mm Hg (and/or tricuspid 
regurgitation (TR) jet velocity >2.9 m/s)
-
In cases where an actual SPAP value is not measurable due to lack of 
adequate TR jet, the pulmonary flow acceleration time measured at the 
right ventricular outflow tract (RVOTAT), will be used to assess 
eligibility. Patients with a RVOTAT ≤100 msec will be excluded, 
suggesting an elevated mean SPAP; eligibility for the those patients with 
RVOTAT between 100 and 120 msec will be determined based on 
combined assessment of the TR jet, septal motion and right ventricular 
size.

Left ventricular ejection fraction <45%

Intracardiac mass, tumor or thrombus

thermometric values over a specific time period can be recorded and retrieved as required.
9.4.3
Method of Assigning Subjects to Treatment Groups
Subjects will be assigned to treatments based on a computer-generated randomization 
scheme that will be reviewed and approved by an independent statistician.  The 
randomization scheme and identification for each subject will be included in the final clinical 
study report for this study.
Subjects will be centrally stratified by sex (male and female).  Within each stratum, subjects 
will be randomized to receive either Belviq XR 20 mg or placebo QD in a 1:1 ratio.  
Randomization will be performed centrally by an interactive voice or web response system 
(IxRS).  The IxRS or clinical supply vendor will generate the randomized identification
numbers to be included on study packaging.  Upon signature of the ICF, the investigator or 
designee will access the IxRS to register the subject information.  At Randomization, the 
IxRS will assign each subject a unique randomization number.  At each subsequent visit 
during the Treatment Period and Follow-Up Period, the investigator or designee will access 
IxRS to obtain dispensing information and to register the subject’s visit.
9.4.4
Selection and Timing of Dose for Each Subject
Subjects should take the study medication once daily at approximately the same time of 
every day, and be encouraged to take the study medication with an adequate amount of water 
(8 oz. or 240 mL).
9.4.5
Blinding
During the Randomization Phase, subjects and all personnel involved with the conduct and 
interpretation of the study, including investigators, site personnel, and sponsor staff will be 
blinded to the treatment codes.  Randomization data will be kept strictly confidential, filed 
securely by an appropriate group with the sponsor or CRO, and accessible only to authorized 
persons (eg, Eisai Global Safety) until the time of unblinding, per the SOP.
A master list of all treatments and the subject numbers associated with them will be 
maintained in a sealed envelope by the clinical supply vendor, the IxRS vendor, and the 
sponsor.  In the event that emergency conditions require knowledge of the study treatment 
given, the blind may be broken via the code breaker facility within the IxRS.  Emergency 
procedures for revealing drug codes are given in Section 9.5.4.5.  If possible, before breaking 
the blind, the investigator should consult with the sponsor or designee to ascertain the 
necessity of breaking the code.

Echocardiographic assessments will be used to exclude subjects with FDA-defined 
valvulopathy, pulmonary hypertension, and other major cardiovascular disease (as outlined in 
Exclusion Criterion No. 3) during the Screening Period.  Additionally, cardiac valvular 
function and pulmonary systolic pressure changes at Weeks 28 and 52 will be assessed.  
Valvular regurgitation as assessed in the echocardiogram will be rated absent, trace, mild, 
moderate, or severe for the aortic, mitral, and tricuspid valves; the rating will be absent or 
present for the pulmonic valve. The evaluations will be based on guidelines from the 
American Society of Echocardiography. Pulmonary artery pressure will be estimated from 
the tricuspid regurgitant jet velocity.
9.5.1.5.1
ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered an investigational product.  An AE does not necessarily have a causal 
relationship with the medicinal product.  For this study, the study drug is Belviq XR
(lorcaserin hydrochloride).
The criteria for identifying AEs in this study are:
•
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or 
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE)
•
Any new disease or exacerbation of an existing disease 
•
Any deterioration in non-protocol-required measurements of a laboratory value or other 
clinical test (eg, ECG, x-ray) that results in symptoms, a change in treatment, or 
discontinuation of study drug
•
Recurrence of an intermittent medical condition (eg, headache) not present pretreatment 
(Baseline)
•
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of study drug, or withholding 
of study drug, whether prescribed in the protocol or not.
All AEs observed during the study will be reported on the Adverse Event CRF.  All AEs,
regardless of relationship to study drug or procedure, should be collected beginning from the 
time the subject signs the study ICF through the last visit in the Treatment Phase.  Subjects 
who fail screening primarily due to AE(s) must have the AE(s) leading to screen failure 
reported on the Screening Disposition CRF.  SAEs will be collected for 28 days after the last 
dose.
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute 
an AE.  Medical and scientific judgment should be exercised in deciding whether an isolated

Clinical Study Protocol
APD356-A001-403
Eisai
FINAL (v4.0):  03 Nov 2016
Confidential
Page 44 of 81
laboratory abnormality should be classified as an AE.  Any laboratory abnormality 
considered to constitute an AE should be reported on the Adverse Event CRF. 
Abnormal ECG (corrected QT interval [QTc]) results, if not otherwise considered part of a 
clinical symptom that is being reported as an AE, should be considered an AE if the QTc 
interval is greater than 450 msec and there is an increase of more than 60 msec from baseline.  
Any ECG abnormality that the investigator considers as an AE should be reported as such.
It is the responsibility of the investigator to review the results of the C-SSRS, PHQ-9, and 
WRAML-2 in all subjects and determine if any result constitutes an AE.  Medical and 
scientific judgment should be exercised in deciding whether an isolated suicidality rating 
scale response should be classified as an AE (see Section 9.5.1.5.9 for a description of the 
C-SSRS).
All AEs must be followed for 28 days after the subject’s last dose or until resolution, 
whichever comes first.  All SAEs must be followed to resolution or, if resolution is unlikely, 
to stabilization.
Every effort must be made by the investigator to categorize each AE according to its 
severity and its relationship to the study treatment.
Assessing Severity of Adverse Events
Adverse events will be graded on a 3-point scale (mild, moderate, severe) and reported in the 
detail indicated on the CRF.  The definitions are as follows:
Mild
Discomfort noticed, but no disruption of normal daily activity
Moderate Discomfort sufficient to reduce or affect normal daily activity
Severe
Incapacitating, with inability to work or to perform normal daily activity
The criteria for assessing severity are different than those used for seriousness (see
Section 9.5.1.5.2 for the definition of an SAE).
Assessing Relationship to Study Treatment
Items to be considered when assessing the relationship of an AE to the study treatment are:
•
Temporal relationship of the onset of the event to the initiation of the study treatment
•
The course of the event, especially the effect of discontinuation of study treatment or 
reintroduction of study treatment, as applicable
•
Whether the event is known to be associated with the study treatment or with other 
similar treatments
•
The presence of risk factors in the study subject known to increase the occurrence of 
the event

•
The presence of nonstudy, treatment-related factors that are known to be associated 
with the occurrence of the event
Classification of Causality
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question:
Is there a reasonable possibility that the study drug caused the AE?
Yes (related)
A causal relationship between the study drug and the AE is a reasonable 
possibility.
No (not related) A causal relationship between the study drug and the AE is not a 
reasonable possibility.
9.5.1.5.2
SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An SAE is any untoward medical occurrence that at any dose:
•
Results in death
•
Is life-threatening (ie, the subject was at immediate risk of death from the AE as it 
occurred; this does not include an event that, had it occurred in a more severe form or 
was allowed to continue, might have caused death)
•
Requires inpatient hospitalization or prolongation of existing hospitalization
•
Results in persistent or significant disability/incapacity
•
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug)
Other important medical events that may not be immediately life-threatening or result in 
death or hospitalization but, when based on appropriate medical judgment, may jeopardize 
the subject or may require intervention to prevent one of the outcomes in the definition of 
SAE listed above should also be considered SAEs.  Medical and scientific judgment should 
be exercised in deciding whether expedited reporting is appropriate in such situations. 
For this study, the following events should always be considered serious and reported as an 
important medical event if it does not meet other serious criteria:
•
Serotonin syndrome (must have at least 1 of the following: Spontaneous clonus; 
Inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus)
•
Psychosis
•
Suicidal behavior

•
Priapism
•
New onset valvular heart disease
•
New onset pulmonary hypertension
•
Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas 
of the skin
•
Fibroadenomas of the breast or ductal carcinoma in situ
The following additional study specific AE of interest should be reported using the 
procedures detailed in Reporting of SAEs (Section 9.5.4.1), even if the study specific event 
does not meet serious criteria.  If the event meets seriousness criteria, it should be reported as 
an SAE as above.  However, if the event listed below does not meet serious criteria, it should 
be noted as nonserious on the Adverse Event CRF:  

Suicidal ideation   

Euphoria 
In addition to the above, events associated with special situations include pregnancy or 
exposure to study drug through breastfeeding; AEs associated with study drug overdose, 
misuse, abuse, or medication error.  These events associated with special situations are to be 
captured using the SAE procedures but are to be considered as SAEs only if they meet 1 of 
the above criteria.  All AEs associated with special situations are to be reported on the CRF 
whether or not they meet the criteria for SAEs.  
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization.
The following hospitalizations are not considered to be SAEs because there is no “AE” (ie, 
there is no untoward medical occurrence) associated with the hospitalization:
•
Hospitalizations for respite care
•
Planned hospitalizations required by the protocol  
•
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed after study drug administration)
•
Hospitalization for administration of study drug or insertion of access for 
administration of study drug
•
Hospitalization for routine maintenance of a device (eg, battery replacement) that was 
in place before study entry

VITAL SIGNS AND WEIGHT MEASUREMENTS
Vital sign measurements (ie, systolic and diastolic BP [mmHg], pulse [beats per minute], 
respiratory rate [per minute], body temperature [in centigrade]), and weight (kg) will be 
obtained as designated in the Schedule of Procedures/Assessments (Table 2) by a validated 
method.  BP and pulse will be measured after the subject has been sitting for 5 minutes.  All 
BP measurements should be performed on the same arm, preferably by the same person. 
When vital signs are to be obtained concurrently with PK or other blood samples, the vital 
sign measurements will be performed before drawing blood samples in order to maximize the 
accuracy of blood sampling times while minimizing the potential effects of blood drawing on 
recordings obtained during safety assessments.
9.5.1.5.5
HEIGHT MEASUREMENTS
Height (cm) measurements will be obtained as designated in the Schedule of 
Procedures/Assessments (Table 2).

OTHER SAFETY ASSESSMENTS
WRAML-2
The WRAML-2 administration will consist of the Core Battery, which provides scores on 
Verbal Memory, Visual Memory, and Attention/Concentration.  There are 6 subtests (2 for 
each area).
The tests provide standardized scores based on age and gender, and are 
appropriate for ages 5 to 90 years.  The WRAML-2 will be used to assess lorcaserin effects 
on cognitive function. In addition, signs and symptoms of cognitive related AEs, including 
impairments in attention, memory, and adverse effects on schoolwork will be captured in the 
eCRF.
PHQ-9
The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and 
measuring the severity of depression:

The PHQ-9 incorporates Diagnostic and Statistical Manual of Mental Disorders, 4th 
Edition (DSM-IV) depression diagnostic criteria with other leading major depressive 
symptoms into a brief self-report tool.

The tool rates the frequency of the symptoms which factors into the scoring severity 
index.

Question 9 on the PHQ-9 screens for the presence and duration of suicide ideation.

A follow-up, non-scored question on the PHQ-9 assigns weight to the degree to 
which depressive problems have affected the patient's level of function. 
C-SSRS
The C-SSRS collects information pertinent to suicidal ideation and actions.  It consists of a 
Baseline version which will be administered at baseline and a Since Last Visit version which 
will be administered at the remaining visits.  C-SSRS will be used to assess signal of 
depression and suicidal ideation or behavior. It will be performed at Baseline and at study 
visits as designated in the Schedule of Procedures/Assessments (Table 2).
Signs and symptoms of priapism (painful erection) and hyperprolactinemia (menstrual cycle 
abnormalities or galactorrhea) will be captured in the eCRF.
Hand X-Ray will be evaluated for any potential negative effect on bone age as designated in 
the Schedules/Assessments (Table 2). 
Neuromuscular sign assessment for serotonin 
syndrome will be performed as designated in the Schedule of Procedures/Assessments 
(Table 2) to screen for potential serotonergic syndrome components. 
Serotonergic 
syndromes that meet the diagnostic criteria will be captured by AE eCRF.

Reporting of Serious Adverse Events, Pregnancy, and Events Associated 
with Special Situations
9.5.4.1
Reporting of Serious Adverse Events
All SAEs, regardless of their relationship to study treatment, must be reported on a 
completed SAE form by email or fax as soon as possible but no later than 1 business 
day from the date the investigator becomes aware of the event.
SAEs, regardless of causality assessment, must be collected through the through the last visit
and for 28 days after the subject’s last dose.  All SAEs must be followed to resolution or, if 
resolution is unlikely, to stabilization.  Any SAE judged by the investigator to be related to 
the study treatment or any protocol-required procedure should be reported to the sponsor 
regardless of the length of time that has passed since study completion.
The detailed contact information for reporting of SAEs is provided in the Investigator Study 
File.
For urgent safety issues, please ensure all appropriate medical care is administered to the 
subject and contact the appropriate study team member listed in the Investigator Study File.
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report.  This includes the investigator’s assessment of causality.
Any follow-up information received on SAEs should be forwarded within 1 business day of 
its receipt.  If the follow-up information changes the investigator’s assessment of causality, 
this should also be noted on the follow-up SAE form.
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested by 
the sponsor.
The investigator must notify his/her IRB/IEC of the occurrence of the SAE, in writing, if 
required by their institution.  A copy of this communication must be forwarded to the sponsor 
to be filed in the sponsor’s Trial Master File.
9.5.4.2
Reporting of Pregnancy and Exposure to Study Drug through Breastfeeding
Any pregnancy in which the estimated date of conception is either before the last visit or 
within 28 days of last study treatment or any exposure to study drug through breastfeeding 
during study treatment or within 28 days of last study treatment must be reported.
If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, this 
should be reported regardless of the length of time that has passed since the exposure to study 
treatment.

A congenital anomaly, death during perinatal period, an induced abortion, or a spontaneous 
abortion are considered to be an SAE and should be reported in the same time frame and in 
the same format as all other SAEs (see Section 9.5.4.1).
Pregnancies or exposure to study drug through breastfeeding must be reported by fax or 
email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy.  The contact information for the reporting of pregnancies 
and exposure to study drug through breastfeeding is provided in the Investigator Study File.  
The Pregnancy Report Form must be used for reporting.  All pregnancies must be followed to 
outcome.  The outcome of the pregnancy must be reported as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the outcome.
A subject who becomes pregnant must be withdrawn from the study. 
9.5.4.3
Reporting of Events Association with Special Situations
9.5.4.3.1
REPORTING OF ADVERSE EVENTS ASSOCIATED WITH STUDY DRUG OVERDOSE,
MISUSE, ABUSE, OR MEDICATION ERROR
Adverse events associated with study drug overdose, misuse, abuse, and medication error 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication error are defined as follows:
Overdose
Accidental or intentional use of the study drug in an amount higher
than the protocol-defined dose
Misuse
Intentional and inappropriate use of study drug not in accordance with 
the protocol or authorized dose, route of administration, or 
indication(s) or use of prescription-only study drug without a 
prescription

Sporadic or persistent intentional excessive use of study drug 
accompanied by harmful physical or psychological effects
Medication error
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of the 
healthcare professional, subject, or consumer.  Such events may be 
related to professional practice, healthcare products, occupational 
exposure, procedures, or
systems,
including prescribing,
order 
communication,
product
labeling, 
packaging, 
nomenclature,
compounding,
dispensing,
distribution,
administration,
education,
monitoring, or use.
All AEs associated with overdose, misuse, abuse, or medication error should be captured on 
the Adverse Event CRF and also reported using the procedures detailed in Section 9.5.4.1
even if the AEs do not meet serious criteria.  Abuse is always to be captured as an AE.  If the

AE associated with an overdose, misuse, abuse, or medication error does not meet serious 
criteria, it must still be reported using the SAE form and in an expedited manner but should 
be noted as nonserious on the SAE form and the Adverse Event CRF.
9.5.4.3.2
REPORTING OF STUDY-SPECIFIC EVENTS
Study-specific events (listed below) should always be considered as serious important 
medical events and be entered on the Adverse Event CRF and reported using the procedures 
detailed in Reporting of Serious Adverse Events (Section 9.5.4.1), even if the study-specific 
event does not meet other serious criteria.  

Serotonin syndrome
Must have at least 1 of the following: spontaneous clonus; 
inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus

Psychosis

Suicidal behavior 

Priapism

New onset of valvular heart disease

New onset pulmonary hypertension

Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas 
of the skin

Fibroadenomas of the breast or ductal carcinoma in situ
The following additional study specific AE of interest should be reported using the 
procedures detailed in Reporting of SAEs (Section 9.5.4.1), even if the study-specific 
event does not meet serious criteria.  If the event meets seriousness criteria, it should 
be reported as an SAE as above.  However, if the event listed below does not meet 
serious criteria, it should be noted as nonserious on the Adverse Event CRF:  

Suicidal ideation

Euphoria 
9.5.4.4
Expedited Reporting
The sponsor must inform investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (ie, within 
specific time frames).  For this reason, it is imperative that sites provide complete SAE 
information in the manner described above.
9.5.4.5
Breaking the Blind
In the case of a medical emergency where the appropriate treatment of the subject requires 
knowledge of the study treatment given, the investigator may break the randomization code

for an individual subject.  In all such cases, the AE necessitating the emergency blind break 
will be handled as an SAE in accordance with the procedures indicated above.  Any broken 
code will be clearly justified and documented.  The medical monitor must be notified 
immediately of the blind break.
9.5.4.6
Regulatory Reporting of Adverse Events
Adverse events will be reported by the sponsor or a third party acting on behalf of the 
sponsor to regulatory authorities in compliance with local and regional law and established 
guidance.  The format of these reports will be dictated by the local and regional 
requirements.
9.5.5
Completion/Discontinuation of Subjects
The investigator may withdraw the subject from the study at any time for safety or 
administrative reasons.  A subject may elect to discontinue the study at any time for any 
reason.  All subjects will continue in the study until the 52-week evaluation is completed.  
Subjects who discontinue treatment prematurely will be followed up until study completion.  
All subjects who discontinue the study are to complete the study’s early discontinuation 
procedures indicated in the Schedule of Procedures/Assessments (Table 2).
The investigator will promptly explain to the subject involved that the study will be 
discontinued for that subject and provide appropriate medical treatment and other necessary 
measures for the subject.  A subject who has ceased to return for visits will be followed up by 
mail, phone, or other means to gather information such as the reason for failure to return, the 
status of treatment compliance, the presence or absence of AEs, and clinical courses of signs 
and symptoms.
Subjects who discontinue early from the study will be discontinued for 1 of these primary 
reasons: AE(s), lost to follow-up, subject choice, withdrawal of consent, pregnancy, study 
terminated by sponsor, or other.  In addition to the primary reason, the subject may indicate
1 or more of secondary reasons for discontinuation.  Study disposition information will be 
collected on the Subject Disposition CRF.
Detailed retention strategies will be developed and included in study manual. These include 
a highly trained and competent staff, easy access to the clinic, reminder and follow-up calls, 
interactive group sessions with games and hands-on nutrition and physical activity 
demonstrations, random raffle drawings, social events, birthday and holiday cards, and
newsletters. In addition, home visits for assessments of families will be an option, as needed, 
to maximize data collection. This detailed retention plan will help prevent missing data.
A subject removed from the study for any reason may not be replaced.
9.5.6
Abuse or Diversion of Study Drug
During the study, the investigator will report any concern about abuse or diversion of study 
drugs by completing the Abuse or Diversion of Study Drug CRF.  The DEA Registrant has

the responsibility to comply with local, state, and Federal laws to notify the Field Division 
Office of the DEA of any theft or significant loss of any controlled substances upon 
discovery of such theft or loss.
9.5.7
Confirmation of Medical Care by Another Physician
The investigator will instruct subjects to inform site personnel when they are planning to 
receive medical care by another physician.  At each visit, the investigator will ask the subject 
whether he or she has received medical care by another physician since the last visit or is 
planning to do so in the future.  When the subject is going to receive medical care by another 
physician, the investigator, with the consent of the subject, will inform the other physician 
that the subject is participating in the clinical study.
9.6
Data Quality Assurance
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines.  Site audits 
will be made periodically by the sponsor’s or the CRO’s qualified compliance auditing team, 
which is an independent function from the study team responsible for conduct of the study.
9.6.1
Data Collection
Data required by the protocol will be collected on the CRFs and entered into a validated data 
management system that is compliant with all regulatory requirements.  As defined by ICH 
guidelines, the CRF is a printed, optical, or electronic document designed to record all of the 
protocol-required information to be reported to the sponsor on each study subject.
Data collection on the CRF must follow the instructions described in the CRF Completion 
Guidelines.  The investigator has ultimate responsibility for the collection and reporting of all 
clinical data entered on the CRF.  The investigator or designee as identified on Form 
FDA 1572 must sign the completed CRF to attest to its accuracy, authenticity, and 
completeness.
Completed, original CRFs are the sole property of Eisai and should not be made available in 
any form to third parties without written permission from Eisai, except for authorized 
representatives of Eisai or appropriate regulatory authorities.
9.6.2
Clinical Data Management
All software applications used in the collection of data will be properly validated following 
standard computer system validation that is compliant with all regulatory requirements.  All 
data, both CRF and external data (eg, laboratory data), will be entered into a clinical system.

Demographic and Other Baseline Characteristics
Demographic and other baseline characteristics for the FAS and Safety Analysis Sets will be 
summarized for each treatment group using descriptive statistics or frequency count.  
Continuous demographic and baseline variables include age, height, BMI, waist 
circumference, and weight; categorical variables include sex and race.
9.7.1.5

All investigator terms for medications recorded in the CRF will be coded to an 11-digit 
character code using the World Health Organization Drug Dictionary.  The number 
(percentage) of subjects who took prior and concomitant medications will be summarized for
the Safety Analysis Set by treatment group, Anatomical Therapeutic Chemical class, and 
World Health Organization Drug Dictionary preferred term (PT).  Prior medications will be 
defined as medications that stopped before the first dose of study drug.  Concomitant 
medications will be defined as medications that started on or after the date of the dosing of 
study drug and continued up to 30 days afterward.
9.7.1.6
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, while the PP will 
be used as a supportive analysis.  Unless specified otherwise, a 2-sided α=0.05 significance 
level will be used for all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change 
from baseline in BMI will be analyzed using the repeated measures analysis of covariance 
model (ANCOVA) with factors of treatment, visits (Baseline, Week 1, 5, 8, 12, 20, 28, 36, 
44, and 52), sex (male and female), treatment-by-visit interaction as fixed effect, subjects as 
random effect, and the baseline age and BMI as covariates.  The missing values will be 
imputed using a pattern mixture model utilizing multiple imputation (MI) using the same 
model as the analysis model.  The missing values will be imputed for a visit at a time using 
the complete cases up to and include the current visit for a particular visit.  The unstructured 
covariance matrix will be used in the analysis and the treatment comparison at Week 52 will 
be the event of interest.  In case of a convergence issue, the Toeplitz covariance structure will 
be used in the model.  As a sensitivity analysis, the missing values will also be imputed using 
pattern mixture MI method assuming the missing value is missing not at random (MNAR). 
The details of the analysis model and missing value imputation method will be further 
described in the SAP.
In addition, the following analyses will also be considered as sensitivity analyses:

PP analysis: The same primary efficacy analyses described above will be repeated 
based on the PP.

Change from baseline in standardized BMI score (Z-score):
The same primary 
efficacy analyses described above will be repeated using Z-score.

Subgroup analyses and additional sensitivity analyses, if appropriate, may also be performed 
and will be described in the SAP.  
Key Secondary Efficacy Analysis
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 
5% BMI reduction at Week 52.  The secondary efficacy endpoint will be analyzed only if the 
test for the primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be 
analyzed using a logistic regression model with factors of treatment, and sex (male and 
female), and baseline BMI as a covariate using FAS.  Subjects with any missing assessment 
at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be 
analyzed using mixed effect model repeated measurement analysis (MMRM) and categorical
variables will be analyzed using the Cochran Mantel Haenszel test, Chi-square test, or 
logistic regression as appropriate.  Additional analysis may be performed as needed using 
appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including sex (male 
and female), race (white, black, Asian, and other). Additional subgroups may be explored, if 
deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and 
sensitivity analyses.
9.7.1.7
Pharmacokinetic, Pharmacodynamic, Pharmacogenomic, and Other Biomarker
Analyses
9.7.1.7.1
PHARMACOKINETIC ANALYSES
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling.  The effect of covariates, such as baseline characteristics
or demographics, on PK will be explored.  Derived exposure parameters such as the 
maximum observed concentration and the area under the concentration-time curve from time
0 to 24 hours at steady-state will be calculated from the final PK model using individual 
posterior estimates of the PK parameters and from dosing history.  The PK analysis set will 
be used for this analysis.
9.7.1.7.2
PHARMACODYNAMIC ANALYSES
Change from Baseline in BMI will be assessed as the PD analysis.  The PD analysis set will 
be used for this analysis.

Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% 
and ≥10% BMI reduction, and change in waist circumference from baseline) will also be 
assessed as part of the PD analysis.  The PK/PD analysis set will be used for this analysis.
9.7.1.7.3
PHARMACOKINETIC/PHARMACODYNAMIC ANALYSES
Population PK/PD modeling will be used to explore the relationship between lorcaserin 
plasma exposure and response, including but not limited to change in BMI from baseline and 
the probability of achieving at least a 5% and at least a 10% change in BMI from baseline to 
Week 52.  Additionally, exposure-safety relationships for select safety parameters may be 
explored graphically, depending on the data at the end of study.  Any emergent relationship 
may be modeled as appropriate.  Any parameters based on the study data may be considered 
for exploratory assessment for its relationship to PK.
9.7.1.7.4
PHARMACOGENOMIC AND PHARMACOGENETIC ANALYSES
Not applicable
9.7.1.8
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments 
including the incidence of AEs (including changes from baseline in physical examination), 
growth (CDC growth chart and bone age determined by x-ray of the hand), sexual maturation 
(Tanner Staging), out-of-normal-range laboratory safety test values, change from baseline in 
laboratory safety test values, ECGs, and vital sign measurements will be summarized by 
treatment group using descriptive statistics or frequency count as appropriate.  In addition, 
cognitive function will be evaluated by the WRAML-2, depression will be evaluated by the 
PHQ-9, and suicidal ideation and behavior will be evaluated by the C-SSRS, and will also be 
summarized by treatment group using descriptive statistics or frequency count as appropriate.  
All WRAML-2 raw scores from the Core Battery will be converted to age and gender 
standard scores for purposes of intra individual comparisons.  For echocardiographic 
assessments, the proportion of subjects who develop FDA-defined valvulopathy, the 
proportion of subjects who develop pulmonary hypertension [pulmonary hypertension is 
defined when the subject’s systolic pulmonary artery pressure (SPAP) ≥40 mmHg evaluated 
by echocardiograph], and change from baseline in SPAP will be summarized by treatment 
group at Week 28 and Week 52 using descriptive statistics or frequency count as appropriate.
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
9.7.1.8.1
EXTENT OF EXPOSURE
Subjects will receive Belviq XR 20 mg or placebo QD for up to 52 weeks. The extent of 
exposure will be characterized by duration of exposure (in weeks) for each treatment group.

Duration of exposure will be defined as the number of weeks between the date the subject 
received the 1st dose of study drug and the date the subject received the last dose of study 
drug.  Duration of exposure will be summarized using descriptive statistics by treatment 
group.  In addition, the duration of exposure will be categorized and will be summarized 
using frequency count by treatment group.
9.7.1.8.2
ADVERSE EVENTS
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities 
(MedDRA).  Adverse events will be coded to the MedDRA (Version 18.0 or higher) lower 
level term closest to the verbatim term.  The linked MedDRA PT and primary system organ 
class (SOC) are also captured in the database.
A treatment-emergent AE (TEAE) is defined as an AE that emerges during treatment (up to 
28 days after the last dose of study drug), having been absent at pretreatment (Baseline) or 
•
Reemerges during treatment (up to 28 days after the last dose of study drug), having been 
present at pretreatment (Baseline) but stopped before treatment, or 
•
Worsens in severity during treatment relative to the pretreatment state, when the AE is 
continuous.
Only those AEs that were treatment emergent will be included in summary tables.  All AEs, 
treatment emergent or otherwise, will be presented in subject data listings.
The TEAEs will be summarized by treatment group.  The following summaries will be 
reported for TEAES:

Incidence of TEAEs in descending order of frequency

Incidence of TEAEs by SOC and PT

Incidence of treatment-related TEAEs by SOC and PT

Incidence of TEAEs by SOC, PT and maximum severity (mild, moderate, or severe)

Incidence of treatment-related TEAEs by SOC, PT, and maximum severity (mild, 
moderate, or severe)

Incidence of TEAEs by SOC, PT, and relationship to study drug (Yes [related] or No 
[not related])
A subject will be counted only once within a SOC or PT, if the subject experienced more 
than 1 TEAE within a specified SOC and PT.

In addition, subjects with TEAEs leading to discontinuation from study drug and AEs of 
special interest as described in Section 9.5.4.3.2 will be summarized by MedDRA SOC and 
PT for each treatment group. 
9.7.1.8.3
LABORATORY VALUES
Laboratory results will be summarized using Système International units, as appropriate.  For 
all quantitative parameters listed in Section 9.5.1.5.3, the actual value and the change from 
baseline to each postbaseline visit and to the end of treatment (defined as the last 
on-treatment value) will be summarized by visit and treatment group using descriptive 
statistics.  Percentages will be based on the number of subjects with both nonmissing 
baseline and relevant postbaseline results.
Laboratory test results will be assigned a low/normal/high (LNH) classification according to 
whether the value was below (L), within (N), or above (H) the laboratory parameter’s 
reference range.  Within-treatment comparisons for each laboratory parameter will be based 
on 3-by-3 tables (shift tables) that compare the baseline LNH classification to the LNH 
classification at the End of Treatment and the Follow-Up visits.  Similar shift tables will also 
compare the baseline LNH classification to the LNH classification for the highest and lowest 
value during the treatment period.
Appendix 1
presents the criteria that will be used to identify subjects with 
treatment-emergent markedly abnormal laboratory values (TEMAV).  Except for phosphate, 
a TEMAV is defined as a postbaseline value with an increase from baseline to a grade of 2 or 
higher.  For phosphate, a TEMAV was defined as a postbaseline value with an increase from 
baseline to a grade of 3 or higher.  When displaying the incidence of TEMAVs, each subject 
may be counted once in the laboratory parameter high and in the laboratory parameter low 
categories, as applicable.
9.7.1.8.4
VITAL SIGNS
Descriptive statistics for vital signs parameters (eg, systolic and diastolic BP, pulse, 
respiratory rate, temperature, weight) and changes from baseline will be presented by visit
and treatment group.

