SYNOPSIS
Name of Sponsor: Sunovion Pharmaceuticals Inc. 
Name of Investigational Product: Dasotraline (SEP-225289) 
Title of Study: An Open-label, Flexibly-dosed, Multicenter, Extension Study of Dasotraline to 
Evaluate Long-term Safety and Tolerability in Adults with Binge-eating Disorder 
Proposed Indication: Binge-eating Disorder 
Study Centers: ~ 61 clinical sites in the United States 
Planned Study Period: 35 months 
Study Objectives: 
Primary: To evaluate the long-term safety and tolerability of flexibly-dosed dasotraline (4, 6, or 
8 mg/day) in adults with binge-eating disorder (BED) who have completed a prior dasotraline study in 
BED by: 
•
The incidence of adverse events (AEs), discontinuations due to AEs, and serious AEs
(SAEs)
•
The frequency and severity of suicidal ideation and suicidal behavior using the
Columbia - Suicide Severity Rating Scale (C-SSRS)
•
Changes in 12-lead electrocardiograms (ECGs), vital signs, body weight, body mass index
(BMI), and clinical laboratory results
Secondary: 
•
To assess potential withdrawal effects of dasotraline using the following assessments
(administered during the withdrawal period):
− 
Cocaine Selective Severity Assessment (CSSA)
− 
Discontinuation-Emergent Signs and Symptoms (DESS) Scale
− 
Symptoms of anxiety utilizing the Hamilton Anxiety Rating Scale (HAM-A)
− 
Symptoms of depression utilizing the Montgomery-Asberg Depression Rating Scale
(MADRS) 
•
To assess the abuse potential of dasotraline utilizing a comprehensive abuse potential
monitoring plan (APMP)
•
To evaluate the long-term effectiveness of flexibly-dosed dasotraline in the treatment of
adults with BED as measured by the following:
− 
Eating Disorder Examination Questionnaire (EDE-Q) modified
− 
Binge-eating Clinical Global Impressions - Severity (BE-CGI-S)

• 
To assess subject-reported health status using the Medical Outcomes Study 12-Item Short 
Form Survey Instrument (SF-12)1 
Study Design: This is a Phase 3, 12-month, multicenter, open-label, flexibly-dosed, safety study in 
adults with BED. This study is projected to enroll approximately 500 subjects based on the number of 
subjects expected to complete treatment in the core studies (ie, SEP360-221 or SEP360-321). 
Informed consent will be obtained from all subjects after all procedures from the core study have been 
completed and before any study procedures unique to this study are performed. Safety and tolerability 
will be monitored throughout the study by AE reports, physical and neurological examinations, 12-lead 
ECG, vital signs, body weight, BMI, clinical laboratories (hematology, chemistry, urinalysis, 
hemoglobin A1c, and lipid panel), and C-SSRS. Effectiveness will be evaluated using the BE-CGI-S, 
EDE-Q modified, and SDS. Subject-reported health status will be assessed using the SF-12 (subjects 
from Study SEP360-221 only). Assessment of potential withdrawal effects of dasotraline will be 
conducted via administration of the CSSA, DESS, HAM-A, and MADRS at the end of treatment and 
during the 3-week study medication withdrawal period. 
A comprehensive Abuse Potential Monitoring Plan (APMP; see Section 24) for dasotraline designed to 
detect potential abuse of the compound and to more closely monitor AEs consistent with the known 
pharmacology for dasotraline will be implemented. 
An independent Data and Safety Monitoring Board (DSMB) will review safety data including data on 
adverse events (AEs) and serious adverse events (SAEs) at regular intervals. 
Subjects will self-administer study drug on an outpatient basis for 12 months, once a day at 
approximately the same time each morning with or without food, including on the days when clinic 
visits occur. Subjects meeting all inclusion and no exclusion criteria will start taking open-label study 
drug on Day 1, the morning following the OL Baseline visit (ie, Week 12 visit in the core study).  
The total daily dose will remain between 4 mg/day and 8 mg/day for the 12-month treatment period. 
Dasotraline will be dosed at 4 mg/day for the first 2 weeks of the study. At the Week 2 visit, the dose 
may be increased to 6 mg/day. Thereafter the dose may be increased or decreased by 2 mg/day, as 
necessary for effectiveness or tolerability reasons at the discretion of the investigator. A minimum of 
8 days is required between dose increases. Dose decreases may be made at less than 8 day intervals, at 
the investigator’s discretion, for reasons of safety or tolerability. If, in the judgment of the investigator, 
the subject does not tolerate the minimum required dose (4 mg/day), he or she will be discontinued 
from the study. 
All changes in study drug dose will begin the morning after the visit at which the dose change decision 
is made and using the new package of study drug. 
The study will consist of a baseline visit, 12-month open-label treatment period, and 3-week study drug 
withdrawal period as shown in the Study Schematic (Figure 1). During the treatment period, subjects 
will return to the clinic at the end of 2 and 4 weeks for clinical evaluation and thereafter will return to 
the clinic once every 4 weeks during the treatment period for scheduled visits. At the approximate 
midpoint between the scheduled monthly visits (ie, 14 ± 2 days after a visit), the site staff will contact 
the subject via telephone, text, or email in order to monitor for SAEs, AEs, and concomitant 
medications, as well as to remind subjects about adherence to study drug administration, and upcoming 
visits. If necessary, an unscheduled visit can be arranged.

Subjects will attend weekly visits during the 3-week study drug withdrawal period. Assessment of 
potential withdrawal effects will be conducted via administration of the CSSA, DESS, HAM-A, and 
MADRS at the end of treatment. Subjects will undergo assessments every other day and weekly as 
follows: the CSSA and DESS will be completed every other day during the 3-week study medication 
withdrawal period. Clinical site staff will call the subject every other day, beginning the second day 
after the last dose of study drug, unless a clinic visit is scheduled for that day. Phone contacts may be 
made up to 3 times per day if the clinical site staff is unable to contact the subject on the first 
2 attempts. If the subject cannot be contacted on a given day, during the next contact the study site staff 
will retrospectively collect the missed CSSA and DESS, in addition to the current day’s CSSA and 
DESS, as necessary. Clinical site staff will record the responses in the subject’s source information and 
in the CRF with the contact date and time. The CSSA, DESS, HAM-A, and MADRS also will be 
administered at each weekly visit during the withdrawal period. 
A window of ± 1 day will be allowed for each weekly clinic visit and telephone call during the study 
medication withdrawal period. 
After the last withdrawal period visit, all subjects will be referred for follow-up care as determined by 
the investigator. 
Number of Subjects (planned): This study is projected to enroll approximately 500 subjects based on 
the number of subjects expected to complete treatment in the core studies.

Subject-reported Health Status Endpoints: 
• 
Change in SF-12 two component scores (physical component, mental health component)2 
Statistical Methods: 
The safety population will include all subjects who receive at least one dose of study medication. A 
total of 2 analysis groups will be formed based on a subject’s previous participation in the core study 
(previously randomized to dasotraline, previously randomized to placebo). A group that combines 
these 2 analysis groups also will be presented. Summary tables, wherever applicable, will be presented 
by analysis group, respectively. Where changes are reported, the reference will be to the pretreatment 
baseline from the core study, and indicated as “DB baseline”. Where relevant, changes from baseline 
for the open-label study, defined as the Week 12 assessment in the double-blind study or the last 
assessment prior to the first dose of study medication in the open-label study, will also be reported, and 
will be referred to as the open-label study baseline or "OL baseline." Continuous variables will be 
summarized using descriptive statistics (N, mean, standard deviation, median, range, 95% confidence 
interval [CI] as needed) and categorical variables will be reported as frequencies and percentages. No 
statistical comparisons will be conducted and no inferential statistics on effectiveness and safety will be 
presented. 
Safety Analyses: The safety data will be analyzed by analysis group based on the safety population for 
the open-label treatment period (for data up to the end of treatment period) and withdrawal period (for 
data collected during the withdrawal period), separately, as appropriate. 
Treatment-emergent adverse event (TEAE) and discontinuation-emergent adverse events (DEAE) will 
be summarized (hereafter TEAE is referred as AE). The incidence of AEs, SAEs, and AEs leading to 
discontinuation due to AEs (or SAEs) will be summarized by analysis group (by presenting the number 
and percentage of subjects with one or more AEs in each category). The number and proportion of 
subjects with one or more AEs within a system organ class (SOC) or by preferred term will be 
presented by analysis group as well. 
For laboratory tests (hematology, chemistry, urinalysis, lipid panel, hemoglobin A1c), weight, BMI, 
vital signs, neurological examination, and ECG parameters, descriptive statistics will be provided for 
observed values and changes from DB baseline and OL baseline for the continuous variables. 
Frequencies and percentages will be reported for categorical variables by study visit and analysis 
group. The markedly abnormal values for selected safety parameters will be summarized, as 
appropriate. 
The number and percentage of subjects with suicidal ideation and/or suicidal behavior, emergence or 
worsening of suicidal ideation or suicidal behavior will be summarized by analysis group for the open-
label treatment period, and the withdrawal period, separately. 
The CSSA total score, DESS total score, MADRS total score, and HAM-A total score will be 
summarized by presenting descriptive statistics of observed values and changes from Week 52/EOT by 
treatment and visit for the withdrawal period. 
Analyses for Effectiveness and Subject-reported Health Status: Descriptive statistics of observed 
values and changes from DB baseline and OL baseline in BE-CGI-S score, EDE-Q modified  global 
and subscale scores (restraint, shape concern, weight concern), EDE-Q modified items 4-6 scores, SDS 
total score and subscale scores (school/work disability, social life disability, and family life disability), 
and SF-12 (subjects from Study SEP360-221) two component scores (physical component, mental

Abbreviations: BSN = baseline; EOS = End of Study; EOT = End of Treatment; OL = open label; V = visit  
a Week 12 in core study. Baseline assessments indicated as “carried over” are primarily performed as part of Week 12 visit in the core study and do not need to be repeated; the 
data will be duplicated from Week 12 visit or other visits (such as for height) in the core study.  
b Subjects who discontinue from the study prior to completion of treatment with study drug will be asked to return to the site and complete the EOT assessments within 1 day of 
discontinuation and complete the Withdrawal Period visits and calls. 
c Subjects will take the first dose of study drug in this study on Day 1 (the morning following the baseline visit); there will be no break in study drug treatment between the core 
study and this extension study. All study drug will be administered by the subject once a day at approximately the same time each morning including on the days when clinic 
visits occur. 
d At the approximate midpoint between the scheduled monthly treatment period visits (ie, 14 ± 2 days after a visit), the site staff will contact the subject via telephone, text, or 
email to monitor for SAEs, AEs, and concomitant medications, as well as to remind subjects about adherence to study drug administration and upcoming visits, following which 
an unscheduled visit may be scheduled, if necessary.

e Informed consent will be obtained from all subjects after all procedures from the core study have been completed and before any study procedures unique to this study are 
performed.  
f  Subjects must be fasting for at least 8 hours (may have water) prior to the indicated laboratory tests. Visits should be scheduled in the morning. 
g  The “Since Last Visit” version will be used. Subjects who answer “yes” to “suicidal ideation” item 4 (active suicidal ideation with some intent to act, without specific plan) or 
item 5 (active suicidal ideation with specific plan and intent) on the C-SSRS assessment at any time during the study must be referred to the Investigator for follow up 
evaluation. 
h The Structured Interview Guide for the HAM-A (SIGH-A) will be used for the administration of the HAM-A. 
i The Structured Interview Guide for the MADRS (SIGMA) will be used for the administration of the MADRS. 
j Clinical site staff will call the subject every other day (± 1 day) during the study medication withdrawal period, beginning the second day after the last dose of study drug (unless 
a clinic visit is scheduled for that day) in order to collect the Cocaine Selective Severity Assessment (CSSA) and Discontinuation-Emergent Signs and Symptoms (DESS). 
Clinical site staff may call up to 3 times per day if the clinical site staff are unable to contact the subject on the first 2 attempts. If the subject cannot be contacted on a given day, 
during the next contact the study site staff will retrospectively collect the CSSA and DESS from the missed day(s) and the current day, as necessary. 
k Any positive urine β-hCG test should be confirmed by serum β-hCG. 
l Carried over for subjects enrolling in this study from SEP360-321 and collected for subjects enrolling in this study from SEP360-221.

