Efficacy:
(revised per Amendment 02)

To demonstrate that, in obese and overweight subjects with CV disease and/or multiple CV risk factors,
lorcaserin HCl 10 mg BID reduces the incidence of MACE+ (MACE or hospitalization for unstable angina 
or heart failure (HF), or any coronary revascularization) compared to placebo
Secondary Objectives
Key Secondary Objective

To confirm that, in subjects with prediabetes at Baseline based on the 2013 ADA guideline, lorcaserin HCl 
10 mg BID reduces the incidence of conversion to type 2 diabetes mellitus (T2DM) compared to placebo

impact of different metabolic and CV pathologic processes on weight loss, the response to lorcaserin HCl, 
susceptibility to diabetes, and the risk of developing CV and other end-organ disease and their associated 
risk factors (for participating countries/sites where ethics and regulatory approval is obtained)

To explore the effects of long-term treatment with lorcaserin HCl (10 mg BID) on improvement of obesity 
related complications, as defined by the 2014 Advanced Framework for a New Diagnosis of Obesity as a 
Chronic Disease (American Association of Clinical Endocrinologists [AACE] and American College of 
Endocrinology [ACE]) (eg, pre diabetes, metabolic syndrome, hypertriglyceridemia/dyslipidemia, and 
potentially others) (revised per Amendment 01)

To demonstrate that lorcaserin HCl 10 mg BID improves glycemic control, and/or reduction in OAD 
medications for the subjects treated with OADs, compared to placebo at 6 months in the following 
subpopulations of patients with T2DM:
o
Subjects with T2DM with an HbA1c>7% at Baseline
o
Subjects with T2DM who have not been treated with antidiabetic agents at Baseline
o
Subjects with T2DM who are on Monotherapy with an oral antidiabetic agent at Baseline
o
Subjects with early T2DM (duration of diagnosis of diabetes is less than 5 years) at Baseline 
Study Design
This will be a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in overweight and 
obese subjects with CV disease and/or multiple CV risk factors.  Approximately 12,000 subjects will be randomized 
to 2 treatment groups in a ratio of 1:1, stratified by the presence of established CV disease (~80%) or CV risk factors 
without established CV disease (~20%). The 80% of subjects in the established CV disease strata will consist of a 
group with T2DM (approximately 30% of the total number of subjects in the study) and a group without T2DM 
(approximately 50% of the total number of subjects in the study).  The 20% of subjects in the strata with CV risk 
factors but without established CV disease will all have T2DM, as well as additional risk factors. Therefore,
approximately 50% of the total number of subjects in the study will have T2DM.
Subjects will receive lorcaserin HCl 10 mg BID or placebo BID for approximately 5 years.  Throughout the duration 
of the study, subjects will be provided with instructions regarding a reduced-calorie diet and increased physical 
activity program. Echocardiography will be performed on a subset of approximately 3600 subjects at Baseline and 
at 6, 12, 18, 24 months, and yearly thereafter.  Acquisition of new ECHO data in all subjects will cease when at least
1000 subjects have completed the Month 36 echocardiographic assessment.  (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 
will consist of 2 periods:  Treatment and Follow-up.  The Treatment Period will last for approximately 5 years with 
approximately 18 visits.  The first dose should be taken at Randomization Visit 2.  (revised per Amendment 01)  The 
Follow-up Period extends from the end of treatment (EOT) visit to the EOS visit. Sponsor Notification of Study 
Completion will occur once 1401 MACE+ events, 460 MACE events, and a median treatment duration of 2.5 years
have accrued.  (revised per Amendment 02)  This is expected to occur on or before October 2018.  Following this 
announcement (“Sponsor Notification of Study Completion”), sites will be instructed to bring subjects who remain 
on treatment for an EOT visit.  An EOS visit will occur approximately 30 days later for subjects on treatment at 
Sponsor Notification of Study Completion.  (revised per Amendment 01)  Subjects who are still being followed in 
the study but have already discontinued study medication ≥30 days before will return for an EOS visit.  Subjects 
who are still being followed in the study but who discontinued study medication within the last 30 days will return 
for an EOS visit approximately 30 days after their last dose of study medication.
During this study, the endpoints of MACE and MACE+ will need to be reported in an expedited fashion by 
investigators to the Clinical Endpoint Committee (CEC) and to the Eisai Product Safety Department. 
MACE/MACE+ events will be recorded on the adverse event (AE) case report form, but these events will not be 
considered as AEs, nor will they be recorded as serious adverse events (SAEs) in the clinical trial database or be 
required to be reported to regulatory authorities in an expedited timeframe, with the exception of MACE or MACE+

events that are considered by the investigator to be at least possibly related to the study drug (ie, where there is 
evidence to suggest a causal relationship).  (revised per Amendment 01)
All subjects will continue in the study until study completion rather than for a prespecified number of visits. 
Subjects will remain in the study even after their first nonfatal MACE event. Subjects who discontinue treatment 
prematurely will be followed up for safety until study completion (ie, they will attend the remaining study visits for 
safety assessments).

In order to reduce intra- and inter-site variability, the CEC will centrally review each potential MACE and 
MACE+ event to ensure standardization of data collection and interpretation of such events reported 
throughout the study.  The CEC will determine whether each potential event meets criteria for MACE or 
MACE+.  The CEC will remain blinded to treatment allocation and its activities and the criteria for 
classification of MACE/MACE+ events will be documented in the CEC Charter.
When 460 adjudicated MACE events have occurred, an interim analysis will be conducted on MACE events. It will

1 postbaseline assessment of at least 1 PD parameter.
Primary Safety and Efficacy and Key Secondary Analyses (revised per Amendment 02)
The primary endpoints, MACE, and MACE+, will be analyzed using a Cox proportional hazards model that 
includes factors for treatment and stratification variable (presence of established CV disease or CV risk factors 
without established CV disease).  (revised per Amendment 02)  For secondary and exploratory endpoints a 2-sided α 
= 0.05 significance level will be used.  The MACE analysis (“interim” analysis) will be conducted when

460 adjudicated MACE events have been recorded; the other analyses will be conducted when 1401 adjudicated 
MACE+ events have been recorded, and the study has completed.  (revised per Amendment 02)
Sequential Gatekeeping Testing Procedure
The following closed sequential gatekeeping testing procedure (SGTP) will be used to control the family-wise error 
rate (FWER) at α = 0.05 (2-sided) in testing the 2 primary endpoints (MACE and MACE+) and 1 key secondary 
endpoint, conversion to T2DM.  (revised per Amendment 02)
Let H01 be the gatekeeping null hypothesis for noninferiority testing of the MACE endpoint using a noninferiority 
margin of 1.4.
Let H02 and H03 be the null hypotheses for superiority testing: MACE+ and conversion to T2DM, respectively.  
(revised per Amendment 02)
The SGTP testing hierarchy is presented below.  (revised per Amendment 02)

STEP1:  At the interim analysis, test the noninferiority hypothesis for MACE, H01 (α = 0.025, 1-sided).  If 
H01 is rejected, then proceed to STEP2, otherwise stop testing and the trial will be stopped.

STEP2:  At study completion the hypothesis H02 (α = 0.05, 2-sided) is tested first. If the hypothesis is 
rejected, then proceed to test H03 (α = 0.05, 2-sided). If H02 is not rejected, then testing stops at this point.   
The flowchart below presents the SGTP:
Primary Endpoint Analyses

Time to MACE:  The estimate of the hazard ratio of lorcaserin HCl to placebo and the corresponding 
1-sided 97.5% confidence interval (CI) will be calculated.  Noninferiority of lorcaserin HCl to placebo will