ELECTROCARDIOGRAMS
For each ECG parameter (including PR interval, RR interval, QRS interval, QT interval, QTc
interval (Bazett formula), QTc interval (Fridericia formula), and heart rate), the actual value 
and change from baseline will be summarized by visit and treatment group using descriptive 
statistics. 
Shift tables will present changes from baseline in ECG interpretation (categorized as normal; 
abnormal, not clinically significant; and abnormal, clinically significant) to end of treatment. 
Maximum postbaseline QTc (Bazett) and QTc (Fridericia) will also be tabulated by treatment 
group as follows:

Number (percentage) of subjects in greater than 450 msec, greater than 480 msec, and 
greater than 500 msec during the treatment, and

Number (percentage) of subjects with an increment of greater than 30 msec and 
greater than 60 msec from the baseline visit.
9.7.1.8.6
OTHER SAFETY ANALYSES
Other safety assessments including adolescent growth evaluations using 95th percentile CDC 
growth charts and bone age using x-ray of the hand, sexual maturation as measured in Tanner 
Staging, neuromuscular sign assessment for serotonin syndrome, signs and symptoms of 
priapism and prolactinemia, study drug effect on cognitive function assessed by WRAML-2, 
assessment of suicidality using C-SSRS, and depression assessment using PHQ-9 will be 
summarized by treatment group at each scheduled visit.  For echocardiographic assessments, 
the proportion of subjects who develop FDA-defined valvulopathy, the proportion of subjects 
who develop pulmonary hypertension (defined as when a subject’s SPAP is ≥40 mmHg 
evaluated by echocardiograph], and change from baseline in SPAP will also be summarized 
by treatment group at Week 28 and Week 52.
9.7.2
Determination of Sample Size
The proposed sample size is based on the comparison of the primary efficacy endpoint, 
change from Baseline in BMI at Week 52 between the Belviq XR 20-mg treatment group and 
placebo group.  Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 
360 subjects in a 1:1 ratio (n=180 in the Belviq XR 20-mg treatment group; n=180 in the 
placebo group) will have at least 90% power to detect a treatment difference of 1 kg/m2 in 
BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at 
least a 5% BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, 
this sample of 360 subjects (180 subjects for Belviq XR 20 mg and 180 subjects for placebo) 
will also have greater than 85% power to detect an absolute difference of 20% between the 
Belviq XR 20-mg group and placebo group, using a 2-sided Fisher’s Exact test with α=0.05.  
The assumption used in the sample size calculation is based on the 2 pivotal lorcaserin 
studies, APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

11 PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE 
PROCEDURES)
11.1
Changes to the Protocol
Any change to the protocol requires a written protocol amendment or administrative change 
that must be approved by the sponsor before implementation.  Amendments specifically 
affecting the safety of subjects, the scope of the investigation, or the scientific quality of the 
study require submission to health or regulatory authorities as well as additional approval by 
the applicable IRBs/IECs.  These requirements should in no way prevent any immediate 
action from being taken by the investigator, or by the sponsor, in the interest of preserving 
the safety of all subjects included in the study.  If the investigator determines that an 
immediate change to or deviation from the protocol is necessary for safety reasons to 
eliminate an immediate hazard to the subjects, the sponsor’s medical monitor and the 
IRB/IEC for the site must be notified immediately.  The sponsor must notify the health or 
regulatory authority as required per local regulations.
Protocol amendments that affect only administrative aspects of the study may not require 
submission to health or regulatory authority or the IRB/IEC, but the health or regulatory 
authority and IRB/IEC should be kept informed of such changes as required by local 
regulations.  In these cases, the sponsor may be required to send a letter to the IRB/IEC and 
the Competent Authorities detailing such changes.
11.2
Adherence to the Protocol
The investigator will conduct the study in strict accordance with the protocol (refer to ICH 
E6, Section 4.5).
11.3
Monitoring Procedures
The sponsor’s/CRO’s CRA will maintain contact with the investigator and designated staff 
by telephone, letter, or email between study visits.  Monitoring visits to each site will be 
conducted by the assigned CRA as described in the monitoring plan.  The investigator will 
allow the CRA to inspect the clinical, laboratory, and pharmacy facilities to assure 
compliance with GCP and local regulatory requirements.  The CRFs and subject’s 
corresponding original medical records (source documents) are to be fully available for 
review by the sponsor’s representatives at regular intervals.  These reviews verify adherence 
to study protocol and data accuracy in accordance with local regulations.  All records at the 
site are subject to inspection by the local auditing agency and IRB/IEC review.

APD356-A001-403
EisaiFINAL (v4.0):  03 Nov 2016
Confidential
Page 72 of 81
In accordance with ICH E6, Section 1.52, source documents include, but are not limited to 
the following:
•
Clinic, office, or hospital charts
•
Copies or transcribed health care provider notes which have been certified for accuracy 
after production
•
Recorded data from automated instruments such as IxRS, x-rays, and other imaging 
reports, (eg, sonograms, computerized tomography scans, magnetic resonance images, 
radioactive images, ECGs, rhythm strips, EEGs, polysomnographs, pulmonary function 
tests) regardless of how these images are stored, including microfiche and photographic 
negatives
•
Pain, quality of life, or medical history questionnaires completed by subjects
•
Records of telephone contacts
•
Diaries or evaluation checklists
•
Drug distribution and accountability logs maintained in pharmacies or by research 
personnel
•
Laboratory results and other laboratory test outputs (eg, urine pregnancy test result 
documentation and urine dip-sticks)
•
Correspondence regarding a study subject’s treatment between physicians or memoranda 
sent to the IRBs/IECs
•
CRF components (eg, questionnaires) that are completed directly by subjects and serve as 
their own source
11.4
Recording of Data
A CRF is required and must be completed for each subject by qualified and authorized 
personnel.  All data on the CRF must reflect the corresponding source document, except 
when a section of the CRF itself is used as source document.  Any correction to entries made 
on the CRF must be documented in a valid audit trail where the correction is dated, the 
individual making the correct is identified, the reason for the change is stated, and the 
original data are not obscured.  Only data required by the protocol for the purposes of the 
study should be collected.
The investigator must sign each CRF.  The investigator will report the CRFs to the sponsor 
and retain a copy of the CRFs.
11.5
Identification of Source Data
All data to be recorded on the CRF must reflect the corresponding source documents.

11.6
Retention of Records
The circumstances of completion or termination of the study notwithstanding, the 
investigator is responsible for retaining all study documents, including but not limited to the 
protocol, copies of CRFs, the Investigator's Brochure, and regulatory agency registration 
documents (eg, Form FDA 1572 ICFs, and IRB/IEC correspondence).  In addition, the 
sponsor will send a list of treatment codes by study subject to the investigator after the 
clinical database for this study has been locked.  The site should plan to retain study 
documents, as directed by the sponsor, for at least 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region or at least 3 years have elapsed since the formal 
discontinuation of clinical development of the investigational product.
It is requested that at the completion of the required retention period, or should the 
investigator retire or relocate, the investigator contact the sponsor, allowing the sponsor the 
option of permanently retaining the study records.
11.7
Auditing Procedures and Inspection
In addition to the routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of ICH GCP and all applicable local 
regulations.  If a government regulatory authority requests an inspection during the study or 
after its completion, the investigator must inform the sponsor immediately.
11.8
Handling of Study Drug
All study drugs will be supplied to the PI (or a designated pharmacist) by the sponsor.  Drug 
supplies must be kept in an appropriate secure area (eg, locked cabinet) and stored according 
to the conditions specified on the drug labels.  Investigational product will be stored in 
accordance with the DEA Regulations for Scheduled III - V Drugs and labeled storage 
conditions.  The investigator (or a designated pharmacist) must maintain an accurate record 
of the shipment and dispensing of the study drug in a drug accountability ledger, a copy of 
which must be given to the sponsor at the end of the study.  An accurate record of the date 
and amount of study drug dispensed to each subject must be available for inspection at any 
time.  The CRA will visit the site and review these documents along with all other study 
conduct documents at appropriate intervals once study drug has been received by the site.
All drug supplies are to be used only for this study and not for any other purpose.  The 
investigator (or site personnel) must not destroy any drug labels or any partly used or unused 
drug supply before approval to do so by the sponsor.  At the conclusion of the study and as 
appropriate during the study, the investigator (or a designated pharmacist) will return all used 
and unused drug containers, drug labels, and a copy of the completed drug disposition form 
to the sponsor’s CRA.

Appendix 2
Family-Based Lifestyle Program
Program Overview
All subjects and their caregivers (participating parent or guardian) in Study 403 will be 
encouraged to participate in a standardized weight management program for adolescents 
consisting of multicomponent behavior therapy.  The therapy will focus on healthy eating, 
physical activity, and lifestyle changes that will facilitate weight loss and weight-loss 
maintenance. The role of the caregivers is to support their child or adolescents’ lifestyle 
changes and their taking of study medication.
The objectives of this program are as follows:

Develop a weight management program for all Belviq XR study participants and their 
caregivers (caregivers are instructed in methods to support their adolescents’ progress 
but caregivers are themselves not instructed to lose weight or take medication)

Standardize the weight management program across all study sites

Maximize participant retention

Promote participant’s adherence to both taking study medication and following the 
lifestyle program

decision to perform local 
echocardiograms 
on 
a 
pediatric subject if deemed 
medically indicated rather 
than burden the subject to 
undergo 
a 
mandated, 
unnecessary procedure.

pediatric development strategy
A single dose pharmacokinetic 
study in pediatric obese subjects 
(APD356-A001-026) indicated 
that patients with body weight 
greater than or equal to 60 kg 
can be administered a dose 
similar to that given to adults 
and adolescents.  Based on 
Centers for Disease Control and 
Prevention (CDC) growth chart 
data, almost all subjects over 
9 years of age are likely to be at 
or over 60 kg body weight.  
Therefore, children age 9 to 
11 years have been included in 
the current study.

population PK/ PD modeling
Study Design
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in obese 
children and adolescents, ages 9 to 17 years.  Approximately 360 subjects will be randomized in a 
1:1 ratio to Belviq XR 20 mg QD (180 subjects) and placebo (180 subjects).  Subjects will be 
stratified by age group and sex.  At least 30% of the total subjects should be ages 9 to 11 years.  
Subjects will receive Belviq XR 20 mg or placebo QD in a 1:1 ratio for up to 52 weeks. Throughout 
the duration of the study, subjects will be encouraged to adhere to a lifestyle modification program 
that includes diet and exercise counseling.
The study will consist of 2 phases: Prerandomization and Randomization.  The Prerandomization 
Phase will last up to 30 days and consist of 1 visit during which subjects will be screened for 
eligibility.  The Randomization Phase consists of a Treatment Period and a Follow-Up Period.  The 
Treatment Period will last for a maximum of 52 weeks, with visits at Weeks 1, 5, 8, 12, 20, 28, 36,
44, and 52.  The Follow-Up Period will extend from the End of Treatment visit to the End of Study 
visit.
Subjects who screen fail can be re-screened only once after 60 days.  All subjects will continue in the 
study until the 52-week evaluation is completed.  Subjects who discontinue treatment prematurely 
will be followed up until study completion.  
Number of Subjects
Approximately 700 subjects will be screened to provide 360 randomized subjects.

Pharmacokinetic Assessments
Plasma lorcaserin concentrations will be measured at Weeks 12, 28, 36, and 52 for analysis of 
population PK.  At Weeks 12, 28, and 52, subjects will be instructed to take their morning dose at the 
clinic.  Two blood samples for determination of plasma concentrations of lorcaserin will be taken at 
each of these visits: within 30 minutes before dosing and within 1 to 3 hours after dosing.  At the 
Week 36 visit, subjects will take the morning dose at home, and 1 blood sample for determination of 
plasma concentrations of lorcaserin will be collected at the investigational site within 4 to 6 hours 
after dosing.
Pharmacodynamic Assessments

Change from baseline in BMI 

Proportion (%) of subjects achieving at least a 5% and at least a 10% reduction in BMI
Other PD endpoints will be considered based on the data at the end of the study to explore their 
relationships with lorcaserin plasma exposure.
Pharmacogenomic/Pharmacogenetic Assessments
Not applicable
Safety Assessments
Safety assessments will consist of monitoring and recording all adverse events (AEs) and serious 
adverse events (SAEs); electrocardiograms (ECGs); laboratory evaluation for hematology, thyroid 
function, adrenal function and biochemical blood and urine biomarkers of bone health; blood 
chemistry and urine values; neuropsychiatric events; periodic measurement of vital signs,
neuromuscular signs for screening potential serotonin syndrome, and signs or symptoms of priapism 
and prolactinemia; and performance of physical examinations.
In patients with potential 
prolactin-related AEs, such as galactorrhea, changes in libido, or changes to menstrual cycle, 
prolactin level will be measured and assessed.
Study drug effect on growth of children and 
adolescents will be evaluated using the CDC growth chart at Baseline, and Weeks 5, 12, 28, 36, 52, 
and at Follow-Up; a full physical examination, at Baseline, Weeks 12, 28, 52, and at Follow-Up; and 
bone age determination by x-ray of the hand at Baseline, Weeks 12, 28, and 52.
Children and 
adolescent sexual maturation will be evaluated by assessing sex hormones and self-reported changes 
in Tanner Staging at Baseline, Weeks 28 and 52, and at Follow-Up. Any subject with symptoms or 
signs of cardiac valvular disease or pulmonary hypertension may be evaluated by local 
echocardiographic assessment at the discretion of the investigator if deemed medically indicated.  
The (C-SSRS) will be used to assess all children and adolescents in the study for any signal of 
depression or suicidal ideation or behavior.  Additionally, mood will be assessed using the CDI-2 and 
effects on cognitive function will be assessed using WRAML-2.
Bioanalytical Methods
Lorcaserin will be quantified in plasma using a validated liquid chromatography method coupled with 
tandem mass spectrometry.

The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change from 
baseline in BMI will be analyzed using the mixed effect model repeated measurement analysis 
(MMRM) assuming the missing data is missing at random (MAR), with factors of treatment visits 
(Baseline, Week 1, 5, 8, 12, 20, 28, 36, 44, and 52), age group (9 to 11 years old and 12 to 17 years 
old), sex (male and female), treatment-by-visit interaction as fixed effect, subjects as random effect,
and the baseline BMI as a covariate.  The unstructured covariance matrix will be used in the analysis 
and the treatment comparison at Week 52 will be the event of interest.  In case of a convergence 
issue, the Toeplitz covariance structure will be used in the model.
Subgroup analyses and additional sensitivity analyses will be performed as appropriate including 
multiple imputation methods assuming the missing values are MAR and missing not at random 
(MNAR) to handle missing data.
The following analyses will be considered as sensitivity analyses:

PP analysis:  The same primary efficacy analyses described above will be repeated based on 
the PP.

Multiple imputation (MI):  the same primary efficacy analyses described above will be 
analyzed using MI for impute the missing data, assuming the missing values are MAR and 
MNAR.

Change from baseline in standardized BMI score (Z-score):  The same primary efficacy 
analyses described above will be repeated using Z-score.
Additional sensitivity analyses may also be explored and described in the SAP, if deemed 
appropriate.
Key Secondary Efficacy Analyses
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 5% BMI 
reduction at Week 52. The secondary efficacy endpoint will be analyzed only if the test for the 
primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be analyzed using 
a logistic regression model with factors of treatment, age group (9 to 11 years old and 12 to 17 years 
old), sex (male and female), and baseline BMI as a covariate using FAS.  Subjects with any missing 
assessment at Week 52 will be considered as treatment failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be analyzed 
using MMRM and categorical variables will be analyzed using the Cochran Mantel Haenszel test, 
Chi-square test, or logistic regression as appropriate.  Additional analysis may be performed as

needed using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including age group (9 to 
11 years old and 12 to 17 years old), sex (male and female), and race (white, black, Asian, and other).  
Additional subgroups may be explored, if deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and sensitivity 
analyses.
Pharmacokinetic Analyses
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling. The effect of covariates such as baseline characteristics or 
demographics on PK will be explored. Derived exposure parameters such as the maximum observed 
concentration and the area under the concentration-time curve from time 0 to 24 hours at steady-state 
will be calculated from the final PK model using individual posterior estimates of the PK parameters 
and from dosing history. The PK analysis set will be used for this analysis.
Pharmacodynamic Analyses
Change from Baseline in BMI will be assessed as the PD analysis.  The PD analysis set will be used 
for this analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% and 
≥10% BMI reduction, and change in waist circumference from baseline) will also assessed as part of 
the PD analysis.  The PK/PD analysis set will be used for this analysis.
Pharmacokinetic/Pharmacodynamic Analyses
Population PK/PD modeling will be used to explore the relationship between lorcaserin plasma 
exposure and response, including but not limited to change in BMI from baseline and the probability 
of achieving at least a 5% and at least a 10% change in BMI from baseline to Week 52.  Additionally, 
exposure-safety relationships for select safety parameters may be explored graphically depending on 
the data at the end of study.  Any emergent relationship may be modeled as appropriate.  Any 
parameters based on the study data may be considered for exploratory assessment for its relationship 
to PK.
Pharmacogenomic/Pharmacogenetic Analyses
Not applicable
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments including the 
incidence of AEs (including changes from baseline in physical examination), growth (CDC growth 
chart and bone age determined by x-ray of the hand), sexual maturation (Tanner Staging), 
out-of-normal-range laboratory safety test values, change from baseline in laboratory safety test 
values (including biomarkers), ECGs, and vital sign measurements will be summarized by treatment 
group using descriptive statistics or frequency count as appropriate.  In addition, suicidal ideation, 
cognitive function, behavior, and mood will be evaluated by the C-SSRS, WRAML-2, CDI-2, and 
C-SSRS, respectively, and will also be summarized by treatment group using descriptive statistics or 
frequency count as appropriate. All WRAML-2 raw scores from the Core Battery will be converted 
to age and gender standard scores for purposes of intra individual comparisons
No hypothesis testing will be performed for the safety assessment.

Sample Size Rationale
The proposed sample size is based on the comparison of the primary efficacy endpoint, change in 
BMI from Baseline to Week 52 between the Belviq XR 20-mg treatment group and placebo group.  
Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 360 subjects in a 1:1 ratio 
(n=180 in the Belviq XR 20-mg treatment group; n=180 in the placebo group) will have at least 
90% power to detect a treatment difference of 1 kg/m2 in BMI, using a 2-sided t-test with α=0.05.  
Assuming the proportion of subjects achieving at least a 5% BMI reduction at Week 52 is 20% for 
the placebo group and a 40% dropout rate, this sample of 360 subjects (180 subjects for Belviq XR 
20 mg and 180 subjects for placebo) will also have greater than 85% power to detect an absolute 
difference of 20% between the Belviq XR 20-mg group and the placebo group, using a 2-sided 
Fisher’s Exact test with α=0.05. The assumption used in the sample size calculation is based on the 
2 pivotal lorcaserin studies APD356-009 and APD356-011 in obese and overweight non-diabetic 
adult subjects.

ETHICS
5.1
Institutional Review Boards/Independent Ethics Committees
The protocol, Informed Consent Form (ICF), and appropriate related documents must be 
reviewed and approved by an Institutional Review Board (IRB) or Independent Ethics 
Committee (IEC) constituted and functioning in accordance with International Conference on 
Harmonisation (ICH) Good Clinical Practice (ICH E6), Section 3, and any local regulations 
(eg, Federal Regulations, Title 21 Code of Federal Regulations [21 CFR] Part 56).  Any 
protocol amendment or revision to the ICF will be resubmitted to the IRB/IEC for review and 
approval, except for changes involving only logistical or administrative aspects of the study 
(eg, change in clinical research associate [CRA], change of telephone number[s]).  
Documentation of IRB/IEC compliance with the ICH E6 and any local regulations regarding 
constitution and review conduct will be provided to the sponsor.
A signed letter of study approval from the IRB/IEC chairman must be sent to the principal 
investigator (PI) with a copy to the sponsor before study start and the release of any study 
drug to the site by the sponsor or its designee (ICH E6, Section 4.4).  If the IRB/IEC decides 
to suspend or terminate the study, the investigator will immediately send the notice of study 
suspension or termination by the IRB/IEC to the sponsor.
Study progress is to be reported to IRB/IECs annually (or as required) by the investigator or 
sponsor, depending on local regulatory obligations.  If the investigator is required to report to 
the IRB/IEC, he/she will forward a copy to the sponsor at the time of each periodic report.  
The investigator(s) or the sponsor will submit, depending on local regulations, periodic 
reports and inform the IRB/IEC of any reportable adverse events (AEs) per ICH guidelines 
and local IRB/IEC standards of practice.  Upon completion of the study, the investigator will 
provide the IRB/IEC with a brief report of the outcome of the study, if required.
At the end of the study, the sponsor should notify the IRB/IEC and Competent Authority 
within 90 days.  The end of the study will be the date of the last study visit for the last subject 
in the study.  The sponsor should also provide the IRB/IEC with a summary of the study’s 
outcome.
In the case of early termination or a temporary halt of the study, the investigator should 
notify the IRB/IEC and Competent Authority within 15 calendar days, and a detailed written 
explanation of the reasons for the termination/halt should be given.

clinical studies, including Part 50 and Part 56 concerning informed subject consent 
and IRB regulations and applicable sections of US 21 CFR Part 312
5.3
Subject Information and Informed Consent
As part of administering the informed consent document, the investigator must explain to 
each subject and guardian/legally authorized representative the nature of the study, its 
purpose, the procedures involved, the expected duration, the potential risks and benefits 
involved, any potential discomfort, potential alternative procedure(s) or course(s) of 
treatment available to the subject, and the extent of maintaining confidentiality of the 
subject’s records.  Each subject must be informed that participation in the study is voluntary, 
that he/she may withdraw from the study at any time, and that withdrawal of consent will not 
affect his/her subsequent medical treatment or relationship with the treating physician.
This informed consent should be given by means of a standard written statement, written in 
nontechnical language.  The subject or the subject’s legally acceptable representative should 
understand the statement before signing and dating it and will be given a copy of the signed 
document.  If a subject is unable to read or if a legally acceptable representative is unable to 
read, an impartial witness should be present during the entire informed consent discussion.  
After the ICF and any other written information to be provided to subjects is read and 
explained to the subject or the subject’s legally acceptable representative, and after the 
subject or the subject’s legally acceptable representative has orally consented to the subject’s 
participation in the study and, if capable of doing so, has signed and personally dated the 
ICF, the witness should sign and personally date the consent form.  The subject will be asked 
to sign an ICF before any study-specific procedures are performed.  No subject can enter the 
study before his/her informed consent has been obtained.  The adolescent participant will 
provide written assent and the caregiver/guardian will provide written informed consent.
An unsigned copy of an IRB/IEC-approved ICF must be prepared in accordance with 
ICH E6, Section 4, and all applicable local regulations (Federal Regulations, 
Title 21 CFR Part 50, for studies in the United States).  Each subject must sign an approved 
ICF before study participation.  The form must be signed and dated by the appropriate 
parties.  The original, signed ICF for each subject will be verified by the sponsor and kept on 
file according to local procedures at the site.

INTRODUCTION
7.1
Indication
Obesity
Obesity has become a global epidemic in western civilization, causing a serious public health 
concern.  In the United States, the prevalence of obesity in adolescents ages 12 and 19 years
has almost doubled over the past 2 decades.  The rate increased from 10.5% between 1988 
and 1994 to 20.5% between 2011 and 2012 (CDC/NCHS, 2013).  The prevalence of obesity 
in children in United States is also high.  The United States Centers for Disease Control and
Prevention (CDC) reported in 2012 that 17.7% of children ages 6 to 11 years are obese.
Obesity in children and adolescents, defined in the United States as greater than or equal to 
the 95th percentile in gender- and age-specific body mass index (BMI), continues to grow at 
an alarming rate in the United States and globally.  Based on data (Wang and Lobstein, 2006) 
using various criteria for the definition of obesity that included more than 30 countries in 
Europe, North America, Asia, and the West Pacific, prevalence of obesity in these countries 
has also increased significantly, at a rate comparable to that in the United States.
Childhood and adolescent obesity has many negative implications for both the health and 
well-being of the individual as well as for society.  These include increased susceptibility to a 
host of diseases, chronic health disorders, psychological disorders, and premature death 
(Flegal, et al., 2005; Rofey, et al., 2009).  Increases in the prevalence of overweight and 
obese adolescents may result in a decrease in life expectancy for the 1st time in 200 years
(Peeters , et al, 2003).
As a result, there is a significant impact on the cost of healthcare.  It is estimated that medical 
costs due to overweight adolescents are approximately $14 billion per year in the United 
States (Trasande and Chatterjee, 2009).  Obesity-related medical costs in general are
expected to rise significantly because today’s obese children are likely to become tomorrow’s 
obese adults.
Current approaches to weight management include lifestyle modification, pharmacotherapy, 
and invasive bariatric procedures.  Lifestyle modification involves a combination of diet, 
exercise, and behavioral change, and is the preferred and essential strategy for weight 
management in obese and overweight individuals.  Although lifestyle modification can be 
very efficacious in some patients, adherence to the prescribed regimens is often poor.  As 
such, lifestyle modification alone is often not adequate and the weight loss is often transient.  
On the other hand, bariatric surgery and various other invasive procedures are generally 
reserved for the severely obese population. 
Pharmacotherapy can play a significant role in weight management programs, and is often 
combined with lifestyle modification to enhance weight loss beyond that which is normally 
achieved with diet and exercise alone.  Current pharmacotherapies offer the potential to 
significantly augment weight loss when combined with diet and exercise.

The current standard of care for treatment of obesity in pediatric subjects ranges from 
lifestyle intervention in children less than 8 years of age to use of pharmacotherapy in 
adolescents over 12 years of age (McGovern, et al, 2008; Spear, et al, 2007).  Xenical®
(orlistat) is currently the only product available for weight control in obese adolescent 
patients 12 to 16 years of age.  However, it is associated with gastrointestinal side effects 
(Xenical PI. 2015), and the treatment effect of Xenical is modest. In a study that included 
539 obese adolescents with BMI above the 97th percentile, Xenical demonstrated a 0.86 BMI 
reduction relative to placebo after 52 weeks of treatment (-0.55 BMI in the Xenical treatment 
group versus +0.31 BMI in the placebo group) (FDA, 2003; Chanoine, et al, 2005).
Obtaining maximum retention in the study is a major goal in order to minimize missing data.  
A number of strategies have been used in prior adolescent weight loss studies that will be 
used in the present study to help retain participants.  These include a highly trained and 
competent staff, ample waiting area, readily available parking (at no cost), access to mass 
transit, and reminder and follow-up calls.  In addition, we will provide fun and interactive 
group sessions with games and hands-on nutrition and physical activity demonstrations, 
random raffle drawings, social events, birthday and holiday cards, and newsletters.  Further, 
we will make home visits for assessments for families, as needed, to maximize data 
collection. We anticipate achieving a 75% or greater retention rate at Month 12. By using 
these retention strategies, we hope that we will maximize participant retention, which will 
help us cope with missing data.

APD356/Belviq (lorcaserin hydrochloride)
7.1.1.1
Mechanism of Action
Belviq is a selective serotonin 2c receptor agonist which was approved by the US Food and 
Drug Administration (FDA) on 27 Jun 2012 as an adjunct to a reduced-calorie diet and 
increased physical activity for chronic weight management in adult patients with a BMI of at 
least 30 kg/m2 (obese), or adult patients with a BMI greater than or equal to 27 kg/m2
(overweight) in the presence of at least 1 weight-related comorbid condition.
7.1.1.2
Clinical Experience with APD356/Belviq (lorcaserin hydrochloride)
The Phase 3 clinical evaluation of Belviq in studies of more than 7700 adult subjects, 
including 604 subjects with Type 2 diabetes mellitus, demonstrated clinically meaningful 
efficacy and a safety profile that includes minimal and easily managed risks.  In each of the 
individual studies and in the pooled efficacy analyses, the Belviq dose met the following 
prespecified endpoints:

Page 25 of 85

A significantly greater proportion of adult subjects taking Belviq 10 mg twice per day 
(BID) (47%) lost at least 5% of baseline body weight at 52 weeks as compared to 
subjects taking placebo (23%).  A significantly greater proportion of subjects taking 
Belviq 10 mg BID (22.4%) lost at least 10% of baseline body weight at 1 year as 
compared to subjects taking placebo (8.7%). 

The mean weight loss at 1 year in adult subjects taking Belviq 10 mg BID (-5.8 kg) 
was significantly greater than that in subjects taking placebo (-2.5 kg).
An integrated evaluation of the data from the pediatric, adolescent, and adult subjects 
revealed that the relationship between lorcaserin area under the curve (AUC) and body 
weight in pediatric and adult subjects is consistent irrespective of the individual studies or 
age range of the study population. Irrespective of age, lorcaserin AUC values in the pediatric 
subjects with body weight of greater than 60 kg overlapped with the data observed from the 
studies involving adult subjects, suggesting a fixed dose approach similar to adults can be 
used for children and adolescent subjects with body weight greater than 60 kg.
In preadolescent and adolescent obese populations, it is anticipated that Belviq XR will result 
in similar effects.
As part of FDA postmarketing requirements, this study is designed to 
characterize the efficacy and safety of Belviq XR in adolescent obese populations in the 
United States, as well as in children ages 9 to 11 years.  It is also intended to support an 
indication for chronic weight management for obese children and adolescents ages 9 to 
17 years. 
It is intended to have 20 subjects treated with lorcaserin XR in each age group and 
10 subjects on lorcaserin XR for 52 weeks in each age groups, which is well above the 
numbers of subjects in adolescent studies with other products (ie, ezetimibe combination 
therapy with reductase inhibitors in primary hypercholesterolemia and heterozygous familial 
hypercholesterolemia in study involved 10 to 17 years old). The total number of subjects at 
baseline for combination therapy was 5 subjects at age 10 years old and 9 subjects at age 
11 years old group (FDA, 2007).
7.1.2
Study Rationale
There is no specific FDA guidance for the approval of a weight loss product for children and 
adolescents. In adults, the Division’s 2007 draft Guidance for Industry Developing Products 
for Weight Management indicate that the product needs to satisfy either of the following
mean or categorical criteria after 1 year of treatment:

The difference in mean weight loss between the active-product and placebo-treated 
groups is at least 5% and the difference is statistically significant.

The proportion of subjects who lose at least 5% of baseline body weight in the 
active-product group is at least 35%, is approximately double the proportion of 
subjects in the placebo-treated group who lose at least 5% of baseline body weight, 
and the difference between groups is statistically significant.

FDA awarded a weight management indication for Belviq based on Phase 3 study results 
which achieved the categorical criteria. In a Phase 3 study, a significantly greater proportion 
of subjects taking Belviq (47%) lost at least 5% of baseline body weight at 1 year as 
compared to subjects taking a placebo (23%).  It is anticipated that a similar effect will be 
demonstrated in older children (9 to 11 years of age) and obese adolescents, where weight 
loss will be assessed using BMI measurements to account for growth. In this study, the 
objective is to demonstrate that BMI reduction will be achieved during 52 weeks of treatment 
with Belviq XR 20 mg administered once daily (QD) compared to placebo in obese children 
and adolescents.
In the Phase 3 orlistat study in obese adolescents and children mentioned above, the 
proportion of subjects who lost at least 5% body weight is relatively low. At the end of the 
study at Week 52, only 26.5% of the subjects achieved a 5% or greater BMI reduction 
compared to 15.7% in the placebo group. The placebo-corrected BMI reduction was about 
0.86 kg/m2.  
There are limited trials for weight reduction in the adolescent population, ages 12 to 17 years,
and none in children under the age of 9 years (Peirson, et al, 2015).  Thirty-one studies 
(29 behavioral, 2 pharmacological and behavioral) were included in a meta-analysis of 
randomized studies conducted in primary care centers in overweight and obese children and 
youth ages 2 to 18 years using behavioral (diet, exercise, and lifestyle) and pharmacological 
interventions and providing 6-month postbaseline BMI or prevalence of overweight or 
obesity. 
Both interventions showed a significant effect on BMI in favor of treatment 
(behavioral: 
standardized mean difference [SMD] -0.54, 95% confidence interval 
[CI] -0.73, -0.36; orlistat plus behavioral: SMD -0.43, 95% CI -0.60, -0.25). The studies 
reported no significant difference between groups in the likelihood of reduced prevalence of 
overweight or overweight and obese. A great deal of variation was noted across efficacious 
interventions.
In conclusion, this meta-analysis demonstrated low-quality evidence that 
behavioral treatments alone are associated with a smaller effect in terms of reduced BMI 
compared with the effect shown by combined behavioral and pharmacological interventions. 
This may be because the effect size in the randomized, double blind, placebo controlled,
phase 3 orlistat study in adolescents was relatively low and there was a lack of maintenance 
effect. These subjects started to regain their BMI after 6 months of treatment. At end of the 
study, only 26.5% of subjects achieved a 5% or greater BMI reduction compared to 15.7% in 
placebo group. In a sibutramine Phase 3 study in obese adolescents, a substantially higher 
proportion of subjects (69%) treated with sibutramine achieved at least a 5% BMI reduction 
compared to 21% of subjects in the placebo group. In addition, sibutramine resulted in a
substantial reduction in mean BMI (between-group difference, 2.9 kg/m2) and mean weight 
(between-group difference, 8.4 kg) compared to placebo (Berkowitz, et al, 2006).  Unlike the 
weight loss effect of Belviq in adults and sibutramine in adolescents, subjects in the orlistat 
study started to increase their BMI after 6 months of treatment.
In this study, it is assumed that treatment with Belviq XR 20 mg will lead to a BMI reduction
of more than 1 kg/m2, and a higher proportion of subjects will achieve more than a 5% and 
10% BMI reduction compared to placebo.  A between-group difference of 24% is the basis 
for the conservative assumption of a 20% effect size in the current study.