INTRODUCTION 
4.1. 
Background 
Binge eating disorder (BED) is a neuropsychiatric disorder characterized by recurrent episodes 
(on average at least once per week for 3 months) of excess food consumption during a limited 
time period, accompanied by feelings of loss of control and distress in the absence of regular 
compensatory behaviors characteristic of bulimia nervosa (BN) (Diagnostic and Statistical 
Manual of Mental Disorders, 5th Edition [DSM-5]). BED is the most common eating disorder in 
the United States and Western Europe, with an estimated lifetime prevalence of 2.5% in adults 
(~3.5 % in adult women, 2.0 % in adult men, and 1.6 % in adolescents) and a mean age of onset 
of 25.4 ± 1.2 years (McElroy-2012, Kessler-2013, Hudson-2007). Binge eating disorder is 
defined in DSM-5 as: 
• Recurrent episodes of binge eating characterized by both: 
− Eating an amount of food larger than what most people would eat, in a discrete 
period of time (eg, 2 hours) 
− Sense of lack of control over eating episode 
• Binge-eating episode associated with ≥ 3: 
− Eating much more rapidly than normal 
− Eating until uncomfortably full 
− Eating large amounts when not feeling hungry 
− Eating alone because of embarrassment 
− Feeling disgusted with oneself, guilty afterward 
• Marked distress regarding binge eating is present 
• Binge eating occurs, on average, at least once a week for 3 months 
• Not associated with recurrent use of compensatory behavior (eg, bulimia nervosa). 
Patients with BED show significantly higher prevalence or risk for a range of comorbid 
psychiatric and medical disorders when compared to healthy individuals. The majority of 
patients fulfill Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) 
criteria for one or more psychiatric disorders, including depression, anxiety, and phobias. BED 
patients also have a 2-3 fold greater risk for physical ailments, including obesity, hypertension, 
diabetes mellitus, and chronic pain. Taken together, these findings signify that BED presents a 
major public health problem with significant social and economic consequences (Kessler-2013). 
Considering the severity of clinical symptomology, the negative impact on quality of life and 
physical measures of health, there is a significant need for safe and efficacious treatments for 
adults with BED.

4.1.1. 
Neurobiology of Binge Eating Disorder 
Nonclinical and clinical studies have implicated dopamine, opioid, and norepinephrine systems 
within the brain reward circuit in the pathogenesis of eating and addictive disorders, including 
binge eating disorder (Murray-2014, Gold-2013, Smith-2013, Hoebel-1989). In particular, 
disturbances in dopamine and the dopamine D2/3 receptor play a key role in binge eating, 
suggesting that drugs targeting disturbances in dopaminergic transmission may be effective in 
treating the disorder. 
Nonclinical studies show that rats continue to self-administer substances that act like dopamine, 
or stimulate dopamine release, in response to a dysregulated reward circuit (Murray-2014, 
Ikemoto-1997, Carlezon-1995). Rats continuously fed a cafeteria diet or a high-fat, high sugar 
meal show reduced levels of dopamine and dopamine D2/3 receptors in the dorsal striatum and 
nucleus accumbens that form part of the reward circuit (van de Giessen-2012, 
van de Giessen-2013). Knockout of striatal dopamine D2 receptors induces compulsive-type 
behavior in response to highly palatable food (Johnson-2010). High-fat diets are associated with 
reduced dopamine transporter (DAT) expression and dopamine efflux (Speed-2011). In 
nonclinical studies of drug abuse, reduced availability of dopamine D2 receptors in the striatum 
lead to increased and habitual drug intake, further supporting the importance of this transmitter 
system in addictive behaviors, and suggesting that BED and other impulse control disorders 
share overlapping neural mechanisms (Trifilieff-2014, Smith-2013). 
Clinical, genetic, and neuroimaging studies of eating behaviors in humans have shown parallel 
disturbances in the brain reward circuit and dopamine transmission in patients with BED, 
including reduced availability of dopamine D2 receptors in the striatum (Murray-2014, 
Smith-2013). Down regulation of dopamine D2 receptors in response to overeating leads to a 
hyper-responsive reward system that is sensitized to food, perpetuating patterns of recurrent food 
craving and overconsumption that result in BED in susceptible individuals. Further evidence for 
a hyper-responsive reward circuit in BED patients comes from neuroimaging studies using 
positron emission tomography (PET). Administration of methylphenidate, an inhibitor of the 
dopamine reuptake transporter, results in greater increases in dopamine levels in the caudate 
nucleus in response to food in BED patients when compared to individuals without BED. These 
increases are significantly correlated with higher binge eating scores (Wang-2011). Additional 
PET studies have shown negative correlations between impulsivity and availability of dopamine 
D2/3 receptors in the striatum and midbrain of humans (Lee-2009, Buckholtz-2010). 
Similar to findings from the PET studies, functional magnetic resonance imaging (MRI) studies 
show a dysregulated and hyper-responsive reward circuit in response to food in BED patients. 
Exposure to high-calorie or highly palatable food stimuli elicits greater activation in reward 
areas, such as the nucleus accumbens and orbital frontal cortex in BED patients compared to 
controls, which directly correlates with the severity of binge-eating symptoms (Schienle-2009, 
Filbey-2012). Together these studies show that a dysregulated dopaminergic driven reward 
circuit is critical to the symptomology associated with BED and suggest that therapies targeting 
this system may be effective interventions for the disorder. 
4.1.2. 
Pharmacological Management of Binge Eating Disorder 
Although cognitive, behavioral and interpersonal psychotherapies improve binge eating 
symptoms, many patients do not respond. Recent studies suggest that pharmacotherapies that

Dasotraline 
 
 
Confidential and Proprietary 
29 
13 Jun 2017 
 
target one or more of the neurotransmitter systems implicated in BED may play a critical role in 
its management (McElroy-2012). 
Several classes of pharmacological agents have been evaluated in randomized, double-blind, 
placebo-controlled or open-label studies, including selective serotonin reuptake inhibitors 
(SSRIs), antiobesity agents, anticonvulsants, and stimulants (Hudson-1998, McElroy-2000, 
Arnold-2002, McElroy-2003A, Stunkard-1996, Appolinario-2003, Grilo-2005, McElroy-2003B, 
McElroy-2006, McElroy-2007, Leombruni-2006, NCT01718483, NCT01718509). 
Lisdexamfetamine dimesylate is a central nervous stimulant indicated for the treatment of attention 
deficit hyperactivity disorder (ADHD). In two 12–week, randomized, placebo-controlled 
registration studies, lisdexamfetamine dimesylate showed significant reductions in binge eating 
frequency (NCT01718483, NCT01718509) and these efficacy results supported United States 
Food and Drug Administration (FDA) approval of Vyvanse® as a treatment for adults with BED 
(Shire-2015). 
4.2. 
Study Conduct Rationale 
Dasotraline (also known as SEP-225289), a new chemical entity currently in clinical trials for 
ADHD, blocks pre-synaptic DAT and norepinephrine transporter (NET). Unlike 
psychostimulants such as amphetamine, which facilitate the direct release of dopamine and 
norepinephrine (Hutson-2014, Minzenberg-2012), dasotraline is a dual dopamine and 
norepinephrine reuptake inhibitor (DNRI). Dasotraline has a long time to maximum 
concentration (tmax; reaches maximum concentrations approximately 10 to 12 hours after dosing) 
and mean apparent half-life (47.1 to 77.0 hours). 
A nonclinical study was conducted to compare the acute effects of dasotraline in a rat model of 
BED with lisdexamfetamine dimesylate, and its pharmacologically active metabolite, 
d-amphetamine. Rats that were allowed irregular and limited access to chocolate developed 
robust and intermittent hyperphagia that mirrored BED without associated obesity. Binge eating 
of chocolate was markedly reduced by a single oral dose of dasotraline. The reduction in 
chocolate consumption was dose dependent and comparable to the effects observed with both 
lisdexamfetamine dimesylate and d-amphetamine in this rat BED model. 
A recently completed clinical study supports dasotraline as a potentially safe and efficacious 
treatment option for adults with ADHD (Koblan-2015). Clinically meaningful and statistically 
significant treatment effects were observed at 8 mg/day. Consistent with DNRI pharmacology, 
the most frequent adverse events reported in the study were insomnia, decreased appetite, and 
dry mouth. In addition, significant dose dependent decreases were observed in appetite and 
weight loss. A review of previously published trials for BED suggests that decreases in appetite 
and weight loss are strongly associated with a reduction in binge eating frequency 
(Appolinario-2003, Grilo-2005, McElroy-2003B, McElroy-2006, McElroy-2007, 
McElroy-2012). Administration in over 1000 adult subjects in completed and ongoing studies 
supports the safety of dasotraline for continued evaluation. 
Use of dasotraline as a potential treatment for BED is supported by research that suggests 
pharmacotherapies that target one or more of the neurotransmitter systems (including dopamine 
and norepinephrine) that have been implicated in the pathogenesis of BED may play a critical 
role in its management. The centrally acting effects of dasotraline on dopamine and

norepinephrine uptake combined with the results from the SEP360-201study, and the rat model 
study of binge eating provide further support to evaluate dasotraline as a treatment for BED. 
The initial 12-week study SEP360-221 evaluates dasotraline flexibly dosed at 4, 6, or 8 mg/day 
and the 12-week study SEP360-321 evaluates dasotraline fixed doses of 4 or 6 mg/day as a 
potential treatment for BED. The current study evaluates long term safety and efficacy of 
dasotraline as a treatment for BED and will enroll subjects who complete treatment in Study 
SEP360-221 or Study SEP360-321. 
4.3. 
Risk-Benefit Assessment 
Overall, in previous clinical studies dasotraline was generally safe and well tolerated. The 
pharmacokinetic (PK) and safety profiles observed in adults from completed clinical studies 
support evaluation of dose levels of 4 – 8 mg/day in adults with BED. 
Most adverse events in completed clinical studies were mild to moderate in intensity, and 
included headache, dizziness, insomnia, tachycardia, and nausea. Dose dependent increases in 
the incidence of insomnia and weight loss were observed, consistent with DNRI pharmacology. 
A total of 13 serious adverse events (SAEs) have been reported in 9 subjects receiving 
dasotraline. Across the 8 completed clinical studies evaluating dasotraline, the rate of 
discontinuations as a result of treatment-emergent adverse events (TEAEs) was low. The highest 
rate of discontinuations due to TEAEs was in the SEP360-201 adult ADHD study (11.2% and 
29.7% of subjects treated with dasotraline 4 and 8 mg/day, respectively), primarily due to 
insomnia. In general, the side-effect profile of dasotraline, based on available data, appears 
comparable with other medications used in the treatment of ADHD and suggests it may be well 
tolerated in patients with BED. A flexible dose design to reach the 8 mg dose will be 
implemented in this study to facilitate management of safety and tolerability issues. 
The results from the human abuse liability study indicate dasotraline has minimal abuse potential 
and is unlikely to be recreationally abused. All doses of dasotraline (8, 16, 36 mg) demonstrated 
significantly lower drug liking scores than methylphenidate (40, 80 mg) and were no greater than 
placebo. The most frequently reported abuse potential adverse events were insomnia and 
dizziness in subjects with major depressive disorder (MDD) and insomnia and suicidal ideation 
in adults with ADHD. The current study will be conducted in accordance with relevant 
regulatory guidance and law with regards to handling, distribution, storage, dispensation, 
accountability, and destruction of study drug. In addition a comprehensive Abuse Potential 
Monitoring Plan (APMP) for dasotraline designed to detect potential abuse of the compound and 
to more closely monitor adverse events (AEs) consistent with the pharmacology of the 
compound will be implemented for this study (Section 24, Appendix V). 
Additionally, a Data and Safety Monitoring Board (DSMB) will be established for this study. 
The DSMB will review safety data including AEs and SAEs at regular intervals. 
Results from the adult ADHD study and the rat model of binge-eating combined with 
dasotraline’s DNRI pharmacology, and extended PK profile suggest dasotraline may prove safe 
and efficacious in the treatment of patients with BED. Although drugs targeting disturbances in 
dopaminergic transmission may translate to therapeutic benefit in BED, the efficacy and safety 
of dasotraline in this indication is currently being evaluated.