Interim Analysis
There will be 1 interim analysis; when 460 adjudicated MACE events have occurred, the primary analysis for 
MACE will be conducted.  This will be the analysis to rule out a hazard ratio of 1.4.  The study will continue to 
accrue events until the required number of MACE+ have occurred.  (revised per Amendment 02)  Sensitivity 
analysis for MACE endpoint will be performed after all the MACE+ events have accrued.  (revised per 
Amendment 02)  At the time of MACE+ analyses, there will be approximately 600 MACE events.
The interim analysis for MACE endpoint will be performed by an independent statistician and governed by an 
independent DMC and is anticipated to occur on or before (approximately) Jul 2017.  (revised per Amendment 02)  
The interim analysis will be conducted to establish whether the MACE primary objective has been achieved.  To 
maintain the integrity and  credibility of the trial, procedures will be implemented to ensure the DMC and 
independent statistician have sole access to evolving information from the clinical trial regarding comparative 
efficacy and safety data aggregated by treatment group.  Full details of the DMC procedures including primary 
responsibilities of the DMC, its relationship with other trial components, its membership, and the purpose and 
timing of its meetings will be documented in the DMC Charter.  These details will also include procedures to ensure 
confidentiality and proper communication (as outlined in the Study Integrity Charter), the safety and statistical 
monitoring guidelines to be implemented by the DMC, and an outline of the content of the closed reports and open 
reports that will be provided to the DMC.  (revised per Amendment 02)
At the interim analysis for MACE, the estimate of the hazard ratio of lorcaserin HCl to placebo and the 
corresponding 97.5% CI will be calculated.  Noninferiority between lorcaserin HCl and placebo will be declared if 
the upper limit of the 97.5% CI is less than or equal to the noninferiority margin of 1.4.  If the upper limit of the 
97.5% CI is greater than 1.4, then lorcaserin HCl will be declared as not noninferior to placebo and the trial will 
stop.
If noninferiority between lorcaserin HCl and placebo is confirmed when 460 adjudicated MACE events are observed 
at approximately 43 months from the start of the study, then the study will be continued to observe 1401 MACE+ 
events at approximately 54 months from the start of the study, and a minimum median treatment duration of 
2.5 years have accrued.  (revised per Amendment 02)  The events for MACE+ and T2DM will be tested according 
to the SGTP described previously, upon study completion.  (revised per Amendment 02)
Sample Size Rationale
A sample size of 12,000 subjects should provide the required power for the primary endpoints and key secondary 
endpoint as follows:
Primary Endpoints (revised per Amendment 02)

For 460 MACE events to have occurred by approximately 43 months from start of the study, providing 
95% power to exclude a noninferiority margin of 1.4, assuming an annual background rate of 1.5%, 
15-month accrual period, 5% annual drop-out rate, α = 0.025, and a 1-sided test

For 1401 MACE+ events to have occurred by approximately 54 months from the start of the study,

INTRODUCTION
Obesity has reached global epidemic proportions as the prevalence has nearly doubled from 
20 years ago. According to the World Health Organization (WHO), more than 1 billion adults 
worldwide are overweight, and at least 300 million are obese.1 In the US, more than one-third of 
adults (35.7%) and almost 17% of children and adolescents are obese.2 Obesity is a major risk 
factor for life threatening diseases such as type 2 diabetes mellitus (T2DM), heart attack, stroke, 
and some forms of cancer.  For example, the age-adjusted relative risk of developing T2DM is 
approximately 10-fold higher for men with a body mass index (BMI) of 30 kg/m2 relative to men 
with a BMI <23 kg/m2 and the risk is even higher for women, where a BMI of 30 kg/m2 is 
associated with an approximately 30-fold higher risk.3,4 Obesity is a major cause of morbidity 
and mortality, and it is estimated that there are 300,000 obesity-related deaths annually in the US 
alone.5
It is well established that modest weight reductions of 5% to 10% of body weight can decrease 
blood pressure (BP) and total blood cholesterol, improve glucose tolerance in diabetic patients 
and those with impaired glucose tolerance prone to develop diabetes, and reduce the severity of
obstructive sleep apnea. Given the rise in the prevalence of obesity, even modest weight loss can 
be important to the overall health. 
Current approaches to weight management include life style modification, pharmacotherapy and 
invasive bariatric procedures.  Lifestyle modification involving a combination of diet, exercise, 
and behavioral change is the preferred and essential strategy for weight management in obese 
and overweight individuals. Although behavior 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 behavioral changes 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 beneficial effects 
of many available agents are in part offset by side effects that can include increased BP (agents 
with sympathomimetic activity) or unpleasant gastrointestinal events (orlistat). 
Over the past 2 decades there have been numerous attempts to develop safe and effective drugs 
for weight management.  However, most have failed to gain approval or have been withdrawn 
from the market due to serious safety concerns.  Furthermore, no agent has demonstrated long-
term cardiovascular (CV) benefit.
APD356/BELVIQ® (lorcaserin hydrochloride) 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 greater than or equal to 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.
The Phase 3 clinical evaluation of lorcaserin HCl in clinical trials of more than 7700 patients, 
including 604 patients with 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 lorcaserin HCl 10 mg twice daily (BID) dose met prespecified 
primary endpoints for weight loss:

A significantly greater proportion of patients taking lorcaserin HCl lost ≥5% of baseline 
body weight at 1 year as compared to placebo

The mean weight loss at 1 year in patients taking lorcaserin HCl was significantly greater 
than that in patients taking placebo

A significantly greater proportion of patients taking lorcaserin HCl lost ≥10% of baseline 
body weight at 1 year as compared to placebo

The weight loss efficacy was supported in each trial by favorable trends in multiple other 
measures of CV risk, glycemic control and quality of life.  

Glycosylated hemoglobin (HbA1c) was statistically significantly reduced by 0.5% among 
patients with T2DM compared to placebo.
Based on the results of the Phase 3 data, BELVIQ (lorcaserin HCl) has a favorable benefit-risk 
profile as a pharmacological agent for weight management in obese and overweight patients.
The overall efficacy and safety profile of BELVIQ (lorcaserin HCl) makes it an ideal 
pharmacological agent for weight management, potentially leading to a long term CV benefit.
7.1
STUDY RATIONALE
The sample size and duration of this cardiovascular outcomes trial (CVOT) allows us to design 
the study not only to meet FDA’s requirements but, in addition, to evaluate additional 
indications. 
In the previously pooled Phase 3 dataset from Studies APD356-009 and 
APD356-011 (the 2 nondiabetic studies, total n=7190), BELVIQ (lorcaserin HCl) significantly 
improved BMI, waist circumference, serum lipid profiles, BP, glycemic parameters, and other 
markers of CV risk (high sensitivity C-reactive protein [hsCRP], fibrinogen).  These findings 
suggest that rather than there being a risk of an increase in CV events, it is possible that through 
improvement in risk parameters, BELVIQ (lorcaserin HCl) may have a favorable impact on CV 
risk, and therefore a reduction in major adverse cardiovascular events (MACE)+ is included in 
the study as a coprimary endpoint.
By selecting a large diabetes subpopulation within a population of otherwise high CV risk 
subjects, this study will be able to evaluate the safety of BELVIQ (lorcaserin HCl) in patients 
with type 2 diabetes and additional CV risk, contributing to satisfying the requirement of 
establishing CV safety for a potential future diabetes indication.

In a historic clinical trial, Diabetes Prevention Program (DPP)6, a 5% weight loss translated to a 
significant decrease in the incidence of new diabetes. In the pooled Phase 3 dataset from studies 
APD356-009 and APD356-011 (the 2 nondiabetic studies, total n=7190), weight loss was 
significantly greater than 5% in the BELVIQ-treated group.  In the prediabetes subpopulation 
(25% of the total combined population) of the aforementioned studies, BELVIQ (lorcaserin HCl) 
statistically significantly decreased the incidence of newly developed T2DM (HbA1c ≥6.5). In 
addition, the 2 studies demonstrated that BELVIQ (lorcaserin HCl) improves fasting glucose, 
HbA1c, and insulin resistance in these insulin-resistant nondiabetic populations. In the current 
proposed study, there is a significant prediabetic obese population (approximately 25% to 35% 
of the total population), which allows confirmation of the Phase 3 trial findings. (revised per 
Amendment 01) 
In addition, the large sample size and long follow-up duration in this 
subpopulation provides the opportunity to demonstrate BELVIQ (lorcaserin HCl) not only can 
delay conversion to T2DM, but also delay the progression of renal impairment due to diabetes, 
which will confirm that the effect is indeed due to glycemic benefit, not due to improvement of 
other risk factors.
In the APD356-010 trial (n=508), BELVIQ (lorcaserin HCl) significant improved glycemic
control across all BMI categories on top of standard diabetes treatment. The proposed substudy 
in T2DM subjects at Baseline treated with oral anti-diabetics (OADs) allow confirmation of the 
Phase 3 trial finding that BELVIQ (lorcaserin HCl) improves glycemic control in this diabetic 
subpopulation. The large sample size (the diabetes population at Baseline is about 50% of the 
total population) allows further demonstration of the independent effect of glycemic benefit from 
other improvement in weight reduction-related risk factors.

INVESTIGATIONAL PLAN
9.1
OVERALL STUDY DESIGN AND PLAN
This will be a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in 
overweight and obese subjects with CV disease and/or multiple CV risk factors.  Approximately 
12,000 subjects will be randomized to 2 treatment groups in a ratio of 1:1, stratified by the 
presence of established CV disease (~80%) or CV risk factors without established CV disease 
(~20%). The 80% of subjects in the established CV disease strata will consist of a group with 
T2DM (approximately 30% of the total number of subjects in the study) and a group without 
T2DM (approximately 50% of the total number of subjects in the study).  The 20% of subjects in 
the strata with CV risk factors but without established CV disease will all have T2DM, as well as 
additional risk factors.   Therefore, approximately 50% of the total number of subjects in the 
study will have T2DM (Table 1).