In addition, the total sample size of 360 subjects will be adequate to assess safety and 
exposure based on previous adolescent studies with weight management products (orlistat 
and sibutramine) (FDA, 2003; Chanoine, et al, 2005; Berkowitz, et al, 2006) and other 
metabolic or dyslipidemia medication products (ezetimibe, simvastatin) (FDA, 2007).

INVESTIGATIONAL PLAN
9.1
Overall Study Design and Plan
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in 
obese children and adolescents ages 9 to 17 years.  Approximately 360 subjects will be 
randomized in a 1:1 ratio to Belviq XR 20 mg QD (180 subjects) and placebo (180 subjects).  
Subjects will be stratified by age group and sex.  At least 30% of total subjects should be 
ages 9 to 11 years for the reasons outlined above in Section 7.1.1.2.  Subjects will receive 
Belviq XR 20 mg or placebo QD in a 1:1 ratio for up to 52 weeks. Throughout the duration 
of the study, subjects will be encouraged to adhere to a lifestyle modification program that 
includes diet and exercise counseling (see Appendix 2).  
The study will consist of 2 phases:
Prerandomization and Randomization.  The 
Prerandomization Phase will last up to 30 days and consists of 1 visit during which subjects 
will be screened for eligibility.  The Randomization Phase consists of a Treatment Period and 
a Follow-Up Period.  The Treatment Period will last for a maximum of 52 weeks, with visits 
at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52; the Follow-Up Period will extend from the 
End of Treatment (EOT) visit to the End of Study (EOS) visit.
Subjects who screen fail can be re-screened only once after 60 days.  All subjects will 
continue in the study until the 52-week evaluation is completed.  Subjects who discontinue 
treatment prematurely will be followed up until study completion.

Prerandomization/Pretreatment Phase
Screening will occur during the Prerandomization Phase at Visit 1
9.1.1.1
Screening Period
The purpose of the Screening Period is to obtain the informed consent and assent and to 
establish protocol eligibility.  Procedures to be followed when obtaining informed consent 
are detailed in Section 5.3.  Careful initial screening is important in the recruitment of 
families who both fully understand the requirements of this 1 year, randomized, controlled 
trial and are truly interested in participation.  Interested caregivers and adolescents will be 
screened by phone to assess preliminary entry criteria.  Candidates will be given a brief 
description of the program and general study requirements, with an adolescent and a 
caregiver who is willing to participate.  If preliminary entry criteria are met, adolescents and 
their caregivers will be invited to an initial in-clinic meeting to further discuss the study.  A 
complete description of the study including assessments, the number of visits, the lifestyle 
program, the fact that the adolescent would be taking either the study drug or a placebo, the
duration of the study, and the necessity of having an adolescent wishing to participate as well 
as a participating caregiver will be described.  Consent and assent will be obtained and copies 
of the signed forms will be provided to families.  The importance of the study and its 
scientific merit will be discussed.  Ineligible adolescents will be referred to local weight 
management resources.  Screening period assessments and timing thereof are shown in 
Section 9.5.2.

Discussion of Study Design, Including Choice of Control Groups
The proposed dose and dosing frequency of Belviq XR in this study is 20 mg QD.  The PK 
parameters of a single 10-mg dose of Belviq were evaluated in healthy, adolescent obese 
subjects in Study APD356-025 and healthy, obese pediatric subjects ages 6 to 11 years in 
Study APD356-A001-026.  Overall, the PK parameters of Belviq and its main metabolites, 
M1 and M5, were similar to those in adults.  Following a single, oral administration of 
Belviq 10 mg to a total of 8 healthy adolescent (age 12 to 17 years) obese subjects, the mean 
maximum concentration observed and the area under the concentration-time curve from time 
zero to infinity (AUC(0-inf)) were 36.5 ng/mL and 464 hr×ng/mL, respectively.  The mean 
Belviq terminal phase half-life was 9.70 hours, similar to that observed in adults, thus 
supporting a similar dosing frequency (QD) in adolescent subjects.
Additionally, a single dose PK study in 8 healthy obese pediatric subjects ages 6 to 11 years 
of age was performed. The PK analysis after a single 10-mg dose of lorcaserin revealed that 
the lorcaserin AUC(0-inf) values tended to increase with decreasing body weight and age.
However, the body weight normalized AUC(0-inf) values were similar across the age groups, 
therefore the data indicated no effect of age on the lorcaserin PK. Integrated assessment of 
the PK versus body weight relationship, pooling the data from pediatric and adult subjects 
from previous studies, suggested that the lorcaserin area under the curve values for subjects 
with body weight of at least 60 kg overlapped with the area under the curve values from 
adolescents and adults. Therefore, no dose adjustment relative to adults and adolescents is 
deemed necessary for pediatric subjects with a body weight of at least 60 kg.
Based on CDC growth charts, the likelihood of enrolling subjects who are younger than 
9 years of age with body weight of at least 60 kg is low; therefore, the current study is 
designed to enroll the subjects between 9 to 17 years of age.
The targeted study population comprises 360 obese children and adolescents 9 to 17 years of
age.
Obese adolescents will be identified using gender- and age-specific BMI measurement.  
Obesity in adolescents is defined by US Expert committee recommendations as BMI in or 
above the 95th percentile (Barlow, 2007).
Obesity in children will be identified using 
gender- and age-specific BMI measurement.  Obesity in children (9 to 11 years of age) is 
defined by The American Academy of Pediatrics 2007 recommendation as BMI in the 
99th percentile and at least 1 co-morbidity (Spear, et al, 2007).

The proposed patient population is consistent with the recommendations in the 
2007 American Academy of Pediatrics article, Recommendations for Treatment of Child and 
Adolescent Overweight and Obesity (Spear, et al, 2007), which supports medication use in 
the 6 to 11 year age group as part of a staged approach (Tertiary Care Intervention in patients 
with a BMI 99th percentile and at least 1 co-morbidity).  
Randomization will be used in this study to avoid bias in the assignment of subjects to 
treatment, to increase the likelihood that known and unknown subject attributes (eg, 
demographics, baseline characteristics) are balanced across treatment groups, and to ensure 
the validity of statistical comparisons across treatment groups.  Blinding to treatment will be 
used to reduce potential bias during data collection and evaluation of endpoints.
9.3
Selection of Study Population
Approximately 700 subjects will be screened to ensure that 360 subjects will be randomized.

thermometric values over a specific time period can be recorded and retrieved as required.
9.4.3
Method of Assigning Subjects to Treatment Groups
Subjects will be assigned to treatments based on a computer-generated randomization 
scheme that will be reviewed and approved by an independent statistician.  The 
randomization scheme and identification for each subject will be included in the final clinical 
study report for this study.
Subjects will be centrally stratified by age group (9 to 11 years old and 12 to 17 years old)
and sex (male and female).  Within each stratum, subjects will be randomized to receive 
either Belviq XR 20 mg or placebo QD in a 1:1 ratio.  It is planned that at least 30% of the 
subjects will be enrolled into the 9 to 11 year age group.  
Randomization will be performed centrally by an interactive voice or web response system 
(IxRS).  The IxRS or clinical supply vendor will generate the randomized identification
numbers to be included on study packaging.  Upon signature of the ICF, the investigator or 
designee will access the IxRS to register the subject information.  At Randomization, the 
IxRS will assign each subject a unique randomization number.  At each subsequent visit 
during the Treatment Period and Follow-Up Period, the investigator or designee will access 
IxRS to obtain dispensing information and to register the subject’s visit.
9.4.4
Selection and Timing of Dose for Each Subject
Subjects should take the study medication once daily, and be encouraged to take the study 
medication with an adequate amount of water (8 oz. or 240 mL).
9.4.5
Blinding
During the Randomization Phase, subjects and all personnel involved with the conduct and 
interpretation of the study, including investigators, site personnel, and sponsor staff will be 
blinded to the treatment codes.  Randomization data will be kept strictly confidential, filed 
securely by an appropriate group with the sponsor or CRO, and accessible only to authorized 
persons (eg, Eisai Global Safety) until the time of unblinding, per the SOP.
A master list of all treatments and the subject numbers associated with them will be 
maintained in a sealed envelope by the clinical supply vendor, the IxRS vendor, and the 
sponsor.  In the event that emergency conditions require knowledge of the study treatment 
given, the blind may be broken via the code breaker facility within the IxRS.  Emergency 
procedures for revealing drug codes are given in Section 9.5.4.5.  If possible, before breaking 
the blind, the investigator should consult with the sponsor or designee to ascertain the 
necessity of breaking the code.

9.5.1.5.1 ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered an investigational product.  An AE does not necessarily have a causal 
relationship with the medicinal product.  For this study, the study drug is Belviq XR
(lorcaserin hydrochloride).
The criteria for identifying AEs in this study are:
•
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or 
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE)
•
Any new disease or exacerbation of an existing disease 
•
Any deterioration in non-protocol-required measurements of a laboratory value or other 
clinical test (eg, ECG, x-ray) that results in symptoms, a change in treatment, or 
discontinuation of study drug
•
Recurrence of an intermittent medical condition (eg, headache) not present pretreatment 
(Baseline)
•
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of study drug, or withholding 
of study drug, whether prescribed in the protocol or not.
All AEs observed during the study will be reported on the Adverse Event CRF.  All AEs, 
regardless of relationship to study drug or procedure, should be collected beginning from the 
time the subject signs the study ICF through the last visit in the Treatment Phase.  Subjects 
who fail screening primarily due to AE(s) must have the AE(s) leading to screen failure 
reported on the Screening Disposition CRF.  SAEs will be collected for 28 days after the last 
dose.
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute 
an AE.  Medical and scientific judgment should be exercised in deciding whether an isolated 
laboratory abnormality should be classified as an AE.  Any laboratory abnormality 
considered to constitute an AE should be reported on the Adverse Event CRF. 
Abnormal ECG (corrected QT interval [QTc]) results, if not otherwise considered part of a 
clinical symptom that is being reported as an AE, should be considered an AE if the QTc 
interval is greater than 450 msec and there is an increase of more than 60 msec from baseline.  
Any ECG abnormality that the investigator considers as an AE should be reported as such.

It is the responsibility of the investigator to review the results of the C-SSRS, CDI-2, and 
WRAML-2 in all subjects and determine if any result constitutes an AE.  Medical and 
scientific judgment should be exercised in deciding whether an isolated suicidality rating 
scale response should be classified as an AE (see Section 9.5.1.5.8 for a description of the 
C-SSRS).
All AEs must be followed for 28 days after the subject’s last dose or until resolution, 
whichever comes first.  All SAEs must be followed to resolution or, if resolution is unlikely, 
to stabilization.
Every effort must be made by the investigator to categorize each AE according to its 
severity and its relationship to the study treatment.
Assessing Severity of Adverse Events
Adverse events will be graded on a 3-point scale (mild, moderate, severe) and reported in the 
detail indicated on the CRF.  The definitions are as follows:
Mild
Discomfort noticed, but no disruption of normal daily activity
Moderate Discomfort sufficient to reduce or affect normal daily activity
Severe
Incapacitating, with inability to work or to perform normal daily activity
The criteria for assessing severity are different than those used for seriousness (see
Section 9.5.1.5.2 for the definition of an SAE).
Assessing Relationship to Study Treatment
Items to be considered when assessing the relationship of an AE to the study treatment are:
•
Temporal relationship of the onset of the event to the initiation of the study treatment
•
The course of the event, especially the effect of discontinuation of study treatment or 
reintroduction of study treatment, as applicable
•
Whether the event is known to be associated with the study treatment or with other 
similar treatments
•
The presence of risk factors in the study subject known to increase the occurrence of 
the event
•
The presence of nonstudy, treatment-related factors that are known to be associated 
with the occurrence of the event
Classification of Causality
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question:

Clinical Study Protocol
APD356-A001-403
Eisai
FINAL (v3.0):  14 Sep 2016
Confidential
Page 46 of 85
Is there a reasonable possibility that the study drug caused the AE?
Yes (related)
A causal relationship between the study drug and the AE is a reasonable 
possibility.
No (not related) A causal relationship between the study drug and the AE is not a 
reasonable possibility.
9.5.1.5.2 SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL 
SITUATIONS
An SAE is any untoward medical occurrence that at any dose:
•
Results in death
•
Is life-threatening (ie, the subject was at immediate risk of death from the AE as it 
occurred; this does not include an event that, had it occurred in a more severe form or 
was allowed to continue, might have caused death)
•
Requires inpatient hospitalization or prolongation of existing hospitalization
•
Results in persistent or significant disability/incapacity
•
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug)
Other important medical events that may not be immediately life-threatening or result in 
death or hospitalization but, when based on appropriate medical judgment, may jeopardize 
the subject or may require intervention to prevent one of the outcomes in the definition of 
SAE listed above should also be considered SAEs.  Medical and scientific judgment should 
be exercised in deciding whether expedited reporting is appropriate in such situations. 
For this study, the following events should always be considered serious and reported as an 
important medical event if it does not meet other serious criteria:
•
Serotonin syndrome (must have at least 1 of the following: Spontaneous clonus; 
Inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus)
•
Psychosis
•
Suicidal behavior
•
Priapism
•
New onset valvular heart disease
•
New onset pulmonary hypertension
•
Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas 
of the skin

Page 47 of 85
•
Fibroadenomas of the breast or ductal carcinoma in situ
The following additional study specific AE of interest should be reported using the 
procedures detailed in Reporting of SAEs (Section 9.5.4.1), even if the study specific event 
does not meet serious criteria.  If the event meets seriousness criteria, it should be reported as 
an SAE as above.  However, if the event listed below does not meet serious criteria, it should 
be noted as nonserious on the Adverse Event CRF:  

Suicidal ideation   

Euphoria 
In addition to the above, events associated with special situations include pregnancy or 
exposure to study drug through breastfeeding; AEs associated with study drug overdose, 
misuse, abuse, or medication error.  These events associated with special situations are to be 
captured using the SAE procedures but are to be considered as SAEs only if they meet 1 of 
the above criteria.  All AEs associated with special situations are to be reported on the CRF 
whether or not they meet the criteria for SAEs.  
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization.
The following hospitalizations are not considered to be SAEs because there is no “AE” (ie, 
there is no untoward medical occurrence) associated with the hospitalization:
•
Hospitalizations for respite care
•
Planned hospitalizations required by the protocol  
•
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed after study drug administration)
•
Hospitalization for administration of study drug or insertion of access for 
administration of study drug
•
Hospitalization for routine maintenance of a device (eg, battery replacement) that was

Clinical laboratory tests during the study will be performed by a central laboratory.  All 
blood and urine samples will be collected and sent to the central laboratory on the day of 
collection unless otherwise instructed.  In cases of a safety concern, blood samples will be 
split (or 2 samples drawn) to allow a local laboratory analysis in addition to the central 
laboratory.  
A laboratory abnormality may meet the criteria to qualify as an AE as described in this 
protocol (see Section 9.5.1.5.1) and the CRF Completion Guidelines.  In these instances, the 
AE corresponding to the laboratory abnormality will be recorded on the Adverse Event CRF.
9.5.1.5.4 VITAL SIGNS AND WEIGHT MEASUREMENTS
Vital sign measurements (ie, systolic and diastolic BP [mmHg], pulse [beats per minute], 
respiratory rate [per minute], body temperature [in centigrade]), and weight (kg) will be 
obtained as designated in the Schedule of Procedures/Assessments (Table 2) by a validated

method.  BP and pulse will be measured after the subject has been sitting for 5 minutes.  All 
BP measurements should be performed on the same arm, preferably by the same person. 
When vital signs are to be obtained concurrently with PK or other blood samples, the vital 
sign measurements will be performed before drawing blood samples in order to maximize the 
accuracy of blood sampling times while minimizing the potential effects of blood drawing on 
recordings obtained during safety assessments.
9.5.1.5.5 HEIGHT MEASUREMENTS
Height (cm) measurements will be obtained as designated in the Schedule of 
Procedures/Assessments (Table 2).  
9.5.1.5.6 PHYSICAL EXAMINATIONS
Physical
examinations will be performed as 
designated in
the Schedule of 
Procedures/Assessments (Table 2).  Documentation of the physical examination will be 
included in the source documentation at the site.  Significant findings at the Screening Visit 
will be recorded on the Medical History and Current Medical Conditions CRF.  Changes
from screening physical examination findings that meet the definition of an AE will be 
recorded on the Adverse Events CRF.
9.5.1.5.7 ELECTROCARDIOGRAMS
Twelve-lead 
ECGs 
will 
be 
obtained 
as 
designated 
in
the 
Schedule 
of 
Procedures/Assessments (Table 2). 
An ECG abnormality may meet the criteria of an AE as described in this protocol (see
Section 9.5.1.5.1) and the CRF Completion Guidelines.  In these instances, the AE 
corresponding to the ECG abnormality will be recorded on the Adverse Events CRF.
For ECG abnormalities meeting criteria of an SAE (see Section 9.5.1.5.2), the site must fax 
or email the SAE report including the ECG report to the sponsor using the SAE form (see 
Section 9.5.4.1).

9.5.1.5.8 OTHER SAFETY ASSESSMENTS
WRAML-2
The WRAML-2 administration will consist of the Core Battery, which provides scores on 
Verbal Memory, Visual Memory, and Attention/Concentration.  There are 6 subtests (2 for 
each area).
The tests provide standardized scores based on age and gender, and are 
appropriate for ages 5 to 90 years.  The WRAML-2 will be used to assess lorcaserin effects 
on cognitive function. In addition, signs and symptoms of cognitive related AEs, including 
impairments in attention, memory, and adverse effects on schoolwork will be captured in the 
eCRF.
CDI-2
The CDI-2 is a self-administered depression rating scale for use in children ages 7 to 
17 years.  It consists of 28 items and provides a total score, scores on 2 scales, and 
4 subscales.  CDI-2 will be used to assess lorcaserin effect on mood changes.
C-SSRS
The C-SSRS collects information pertinent to suicidal ideation and actions.  It consists of a 
Baseline version which will be administered at baseline and a Since Last Visit version which 
will be administered at the remaining visits.  C-SSRS will be used to assess signal of 
depression and suicidal ideation or behavior. It will be performed at Baseline and at study 
visits as designated in the Schedule of Procedures/Assessments (Table 2).
Signs and symptoms of priapism (painful erection) and hyperprolactinemia (menstrual cycle 
abnormalities or galactorrhea) will be captured in the eCRF.
Hand X-Ray will be evaluated for any potential negative effect on bone age as designated in 
the Schedules/Assessments (Table 2). Echocardiograms will be performed on the subjects 
with signs or symptoms of potential valvular disease or pulmonary hypertension. 
Echocardiogram confirmed cases of FDA-defined valvulopathy or pulmonary hypertension
will be captured by AE eCRF. Neuromuscular sign assessment for serotonin syndrome will 
be performed as designated in the Schedule of Procedures/Assessments (Table 2) to screen 
for potential serotonergic syndrome components. Serotonergic syndromes that meet the 
diagnostic criteria will be captured by AE eCRF.

Reporting of Serious Adverse Events, Pregnancy, and Events Associated 
with Special Situations
9.5.4.1
Reporting of Serious Adverse Events
All SAEs, regardless of their relationship to study treatment, must be reported on a 
completed SAE form by email or fax as soon as possible but no later than 1 business 
day from the date the investigator becomes aware of the event.
SAEs, regardless of causality assessment, must be collected through the through the last visit
and for 28 days after the subject’s last dose.  All SAEs must be followed to resolution or, if 
resolution is unlikely, to stabilization.  Any SAE judged by the investigator to be related to 
the study treatment or any protocol-required procedure should be reported to the sponsor 
regardless of the length of time that has passed since study completion.
The detailed contact information for reporting of SAEs is provided in the Investigator Study 
File.
For urgent safety issues, please ensure all appropriate medical care is administered to the 
subject and contact the appropriate study team member listed in the Investigator Study File.
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report.  This includes the investigator’s assessment of causality.
Any follow-up information received on SAEs should be forwarded within 1 business day of 
its receipt.  If the follow-up information changes the investigator’s assessment of causality, 
this should also be noted on the follow-up SAE form.
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested by 
the sponsor.
The investigator must notify his/her IRB/IEC of the occurrence of the SAE, in writing, if 
required by their institution.  A copy of this communication must be forwarded to the sponsor 
to be filed in the sponsor’s Trial Master File.
9.5.4.2
Reporting of Pregnancy and Exposure to Study Drug through Breastfeeding
Any pregnancy in which the estimated date of conception is either before the last visit or 
within 30 days of last study treatment or any exposure to study drug through breastfeeding 
during study treatment or within 30 days of last study treatment must be reported.
If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, this 
should be reported regardless of the length of time that has passed since the exposure to study 
treatment.

A congenital anomaly, death during perinatal period, an induced abortion, or a spontaneous 
abortion are considered to be an SAE and should be reported in the same time frame and in 
the same format as all other SAEs (see Section 9.5.4.1).
Pregnancies or exposure to study drug through breastfeeding must be reported by fax or 
email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy.  The contact information for the reporting of pregnancies 
and exposure to study drug through breastfeeding is provided in the Investigator Study File.  
The Pregnancy Report Form must be used for reporting.  All pregnancies must be followed to 
outcome.  The outcome of the pregnancy must be reported as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the outcome.
A subject who becomes pregnant must be withdrawn from the study. 
9.5.4.3
Reporting of Events Association with Special Situations
9.5.4.3.1 REPORTING OF ADVERSE EVENTS ASSOCIATED WITH STUDY DRUG OVERDOSE,
MISUSE, ABUSE, OR MEDICATION ERROR
Adverse events associated with study drug overdose, misuse, abuse, and medication error 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication error are defined as follows:
Overdose
Accidental or intentional use of the study drug in an amount higher
than the protocol-defined dose
Misuse
Intentional and inappropriate use of study drug not in accordance with 
the protocol or authorized dose, route of administration, or 
indication(s) or use of prescription-only study drug without a 
prescription
Abuse
Sporadic or persistent intentional excessive use of study drug 
accompanied by harmful physical or psychological effects
Medication error
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of the 
healthcare professional, subject, or consumer.  Such events may be 
related to professional practice, healthcare products, occupational 
exposure, procedures, or
systems,
including prescribing,
order 
communication,
product
labeling, 
packaging, 
nomenclature,
compounding,
dispensing,
distribution,
administration, education,
monitoring, or use.
All AEs associated with overdose, misuse, abuse, or medication error should be captured on 
the Adverse Event CRF and also reported using the procedures detailed in Section 9.5.4.1
even if the AEs do not meet serious criteria.  Abuse is always to be captured as an AE.  If the

Eisai
FINAL (v3.0):  14 Sep 2016
Confidential
Page 58 of 85
AE associated with an overdose, misuse, abuse, or medication error does not meet serious 
criteria, it must still be reported using the SAE form and in an expedited manner but should 
be noted as nonserious on the SAE form and the Adverse Event CRF.
9.5.4.3.2 REPORTING OF STUDY-SPECIFIC EVENTS
Study-specific events (listed below) should always be considered as serious important 
medical events and be entered on the Adverse Event CRF and reported using the procedures 
detailed in Reporting of Serious Adverse Events (Section 9.5.4.1), even if the study-specific 
event does not meet other serious criteria.  

Serotonin syndrome
Must have at least 1 of the following: spontaneous clonus; 
inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus

Psychosis

Suicidal behavior 

Priapism

New onset of valvular heart disease

New onset pulmonary hypertension

Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas 
of the skin

Fibroadenomas of the breast or ductal carcinoma in situ
The following additional study specific AE of interest should be reported using the 
procedures detailed in Reporting of SAEs (Section 9.5.4.1), even if the study-specific 
event does not meet serious criteria.  If the event meets seriousness criteria, it should 
be reported as an SAE as above.  However, if the event listed below does not meet 
serious criteria, it should be noted as nonserious on the Adverse Event CRF:  

Suicidal ideation

Euphoria 
9.5.4.4
Expedited Reporting
The sponsor must inform investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (ie, within 
specific time frames).  For this reason, it is imperative that sites provide complete SAE 
information in the manner described above.
9.5.4.5
Breaking the Blind
In the case of a medical emergency where the appropriate treatment of the subject requires 
knowledge of the study treatment given, the investigator may break the randomization code 
Page 709 of 897

Clinical Study Protocol

Eisai
FINAL (v3.0):  14 Sep 2016

for an individual subject.  In all such cases, the AE necessitating the emergency blind break 
will be handled as an SAE in accordance with the procedures indicated above.  Any broken 
code will be clearly justified and documented.  The medical monitor must be notified 
immediately of the blind break.
9.5.4.6
Regulatory Reporting of Adverse Events
Adverse events will be reported by the sponsor or a third party acting on behalf of the 
sponsor to regulatory authorities in compliance with local and regional law and established 
guidance.  The format of these reports will be dictated by the local and regional 
requirements.
9.5.5
Completion/Discontinuation of Subjects
The investigator may withdraw the subject from the study at any time for safety or 
administrative reasons.  A subject may elect to discontinue the study at any time for any 
reason.  All subjects will continue in the study until the 52-week evaluation is completed.  
Subjects who discontinue treatment prematurely will be followed up until study completion.  
All subjects who discontinue the study are to complete the study’s early discontinuation 
procedures indicated in the Schedule of Procedures/Assessments (Table 2).
The investigator will promptly explain to the subject involved that the study will be 
discontinued for that subject and provide appropriate medical treatment and other necessary 
measures for the subject.  A subject who has ceased to return for visits will be followed up by 
mail, phone, or other means to gather information such as the reason for failure to return, the 
status of treatment compliance, the presence or absence of AEs, and clinical courses of signs 
and symptoms.
Subjects who discontinue early from the study will be discontinued for 1 of these primary 
reasons: AE(s), lost to follow-up, subject choice, withdrawal of consent, pregnancy, study 
terminated by sponsor, or other.  In addition to the primary reason, the subject may indicate
1 or more of secondary reasons for discontinuation.  Study disposition information will be 
collected on the Subject Disposition CRF.
Detailed retention strategies will be developed and included in study manual. These include 
a highly trained and competent staff, easy access to the clinic, reminder and follow-up calls, 
interactive group sessions with games and hands-on nutrition and physical activity 
demonstrations, random raffle drawings, social events, birthday and holiday cards, and
newsletters. In addition, home visits for assessments of families will be an option, as needed, 
to maximize data collection. This detailed retention plan will help prevent missing data.
A subject removed from the study for any reason may not be replaced.
9.5.6
Abuse or Diversion of Study Drug
During the study, the investigator will report any concern about abuse or diversion of study 
drugs by completing the Abuse or Diversion of Study Drug CRF.  The DEA Registrant has

the responsibility to comply with local, state, and Federal laws to notify the Field Division 
Office of the DEA of any theft or significant loss of any controlled substances upon 
discovery of such theft or loss.
9.5.7
Confirmation of Medical Care by Another Physician
The investigator will instruct subjects to inform site personnel when they are planning to 
receive medical care by another physician.  At each visit, the investigator will ask the subject 
whether he or she has received medical care by another physician since the last visit or is 
planning to do so in the future.  When the subject is going to receive medical care by another 
physician, the investigator, with the consent of the subject, will inform the other physician 
that the subject is participating in the clinical study.

Data Quality Assurance
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines.  Site audits 
will be made periodically by the sponsor’s or the CRO’s qualified compliance auditing team, 
which is an independent function from the study team responsible for conduct of the study.
9.6.1
Data Collection
Data required by the protocol will be collected on the CRFs and entered into a validated data 
management system that is compliant with all regulatory requirements.  As defined by ICH 
guidelines, the CRF is a printed, optical, or electronic document designed to record all of the 
protocol-required information to be reported to the sponsor on each study subject.
Data collection on the CRF must follow the instructions described in the CRF Completion 
Guidelines.  The investigator has ultimate responsibility for the collection and reporting of all 
clinical data entered on the CRF.  The investigator or designee as identified on Form 
FDA 1572 must sign the completed CRF to attest to its accuracy, authenticity, and 
completeness.
Completed, original CRFs are the sole property of Eisai and should not be made available in 
any form to third parties without written permission from Eisai, except for authorized 
representatives of Eisai or appropriate regulatory authorities.
9.6.2
Clinical Data Management
All software applications used in the collection of data will be properly validated following 
standard computer system validation that is compliant with all regulatory requirements.  All 
data, both CRF and external data (eg, laboratory data), will be entered into a clinical system.

Demographic and Other Baseline Characteristics
Demographic and other baseline characteristics for the FAS and Safety Analysis Sets will be 
summarized for each treatment group using descriptive statistics or frequency count.  
Continuous demographic and baseline variables include age, height, BMI, waist 
circumference, and weight; categorical variables include sex and race.
9.7.1.5

All investigator terms for medications recorded in the CRF will be coded to an 11-digit 
character code using the World Health Organization Drug Dictionary.  The number 
(percentage) of subjects who took prior and concomitant medications will be summarized for
the Safety Analysis Set by treatment group, Anatomical Therapeutic Chemical class, and 
World Health Organization Drug Dictionary preferred term (PT).  Prior medications will be 
defined as medications that stopped before the first dose of study drug.  Concomitant 
medications will be defined as medications that started on or after the date of the dosing of 
study drug and continued up to 30 days afterward.
9.7.1.6
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, while the PP will 
be used as a supportive analysis.  Unless specified otherwise, a 2-sided α=0.05 significance 
level will be used for all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change 
from baseline in BMI will be analyzed using the mixed effect model repeated measurement 
analysis (MMRM) assuming the missing data is missing at random (MAR) with factors of 
treatment, visits (Baseline, Week 1, 5, 8, 12, 20, 28, 36, 44, and 52), age group (9 to 11 years 
old and 12 to 17 years old), sex (male and female), treatment-by-visit interaction as fixed 
effect, subjects as random effect, and the baseline BMI as a covariate.  The unstructured 
covariance matrix will be used in the analysis and the treatment comparison at Week 52 will 
be the event of interest.  In case of a convergence issue, the Toeplitz covariance structure will 
be used in the model.
Subgroup analyses and additional sensitivity analyses will be performed as appropriate 
including multiple imputation methods assuming the missing values are MAR and missing 
not at random (MNAR) to handle missing data.
The following analyses will be considered as sensitivity analyses:

PP analysis: The same primary efficacy analyses described above will be repeated 
based on the PP.

Multiple imputation (MI): the same primary efficacy analyses described above will 
be analyzed using MI for impute the missing data, assuming the missing values are 
MAR and MNAR.


Change from baseline in standardized BMI score (Z-score):
The same primary 
efficacy analyses described above will be repeated using Z-score.
Additional sensitivity analyses may also be explored and described in the SAP, if deemed 
appropriate.  
Key Secondary Efficacy Analysis
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 
5% BMI reduction at Week 52.  The secondary efficacy endpoint will be analyzed only if the 
test for the primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be 
analyzed using a logistic regression model with factors of treatment, age group (9 to 11 years 
old and 12 to 17 years old) and sex (male and female), and baseline BMI as a covariate using 
FAS.  Subjects with any missing assessment at Week 52 will be considered as treatment 
failures in this analysis.
Other Secondary Efficacy Analyses
Unless specified, for all other secondary efficacy endpoints, the continuous variables will be 
analyzed using MMRM and categorical variables will be analyzed using the Cochran Mantel 
Haenszel test, Chi-square test, or logistic regression as appropriate.  Additional analysis may
be performed as needed using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including age group 
(9 to 11 years old and 12 to 17 years old), sex (male and female), race (white, black, Asian,
and other). Additional subgroups may be explored, if deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and 
sensitivity analyses.
9.7.1.7
Pharmacokinetic, Pharmacodynamic, Pharmacogenomic, and Other Biomarker
Analyses
9.7.1.7.1 PHARMACOKINETIC ANALYSES
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling.  The effect of covariates, such as baseline characteristics
or demographics, on PK will be explored.  Derived exposure parameters such as the 
maximum observed concentration and the area under the concentration-time curve from time
0 to 24 hours at steady-state will be calculated from the final PK model using individual 
posterior estimates of the PK parameters and from dosing history.  The PK analysis set will 
be used for this analysis.