INVESTIGATIONAL PLAN 
7.1. 
Overall Study Design 
This is a Phase 3, 12-month, multicenter, open-label, flexibly-dosed, safety study in adults with 
BED. This study is projected to enroll approximately 500 subjects based on the number of 
subjects expected to complete treatment in the core studies (ie, SEP360-221 or SEP360-321). 
Informed consent will be obtained from all subjects after all procedures from the core study have 
been completed and before any study procedures unique to this study are performed. Safety and 
tolerability will be monitored throughout the study by AE reports, physical and neurological 
examinations, 12-lead ECG, vital signs, body weight, BMI, clinical laboratories (hematology, 
chemistry, urinalysis, hemoglobin A1c, and lipid panel), and C-SSRS. Effectiveness will be 
evaluated using the BE-CGI-S, EDE-Q modified, and SDS. Subject-reported health status will be 
assessed using the SF-12 (subjects from Study SEP360-221 only). Assessment of potential 
withdrawal effects of dasotraline will be conducted via administration of the CSSA, DESS, 
HAM-A, and MADRS at the end of treatment and during the 3-week study medication 
withdrawal period. 
A comprehensive Abuse Potential Monitoring Plan (APMP; see Section 24) for dasotraline 
designed to detect potential abuse of the compound and to more closely monitor AEs consistent 
with the known pharmacology for dasotraline will be implemented. 
An independent Data and Safety Monitoring Board (DSMB) will review safety data including 
data on adverse events (AEs) and serious adverse events (SAEs) at regular intervals. 
Subjects will self-administer study drug on an outpatient basis for 12 months, once a day at 
approximately the same time each morning with or without food, including on the days when 
clinic visits occur. Subjects meeting all inclusion and no exclusion criteria will start taking 
open-label study drug on Day 1, the morning following the open-label (OL) Baseline visit (ie, 
Week 12 visit in the core study). 
The total daily dose will remain between 4 mg/day and 8 mg/day for the 12-month treatment 
period. Dasotraline will be dosed at 4 mg/day for the first 2 weeks of the study. At the Week 2 
visit, the dose may be increased to 6 mg/day. Thereafter the dose may be increased or decreased 
by 2 mg/day, as necessary for effectiveness or tolerability reasons at the discretion of the 
investigator. A minimum of 8 days is required between dose increases. Dose decreases may be 
made at less than 8 day intervals, at the investigator’s discretion, for reasons of safety or 
tolerability. If, in the judgment of the investigator, the subject does not tolerate the minimum 
required dose (4 mg/day), he or she will be discontinued from the study. 
All changes in study drug dose will begin the morning after the visit at which the dose change 
decision is made and using the new package of study drug. 
The study will consist of a baseline visit, 12-month open-label treatment period, and 3-week 
study drug withdrawal period as shown in the Study Schematic (Figure 1). During the treatment 
period, subjects will return to the clinic at the end of 2 and 4 weeks for clinical evaluation and 
thereafter will return to the clinic once every 4 weeks during the treatment period for scheduled 
visits. At the approximate midpoint between the scheduled monthly visits (ie, 14 ± 2 days after a

visit), the site staff will contact the subject via telephone, text, or email in order to monitor for 
SAEs, AEs, and concomitant medications, as well as to remind subjects about adherence to study 
drug administration, and upcoming visits. If necessary, an unscheduled visit can be arranged. 
Subjects will attend weekly visits during the 3-week study drug withdrawal period. Assessment 
of potential withdrawal effects of dasotraline will be conducted via administration of the CSSA, 
DESS, HAM-A, and MADRS at the end of treatment. Subjects will undergo assessments every 
other day and weekly as follows: The CSSA and DESS will be completed every other day during 
the 3-week study medication withdrawal period. Clinical site staff will call the subject every 
other day, beginning the second day after the last dose of study drug, unless a clinic visit is 
scheduled for that day. Phone contacts may be made up to 3 times per day if the clinical site staff 
are unable to contact the subject on the first 2 attempts. If the subject cannot be contacted on a 
given day, during the next contact the study site staff will retrospectively collect the missed 
CSSA and DESS, in addition to the current day’s CSSA and DESS, as necessary. Clinical site 
staff will record the responses in the subject’s source information and in the case report form 
(CRF) with the contact date and time. The CSSA, DESS, HAM-A, and MADRS also will be 
administered at each weekly visit during the withdrawal period. 
A window of ± 1 day will be allowed for each weekly clinic visit and telephone call during the 
study medication withdrawal period. 
After the last withdrawal period visit, all subjects will be referred for follow-up care as 
determined by the investigator. 
A study schematic is presented in Figure 1. Details of the study assessments and other 
procedures to be performed at each visit are presented in Table 2, Schedule of Assessments, and 
Section 11, Study Assessments. 
If necessary, subjects may return to the clinic at any time for an unscheduled visit.

Rationale 
7.3.1. 
Rationale for the Study Design 
This is an open-label study to evaluate the long-term safety and effectiveness of flexibly-dosed 
dasotraline consistent with the intended long-term use of the compound in this population. 
7.3.2. 
Rationale for the Dosages 
The dosages to be used in this study (4, 6, or 8 mg/day) are the same as those administered in the 
core study SEP360-221. Doses of 4 and 6 mg are administered in the core study SEP360-321. 
7.3.3. 
Rationale for the Study Population 
Subjects in this study will have met BED eligibility requirements in the core study and not have 
taken any medication other than study drug for the purpose of controlling BED symptoms during 
the core study. 
7.3.4. 
Rationale for the Endpoints 
The safety assessments and their timing are considered appropriate to assess the long-term safety 
of dasotraline, taking into account known pharmacology and adverse events based on previous 
studies. The symptom, functional, and quality of life assessments were selected to assess the 
potential effectiveness of dasotraline on these parameters. 
7.3.5. 
Prevention of Missing Data 
In an effort to minimize the number of subjects who are terminated from the study before study 
completion, the following study design and conduct elements are implemented: (i) clinic visits 
every 2 weeks for the first month, every 4 weeks for the remainder of treatment, and every week 
during the study drug withdrawal period, (ii) during the treatment period a window of ± 3 days 
for each bi-weekly or monthly clinic visit and a window of ± 1 day for each weekly clinic visit 
starting at Week 52, (iii) training the sites on the importance of continued follow-up and on the 
informed consent process, ensuring subjects understand the commitment they are making,

Study Drug Storage 
All study medication should be stored at United States Pharmacopeia (USP) Controlled Room 
Temperature: 20°C to 25°C (68°F - 77°F); excursions permitted to 15°C to 30°C (59°F - 86°F) 
but must still be reported to CRO. The subject will be instructed to store the study medication at 
room temperature. 
9.4. 
Dispensing of Study Drug  
An Interactive Response System (IXRS) will be used to manage subject enrollment. The IXRS is 
an integrated web-based subject and drug management system. 
Study drug blister cards will be assigned by the IXRS based on the treatment schedule and dose 
adjustment criteria. The IXRS will generate instructions on which medication number to assign 
to a subject. Each subject will be dispensed two or four 10-day blister cards per scheduled visit 
depending on the timing of the next scheduled visit (see Table 2). 
Subjects will self-administer the study drug on an outpatient basis. 
9.5. 
Study Drug Accountability 
The Investigator or designee is responsible for storing the study drug in a secure location and for 
maintaining adequate records of drug disposition that includes the dates, quantity, and use by 
subjects. If the study is stopped for any reason or completed, all unused supplies of drug will be 
returned to the Sponsor, unless other instructions are provided in writing by Sponsor/ clinical 
research organization (CRO). 
Upon receipt of clinical trial material (CTM), the Investigator or designee will inventory the 
supplies and verify receipt of supplies. The site will send an Acknowledgement of Receipt to 
Sunovion Pharmaceuticals, or designee, confirming date of receipt, inventory, and condition of 
CTM received. 
The Investigator or designee on an ongoing basis must maintain a study drug inventory record of 
supplied, received, dispensed, and returned study drug for use as the primary source for study 
drug accountability. 
9.6. 
Study Drug Handling and Disposal 
On an ongoing basis, the Investigator or designee must maintain a study medication inventory 
record of supplied, received, dispensed, and returned medication. 
The study medication will not be dispensed to any person who is not a study subject under this 
protocol. 
The Investigator or designee is required to return all used and unused study medication to the 
Sponsor or designee as instructed. The Investigator or designee is required to maintain copies of 
medication shipping receipts, study medication accountability records, and records of return of 
the study medication.

TREATMENT OF SUBJECTS 
10.1. 
Study Medication 
10.1.1. 
Dose or Dosage for Study Drug 
Dasotraline 4 mg, 6 mg, or 8 mg capsules for oral administration will be supplied for the study as 
described in Section 9. 
Subjects will self-administer the study drug on an outpatient basis once a day beginning on 
Day 1, the day after the Baseline visit, and continue for 12 months. Subjects will be instructed to 
administer study drug at approximately the same time each morning including on days when 
clinic visits occur. If an individual subject requires a change to time of dosing (eg, evening shift 
worker), this must be approved by the Medical Monitor, and the subject should take the study drug at 
the same time of day throughout the study. All doses of study drug will consist of 1 capsule taken 
orally. 
Subjects may take study medication with or without food. 
10.1.2. 
Dose Adjustment Criteria 
The total daily dose will remain between 4 mg/day and 8 mg/day for the 12-month treatment 
period. Dasotraline will be dosed at 4 mg/day for the first 2 weeks of the study. At the Week 2 
visit, the dose may be increased to 6 mg/day. Thereafter the dose may be increased or decreased 
by 2 mg/day, as necessary for effectiveness or tolerability reasons at the discretion of the 
investigator. A minimum of 8 days is required between dose increases. Dose decreases may be 
made at less than 8 day intervals, at the investigator’s discretion, for reasons of safety or 
tolerability. If, in the judgment of the investigator, the subject does not tolerate the minimum 
required dose (4 mg/day), he or she will be discontinued from the study. 
All changes in study drug dose will begin the morning after the visit at which the dose change 
decision is made and using the new package of study drug. 
10.2. 
Treatment Compliance 
Compliance with study drug will be monitored closely and determined at each visit during 
treatment. Subjects will be instructed to bring all unused study drug with them to each visit. 
Compliance will be assessed by counting capsules and dividing the actual number of doses taken 
(per capsule count) by the number of doses the subject should have taken within a visit period 
and multiplying by 100. Subjects who miss more than 25% of scheduled doses or take more than 
125% of the scheduled doses will be considered noncompliant. Evidence of noncompliance must 
be immediately reported to the Medical Monitor. Potential noncompliance will be discussed with 
subject, and at the investigator’s discretion may result in termination of the subject from the 
study. All subjects will be reminded of the importance of strict compliance with taking study 
drug for the effectiveness of treatment and for the successful outcome of the study.

− Use of any other sleep aids should be approved by the Medical Monitor 
• Medications used for the treatment of anxiety/agitation and insomnia (eg, lorazepam 
and zolpidem) should not be used in close temporal proximity (defined as 
administration within 2 hours of each other) 
• Opiates may be allowed in rare cases for a limited period of time with prior 
authorization from the Medical Monitor 
• Medications for short-term treatment of a medical condition (no more than 10 days) 
are allowed following consultation with the Medical Monitor 
• Subjects who require treatment with more than 1 of the restricted concomitant 
medications (including other antipsychotics or anxiolytics [lorazepam or equivalent 
above protocol-specified limits]) will be discontinued (as appropriate) from the study 
• Contraceptives (see Section 22, Appendix III) 
The date and time of the last dose taken prior to scheduled effectiveness assessments of any sleep 
aid listed above must be recorded at each visit.  
10.3.4. 
Permitted Therapies 
Participation in non-pharmacologic therapy, such as supportive psychotherapy, cognitive 
behavioral therapy or interpersonal therapy is permitted and should be documented by the 
investigator, to the extent possible. 
10.3.5. 
Contraception Requirements 
Female subject of childbearing potential and male subject with female partner of childbearing 
potential must agree to use an effective and medically acceptable form of birth control, as

described in Section 22, Appendix III, from informed consent through the end of the study. Note: 
Continued use of an effective and medically acceptable form of birth control is recommended for 
30 days after study completion or premature discontinuation from the study. 
10.4. 
Guidance for Overdose 
There is no overdose experience with dasotraline in humans. Signs and symptoms of overdose in 
nonclinical studies were consistent with exaggerated pharmacology and included hyperactivity, 
stereotypy, aggressiveness, and reduced food intake and body weight loss. 
Activated charcoal may be of value if administered very soon after a dasotraline overdose (ie, 
during the absorption process). 
10.5. 
Cautions 
Dasotraline capsules should not be opened or tampered with in any way; the active ingredient is 
an ocular irritant.