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 will consist of 2 periods:  Treatment and Follow-up.  The 
Treatment Period will last for approximately 5 years with approximately 18 visits.  The first dose 
should be taken at Visit 2. (revised per Amendment 01)  The Follow-up Period extends from the 
end of treatment (EOT) visit to the EOS visit.  Sponsor Notification of Study Completion will 
occur once 1401 MACE+ events, 460 MACE events, and median treatment duration of 2.5 years
have accrued.
This is expected to occur on or before October 2018.  Following this 
announcement (“Sponsor Notification of Study Completion”), sites will be instructed to bring 
subjects who remain on treatment for an EOT visit.  An EOS visit will occur approximately 
30 days later for subjects on treatment at Sponsor Notification of Study Completion. (revised per 
Amendment 01)  Subjects who are still being followed in the study but have already 
discontinued study medication ≥30 days before will return for an EOS visit.  Subjects who are 
still being followed in the study but who discontinued study medication within the last 30 days 
will return for an EOS visit approximately 30 days after their last dose of study medication.  
Subjects will receive lorcaserin HCl 10 mg BID or placebo BID for approximately 5 years.  
Throughout the duration of the study, subjects will be provided with instructions regarding a 
reduced-calorie

at least 1000 subjects have completed the Month 36 echocardiographic assessment.  (revised per 
Amendment 02)
All subjects will continue in the study until study completion, rather than for a prespecified 
number of visits. Subjects who prematurely discontinue study drug will continue in the study for 
all subsequent study visits until study completion and are to complete visit procedures as 
indicated in Table 4.  It is preferred that these visits are in person.  However, if the subject is 
unable to attend a visit in person, a telephone visit may be performed.  The outcome of the 
telephone visit must be clearly documented in the source record.  At a minimum, the site should 
attempt to have the subject return for an in-person visit at least once per year.  The study will 
terminate when 1401 MACE+ events have occurred and when there has been a median treatment 
duration of 2.5 years have accrued.  (revised per Amendment 02)  This is expected to occur on or 
before October 2018. 
When 460 adjudicated MACE events have occurred, an interim analysis will be conducted on 
MACE events (see Section 9.7.3).  It will be conducted to establish whether the primary safety 
objective (MACE noninferiority) has been achieved.  This analysis will be performed by an 
independent statistician and governed by an independent Data Monitoring Committee (DMC)
and is anticipated to occur on or before (approximately) July 2017.  (revised per 
Amendment 02).  If the primary safety objective has been achieved, the trial will continue for 
evaluation of additional endpoints as delineated in the objectives.
An overview of the study design is presented in Figure 1.

9.1.1
Prerandomization Phase
The Prerandomization Phase will last up to 30 days and consist of 1 visit during which subjects 
will be screened for eligibility and continue until randomization or exclusion.  The purpose of the 
Prerandomization Phase is to obtain informed consent and to establish protocol eligibility.  
Informed consent will be obtained after the study has been fully explained to each subject and 
before the conduct of any screening procedures or assessments.  Procedures to be followed when 
obtaining informed consent are detailed in Section 5.3.
Subjects must be overweight or obese with CV disease or other CV risk factors and must meet 
all inclusion and exclusion criteria.  The Screening Disposition case report form (CRF) page 
must be completed to indicate whether the subject is eligible to participate in the study and to 
provide reasons for screen failure, if applicable.

a 1:1 ratio to receive lorcaserin HCl 10 mg BID or placebo.
9.1.2.1
Treatment Period
The Treatment Period will last for approximately 5 years with approximately 18 visits.  The first 
dose should be taken at the Randomization visit (Visit 2).  (revised per Amendment 01) During 
the Treatment Period, subjects will continue treatment with the dose of lorcaserin HCl 10 mg or 
placebo BID in blinded fashion.
9.1.2.2
Follow-up Period
For subjects who remain in the study through the Sponsor Notification of Study Completion, the 
Follow-up Period will begin immediately after the EOT assessments have been completed, and 
will consist of 1 EOS visit, occurring 30 days 10 days after last dose of study drug for subjects 
who complete study treatment.

procedures for subjects who prematurely discontinue study drug.
9.2
DISCUSSION OF STUDY DESIGN
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.
A placebo control is 
considered appropriate because study drug treatment will be adjunctive to all standard-of-care 
therapies for background CV risk factors.
The population selected for the study targets high CV risk obese patients in order to demonstrate 
that BELVIQ (lorcaserin HCl) does not cause an increase in MACE events and may even reduce 
MACE+ events within the study period. There is significant linkage between obesity and 
diabetes and most T2DM subjects are obese. T2DM with CV risk factors confers greater CV 
risk. Inclusion of 50% of subjects with diabetes with additional CV risk factors in the total study 
population will ensure that the population is representative of patients with more advanced 
diabetes, and may also help to establish the CV safety profile for BELVIQ (lorcaserin HCl) if a
diabetes indication is pursued in the future. In addition, the sample size of this population allows 
the evaluation of BELVIQ’s short term effects on glycemic control.
The sample size of nondiabetic subjects (50% of the total study population) allows further 
confirmation of BELVIQ’s benefit in delaying conversion from nondiabetes to diabetes and 
further explores BELVIQ’s benefit in delaying diabetes progression in the long follow-up study 
duration. In addition, it may also help to establish the clinical significance of reduction of 
conversion to diabetes by the assessment of T2DM-specific induced renal impairment and its 
progression.

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, stratified by the presence of established CV disease (roughly 80%) or CV risk 
factors without established CV disease (approximately 20%). Each treatment group will receive 
either lorcaserin HCl or placebo BID.  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 (Visit 2), 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.

Utilization of dose reduction will be recorded in the applicable subject’s chart for source 
documentation purposes and captured in the eCRF.
Dose Interruption for Renal and Hepatic Abnormalities 
Severe Renal Dysfunction (revised per Amendment 01)
o
If eGFR <30 mL/min/1.73 m2, continue study drug but repeat eGFR within 1 week. 
o
If eGFR still <30 mL/min/1.73 m2 on repeat measurement, temporarily discontinue 
study drug. 

Follow-up after study drug discontinuation due to severe renal dysfunction: 
o
Recheck eGFR per clinical practice 
o
Consider re-initiation of study drug with resolution of reversible cause of acute 
kidney injury and when eGFR ≥30ml/min/1.73 m2 on at least 2 consecutive 
measurements spaced at least 1 week apart. 
Significant Hepatic Abnormalities 

Temporarily discontinue study drug if there is any evidence for hepatic dysfunction defined 
as either:
o
Clinical evidence for severe acute hepatitis associated with either ALT elevation 
>5x upper limit of normal (ULN) or total bilirubin level >3xULN.
o
Known chronic hepatic disease with an increase in the Child-Pugh Score to ≥10. 
http://www.mdcalc.com/child-pugh-score-for-cirrhosis-mortality/

Confirm the new or worsening hepatic dysfunction with repeat liver function tests (LFTs)
and determine its cause. Repeat LFTs weekly until the clinical picture resolves and 
laboratory values are stable for at least 2 weeks, or until it is determined that the hepatic 
dysfunction is chronic.

Restarting of Study Drug
Study drug should be restarted at the standard BID dosing unless study drug was discontinued 
due to an AE considered related to the study drug.  Those individuals can be started on QD
dosing as per the instructions above.  Subjects discontinued from study drug due to a serious or
severe AE considered to be related to study drug by the investigator should not be restarted on 
study drug.  Prior to restarting study drug for subjects who have been discontinued, consideration 
should be given as to whether the subject has developed any conditions (eg, change in medical 
status, use of concomitant medications, lack of contraception) exclusionary to taking study drug. 
(see Section 9.4.7.2 for specific instructions concerning restart of study drug for individuals 
requiring a second nonstudy drug serotonergic agent).

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 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 9.5.4.6.  If possible, before breaking the blind, the investigator 
should consult with the sponsor or designee to ascertain the necessity of breaking the code.
An interim analysis will be conducted during the trial when 460 adjudicated MACE events have 
been reported.  To maintain the integrity and credibility of the trial, procedures will be 
implemented to ensure the DMC and independent statistician have sole access to evolving 
information from the clinical trial regarding comparative efficacy and safety data aggregated by 
treatment group.  Full details of the DMC procedures including primary responsibilities of the 
DMC, its relationship with other trial components, its membership, and the purpose and timing 
of its meetings will be documented in the DMC Charter.  These details will also include 
procedures to ensure confidentiality and proper communication (as outlined in the Study 
Integrity Charter), the safety and statistical monitoring guidelines to be implemented by the 
DMC, and an outline of the content of the closed reports  and open reports  that will be provided 
to the DMC.  (revised per Amendment 02)

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.
Any antidiabetic agents taken by diabetic subjects prior to randomization must be stabilized for 
3 months with minimal changes.  Minimal changes are defined as no change in insulin dose 
10% of daily dose, no change in dose frequency, no add-on or reduction of anti-diabetic agents,
and the subject has not been hospitalized due to hypo-, or hyperglycemic events.

ergotamine, methysergide, or cabergoline) lorcaserin HCl should be stopped.  
(revised per Amendment 01)  If the subject discontinues treatment with the other 
agent, lorcaserin HCl may be restarted as long as the other agent has been 
discontinued for at least 1 month. (revised per Amendment 01)
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, 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.  (revised per Amendment 01)  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:
o
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.