9.7.1.7.2 PHARMACODYNAMIC ANALYSES
Change from Baseline in BMI will be assessed as the PD analysis.  The PD analysis set will 
be used for this analysis.
Other assessments (eg, percentage of BMI change, proportion [%] of patients achieving ≥5% 
and ≥10% BMI reduction, and change in waist circumference from baseline) will also 
assessed as part of the PD analysis.  The PK/PD analysis set will be used for this analysis.
9.7.1.7.3 PHARMACOKINETIC/PHARMACODYNAMIC ANALYSES
Population PK/PD modeling will be used to explore the relationship between lorcaserin 
plasma exposure and response, including but not limited to change in BMI from baseline and 
the probability of achieving at least a 5% and at least a 10% change in BMI from baseline to 
Week 52.  Additionally, exposure-safety relationships for select safety parameters may be 
explored graphically, depending on the data at the end of study.  Any emergent relationship 
may be modeled as appropriate.  Any parameters based on the study data may be considered 
for exploratory assessment for its relationship to PK.
9.7.1.7.4 PHARMACOGENOMIC AND PHARMACOGENETIC ANALYSES
Not applicable
9.7.1.8
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments 
including the incidence of AEs (including changes from baseline in physical examination), 
growth (CDC growth chart and bone age determined by x-ray of the hand), sexual maturation 
(Tanner Staging), out-of-normal-range laboratory safety test values, change from baseline in 
laboratory safety test values (including biomarkers), ECGs, and vital sign measurements will 
be summarized by treatment group using descriptive statistics or frequency count as 
appropriate.  In addition, suicidal ideation, cognitive function, behavior, and mood will be 
evaluated by the C-SSRS, WRAML-2, CDI-2, and C-SSRS, respectively, and will also be 
summarized by treatment group using descriptive statistics or frequency count as appropriate.  
All WRAML-2 raw scores from the Core Battery will be converted to age and gender 
standard scores for purposes of intra individual comparisons
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
9.7.1.8.1 EXTENT OF EXPOSURE
Subjects will receive Belviq XR 20 mg or placebo QD for up to 52 weeks. The extent of 
exposure will be characterized by duration of exposure (in weeks) for each treatment group.
Duration of exposure will be defined as the number of weeks between the date the subject 
received the 1st dose of study drug and the date the subject received the last dose of study

drug.  Duration of exposure will be summarized using descriptive statistics by treatment 
group.  In addition, the duration of exposure will be categorized and will be summarized 
using frequency count by treatment group.
9.7.1.8.2 ADVERSE EVENTS
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities 
(MedDRA).  Adverse events will be coded to the MedDRA (Version 18.0 or higher) lower 
level term closest to the verbatim term.  The linked MedDRA PT and primary system organ 
class (SOC) are also captured in the database.
A treatment-emergent AE (TEAE) is defined as an AE that emerges during treatment (up to 
28 days after the last dose of study drug), having been absent at pretreatment (Baseline) or 
•
Reemerges during treatment (up to 28 days after the last dose of study drug), having been 
present at pretreatment (Baseline) but stopped before treatment, or 
•
Worsens in severity during treatment relative to the pretreatment state, when the AE is 
continuous.
Only those AEs that were treatment emergent will be included in summary tables.  All AEs, 
treatment emergent or otherwise, will be presented in subject data listings.
The TEAEs will be summarized by treatment group.  The following summaries will be 
reported for TEAES:

Incidence of TEAEs in descending order of frequency

Incidence of TEAEs by SOC and PT

Incidence of treatment-related TEAEs by SOC and PT

Incidence of TEAEs by SOC, PT and maximum severity (mild, moderate, or severe)

Incidence of treatment-related TEAEs by SOC, PT, and maximum severity (mild, 
moderate, or severe)

Incidence of TEAEs by SOC, PT, and relationship to study drug (Yes [related] or No 
[not related]) 
A subject will be counted only once within a SOC or PT, if the subject experienced more 
than 1 TEAE within a specified SOC and PT.


Incidence of treatment-emergent SAE by SOC and PT

Incidence of treatment-related treatment-emergent SAE by SOC and PT
In addition, subjects with TEAEs leading to discontinuation from study drug and AEs of 
special interest as described in Section 9.5.4.3.2 will be summarized by MedDRA SOC and 
PT for each treatment group. 
9.7.1.8.3 LABORATORY VALUES
Laboratory results will be summarized using Système International units, as appropriate.  For 
all quantitative parameters listed in Section 9.5.1.5.3, the actual value and the change from 
baseline to each postbaseline visit and to the end of treatment (defined as the last 
on-treatment value) will be summarized by visit and treatment group using descriptive 
statistics.  Percentages will be based on the number of subjects with both nonmissing 
baseline and relevant postbaseline results.
Laboratory test results will be assigned a low/normal/high (LNH) classification according to 
whether the value was below (L), within (N), or above (H) the laboratory parameter’s 
reference range.  Within-treatment comparisons for each laboratory parameter will be based 
on 3-by-3 tables (shift tables) that compare the baseline LNH classification to the LNH 
classification at the End of Treatment and the Follow-Up visits.  Similar shift tables will also 
compare the baseline LNH classification to the LNH classification for the highest and lowest 
value during the treatment period.
Appendix 1
presents the criteria that will be used to identify subjects with 
treatment-emergent markedly abnormal laboratory values (TEMAV).  Except for phosphate, 
a TEMAV is defined as a postbaseline value with an increase from baseline to a grade of 2 or 
higher.  For phosphate, a TEMAV was defined as a postbaseline value with an increase from 
baseline to a grade of 3 or higher.  When displaying the incidence of TEMAVs, each subject 
may be counted once in the laboratory parameter high and in the laboratory parameter low 
categories, as applicable.
9.7.1.8.4 VITAL SIGNS
Descriptive statistics for vital signs parameters (eg, systolic and diastolic BP, pulse, 
respiratory rate, temperature, weight) and changes from baseline will be presented by visit
and treatment group.

9.7.1.8.5 ELECTROCARDIOGRAMS
For each ECG parameter (including PR interval, RR interval, QRS interval, QT interval, QTc
interval (Bazett formula), QTc interval (Fridericia formula), and heart rate), the actual value 
and change from baseline will be summarized by visit and treatment group using descriptive 
statistics. 
Shift tables will present changes from baseline in ECG interpretation (categorized as normal; 
abnormal, not clinically significant; and abnormal, clinically significant) to end of treatment. 
Maximum postbaseline QTc (Bazett) and QTc (Fridericia) will also be tabulated by treatment 
group as follows:

Number (percentage) of subjects in greater than 450 msec, greater than 480 msec, and 
greater than 500 msec during the treatment, and

Number (percentage) of subjects with an increment of greater than 30 msec and 
greater than 60 msec from the baseline visit.
9.7.1.8.6 OTHER SAFETY ANALYSES
Other safety assessments including children and adolescent growth evaluations using CDC 
growth chart and bone age using x-ray of the hand, sexual maturation as measured in Tanner 
Staging, neuromuscular sign assessment for serotonin syndrome, signs and symptoms of 
priapism and prolactinemia, study drug effect on cognitive function assessed by WRAML-2, 
assessment of suicidality using C-SSRS, and mood assessment using CDI-2 will be also be 
summarized by treatment group at each scheduled visit.
9.7.2
Determination of Sample Size
The proposed sample size is based on the comparison of the primary efficacy endpoint, 
change from Baseline in BMI at Week 52 between the Belviq XR 20-mg treatment group and 
placebo group.  Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 
360 subjects in a 1:1 ratio (n=180 in the Belviq XR 20-mg treatment group; n=180 in the 
placebo group) will have at least 90% power to detect a treatment difference of 1 kg/m2 in 
BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at 
least a 5% BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, 
this sample of 360 subjects (180 subjects for Belviq XR 20 mg and 180 subjects for placebo) 
will also have greater than 85% power to detect an absolute difference of 20% between the 
Belviq XR 20-mg group and placebo group, using a 2-sided Fisher’s Exact test with α=0.05.  
The assumption used in the sample size calculation is based on the 2 pivotal lorcaserin 
studies, APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.

11 PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE 
PROCEDURES)
11.1
Changes to the Protocol
Any change to the protocol requires a written protocol amendment or administrative change 
that must be approved by the sponsor before implementation.  Amendments specifically 
affecting the safety of subjects, the scope of the investigation, or the scientific quality of the 
study require submission to health or regulatory authorities as well as additional approval by 
the applicable IRBs/IECs.  These requirements should in no way prevent any immediate 
action from being taken by the investigator, or by the sponsor, in the interest of preserving 
the safety of all subjects included in the study.  If the investigator determines that an 
immediate change to or deviation from the protocol is necessary for safety reasons to 
eliminate an immediate hazard to the subjects, the sponsor’s medical monitor and the 
IRB/IEC for the site must be notified immediately.  The sponsor must notify the health or 
regulatory authority as required per local regulations.
Protocol amendments that affect only administrative aspects of the study may not require 
submission to health or regulatory authority or the IRB/IEC, but the health or regulatory 
authority and IRB/IEC should be kept informed of such changes as required by local 
regulations.  In these cases, the sponsor may be required to send a letter to the IRB/IEC and 
the Competent Authorities detailing such changes.
11.2
Adherence to the Protocol
The investigator will conduct the study in strict accordance with the protocol (refer to ICH 
E6, Section 4.5).
11.3
Monitoring Procedures
The sponsor’s/CRO’s CRA will maintain contact with the investigator and designated staff 
by telephone, letter, or email between study visits.  Monitoring visits to each site will be 
conducted by the assigned CRA as described in the monitoring plan.  The investigator will 
allow the CRA to inspect the clinical, laboratory, and pharmacy facilities to assure 
compliance with GCP and local regulatory requirements.  The CRFs and subject’s 
corresponding original medical records (source documents) are to be fully available for 
review by the sponsor’s representatives at regular intervals.  These reviews verify adherence 
to study protocol and data accuracy in accordance with local regulations.  All records at the 
site are subject to inspection by the local auditing agency and IRB/IEC review.

A CRF is required and must be completed for each subject by qualified and authorized 
personnel.  All data on the CRF must reflect the corresponding source document, except 
when a section of the CRF itself is used as source document.  Any correction to entries made 
on the CRF must be documented in a valid audit trail where the correction is dated, the 
individual making the correct is identified, the reason for the change is stated, and the 
original data are not obscured.  Only data required by the protocol for the purposes of the 
study should be collected.
The investigator must sign each CRF.  The investigator will report the CRFs to the sponsor 
and retain a copy of the CRFs.
11.5
Identification of Source Data
All data to be recorded on the CRF must reflect the corresponding source documents.

11.6
Retention of Records
The circumstances of completion or termination of the study notwithstanding, the 
investigator is responsible for retaining all study documents, including but not limited to the 
protocol, copies of CRFs, the Investigator's Brochure, and regulatory agency registration 
documents (eg, Form FDA 1572 ICFs, and IRB/IEC correspondence).  In addition, the 
sponsor will send a list of treatment codes by study subject to the investigator after the 
clinical database for this study has been locked.  The site should plan to retain study 
documents, as directed by the sponsor, for at least 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region or at least 3 years have elapsed since the formal 
discontinuation of clinical development of the investigational product.
It is requested that at the completion of the required retention period, or should the 
investigator retire or relocate, the investigator contact the sponsor, allowing the sponsor the 
option of permanently retaining the study records.
11.7
Auditing Procedures and Inspection
In addition to the routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of ICH GCP and all applicable local 
regulations.  If a government regulatory authority requests an inspection during the study or 
after its completion, the investigator must inform the sponsor immediately.
11.8
Handling of Study Drug
All study drugs will be supplied to the PI (or a designated pharmacist) by the sponsor.  Drug 
supplies must be kept in an appropriate secure area (eg, locked cabinet) and stored according 
to the conditions specified on the drug labels.  Investigational product will be stored in 
accordance with the DEA Regulations for Scheduled III - V Drugs and labeled storage 
conditions.  The investigator (or a designated pharmacist) must maintain an accurate record 
of the shipment and dispensing of the study drug in a drug accountability ledger, a copy of 
which must be given to the sponsor at the end of the study.  An accurate record of the date 
and amount of study drug dispensed to each subject must be available for inspection at any 
time.  The CRA will visit the site and review these documents along with all other study 
conduct documents at appropriate intervals once study drug has been received by the site.
All drug supplies are to be used only for this study and not for any other purpose.  The 
investigator (or site personnel) must not destroy any drug labels or any partly used or unused 
drug supply before approval to do so by the sponsor.  At the conclusion of the study and as 
appropriate during the study, the investigator (or a designated pharmacist) will return all used 
and unused drug containers, drug labels, and a copy of the completed drug disposition form 
to the sponsor’s CRA.

Publication of Results
All manuscripts, abstracts, or other modes of presentation arising from the results of the 
study must be reviewed and approved in writing by the sponsor in advance of submission 
pursuant to the terms and conditions set forth in the executed Clinical Trial Agreement 
between the sponsor/CRO and the institution/investigator.  The review is aimed at protecting 
the sponsor's proprietary information existing either at the date of the commencement of the 
study or generated during the study.
The detailed obligations regarding the publication of any data, material results, or other 
information, generated or created in relation to the study shall be set out in the agreement 
between each investigator and the sponsor or CRO, as appropriate.
11.10 Disclosure and Confidentiality
The contents of this protocol and any amendments and results obtained during the study 
should be kept confidential by the investigator, the investigator’s staff, and the IRB/IEC and 
will not be disclosed in whole or in part to others, or used for any purpose other than 
reviewing or performing the study, without the written consent of the sponsor.  No data 
collected as part of this study will be used in any written work, including publications, 
without the written consent of the sponsor.  These obligations of confidentiality and non-use 
shall in no way diminish such obligations as set forth in either the Confidentiality Agreement 
or 
Clinical 
Trial 
Agreement 
executed 
between 
the 
sponsor/CRO 
and 
the 
institution/investigator.
All persons assisting in the performance of this study must be bound by the obligations of 
confidentiality and non-use set forth in either the Confidentiality Agreement or Clinical Trial 
Agreement executed between the institution/investigator and the sponsor/CRO.
11.11 Discontinuation of Study
The sponsor reserves the right to discontinue the study for medical reasons or any other 
reason at any time.  If a study is prematurely terminated or suspended, the sponsor will 
promptly inform the investigators/institutions and regulatory authorities of the termination or 
suspension and the reason(s) for the termination or suspension.  The IRB/IEC will also be 
informed promptly and provided the reason(s) for the termination or suspension by the 
sponsor or by the investigator/institution, as specified by the applicable regulatory 
requirement(s).
The investigator reserves the right to discontinue the study should his/her judgment so 
dictate.  If the investigator terminates or suspends a study without prior agreement of the 
sponsor, the investigator should inform the institution where applicable, and the 
investigator/institution should promptly inform the sponsor and the IRB/IEC and provide the 
sponsor and the IRB/IEC with a detailed written explanation of the termination or 
suspension.  Study records must be retained as noted above.

Family-Based Lifestyle Program
Program Overview
All subjects and their caregivers (participating parent or guardian) in Study 403 will 
participate in a standardized weight management program for adolescents consisting of 
multicomponent behavior therapy.  The therapy will focus on healthy eating, physical 
activity, and lifestyle changes that will facilitate weight loss and weight-loss maintenance. 
The role of the caregivers is to support their child or adolescents’ lifestyle changes and their 
taking of study medication.
The objectives of this program are as follows:

Develop a weight management program for all Belviq XR study participants and their
caregivers (caregivers are instructed in methods to support their adolescents’ progress
but caregivers are themselves not instructed to lose weight or take medication)

Standardize the weight management program across all study sites

Maximize participant retention

Promote participant’s adherence to both taking study medication and following the
lifestyle program

Appendix 3
Pharmacodynamic and Other Biomarker Research
Subjects enrolled in this clinical study will have biologic samples collected for 
pharmacodynamic (PD), and other biomarker analysis.  These samples may be used for 
discovery or validation to identify biomarkers that may be used for exploratory evaluation of 
response or safety-related outcomes as well as for use in diagnostic development.
The pharmacogenetics (PG) samples may be used to identify genetic factors that may 
influence a subject’s exposure to the study drug, as well as genetic factors that may have an 
effect on clinical response or potential adverse events (AEs) related to study treatment, and to 
explore the role of genetic variability in response.  Samples may be analyzed to determine a 
subject’s genotypes or sequence for a number of genes or non-coding regulatory regions.  
The research may include the investigation of polymorphisms in genes that are likely to 
influence the study drug pharmacokinetic (PK) or therapeutic response.
Collection of the PD, and other biomarker samples will be bound by the sample principles 
and processes outlined in the main study protocol.  Sample collection for PD, PG, and other 
biomarker analysis is required as per the study protocol unless the collection and use of the 
samples is prohibited by specific country laws.
Sample Collection and Handling
The samples will be collected according to the study flow chart.  If, for operational or 
medical reasons, the genomic DNA blood sample cannot be obtained at the prespecified visit, 
the sample can be taken at any study center visit at the discretion of the investigator and site 
staff.
Security of the Samples, Use of the Samples, Retention of the Samples
Sample processing, for example DNA or RNA extraction, genotyping, sequencing, or other 
analysis will be performed by a laboratory under the direction of the sponsor.  Processing, 
analysis, and storage will be performed at a secure laboratory facility to protect the validity 
of the data and maintain subject privacy.
Samples will only be used for the purposes described in this protocol.  Laboratories 
contracted to perform the analysis on behalf of the sponsor will not retain rights to the 
samples beyond those necessary to perform the specified analysis and will not transfer or sell 
those samples.  The sponsor will not sell the samples to a third party.
Samples will be stored for up to 15 years after the completion of the study (defined as 
submission of the clinical study report to the appropriate regulatory agencies).  At the end of 
the storage period, samples will be destroyed.  Samples may be stored longer if a health 
authority (or medicinal product approval agency) has active questions about the study.  In 
this special circumstance, the samples will be stored until the questions have been adequately 
addressed.

It is possible that future research and technological advances may identify genomic variants 
of interest, or allow alternative types of genomic analysis not foreseen at this time.  Because 
it is not possible to prospectively define every avenue of future testing, all samples collected 
will be single or double coded (according to the ICH E15 guidelines) in order to maintain 
subject privacy.
Right to Withdraw
If, during the time the samples are stored, a participant would like to withdraw his/her 
consent for participation in this research, Eisai will destroy the samples.  Information from 
any assays that have already been completed at the time of withdrawal of consent will 
continue to be used as necessary to protect the integrity of the research project.
Subject Privacy and Return of Data
No subject-identifying information (eg, initials, date of birth, government identifying 
number) will be associated with the sample.  All PD and other biomarker samples will be 
single coded.  Genomic DNA samples used to explore the effects on PK, treatment response, 
and safety will be single coded.  Genomic DNA samples that will be stored for long-term use 
(defined as 15 years after the completion of the study) will be double coded.  Double coding 
involves removing the initial code (subject ID) and replacing with another code such that the 
subject can be re-identified by use of 2 code keys.  The code keys are usually held by 
different parties.  The key linking the sample ID to the subject number will be maintained 
separately from the sample.  At this point, the samples will be double-coded, the first code 
being the subject number.  Laboratory personnel performing genetic analysis will not have 
access to the “key.”  Clinical data collected as part of the clinical trial will be cleaned of 
subject identifying information and linked by use of the sample ID “key.”
The sponsor will take steps to ensure that data are protected accordingly and confidentiality 
is maintained as far as possible.  Data from subjects enrolled in this study may be analyzed 
worldwide, regardless of location of collection.
The sponsor and its representatives and agents may share coded data with persons and 
organizations involved in the conduct or oversight of this research.  These include:
•
Clinical research organizations retained by the sponsor
•
Independent ethics committees or institutional review boards that have responsibility for
this research study
•
National regulatory authorities or equivalent government agencies
At the end of the analysis, results may be presented in a final report which can include part or 
all of the coded data, in listing or summary format.  Other publication (eg, in peer-reviewed 
Page 733 of 897

Eisai

Page 83 of 85
scientific journals) or public presentation of the study results will only include summaries of 
the population in the study, and no identified individual results will be disclosed.
Given the research nature of the PD, PG, and other biomarker analysis, it will not be possible 
to return individual data to subjects.  The results that may be generated are not currently 
anticipated to have clinical relevance to the patients or their family members.  Therefore, 
these results will not be disclosed to the patients or their physicians.
If at any time, PD, PG, or other biomarker results are obtained that may have clinical 
relevance, Institutional Review Board review and approval will be sought to determine the 
most appropriate manner of disclosure and to determine whether or not validation in a 
Clinical Laboratory Improvement Amendments-certified setting will be required.  Sharing of 
research data with individual patients should only occur when data have been validated by 
multiple studies and testing has been done in Clinical Laboratory Improvement 
Amendments-approved laboratories.

A single dose pharmacokinetic 
study in pediatric obese subjects 
(APD356-A001-026) indicated 
that patients with body weight 
greater than or equal to 60 kg 
can be administered a dose 
similar to that given to adults 
and adolescents.  Based on 
Centers for Disease Control and 
Prevention (CDC) growth chart 
data, almost all subjects over 
9 years of age are likely to be at 
or over 60 kg body weight.  
Therefore, children age 9 to 
11 years have been included in 
the current study.

Study Design
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in obese 
children and adolescents, ages 9 to 17 years.  Approximately 360 subjects will be randomized in a 
1:1 ratio to Belviq XR 20 mg QD (180 subjects) and placebo (180 subjects).  Subjects will be 
stratified by age group and sex.  At least 30% of the total subjects should be ages 9 to 11 years.  
Subjects will receive Belviq XR 20 mg or placebo QD in a 1:1 ratio for up to 52 weeks. Throughout 
the duration of the study, subjects will be encouraged to adhere to a lifestyle modification program 
that includes diet and exercise counseling.
The study will consist of 2 phases: Prerandomization and Randomization.  The Prerandomization 
Phase will last up to 30 days and consist of 1 visit during which subjects will be screened for 
eligibility.  The Randomization Phase consists of a Treatment Period and a Follow-Up Period.  The 
Treatment Period will last for a maximum of 52 weeks, with visits at Weeks 1, 5, 8, 12, 20, 28, 36,
44, and 52.  The Follow-Up Period will extend from the End of Treatment visit to the End of Study 
visit.
Subjects who screen fail can be re-screened only once after 60 days.  All subjects will continue in the 
study until the 52-week evaluation is completed.  Subjects who discontinue treatment prematurely 
will be followed up until study completion.  
Number of Subjects
Approximately 700 subjects will be screened to provide 360 randomized subjects.

Pharmacokinetic Assessments
Plasma lorcaserin concentrations will be measured at Weeks 12, 28, 36, and 52 for analysis of 
population PK.  At Weeks 12, 28, and 52, subjects will be instructed to take their morning dose at the 
clinic.  Two blood samples for determination of plasma concentrations of lorcaserin will be taken at 
each of these visits: within 30 minutes before dosing and within 1 to 3 hours after dosing.  At the 
Week 36 visit, subjects will take the morning dose at home, and 1 blood sample for determination of 
plasma concentrations of lorcaserin will be collected at the investigational site within 4 to 6 hours 
after dosing.
Pharmacodynamic Assessments

Change from baseline in BMI and body weight

Proportion (%) of patients achieving at least a 5% and at least a 10% reduction in BMI and 
body weight
Other PD endpoints will be considered based on the data at the end of the study to explore their 
relationships with lorcaserin plasma exposure.
Pharmacogenomic/Pharmacogenetic Assessments
Not applicable
Safety Assessments
Safety assessments will consist of monitoring and recording all adverse events (AEs) and serious 
adverse events (SAEs); electrocardiograms (ECGs); laboratory evaluation for hematology, thyroid 
function, adrenal function and biochemical blood and urine biomarkers of bone health; blood 
chemistry and urine values; neuropsychiatric events; periodic measurement of vital signs,
neuromuscular signs for screening potential serotonin syndrome, and signs or symptoms of priapism 
and prolactinemia; and performance of physical examinations.
In patients with potential 
prolactin-related AEs, such as galactorrhea, changes in libido, or changes to menstrual cycle, 
prolactin level will be measured and assessed.
Study drug effect on growth of children and 
adolescents will be evaluated using the CDC growth chart at Baseline, and Weeks 5, 12, 28, 36, 52, 
and at Follow-Up; a full physical examination, at Baseline, Weeks 12, 28, 52, and at Follow-Up; and 
bone age determination by x-ray of the hand at Baseline, Weeks 12, 28, and 52.
Children and 
adolescent sexual maturation will be evaluated by assessing sex hormones and self-reported changes 
in Tanner Staging at Baseline, Weeks 28 and 52, and at Follow-Up. Any subject with symptoms or 
signs of cardiac valvular disease or PH will be further evaluated by centralized echocardiogram
assessments.
The assessments will be adjudicated and be followed up by echocardiogram
assessments at end of the study.
The events of confirmed United States Food and Drug 
Administration (FDA) defined valvulopathy and PH will be captured in AE electronic Case Report 
Form (eCRF).
The (C-SSRS) will be used to assess all children and adolescents in the study for any signal of

Per-Protocol Analysis Set (PP) is the group of all randomized subjects who are 80% or greater 
compliant with study medication, completed the study, have no major protocol deviations, have 
no violations of inclusion or exclusion criteria, and have BMI data at Baseline and Week 52.  
The determination of subjects to be excluded from this population based on the above criteria 
and a list of major protocol violations will be included in the statistical analysis plan (SAP) and

parameter.

The PK Analysis Set is the group of all randomized subjects from whom at least 1 valid 
lorcaserin plasma concentration was obtained with associated documented dosing history.

The population PK/PD set is the group of randomized subjects with PK information and who 
have at least 1 adequately documented measurement of body weight.
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, and the PP will be used as 
a supportive analysis.  Unless otherwise specified, a 2-sided α=0.05 significance level will be used in 
all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change from 
baseline in BMI will be analyzed using the mixed effect model repeated measurement analysis 
(MMRM) with factors of treatment visits (Baseline, Week 1, 5, 8, 12, 20, 28, 36, 44, and 52), age 
group (9 to 11 years old and 12 to 17 years old), sex (male and female), treatment-by-visit interaction 
as fixed effect, subjects as random effect, and the baseline BMI as a covariate.  The unstructured 
covariance matrix will be used in the analysis and the treatment comparison at Week 52 will be the 
event of interest.  In case of a convergence issue, the Toeplitz covariance structure will be used in the 
model.
Subgroup analyses and additional sensitivity analyses will be performed as appropriate including 
multiple imputation methods assuming the missing values are missing at random (MAR) and missing 
not at random (MNAR) to handle missing data.
The following analyses will be considered as sensitivity analyses:

PP analysis: The same primary efficacy analyses described above will be repeated based on 
the PP.

Multiple imputation (MI):  the same primary efficacy analyses described above will be 
analyzed using MI for impute the missing data, assuming the missing values are MAR and 
MNAR.

Change from baseline in standardized BMI score (Z-score):  The same primary efficacy 
analyses described above will be repeated using Z-score.
Additional sensitivity analyses may also be explored and described in the SAP, if deemed 
appropriate.
Key Secondary Efficacy Analyses
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 5% BMI 
reduction at Week 52. The secondary efficacy endpoint will be analyzed only if the test for the 
primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be analyzed using 
a logistic regression model with factors of treatment, age group (9 to 11 years old and 12 to 17 years 
old), sex (male and female), and baseline BMI as a covariate using FAS.  Subjects with any missing 
assessment at Week 52 will be considered as treatment failures in this analysis.

Other Secondary Efficacy Analyses
In general, for all other secondary efficacy endpoints, the continuous variables will be analyzed using 
MMRM and categorical variables will be analyzed using the Cochran Mantel Haenszel test, 
Chi-square test, or logistic regression as appropriate.  Additional analysis may be performed as 
needed using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including age group (9 to 
11 years old and 12 to 17 years old), sex (male and female), and race (white, black, Asian, and other).  
Additional subgroups may be explored, if deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and sensitivity 
analyses.
Pharmacokinetic Analyses
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling. The effect of covariates such as baseline characteristics or 
demographics on PK will be explored. Derived exposure parameters such as the maximum observed 
concentration and the area under the concentration-time curve from time 0 to 24 hours at steady-state 
will be calculated from the final PK model using individual posterior estimates of the PK parameters 
and from dosing history. The PK analysis set will be used for this analysis.
Pharmacodynamic Analyses
Probability of achieving at least a 5% and at least a 10% body weight reduction and change from 
Baseline in body weight will be assessed as the PD analysis.  The PD analysis set will be used for this 
analysis.
Other assessments (eg, BMI change, percentage of BMI change, proportion [%] of patients achieving 
≥10% BMI reduction, and change in waist circumference from baseline) will also assessed as part of 
the PD analysis.  The PK/PD analysis set will be used for this analysis.
Pharmacokinetic/Pharmacodynamic Analyses
Population PK/PD modeling will be used to explore the relationship between lorcaserin plasma 
exposure and response, including but not limited to change in body weight from baseline and the 
probability of achieving at least a 5% and at least a 10% change in body weight from baseline to
Week 52.  Additionally, exposure-safety relationships for select safety parameters may be explored 
graphically depending on the data at the end of study.  Any emergent relationship may be modeled as 
appropriate.  Any parameters based on the study data may be considered for exploratory assessment 
for its relationship to PK.
Pharmacogenomic/Pharmacogenetic Analyses
Not applicable
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments including the 
incidence of AEs (including changes from baseline in physical examination), growth (CDC growth 
chart and bone age determined by x-ray of the hand), sexual maturation (Tanner Staging), 
out-of-normal-range laboratory safety test values, change from baseline in laboratory safety test 
values (including biomarkers), ECGs, and vital sign measurements will be summarized by treatment 
group using descriptive statistics or frequency count as appropriate.  In addition, suicidal ideation,

C-SSRS, respectively, and will also be summarized by treatment group using descriptive statistics or 
frequency count as appropriate. All WRAML-2 raw scores from the Core Battery will be converted 
to age and gender standard scores for purposes of intra individual comparisons
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.

Sample Size Rationale
The proposed sample size is based on the comparison of the primary efficacy endpoint, change in 
BMI from Baseline to Week 52 between the Belviq XR 20-mg treatment group and placebo group.  
Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 360 subjects in a 1:1 ratio 
(n=180 in the Belviq XR 20-mg treatment group; n=180 in the placebo group) will have at least 
90% power to detect a treatment difference of 1 kg/m2 in BMI, using a 2-sided t-test with α=0.05.  
Assuming the proportion of subjects achieving at least a 5% BMI reduction at Week 52 is 20% for 
the placebo group and a 40% dropout rate, this sample of 360 subjects (180 subjects for Belviq XR 
20 mg and 180 subjects for placebo) will also have greater than 85% power to detect an absolute 
difference of 20% between the Belviq XR 20-mg group and the placebo group, using a 2-sided 
Fisher’s Exact test with α=0.05. The assumption used in the sample size calculation is based on the 
2 pivotal lorcaserin studies APD356-009 and APD356-011 in obese and overweight non-diabetic 
adult subjects.