Safety Assessments 
11.2.1. 
Adverse Events 
Adverse events will be collected for each subject. Subjects should be queried in a non-leading 
manner, without specific prompting (eg, “Has there been any change in your health status since 
your last visit?”). See Section 12, Safety Reporting. 
AEs will be monitored throughout the study at all visits including telephone, text, or email 
assessments. 
Information on AEs carried over from the core-study will be described in the DMP. 
11.2.2. 
Clinical Laboratory Tests 
The clinical laboratory tests required by protocol are listed in Section 21, Appendix II. 
Blood and urine samples will be collected for clinical laboratory tests. All clinical laboratory 
tests will be performed centrally. For detailed instructions regarding clinical laboratory 
procedures, sampling, and shipping guidelines refer to the Central Laboratory Instructions 
Manual. Samples will be processed at a central laboratory to ensure consistency. All clinical 
laboratories will be College of American Pathologists (CAP) and Clinical Laboratory 
Improvement Amendments (CLIA) (or equivalent) certified. 
Any POC (point of care) kits that are performed on site by study personnel rather than in a lab- 
must be CLIA waived and the study center must possess a CLIA certificate of Waiver. 
11.2.3. 
Vital Signs 
Following 5 minutes of rest, respiration rate, oral temperature, and supine systolic and diastolic 
blood pressures and pulse rate will be measured. Systolic and diastolic blood pressures and pulse 
rate will be taken again with the subject standing after the subject has been standing for 2 to 
4 minutes. The same arm should be used during each assessment of blood pressure and pulse rate 
throughout the study. If a subject develops symptoms consistent with orthostatic hypotension 
(light-headedness, dizziness, or changes in sensorium upon standing) at any point, his or her 
supine and standing blood pressure and pulse rate should be collected at that time in the manner 
described above. Vital signs will be obtained prior to clinical laboratory sample collection and 
performance of an ECG, whenever possible. 
11.2.4. 
Electrocardiograms (ECGs) 
All ECGs will be obtained in the supine position, after the subject has been resting supine for at 
least 10 minutes. ECGs will be 12-lead with a 10-second rhythm strip. ECGs should be obtained 
before drawing blood samples. All attempts should be made to use the same ECG recorder for all 
visits within individual subjects. ECGs will be centrally read by a centralized cardiac safety 
vendor according to established quality additional information assurance procedures for 
inter/intra reader variability. Refer to Section 20 (Appendix I) for additional information. 
Standard 12-lead ECG will record heart rate (HR), PR interval, RR interval, QT interval, QTc 
interval, and QRS duration.

Physical and Neurological Examinations 
Clinically significant physical and neurological examination findings, as judged by the 
investigator, after baseline (carried over) will be recorded as AEs. 
The physical examination will consist of an assessment of body systems including but not 
limited to head, ears, eyes, nose and throat (HEENT), cardiovascular (heart and vascular system), 
respiratory (lungs and chest), gastrointestinal (abdomen), and skin. 
Neurological examinations will include a brief assessment of mental status, cranial nerves, motor 
strength and coordination, sensory function in addition to deep tendon reflexes. 
11.2.6. 
Safety Scales 
11.2.6.1. Columbia Suicide Severity Rating Scale (C-SSRS) 
The C-SSRS (Posner-2007) is a tool designed to systematically assess and track suicidal AEs 
(suicidal behavior and suicidal ideation) throughout the study. The strength of this suicide 
classification system is in its ability to comprehensively identify suicidal events while limiting 
the over-identification of suicidal behavior. The scale takes approximately 5 minutes to 
administer. The C-SSRS will be administered by a trained rater at the site. 
This study will utilize the “Since Last Visit” version of the C-SSRS. 
Subjects who answer “yes” to “suicidal ideation” item 4 (active suicidal ideation with some 
intent to act, without specific plan) or item 5 (active suicidal ideation with specific plan and 
intent) on the C-SSRS assessment at any time during the study must be referred to the 
Investigator for follow-up evaluation. 
11.2.6.2. Cocaine Selective Severity Assessment (CSSA) 
The CSSA (Kampman-1998) is a clinician-administered scale designed to evaluate withdrawal 
signs and symptoms related to stimulants over the past 24 hours. It takes approximately 
10 minutes to administer the 18-item scale. 
Included in the CSSA are those symptoms most often associated with early cocaine abstinence, 
including change in appetite, depression, fatigue, anhedonia, anxiety, irritability, sleep 
disturbance, and inability to concentrate, paranoia, carbohydrate craving, bradycardia, and 
suicidality. The CSSA is scored as follows: cocaine craving scores are obtained by having 
subjects record the highest intensity and frequency of cocaine craving experienced during the 
preceding 24 hours using visual analog scales. All items except item 14, are scored 0 to 7 
according to instructions on the CSSA generally with 0 = no symptoms and 7 = maximum score 
on any individual item. Item 14 is scored 0 to 8 with 0 = no symptoms and 8 = maximum score. 
Heart rate is determined by radial pulse measurement.  
On non-clinic days, the CSSA will be completed by site staff during a call to the subject. 
In order to complete the visual analog scale (VAS) portion of the CSSA on days when there are 
no scheduled clinic visits, subjects will be provided with copies of the VAS in advance, and will 
record their response at the time of scale administration.

In order to complete the radial pulse portion of the CSSA on days when there are no scheduled 
clinic visits, subjects will measure their own radial pulse and provide the measurement to the site 
staff over the phone. 
For consistency of radial pulse measurements, subjects also will take their own radial pulse for 
the CSSA completed during in-clinic visits. 
Subjects will be instructed by the site staff regarding the appropriate way to take their pulse. 
11.2.6.3. Discontinuation-Emergent Signs and Symptoms (DESS) Scale 
The DESS Scale (Rosenbaum-1998) is a clinician-rated instrument of 43 items used to evaluate 
signs and symptoms associated with discontinuation or interruption of monoamine reuptake 
inhibitor treatment. 
On non-clinic days, the DESS Scale will be completed by site staff during a call to the subject. 
11.2.6.4. Hamilton Anxiety Rating Scale (HAM-A) 
The HAM-A is a widely used and well-validated tool for measuring the severity of a patient’s 
anxiety. It should be administered by an experienced clinician. The HAM-A consists of 14 items, 
each defined by a series of symptoms, and measures both psychic anxiety (mental agitation and 
psychological distress) and somatic anxiety (physical complaints related to anxiety). Each item is 
scored on a 5-point scale, ranging from 0 = not present to 4 = severe. 
The Structured Interview Guide for the HAM-A (SIGH-A) will be used for the administration of 
the HAM-A. 
11.2.6.5. Montgomery-Asberg Depression Rating Scale (MADRS) 
The Montgomery-Asberg Depression Rating Scale (MADRS) is a widely used clinician-rated 
assessment of the subject’s level of depression. The measure contains 10 items that measure 
apparent and reported sadness, inner tension, reduced sleep and appetite, difficulty concentrating, 
lassitude, inability to feel, and pessimistic and suicidal thoughts. Each item is scored in a range 
of 0 to 6 points, with higher scores indicating increased depressive symptoms. 
The Structured Interview Guide for the MADRS (SIGMA) will be used for the administration of 
the MADRS. 
11.3. 
Effectiveness Assessments 
11.3.1. 
Eating Disorder Examination Questionnaire (EDE-Q) Modified 
The Eating Disorder Examination Questionnaire (EDE-Q) is a self-report version of the eating 
disorder examination (EDE) (Fairburn-1994). Like the EDE, the EDE-Q measures eating-
disorder psychopathology in the past 28 days, and over longer intervals for diagnostic items. The 
EDE-Q yields scores on the same subscales (dietary restraint, eating concern, weight concern, 
and shape concern), global score, and binge-eating frequency variables as the EDE interview. 
Research with clinical samples of patients with BED has reported acceptable agreement between 
the EDE-Q and EDE interview (Grilo-2001A; Grilo-2001B).

Convergent findings from confirmatory factor analyses of item data obtained from patients with 
BED (Grilo-2010) and patients with overweight/obesity (Grilo-2012; Grilo-2013; 
Hrabosky-2008) as well as non-clinical groups (Grilo-2015) support an alternative, brief version 
of the EDE-Q and EDE comprising 7 items to generate a global score and 3 subscales (dietary 
restraint, shape/weight overvaluation, and body dissatisfaction) referred to as the EDE-Q7 
(Grilo-2015). In the present study, the EDE-Q7 along with 3 items to assess binge eating, 
including the number of binge eating days will be used and referred to as the EDE-Q modified.  
11.3.2. 
Sheehan Disability Scale (SDS) 
The SDS was developed to assess functional impairment in 3 domains: work/school, social, and 
family life. The subject rates the extent to which work/school, social life, and home life have 
been impaired by his/her symptoms on an 11-point visual analog scale. The 3 items can be 
summed into a single global measure of impairment that ranges from 0 (unimpaired) to 
30 (highly impaired). This anchored visual analog scale uses spatiovisual, numeric, and verbal 
descriptive anchors simultaneously to assess disability across 3 domains: work; social life, and 
family life. There are verbal descriptors for the points on the scale as well as numerical scores 
that provide more precise levels of the verbal descriptors. The SDS takes approximately 
10 minutes to complete. 
11.3.3. 
Binge-eating Clinical Global Impressions–Severity of Illness (BE-CGI-S) 
The BE-CGI-S (Busner & McElroy, 2012; based on Guy-1976) asks the clinician one question: 
“Considering your total clinical experience with the adult Binge Eating Disorder (BED) 
population, how mentally ill is the subject at this time?” The clinician’s answer is rated on the 
following 7-point scale: 1 = normal, not at all ill; 2 = borderline mentally ill; 3 = mildly ill; 
4 = moderately ill; 5 = markedly ill; 6 = severely ill; 7 = among the most extremely ill subjects. 
This rating is based upon observed and reported BED symptoms, behavior, and function in the 
past 7 days. Clearly, symptoms and behavior can fluctuate over a week; the score should reflect 
the average severity level across the 7 days.

Other Assessments and Scales 
11.4.1. 
Short Form-12 Health Survey (SF-12) 
The SF-12 is a 12-item self-report questionnaire that is a subset of the SF-36 Health Survey. The 
survey captures physical and mental health. There are 8 subscales including: Physical 
functioning, Role-physical, Bodily pain, General health, Vitality, Social Functioning, 
Role-emotional, Mental health. The responses are reported on a 3 or 5 point Likert scale, 
depending on the question. The SF-12 is collected only for subjects enrolling in this study after 
completing Study SEP360-221.