Use of serotonergic drugs:
o
The US Prescribing Information for BELVIQ (lorcaserin HCl) allows for concomitant 
use of serotonergic drugs with extreme caution, noting that if concomitant 
administration of lorcaserin HCl with an agent that affects the serotonergic 
neurotransmitter system is clinically warranted, extreme caution and careful 
observation of the patient is advised, particularly during treatment initiation and dose 
increases.  
For the purposes of this clinical study, any drug that has a risk for serotonin syndrome in its 
label, or that has been associated with a risk of serotonin syndrome in the medical literature, 
including OTC drugs, should be used only when clearly indicated and within approved dose 
ranges and durations as specified in the appropriate labeling.  More than 1 additional 
serotonergic agent is prohibited in combination with lorcaserin HCl.
See Section 9.4.8 for 
instructions related to study drug discontinuation and restart if a subject requires treatment with a 
second nonstudy drug serotonergic agent.  (revised per Amendment 01)

Treatment Compliance
Records of treatment compliance for each subject will be kept during the study.  CRAs will 
review treatment compliance during site visits and at the completion of the study.

During this study, the endpoints of MACE and MACE+ will need to be reported in an expedited 
fashion by investigators to the Clinical Endpoint Committee (CEC) and to the Eisai Product 
Safety Department.  MACE/MACE+ events will be recorded on the Adverse Event (AE) case 
report form, but these events will not be considered as AEs, nor will they be recorded as serious 
adverse events (SAEs) in the clinical trial database or be required to be reported to regulatory 
authorities in an expedited timeframe, with the exception of MACE or MACE+ events that are 
considered by the investigator to be at least possibly related to the study drug (ie, where there is 
evidence to suggest a causal relationship).  (revised per Amendment 01)
Details of which events to report, how to report, and the required supporting documentation will 
be detailed in a separate manual provided to the sites.
In order to reduce intra- and intersite variability, the CEC will centrally review each potential 
MACE and MACE+ event to ensure standardization of data collection and interpretation of such 
events reported throughout the study.  The CEC will determine whether each potential event 
meets criteria for MACE or MACE+.  The CEC will remain blinded to treatment allocation and 
its activities and the criteria for classification of MACE/MACE+ events will be documented in 
the CEC Charter.
CONVERSION TO DIABETES
HbA1c and FPG will be measured in blood samples collected at Screening, Baseline, and 
specified timepoints throughout the study.

AES AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
(revised per Amendment 01)
An adverse event (AE) is any untoward medical occurrence in a subject 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 lorcaserin HCl. 
The criteria for identifying AEs 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
●
Any new disease or exacerbation of an existing disease 
●
Any deterioration in nonprotocol-required measurements of a laboratory value or other 
clinical test (eg, 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, whether prescribed in the protocol or not.
A laboratory result should be considered by the investigator to be an AE if it:
●
Results in the withdrawal of study drug
●
Results in withholding of study drug pending some investigational outcome
●
Results in an intervention, based on medical evaluation (eg, potassium supplement for 
hypokalemia)
●
Results in any out-of-range laboratory value (Sponsor’s Grading for Laboratory Value 
provided as reference in Appendix 3) that in the investigator’s judgment fulfills the 
definitions of an AE with regard to the subject’s medical profile
(revised per 
Amendment 01)
All AEs observed during the study will be reported on the 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 end of the study. (revised per Amendment 01)
MACE and MACE+ events and other study-specific AEs of interest will be followed until EOS.
(revised per Amendment 01)
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.  Any laboratory abnormality considered 
to constitute an AE should be reported on the Adverse Event CRF.

Eisai
FINAL (v7.0):  30 Mar 2017
Page 61 of 122

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. 
(revised per Amendment 01)
All AEs must be followed for at least 30 days after Sponsor Notification of Study Completion, or 
until resolution, whichever comes first.  (revised per Amendment 01)
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 AES
AEs 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 SAEs and 
Other Events of Interest, Section 9.5.1.5 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
Causality will be based on the response to the following question:
Was there a reasonable possibility that the drug caused the adverse event? Yes/No

Where Yes = related and No = Not related
SAES AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS
(revised per Amendment 01)
A serious adverse event (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 1 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.
The study-specific events that are listed on the Reporting of Events Associated with Special 
Situations (Section 9.5.4.4) should always be considered as SAEs 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).  If the event does not meet other serious criteria, it should be reported under the 
serious criterion of Important Medical Event.  (revised per Amendment 01)
Study-specific AEs of interest which are always to be reported as SAEs are included in the list 
on the Reporting of Events Associated with Special Situations (Section 9.5.4.4). (revised per 
Amendment 01)
In addition to the list on the Reporting of Events Associated with Special Situations 
(Section 9.5.4.4), other 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; and any treatment-emergent significant laboratory abnormality (revised per 
Amendment 01)

evidence to suggest a causal relationship). (revised per Amendment 01)
All MACE and MACE+ events are to be reported on the AE CRF and the MACE/MACE+ 
section of the CRF, but will not be considered as AEs.
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:

Planned hospitalizations required by the protocol

Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed post study drug administration)

(revised per Amendment 01)

Hospitalization for routine maintenance of a device (eg, battery replacement) that was 
in place before study entry

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 AEs and Other Events of Interest [Section 9.5.1.5]) and the CRF Completion Guidelines.  In 
these instances, the AE corresponding to the laboratory abnormality will be recorded on the 
Adverse Event CRF.
Laboratory abnormalities meeting the criteria of SAEs (see SAEs and Other Events of Interest 
[Section 9.5.1.5]), must be reported to the sponsor in the same manner as SAEs (see Reporting of 
SAEs [Section 9.5.4.1]).  In addition, the laboratory report must be provided to the sponsor, as 
regionally required.
VITAL SIGNS AND HEIGHT/WEIGHT MEASUREMENTS
Vital sign measurements (ie, systolic and diastolic BP [mmHg], pulse [beats per minute], and 
weight (kg) will be obtained at the visits designated on the Schedule of Procedures/Assessments 
(Table 4) by a validated method.  BP and pulse will be measured after the subject has been

in centimeters (cm).  Each measurement will be made and recorded 3 times at each scheduled 
assessment; the average of the 3 values will be reported. In order to standardize the method 
used, measurements should be obtained as follows: 
Waist Measurement:  waist measurement will be done according to the National Heart, Lung, 
and Blood Institute (NHLBI) Guideline in the Identification, Evaluation, and Treatment of 
Overweight and Obesity in Adults.13  To define the level at which the waist circumference is 
measured, a bony landmark is first located and marked.  The subject stands and the examiner, 
positioned at the right of the subject, palpates the upper hip bone to locate the right iliac crest.  
Just above the uppermost lateral border of the right iliac crest, a horizontal mark is drawn, and 
then crossed with a vertical mark on the midaxillary line.  The measuring tape is placed in a 
horizontal plane around the abdomen at the level of this marked point on the right side of the 
trunk.  The plane of the tape is parallel to the floor and the tape is snug, but does not compress 
the skin.  The measurement is made at a normal minimal respiration (Figure 2).
Hip Measurement:  With a tape measure, measure the distance around the largest extension of 
the buttocks.

PHYSICAL EXAMINATIONS
Physical examinations (targeted or symptom directed) will be performed as designated on the
Schedule of Procedures/Assessments (Table 4).  A targeted physical examination will include 
evaluations of the heart and lungs, abdomen, and limbs. Examinations of other systems will only 
be required in the presence of clinical symptoms related to this region.  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.
ELECTROCARDIOGRAMS
ECGs will be obtained as designated on the Schedule of Procedures/Assessments if subjects 
come to the study visit in person (Table 4). 
Newly occurring Q-waves will be reported and evaluated as potential silent MI; suspected events 
will be adjudicated by the CEC.
An ECG abnormality may meet the criteria of an AE as described in this protocol (see AEs and 
Other Events of Interest [Section 9.5.1.5]) and the CRF Completion Guidelines.  In these 
instances, the AE corresponding to the ECG abnormality will be recorded on the Adverse Events 
CRF.
ECG abnormalities meeting the criteria of SAEs (see SAEs and Other Events of Interest 
[Section 9.5.1.5]), must be reported to the sponsor in the same manner as SAEs (see Reporting of 
SAEs [Section 9.5.4.1]).  In addition, the ECG report must be provided to the sponsor, as 
regionally required.
ECHOCARDIOGRAM
Echocardiograms will be obtained on a subset of approximately 3600 subjects at selected sites as 
designated on the Schedule of Procedures/Assessments (Table 4).  Acquisition of new ECHO
data in all subjects will cease when at least 1000 subjects have completed the Month 36
echocardiographic assessment.  (revised per Amendment 02)
To maintain consistency with echocardiographic assessments conducted in the lorcaserin HCl
Phase 3 program, and to allow pooling of Phase 3 data with that from the proposed study, the 
categories for echocardiographic assessments of aortic and mitral valve regurgitation will remain 
the same as in the Phase 3 program.  Valvular regurgitation as assessed on substudy 
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.
(revised per 
Amendment 01)  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.