ETHICS
5.1
Institutional Review Boards/Independent Ethics Committees
The protocol, Informed Consent Form (ICF), and appropriate related documents must be 
reviewed and approved by an Institutional Review Board (IRB) or Independent Ethics 
Committee (IEC) constituted and functioning in accordance with International Conference on 
Harmonisation (ICH) Good Clinical Practice (ICH E6), Section 3, and any local regulations 
(eg, Federal Regulations, Title 21 Code of Federal Regulations [21 CFR] Part 56).  Any 
protocol amendment or revision to the ICF will be resubmitted to the IRB/IEC for review and 
approval, except for changes involving only logistical or administrative aspects of the study 
(eg, change in clinical research associate [CRA], change of telephone number[s]).  
Documentation of IRB/IEC compliance with the ICH E6 and any local regulations regarding 
constitution and review conduct will be provided to the sponsor.
A signed letter of study approval from the IRB/IEC chairman must be sent to the principal 
investigator (PI) with a copy to the sponsor before study start and the release of any study 
drug to the site by the sponsor or its designee (ICH E6, Section 4.4).  If the IRB/IEC decides 
to suspend or terminate the study, the investigator will immediately send the notice of study 
suspension or termination by the IRB/IEC to the sponsor.
Study progress is to be reported to IRB/IECs annually (or as required) by the investigator or 
sponsor, depending on local regulatory obligations.  If the investigator is required to report to 
the IRB/IEC, he/she will forward a copy to the sponsor at the time of each periodic report.  
The investigator(s) or the sponsor will submit, depending on local regulations, periodic 
reports and inform the IRB/IEC of any reportable adverse events (AEs) per ICH guidelines 
and local IRB/IEC standards of practice.  Upon completion of the study, the investigator will 
provide the IRB/IEC with a brief report of the outcome of the study, if required.
At the end of the study, the sponsor should notify the IRB/IEC and Competent Authority 
within 90 days.  The end of the study will be the date of the last study visit for the last subject 
in the study.  The sponsor should also provide the IRB/IEC with a summary of the study’s 
outcome.
In the case of early termination or a temporary halt of the study, the investigator should 
notify the IRB/IEC and Competent Authority within 15 calendar days, and a detailed written 
explanation of the reasons for the termination/halt should be given.

clinical studies, including Part 50 and Part 56 concerning informed subject consent 
and IRB regulations and applicable sections of US 21 CFR Part 312
5.3
Subject Information and Informed Consent
As part of administering the informed consent document, the investigator must explain to 
each subject and guardian/legally authorized representative the nature of the study, its 
purpose, the procedures involved, the expected duration, the potential risks and benefits 
involved, any potential discomfort, potential alternative procedure(s) or course(s) of 
treatment available to the subject, and the extent of maintaining confidentiality of the 
subject’s records.  Each subject must be informed that participation in the study is voluntary, 
that he/she may withdraw from the study at any time, and that withdrawal of consent will not 
affect his/her subsequent medical treatment or relationship with the treating physician.
This informed consent should be given by means of a standard written statement, written in 
nontechnical language.  The subject or the subject’s legally acceptable representative should 
understand the statement before signing and dating it and will be given a copy of the signed 
document.  If a subject is unable to read or if a legally acceptable representative is unable to 
read, an impartial witness should be present during the entire informed consent discussion.  
After the ICF and any other written information to be provided to subjects is read and 
explained to the subject or the subject’s legally acceptable representative, and after the 
subject or the subject’s legally acceptable representative has orally consented to the subject’s 
participation in the study and, if capable of doing so, has signed and personally dated the 
ICF, the witness should sign and personally date the consent form.  The subject will be asked 
to sign an ICF before any study-specific procedures are performed.  No subject can enter the 
study before his/her informed consent has been obtained.  The adolescent participant will 
provide written assent and the caregiver/guardian will provide written informed consent.
An unsigned copy of an IRB/IEC-approved ICF must be prepared in accordance with 
ICH E6, Section 4, and all applicable local regulations (Federal Regulations, 
Title 21 CFR Part 50, for studies in the United States).  Each subject must sign an approved

INTRODUCTION
7.1
Indication
Obesity
Obesity has become a global epidemic in western civilization, causing a serious public health 
concern.  In the United States, the prevalence of obesity in adolescents ages 12 and 19 years
has almost doubled over the past 2 decades.  The rate increased from 10.5% between 1988 
and 1994 to 20.5% between 2011 and 2012 (CDC/NCHS, 2013).  The prevalence of obesity 
in children in United States is also high.  The United States Centers for Disease Control and 
Prevention (CDC) reported in 2012 that 17.7% of children ages 6 to 11 years are obese.
Obesity in children and adolescents, defined in the United States as greater than or equal to 
the 95th percentile in gender- and age-specific body mass index (BMI), continues to grow at 
an alarming rate in the United States and globally.  Based on data (Wang and Lobstein, 2006) 
using various criteria for the definition of obesity that included more than 30 countries in 
Europe, North America, Asia, and the West Pacific, prevalence of obesity in these countries 
has also increased significantly, at a rate comparable to that in the United States.
Childhood and adolescent obesity has many negative implications for both the health and 
well-being of the individual as well as for society.  These include increased susceptibility to a 
host of diseases, chronic health disorders, psychological disorders, and premature death 
(Flegal, et al., 2005; Rofey, et al., 2009).  Increases in the prevalence of overweight and 
obese adolescents may result in a decrease in life expectancy for the 1st time in 200 years
(Peeters , et al, 2003).
As a result, there is a significant impact on the cost of healthcare.  It is estimated that medical 
costs due to overweight adolescents are approximately $14 billion per year in the United 
States (Trasande and Chatterjee, 2009).  Obesity-related medical costs in general are
expected to rise significantly because today’s obese children are likely to become tomorrow’s 
obese adults.
Current approaches to weight management include lifestyle modification, pharmacotherapy, 
and invasive bariatric procedures.  Lifestyle modification involves a combination of diet, 
exercise, and behavioral change, and is the preferred and essential strategy for weight 
management in obese and overweight individuals.  Although lifestyle modification can be 
very efficacious in some patients, adherence to the prescribed regimens is often poor.  As 
such, lifestyle modification alone is often not adequate and the weight loss is often transient.  
On the other hand, bariatric surgery and various other invasive procedures are generally 
reserved for the severely obese population. 
Pharmacotherapy can play a significant role in weight management programs, and is often 
combined with lifestyle modification to enhance weight loss beyond that which is normally 
achieved with diet and exercise alone.  Current pharmacotherapies offer the potential to 
significantly augment weight loss when combined with diet and exercise.

The current standard of care for treatment of obesity in pediatric subjects ranges from 
lifestyle intervention in children less than 8 years of age to use of pharmacotherapy in 
adolescents over 12 years of age (McGovern, et al, 2008; Spear, et al, 2007).  Xenical®
(orlistat) is currently the only product available for weight control in obese adolescent 
patients 12 to 16 years of age.  However, it is associated with gastrointestinal side effects 
(Xenical PI. 2015), and the treatment effect of Xenical is modest. In a study that included 
539 obese adolescents with BMI above the 97th percentile, Xenical demonstrated a 0.86 BMI 
reduction relative to placebo after 52 weeks of treatment (-0.55 BMI in the Xenical treatment 
group versus +0.31 BMI in the placebo group) (FDA, 2003; Chanoine, et al, 2005).
Obtaining maximum retention in the study is a major goal in order to minimize missing data.  
A number of strategies have been used in prior adolescent weight loss studies that will be 
used in the present study to help retain participants.  These include a highly trained and 
competent staff, ample waiting area, readily available parking (at no cost), access to mass 
transit, and reminder and follow-up calls.  In addition, we will provide fun and interactive 
group sessions with games and hands-on nutrition and physical activity demonstrations, 
random raffle drawings, social events, birthday and holiday cards, and newsletters.  Families 
will receive a reimbursement of $30 per family for assessments completed at Baseline and 
Month 6, and $100 at Month 12.
Further, we will make home visits for assessments for 
families, as needed, to maximize data collection. We anticipate achieving a 75% or greater 
retention rate at Month 12.
By using these retention strategies, we hope that we will 
maximize participant retention, which will help us cope with missing data.
7.1.1
APD356/Belviq (lorcaserin hydrochloride)
7.1.1.1
Mechanism of Action
Belviq is a selective serotonin 2c receptor agonist which was approved by the US Food and 
Drug Administration (FDA) on 27 Jun 2012 as an adjunct to a reduced-calorie diet and 
increased physical activity for chronic weight management in adult patients with a BMI of at 
least 30 kg/m2 (obese), or adult patients with a BMI greater than or equal to 27 kg/m2
(overweight) in the presence of at least 1 weight-related comorbid condition.
7.1.1.2
Clinical Experience with APD356/Belviq (lorcaserin hydrochloride)
The Phase 3 clinical evaluation of Belviq in studies of more than 7700 adult subjects, 
including 604 subjects with Type 2 diabetes mellitus, demonstrated clinically meaningful 
efficacy and a safety profile that includes minimal and easily managed risks.  In each of the 
individual studies and in the pooled efficacy analyses, the Belviq dose met the following 
prespecified endpoints:


A significantly greater proportion of adult subjects taking Belviq 10 mg twice per day 
(BID) (47%) lost at least 5% of baseline body weight at 52 weeks as compared to 
subjects taking placebo (23%).  A significantly greater proportion of subjects taking 
Belviq 10 mg BID (22.4%) lost at least 10% of baseline body weight at 1 year as 
compared to subjects taking placebo (8.7%). 

The mean weight loss at 1 year in adult subjects taking Belviq 10 mg BID (-5.8 kg) 
was significantly greater than that in subjects taking placebo (-2.5 kg).
An integrated evaluation of the data from the pediatric, adolescent, and adult subjects 
revealed that the relationship between lorcaserin area under the curve (AUC) and body 
weight in pediatric and adult subjects is consistent irrespective of the individual studies or 
age range of the study population. Irrespective of age, lorcaserin AUC values in the pediatric 
subjects with body weight of greater than 60 kg overlapped with the data observed from the 
studies involving adult subjects, suggesting a fixed dose approach similar to adults can be 
used for children and adolescent subjects with body weight greater than 60 kg.
In preadolescent and adolescent obese populations, it is anticipated that Belviq XR will result 
in similar effects.
As part of FDA postmarketing requirements, this study is designed to 
characterize the efficacy and safety of Belviq XR in adolescent obese populations in the 
United States, as well as in children ages 9 to 11 years.  It is also intended to support an 
indication for chronic weight management for obese children and adolescents ages 9 to 
17 years. Thirty percent of the subjects 9 to 11 years of age from this study will be stratified 
and added to the 50 subjects 6 to 8 years of age in the open label pharmacokinetic (PK) only 
cohort in the APD356-404 study to be used to support a safety population (n=110) in the 
open label study designed for obese subjects 6 to 8 years of age using partial extrapolation 
with PK for efficacy.
7.2
Study Rationale
There is no specific FDA guidance for the approval of a weight loss product for children and 
adolescents.  In adults, the Division’s 2007 draft Guidance for Industry Developing Products 
for Weight Management indicate that the product needs to satisfy either of the following
mean or categorical criteria after 1 year of treatment:

The difference in mean weight loss between the active-product and placebo-treated 
groups is at least 5% and the difference is statistically significant.

The proportion of subjects who lose at least 5% of baseline body weight in the 
active-product group is at least 35%, is approximately double the proportion of 
subjects in the placebo-treated group who lose at least 5% of baseline body weight, 
and the difference between groups is statistically significant.
FDA awarded a weight management indication for Belviq based on Phase 3 study results 
which achieved the categorical criteria. In a Phase 3 study, a significantly greater proportion 
of subjects taking Belviq (47%) lost at least 5% of baseline body weight at 1 year as 
compared to subjects taking a placebo (23%).  It is anticipated that a similar effect will be 
demonstrated in older children (9 to 11 years of age) and obese adolescents, where weight

loss will be assessed using BMI measurements to account for growth. In this study, the 
objective is to demonstrate that BMI reduction will be achieved during 52 weeks of treatment 
with Belviq XR 20 mg administered once daily (QD) compared to placebo in obese children 
and adolescents.
In the Phase 3 orlistat study in obese adolescents and children mentioned above, the 
proportion of subjects who lost at least 5% body weight is relatively low. At the end of the 
study at Week 52, only 26.5% of the subjects achieved a 5% or greater BMI reduction 
compared to 15.7% in the placebo group. The placebo-corrected BMI reduction was about 
0.86 kg/m2.  
There are limited trials for weight reduction in the adolescent population, ages 12 to 17 years,
and none in children under the age of 9 years (Peirson, et al, 2015).  Thirty-one studies 
(29 behavioral, 2 pharmacological and behavioral) were included in a meta-analysis of 
randomized studies conducted in primary care centers in overweight and obese children and 
youth ages 2 to 18 years using behavioral (diet, exercise, and lifestyle) and pharmacological 
interventions and providing 6-month postbaseline BMI or prevalence of overweight or 
obesity. 
Both interventions showed a significant effect on BMI in favor of treatment 
(behavioral: 
standardized mean difference [SMD] -0.54, 95% confidence interval 
[CI] -0.73, -0.36; orlistat plus behavioral: SMD -0.43, 95% CI -0.60, -0.25). The studies 
reported no significant difference between groups in the likelihood of reduced prevalence of 
overweight or overweight and obese. A great deal of variation was noted across efficacious 
interventions.
In conclusion, this meta-analysis demonstrated low-quality evidence that 
behavioral treatments alone are associated with a smaller effect in terms of reduced BMI 
compared with the effect shown by combined behavioral and pharmacological interventions. 
This may be because the effect size in the randomized, double blind, placebo controlled,
phase 3 orlistat study in adolescents was relatively low and there was a lack of maintenance 
effect. These subjects started to regain their BMI after 6 months of treatment. At end of the 
study, only 26.5% of subjects achieved a 5% or greater BMI reduction compared to 15.7% in 
placebo group. In a sibutramine Phase 3 study in obese adolescents, a substantially higher 
proportion of subjects (69%) treated with sibutramine achieved at least a 5% BMI reduction 
compared to 21% of subjects in the placebo group. In addition, sibutramine resulted in a
substantial reduction in mean BMI (between-group difference, 2.9 kg/m2) and mean weight 
(between-group difference, 8.4 kg) compared to placebo (Berkowitz, et al, 2006).  Unlike the 
weight loss effect of Belviq in adults and sibutramine in adolescents, subjects in the orlistat 
study started to increase their BMI after 6 months of treatment.
In this proposed study, it is assumed that treatment with Belviq XR 20 mg will lead to a BMI
reduction of more than 1 kg/m2, and a higher proportion of subjects will achieve more than a 
5% and 10% BMI reduction compared to placebo.  A between-group difference of 24% is the 
basis for the conservative assumption of a 20% effect size in the current study.
In addition, the total sample size of 360 subjects will be adequate to assess safety and 
exposure based on previous adolescent studies with weight management products (orlistat 
and sibutramine) (FDA, 2003; Chanoine, et al, 2005; Berkowitz, et al, 2006) and other 
metabolic or dyslipidemia medication products (ezetimibe, simvastatin) (FDA, 2007).

INVESTIGATIONAL PLAN
9.1
Overall Study Design and Plan
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in 
obese children and adolescents ages 9 to 17 years.  Approximately 360 subjects will be 
randomized in a 1:1 ratio to Belviq XR 20 mg QD (180 subjects) and placebo (180 subjects).  
Subjects will be stratified by age group and sex.  At least 30% of total subjects should be 
ages 9 to 11 years for the reasons outlined above in Section 7.1.1.2.  Subjects will receive 
Belviq XR 20 mg or placebo QD in a 1:1 ratio for up to 52 weeks. Throughout the duration 
of the study, subjects will be encouraged to adhere to a lifestyle modification program that 
includes diet and exercise counseling (see Appendix 2).  
The study will consist of 2 phases:
Prerandomization and Randomization.  The 
Prerandomization Phase will last up to 30 days and consists of 1 visit during which subjects 
will be screened for eligibility.  The Randomization Phase consists of a Treatment Period and 
a Follow-Up Period.  The Treatment Period will last for a maximum of 52 weeks, with visits 
at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52; the Follow-Up Period will extend from the 
End of Treatment (EOT) visit to the End of Study (EOS) visit.
Subjects who screen fail can be re-screened only once after 60 days.  All subjects will 
continue in the study until the 52-week evaluation is completed.  Subjects who discontinue 
treatment prematurely will be followed up until study completion.

9.1.1.1
Screening Period
The purpose of the Screening Period is to obtain the informed consent and assent and to 
establish protocol eligibility.  Procedures to be followed when obtaining informed consent 
are detailed in Section 5.3.  Careful initial screening is important in the recruitment of 
families who both fully understand the requirements of this 1 year, randomized, controlled 
trial and are truly interested in participation.  Interested caregivers and adolescents will be 
screened by phone to assess preliminary entry criteria.  Candidates will be given a brief 
description of the program and general study requirements, with an adolescent and a 
caregiver who is willing to participate.  If preliminary entry criteria are met, adolescents and 
their caregivers will be invited to an initial in-clinic meeting to further discuss the study.  A 
complete description of the study including assessments, the number of visits, the lifestyle 
program, the fact that the adolescent would be taking either the study drug or a placebo, the
duration of the study, and the necessity of having an adolescent wishing to participate as well 
as a participating caregiver will be described.  Consent and assent will be obtained and copies 
of the signed forms will be provided to families.  The importance of the study and its 
scientific merit will be discussed.  Ineligible adolescents will be referred to local weight 
management resources.  Screening period assessments and timing thereof are shown in 
Section 9.5.2.

Discussion of Study Design, Including Choice of Control Groups
The proposed dose and dosing frequency of Belviq XR in this study is 20 mg QD.  The PK 
parameters of a single 10-mg dose of Belviq were evaluated in healthy, adolescent obese 
subjects in Study APD356-025 and healthy, obese pediatric subjects ages 6 to 11 years in 
Study APD356-A001-026.  Overall, the PK parameters of Belviq and its main metabolites, 
M1 and M5, were similar to those in adults.  Following a single, oral administration of 
Belviq 10 mg to a total of 8 healthy adolescent (age 12 to 17 years) obese subjects, the mean 
maximum concentration observed and the area under the concentration-time curve from time 
zero to infinity (AUC(0-inf)) were 36.5 ng/mL and 464 hr×ng/mL, respectively.  The mean 
Belviq terminal phase half-life was 9.70 hours, similar to that observed in adults, thus 
supporting a similar dosing frequency (QD) in adolescent subjects.
Additionally, a single dose PK study in 8 healthy obese pediatric subjects ages 6 to 11 years 
of age was recently completed.
The PK analysis after a single 10-mg dose of lorcaserin 
revealed that the lorcaserin AUC(0-inf) values tended to increase with decreasing body weight 
and age. However, the body weight normalized AUC(0-inf) values were similar across the age 
groups, therefore the data indicated no effect of age on the lorcaserin PK.
Integrated 
assessment of the PK versus body weight relationship, pooling the data from pediatric and 
adult subjects from previous studies, suggested that the lorcaserin area under the curve values 
for subjects with body weight of at least 60 kg overlapped with the area under the curve
values from adolescents and adults. Therefore, no dose adjustment relative to adults and 
adolescents is deemed necessary for pediatric subjects with a body weight of at least 60 kg.
Based on CDC growth charts, the likelihood of enrolling subjects who are younger than 
9 years of age with body weight of at least 60 kg is low; therefore, the current study is 
designed to enroll the subjects between 9 to 17 years of age.
The targeted study population comprises 360 obese children and adolescents 9 to 17 years of
age.
Obese adolescents will be identified using gender- and age-specific BMI measurement.  
Obesity in adolescents is defined by US Expert committee recommendations as BMI in or 
above the 95th percentile (Barlow, 2007).
Obesity in children will be identified using 
gender- and age-specific BMI measurement.  Obesity in children (9 to 11 years of age) is 
defined by The American Academy of Pediatrics 2007 recommendation as BMI in the 
99th percentile and at least 1 co-morbidity (Spear, et al, 2007).

The proposed patient population is consistent with the recommendations in the 
2007 American Academy of Pediatrics article, Recommendations for Treatment of Child and 
Adolescent Overweight and Obesity (Spear, et al, 2007), which supports medication use in 
the 6 to 11 year age group as part of a staged approach (Tertiary Care Intervention in patients 
with a BMI 99th percentile and at least 1 co-morbidity).  Although we acknowledge that 
recommendations are not necessarily different for the older children and adolescents in this 
publication, utilizing broader inclusion criteria in the 12 to 17 year age group allows for more 
generalizability, whereas the more stringent approach in the 6 to 11 year age group better 
balances potential benefits with some of the uncertainties of treatment in this age group.
Randomization will be used in this study to avoid bias in the assignment of subjects to 
treatment, to increase the likelihood that known and unknown subject attributes (eg, 
demographics, baseline characteristics) are balanced across treatment groups, and to ensure 
the validity of statistical comparisons across treatment groups.  Blinding to treatment will be 
used to reduce potential bias during data collection and evaluation of endpoints.

Selection of Study Population
Approximately 700 subjects will be screened to ensure that 360 subjects will be randomized.

Storage Conditions
Where applicable, investigational product will be stored in accordance with the DEA 
Regulations for Scheduled III to V Drugs and labeled storage conditions.  Temperature 
monitoring is required at the storage location to ensure that the study drug is maintained 
within an established temperature range.  The investigator or designee is responsible for 
ensuring that the temperature is monitored throughout the total duration of the study and that 
records are maintained; the temperature should be monitored continuously by using either an 
in-house validated data acquisition system, a mechanical recording device, such as a 
calibrated chart recorder, or by manual means, such that minimum and maximum 
thermometric values over a specific time period can be recorded and retrieved as required.
9.4.3
Method of Assigning Subjects to Treatment Groups
Subjects will be assigned to treatments based on a computer-generated randomization 
scheme that will be reviewed and approved by an independent statistician.  The 
randomization scheme and identification for each subject will be included in the final clinical 
study report for this study.
Subjects will be centrally stratified by age group (9 to 11 years old and 12 to 17 years old)
and sex (male and female).  Within each stratum, subjects will be randomized to receive 
either Belviq XR 20 mg or placebo QD in a 1:1 ratio.  It is planned that at least 30% of the 
subjects will be enrolled into the 9 to 11 year age group.  
Randomization will be performed centrally by an interactive voice or web response system 
(IxRS).  The IxRS or clinical supply vendor will generate the randomized identification
numbers to be included on study packaging.  Upon signature of the ICF, the investigator or 
designee will access the IxRS to register the subject information.  At Randomization, the 
IxRS will assign each subject a unique randomization number.  At each subsequent visit 
during the Treatment Period and Follow-Up Period, the investigator or designee will access 
IxRS to obtain dispensing information and to register the subject’s visit.
9.4.4
Selection and Timing of Dose for Each Subject
Subjects should take the study medication once daily, and be encouraged to take the study 
medication with an adequate amount of water (8 oz. or 240 mL).
9.4.5
Blinding
During the Randomization Phase, subjects and all personnel involved with the conduct and 
interpretation of the study, including investigators, site personnel, and sponsor staff will be 
blinded to the treatment codes.  Randomization data will be kept strictly confidential, filed 
securely by an appropriate group with the sponsor or CRO, and accessible only to authorized 
persons (eg, Eisai Global Safety) until the time of unblinding, per the SOP.

A master list of all treatments and the subject numbers associated with them will be 
maintained in a sealed envelope by the clinical supply vendor, the IxRS vendor, and the 
sponsor.  In the event that emergency conditions require knowledge of the study treatment 
given, the blind may be broken via the code breaker facility within the IxRS.  Emergency 
procedures for revealing drug codes are given in Section 9.5.4.5.  If possible, before breaking 
the blind, the investigator should consult with the sponsor or designee to ascertain the 
necessity of breaking the code.
9.4.6
Prior and Concomitant Therapy
Any medication (including OTC medications) or therapy administered to the subject during 
the study (starting at the date of informed consent) will be recorded on the Prior and
Concomitant Medication Case Report Form (CRF) or Non-Pharmacological Procedures 
CRF.  The investigator will record on the Adverse Event CRF any AE for which the 
concomitant medication/therapy was administered. If the concomitant medication/therapy is 
being administered for a medical condition present at the time of entry into the study, the 
investigator will record the medical condition on the Medical History and Current Medical 
Condition CRF.
Other products intended for weight loss including prescription drugs, OTC drugs, and herbal 
preparations are prohibited as concomitant medications.  OTC cold medicines containing 
dextromethorphan can be used for up to 7 days and study medication is temporarily stopped 
for that time period and resumed the next day after the OTC cold medicine is stopped.  Any

9.5.1.5.1
ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered an investigational product.  An AE does not necessarily have a causal 
relationship with the medicinal product.  For this study, the study drug is Belviq XR
(lorcaserin hydrochloride).
The criteria for identifying AEs in this study are:
•
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or 
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE)
•
Any new disease or exacerbation of an existing disease 
•
Any deterioration in non-protocol-required measurements of a laboratory value or other 
clinical test (eg, ECG, x-ray) that results in symptoms, a change in treatment, or 
discontinuation of study drug
•
Recurrence of an intermittent medical condition (eg, headache) not present pretreatment 
(Baseline)
•
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of study drug, or withholding 
of study drug, whether prescribed in the protocol or not.
All AEs observed during the study will be reported on the Adverse Event CRF.  All AEs, 
regardless of relationship to study drug or procedure, should be collected beginning from the 
time the subject signs the study ICF through the last visit in the Treatment Phase.  Subjects 
who fail screening primarily due to AE(s) must have the AE(s) leading to screen failure 
reported on the Screening Disposition CRF.  SAEs will be collected for 28 days after the last 
dose.
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute 
an AE.  Medical and scientific judgment should be exercised in deciding whether an isolated 
laboratory abnormality should be classified as an AE.  Any laboratory abnormality 
considered to constitute an AE should be reported on the Adverse Event CRF. 
Abnormal ECG (corrected QT interval [QTc]) results, if not otherwise considered part of a 
clinical symptom that is being reported as an AE, should be considered an AE if the QTc 
interval is greater than 450 msec and there is an increase of more than 60 msec from baseline.  
Any ECG abnormality that the investigator considers as an AE should be reported as such.

It is the responsibility of the investigator to review the results of the C-SSRS, CDI-2, and 
WRAML-2 in all subjects and determine if any result constitutes an AE.  Medical and 
scientific judgment should be exercised in deciding whether an isolated suicidality rating 
scale response should be classified as an AE (see Section 9.5.1.5.8 for a description of the 
C-SSRS).
All AEs must be followed for 28 days after the subject’s last dose or until resolution, 
whichever comes first.  All SAEs must be followed to resolution or, if resolution is unlikely, 
to stabilization.
Every effort must be made by the investigator to categorize each AE according to its 
severity and its relationship to the study treatment.
Assessing Severity of Adverse Events
Adverse events will be graded on a 3-point scale (mild, moderate, severe) and reported in the 
detail indicated on the CRF.  The definitions are as follows:
Mild
Discomfort noticed, but no disruption of normal daily activity
Moderate Discomfort sufficient to reduce or affect normal daily activity
Severe
Incapacitating, with inability to work or to perform normal daily activity
The criteria for assessing severity are different than those used for seriousness (see
Section 9.5.1.5.2 for the definition of an SAE).
Assessing Relationship to Study Treatment
Items to be considered when assessing the relationship of an AE to the study treatment are:
•
Temporal relationship of the onset of the event to the initiation of the study treatment
•
The course of the event, especially the effect of discontinuation of study treatment or 
reintroduction of study treatment, as applicable
•
Whether the event is known to be associated with the study treatment or with other 
similar treatments
•
The presence of risk factors in the study subject known to increase the occurrence of 
the event
•
The presence of nonstudy, treatment-related factors that are known to be associated 
with the occurrence of the event
Classification of Causality
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question:
Page 783 of 897

Clinical Study Protocol
APD356-A001-403
Eisai
FINAL:  22 Jul 2016
Confidential
Page 45 of 83
Is there a reasonable possibility that the study drug caused the AE?
Yes (related)
A causal relationship between the study drug and the AE is a reasonable 
possibility.
No (not related) A causal relationship between the study drug and the AE is not a 
reasonable possibility.
9.5.1.5.2
SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An SAE is any untoward medical occurrence that at any dose:
•
Results in death
•
Is life-threatening (ie, the subject was at immediate risk of death from the AE as it 
occurred; this does not include an event that, had it occurred in a more severe form or 
was allowed to continue, might have caused death)
•
Requires inpatient hospitalization or prolongation of existing hospitalization
•
Results in persistent or significant disability/incapacity
•
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug)
Other important medical events that may not be immediately life-threatening or result in 
death or hospitalization but, when based on appropriate medical judgment, may jeopardize 
the subject or may require intervention to prevent one of the outcomes in the definition of 
SAE listed above should also be considered SAEs.  Medical and scientific judgment should 
be exercised in deciding whether expedited reporting is appropriate in such situations. 
For this study, the following events should always be considered serious and reported as an 
important medical event if it does not meet other serious criteria:
•
Serotonin syndrome (must have at least 1 of the following: Spontaneous clonus; 
Inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus)
•
Psychosis
•
Suicidal behavior
•
Priapism
•
New onset valvular heart disease
•
New onset PH
•
Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas 
of the skin
•
Fibroadenomas of the breast or ductal carcinoma in situ

In addition to the above, events associated with special situations include pregnancy or 
exposure to study drug through breastfeeding; AEs associated with study drug overdose, 
misuse, abuse, or medication error.  These events associated with special situations are to be 
captured using the SAE procedures but are to be considered as SAEs only if they meet one of 
the above criteria.  All AEs associated with special situations are to be reported on the CRF 
whether or not they meet the criteria for SAEs.  
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization.
The following hospitalizations are not considered to be SAEs because there is no “AE” (ie, 
there is no untoward medical occurrence) associated with the hospitalization:
•
Hospitalizations for respite care
•
Planned hospitalizations required by the protocol  
•
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed after study drug administration)
•
Hospitalization for administration of study drug or insertion of access for 
administration of study drug
•
Hospitalization for routine maintenance of a device (eg, battery replacement) that was 
in place before study entry

OTHER SAFETY ASSESSMENTS
WRAML-2
The WRAML-2 administration will consist of the Core Battery, which provides scores on 
Verbal Memory, Visual Memory, and Attention/Concentration.  There are 6 subtests (2 for 
each area).
The tests provide standardized scores based on age and gender, and are 
appropriate for ages 5 to 90 years.  The WRAML-2 will be used to assess lorcaserin effects 
on cognitive function. In addition, signs and symptoms of cognitive related AEs, including 
impairments in attention, memory, and adverse effects on schoolwork will be captured in the 
eCRF.
CDI-2
The CDI-2 is a self-administered depression rating scale for use in children ages 7 to 
17 years.  It consists of 28 items and provides a total score, scores on 2 scales, and 
4 subscales.  CDI-2 will be used to assess lorcaserin effect on mood changes.
C-SSRS
The C-SSRS collects information pertinent to suicidal ideation and actions.  It consists of a 
Baseline version which will be administered at baseline and a Since Last Visit version which 
will be administered at the remaining visits.  C-SSRS will be used to assess signal of 
depression and suicidal ideation or behavior. It will be performed at Baseline and at study 
visits as designated in the Schedule of Procedures/Assessments (Table 2).
Signs and symptoms of priapism (painful erection) and hyperprolactinemia (menstrual cycle 
abnormalities or galactorrhea) will be captured in the eCRF.
Hand X-Ray will be evaluated for any potential negative effect on bone age as designated in 
the Schedules/Assessments (Table 2). Echocardiograms will be performed on the subjects 
with signs or symptoms of potential valvular disease or PH. Echocardiogram confirmed 
cases of FDA-defined valvulopathy or PH will be captured by AE eCRF. Neuromuscular 
sign assessment for serotonin syndrome will be performed as designated in the Schedule of 
Procedures/Assessments (Table 2) to screen for potential serotonergic syndrome components. 
Serotonergic syndromes that meet the diagnostic criteria will be captured by AE eCRF.