SAFETY REPORTING 
12.1. 
Definitions 
12.1.1. 
Adverse Events 
An AE is any untoward medical occurrence in a study subject administered a medicinal 
(investigational) product and which does not necessarily have a causal relationship with this 
treatment. 
An AE can, therefore, be any unfavorable and unintended sign (including an abnormal laboratory 
finding), symptom, or disease occurring after the administration of a medicinal (investigational) 
product, whether or not considered related to the medicinal (investigational) product. AEs may 
include the onset of new illness and the exacerbation of pre-existing conditions. AEs will be 
collected from the time the informed consent is obtained to the last study visit. 
Lack of effectiveness may be an expected potential outcome and should not be reported as an AE 
unless the event is unusual in some way. 
New signs and symptoms of underlying disease, or signs and symptoms of emerging disease 
must be recorded as AEs. 
The Investigator should attempt to establish a diagnosis of the event based on signs, symptoms, 
and/or other clinical information. In such cases, the diagnosis should be documented as the AE 
and not the individual signs/symptoms. 
12.1.2. 
Serious Adverse Events 
A serious adverse event (SAE) is an AE that meets one or more of the following criteria:  
• Results in death 
• Is life-threatening (ie, a patient is at immediate risk of death at the time of the event, 
not an event where occurrence in a more severe form might have caused death) 
• Requires hospitalization or prolongation of existing hospitalization 
• Results in persistent or significant disability or incapacity 
• Is a congenital anomaly or birth defect 
• Is an important medical event that may jeopardize the subject or may require an 
medical or surgical intervention to prevent one of the outcomes listed above. 
Examples of such medical events include allergic bronchospasm requiring intensive 
treatment in an emergency room or at home, blood dyscrasias or convulsions that do 
not result in inpatient hospitalization 
The term "severe" is often used to describe the severity of a specific event (as in mild, moderate, 
or severe myocardial infarction) (see Section 12.3); the event itself, however, may be of 
relatively minor medical significance (such as severe headache). This is not the same as 


Protocol Study No. SEP360-322, Version 4.00  
Dasotraline 
 
 
Confidential and Proprietary 
55 
13 Jun 2017 
 
"serious," which is based on subject/event outcome or action criteria usually associated with 
events that pose a threat to a subject's life or functioning as defined by the criteria above. 
During the study, if a subject has a hospitalization or procedure (eg, elective surgery) that was 
scheduled before the study entry, ie, before informed consent for an event/condition that 
occurred before the study, the hospitalization is considered a therapeutic intervention and not the 
result of a SAE. However, if the event/condition worsens during the study, it should be reported 
as an AE (or SAE, if the event/condition results in a serious outcome such as prolongation of 
hospitalization). 
Life-threatening means that the subject was, in the view of the Investigator, at immediate risk of 
death from the event as it occurred. This definition does not include an event that had it occurred 
in a more severe form might have caused death. 
12.2. 
Objective Findings 
Clinically significant abnormal objective findings (eg, clinical laboratory value, ECG value, and 
physical examination observation) will also be recorded as AEs. 
When a clear diagnosis is available that explains the objective findings, this diagnosis will be 
recorded as the AE, and not the abnormal objective finding (eg, viral hepatitis will be recorded as 
the AE, not transaminase elevation). If a definite diagnosis is not available, then record the sign 
(eg, clinically significant elevation of transaminase levels) or symptom (eg, abdominal pain) as 
the AE. 
Clinical laboratory test results will be reviewed by the Investigator. The Investigator must 
determine the clinical significance of all out of range values. Clinical laboratory test with 
possibly drug-related or clinically relevant abnormal values of uncertain causality may be 
repeated. Any abnormal values that persist should be followed at the discretion of the 
Investigator. Laboratory reports will be initialed and dated on all pages by the Investigator. 
Clinical Laboratory Tests Outside the Normal Range: Any value outside the normal range will be 
flagged for the attention of the Investigator or appropriate designee at the site. The Investigator 
or appropriate designee will indicate whether or not the value is of clinical significance. If the 
result of any test (or repeat test, if done) from the samples taken at OL Baseline is indicated as 
clinically significant and is not covered by the inclusion criteria in Section 8.1, the subject will 
not be allowed into the study. Additional testing during the study may be done if medically 
indicated. If a clinically significant abnormality is found in the samples taken after dosing, 
during the study, and/or at the Follow-up Visit, this should be recorded as an AE and the subject 
will be followed until the test(s) has (have) normalized or stabilized. 
All on site ECG tracings and ECG over-read reports will be reviewed by the Investigator. The 
Investigator must determine the clinical significance of all abnormal ECGs. ECG with possibly 
drug-related or clinically relevant abnormal findings of uncertain causality may be repeated. Any 
abnormal ECG that persists should be followed at the discretion of the Investigator. ECG 
tracings will be initialed and dated on all pages by the Investigator.

12.3. 
Collection and Recording of Adverse Events 
All AEs must be collected and recorded in the subject’s study records/source documents, in 
accordance with the Investigator’s normal clinical practice, and on the CRF. All AEs will be 
followed up until resolution, stabilization of the condition, the event is otherwise explained, or 
the subject is lost to follow-up. 
Each AE is to be evaluated for duration, severity, frequency, seriousness, action taken with the 
study treatment, outcome, and causal relationship to the study treatment. Definitions for severity, 
frequency, action taken with the study treatment, outcome, and causal relationship to the study 
treatment are presented below. 
The severity of AE: 
• Mild - Ordinarily transient symptoms that do not influence performance of subject’s 
daily activities. Other treatment is not ordinarily indicated. 
• Moderate - Marked symptoms sufficient to make the subject uncomfortable. 
Moderate influence on performance of subject’s daily activities. Other treatment may 
be necessary. 
• Severe - Symptoms cause considerable discomfort. Substantial influence on subject’s 
daily activities. May be unable to continue the study, and other treatment may be 
necessary. 
The frequency of AE: 
• Once – an isolated episode 
• Intermittent – occurs on 2 or more separate occasions 
• Continuous – does not abate from date of onset to date of resolution 
The action taken with the study treatment: 
• Drug Interrupted – Study medication stopped temporarily 
• Drug Withdrawn – Study medication stopped permanently 
• Dose Reduced 
• Dose Increased 
• Dose not Changed 
• Not Applicable 
The outcome of the AE: 
• Recovered/Resolved 
• Recovering/Resolving 
• Not Recovered/Not Resolved 
• Recovered/Resolved with Sequelae 
• Fatal 


Protocol Study No. SEP360-322, Version 4.00

Confidential and Proprietary 
57 
13 Jun 2017 
 
• Unknown 
The causal relationship of the AE to the study treatment: 
• Not related  
o  Not related - Improbable temporal relationship and is plausibly related to 
other drugs or underlying disease. 
o Unlikely - occurred within a reasonable time frame after 
administration/discontinuation of the study medication, but there is a likely 
association of an intercurrent/underlying medical condition or other drugs. 
• Related. 
o Possible - occurred in a reasonable time after study-medication 
administration, but could be related to concurrent drugs or underlying disease. 
o Probable - occurred in a reasonable time after study-medication 
administration, is unlikely to be attributable to concurrent drugs or underlying 
disease, and there is a plausible mechanism to implicate the study medication. 
o Definite - occurred in a reasonable time after study-medication administration 
and cannot be explained by concurrent drugs or underlying disease. The AE 
should respond to dechallenge/rechallenge, however, this is not mandatory 
before assigning a definite causality. 
The Medical Monitor is the initial contact person for protocol-related questions or discussion of 
AEs. The contact information for the Medical Monitor as well as other emergency contact 
information can be found in Table 1 of this protocol. 
12.4. 
Immediately Reportable Events 
The following medical events must be immediately reported to the Sponsor: 
• SAE 
• Pregnancy 
Emergency contact information can be found in Table 1. 
12.4.1. 
Serious Adverse Event 
If the Investigator or study center staff becomes aware of a SAE that occurs in a study subject 
from the time that informed consent is signed through 30 days following the last dose of the 
study medication, this must be reported within 24 hours to PPD-PVG, the medical monitor, and 
Sunovion responsible physician whether considered related or unrelated to the study medication. 
SAEs occurring from the time of informed consent through 14 days following last dose of the 
study medication also must be recorded on the CRF and the data recorded should match that on 
the SAE form. 
Following the end of subject participation in the study, the Investigator or an authorized delegate 
should report SAEs “spontaneously” to PPD-PVG if considered at least possibly related to the 
study medication. 


Protocol Study No. SEP360-322, Version 4.00  
Dasotraline 
 
 
Confidential and Proprietary 
58 
13 Jun 2017 
 
Serious AEs will be followed until resolution, loss to follow-up, stabilization of condition, or the 
event is otherwise explained. 
In addition to the initial notification, an initial SAE form as applicable must be completed and 
signed and sent via fax or email (see Table 1) to PPD-PVG within 1 business day of the 
Investigator or study site staff becoming aware of the event. The SAE report form must be 
signed by the Investigator or appropriate designee. The Sponsor provides the SAE form used to 
report SAEs. 
The Sponsor or designee will promptly notify all study sites and Investigators of a SAE that is 
determined to be expedited to the Regulatory Authorities in accordance with applicable law(s) 
and regulation(s). These SAEs must be promptly reported to the Institutional Review Board 
(IRB) by the Investigator or the appropriate person at the site. 
12.4.2. 
Pregnancy 
Pregnancies that occur from the time that informed consent is signed through 30 days following 
the last dose of the study medication will be collected and reported on the Pregnancy Event Form. 
If a subject becomes pregnant during the course of the study, she will be instructed to 
immediately stop taking the study medication. Further, the subject will be instructed to return 
promptly/within 48 hours of the first notification of pregnancy to the research site and undergo a 
serum pregnancy test, as confirmation of pregnancy. If positive, the subject will no longer 
receive any additional study medication. All pregnancies, whether or not the subject received any 
additional study medication, will be followed until resolution (ie, termination [voluntary or 
spontaneous] or birth). 
If a pregnancy is reported for the study subject’s partner, the study subject must agree to 
complete abstinence for the duration of the study or until resolution of the pregnancy, whichever 
comes first, or discontinue study drug and withdraw from the study. If the subject chooses to 
withdraw from the study, continued abstinence is recommended for 30 days after the last dose of 
study medication. 
If a pregnancy is reported for the study subject’s partner, the Sponsor’s representative will 
provide instructions on how to collect pregnancy information in accordance with local 
requirements. Proper consent to collect the partner’s information will be obtained before the 
collection of any information. 
To report a pregnancy, the Pregnancy Event Form must be completed and sent via fax to 
PPD-PVG within 1 business day of the Investigator or study site staff becoming aware of the 
pregnancy. The Sponsor provides the Pregnancy Event Form. 
Pregnancy itself is not regarded as an AE unless there is a suspicion that the study medication 
may have interfered with the effectiveness of a contraceptive medication or other AEs were 
detected.

TERMINATION OF SUBJECT FROM 
STUDY/DISCONTINUATION OF STUDY DRUG 
13.1. 
Criteria for Study Drug Discontinuation 
Subjects may be discontinued from the study drug at any time during the treatment period. The 
possible reasons for discontinuation of study drug are as follows: 
• Adverse event 
• Lack of efficacy (specify) 
• Lost to follow-up (specify) 
• Non-compliance with study drug (specify) 
• Protocol violation (specify) 
• Pregnancy 
• Withdrawal by subject (specify) 
• Other (specify) 
If at any time during the course of the treatment period, in the opinion of the Investigator, the 
subject may no longer safely participate due to a change in medical status (eg, experiences an 
AE, becomes pregnant), the subject must be discontinued from the study drug. 
The reason and information for study drug discontinuation will be recorded on the appropriate 
CRF. In case of death, the date of death should be captured on the CRF. 
13.2. 
Clinical Assessments After Study Drug Discontinuation 
Subjects who discontinue study medication before completion will be asked to return to the site 
and complete the EOT visit assessments (Section 11.5.2.4), as soon as possible following 
discontinuation of study drug, and complete the study medication withdrawal assessments and 
visits (Section 11.5.3). 
13.3. 
Criteria for Subject Termination from the Withdrawal Period 
Subjects may terminate during the withdrawal period for any reason. The possible reasons for 
termination during the withdrawal period are as follows: 
• Adverse event. 
• Lost to follow-up (specify). 
• Protocol violation (specify). 
• Pregnancy. 
• Withdrawal by subject (specify). 
• Other (specify).

STUDY TERMINATION 
The Sponsor reserves the right to discontinue the study at this site or at multiple sites for safety 
or administrative reasons at any time while ensuring that early termination does not compromise 
subjects’ safety or well-being. In particular, a site that does not recruit at an acceptable rate may 
be closed. Should the study be terminated and/or the site closed for whatever reason, all 
documentation and study medications pertaining to the study must be returned to the Sponsor or 
its representative. 
If, in the opinion of the Investigator, clinical observations suggest it may be unsafe to continue, 
the Investigator may terminate part or the entire study after consultation with the Sponsor. 
In the event of study or site termination, subjects who discontinue study medication before 
completion will be asked to return to the site and complete the EOT visit assessments 
(Section 11.5.2.4) as soon as possible after discontinuation of study drug and complete the study 
medication withdrawal visits and calls (Section 11.5.3).