In this study, echocardiographic images will be acquired in a subset of subjects to establish the 
cardiac
safety of lorcaserin HCl.  Standardized training will be provided for all
echocardiographers, and will implement centralized procedures for collecting, analyzing, and
reporting echocardiographic data. All echocardiograms will be over-read by 2 blinded central 
readers (primary and secondary).
Baseline echocardiograms will be performed in between Visits 1 and 2, after the results of 
screening assessments have been obtained but prior to randomization, and subject eligibility is 
confirmed.
PREGNANCY TEST
During Screening, blood samples for pregnancy testing will be collected for women of 
childbearing potential (as defined in Section 9.3.1, Inclusion Criterion No. 5).  A urine 
pregnancy test will be performed at the time of randomization.
TOBACCO HISTORY AND USE
History of tobacco use will be captured at Baseline.  Changes in smoking status will be captured 
yearly thereafter.

Notes:  Upon Sponsor Notification of Study Completion (ie, trial completion), sites will be instructed to bring subjects who remain on treatment for an EOT visit.  An EOS visit will occur 
approximately 30 days later for subjects on treatment at Sponsor Notification of Study Completion.
Subjects who prematurely discontinue study drug are to complete the EOT visit within approximately 30 days, and will continue in the study for all subsequent study visits until study completion.  
If the next scheduled visit after EOT assessments is <30 days, subjects can skip that visit and return for the next subsequent visit (eg, if the EOT is 15 days prior to the scheduled Month 36 visit, 
they can skip Month 36, and come in at Month 40).  All procedures and assessments should be performed at subsequent visits until EOS except where footnoted in assessment column.  Upon 
Sponsor Notification of Study Completion, subjects who prematurely discontinued study medication ≥30 days before will return for an EOS visit.  Subjects who are still being followed in the study 
but who discontinued study medication within 30 days of Sponsor Notification of Study Completion will return for an EOS visit approximately 30 days after their last dose of study medication.

Appropriateness of Measurements
All clinical assessments are standard measurements used to meet the requirements for conducting 
a CVOT.
The safety assessments to be performed in this study, including hematology analyses, blood 
chemistry tests, urinalysis, vital signs and assessment of AEs, are standard evaluations to ensure 
subject safety.  Serial echocardiogram assessments on a subset of subjects at selected sites are 
included in the study per requirement by the FDA. 
9.5.4
Reporting of SAEs, Hypoglycemia, Pregnancy, and Other Events of Interest
9.5.4.1
Reporting of SAEs
All SERIOUS ADVERSE EVENTS, regardless of their relationship to study treatment, 
must be reported as soon as possible but no later than 24 hours from the time the 
investigator becomes aware of the event.
Serious adverse events, regardless of causality assessment, must be collected through the end of 
study.  For those subjects taking study drug at the time of study completion (“Sponsor 
Notification of Study Completion”), SAEs should be collected for 30 days after the last dose. 
(revised per Amendment 01)
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 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 be as complete 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 24 hours 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 report.
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 or 
designated CRO to be filed in the sponsor’s Trial Master File.

Reporting of Hypoglycemia
Patient-reported episodes of hypoglycemia or decreased blood sugar should be captured on the 
eCRF according to the following guidelines:

Mild 
hypoglycemia 
is 
defined 
as 
capillary 
glucose 
≥55
to
<65
mg/dL 
(≥3.0 - <3.3 mmol/L) that the subject is able to treat himself/herself; or, if glucose is not 
measured, symptoms of hypoglycemia that resolve with administration of oral 
carbohydrates. 

Moderate hypoglycemia is defined as capillary glucose <55 mg/dL (<3.0 mmol/L) that 
the subject is able to treat himself/herself.

Severe hypoglycemia is defined as a symptomatic capillary glucose <40 mg/dL
(<2.2mmol/L) OR a capillary glucose ≤65 mg/dL AND needed help from another person 
OR required intravenous glucose

Catastrophic hypoglycemia is defined as severe hypoglycemia that resulted in 
life-threatening injury to the subject or another person, hospitalization, and/or death.  
This should be reported as a SAE.
Additionally, adverse events of hypoglycemia should be further specified in the eCRF adverse 
event term as “symptomatic” or “asymptomatic”.  
See Section 9.4.7.2 for directions on the recommendations for possible adjustment to 
antihyperglycemic medication doses in response to reported episodes of hypoglycemia.
9.5.4.3
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 Reporting of SAEs [Section 9.5.4.1]).
Pregnancies or exposure to study drug through breastfeeding must be reported as soon as 
possible but no later than 24 hours 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.  All pregnancies must be 
followed to outcome.  The outcome of the pregnancy must be reported as soon as possible but no 
later than 24 hours from the date the investigator becomes aware of the outcome.

Reporting of Events Associated with Special Situations
(revised per Amendment 01)
REPORTING OF AES ASSOCIATED WITH STUDY DRUG OVERDOSE, MISUSE, ABUSE, OR 
MEDICATION ERROR
AEs 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 (revised per Amendment 01)
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 site personnel or the
subject
All AEs associated with an overdose should be captured on the Adverse Event CRF.  AEs
associated with overdose, misuse, abuse, or medication error should be reported using the 
procedures detailed in Reporting of SAEs (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 in an 
expedited manner but should be noted as nonserious in the report and on the Adverse Event 
CRF.
(revised per Amendment 01)
REPORTING OF STUDY-SPECIFIC EVENTS
All study specific AEs of interest should be reported using the procedures detailed in Reporting 
of SAEs (Section 9.5.4.1).  (revised per Amendment 01)
The Study-specific events below should always be considered as SAEs 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),  If the event does not meet other serious criteria, then it should be 
reported under the serious criteria of Important Medical Event.  (revised per Amendment 01)

moderate or greater grading for all other valvular lesions (eg, mitral regurgitation, aortic 
stenosis) on imaging in subjects without any valvular disease at Baseline.  Worsened 
valvular disease is defined in subjects who have existing FDA defined valvulopathy at 
Baseline increase in severity of regurgitation or stenosis as demonstrated by objective 
assessments (eg, imaging assessments such as magnetic resonance imaging [MRI], 
echocardiography, or cardiac catherization). (revised per Amendment 01)

subjects without any pulmonary hypertension at Baseline.  Worsening pulmonary 
hypertension is defined in subjects who have documented objective assessment 
pulmonary hypertension at Baseline as an increase in pulmonary artery systolic pressure, 
or mean artery pressure by more than 10 mmHg. (revised per Amendment 01)
9.5.4.5
Expedited Reporting
The sponsor must inform investigators (or, as regionally required, the head of the medical 
institution) 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.
9.5.4.6
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.
9.5.4.7
Regulatory Reporting of AEs
AEs 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.
All studies that are conducted within any European country will comply with European GCP
Directive 2005/28/EC and Clinical Trial Directive 2001/20/EC.  All SUSARs will be reported, as 
required, to the competent authorities of all involved European member states.
9.5.5
Completion/Discontinuation of Subjects
9.5.5.1
Premature Discontinuation of Study Drug
A subject may decide to discontinue receiving the study drug at any time for any reason.  The 
investigator may discontinue a subject from receiving the study drug at any time for safety or 
administrative reasons.  The reason for premature discontinuation of study drug will be 
documented.
Discontinuation from receiving study drug does not mean that the subject is withdrawn from the 
study.  Subjects who prematurely and permanently discontinue study drug are to complete the 
EOT visit within approximately 30 days as defined in the Schedule of Procedures/Assessments 
(Table 4).  (revised per Amendment 01)  Subjects who prematurely discontinue study drug will 
continue in the study for all subsequent study visits until study completion and are to complete 
visit procedures as indicated in Table 4.  It is preferred that these visits are conducted in person.