Reporting of Serious Adverse Events, Pregnancy, and Events Associated 
with Special Situations
9.5.4.1
Reporting of Serious Adverse Events
All SAEs, regardless of their relationship to study treatment, must be reported on a 
completed SAE form by email or fax as soon as possible but no later than 1 business 
day from the date the investigator becomes aware of the event.
SAEs, regardless of causality assessment, must be collected through the through the last visit
and for 28 days after the subject’s last dose.  All SAEs must be followed to resolution or, if 
resolution is unlikely, to stabilization.  Any SAE judged by the investigator to be related to 
the study treatment or any protocol-required procedure should be reported to the sponsor 
regardless of the length of time that has passed since study completion.
The detailed contact information for reporting of SAEs is provided in the Investigator Study 
File.
For urgent safety issues, please ensure all appropriate medical care is administered to the 
subject and contact the appropriate study team member listed in the Investigator Study File.
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report.  This includes the investigator’s assessment of causality.
Any follow-up information received on SAEs should be forwarded within 1 business day of 
its receipt.  If the follow-up information changes the investigator’s assessment of causality, 
this should also be noted on the follow-up SAE form.
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested by 
the sponsor.
The investigator must notify his/her IRB/IEC of the occurrence of the SAE, in writing, if 
required by their institution.  A copy of this communication must be forwarded to the sponsor 
to be filed in the sponsor’s Trial Master File.
9.5.4.2
Reporting of Pregnancy and Exposure to Study Drug through Breastfeeding
Any pregnancy in which the estimated date of conception is either before the last visit or 
within 30 days of last study treatment or any exposure to study drug through breastfeeding 
during study treatment or within 30 days of last study treatment must be reported.
If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, this 
should be reported regardless of the length of time that has passed since the exposure to study 
treatment.

Page 56 of 83
A congenital anomaly, death during perinatal period, an induced abortion, or a spontaneous 
abortion are considered to be an SAE and should be reported in the same time frame and in 
the same format as all other SAEs (see Section 9.5.4.1).
Pregnancies or exposure to study drug through breastfeeding must be reported by fax or 
email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy.  The contact information for the reporting of pregnancies 
and exposure to study drug through breastfeeding is provided in the Investigator Study File.  
The Pregnancy Report Form must be used for reporting.  All pregnancies must be followed to 
outcome.  The outcome of the pregnancy must be reported as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the outcome.
A subject who becomes pregnant must be withdrawn from the study. 
9.5.4.3
Reporting of Events Association with Special Situations
9.5.4.3.1
REPORTING OF ADVERSE EVENTS ASSOCIATED WITH STUDY DRUG OVERDOSE,
MISUSE, ABUSE, OR MEDICATION ERROR
Adverse events associated with study drug overdose, misuse, abuse, and medication error 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication error are defined as follows:
Overdose
Accidental or intentional use of the study drug in an amount higher
than the protocol-defined dose
Misuse
Intentional and inappropriate use of study drug not in accordance with 
the protocol or authorized dose, route of administration, or 
indication(s) or use of prescription-only study drug without a 
prescription
Abuse
Sporadic or persistent intentional excessive use of study drug 
accompanied by harmful physical or psychological effects
Medication error
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of the 
healthcare professional, subject, or consumer.  Such events may be 
related to professional practice, healthcare products, occupational 
exposure, procedures, or
systems,
including prescribing,
order 
communication,
product
labeling, 
packaging, 
nomenclature,
compounding,
dispensing,
distribution,
administration, education,
monitoring, or use.
All AEs associated with overdose, misuse, abuse, or medication error should be captured on 
the Adverse Event CRF and also reported using the procedures detailed in Section 9.5.4.1
even if the AEs do not meet serious criteria.  Abuse is always to be captured as an AE.  If the 
Page 795 of 897

Page 57 of 83
AE associated with an overdose, misuse, abuse, or medication error does not meet serious 
criteria, it must still be reported using the SAE form and in an expedited manner but should 
be noted as nonserious on the SAE form and the Adverse Event CRF.
9.5.4.3.2
REPORTING OF STUDY-SPECIFIC EVENTS
Study-specific events (listed below) should always be considered as serious important 
medical events and be entered on the Adverse Event CRF and reported using the procedures 
detailed in Reporting of Serious Adverse Events (Section 9.5.4.1), even if the study-specific 
event does not meet other serious criteria.  

Serotonin syndrome
Must have at least 1 of the following: spontaneous clonus; 
inducible clonus plus agitation or diaphoresis; Ocular clonus plus agitation or 
diaphoresis; Tremor plus hyperreflexia; Hypertonia plus temperature above 38ºC plus
ocular clonus or inducible clonus

Psychosis

Suicidal behavior 

Priapism

New onset of valvular heart disease

New onset PH

Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas 
of the skin

Fibroadenomas of the breast or ductal carcinoma in situ

The following additional study specific AE of interest should be reported using the 
procedures detailed in Reporting of SAEs (Section 9.5.4.1), even if the study-specific 
event does not meet serious criteria.  If the event meets seriousness criteria, it should 
be reported as an SAE as above.  However, if the event listed below does not meet 
serious criteria, it should be noted as nonserious on the Adverse Event CRF:  Suicidal 
ideation

Euphoria 
9.5.4.4
Expedited Reporting
The sponsor must inform investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (ie, within 
specific time frames).  For this reason, it is imperative that sites provide complete SAE 
information in the manner described above.
9.5.4.5
Breaking the Blind
In the case of a medical emergency where the appropriate treatment of the subject requires 
knowledge of the study treatment given, the investigator may break the randomization code 
Page 796 of 897

Clinical Study Protocol
APD356-A001-403
Eisai
FINAL:  22 Jul 2016

Page 58 of 83
for an individual subject.  In all such cases, the AE necessitating the emergency blind break 
will be handled as an SAE in accordance with the procedures indicated above.  Any broken 
code will be clearly justified and documented.  The medical monitor must be notified 
immediately of the blind break.
9.5.4.6
Regulatory Reporting of Adverse Events
Adverse events will be reported by the sponsor or a third party acting on behalf of the 
sponsor to regulatory authorities in compliance with local and regional law and established 
guidance.  The format of these reports will be dictated by the local and regional 
requirements.
9.5.5
Completion/Discontinuation of Subjects
The investigator may withdraw the subject from the study at any time for safety or 
administrative reasons.  A subject may elect to discontinue the study at any time for any 
reason.  All subjects will continue in the study until the 52 week evaluation is completed.  
Subjects who discontinue treatment prematurely will be followed up until study completion.  
All subjects who discontinue the study are to complete the study’s early discontinuation 
procedures indicated in the Schedule of Procedures/Assessments (Table 2).
The investigator will promptly explain to the subject involved that the study will be 
discontinued for that subject and provide appropriate medical treatment and other necessary 
measures for the subject.  A subject who has ceased to return for visits will be followed up by 
mail, phone, or other means to gather information such as the reason for failure to return, the 
status of treatment compliance, the presence or absence of AEs, and clinical courses of signs 
and symptoms.
Subjects who discontinue early from the study will be discontinued for 1 of these primary 
reasons: AE(s), lost to follow-up, subject choice, withdrawal of consent, pregnancy, study 
terminated by sponsor, or other.  In addition to the primary reason, the subject may indicate
1 or more of secondary reasons for discontinuation.  Study disposition information will be 
collected on the Subject Disposition CRF.
Detailed retention strategies will be developed and included in study manual. These include 
a highly trained and competent staff, easy access to the clinic, reminder and follow-up calls, 
interactive group sessions with games and hands-on nutrition and physical activity 
demonstrations, random raffle drawings, social events, birthday and holiday cards, and
newsletters. In addition, home visits for assessments of families will be an option, as needed, 
to maximize data collection. This detailed retention plan will help prevent missing data.
A subject removed from the study for any reason may not be replaced.

9.5.6
Abuse or Diversion of Study Drug
During the study, the investigator will report any concern about abuse or diversion of study 
drugs by completing the Abuse or Diversion of Study Drug CRF.  The DEA Registrant has 
the responsibility to comply with local, state, and Federal laws to notify the Field Division 
Office of the DEA of any theft or significant loss of any controlled substances upon 
discovery of such theft or loss.
9.5.7
Confirmation of Medical Care by Another Physician
The investigator will instruct subjects to inform site personnel when they are planning to 
receive medical care by another physician.  At each visit, the investigator will ask the subject 
whether he or she has received medical care by another physician since the last visit or is 
planning to do so in the future.  When the subject is going to receive medical care by another 
physician, the investigator, with the consent of the subject, will inform the other physician 
that the subject is participating in the clinical study.
9.6
Data Quality Assurance
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines.  Site audits 
will be made periodically by the sponsor’s or the CRO’s qualified compliance auditing team, 
which is an independent function from the study team responsible for conduct of the study.
9.6.1
Data Collection
Data required by the protocol will be collected on the CRFs and entered into a validated data 
management system that is compliant with all regulatory requirements.  As defined by ICH 
guidelines, the CRF is a printed, optical, or electronic document designed to record all of the 
protocol-required information to be reported to the sponsor on each study subject.
Data collection on the CRF must follow the instructions described in the CRF Completion 
Guidelines.  The investigator has ultimate responsibility for the collection and reporting of all 
clinical data entered on the CRF.  The investigator or designee as identified on Form 
FDA 1572 must sign the completed CRF to attest to its accuracy, authenticity, and 
completeness.
Completed, original CRFs are the sole property of Eisai and should not be made available in 
any form to third parties without written permission from Eisai, except for authorized 
representatives of Eisai or appropriate regulatory authorities.
9.6.2
Clinical Data Management
All software applications used in the collection of data will be properly validated following 
standard computer system validation that is compliant with all regulatory requirements.  All 
data, both CRF and external data (eg, laboratory data), will be entered into a clinical system.

Prior and Concomitant Therapy
All investigator terms for medications recorded in the CRF will be coded to an 11-digit 
character code using the World Health Organization Drug Dictionary.  The number 
(percentage) of subjects who took prior and concomitant medications will be summarized for
the Safety Analysis Set by treatment group, Anatomical Therapeutic Chemical class, and 
World Health Organization Drug Dictionary preferred term (PT).  Prior medications will be 
defined as medications that stopped before the first dose of study drug.  Concomitant 
medications will be defined as medications that started on or after the date of the dosing of 
study drug and continued up to 30 days afterward.
9.7.1.6
Efficacy Analyses
The FAS will be used as the primary analysis set for all efficacy analyses, while the PP will 
be used as a supportive analysis.  Unless specified otherwise, a 2-sided α=0.05 significance 
level will be used for all efficacy analyses.
Primary Efficacy Analysis
The primary efficacy endpoint is the change in BMI from Baseline to Week 52.  The change 
from baseline in BMI will be analyzed using the mixed effect model repeated measurement 
analysis (MMRM) with factors of treatment, visits (Baseline, Week 1, 5, 8, 12, 20, 28, 36, 
44, and 52), age group (9 to 11 years old and 12 to 17 years old), sex (male and female), 
treatment-by-visit interaction as fixed effect, subjects as random effect, and the baseline BMI 
as a covariate.  The unstructured covariance matrix will be used in the analysis and the 
treatment comparison at Week 52 will be the event of interest.  In case of a convergence 
issue, the Toeplitz covariance structure will be used in the model.
Subgroup analyses and additional sensitivity analyses will be performed as appropriate 
including multiple imputation methods assuming the missing values are missing at random 
(MAR) and missing not at random (MNAR) to handle missing data.
The following analyses will be considered as sensitivity analyses:

PP analysis: The same primary efficacy analyses described above will be repeated 
based on the PP.

Multiple imputation (MI): the same primary efficacy analyses described above will 
be analyzed using MI for impute the missing data, assuming the missing values are 
MAR and MNAR.

Change from baseline in standardized BMI score (Z-score):
The same primary 
efficacy analyses described above will be repeated using Z-score.
Additional sensitivity analyses may also be explored and described in the SAP, if deemed 
appropriate.

Key Secondary Efficacy Analysis
The key secondary efficacy endpoint is the proportion of subjects achieving at least a 
5% BMI reduction at Week 52.  The secondary efficacy endpoint will be analyzed only if the 
test for the primary efficacy endpoint is statistically significant.
The proportion of subjects achieving at least a 5% BMI reduction at Week 52 will be 
analyzed using a logistic regression model with factors of treatment, age group (9 to 11 years 
old and 12 to 17 years old) and sex (male and female), and baseline BMI as a covariate using 
FAS.  Subjects with any missing assessment at Week 52 will be considered as treatment 
failures in this analysis.
Other Secondary Efficacy Analyses
In general, for all other secondary efficacy endpoints, the continuous variables will be 
analyzed using MMRM and categorical variables will be analyzed using the Cochran Mantel 
Haenszel test, Chi-square test, or logistic regression as appropriate.  Additional analysis may
be performed as needed using appropriate statistical methodologies as specified in SAP.
Subgroup analyses will be performed on the primary efficacy endpoint, including age group 
(9 to 11 years old and 12 to 17 years old), sex (male and female), race (white, black, Asian,
and other). Additional subgroups may be explored, if deemed necessary.
No adjustment for multiplicity is planned for other secondary endpoints, subgroup, and 
sensitivity analyses.

Pharmacokinetic, Pharmacodynamic, Pharmacogenomic, and Other Biomarker
Analyses
9.7.1.7.1
PHARMACOKINETIC ANALYSES
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling.  The effect of covariates, such as baseline characteristics
or demographics, on PK will be explored.  Derived exposure parameters such as the 
maximum observed concentration and the area under the concentration-time curve from time
0 to 24 hours at steady-state will be calculated from the final PK model using individual 
posterior estimates of the PK parameters and from dosing history.  The PK analysis set will 
be used for this analysis.
9.7.1.7.2
PHARMACODYNAMIC ANALYSES
Probability of achieving at least a 5% and at least a 10% body weight reduction change from 
Baseline will be assessed as the PD analysis.  The PD analysis set will be used for this 
analysis.
Other assessments (eg, BMI change, percentage of BMI change, proportion [%] of patients 
achieving ≥10% BMI reduction, and change in waist circumference from baseline) will also 
assessed as PD analysis.  The PK/PD analysis set will be used for this analysis.

PHARMACOKINETIC/PHARMACODYNAMIC ANALYSES
Population PK/PD modeling will be used to explore the relationship between lorcaserin 
plasma exposure and response, including but not limited to change in body weight from 
baseline and the probability of achieving at least a 5% and at least a 10% change in body
weight from baseline to Week 52.  Additionally, exposure-safety relationships for select 
safety parameters may be explored graphically, depending on the data at the end of study.  
Any emergent relationship may be modeled as appropriate.  Any parameters based on the 
study data may be considered for exploratory assessment for its relationship to PK.

PHARMACOGENOMIC AND PHARMACOGENETIC ANALYSES
Not applicable
9.7.1.8
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  Safety assessments 
including the incidence of AEs (including changes from baseline in physical examination), 
growth (CDC growth chart and bone age determined by x-ray of the hand), sexual maturation 
(Tanner Staging), out-of-normal-range laboratory safety test values, change from baseline in 
laboratory safety test values (including biomarkers), ECGs, and vital sign measurements will 
be summarized by treatment group using descriptive statistics or frequency count as 
appropriate.  In addition, suicidal ideation, cognitive function, behavior, and mood will be 
evaluated by the C-SSRS, WRAML-2, CDI-2, and C-SSRS, respectively, and will also be 
summarized by treatment group using descriptive statistics or frequency count as appropriate.  
All WRAML-2 raw scores from the Core Battery will be converted to age and gender 
standard scores for purposes of intra individual comparisons
No hypothesis testing will be performed for the safety assessment.
Study Day 1 for all safety analyses will be defined as the date of the 1st dose of study drug.
9.7.1.8.1
EXTENT OF EXPOSURE
Subjects will receive Belviq XR 20 mg or placebo QD for up to 52 weeks. The extent of 
exposure will be characterized by duration of exposure (in weeks) for each treatment group.
Duration of exposure will be defined as the number of weeks between the date the subject 
received the 1st dose of study drug and the date the subject received the last dose of study 
drug.  Duration of exposure will be summarized using descriptive statistics by treatment 
group.  In addition, the duration of exposure will be categorized and will be summarized 
using frequency count by treatment group.
9.7.1.8.2
ADVERSE EVENTS
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities

(MedDRA).  Adverse events will be coded to the MedDRA (Version 18.0 or higher) lower 
level term closest to the verbatim term.  The linked MedDRA PT and primary system organ 
class (SOC) are also captured in the database.
A treatment-emergent AE (TEAE) is defined as an AE that emerges during treatment (up to 
28 days after the last dose of study drug), having been absent at pretreatment (Baseline) or 
•
Reemerges during treatment (up to 28 days after the last dose of study drug), having been 
present at pretreatment (Baseline) but stopped before treatment, or 
•
Worsens in severity during treatment relative to the pretreatment state, when the AE is 
continuous.
Only those AEs that were treatment emergent will be included in summary tables.  All AEs, 
treatment emergent or otherwise, will be presented in subject data listings.
The TEAEs will be summarized by treatment group.  The following summaries will be 
reported for TEAES:

Incidence of TEAEs in descending order of frequency

Incidence of TEAEs by SOC and PT

Incidence of treatment-related TEAEs by SOC and PT

Incidence of TEAEs by SOC, PT and maximum severity (mild, moderate, or severe)

Incidence of treatment-related TEAEs by SOC, PT, and maximum severity (mild, 
moderate, or severe)

Incidence of TEAEs by SOC, PT, and relationship to study drug (Yes [related] or No 
[not related]) 
A subject will be counted only once within a SOC or PT, if the subject experienced more 
than 1 TEAE within a specified SOC and PT.
The following summaries will also be presented for the treatment-emergent SAEs.

Incidence of TEAEs leading to death

Incidence of treatment-emergent SAE by SOC and PT

Incidence of treatment-related treatment-emergent SAE by SOC and PT
In addition, subjects with TEAEs leading to discontinuation from study drug and AEs of 
special interest as described in Section 9.5.4.3.2 will be summarized by MedDRA SOC and 
PT for each treatment group.

LABORATORY VALUES
Laboratory results will be summarized using Système International units, as appropriate.  For 
all quantitative parameters listed in Section 9.5.1.5.3, the actual value and the change from 
baseline to each postbaseline visit and to the end of treatment (defined as the last 
on-treatment value) will be summarized by visit and treatment group using descriptive 
statistics.  Percentages will be based on the number of subjects with both nonmissing 
baseline and relevant postbaseline results.
Laboratory test results will be assigned a low/normal/high (LNH) classification according to 
whether the value was below (L), within (N), or above (H) the laboratory parameter’s 
reference range.  Within-treatment comparisons for each laboratory parameter will be based 
on 3-by-3 tables (shift tables) that compare the baseline LNH classification to the LNH 
classification at the End of Treatment and the Follow-Up visits.  Similar shift tables will also 
compare the baseline LNH classification to the LNH classification for the highest and lowest 
value during the treatment period.
Appendix 1
presents the criteria that will be used to identify subjects with 
treatment-emergent markedly abnormal laboratory values (TEMAV).  Except for phosphate, 
a TEMAV is defined as a postbaseline value with an increase from baseline to a grade of 2 or 
higher.  For phosphate, a TEMAV was defined as a postbaseline value with an increase from 
baseline to a grade of 3 or higher.  When displaying the incidence of TEMAVs, each subject 
may be counted once in the laboratory parameter high and in the laboratory parameter low 
categories, as applicable.
9.7.1.8.4
VITAL SIGNS
Descriptive statistics for vital signs parameters (eg, systolic and diastolic BP, pulse, 
respiratory rate, temperature, weight) and changes from baseline will be presented by visit
and treatment group.
9.7.1.8.5
ELECTROCARDIOGRAMS
For each ECG parameter (including PR interval, RR interval, QRS interval, QT interval, QTc
interval (Bazett formula), QTc interval (Fridericia formula), and heart rate), the actual value 
and change from baseline will be summarized by visit and treatment group using descriptive 
statistics. 
Shift tables will present changes from baseline in ECG interpretation (categorized as normal; 
abnormal, not clinically significant; and abnormal, clinically significant) to end of treatment. 
Maximum postbaseline QTc (Bazett) and QTc (Fridericia) will also be tabulated by treatment 
group as follows:

Number (percentage) of subjects in greater than 450 msec, greater than 480 msec, and 
greater than 500 msec during the treatment, and

OTHER SAFETY ANALYSES
Other safety assessments including children and adolescent growth evaluations using CDC 
growth chart and bone age using x-ray of the hand, sexual maturation as measured in Tanner 
Staging, neuromuscular sign assessment for serotonin syndrome, signs and symptoms of 
priapism and prolactinemia, study drug effect on cognitive function assessed by WRAML-2, 
assessment of suicidality using C-SSRS, and mood assessment using CDI-2 will be also be 
summarized by treatment group at each scheduled visit.
9.7.2
Determination of Sample Size
The proposed sample size is based on the comparison of the primary efficacy endpoint, 
change from Baseline in BMI at Week 52 between the Belviq XR 20-mg treatment group and 
placebo group.  Assuming a SD of 2.2 kg/m2 and a 40% dropout rate, a sample size of 
360 subjects in a 1:1 ratio (n=180 in the Belviq XR 20-mg treatment group; n=180 in the 
placebo group) will have at least 90% power to detect a treatment difference of 1 kg/m2 in 
BMI, using a 2-sided t-test with α=0.05.  Assuming the proportion of subjects achieving at 
least a 5% BMI reduction at Week 52 is 20% for the placebo group and a 40% dropout rate, 
this sample of 360 subjects (180 subjects for Belviq XR 20 mg and 180 subjects for placebo) 
will also have greater than 85% power to detect an absolute difference of 20% between the 
Belviq XR 20-mg group and placebo group, using a 2-sided Fisher’s Exact test with α=0.05.  
The assumption used in the sample size calculation is based on the 2 pivotal lorcaserin 
studies, APD356-009 and APD356-011 in obese and overweight non-diabetic adult subjects.
9.7.3
Interim Analysis
No interim analysis is planned for this study.
9.7.4
Other Statistical/Analytical Issues
Further statistical and analytical issues will be discussed in the SAP.  
9.7.5
Procedure for Revising the Statistical Analysis Plan
If the SAP needs to be revised after the study starts, the sponsor will determine how the 
revision impacts the study and how the revision should be implemented.  The details of the 
revision will be documented and described in the clinical study report.

11 PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE
PROCEDURES)
11.1
Changes to the Protocol
Any change to the protocol requires a written protocol amendment or administrative change 
that must be approved by the sponsor before implementation.  Amendments specifically 
affecting the safety of subjects, the scope of the investigation, or the scientific quality of the 
study require submission to health or regulatory authorities as well as additional approval by 
the applicable IRBs/IECs.  These requirements should in no way prevent any immediate 
action from being taken by the investigator, or by the sponsor, in the interest of preserving 
the safety of all subjects included in the study.  If the investigator determines that an 
immediate change to or deviation from the protocol is necessary for safety reasons to 
eliminate an immediate hazard to the subjects, the sponsor’s medical monitor and the 
IRB/IEC for the site must be notified immediately.  The sponsor must notify the health or 
regulatory authority as required per local regulations.
Protocol amendments that affect only administrative aspects of the study may not require 
submission to health or regulatory authority or the IRB/IEC, but the health or regulatory 
authority and IRB/IEC should be kept informed of such changes as required by local 
regulations.  In these cases, the sponsor may be required to send a letter to the IRB/IEC and 
the Competent Authorities detailing such changes.
11.2
Adherence to the Protocol
The investigator will conduct the study in strict accordance with the protocol (refer to ICH
E6, Section 4.5).
11.3
Monitoring Procedures
The sponsor’s/CRO’s CRA will maintain contact with the investigator and designated staff 
by telephone, letter, or email between study visits.  Monitoring visits to each site will be 
conducted by the assigned CRA as described in the monitoring plan.  The investigator will 
allow the CRA to inspect the clinical, laboratory, and pharmacy facilities to assure 
compliance with GCP and local regulatory requirements.  The CRFs and subject’s 
corresponding original medical records (source documents) are to be fully available for 
review by the sponsor’s representatives at regular intervals.  These reviews verify adherence 
to study protocol and data accuracy in accordance with local regulations.  All records at the 
site are subject to inspection by the local auditing agency and IRB/IEC review.

Correspondence regarding a study subject’s treatment between physicians or memoranda 
sent to the IRBs/IECs
•
CRF components (eg, questionnaires) that are completed directly by subjects and serve as 
their own source
11.4
Recording of Data
A CRF is required and must be completed for each subject by qualified and authorized 
personnel.  All data on the CRF must reflect the corresponding source document, except 
when a section of the CRF itself is used as source document.  Any correction to entries made 
on the CRF must be documented in a valid audit trail where the correction is dated, the 
individual making the correct is identified, the reason for the change is stated, and the 
original data are not obscured.  Only data required by the protocol for the purposes of the 
study should be collected.
The investigator must sign each CRF.  The investigator will report the CRFs to the sponsor 
and retain a copy of the CRFs.
11.5
Identification of Source Data
All data to be recorded on the CRF must reflect the corresponding source documents.

11.6
Retention of Records
The circumstances of completion or termination of the study notwithstanding, the 
investigator is responsible for retaining all study documents, including but not limited to the 
protocol, copies of CRFs, the Investigator's Brochure, and regulatory agency registration 
documents (eg, Form FDA 1572 ICFs, and IRB/IEC correspondence).  In addition, the 
sponsor will send a list of treatment codes by study subject to the investigator after the 
clinical database for this study has been locked.  The site should plan to retain study 
documents, as directed by the sponsor, for at least 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region or at least 3 years have elapsed since the formal 
discontinuation of clinical development of the investigational product.
It is requested that at the completion of the required retention period, or should the 
investigator retire or relocate, the investigator contact the sponsor, allowing the sponsor the 
option of permanently retaining the study records.
11.7
Auditing Procedures and Inspection
In addition to the routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of ICH GCP and all applicable local 
regulations.  If a government regulatory authority requests an inspection during the study or 
after its completion, the investigator must inform the sponsor immediately.
11.8
Handling of Study Drug
All study drugs will be supplied to the PI (or a designated pharmacist) by the sponsor.  Drug 
supplies must be kept in an appropriate secure area (eg, locked cabinet) and stored according 
to the conditions specified on the drug labels.  Investigational product will be stored in 
accordance with the DEA Regulations for Scheduled III - V Drugs and labeled storage 
conditions.  The investigator (or a designated pharmacist) must maintain an accurate record 
of the shipment and dispensing of the study drug in a drug accountability ledger, a copy of 
which must be given to the sponsor at the end of the study.  An accurate record of the date 
and amount of study drug dispensed to each subject must be available for inspection at any 
time.  The CRA will visit the site and review these documents along with all other study 
conduct documents at appropriate intervals once study drug has been received by the site.
All drug supplies are to be used only for this study and not for any other purpose.  The 
investigator (or site personnel) must not destroy any drug labels or any partly used or unused 
drug supply before approval to do so by the sponsor.  At the conclusion of the study and as 
appropriate during the study, the investigator (or a designated pharmacist) will return all used 
and unused drug containers, drug labels, and a copy of the completed drug disposition form 
to the sponsor’s CRA.

Family-Based Lifestyle Program
Program Overview
All subjects and their caregivers (participating parent or guardian) in Study 403 will 
participate in a standardized weight management program for adolescents consisting of 
multicomponent behavior therapy.  The therapy will focus on healthy eating, physical 
activity, and lifestyle changes that will facilitate weight loss and weight-loss maintenance. 
The role of the caregivers is to support their child or adolescents’ lifestyle changes and their 
taking of study medication.
The objectives of this program are as follows:

Develop a weight management program for all Belviq XR study participants and their 
caregivers (caregivers are instructed in methods to support their adolescents’ progress 
but caregivers are themselves not instructed to lose weight or take medication)

Standardize the weight management program across all study sites

Maximize participant retention

Promote participant’s adherence to both taking study medication and following the 
lifestyle program

Appendix 3
Pharmacodynamic and Other Biomarker Research
Subjects enrolled in this clinical study will have biologic samples collected for 
pharmacodynamic (PD), and other biomarker analysis.  These samples may be used for 
discovery or validation to identify biomarkers that may be used for exploratory evaluation of 
response or safety-related outcomes as well as for use in diagnostic development.
The pharmacogenetics (PG) samples may be used to identify genetic factors that may 
influence a subject’s exposure to the study drug, as well as genetic factors that may have an 
effect on clinical response or potential adverse events (AEs) related to study treatment, and to 
explore the role of genetic variability in response.  Samples may be analyzed to determine a 
subject’s genotypes or sequence for a number of genes or non-coding regulatory regions.  
The research may include the investigation of polymorphisms in genes that are likely to 
influence the study drug pharmacokinetic (PK) or therapeutic response.
Collection of the PD, and other biomarker samples will be bound by the sample principles 
and processes outlined in the main study protocol.  Sample collection for PD, PG, and other 
biomarker analysis is required as per the study protocol unless the collection and use of the 
samples is prohibited by specific country laws.
Sample Collection and Handling
The samples will be collected according to the study flow chart.  If, for operational or 
medical reasons, the genomic DNA blood sample cannot be obtained at the prespecified visit, 
the sample can be taken at any study center visit at the discretion of the investigator and site 
staff.
Security of the Samples, Use of the Samples, Retention of the Samples
Sample processing, for example DNA or RNA extraction, genotyping, sequencing, or other 
analysis will be performed by a laboratory under the direction of the sponsor.  Processing, 
analysis, and storage will be performed at a secure laboratory facility to protect the validity 
of the data and maintain subject privacy.
Samples will only be used for the purposes described in this protocol.  Laboratories 
contracted to perform the analysis on behalf of the sponsor will not retain rights to the 
samples beyond those necessary to perform the specified analysis and will not transfer or sell 
those samples.  The sponsor will not sell the samples to a third party.
Samples will be stored for up to 15 years after the completion of the study (defined as 
submission of the clinical study report to the appropriate regulatory agencies).  At the end of 
the storage period, samples will be destroyed.  Samples may be stored longer if a health 
authority (or medicinal product approval agency) has active questions about the study.  In 
this special circumstance, the samples will be stored until the questions have been adequately 
addressed.

It is possible that future research and technological advances may identify genomic variants 
of interest, or allow alternative types of genomic analysis not foreseen at this time.  Because 
it is not possible to prospectively define every avenue of future testing, all samples collected 
will be single or double coded (according to the ICH E15 guidelines) in order to maintain 
subject privacy.
Right to Withdraw
If, during the time the samples are stored, a participant would like to withdraw his/her 
consent for participation in this research, Eisai will destroy the samples.  Information from 
any assays that have already been completed at the time of withdrawal of consent will 
continue to be used as necessary to protect the integrity of the research project.
Subject Privacy and Return of Data
No subject-identifying information (eg, initials, date of birth, government identifying 
number) will be associated with the sample.  All PD and other biomarker samples will be 
single coded.  Genomic DNA samples used to explore the effects on PK, treatment response, 
and safety will be single coded.  Genomic DNA samples that will be stored for long-term use 
(defined as 15 years after the completion of the study) will be double coded.  Double coding 
involves removing the initial code (subject ID) and replacing with another code such that the 
subject can be re-identified by use of 2 code keys.  The code keys are usually held by 
different parties.  The key linking the sample ID to the subject number will be maintained 
separately from the sample.  At this point, the samples will be double-coded, the first code 
being the subject number.  Laboratory personnel performing genetic analysis will not have 
access to the “key.”  Clinical data collected as part of the clinical trial will be cleaned of 
subject identifying information and linked by use of the sample ID “key.”
The sponsor will take steps to ensure that data are protected accordingly and confidentiality 
is maintained as far as possible.  Data from subjects enrolled in this study may be analyzed 
worldwide, regardless of location of collection.
The sponsor and its representatives and agents may share coded data with persons and 
organizations involved in the conduct or oversight of this research.  These include:
•
Clinical research organizations retained by the sponsor 
•
Independent ethics committees or institutional review boards that have responsibility for 
this research study 
•
National regulatory authorities or equivalent government agencies
At the end of the analysis, results may be presented in a final report which can include part or 
all of the coded data, in listing or summary format.  Other publication (eg, in peer-reviewed

scientific journals) or public presentation of the study results will only include summaries of 
the population in the study, and no identified individual results will be disclosed.
Given the research nature of the PD, PG, and other biomarker analysis, it will not be possible 
to return individual data to subjects.  The results that may be generated are not currently 
anticipated to have clinical relevance to the patients or their family members.  Therefore, 
these results will not be disclosed to the patients or their physicians.
If at any time, PD, PG, or other biomarker results are obtained that may have clinical 
relevance, Institutional Review Board review and approval will be sought to determine the 
most appropriate manner of disclosure and to determine whether or not validation in a 
Clinical Laboratory Improvement Amendments-certified setting will be required.  Sharing of 
research data with individual patients should only occur when data have been validated by 
multiple studies and testing has been done in Clinical Laboratory Improvement 
Amendments-approved laboratories.

of achieving ≥5% and ≥10% reduction in BMI from baseline at Week 52, using population 
PK/pharmacodynamics (PD) modeling
Study Design
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in obese 
adolescents, age 12 to 17 years old.  Approximately 360 subjects will be randomized in a 1:1 ratio to 
BELVIQ 20 mg QD (180 subjects) and placebo (180 subjects).  Subjects will receive BELVIQ 20 mg 
or placebo QD for up to 52 weeks. Throughout the duration of the study, subjects will be encouraged 
to adhere to a diet and exercise program.
The study will consist of 2 phases: Prerandomization and Randomization.  The Prerandomization 
Phase will last up to 30 days and consist of 1 visit during which subjects will be screened for 
eligibility.  The Randomization Phase consists of a Treatment Period and a Follow-up Period.  The 
Treatment Period will last for a maximum of 52 weeks, with visits at Weeks 1, 5, 8, 12, 20, 28, 36,
44, and 52, and a Follow-up Period extending from the end-of-treatment (EOT) visit to the 
end-of-study (EOS) visit.  
All subjects will continue in the study until the 52-week evaluation is completed.  Subjects who 
discontinue treatment prematurely will be followed up until study completion.  
Number of Subjects
Approximately 700 subjects will be screened to provide 360 randomized subjects.