STATISTICS 
The Statistical Analysis Plan (SAP) will provide details on the statistical methods planned for 
this study and will be finalized before data base lock. 
15.1. 
Sample Size 
Subjects who complete the double-blind treatment period of the core study, sign the consent, and 
meet all entry criteria will be included in this study. The double-blind core study SEP360-221 
plans to randomize approximately 300 subjects and the double-blind core study SEP360-321 
plans to randomize approximately 480 subjects. It is estimated that approximately 500 subjects 
will be eligible for enrollment in this study based on the number of subjects expected to complete 
treatment in the core study. 
15.2. 
Analysis Populations 
Safety Population: The safety population will include all subjects who receive at least one dose 
of study medication. The safety population mainly is used for the data analyses of the safety data 
collected through Week 52 or during the open-label treatment period. 
Withdrawal Population: The withdrawal population includes all subjects who receive at least one 
dose of study medication, and either early terminate from the study drug during the OL treatment 
period or complete the 52-week OL treatment period, and have at least 1 assessment after the last 
study drug administration for any evaluation. The withdrawal population is used to summarize 
the safety and effectiveness assessments collected in the withdrawal period. 
All effectiveness and safety evaluations will be summarized by analysis group based on the 
safety population and withdrawal population separately, when applicable. 
15.3. 
Data Analysis 
Unless otherwise specified, safety data will be presented separately by analysis group for the 
open-label treatment period (for data collected up to the end of open-label treatment period) and 
withdrawal period (for data collected during the withdrawal period), as appropriate. Since this is 
an uncontrolled open-label extension, no statistical comparisons will be conducted and no 
inferential statistics on effectiveness and safety will be presented. 
15.3.1. 
Analysis Group 
A total of 2 analysis groups will be formed based on a subject’s previous participation in the core 
studies (ie, subjects previously randomized to dasotraline and subjects previously randomized to 
placebo). Group “All-Das” that combines these 2 analysis groups will be also presented. 
Summary tables, wherever applicable, will be presented by above analysis group, respectively. 
 Pbo-Das: Subjects previously randomized to placebo in studies SEP360-221 or 
SEP360-321 
 Das-Das: Subjects previously randomized to dasotraline group in studies SEP360-221 or

applicable. 
15.3.2. 
Definitions of Assessments 
The following definitions will be used for assessments: 
• Double-blind (DB) Baseline (ie, Baseline assessment of the double-blind study [core 
study]): the last assessment made on or before double-blind randomization as 
described in the core protocols; 
• OL Baseline (ie, Endpoint assessment of the double-blind treatment period of core 
study) or Baseline assessment of the open-label study (SEP360-322): the last 
assessment made during the double-blind treatment period, as described in the core 
protocols; 
• Week 52 Endpoint/Withdrawal Baseline: the last post-OL Baseline assessment made 
prior to or at Week 52 visit. 
• Withdrawal Endpoint: the last post-Withdrawal Baseline assessment made prior to or 
at Week 55 visit. 
Continuous variables will be summarized using descriptive statistics (N, mean, standard 
deviation [SD], median, range, 95% confidence interval [CI] as needed). Where changes are 
reported, the reference will be to “DB Baseline”. Where relevant, changes from “OL Baseline” 
will also be reported.

15.3.3. 
Safety Analysis 
The CSSA and DESS, which are used to assess physical dependence and withdrawal symptoms, 
are collected only at the Week 52 endpoint and in the withdrawal period; all other safety data are 
to be collected in both treatment period and withdrawal period and will be presented by analysis 
group for the open-label treatment period and withdrawal period, separately, as appropriate. 
15.3.3.1. Adverse Events 
All AEs will be coded using Medical Dictionary for Regulatory Activities (MedDRA) version 
18.0 or higher. 
Treatment-emergent adverse events (TEAEs) are those reported adverse events with onset data 
on or after the first day of the open-label treatment period through 7 days after study drug 
discontinuation (14 days for serious adverse events and deaths). The start of the open-label 
treatment period is defined as Day 1 for subjects previously randomized to placebo group and the 
OL Baseline visit date for subjects previously randomized to dasotraline groups. 
A discontinuation-emergent adverse event (DEAE) is defined as an AE which has an onset after 
the last dose date of study drug through the Week 55 visit (ie, the last study visit in the 
withdrawal period). 
Table summaries of AEs will be limited to TEAEs and DEAEs. All AE data will be displayed in 
data listings. For the sake of simplicity, hereafter TEAE is referred to as AE in this section. 
The overall incidence (ie, number and percent of subjects with one or more AE in each category) 
of AEs, serious AEs, deaths, AEs leading to discontinuation, study drug-related AEs, study 
drug-related AEs leading to discontinuation, serious AEs leading to discontinuation, and serious 
study drug-related AEs, and serious study drug-related AEs leading to discontinuation will be 
summarized by analysis group. 
The AEs also will be summarized by system organ class (SOC) and preferred term (PT) by 
presenting the number and percentage of subjects with each AE category. The incidence of AEs 
(by preferred term, grouped by SOC, and presented by analysis group) also will be summarized 
by severity, by the relationship to study medication, by the action taken regarding the study 
medication, as well as by the outcome. 
The incidence of AEs of special interest, including but not limited to neuropsychiatric-related 
and cardiovascular-related AEs, will be summarized by analysis group. For time to the earliest 
onset of insomnia, Kaplan-Meier curves will be plotted by analysis group. 
The overall incidence of DEAEs and serious DEAEs will be summarized by analysis group. The 
DEAEs also will be summarized by SOC and PT by presenting the number and percentage of 
subjects with each AE category. 
15.3.3.2. Columbia Suicide Severity Rating Scale (C-SSRS) 
The number and percentage of subjects with suicidal ideation and/or suicidal behavior, 
emergence or worsening of suicidal ideation or suicidal behavior will be summarized by analysis 
group for the open-label treatment period and the withdrawal period, separately.

15.3.3.3. Other Safety Assessments 
Other safety assessments, including but not limited to laboratory values, ECG, vital signs, 
weight, BMI, and neurological exam, will be summarized as below. BMI at a study visit will be 
derived per weight assessed at each open-label study visit and the height collected at Screening 
in the core studies. 
Treatment Period 
Descriptive statistics will be provided for observed values and changes from DB baseline and OL 
baseline by study visit and analysis group for continuous variables; for categorical variables. 
Frequencies and percentages by study visit and analysis group will be reported. In addition, for 
selected parameters of laboratory values, ECG, vital signs, and weight, the number and 
percentage of subjects with markedly abnormal values will be presented. 
Withdrawal Period 
Descriptive statistics of continuous variables will be provided for observed values and changes 
from Week 52 Endpoint by study visit and analysis group; for categorical variables, frequencies 
and percentage by study visit and analysis group will be reported. 
15.3.3.4. Physical Dependence and Withdrawal Symptoms 
For continuous data used to assess physical dependence and withdrawal symptoms (ie, CSSA 
total score, DESS total score, MADRS total score, and HAM-A total score), descriptive statistics 
of the observed values and changes from Week 52 Endpoint will be summarized by analysis 
group and visit for the withdrawal period. 
15.3.3.5. Concomitant Medications 
The number and percentage of subjects taking concomitant medication will be summarized by 
anatomical therapeutic chemical (ATC) classification and preferred name by analysis group. 
15.3.4. 
Analyses for Effectiveness and Subject-Reported Health Status 
For BE-CGI-S score, EDE-Q modified global score and subscales scores (restraint, shape concern, 
weight concern), EDE-Q modified items 4-6 scores, SDS total score and subscale scores, and 
SF-12 (subjects from Study SEP360-221 only) physical component and mental health 
component scores, descriptive statistics (N, mean, SD, median, range) of observed values will be 
summarized by analysis group at DB baseline, OL baseline (when applicable), each scheduled 
assessment in the treatment period, and Week 52 Endpoint. In addition, similar summary 
statistics as described above and 95% CI of changes from DB baseline and OL baseline will be 
presented. Confidence intervals will be based on means and standard deviations estimated 
without adjustment for any center or baseline effects. 
For time to early discontinuation, Kaplan-Meier curves will be plotted by analysis group. 
15.3.5. 
Interim Analysis 
No interim analysis is planned.

ASSURANCE 
16.1. 
Data Collection/Electronic Data Capture (EDC) 
The results from data collected during the study (except clinical laboratory test results, 
electrocardiogram results, and IXRS data) will be recorded in the subject’s electronic CRF. The 
study sites will use an electronic data capture (EDC) system that is compliant with relevant FDA 
regulatory requirements per 21 CFR Part 11, Medidata Rave®. The SDS, C-SSRS, EDE-Q 
modified, MADRS, BE-CGI-S, HAM-A, CSSA, DESS, and SF-12 will be completed on paper 
forms and then entered into the EDC system. Password protected access to the EDC system will 
be via a secure website. Data queries and data corrections will be handled through the same 
system. All transactions within the EDC system are fully documented within an electronic audit 
trail. Each set of completed CRFs must be reviewed and electronically signed and dated by the 
Investigator.

intervals not to exceed one year or as otherwise specified by the IRB. The Sponsor must be 
supplied with written documentation of continued review of the clinical research. 
The Investigator must promptly inform their IRB of all SAEs reported by subjects enrolled in the 
study or other safety information reported from Sponsor/CRO in accordance with applicable 
law(s) and regulation(s). 
17.3. 
Informed Consent 
The informed consent form will be approved by the Sponsor/CRO before submission to the IRB. 
The Sponsor/CRO may provide a template informed consent form to be qualified by each 
research facility to conform to local requirements. All informed consent forms must contain the 
minimum elements as mandated by ICH GCP, applicable local law(s) and regulations and will be 
subject to Sponsor/CRO approval as well as IRB approval. The Sponsor/CRO may submit 
informed consent forms to a central IRB for review and approval or favorable opinion contingent 
upon prior the Investigator permission and review. 
Before recruitment and enrollment, each prospective subject will be given a full explanation of 
the study, allowed to read the approved informed consent form and be provided ample time and 
the opportunity to ask any questions that may arise. Once all questions have been answered and 
the Investigator is assured that the prospective subject understands the implications of 
participating in the study, the prospective subject will be asked to give consent to participate in 
the study by signing the informed consent form. As part of the consent process, each prospective 
subject must consent to direct access to his/her medical records for study-related monitoring, 
auditing, IRB review, and regulatory inspection. It should be clearly explained to each 
prospective subject that participation in each and every clinical visit and assessment is expected. 
The subject may be discontinued from study medication, but that does not necessarily negate the 
expectation that the subject will continue to participate in the study through the final 
visit/assessment. The Investigator will provide a copy of the signed informed consent form to 
each subject, and will record the date of the informed consent on the CRF. 
If an amendment to the protocol changes the subject participation schedule in scope or activity, 
or if important new information becomes available that may be relevant to the subject’s consent, 
the informed consent form must be revised, submitted to the IRB for review and approval or 
favorable opinion. The revised informed consent form must be used to obtain consent from a 
subject currently enrolled in the study if he or she is affected by the amendment. The revised 
informed consent form must be used to obtain consent from any new subjects who are enrolled 
into the study after the date of the approval or favorable opinion of the protocol amendment. 
17.4. 
Subject Privacy 
The Sponsor (or Sponsor representative) or any designees affirm uphold the subjects 
confidentiality. The subject will be identified by unique code and initials only; full names will be 
masked prior to transmission to the Sponsor. The confidentiality of the subject’s personal data 
shall be protected in accordance with appropriate laws and regulations.