However, if the subject is unable to attend a visit in person, a telephone visit may be performed.  
The outcome of the telephone visit must be clearly documented in the source record.  At a 
minimum, the site should attempt to have the subject return for an in-person clinic visit at least 
once per year. 
Upon Sponsor Notification of Study Completion, subjects who prematurely discontinued study 
medication ≥30 days before will return for an EOS visit.  Subjects who are still being followed in 
the study but who discontinued study medication within 30 days of Sponsor Notification of 
Study Completion will return for an EOS visit approximately 30 days after their last dose of 
study medication. (revised per Amendment 01)
Unless he or she withdraws consent for any type of follow-up contact, a subject who has ceased 
to return for visits may 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.  This information will be recorded in the CRF.  
Patient finder services will be utilized to identify updated contact information when the site 
cannot locate a missing subject.
For subjects who prematurely discontinue from study drug, the reasons will be documented in 
the CRF and source documentation.  Study drug disposition information will be collected on the 
Early Discontinuation from Study Drug CRF.
Restart of Study Drug 
Whenever possible, restart of study drug should be encouraged. Subjects discontinued from 
study drug due to a serious or severe adverse event considered to be related to study drug by the 
investigator should not be restarted on study drug.  Prior to restarting study drug on subjects who 
have been discontinued, consideration should be given as to whether the subject has developed 
any conditions (eg, change in medical status, use of concomitant medications, lack of 
contraception) exclusionary to taking study drug. See specific instructions in Section 9.4.5.1 for 
instructions on dosing when restarting study drug and Section 9.4.7.2 for instructions concerning 
restart of study drug for individuals requiring a second non study drug serotonergic agent.  Even 
if a premature EOT visit was completed due to the discontinuation of study drug, this should not 
prevent complete study follow-up procedures including the final EoT/Closing Visit, following 
restart of randomized treatment.  (revised per Amendment 01)
9.5.5.2
Discontinuation from Study Procedures/Withdrawal of Consent
A subject may elect to discontinue all participation in the study at any time for any reason.  
(revised per Amendment 01)
Only subjects who refuse any and all types of contact (eg, visits, telephone calls, medical record 
reviews) will be considered to have withdrawn consent for all clinical follow-up.  It is expected 
that this would be extremely unusual.  The site must contact the TIMI Hotline to confirm 
withdrawal of consent, at which time the Withdrawal of Consent CRF will be made available for

completion.  A final assessment for vital status using publically available data will be performed 
at the end of the study for all subjects who withdraw consent for all clinical follow-up, when 
allowed by law, regulation, or local authorities.
The investigator may also withdraw a subject from the study only in the event of exceptional 
circumstances.  This must be documented by the site, signed by the investigator, and reviewed by 
the sponsor/designee before it is considered to take effect.
All subjects who prematurely discontinue all study procedures (ie, withdraw consent) are to 
complete the EOS Visit procedures indicated in the schedule of procedures/assessments
(Table 4).
For subjects who prematurely discontinue from the study, the reasons will be documented in the 
CRF and source documentation.  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 drug.
AEs associated with abuse or diversion will be appropriately reported as AEs and monitored per 
Section 9.5.1.5.  Abuse is always to be captured as an AE.
Sites will be assessed for the appropriateness of study drug storage and retrieval at the time of 
site selection.  Required policies and procedures will be clearly communicated to the site to 
assess the site’s capabilities and adherence to storage, dispensing, reconciliation, and retention of 
study drug.
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.

Primary Safety and and Key Secondary Efficacy Analyses (revised per Amendment 02)
The primary endpoints, MACE, and MACE+, will be analyzed using a Cox proportional hazards 
model that includes factors for treatment and stratification variable (presence of established CV 
disease or CV risk factors without established CV disease).  (revised per Amendment 02) For 
secondary and exploratory endpoints a 2-sided α = 0.05 significance level will be used.  The 
MACE analysis (“interim” analysis) will be conducted when 460 adjudicated MACE events have 
been recorded; the other analyses will be conducted when 1401 adjudicated MACE+ events have 
been recorded, and the study has completed.  (revised per Amendment 02)
Sequential Gatekeeping Testing Procedure (revised per Amendment 02)
The following closed sequential gatekeeping testing procedure (SGTP) will be used to control 
the family-wise error rate (FWER) at α = 0.05 (2-sided) in testing the 2 primary endpoints
(MACE and MACE+) and 1 key secondary endpoint, conversion to T2DM.  (revised per 
Amendment 02)  
Let H01 be the gatekeeping null hypothesis for noninferiority testing of the MACE endpoint 
using a noninferiority margin of 1.4.
Let H02, and H03 be the null hypotheses for superiority testing: MACE+ and conversion to 
T2DM, respectively.  (revised per Amendment 02)
The SGTP testing hierarchy is presented below.  (revised per Amendment 02)

STEP1:  At the interim analysis, test the noninferiority hypothesis for MACE, H01 (α = 
0.025, 1-sided).  If H01 is rejected, then proceed to STEP2, otherwise stop testing and 
the trial will be stopped.

STEP2:  At study completion, the hypotheses H02 (α = 0.05, 2-sided), is tested first.  If 
the hypothesis is rejected, then proceed to test H03 (α = 0.05, 2-sided).  If H02 is not 
rejected, then testing stops at this point.

9.7.1.10 Safety Analyses
All safety analyses will be performed on the Safety Analysis Set.  The incidence of AEs 
(including changes from baseline in physical examination), out-of-normal-range laboratory 
safety test variables, abnormal ECG findings, along with change from Baseline in laboratory 
safety test variables, ECGs, and vital sign measurements summarized yearly by treatment group 
using descriptive statistics.
EXTENT OF EXPOSURE
Cumulative exposure to study drug will be summarized by the number and percentage of
subjects (remaining in study) exposed to study drug in days or other time units by treatment
group. In addition, the number of days or other time units of exposure will be summarized
descriptively as a continuous variable. The average dose and relative dose intensity (actual dose
administered divided by planned dose) will be summarized by month and overall study.
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).  AEs will be coded to the MedDRA lower level term (LLT) 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, having 
been absent at pretreatment (Baseline) or 
●
Re-emerges 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.
TEAEs will be summarized by treatment group on the Safety Analysis Set.  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 TEAEs will also be summarized by relationship to study drug 
(possibly related, probably related, and not related).
AEs will be summarized by the following subgroups:  age (<65 years, ≥65 years), sex (male, 
female), race (white, black, other), and T2DM at Baseline (with and without).

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 SAEs 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.
The incidence of AEs of interest will be summarized separately.  In addition, for each AE of 
interest, Kaplan-Meier curves and median time and 95% CI will be presented.  The Safety 
Analysis Set will be used for this analysis.
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 Safety Assessments (Laboratory 
Measurements), the actual value and the change from baseline to each postbaseline visit and to 
the EOT (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 will be summarized 
using frequencies (number and percentage of subjects), and changes from baseline to each 
postbaseline visit and to EOT 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 EOT.  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 3 (Sponsor’s Grading for Laboratory Values) 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.

Determination of Sample Size
A sample size of 12,000 subjects should provide the required power for the primary endpoints as 
follows:  (revised per Amendment 02)

For 460 MACE events to have occurred by approximately 43 months from start of the 
trial, providing 95% power to exclude a noninferiority margin of 1.4, assuming an annual 
background rate of 1.5%, 15-month accrual period, 5% annual drop-out rate, α = 0.025, 
and a 1-sided test

For 1401 MACE+ events to have occurred by approximately 54 months from the start of 
the trial, providing >85% power to detect a 15% risk reduction with lorcaserin HCl, 
assuming an annual background rate of 3.5%, 15-month accrual period, 5% annual 
drop-out rate, α = 0.05, and a 2-sided test (revised per Amendment 02)
Key Secondary Endpoint (revised per Amendment 02)

For 457 events of conversion to T2DM in subjects who are prediabetic at the time of 
enrollment (~33%) to have occurred by approximately 54 months from the start of the 
study, providing 86% power to detect a 25% risk reduction with lorcaserin HCl, 
assuming an annual background rate of 4%, 15-month accrual period, 5% annual dropout 
rate, α = 0.05 and a 2-sided test.  (revised per Amendment 02)
9.7.3
Interim Analysis
There will be 1 interim analysis - when 460 adjudicated MACE events have occurred, the
primary analysis for MACE will be conducted.  This will be the analysis to rule out a hazard 
ratio of 1.4.  The study will continue to accrue events until the required number of MACE+ have
occurred.  (revised per Amendment 02)  Sensitivity analysis at study completion will be 
performed for the MACE endpoint after all the MACE+ events have accrued. (revised per 
Amendment 02)  At the time of MACE+ analyses, there will be approximately 600 MACE 
events.