Pharmacokinetic Assessments
Plasma lorcaserin concentrations will be measured at Weeks 12, 28, 36, and 52 for analysis of 
population PK.  At Weeks 12, 24, and 52, subjects will be instructed to take their morning dose at the 
clinic.  Two blood samples for determination of plasma concentrations of lorcaserin will be taken at 
each of these visits: predose (within 30 minutes prior to dosing) and within 1 to 3 hours postdose.  At 
the Week 36 visit, subjects will take the morning dose at home, and 1 sample for determination of 
plasma concentrations of lorcaserin will be collected at the investigational site within 4 to 6 hours 
postdose.
Pharmacodynamic Assessments

Proportion (%) of patients achieving ≥5% and ≥10% BMI reduction

BMI change from baseline
Other pharmacodynamic endpoints will be considered based on the data at the end of the study to 
explore their relationships with exposure to lorcaserin
Pharmacogenomic/Pharmacogenetic Assessments
At the time of randomization, when applicable, a blood sample will be taken for potential 
investigation of genetic variability associated with genotypes relating to response to BELVIQ, weight 
loss, susceptibility to diabetes, and their associated risk factors.
Safety Assessments
Safety assessments will consist of monitoring and recording all adverse events (AEs) and serious 
adverse events (SAEs), laboratory evaluation for hematology, blood chemistry, and urine values; 
neuropsychiatric events, periodic measurement of vital signs, and performance of physical 
examinations. Study drug effect on adolescent growth will be evaluated using the US Center for


The proportion of subjects achieving ≥10% BMI reduction will be analyzed using logistic 
regression model with treatment and site as factors, and baseline BMI as a covariate.  
Comparison between BELVIQ and placebo will be made at Week 52.  The FAS analysis set 
will be used for this analysis.  Sensitivity analysis will be conducted treating subjects with 
missing BMI data at Week 52 as nonresponders (did not achieve ≥10% BMI reduction).

A logistic regression model with treatment and site as factors will be used to analyze the 
following endpoints.  Comparison between BELVIQ and placebo will be made at Week 52.

o
Proportion (%) of subjects with confirmed  pre-hypertension or primary 
hypertension
o
Proportion (%) of subjects with dyslipidemia
o
Proportion (%) with metabolic syndrome that met at least 2 IDF criteria
Pharmacokinetic Analyses
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear 
mixed 
effects 
modeling. 
The 
effect 
of 
covariates, 
such 
as 
baseline 
characteristics/demographics, on PK will be explored. Derived exposure parameters such as the 
maximum observed concentration (Cmax) and the area under the concentration-time curve from time 
zero to 24 hours at steady-state (AUC0-24,ss) will be calculated from the final PK model using 
individual posterior estimates of the PK parameters and from dosing history. The PK analysis set 
will be used for this analysis. 
Pharmacodynamic Analyses
Proportion (%) of patients achieving ≥5% and ≥10% BMI reduction, and BMI change from baseline 
will be assessed as the PD analysis.  The PD analysis set will be used for this analysis.
Other assessments (ie, BMI change, percentage of BMI change, proportion [%] of patients achieving 
≥10% BMI reduction, and waist circumference from baseline) will also assessed as PD analysis.  The 
PK/PD analysis set will be used for this analysis.
Pharmacokinetic/Pharmacodynamic Analyses
Population PK/PD modeling will be used to explore the relationship between exposure to BELVIQ
and response, including but not limited to change in BMI from baseline and the probability of 
achieving ≥5% and ≥10% change in BMI from baseline to Week 52.  Additionally, exposure-safety 
relationships for select safety parameters may be explored graphically.  Any emergent relationship 
may be modeled as appropriate.  Any parameters based on the study data may be considered for 
exploratory assessment for its relationship to PK.
Pharmacogenomic/Pharmacogenetic Analyses
A blood sample for potential investigation of genetic variability associated with genotypes relating to 
response to BELVIQ, weight loss, susceptibility to diabetes, and their associated risk factors will be 
taken at the time of randomization in the study, where applicable.
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  The incidence of AEs (including 
changes from baseline in physical examination),
suicidal ideation/behavior (C-SSRS), 
neuropsychiatric events, out-of-normal-range laboratory safety test variables, along with change from

baseline in laboratory safety test variables, and vital sign measurements at the end of treatment will 
be summarized by treatment group using descriptive statistics.
Interim Analyses
Not applicable
Sample Size Rationale
A sample size of 360 subjects in a 1:1 ratio (n=180 in the BELVIQ 20-mg QD treatment group: 
n=180 in the placebo group) will have 90% power to detect a 20% difference between treatment 
groups in the proportions of subjects with at least 5% reduction in BMI, assuming the placebo 
response is 20%, using a 2-sided test and α=0.05, assuming a 35% dropout rate. The assumption is 
based on lorcaserin adult Phase 3 and adolescent studies with orlistat and sibutramine.

ETHICS
5.1
Institutional Review Boards/Independent Ethics Committees
The protocol, informed consent form (ICF), and appropriate related documents must be 
reviewed and approved by an Institutional Review Board (IRB) or Independent Ethics 
Committee (IEC) constituted and functioning in accordance with International Conference on 
Harmonisation Good Clinical Practice (ICH E6), Section 3, and any local regulations (eg, 
Federal Regulations, Title 21 CFR Part 56).  Any protocol amendment or revision to the ICF 
will be resubmitted to the IRB/IEC for review and approval, except for changes involving 
only logistical or administrative aspects of the study (eg, change in clinical research associate 
[CRA]), change of telephone number[s]).  Documentation of IRB/IEC compliance with the 
ICH E6 and any local regulations regarding constitution and review conduct will be provided 
to the sponsor.
A signed letter of study approval from the IRB/IEC chairman must be sent to the principal 
investigator (PI) with a copy to the sponsor before study start and the release of any study 
drug to the site by the sponsor or its designee (ICH E6, Section 4.4).  If the IRB/IEC decides 
to suspend or terminate the study, the investigator will immediately send the notice of study 
suspension or termination by the IRB/IEC to the sponsor.
Study progress is to be reported to IRB/IECs annually (or as required) by the investigator or 
sponsor, depending on local regulatory obligations.  If the investigator is required to report to 
the IRB/IEC, he/she will forward a copy to the sponsor at the time of each periodic report.  
The investigator(s) or the sponsor will submit, depending on local regulations, periodic 
reports and inform the IRB/IEC of any reportable adverse events (AEs) per ICH guidelines 
and local IRB/IEC standards of practice.  Upon completion of the study, the investigator will 
provide the IRB/IEC with a brief report of the outcome of the study, if required.
At the end of the study, the sponsor should notify the IRB/IEC and Competent Authority 
(CA) within 90 days.  The end of the study will be the date of the last study visit for the last 
subject in the study.  The sponsor should also provide the IRB/IEC with a summary of the 
study’s outcome.
In the case of early termination temporary halt of the study, the investigator should notify the 
IRB/IEC and CA within 15 calendar days, and a detailed written explanation of the reasons 
for the termination/halt should be given.

INTRODUCTION
7.1
Indication
Obesity
Obesity has become a global epidemic as well as a serious public health concern.  In the 
United States (US), the prevalence of obesity in adolescents between 12 and 19 years of age 
has almost doubled over the past 2 decades.  The rate increased from 10.5% between 1988 
and 1994 to 20.5% between 2011 and 2012 (CDC/NCHS, 2013).  Obesity in adolescents, 
defined in the US as ≥95th percentile in gender- and age-specific body mass index (BMI), 
continues to grow at an alarming rate in the US and globally.  Based on data (Wang and 
Lobstein, 2006) using various criteria for the definition of obesity that included more than 
30 countries in Europe, North America, Asia, and West Pacific countries, prevalence rates in 
these countries also have increased significantly, comparable to that in the US.   
Adolescent obesity has many negative implications for both the health and well-being of the 
individual as well as for society.  These include increased susceptibility to a host of diseases, 
chronic health disorders, psychological disorders, and premature death (Flegal, et al., 2005; 
Rofey, et al., 2009).  Increases in the prevalence of overweight and obese adolescents may 
result in a decrease in life expectancy for the first time in 200 years.
As a result, there is a significant impact to the cost of healthcare.  It is estimated that medical 
costs due to overweight adolescents are approximately more than $14 billion per year in the 
US (Trasande, et al., 2009).  Obesity-related medical costs in general are expected to rise 
significantly, especially because today’s obese children are likely to become tomorrow’s 
obese adults.
Current approaches to weight management include lifestyle modification, pharmacotherapy, 
and invasive bariatric procedures.  Lifestyle modification involves a combination of diet, 
exercise, and behavioral change, and is the preferred and essential strategy for weight 
management in obese and overweight individuals.  Although lifestyle modification can be 
very efficacious in some patients, adherence to the prescribed regimens is often poor.  As 
such, lifestyle modification alone is often not adequate and the weight loss is often transient.  
On the other hand, bariatric surgery and various other invasive procedures are generally 
reserved for the severely obese population.

Pharmacotherapy can play a significant role in weight management programs and is often 
combined with lifestyle modification to enhance weight loss beyond that which is normally 
achieved with diet and exercise alone.  Current pharmacotherapies offer the potential to 
significantly augment weight loss when combined with diet and exercise.
The current standard of care for treatment of obesity in pediatric subjects ranges from 
lifestyle intervention in children younger than 8 years old to use of pharmacotherapy in 
adolescents older than 12 years (McGovern, 2008; Spear, 2007).  Xenical® (orlistat) is 
currently the only product available for weight control in obese adolescent patients 12 to 
16 years of age; however, it is associated with gastrointestinal side effects (Xenical PI. 2006), 
and the treatment effect of Xenical is modest. In a study that included 539 obese adolescents 
with BMI >97th percentile, Xenical demonstrated a 0.86 BMI reduction relative to placebo 
after 52 weeks of treatment (-0.55 BMI in the Xenical treatment group versus +0.31 BMI in 
the placebo group) (FDA, 2003; Chanoine JP, 2005). 
7.1.1
APD356/BELVIQ (lorcaserin hydrochloride)
7.1.1.1
Mechanism of Action
BELVIQ® is a selective serotonin 2c receptor agonist which was approved by the US Food 
and Drug Administration (FDA) on 27 June 2012 as an adjunct to a reduced calorie diet and 
increased physical activity for chronic weight management in adult patients with a BMI 
≥30 kg/m2 (obese), or adult patients with a BMI ≥27 kg/m2 (overweight) in the presence of at 
least 1 weight-related comorbid condition. 
7.1.1.2
Clinical Experience with APD356/BELVIQ (lorcaserin hydrochloride)
The Phase 3 clinical evaluation of BELVIQ in clinical studies of more than 7700 adult 
subjects, including 604 subjects with type 2 diabetes mellitus (T2DM), demonstrated 
clinically meaningful efficacy, and a safety profile that includes minimal and easily managed 
risks.  Additionally, in studies APD356-009 and APD356-011, more than 2% of the subjects
developed biochemical criteria for T2DM during the study (hemoglobin A1c [HbA1c] ≥6.5).  
The proportion of subjects developing new criteria for diabetes was 1.6-fold greater in the 
placebo as compared with the BELVIQ 20 mg once daily (QD) group (P=0.003).  In the 
pooled efficacy analyses, the BELVIQ 20 mg QD dose met the following prespecified 
endpoints:

A significantly greater proportion of subjects taking BELVIQ (47%) lost ≥5% of 
baseline body weight at 1 year as compared to placebo (23%).  A significantly greater 
proportion of subjects taking BELVIQ (22.4%) lost ≥10% of baseline body weight at 
1 year as compared to placebo (8.7%). 

The mean weight loss at 1 year in subjects taking BELVIQ (-5.8 kg) was significantly 
greater than that in subjects taking placebo (-2.5 kg).

FINAL:  16 Apr 2015
Page 22 of 75

Glycemic benefits were also demonstrated by a 0.5% HbA1c reduction among subjects 
with T2DM and reduction in incidence of new diabetes in the prediabetes population 
compared to placebo
In adolescent obese populations, it is anticipated that BELVIQ will result in similar effects. 
As part of the FDA post marketing requirements, this study is designed to characterize the 
efficacy and safety of BELVIQ in adolescent obese populations in the US; it is also intended 
to support an indication for chronic weight management for obese adolescents.
7.2
Study Rationale
There is no specific FDA guidance for the approval of a weight loss product in adolescents.  
In adults, the Division’s 2007 draft Guidance for Industry Developing Products for Weight 
Management indicate that the product needs to satisfy either of the following mean or 
categorical criteria after 1 year of treatment:

The difference in mean weight loss between the active-product and placebo-treated 
groups is at least 5% and the difference is statistically significant, or

The proportion of subjects who lose ≥5% of baseline body weight in the 
active-product group is at least 35%, is approximately double the proportion of 
subjects in the placebo-treated group who lose ≥5% of baseline body weight, and the 
difference between groups is statistically significant.
The FDA awarded a weight management indication for BELVIQ based on Phase-3 study 
results which achieved the categorical criteria. In a Phase 3 study, a significantly greater 
proportion of subjects taking BELVIQ (47%) lost ≥5% of baseline body weight at 1 year as 
compared to placebo (23%).  It is anticipated that a similar effect will be demonstrated in an 
obese adolescent population, where weight loss will be assessed using BMI (kg/m2)
measurements to account for growth. In this study, the objective is to demonstrate that 
BELVIQ will achieve a greater proportion (%) of subjects with ≥5% reduction in BMI during 
52 weeks of treatment with BELVIQ 20 mg administered QD compared to placebo in obese 
adolescents. 
There are limited clinical studies of weight loss products in obese adolescent populations. In 
the Phase 3 orlistat study mentioned above, the proportion of subjects who lost at least 
5% body weight is relatively low. At the end of the study at Week 52, only 26.5% of 
subjects achieved a 5% or more BMI reduction compared to 15.7% in the placebo group.  In 
a sibutramine Phase-3 study in obese adolescents, a substantially higher proportion of 
subjects (69%) treated with sibutramine achieved at least 5% BMI reduction compared to 
21% of subjects in the placebo group (Berkowitz. 2006).  Unlike the weight loss effect of 
BELVIQ in adults and sibutramine in adolescents, subjects in the orlistat study started to 
increase their BMI after 6 months of treatment (Chanoine, 2005).
In this proposed study, it is assumed that 20% of subjects in the placebo group will achieve at 
least a 5% reduction in BMI, based mostly on placebo group results in the above-mentioned
sibutramine study (21%) and the BELVIQ Phase-3 studies (23%).

FINAL:  16 Apr 2015
Page 23 of 75
After 1 year, pooled analyses from the two Phase 3 BELVIQ pivotal studies showed that
47% of the BELVIQ-treated subjects achieved at least a 5% reduction in weight compared 
with 23% of the placebo subjects.  This between-group difference of 24.5% is the basis for 
the conservative assumption of a 20% effect size in the current study. 
In addition, the total sample size of 360 subjects will be adequate to assess safety and 
exposure, based on previous adolescent studies with weight management products (orlistat 
and sibutramine) (FDA, 2003; Chanoine,
2005; Berkowitz,
2006), and other 
metabolic/dyslipidemia medication products (ezetimibe/simvastatin) (FDA, 2007).

STUDY OBJECTIVES
8.1
Primary Objective
The primary objective of the study is to demonstrate weight loss efficacy by achieving a 
greater proportion (%) of subjects with a 5% or greater reduction in BMI during 52 weeks of 
treatment with BELVIQ 20 mg administered once daily (QD) compared to placebo in obese 
adolescents.
8.2
Secondary Objectives
The secondary objectives of the study are:
1. To demonstrate weight loss efficacy by achieving a greater proportion (%) of subjects 
with ≥5% reduction in BMI (kg/m2) after an initial 12 weeks of treatment with
BELVIQ 20 mg administered QD compared to placebo in obese adolescents
2. To demonstrate weight loss effect by mean change in BMI during 52 weeks of 
treatment with BELVIQ 20 mg administered QD compared to placebo in obese 
adolescents.
3. To demonstrate the effects of treatment with BELVIQ 20 mg QD by assessing:

Other weight loss effects (eg, proportion [%] of subjects achieving ≥10% BMI 
reduction, and change in waist circumference) at the end of 52 weeks of treatment

Effects on glycemia, insulin levels, and HOMA-IR during 52 weeks of treatment

Changes in cardiovascular risk factors associated with obesity (ie, hypertension, 
dyslipidemia, Metabolic Syndrome) during 52 weeks of treatment
4. To assess the safety of BELVIQ, including the effects on growth by growth chart, 
sexual maturation measured by Tanner Staging scores, and signal of suicidal 
ideation/behavior with the Columbia-Suicide Severity Rating Scale (C-SSRS) 
5. To assess the pharmacokinetics (PK) of lorcaserin in obese adolescents using 
population PK modeling
6. To 
explore 
potential 
relationships 
between 
exposure 
to 
lorcaserin 
and 
pharmacodynamic (PD)  parameters including but not limited to reduction from 
baseline in BMI and probability of achieving ≥5% and ≥10% reduction in BMI from 
baseline at Week 52, using population PK/pharmacodynamics (PD) modeling

INVESTIGATIONAL PLAN
9.1
Overall Study Design and Plan
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in 
obese adolescents, age 12 to 17 years old.  Approximately 360 subjects will be randomized in 
a 1:1 ratio to BELVIQ 20 mg QD (180 subjects) and placebo (180 subjects).  Subjects will 
receive BELVIQ 20 mg or placebo QD for up to 52 weeks. Throughout the duration of the 
study, subjects will be encouraged to adhere to a lifestyle modification program that includes 
diet and exercise counseling (see Appendix 2).  
The study will consist of 2 phases: Prerandomization and Randomization.  The 
Prerandomization Phase will last up to 30 days and consists of 1 visit during which subjects 
will be screened for eligibility.  The Randomization Phase consists of a Treatment Period and 
a Follow-up Period.  The Treatment Period will last for a maximum of 52 weeks, with visits 
at Weeks 1, 5, 8, 12, 20, 28, 36, 44, and 52; the Follow-up Period will extend from the 
end-of-treatment (EOT) visit to the end-of-study (EOS) visit.  
All subjects will continue in the study until the 52 week evaluation is completed.  Subjects 
who discontinue treatment prematurely will be followed up until study completion.  
9.1.1
Prerandomization/Pretreatment Phase
Screening will occur during the Prerandomization Phase at Visit 1.
9.1.1.1
Screening Period
The purpose of the Screening Period is to obtain the informed consent and to establish 
protocol eligibility.  Procedures to be followed when obtaining informed consent are detailed 
in Section 5.3.  Screening period assessments and timing thereof are shown in Section 9.5.2.
9.1.2
Randomization/Treatment Phase
The Randomization Phase will consist of 2 periods, the Treatment Period and the Follow-up 
Period. The Treatment Period assessments and timing thereof are shown in Section 9.5.2.
9.1.3
Extension Phase
Not applicable
9.2
Discussion of Study Design, Including Choice of Control Groups
The proposed dose and dosing frequency in this study is 20 mg QD which is the 
FDA-approved regimen for obesity in adults. The PK parameters of a single 10-mg dose of 
BELVIQ were evaluated in healthy, adolescent obese subjects in Study APD356-025. 
Overall, the PK parameters of BELVIQ and its main metabolites, M1 and M5, were similar 
to those in adults.  Following a single, oral administration of BELVIQ 10 mg to a total of

Page 26 of 75
8 healthy adolescent (age 12 to 17 years, inclusive) obese subjects, the mean maximum 
concentration observed (Cmax) and the area under the concentration- time curve from time 
zero to infinity (AUC(0-inf) were 36.5 ng/mL and 464 hr·ng/mL, respectively.  The mean 
BELVIQ terminal phase half-life (t1/2) was 9.70 hours, similar to that observed in adults, thus 
supporting a similar dosing frequency (ie, once daily) in adolescent subjects.
The targeted study population comprises 360 obese adolescents 12 to 17 years of age, 
inclusive. 
Obese adolescents will be identified using gender- and age-specific BMI measurement.  
Obesity in adolescents is defined by US Expert committee recommendations as BMI ≥95th 
percentile (Barlow, 2007). 
Randomization will be used in this study to avoid bias in the assignment of subjects to 
treatment, to increase the likelihood that known and unknown subject attributes (eg, 
demographics and baseline characteristics) are balanced across treatment groups, and to 
ensure the validity of statistical comparisons across treatment groups.  Blinding to treatment 
will be used to reduce potential bias during data collection and evaluation of endpoints
9.3

Study drug must be stored as instructed on the study drug label and in accordance with the
DEA Regulations for Schedule IV Controlled Drugs (US sites). Study drug must be kept
in a secure location as required by DEA regulations and carefully stored at the study site
within its original container.
The investigator (or pharmacist, as appropriate) must maintain records of the delivery
of the study drug to the study site, the inventory at the site, use for each subject, and return
of the study drug to a delegate of the sponsor. Total study site accountability will be
conducted at the end of the study and the investigator must explain any discrepancies.
A Drug Dispensing Log must be kept current and should contain at least the
following information:
•
Identification (subject ID number and initials) of the subject to whom the study drug 
was dispensed
•
The dates and unique kit/carton identifiers for dispensed study drug
•
Initial inventory on receipt of drug at the site
•
Final inventory on completion of the study
All records and inventory must be available for inspection by the clinical study
monitor.
9.4.2.4
Storage Conditions
Where applicable, investigational product will be stored in accordance with the DEA 
Regulations for Scheduled III - V Drugs and labeled storage conditions.  Temperature 
monitoring is required at the storage location to ensure that the study drug is maintained 
within an established temperature range.  The investigator or designee is responsible for 
ensuring that the temperature is monitored throughout the total duration of the study and that 
records are maintained; the temperature should be monitored continuously by using either an 
in-house validated data acquisition system, a mechanical recording device, such as a 
calibrated chart recorder, or by manual means, such that minimum and maximum 
thermometric values over a specific time period can be recorded and retrieved as required.
9.4.3
Method of Assigning Subjects to Treatment Groups
Subjects will be assigned to treatments based on a computer-generated randomization 
scheme that will be reviewed and approved by an independent statistician.  The 
randomization scheme and identification for each subject will be included in the final clinical 
study report for this study.
After the Prerandomization Phase, subjects will be randomized to 1 of 2 treatment groups in 
a ratio of 1:1.  Each treatment group will receive either BELIVIQ or placebo QD.  
Randomization will be performed centrally by an interactive voice and/or web response

system (IxRS).  The IxRS or clinical supply vendor will generate the randomized 
identification numbers to be included on study packaging.  Upon signature of the ICF, the 
investigator or designee will access the IxRS to register the subject information.  At 
Randomization, the IxRS will assign each subject a unique randomization number.  At each 
subsequent visit during the Treatment Period and Follow-up Period, the investigator or 
designee will access IxRS to obtain dispensing information and to register the subject’s visit. 
9.4.4
Selection and Timing of Dose for Each Subject
Subjects should take the study medication once daily, and be encouraged to take the study 
medication with an adequate amount of water (8 oz. or 240 mL).
9.4.5
Blinding
During the Randomization Phase, subjects and all personnel involved with the conduct and 
interpretation of the study, including investigators, site personnel, and sponsor staff will be 
blinded to the treatment codes.  Randomization data will be kept strictly confidential, filed 
securely by an appropriate group with the sponsor or CRO and accessible only to authorized 
persons (eg, Eisai Global Safety) until the time of unblinding, per the SOP.
A master list of all treatments and the subject numbers associated with them will be 
maintained in a sealed envelope by the clinical supply vendor, the IxRS vendor, and the 
sponsor.  In the event that emergency conditions require knowledge of the study treatment 
given, the blind may be broken via the code breaker facility within the IxRS.  Emergency 
procedures for revealing drug codes are given in Section 9.5.4.5.  If possible, before breaking 
the blind, the investigator should consult with the sponsor or designee to ascertain the 
necessity of breaking the code.  
9.4.6
Prior and Concomitant Therapy
Any medication (including OTC medications) or therapy administered to the subject during 
the study (starting at the date of informed consent) will be recorded on the Prior & 
Concomitant Medication CRF or Non-Pharmacological Procedures CRF.  The investigator 
will record on the Adverse Event CRF any AE for which the concomitant medication/therapy 
was administered. If the concomitant medication/therapy is being administered for a medical 
condition present at the time of entry into the study, the investigator will record the medical 
condition on the Medical History and Current Medical Condition CRF’
Other products intended for weight loss including prescription drugs, OTC drugs, and herbal 
preparations are prohibited as concomitant medications.  Any of the following serotonergic 
agents in combination with BELVIQ is prohibited, with the exception that OTC cold 
medicines containing dextromethorphan can be used for up to 7 days and study medication is 
temporarily stopped for that time period (and should be resumed the next day after the OTC 
cold medicine is stopped).

9.5.1.5.1
ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered an investigational product.  An AE does not necessarily have a causal 
relationship with the medicinal product.  For this study, the study drug is BELVIQ 
(lorcaserin hydrochloride). 
The criteria for identifying AEs in this study are:
•
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or 
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE)
•
Any new disease or exacerbation of an existing disease 
•
Any deterioration in nonprotocol-required measurements of a laboratory value or other 
clinical test (eg, electrocardiogram (ECG) or x-ray) that results in symptoms, a change in 
treatment, or discontinuation of study drug
•
Recurrence of an intermittent medical condition (eg, headache) not present pretreatment 
(Baseline)
•
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of study drug, or withholding 
of study drug, whether prescribed in the protocol or not.
All AEs observed during the study will be reported on the Screening Disposition CRF.  All 
AEs, regardless of relationship to study drug or procedure, should be collected beginning 
from the time the subject signs the study ICF through the last visit in the Treatment Phase.
Subjects who fail screening primarily due to AE(s) must have the AE(s) leading to screen 
failure reported on the Screening Disposition CRF.  Serious AEs will be collected for 30 days 
after the last dose.
Page 859 of 897

Clinical Study Protocol
APD356-A001-403
Eisai
FINAL:  16 Apr 2015
Page 38 of 75
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute 
an AE.  Medical and scientific judgment should be exercised in deciding whether an isolated 
laboratory abnormality should be classified as an AE.  Any laboratory abnormality 
considered to constitute an AE should be reported on the Adverse Event CRF. 
Abnormal ECG (QTc) results, if not otherwise considered part of a clinical symptom that is 
being reported as an AE, should be considered an AE if the QTc interval is >450 ms and 
there is an increase of >60 ms from baseline.  Any ECG abnormality that the investigator 
considers as an AE should be reported as such.
It is the responsibility of the investigator to review the results of the C-SSRS in all subjects 
and determine if any result constitutes an AE.  Medical and scientific judgment should be 
exercised in deciding whether an isolated suicidality rating scale response should be 
classified as an AE (see Section 9.5.1.5.8 for a description of the C-SSRS).
All AEs must be followed for 30 days after the subject’s last dose, or until resolution, 
whichever comes first.  All SAEs must be followed to resolution or, if resolution is unlikely, 
to stabilization.
Every effort must be made by the investigator to categorize each AE according to its 
severity and its relationship to the study treatment.
Assessing Severity of Adverse Events
Adverse events will be graded on a 3-point scale (mild, moderate, severe) and reported in the 
detail indicated on the CRF.  The definitions are as follows:
Mild
Discomfort noticed, but no disruption of normal daily activity
Moderate Discomfort sufficient to reduce or affect normal daily activity
Severe
Incapacitating, with inability to work or to perform normal daily activity
The criteria for assessing severity are different than those used for seriousness (see
Section 9.5.1.5.2 for the definition of an SAE).
Assessing Relationship to Study Treatment
Items to be considered when assessing the relationship of an AE to the study treatment are:
•
Temporal relationship of the onset of the event to the initiation of the study treatment
•
The course of the event, especially the effect of discontinuation of study treatment or 
reintroduction of study treatment, as applicable
•
Whether the event is known to be associated with the study treatment or with other 
similar treatments
Page 860 of 897

Clinical Study Protocol
APD356-A001-403
Eisai
FINAL:  16 Apr 2015
Page 39 of 75
•
The presence of risk factors in the study subject known to increase the occurrence of 
the event
•
The presence of nonstudy, treatment-related factors that are known to be associated 
with the occurrence of the event
Classification of Causality
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question:
Is there a reasonable possibility that the study drug caused the AE?
Yes (related)
A causal relationship between the study drug and the AE is a reasonable 
possibility.
No (not related) A causal relationship between the study drug and the AE is not a 
reasonable possibility.
9.5.1.5.2
SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
An SAE is any untoward medical occurrence that at any dose:
•
Results in death
•
Is life-threatening (ie, the subject was at immediate risk of death from the AE as it 
occurred; this does not include an event that, had it occurred in a more severe form or 
was allowed to continue, might have caused death)
•
Requires inpatient hospitalization or prolongation of existing hospitalization
•
Results in persistent or significant disability/incapacity
•
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug)
Other important medical events that may not be immediately life-threatening or result in 
death or hospitalization but, when based on appropriate medical judgment, may jeopardize 
the subject or may require intervention to prevent one of the outcomes in the definition of 
SAE listed above should also be considered SAEs.  Medical and scientific judgment should 
be exercised in deciding whether expedited reporting is appropriate in such situations. 
For this study, the following events should always be considered serious and reported as an 
important medical event if it does not meet other serious criteria:
•
Serotonin syndrome (must have at least one of the following: Spontaneous clonus; 
Inducible clonus PLUS agitation or diaphoresis; Ocular clonus PLUS agitation or 
diaphoresis; Tremor PLUS hyperreflexia; Hypertonia PLUS temperature above 38ºC 
PLUS ocular clonus or inducible clonus)
•
Psychosis, suicidal behavior

•
Priapism
•
New onset valvular heart disease
•
New onset PH
•
Malignant neoplasms, with the exception of basal cell and squamous cell carcinomas 
of the skin
•
Fibroadenomas of the breast or ductal carcinoma in situ
In addition to the above, events associated with special situations include pregnancy or 
exposure to study drug through breastfeeding; AEs associated with study drug overdose, 
misuse, abuse, or medication error.  These events associated with special situations are to be 
captured using the SAE procedures but are to be considered as SAEs only if they meet one of 
the above criteria.  All AEs associated with special situations are to be reported on the CRF 
whether or not they meet the criteria for SAEs.  
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization.
The following hospitalizations are not considered to be SAEs because there is no “adverse 
event” (ie, there is no untoward medical occurrence) associated with the hospitalization:
•
Hospitalizations for respite care 
•
Planned hospitalizations required by the protocol
•
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed post study drug administration)
•
Hospitalization for administration of study drug or insertion of access for 
administration of study drug
•
Hospitalization for routine maintenance of a device (eg, battery replacement) that was 
in place before study entry
9.5.1.5.3
LABORATORY MEASUREMENTS

Clinical laboratory tests during the study will be performed by a central laboratory.  All 
blood and urine samples will be collected and sent to the central laboratory on the day of 
collection unless otherwise instructed.  In cases of a safety concern, blood samples will be 
split (or 2 samples drawn) to allow a local laboratory analysis in addition to the central 
laboratory.  
A laboratory abnormality may meet the criteria to qualify as an AE as described in this 
protocol (see Section 9.5.1.5.1) and the CRF Completion Guidelines.  In these instances, the 
AE corresponding to the laboratory abnormality will be recorded on the Adverse Event CRF.
9.5.1.5.4
VITAL SIGNS AND WEIGHT MEASUREMENTS
Vital sign measurements (ie, systolic and diastolic blood pressure [BP] [mmHg], pulse [beats 
per minute], respiratory rate [per minute], body temperature [in centigrade]), and weight (kg) 
will be obtained as designated in the Schedule of Procedures/Assessments (Table 2) by a 
validated method.  Blood pressure and pulse will be measured after the subject has been 
sitting for 5 minutes.  All BP measurements should be performed on the same arm, 
preferably by the same person. 
When vital signs are to be obtained concurrently with PK or other blood samples, the vital 
sign measurements will be performed prior to drawing blood samples in order to maximize 
the accuracy of blood sampling times while minimizing the potential effects of blood 
drawing on recordings obtained during safety assessments.