All revisions and/or amendments to this protocol must be approved in writing by the Sponsor 
and the appropriate IRB. The Investigator will not make any changes to the conduct of the study 
or the protocol without first obtaining written approval from the Sponsor and the IRB, except 
where necessary to eliminate an apparent immediate hazard to a study subject. 
Emergency deviations or modifications may be initiated without Sponsor or IRB approval or 
favorable opinion, only in cases where the deviation or modification is necessary to eliminate or 
avoid an immediate apparent hazard to subjects. Emergency deviations or modifications must be 
reported to the Sponsor/CRO and the IRB immediately/within five business days of the 
occurrence, or in accordance with applicable regulatory requirements. 
17.6. 
Records Retention 
The Investigator/the site must arrange for retention of study records at the site for at least 
15 years from time of participation in the study or longer in accordance with applicable 
regulations and Sponsor standard operating procedures (SOPs). The Investigator/site should take 
measures to prevent accidental or premature destruction of these documents. Documents cannot 
be destroyed without written Sponsor authorization. The Sponsor will inform the Investigator/the 
site when the destruction of documents is permitted. 
17.7. 
Inspection of Records 
In the event of an inspection, the Investigator agrees to allow representatives of the Sponsor and 
its representative, the regulatory authorities’ access to all study records. The Investigator will 
promptly notify the Sponsor/CRO of all requests to inspect a Sunovion-sponsored study by

APPENDIX V. ABUSE POTENTIAL MONITORING PLAN 
Overview of Abuse Potential Monitoring Plan 
Dasotraline is a new chemical entity being investigated for the treatment of Binge Eating 
Disorder (BED). Dasotraline is a diastereomer of the major metabolite of sertraline but is not a 
metabolite of sertraline, nor is it converted to the demethylated metabolite of sertraline in vivo. 
Dasotraline is a potent inhibitor of the reuptake of serotonin (5-HT), norepinephrine (NE), and 
dopamine (DA) via the respective transporters SERT, NET, and DAT, with preferential 
inhibition of the dopamine transporter (DAT) and norepinephrine transporter (NET) relative to 
the serotonin transporter (SERT) without significant off-target activities. Clinical studies 
demonstrated central SERT occupancies in healthy subjects well below those attained at DAT, in 
addition decreases in 3,4-dihydroxyphenylglycol (DHPG) were observed, indicating central NET 
inhibition. This pharmacological profile warrants the implementation of an Abuse Potential 
Monitoring Plan, which surpasses the clinical monitoring, and adverse event (AE) reporting 
historically implemented in development programs for SSRIs. 
The Abuse Potential Monitoring Plan (APMP) for dasotraline has been designed to detect 
potential abuse of the compound and to more closely monitor AEs consistent with the 
pharmacology. The plan will detect irregularities in the handling of dasotraline in clinical trials 
and identify the misuse of dasotraline or other psychoactive substances. Moreover, the APMP 
provides a process by which events subject to additional monitoring are identified, processed, 
and reviewed. Events subject to additional monitoring were identified based on the 
pharmacology of dasotraline, as well as adverse event profiles of compounds with similar 
mechanisms of action. 
Procedure for Managing Medication Irregularities 
Defining Threshold Criteria 
The purpose of this procedure is to capture information about all medication-handling 
irregularities that meet the predefined threshold criteria. All instances meeting the medication 
irregularity threshold criteria will require a clinical risk assessment by the investigator with 
classification of the nature of the irregularity. The investigator will be required to complete 
Attachment A, the Medication Handling Irregularity (MHI) form in these situations. 
For clinical trials utilizing dasotraline, we define the threshold criteria for medication 
irregularities as any one of the following: 
• 10% or more of dispensed drug is either used in excess of prescribed dose or is 
unaccounted for; and/or 
• Suspected abuse or diversion of dasotraline; and/or 
• Suspected abuse of any other substance including alcohol, illicit substances, and 
over-the-counter (OTC) medications or prescription drugs.

Instances of Medication Irregularity 
For all instances where the predefined threshold criteria are met covering medication 
irregularities, the investigator must complete the Medication Handling Irregularity (MHI) form 
(Attachment A) and fax to the contact provided within 3 business days of its occurrence or 
discovery every time a threshold medication handling irregularity occurs. The contact will fax 
the completed MHI form to Sunovion within 1 business day of receipt and determine whether 
further action is warranted (ie, discontinuation of subject due to noncompliance with study 
protocol, education of the subject, etc). Attachment B displays the process flow for handling 
medication irregularities. Any instance of medication irregularity may further be classified as an 
event subject to additional monitoring (ESAM). 
The management of documented medication handling irregularities will be driven by the 
particular classification of the irregularity. As shown on Attachment A, items coded #1-3 
describe situations of accounting errors and/or noncompliance with study procedures without 
evidence of study medication misuse or abuse of other substances. In these instances (code #1-3 
on the MHI form), the investigator will complete Attachment A and fax to the contact provided 
within 3 business days of knowledge of the irregularity. 
 
Suspected or Known Abuse or Diversion of Study Medication 
All cases of suspected or known abuse or diversion of study medication should be documented 
on the MHI form and coded #4. The investigator will complete Attachment A and fax to the 
contact provided within 3 business days of knowledge of the irregularity. For all cases of 
medication irregularities coded as #4, the investigator will attempt to obtain a urine drug screen 
from the subject, perform early termination procedures and discontinue the subject from the 
study. 
 
Suspected or Known Abuse of Alcohol or Other Substances 
The abuse of alcohol, illicit substances, OTC medication or prescription drugs while a subject is 
participating in a dasotraline clinical trial should be documented on the MHI form and coded #5. 
The investigator will complete Attachment A and fax to the contact provided within 3 business 
days of knowledge of the irregularity. For all cases of medication irregularities coded as #5, the 
investigator will attempt to obtain a urine drug screen from the subject, perform early 
termination procedures and discontinue the subject from the study. 
 
Event Subject to Additional Monitoring (ESAM) 
A key objective of the Abuse Potential Monitoring Plan is to monitor for instances of abuse or 
diversion of the study medication and other psychoactive substances. In addition to monitoring 
for irregularities in medication handling, AEs that may be suggestive of a developing abuse 
issue, will also receive special attention. The following adverse experiences or related signs and 
symptoms will require additional monitoring. This list is a guide as to the types of events that 
require additional medical surveillance; it is not comprehensive and other events may be

identified that require similar medical surveillance. Subjects experiencing an event subject to 
additional monitoring may need to be discontinued from the study.

To ensure clarity and completeness of information, all Events Subject to Additional Monitoring 
will require the preparation of a narrative by the investigator. This narrative will be reviewed by 
the sponsor/investigator to determine if the subject should be discontinued from the study. A 
narrative summary template will be provided to the investigators (Attachment C). 
Handling of the Event Subject to Additional Monitoring (ESAM) 
• Investigators will report all Events Subject to Additional Monitoring with narratives 
to the Medical Monitor within 24 hours (Attachment C) 
• The medical monitor will review all ESAM in real time and forward a copy of the 
report to the sponsors’ Medical Director within one 1 business day 
 
Urine Drug Screens 
The protocol incorporates exclusion criteria targeting individuals with a history of substance use 
disorders (eg, alcohol abuse or dependence and illicit drug abuse or dependence). The protocol 
includes urine drug screens at baseline and at various post-baseline visits as well as providing the 
investigator with the discretion to obtain random urine drug screens. Investigators will be 
directed to obtain urine drug screens in instances where there is known or suspected abuse of 
study medication and/or other substances.

Introduction 
This statistical analysis plan (SAP) contains the definitions of analysis populations, derived 
variables, and statistical methods for the analyses of efficacy and safety data from study 
Dasotraline SEP360-322 for subjects continued from core studies SEP360-221 or SEP360-321.  
Study completion status of the two core studies is given below: both studies were completed. 
Study SEP360-221 clinical database was locked on Nov 15, 2016 and study SEP360-321 clinical 
database was locked on June 25, 2018.   
One full interim analysis was planned to support regulatory filing of New Drug Application 
(NDA) submission for binge eating disorder (BED). The interim analysis was conducted per data 
snapshot with data cut date of Aug 31, 2018. In total there are two separate and independent data 
analyses for study SEP 360-322, one for the interim analysis and the other for final analysis. The 
final database lock will occur when the study is completed and a subsequent final analysis of 
study SEP 360-322 will be performed. 
This SAP is developed based on the version of the study protocol with Amendment 3.0 dated 
June 13, 2017. It outlines analyses to be conducted for the final database lock for data collected 
through the withdrawal period. A separate SAP for the interim analysis was prepared and 
finalized prior to data snapshot for the interim data cut.   
If additional analyses are required to supplement the planned analyses described in this SAP after 
the final database lock, they may be performed and will be identified and documented in Clinical 
Study Report (CSR).

Study Objectives 
2.1. 
Primary Objective 
The primary objective of the study is to evaluate the long-term safety and tolerability of flexibly-
dosed dasotraline (4, 6, or 8 mg/day) in adults with BED who have completed a prior dasotraline 
study in BED by: 
 The incidence of AEs, discontinuations due to AEs, and serious AEs (SAEs)  
 The frequency and severity of suicidal ideation and suicidal behavior using the Columbia 
– Suicide Severity Rating Scale (C-SSRS)  
 Changes in 12-lead electrocardiograms (ECGs), vital signs, body weight, body mass 
index (BMI), and clinical laboratory results 
2.2. 
Secondary Objective 
The secondary objects are:  
 To assess potential withdrawal effects of dasotraline using the following assessments 
(administered during the withdrawal period):  
 Cocaine Selective Severity Assessment (CSSA)  
 Discontinuation-Emergent Signs and Symptoms (DESS) Scale  
 Symptoms of anxiety utilizing the Hamilton Anxiety Rating Scale (HAM-A)  
 Symptoms of depression utilizing the Montgomery-Asberg Depression Rating 
Scale (MADRS)  
 To assess the abuse potential of dasotraline utilizing a comprehensive abuse potential 
monitoring plan (APMP)  
 To evaluate the long-term effectiveness of flexibly-dosed dasotraline in the treatment of 
adults with BED as measured by the following:  
 Eating Disorder Examination Questionnaire (EDE-Q) modified  
 Binge-eating Clinical Global Impressions - Severity (BE-CGI-S)  
 Sheehan Disability Scale (SDS)  
 To assess subject-reported health status using the Medical Outcomes Study 12-Item Short 
Form Survey Instrument (SF-12) (SF-12 collected only for subjects enrolling in this study 
after completing core study SEP360-221).

3. 
Study Design 
This is a Phase 3, 12-month, multicenter, open-label, flexibly-dosed, safety study in adults with 
BED. This study is projected to enroll approximately 500 subjects based on the number of 
subjects expected to complete treatment in the core studies (ie, SEP 360-221 or SEP360-321). 
Informed consent is obtained from all subjects after all procedures from the core study have been 
completed and before any study procedures unique to this study are performed. Safety and 
tolerability is monitored throughout the study by AE reports, physical and neurological 
examinations, 12-lead ECG, vital signs, body weight, BMI, clinical laboratories (hematology, 
chemistry, urinalysis, hemoglobin A1c, and lipid panel), and C-SSRS. Effectiveness will be 
evaluated using the BE-CGI-S, EDE-Q modified, and SDS. Subject-reported health status will be 
assessed using the SF-12 (subjects from Study SEP360-221 only). Assessment of potential 
withdrawal effects of dasotraline will be conducted via administration of the CSSA, DESS, 
HAM-A, and MADRS at the end of treatment and during the 3-week study medication 
withdrawal period.  
A comprehensive Abuse Potential Monitoring Plan (APMP, see Protocol Section 24) for 
dasotraline designed to detect potential abuse of the compound and to more closely monitor AEs 
consistent with the known pharmacology for dasotraline will be implemented.  
An independent Data and Safety Monitoring Board (DSMB) reviews safety data including data 
on adverse events (AEs) and serious adverse events (SAEs) at regular intervals. 
Subjects self-administers study drug on an outpatient basis for 12 months, once a day at 
approximately the same time each morning with or without food, including on the days when 
clinic visits occur. Subjects meeting all inclusion and no exclusion criteria start taking open-label 
study drug on Day 1, the morning following the open-label (OL) Baseline visit (ie, Week 12 visit 
in the core study). 
The total daily dose remains between 4 mg/day and 8 mg/day for the 12-month treatment period. 
Dasotraline is dosed at 4 mg/day for the first 2 weeks of the study. At the Week 2 visit, the dose 
may be increased to 6 mg/day. Thereafter the dose may be increased or decreased by 2 mg/day, 
as necessary for effectiveness or tolerability reasons at the discretion of the investigator. A 
minimum of 8 days is required between dose increases. Dose decreases may be made at less than 
8 day intervals, at the investigator’s discretion, for reasons of safety or tolerability. If, in the 
judgment of the investigator, the subject does not tolerate the minimum required dose (4 mg/day), 
he or she is discontinued from the study. All changes in study drug dose begins the morning after 
the visit at which the dose change decision is made and using the new package of study drug. 
The study consists of a baseline visit, 12-month open-label treatment period, and 3-week study 
drug withdrawal period as shown in the Study Schematic (protocol section 7.1 Figure 1). During 
the treatment period, subjects will return to the clinic at the end of 2 and 4 weeks for clinical 
evaluation and thereafter will return to the clinic once every 4 weeks during the treatment period