CONFIDENTIAL
The interim analysis for MACE endpoint will be performed by an independent statistician and 
governed by an independent DMC and is anticipated to occur on or before (approximately) Jul 
2017.  (revised per Amendment 02)  The interim analysis will be conducted according to a DMC 
Charter to establish whether the MACE primary objective has been achieved.
To maintain the integrity and credibility of the trial, procedures will be implemented to ensure 
the DMC and independent statistician have sole access to evolving information from the clinical 
trial regarding comparative efficacy and safety data aggregated by treatment group.  Full details 
of the DMC procedures including primary responsibilities of the DMC, its relationship with 
other trial components, its membership, and the purpose and timing of its meetings will be 
documented in the DMC Charter.  These details will also include procedures to ensure 
confidentiality and proper communication (as outlined in the Study Integrity Charter), the safety 
and statistical monitoring guidelines to be implemented by the DMC, and an outline of the 
content of the closed reports and open reports that will be provided to the DMC.  (revised per 
Amendment 02)
At the interim analysis for MACE, the estimate of the hazard ratio of lorcaserin HCl to placebo 
and the corresponding 97.5% CI will be calculated.  Noninferiority between lorcaserin HCl and 
placebo will be declared if the upper limit of the 97.5% CI is less than or equal to the 
noninferiority margin of 1.4.  If the upper limit of the 97.5% CI is greater than 1.4, then 
lorcaserin HCl will be declared as not noninferior to placebo and the trial will stop.
If noninferiority between lorcaserin HCl and placebo is confirmed when 460 adjudicated MACE 
events are observed at approximately 43 months from the start of the study, then the study will 
be continued to observe 1401 MACE+ events at approximately 54 months from the start of the 
study, and a median treatment duration of 2.5 years have accrued. (revised per Amendment 02)  
The events for MACE+ and T2DM will be tested according to the SGTP described previously, 
upon study completion.

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 or appropriate study team member 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 (or if regionally required, the head of the medical institution) 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 (or, if regionally 
required, the head of the medical institution) 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 (or if regionally 
required, the head of the medical institution) 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.

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 the 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 correction 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

11.6 RETENTION OF RECORDS
The circumstances of completion or termination of the study notwithstanding, the investigator 
(or if regionally required, the head of the medical institution or the designated representative) 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 or equivalent, 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 drug will be supplied to the 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.  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.

BACKGROUND 
AND 
RATIONALE 
FOR 
BIOMARKER 
RESEARCH
Obesity is a major risk factor for cardiovascular (CV) disease and other comorbidities, including 
diabetes, hypertension and hyperlipidemia.  Mounting evidence suggests that excess adiposity 
leads to increased morbidity via pathologic activation of inflammatory, and subsequently 
thrombotic and metabolic, pathways.  Observations supporting this mechanism are (1) that 
circulating mediators of inflammation, such as IL-6 and TNF-, participate in vascular injury 
and insulin resistance and (2) that several of these inflammatory mediators are secreted by 
adipocytes and adipose tissue-derived macrophages. These inflammatory processes are reflected 
in the correlation between adiposity and high sensitivity C-reactive protein (hsCRP), a strong 
marker of systemic and vascular inflammation associated with cardiovascular risk.  
Biomarkers of inflammation, metabolic dysregulation, and atherothrombosis have proven useful 
in identifying patients at risk of developing incident cardiovascular disease or diabetes as well as 
recurrent cardiovascular events in patients with stable atherosclerotic disease.  However, less is 
known about the potential of these biomarkers to make similar predictions in the setting of 
obesity.  
In addition to their role in prognostication, biomarkers that identify patients at higher risk for 
major adverse clinical outcomes can provide opportunity for guiding therapy. Patients at higher 
risk for cardiovascular events will have the greatest absolute risk reduction for a given relative 
risk reduction from a therapy and hence require a smaller number needed to treat to prevent a 
major event. Moreover, pathobiologically relevant biomarkers may identify a specific subset of 
patients who enjoy a larger relative risk reduction with a given pharmacotherapeutic 
intervention, and thus an even greater absolute risk reduction.
In addition to established biomarkers, new insights into the mechanistic pathways of obesity, 
diabetes and atherothrombosis have led to ongoing identification of novel cardiovascular and 
metabolic biomarkers. Using novel biomarkers that reflect the inflammatory, thrombotic, 
vascular, metabolic, and hemodynamic mediators of risk in patients with obesity and 
atherosclerotic risk factors, it may be possible to noninvasively characterize the participation of 
these different pathobiologic contributors in an individual patient and to monitor response to 
therapy. 
As such, this large study of well-characterized, obese subjects with CV risk factors (including 
diabetes) or established CV disease presents a unique opportunity to investigate circulating 
biomarkers for their pathobiologic insight as well as their value for risk stratification, therapeutic 
guidance and disease monitoring.  
The biomarker categories of interest for this study are broadly threefold: (1) those related to 
adiposity and metabolic dysregulation, (2) those related to dysglycemia and its complications, 
such as markers of glycation and renal dysfunction, and (3) those related to cardiovascular 
disease such as markers of atherosclerosis, ischemia, inflammation, thrombosis, hemodynamic 
stress and lipid dysregulation.  Selected examples for each of these areas follow below.

Markers of adiposity include adiponectin, interleukin-6 (IL-6), and resistin.  Adiponectin is 
secreted by adipocytes and is thought to play a role insulin sensitivity, lipid metabolism and 
inflammation.  Interestingly, in patients with established coronary disease (as determined by 
angiography), lower levels of adiponectin independently predicted major adverse cardiac events.  
Furthermore, in primary prevention populations, higher concentrations of adiponectin are 
associated with lower risks of cardiovascular disease and the risk of developing incident T2DM.  
IL-6 is a pro-inflammatory cytokine released by adipose tissue and is the major stimulant for 
hepatic generation of CRP.  Elevated levels of IL-6 were shown to be associated with increased 
risk of myocardial infarction in a large cohort of apparently healthy men.  A third adipokine, 
resistin, is thought to mediate insulin resistance and metabolic dysfunction.  Several studies have 
shown a relationship between resistin and major adverse cardiovascular events in both stable 
CAD and ACS populations.
Markers of dysglycemia and its sequelae include advanced glycation end products (AGEs), 
receptor for AGE (RAGE) and amino acids/metabolites. In patients with type II diabetes, 
elevated glucose levels lead to the dysregulation of physiologic metabolic pathways resulting in 
the production and accumulation of pathologic glycolated proteins, AGEs.  Elevated levels of 
AGE/RAGE have a variety of pathologic consequences such as oxidizing LDL, promoting 
atherosclerosis, and decreasing NO production.  Accordingly, AGE and RAGE have been shown 
to be prognostic markers for vascular disease in both diabetic and non-diabetic populations. 
Recent studies found that metabolite levels, specifically several branched chain and aromatic 
amino acids, can predict development of diabetes in normoglycemic individuals as well as 
incident cardiovascular disease.
Markers of cardiovascular disease and inflammation include high-sensitivity cardiac troponin, 
natriuretic peptides, hsCRP and fibrinogen.  Cardiac troponin, used commonly for diagnosis of 
AMI, has been shown to predict worsened cardiovascular outcomes in stable individuals with 
cardiovascular risk factors.  Elevated levels of natriuretic peptides (BNP or the amino-terminal 
fragment of the prohormone [NT-proBNP]) are closely associated with mortality and/or heart 
failure across a broad range of individuals, ranging from the general population to patients with 
acute coronary syndromes and decompensated heart failure.  An interesting interplay between 
natriuretic peptides and obesity has been recognized.  Natriuretic peptides levels are lower in 
obese patients compared with non-obese patients, an effect that may be mediated by increased 
clearance of natriuretic peptides by adipose tissue.  Conversely, it appears that natriuretic 
peptides may influence adipose tissue through moderation of lipid metabolism.  hsCRP, a marker 
of inflammation, predicts risk of first MI in healthy cohorts and future coronary events in stable 
patients.  Furthermore, elevated hsCRP levels in obesity are prognostic for development of 
cardiovascular disease and predictive of progression to type II diabetes. Fibrinogen, an acute 
phase reactant that has a central role in coagulation and platelet aggregation, is a marker for CV 
risk factors and predicts future cardiovascular disease.  Notably, lorcaserin hydrochloride therapy 
has been shown to decrease hsCRP and fibrinogen levels.  
The evaluation of biomarkers in subjects in this trial may provide important insight into 
pathobiology of obesity, diabetes and cardiovascular disease, improve our ability to risk stratify