Reporting of Serious Adverse Events, Pregnancy, and Events Associated 
with Special Situations
9.5.4.1
Reporting of Serious Adverse Events
All SERIOUS ADVERSE EVENTS, regardless of their relationship to study treatment, 
must be reported on a completed SAE form by email or fax as soon as possible but no 
later than 1 business day from the date the investigator becomes aware of the event.
Serious adverse events, regardless of causality assessment, must be collected through the 
through the last visit and for 30 days after the subject’s last dose.  All SAEs must be followed 
to resolution or, if resolution is unlikely, to stabilization.  Any SAE judged by the 
investigator to be related to the study treatment or any protocol-required procedure should be 
reported to the sponsor regardless of the length of time that has passed since study 
completion.

Page 48 of 75
The detailed contact information for reporting of SAEs is provided in the Investigator Study 
File.
For urgent safety issues, please ensure all appropriate medical care is administered to the 
subject and contact the appropriate study team member listed in the Investigator Study File.
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report.  This includes the investigator’s assessment of causality.
Any follow-up information received on SAEs should be forwarded within 1 business day of 
its receipt.  If the follow-up information changes the investigator’s assessment of causality, 
this should also be noted on the follow-up SAE form.
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested by 
the sponsor.
The investigator must notify his/her IRB/IEC of the occurrence of the SAE, in writing, if 
required by their institution.  A copy of this communication must be forwarded to the sponsor 
to be filed in the sponsor’s Trial Master File.
9.5.4.2
Reporting of Pregnancy and Exposure to Study Drug through Breastfeeding
Any pregnancy in which the estimated date of conception is either before the last visit or 
within 30 days of last study treatment or any exposure to study drug through breastfeeding 
during study treatment or within 30 days of last study treatment must be reported.
If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, this 
should be reported regardless of the length of time that has passed since the exposure to study 
treatment.
A congenital anomaly, death during perinatal period, an induced abortion, or a spontaneous 
abortion are considered to be an SAE and should be reported in the same time frame and in 
the same format as all other SAEs (see Section 9.5.4.1).
Pregnancies or exposure to study drug through breastfeeding must be reported by fax or 
email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy.  The contact information for the reporting of pregnancies 
and exposure to study drug through breastfeeding is provided in the Investigator Study File.  
The Pregnancy Report Form must be used for reporting.  All pregnancies must be followed to 
outcome.  The outcome of the pregnancy must be reported as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the outcome.
A subject who becomes pregnant must be withdrawn from the study.

Reporting of Events Association with Special Situations
9.5.4.3.1
REPORTING OF ADVERSE EVENTS ASSOCIATED WITH STUDY DRUG OVERDOSE,
MISUSE, ABUSE, OR MEDICATION ERROR
Adverse events associated with study drug overdose, misuse, abuse, and medication error 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication error are defined as follows: 
Overdose
Accidental or intentional use of the study drug in an amount higher
than the protocol-defined dose
Misuse
Intentional and inappropriate use of study drug not in accordance with 
the protocol or authorized dose, route of administration, or 
indication(s) or use of prescription-only study drug without a 
prescription
Abuse
Sporadic or persistent intentional excessive use of study drug 
accompanied by harmful physical or psychological effects
Medication error
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of the 
healthcare professional, subject, or consumer.  Such events may be 
related to professional practice, healthcare products, occupational 
exposure, procedures, or
systems,
including prescribing,
order 
communication,
product labeling/packaging/nomenclature,
compounding,
dispensing,
distribution,
administration, education,
monitoring, or use.
All AEs associated with overdose, misuse, abuse, or medication error should be captured on 
the Adverse Event CRF and also reported using the procedures detailed in Section 9.5.4.1
even if the AEs do not meet serious criteria.  Abuse is always to be captured as an AE.  If the 
AE associated with an overdose, misuse, abuse, or medication error does not meet serious 
criteria, it must still be reported using the SAE form and in an expedited manner but should 
be noted as nonserious on the SAE form and the Adverse Event CRF.
9.5.4.3.2
REPORTING OF STUDY-SPECIFIC EVENTS
Study-specific events (serotonin syndrome, psychosis, suicidal behavior, priapism, new onset 
valvular heart disease, new onset PH, malignant neoplasms [with the exception of basal cell 
and squamous cell carcinomas of the skin], and fibroadenomas of the breast or ductal 
carcinoma in situ) should always be considered as serious important medical events and be 
entered on the Adverse Event CRF and reported using the procedures detailed in Reporting 
of Serious Adverse Events (Section 9.5.4.1), even if the study-specific event does not meet 
other serious criteria.

9.5.4.4
Expedited Reporting
The sponsor must inform investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (ie, within 
specific time frames).  For this reason, it is imperative that sites provide complete SAE 
information in the manner described above.
9.5.4.5
Breaking the Blind
In the case of a medical emergency where the appropriate treatment of the subject requires 
knowledge of the study treatment given, the investigator may break the randomization code 
for an individual subject.  In all such cases, the AE necessitating the emergency blind break 
will be handled as an SAE in accordance with the procedures indicated above.  Any broken 
code will be clearly justified and documented.  The medical monitor must be notified 
immediately of the blind break.
9.5.4.6
Regulatory Reporting of Adverse Events
Adverse events will be reported by the sponsor or a third party acting on behalf of the 
sponsor to regulatory authorities in compliance with local and regional law and established 
guidance.  The format of these reports will be dictated by the local and regional 
requirements.
9.5.5
Completion/Discontinuation of Subjects
The investigator may withdraw the subject from the study at any time for safety or 
administrative reasons.  A subject may elect to discontinue the study at any time for any 
reason.  All subjects will continue in the study until the 52 week evaluation is completed.  
Subjects who discontinue treatment prematurely will be followed up until study completion.  
All subjects who discontinue the study are to complete the study’s early discontinuation 
procedures indicated in the Schedule of Procedures/Assessments (Table 2).
The investigator will promptly explain to the subject involved that the study will be 
discontinued for that subject and provide appropriate medical treatment and other necessary 
measures for the subject.  A subject who has ceased to return for visits will be followed up by 
mail, phone, or other means to gather information such as the reason for failure to return, the 
status of treatment compliance, the presence or absence of AEs, and clinical courses of signs 
and symptoms.
Subjects who discontinue early from the study will be discontinued for 1 of these primary 
reasons: AE(s), lost to follow-up, subject choice, withdrawal of consent, pregnancy, study 
terminated by sponsor, or other.  In addition to the primary reason, the subject may indicate
1 or more of secondary reasons for discontinuation.  Study disposition information will be 
collected on the Subject Disposition CRF.
A subject removed from the study for any reason may not be replaced.

9.5.6
Abuse or Diversion of Study Drug
During the study, the investigator will report any concern about abuse or diversion of study 
drugs by completing the CRF.  The DEA Registrant has the responsibility to comply with 
local, state and Federal laws to notify the Field Division Office of the Drug Enforcement 
Administration of any theft or significant loss of any controlled substances upon discovery of 
such theft or loss.  
9.5.7
Confirmation of Medical Care by Another Physician
The investigator will instruct subjects to inform site personnel when they are planning to 
receive medical care by another physician.  At each visit, the investigator will ask the subject 
whether he/she has received medical care by another physician since the last visit or is 
planning to do so in the future.  When the subject is going to receive medical care by another 
physician, the investigator, with the consent of the subject, will inform the other physician 
that the subject is participating in the clinical study.
9.6
Data Quality Assurance
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines.  Site audits 
will be made periodically by the sponsor’s or the CRO’s qualified compliance auditing team, 
which is an independent function from the study team responsible for conduct of the study.
9.6.1
Data Collection
Data required by the protocol will be collected on the CRFs and entered into a validated data 
management system that is compliant with all regulatory requirements.  As defined by ICH 
guidelines, the CRF is a printed, optical, or electronic document designed to record all of the 
protocol-required information to be reported to the sponsor on each study subject.
Data collection on the CRF must follow the instructions described in the CRF Completion 
Guidelines.  The investigator has ultimate responsibility for the collection and reporting of all 
clinical data entered on the CRF.  The investigator or designee as identified on Form FDA 
1572 must sign the completed CRF to attest to its accuracy, authenticity, and completeness.
Completed, original CRFs are the sole property of Eisai and should not be made available in 
any form to third parties without written permission from Eisai, except for authorized 
representatives of Eisai or appropriate regulatory authorities.
9.6.2
Clinical Data Management
All software applications used in the collection of data will be properly validated following 
standard computer system validation that is compliant with all regulatory requirements.  All 
data, both CRF and external data (eg, laboratory data), will be entered into a clinical system.

Efficacy Analyses
For the primary and secondary endpoints, a 2-sided α=0.05 significance level will be used.
The primary analysis is:

The proportion of subjects achieving ≥5% BMI reduction will be analyzed using 
logistic regression model with treatment and site as factors and baseline BMI as a 
covariate.  Comparison between BELVIQ and placebo will be made at Week 52.  The 
FAS analysis set will be used for this analysis.  Sensitivity analysis will be conducted 
treating subjects with missing BMI data at Week 52, as nonresponders (did not 
achieve ≥5% BMI reduction).
The secondary analyses are:

The proportion of subjects achieving ≥5% BMI reduction will be analyzed using 
logistic regression model with treatment and site as a factors, and baseline BMI as a 
covariate.  Comparison between BELVIQ and placebo will be made at Week 12.  The 
FAS analysis set will be used for this analysis.  Sensitivity 
analysis 
will 
be 
conducted treating subjects with missing BMI data at Week 12, as nonresponders (did 
not achieve ≥5% BMI reduction).

Change and percent change from baseline in BMI will be analyzed using an analysis 
of covariance model with treatment and site as factors and baseline BMI as a 
covariate.  Comparison between BELVIQ and placebo will be made at Week 52 using 
the last observation carried forward (LOCF) approach.  The FAS analysis set will be 
used for this analysis.  Additional sensitivity analyses will be performed using 
model-based imputation methods that will be described separately in the SAP.

Rates of growth in height will be summarized by the height distribution of percent 
change from Baseline to Week 52 by treatment group.  The Safety Analysis Set will 
be used for this analysis.

Tanner Staging (II, III, IV, and V) will be summarized using shift tables from 
Baseline to Week 52 by treatment group.  The Safety Analysis Set will be used for 
this analysis.

Analyses
9.7.1.7.1
PHARMACOKINETIC ANALYSES
Lorcaserin plasma concentration-time data will be subjected to population PK analysis using 
nonlinear mixed effects modeling.  The effect of covariates, such as baseline 
characteristics/demographics, on PK will be explored.  Derived exposure parameters such as 
the maximum observed concentration (Cmax) and the area under the concentration-time curve 
from time zero to 24 hours at steady-state (AUC0-24,ss) will be calculated from the final PK 
model using individual posterior estimates of the PK parameters and from dosing history.  
The PK analysis set will be used for this analysis.
9.7.1.7.2
PHARMACODYNAMIC ANALYSES
Proportion (%) of patients achieving ≥5% and ≥10% BMI reduction, and BMI change from 
baseline will be assessed as the PD analysis.  The PD analysis set will be used for this 
analysis.

Other assessments (ie, BMI change, percentage of BMI change, proportion [%] of patients 
achieving ≥10% BMI reduction, and waist circumference from baseline) will also assessed as 
PD analysis.  The PK/PD analysis set will be used for this analysis.
9.7.1.7.3
PHARMACOKINETIC/PHARMACODYNAMIC ANALYSES
Population PK/PD modeling will be used to explore the relationship between exposure to 
BELVIQ and response, including but not limited to change in BMI from baseline and the 
probability of achieving ≥5% and ≥10% change in BMI from baseline to Week 52.  
Additionally, exposure-safety relationships for select safety parameters may be explored 
graphically.  Any emergent relationship may be modeled as appropriate.  Any parameters 
based on the study data may be considered for exploratory assessment for its relationship to 
PK.
9.7.1.7.4
PHARMACOGENOMIC AND PHARMACOGENETIC ANALYSES
At the time of randomization, when applicable, a blood sample will be taken for potential 
investigation of genetic variability associated with genotypes relating to response to 
BELVIQ, weight loss, susceptibility to diabetes, and their associated risk factors
(Appendix 3).
Data obtained from the PD and PG samples will be used for research. The PD and 
PGsamples will not be used to determine or predict risks for diseases that an individual 
subject does not currently have.  Any sample or derivatives (DNA, RNA, and protein) may 
be stored for up to 15 years to assist in any research scientific questions related to BELVIQ 
and for potential diagnostic development. If the subject reaches 18 years of age prior to the 
date of final sample analyses they will be reconsented. No further analyses will be performed 
on these collected samples from subjects who either do not reconsent after their 18th birthday 
or cannot be reached for re-consenting and the sample will be destroyed
9.7.1.8
Safety Analyses
Evaluations of safety will be performed on the Safety Analysis Set.  The incidence of AEs 
(including changes from baseline in physical examination), suicidal ideation/behavior 
(C-SSRS), neuropsychiatric events, out-of-normal-range laboratory safety test variables, 
along with change from baseline in laboratory safety test variables, and vital sign 
measurements at end of treatment will be summarized by treatment group using descriptive 
statistics.  Study Day 1 for all safety analyses will be defined as the date of the first dose of 
study drug.
9.7.1.8.1
EXTENT OF EXPOSURE
Subjects will receive BELVIQ 20 mg or placebo QD for up to 52 weeks. 
9.7.1.8.2
ADVERSE EVENTS
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities

(MedDRA).  Adverse events will be coded to the MedDRA (Version 18.0 or higher) lower 
level term closest to the verbatim term.  The linked MedDRA PT and primary system organ 
class (SOC) are also captured in the database.
A treatment-emergent adverse event (TEAE) is defined as an AE that emerges during 
treatment, having been absent at pretreatment (Baseline) or 
•
Reemerges during treatment, having been present at pretreatment (Baseline) but stopped 
before treatment, or 
•
Worsens in severity during treatment relative to the pretreatment state, when the AE is 
continuous.
Only those AEs that were treatment emergent will be included in summary tables.  All AEs, 
treatment emergent or otherwise, will be presented in subject data listings.
The TEAEs will be summarized by treatment group.  The incidence of TEAEs will be 
reported as the number (percentage) of subjects with TEAEs by SOC and PT.  A subject will 
be counted only once within a SOC and PT, even if the subject experienced more than
1 TEAE within a specific SOC and PT.  The number (percentage) of subjects with TEAEs 
will also be summarized by maximum severity (mild, moderate, or severe).
The number (percentage) of subjects with treatment-related TEAEs will be summarized by 
SOC and PT.  Treatment-related TEAEs include those events considered by the investigator 
to be related to study treatment.  The number (percentage) of subjects with treatment-related 
TEAEs will also be summarized by maximum severity (mild, moderate, or severe).
The number (percentage) of subjects with TEAEs will also be summarized by relationship to 
study drug (Yes [related] and No [not related]).
Adverse events will be summarized using the Safety Analysis Set.  The number of AEs and 
number and incidence (%) of subjects with AEs will be summarized by treatment group and 
overall.  To obtain the incidence (%), the number of subjects with at least 1 event and the 
percentage of subjects with AEs by SOC and by PT will be calculated.  Incidence (%) by 
causal relationship with study drug and by severity will also be calculated.  For clinically 
significant events, time of onset, and recovery will be reported.
The number (percentage) of subjects with TEAEs leading to death will be summarized by 
MedDRA SOC and PT for each treatment group.  A subject data listing of all AEs leading to 
death will be provided.
The number (percentage) of subjects with treatment-emergent serious adverse events will be 
summarized by MedDRA SOC and PT for each treatment group.  A subject data listing of all 
SAEs will be provided.
The number (percentage) of subjects with TEAEs leading to discontinuation from study drug 
will be summarized by MedDRA SOC and PT for each treatment group. A subject data 
listing of all AEs leading to discontinuation from study drug will be provided.

9.7.1.8.3
LABORATORY VALUES
Laboratory results will be summarized using Système International (SI) units, as appropriate.  
For all quantitative parameters listed in Section 9.5.1.5.3, the actual value and the change 
from baseline to each postbaseline visit and to the end of treatment (defined as the last 
on-treatment value) will be summarized by visit and treatment group using descriptive 
statistics.  Qualitative parameters listed in Section 9.5.1.5.3 will be summarized using 
frequencies (number and percentage of subjects), and changes from baseline to each 
postbaseline visit and to end of treatment will be reported using shift tables.  Percentages will 
be based on the number of subjects with both nonmissing baseline and relevant postbaseline 
results.
Laboratory test results will be assigned a low/normal/high (LNH) classification according to 
whether the value was below (L), within (N), or above (H) the laboratory parameter’s 
reference range.  Within-treatment comparisons for each laboratory parameter will be based 
on 3-by-3 tables (shift tables) that compare the baseline LNH classification to the LNH 
classification at each postbaseline visit and at the end of treatment.  Similar shift tables will 
also compare the baseline LNH classification to the LNH classification for the highest and 
lowest value during the treatment period.
Appendix 1
presents the criteria that will be used to identify subjects with 
treatment-emergent markedly abnormal laboratory values (TEMAV).  Except for phosphate, 
a TEMAV is defined as a postbaseline value with an increase from baseline to a grade of 2 or 
higher.  For phosphate, a TEMAV was defined as a postbaseline value with an increase from 
baseline to a grade of 3 or higher.  When displaying the incidence of TEMAVs, each subject 
may be counted once in the laboratory parameter high and in the laboratory parameter low 
categories, as applicable.
9.7.1.8.4
VITAL SIGNS
Descriptive statistics for vital signs parameters (ie, systolic and diastolic BP, pulse, 
respiratory rate, temperature, weight) and changes from baseline will be presented by day 
and time after dosing.
9.7.1.8.5
ELECTROCARDIOGRAMS
Descriptive statistics for ECG parameters and changes from baseline will be presented by 
treatment group. 
Shift tables will present changes from baseline in ECG interpretation (categorized as normal; 
abnormal, not clinically significant; and abnormal, clinically significant) to end of treatment. 
In addition, the number (percentage) of subjects with at least 1 postbaseline abnormal ECG 
result in QTc Bazett and QTc Fridericia during the treatment period will be summarized.  
Clinically abnormal ECG results in QTc Bazett and QTc Fridericia will be categorized as

Determination of Sample Size
A sample size of 360 subjects in a 1:1 ratio (n=180 in the BELVIQ 20 mg QD treatment 
group: n=180 in the placebo group) will have 90% power to detect a 20% difference in 
proportions of subjects with at least 5% reduction in BMI, assuming the placebo response is 
20%, using a 2-sided test and α=0.05, assuming a 35% dropout rate.  The assumption is 
based on lorcaserin adult Phase 3 and adolescent studies with orlistat and sibutramine 
(Chanoine JP, 2005; Berkowitz. R, 2006).

11 PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE 
PROCEDURES)
11.1
Changes to the Protocol
Any change to the protocol requires a written protocol amendment or administrative change 
that must be approved by the sponsor before implementation.  Amendments specifically 
affecting the safety of subjects, the scope of the investigation, or the scientific quality of the 
study require submission to health or regulatory authorities as well as additional approval by 
the applicable IRBs/IECs.  These requirements should in no way prevent any immediate 
action from being taken by the investigator, or by the sponsor, in the interest of preserving 
the safety of all subjects included in the study.  If the investigator determines that an 
immediate change to or deviation from the protocol is necessary for safety reasons to 
eliminate an immediate hazard to the subjects, the sponsor’s medical monitor and the 
IRB/IEC for the site must be notified immediately.  The sponsor must notify the health or 
regulatory authority as required per local regulations.
Protocol amendments that affect only administrative aspects of the study may not require 
submission to health or regulatory authority or the IRB/IEC, but the health or regulatory 
authority and IRB/IEC should be kept informed of such changes as required by local 
regulations.  In these cases, the sponsor may be required to send a letter to the IRB/IEC and 
the Competent Authorities detailing such changes.
11.2
Adherence to the Protocol
The investigator will conduct the study in strict accordance with the protocol (refer to ICH 
E6, Section 4.5).
11.3
Monitoring Procedures
The sponsor’s/CRO’s CRA will maintain contact with the investigator and designated staff 
by telephone, letter, or email between study visits.  Monitoring visits to each site will be 
conducted by the assigned CRA as described in the monitoring plan.  The investigator will 
allow the CRA to inspect the clinical, laboratory, and pharmacy facilities to assure 
compliance with GCP and local regulatory requirements.  The CRFs and subject’s 
corresponding original medical records (source documents) are to be fully available for 
review by the sponsor’s representatives at regular intervals.  These reviews verify adherence 
to study protocol and data accuracy in accordance with local regulations.  All records at the 
site are subject to inspection by the local auditing agency and IRB/IEC review.

In accordance with ICH E6, Section 1.52, source documents include, but are not limited to 
the following:
•
Clinic, office, or hospital charts
•
Copies or transcribed health care provider notes which have been certified for accuracy 
after production
•
Recorded data from automated instruments such as IxRS, x-rays, and other imaging 
reports, (eg, sonograms, computerized tomography scans, magnetic resonance images, 
radioactive images, ECGs, rhythm strips, EEGs, polysomnographs, pulmonary function 
tests) regardless of how these images are stored, including microfiche and photographic 
negatives
•
Pain, quality of life, or medical history questionnaires completed by subjects
•
Records of telephone contacts
•
Diaries or evaluation checklists
•
Drug distribution and accountability logs maintained in pharmacies or by research

documentation and urine dip-sticks)
•
Correspondence regarding a study subject’s treatment between physicians or memoranda 
sent to the IRBs/IECs
•
CRF components (eg, questionnaires) that are completed directly by subjects and serve as 
their own source
11.4
Recording of Data
A CRF is required and must be completed for each subject by qualified and authorized 
personnel.  All data on the CRF must reflect the corresponding source document, except 
when a section of the CRF itself is used as source document.  Any correction to entries made 
on the CRF must be documented in a valid audit trail where the correction is dated, the 
individual making the correct is identified, the reason for the change is stated, and the 
original data are not obscured.  Only data required by the protocol for the purposes of the 
study should be collected.
The investigator must sign each CRF.  The investigator will report the CRFs to the sponsor 
and retain a copy of the CRFs.
11.5
Identification of Source Data
All data to be recorded on the CRF must reflect the corresponding source documents.

11.6
Retention of Records
The circumstances of completion or termination of the study notwithstanding, the 
investigator is responsible for retaining all study documents, including but not limited to the 
protocol, copies of CRFs, the Investigator's Brochure, and regulatory agency registration 
documents (eg, Form FDA 1572 ICFs, and IRB/IEC correspondence).  In addition, the 
sponsor will send a list of treatment codes by study subject to the investigator after the 
clinical database for this study has been locked.  The site should plan to retain study 
documents, as directed by the sponsor, for at least 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region or at least 3 years have elapsed since the formal 
discontinuation of clinical development of the investigational product.
It is requested that at the completion of the required retention period, or should the 
investigator retire or relocate, the investigator contact the sponsor, allowing the sponsor the 
option of permanently retaining the study records.
11.7
Auditing Procedures and Inspection
In addition to the routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of ICH GCP and all applicable local 
regulations.  If a government regulatory authority requests an inspection during the study or 
after its completion, the investigator must inform the sponsor immediately.
11.8
Handling of Study Drug
All study drugs will be supplied to the principal investigator (or a designated pharmacist) by 
the sponsor.  Drug supplies must be kept in an appropriate secure area (eg, locked cabinet) 
and stored according to the conditions specified on the drug labels.  Investigational product 
will be stored in accordance with the DEA Regulations for Scheduled III - V Drugs and 
labeled storage conditions.  The investigator (or a designated pharmacist) must maintain an 
accurate record of the shipment and dispensing of the study drug in a drug accountability 
ledger, a copy of which must be given to the sponsor at the end of the study.  An accurate 
record of the date and amount of study drug dispensed to each subject must be available for 
inspection at any time.  The CRA will visit the site and review these documents along with 
all other study conduct documents at appropriate intervals once study drug has been received 
by the site.
All drug supplies are to be used only for this study and not for any other purpose.  The 
investigator (or site personnel) must not destroy any drug labels or any partly used or unused 
drug supply before approval to do so by the sponsor.  At the conclusion of the study and as 
appropriate during the study, the investigator (or a designated pharmacist) will return all used 
and unused drug containers, drug labels, and a copy of the completed drug disposition form 
to the sponsor’s CRA.

Appendix 2
Family-Based Lifestyle Program
Program Overview
All subjects and their caregivers (participating parent/guardian) in Study 403 will participate 
in a standardized weight management program for adolescents consisting of multicomponent 
behavior therapy.  The therapy will focus on healthy eating, physical activity, and lifestyle
changes that will facilitate weight loss and weight-loss maintenance. The role of the 
caregivers is to support their adolescents’ lifestyle changes and their taking of study 
medication.
The objectives of this program are as follows:

Develop a weight management program for all BELVIQ study participants and their 
caregivers (caregivers are instructed in methods to support their adolescents’ progress 
but caregivers are themselves not instructed to lose weight or take medication)

Standardize the weight management program across all study sites

Maximize participant retention

Promote participant’s adherence to both taking study medication and following the 
lifestyle program

Appendix 3
Pharmacodynamic, Pharmacogenomic, and Other 
Biomarker Research
Subjects enrolled in this clinical study will have biologic samples collected for 
pharmacodynamic (PD), pharmacogenomic (PG), and other biomarker analysis.  These 
samples may be used for discovery or validation to identify biomarkers that may be used for 
exploratory evaluation of response and/or safety-related outcomes as well as for use in 
diagnostic development.
The PG samples may be used to identify genetic factors that may influence a subject’s 
exposure to the study drug, as well as genetic factors that may have an effect on clinical 
response or potential adverse events related to study treatment, and to explore the role of 
genetic variability in response.  Samples may be analyzed to determine a subject’s genotypes 
or sequence for a number of genes or non-coding regulatory regions.  The research may 
include the investigation of polymorphisms in genes that are likely to influence the study 
drug pharmacokinetics or therapeutic response.
Collection of the PD, PG, and other biomarker samples will be bound by the sample 
principles and processes outlined in the main study protocol.  Sample collection for PD, PG, 
and other biomarker analysis is required as per the study protocol unless the collection and 
use of the samples is prohibited by specific country laws.
Sample Collection and Handling
The samples will be collected according to the study flow chart.  If, for operational or 
medical reasons, the genomic DNA blood sample cannot be obtained at the prespecified visit, 
the sample can be taken at any study center visit at the discretion of the investigator and site 
staff.
Security of the Samples, Use of the Samples, Retention of the Samples
Sample processing, for example DNA and/or RNA extraction, genotyping, sequencing, or 
other analysis will be performed by a laboratory under the direction of the sponsor.  
Processing, analysis, and storage will be performed at a secure laboratory facility to protect 
the validity of the data and maintain subject privacy.
Samples will only be used for the purposes described in this protocol.  Laboratories 
contracted to perform the analysis on behalf of the sponsor will not retain rights to the 
samples beyond those necessary to perform the specified analysis and will not transfer or sell 
those samples.  The sponsor will not sell the samples to a third party.
Samples will be stored for up to 15 years after the completion of the study (defined as 
submission of the clinical study report to the appropriate regulatory agencies).  At the end of 
the storage period, samples will be destroyed.  Samples may be stored longer if a health 
authority (or medicinal product approval agency) has active questions about the study.  In 
this special circumstance, the samples will be stored until the questions have been adequately 
addressed.

It is possible that future research and technological advances may identify genomic variants 
of interest, or allow alternative types of genomic analysis not foreseen at this time.  Because 
it is not possible to prospectively define every avenue of future testing, all samples collected 
will be single or double coded (according to the ICH E15 guidelines) in order to maintain 
subject privacy. 
Right to Withdraw
If, during the time the samples are stored, a participant would like to withdraw his/her 
consent for participation in this research, Eisai will destroy the samples.  Information from 
any assays that have already been completed at the time of withdrawal of consent will 
continue to be used as necessary to protect the integrity of the research project.
Subject Privacy and Return of Data
No subject-identifying information (eg, initials, date of birth, government identifying 
number) will be associated with the sample.  All PD and other biomarker samples will be 
single coded.  Genomic DNA samples used to explore the effects on PK, treatment response, 
and safety will be single coded.  Genomic DNA samples that will be stored for long-term use 
(defined as 15 years after the completion of the study) will be double coded.  Double coding 
involves removing the initial code (subject ID) and replacing with another code such that the 
subject can be re-identified by use of 2 code keys.  The code keys are usually held by 
different parties.  The key linking the sample ID to the subject number will be maintained 
separately from the sample.  At this point, the samples will be double-coded, the first code 
being the subject number.  Laboratory personnel performing genetic analysis will not have 
access to the “key.”  Clinical data collected as part of the clinical trial will be cleaned of 
subject identifying information and linked by use of the sample ID “key.”
The sponsor will take steps to ensure that data are protected accordingly and confidentiality 
is maintained as far as possible.  Data from subjects enrolled in this study may be analyzed 
worldwide, regardless of location of collection.
The sponsor and its representatives and agents may share coded data with persons and 
organizations involved in the conduct or oversight of this research.  These include:
•
Clinical research organizations retained by the sponsor 
•
Independent ethics committees or institutional review boards that have responsibility for 
this research study 
•
National regulatory authorities or equivalent government agencies
At the end of the analysis, results may be presented in a final report which can include part or 
all of the coded data, in listing or summary format.  Other publication (eg, in peer-reviewed 
scientific journals) or public presentation of the study results will only include summaries of 
the population in the study, and no identified individual results will be disclosed.

Given the research nature of the PD, PG, and other biomarker analysis, it will not be possible 
to return individual data to subjects.  The results that may be generated are not currently 
anticipated to have clinical relevance to the patients or their family members.  Therefore, 
these results will not be disclosed to the patients or their physicians.
If at any time, PD, PG, and/or other biomarker results are obtained that may have clinical 
relevance, IRB review and approval will be sought to determine the most appropriate manner 
of disclosure and to determine whether or not validation in a Clinical Laboratory 
Improvement Amendments (CLIA)-certified setting will be required.  Sharing of research 
data with individual patients should only occur when data have been validated by multiple 
studies and testing has been done in CLIA-approved laboratories.