OBJECTIVES
Aim 1: To evaluate the effect of treatment with lorcaserin hydrochloride compared to placebo on 
the change in baseline biomarkers of adiposity and metabolic dysregulation, dysglycemia and its 
complications, and CV risk (atherosclerosis, ischemia, inflammation, thrombosis, hemodynamic 
stress and lipid dysregulation) over the data acquisition period. 
We hypothesize that lorcaserin hydrochloride will improve circulating concentrations of 
biomarkers of these conditions/processes over time compared to placebo.
Aim 2: To evaluate the prognostic performance of established and novel biomarkers of adiposity 
and metabolic dysregulation, dysglycemia and its complications, and CV risk (atherosclerosis, 
ischemia, inflammation, thrombosis, hemodynamic stress and lipid dysregulation) individually 
and in combination (multimarker approach).  
We hypothesize that baseline biomarkers can identify subgroups of overweight or obese subjects 
at increased risk of major adverse cardiovascular outcomes and/or the development of diabetes.  
Furthermore, we hypothesize that a multi-marker approach can improve discrimination, 
accuracy, and net reclassification improvement of models predicting the development or 
progression of these disorders.  
Aim 3: To evaluate whether obese subjects identified at higher risk on the basis of biomarkers 
experience greater absolute and/or relative risk reduction in major adverse cardiovascular 
outcomes and/or the development of diabetes with lorcaserin HCl versus placebo. 
We hypothesize that subjects with the highest risk biomarker profiles will observe greatest 
benefit from treatment with lorcaserin hydrochloride.
Aim 4: To evaluate the prognostic significance of the change in the levels of established and 
novel biomarkers of adiposity, inflammation, hemodynamic stress, myocardial ischemia/necrosis 
and metabolism between baseline and 6 month, and whether changes in biomarker concentration 
identify subjects with greater benefit with lorcaserin HCl versus placebo.
We hypothesize that the change in levels of biomarkers between baseline and 6 months can 
identify subgroups of overweight or obese subjects at increased risk of major adverse 
cardiovascular outcomes and/or the development of diabetes, who are likely to derive greater 
benefit from treatment with lorcaserin HCl.

ETHICAL AND REGULATORY REQUIREMENTS
The principles for ethical and regulatory requirements for the study, including this biologics 
research component, are outlined in Section 5 of the main Clinical Study Protocol.
Informed consent
The biologic component of this study is optional and the patient may participate in other 
components of the main study without participating in the biologic component. The principal 
investigator(s) is responsible for ensuring that consent is given freely and that the patient 
understands that they may freely discontinue from the biologic aspect of the study at any time.
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 or its agents 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 biomarker samples will be coded.  
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 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 subjects or their physicians.

Biomarker data from the designated laboratory will be merged with the clinical database for 
statistical analysis.
The results from this biologic research may be reported in the CSR for the main study, or in a 
separate report as appropriate.
Some or all of the clinical datasets from the main study may be merged with the biologic data in 
a suitable secure environment separate from the clinical database.

STATISTICAL ANALYSIS PLAN
The biomarker analyses are exploratory in nature.  A sample size of approximately 
10,000 subjects (assuming 80%-90% participation) will provide 80% power to detect a relative 
risk of ≥1.2 for the primary endpoint of MACE and secondary endpoint of MACE+ for subjects 
above versus those below the median level of a biomarker.  These values are in keeping with risk 
estimates and interactions seen with other biomarkers and represent the thresholds of clinical 
importance.

BACKGROUND AND RATIONALE 
Subjects enrolled in this clinical study will have the option to have samples collected for genetic 
analysis. Genetic variations affect the risk of developing cardiovascular disease (eg, myocardial 
infarction) and metabolic disease (eg, diabetes).  Furthermore, genetic variants may alter the 
clinical efficacy and/or the safety profile of specific pharmacotherapy, either directly by 
affecting the pharmacokinetics or pharmacodynamics of the drug in question, or indirectly by 
altering the risk of developing outcomes the drug may prevent. 
2
GENETIC RESEARCH OBJECTIVES 
The objective of this research is to collect deoxyribonucleic acid (DNA) for research into 
genes/genetic variation that may influence response (eg, distribution, safety, tolerability and 
efficacy, including effects on obesity and the development and progression of secondary 
complications of obesity) to treatment with lorcaserin and genetic factors that may influence 
susceptibility to obesity, cardiovascular disease, and diabetes mellitus, and/or associated 
cardiovascular conditions and their risk factors.
The pharmacogenomic 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/resistance.  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.

GENETIC RESEARCH PLAN AND PROCEDURES 
3.1
Selection of genetic research population 
3.1.1
Study selection record 
All subjects will be asked to participate in this genetic research. Participation is voluntary and if 
a subject declines to participate there will be no penalty or loss of benefit. The subject will not be 
excluded from any aspect of the main study.
3.1.2
Inclusion criteria 
For inclusion in this genetic research, subjects must fulfill all of the inclusion criteria described 
in the main Clinical Study Protocol and: 

Provide informed consent for the genetic sampling and analyses. 
3.1.3
Exclusion criteria 
Exclusion from this genetic research may be for any of the exclusion criteria specified in the 
main Clinical Study Protocol or any of the following: 

Previous bone marrow transplant 

Whole blood transfusion within 120 days of genetic sample collection

3.1.4
Discontinuation of subjects from this genetic research 
Subjects may withdraw from this genetic research at any time, independent of any decision 
concerning participation in other aspects of the main study. Voluntary discontinuation will not 
prejudice further treatment. Procedures for discontinuation are outlined in the main Clinical 
Study Protocol. 
3.2
Collection of samples for genetic research 
The blood sample (10 ml EDTA) for genetic research will be obtained from the subjects at 
Visit 2 (Randomization/Baseline). Although genotype is a stable parameter, early sample 
collection is preferred to avoid introducing bias through excluding subjects who may withdraw 
due to an adverse event (AE). If for any reason the sample is not drawn at baseline, it may be 
taken at any visit until the last study visit at the discretion of the investigator and site staff.
Only 1 sample should be collected per subject for genetics during the study. Samples will be 
collected, labeled, stored and shipped as detailed in the Laboratory Manual of Operations 
3.3
Coding and storage of DNA samples 
No subject-identifying information (eg, initials, date of birth, government identifying number) 
will be associated with the sample.  The DNA samples 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 key linking the sample ID to the subject 
number will be maintained separately from the sample. Laboratory personnel performing genetic 
analysis will not have access to the key.  
All genetic samples will be stored under secure conditions with restricted access at Eisai, the 
designated vendor, and/or a contracted third party working with them on this study. Samples will 
be stored for up to 20 years after the completion of the study (defined as submission of the 
clinical study report [CSR] 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.
3.4
Genetic testing
There are genetic variants that increase the risk of the development of particular disease states 
(eg, degrees of obesity, cardiovascular disease, and type 2 diabetes mellitus), and lorcaserin may 
offer particular benefit among patients with these polymorphisms.  Genes will be evaluated both 
in relation to the disease state and to the properties of the study drug, and testing may include:
1. Body mass index and obesity: FTO, BDNF, MC4R. 
2. Cardiovascular disease as well as the risk of recurrent events: CDKN2A, SORT1, and 
CXCL12; additionally, a genetic risk score derived from 13 common variants has been 
successfully used to stratify risk for incident cardiovascular disease and MI in prospective

cohorts.  An additional 13 loci have now been identified, and these composite scores can 
also be used.
3. Development and severity of type 2 diabetes mellitus: TCF7L2, WFS1, and KCNQ1 as 
well as a composite genetic score will be evaluated.
4. Drug disposition and putative drug target: HTR2C.
5. Unbiased genetic studies may add further understanding of the mechanisms related to 
degrees of obesity, cardiovascular disease, and type 2 diabetes mellitus as well as 
lorcaserin’s modification of these particular entities.  Discovery studies using a gene 
array could be performed.

ETHICAL AND REGULATORY REQUIREMENTS 
The principles for ethical and regulatory requirements for the study, including this genetics 
research component, are outlined in the main Clinical Study Protocol. 
4.1
Informed consent 
The genetic component of this study is optional and the subject may participate in other 
components of the main study without participating in the genetic component. To participate in 
the genetic component of the study the subject must sign and date both the consent form for the 
main study and the genetic component of the study. Subjects may freely discontinue from the 
genetic aspect of the study at any time. 
4.2
Subject data protection 
Individual genotype results will not be provided to subjects, any insurance company, any 
employer, their family members, general physician or any other third party, unless required to do 
so by law. 
Samples will only be used for the purposes described in this protocol.  Laboratories contracted to 
perform the analysis will not retain rights to the samples beyond those necessary to perform the
specified analysis and will not transfer or sell those samples.  
5
DATA MANAGEMENT 
Any genotype data generated in this study will be in appropriate secure system within Eisai, the 
designated vendor, and/or a contracted third party working with them on this study.   
Steps will be taken 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:

STATISTICAL METHODS AND DETERMINATION OF SAMPLE SIZE 
The number of subjects that will agree to participate in the genetic research is unknown.  It is 
therefore not possible to establish whether sufficient data will be collected to allow a formal 
statistical evaluation or whether only descriptive statistics will be generated. A statistical analysis 
plan will be prepared where appropriate.