for scheduled visits. At the approximate midpoint between the scheduled monthly visits (ie, 14 ± 
2 days after a visit), the site staff will contact the subject via telephone, text, or email in order to 
monitor for SAEs, AEs, and concomitant medications, as well as to remind subjects about 
adherence to study drug administration, and upcoming visits. If necessary, an unscheduled visit 
can be arranged. 
Subjects attend weekly visits during the 3-week study drug withdrawal period. Assessment of 
potential withdrawal effects of dasotraline will be conducted via administration of the CSSA, 
DESS, HAM-A, and MADRS at the end of treatment. Subjects will undergo assessments every 
other day and weekly as follows: The CSSA and DESS will be completed every other day during 
the 3-week study medication withdrawal period. Clinical site staff will call the subject every 
other day, beginning the second day after the last dose of study drug, unless a clinic visit is 
scheduled for that day. Phone contacts may be made up to 3 times per day if the clinical site staff 
are unable to contact the subject on the first 2 attempts. If the subject cannot be contacted on a 
given day, during the next contact the study site staff will retrospectively collect the missed 
CSSA and DESS, in addition to the current day’s CSSA and DESS, as necessary. Clinical site 
staff will record the responses in the subject’s source information and in the case report form 
(CRF) with the contact date and time. The CSSA, DESS, HAM-A, and MADRS also will be 
administered at each weekly visit during the withdrawal period. 
A window of ± 1 day is allowed for each weekly clinic visit and telephone call during the study 
medication withdrawal period.  
After the last withdrawal period visit, all subjects will be referred for follow-up care as 
determined by the investigator. 
The schedule of assessments for this study is in Attachment 9.1; also see protocol Section 11.5 
for study visits and assessments detail. 
3.1. 
Determination of Sample Size 
Subjects who complete the double-blind treatment period of the core study, sign the consent, and 
meet all entry criteria are included in this study. The double-blind core study SEP360-221 
planned to randomize approximately 300 subjects and the double-blind core study SEP360-321 
planned to randomize approximately 480 subjects. It is estimated that approximately 500 
subjects are eligible for enrollment in this study based on the number of subjects expected to 
complete treatment in the core studies. 
3.2. 
Randomization, Stratification and Blinding 
This is an open-label extension study, therefore randomization and blinding is not employed.

Effectiveness and Safety Variables  
5.1. 
Effectiveness Variables 
5.1.1. Binge-eating Clinical Global Impression-Severity (BE-CGI-S) 
The BE-CGI-S is a single value, clinician-rated assessment of illness severity, and 7-point scale 
with range from 1 = normal, not at all ill; 2 = borderline mentally ill; 3 = mildly ill; 4 = 
moderately ill; 5 = markedly ill; 6 = severely ill; 7 = among the most extremely ill subjects. A 
higher score is associated with greater illness severity.  
BE-CGI-S score is collected at Weeks 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52/EOT in the 
open-label treatment period, and at Weeks 53, 54 and 55/EOS for subjects who enter the 
withdrawal period. 
5.1.2. Eating Disorder Examination Questionnaire (EDE-Q) modified and 
Comparison with EDE-Q and EDE-Q Brief Version (EDE-Q7)  
The Eating Disorder Examination Questionnaire (EDE-Q) is a self-report version of the eating 
disorder examination (EDE) (Fairburn-1994). Like the EDE, the EDE-Q measures eating-
disorder psychopathology in the past 28 days and over longer intervals for diagnostic items. 
EDE-Q generates two types of data. First, it provides frequency data (ie, numerical data) on key 
behavioral features of eating disorders in term of number of episodes of the behavior and in some 
instance number of days which behavior has occurred; Second, they provide ratings (ie, 
categorical data), 4 subscale scores, and an EDE-Q global score reflecting the severity of aspects 
of the psychopathology of eating disorders. The 4 subscale scores are Restraint, Eating Concern, 
Shape Concern, and Weight Concern.  Severity rating ranges 0- 6, where 0 represents absence of 
the feature and 6 represents an extreme degree. Frequency ratings range from 0 to 6 where 
0=’No days’ or absence of the feature, 6=’every day’. 
Both the Eating Disorder Examination Questionnaire Brief Version (EDE-Q7) and EDE-Q 
modified  are shorter versions of the EDE-Q.  
EDE-Q7 comprises 7 items to generate a global score and 3 subscale scores (Restraint, Shape 
Concern, and Weight Concern). The EDE-Q7 along with 3 items (see below) to assess binge 
eating, including the number of binge eating days, is referred to as the EDE-Q modified and is 
used in this study. 
 Item 4: Over the past 28 days, how many times have you eaten what other people would 
regard as an unusually large amount of food (given the circumstances)? 
 Item 5: On how many of these times did you have a sense of having lost control over 
your eating (at the time that you were eating)? 
 Item 6: Over the past 28 days, on how many DAYS have such episodes of overeating 
occurred (i.e., you have eaten an unusually large amount of food and have had a sense of 
loss of control at the time)?

For EDE-Q, EDE-Q Modified, and EDE-Q7, the subscale scores are calculated as average of the 
corresponding individual scores. If any individual score  of the subscale is missing, the 
corresponding subscale score will be set as missing and no imputation will be done. An EDE-Q 
global score is calculated as average of 4 EDE-Q subscale scores, an EDE-Q7 global score is 
calculated as average of 3 EDE-Q7 subscale scores, and an EDE-Q Modified global score is 
calculated as average of 3 EDE-Q Modified subscale scores. The EDE-Q global score, EDE-Q 
modified global score, and EDE-Q7 global score will be missing if any of corresponding 
subscale scores is missing. For EDE-Q, EDE-Q modified, and EDE-Q7, higher scores on the 
global score and subscale scores indicate greater levels of symptomatology; the global scores and 
subscale scores of EDE-Q Modified and EDE-Q7 are equivalent.  
EDE-Q, EDE-Q7, and EDE-Q modified are all designed to collect the data in the past 28 days.  
For subjects continued from study SEP360-221, EDE-Q modified is collected at open label 
baseline visit; for subjects continued from study SEP360-321, EDE-Q modified is carried over 
from W12/EOT visit in study SEP360-321. In addition, EDE-Q modified is collected at Weeks 4, 
8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52/EOT in the open-label treatment period. 
5.1.3. Sheehan Disability Scale (SDS) 
The Sheehan Disability Scale (SDS) is to assess functional impairment in 3 domains: (1) 
work/school; (2) social life; and (3) home life. The subject rates the extent to which work/school, 
social life and home life have been impaired by his/her symptoms on a 10-point anchored visual 
analog scale (VAS). The subject’s responses for each domain are rated on the following scale: 0 
= not at all; 1-3 = mildly; 4-6 = moderately; 7-9 =markedly; 10 = extremely. The 3 items can be 
combined into a single global measure of impairment (SDS total score) that ranges from 0 
(unimpaired) to 30 (highly impaired). If any of the 3 SDS subscale scores is missing at a visit, 
the SDS total score for that visit is also missing. A higher subscale score and total score are 
associated with greater illness severity. 
SDS is collected at Weeks 12, 24, 36, 52/EOT in treatment period, and at Week 55/EOS for 
subjects who enter the withdrawal period.

Patient-Reported Outcome (PRO)  
5.2.1. 12-Item Short Form Health Survey (SF-12) 
The SF-12 is a 12-item self-report questionnaire. The survey captures physical and mental 
health. There are 8 subscales including: Physical functioning, Role-physical, Bodily pain, 
General health, Vitality, Social Functioning, Role-emotional, Mental health. The responses are 
reported on a 3 or 5 point Likert scale, depending on the question. The SF-12 uses two items 
each to estimate scores for four of the eight health concepts (physical functioning, role-physical, 
role-emotional, and mental health). Scores for the remaining four health concepts (bodily pain, 
general health, vitality, and social functioning) are estimated using one item each. Physical 
Component Summary (PCS) and Mental Component Summary (MCS) are computed using the 
scores of twelve questions and range from 0 to 100, where a zero score indicates the lowest level 
of health measured by the scales and 100 indicates the highest level of health. 
SF-12 data will be provided by Optum. For details of data derivation, see Attachment 9.2.  
For subjects who continued from study SEP360-221 only, the SF-12 is collected at Weeks 12, 
24, 36 and 52/EOT and at Week 55/EOS for subjects who enter  the withdrawal period. SF-12 is 
not collected for subjects who continue from study SEP360-321.

Safety Assessment 
The safety assessments/endpoints are 
 adverse event (AE) reports,  including the incidence of overall AEs, serious AEs (SAEs), 
and AEs (or SAEs) leading to discontinuations 
 Clinical laboratory evaluations (serum chemistry, hematology, and urinalysis) 
 Clinical evaluations (vital signs including orthostatic effects, and 12-lead ECGs)  
 body weight and body mass index (BMI) 
 concomitant medication reports 
 physical examinations 
 Columbia – Suicide Severity Rating Scale (C-SSRS) 
 
The following safety measurements will also be collected to assess the occurrence of symptoms 
of withdrawal from dasotraline:  
 Cocaine Selective Severity Assessment (CSSA) 
 Discontinuation-Emergent Signs and Symptoms (DESS) Scale 
 Symptoms of anxiety utilizing the HAM-A

 Symptoms of depression utilizing the MADRS 
5.3.1. Columbia – Suicide Severity Rating Scale (C-SSRS) 
The C-SSRS is an instrument designed to systematically assess and track suicidal behavior and 
suicidal ideation throughout the trial. The strength of this suicide classification system is in its 
ability to comprehensively identify suicidal events while limiting the over-identification of 
suicidal behavior. The C-SSRS includes the following four sections: Suicidal Ideation, Ideation 
Intensity, Suicidal Behavior and Actual Suicide Attempts. The C-SSRS is administered by a 
trained rater at the site. 
Severity of suicidal ideation is rated on a 6-point scale from 0=’No ideation present’ to 
5=’Active ideation with plan and intent’. A score of 4 or 5 on this scale indicates serious suicidal 
ideation.  Subjects with Type 4 (active suicidal ideation with some intent to act, without specific 
plan) or Type 5 (active suicidal ideation with specific plan and intent) suicidal ideation during 
the study will be discontinued from the study and referred to a mental health professional. 
Suicidal ideation score is defined as the most severe suicidal ideation score (1-5 on the CSSRS) 
present at the assessment; assign a score of 0 if no ideation is present. The ideation intensity total 
score is calculated as summation of the five items from the Ideation Intensity scale: frequency, 
duration, controllability, deterrents, and reasons for ideation. If one or more of these 5 items are 
missing at a visit, no imputation will be made and the corresponding ideation intensity total score 
will be set as missing. Items corresponding to frequency and duration are each rated on a scale 
from 1 to 5 and items corresponding to controllability, deterrents, and reasons for ideation are 
each rated on a scale from 0 to 5. If the patient did not endorse any suicidal ideation, set the 
intensity rating to 0. Thus, the possible range for the intensity total score is 0 to 25.  
Suicidal behavior is collected as presence/absence of actual attempts, non-suicidal self-injurious 
behavior, interrupted attempts, aborted attempts, preparatory acts or behavior, and any suicidal 
behavior. In addition, the number of actual attempts, interrupted attempts, and aborted attempts 
is captured. Any attempt will be defined as suicidal behavior.  
The lethality associated with actual attempts is rated on a 6-point scale from 0=’No physical 
damage or very minor physical damage’ to 5=’Death’. Potential lethality of attempts is rated on a 
3-point scale from 0=’Behavior not likely to result in injury’ to 2=’Behavior likely to result in 
death despite available medical care’. 
For all study visits, the “Since Last Visit” version of the C-SSRS is administered. 
C-SSRS is collected at Weeks 2, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52/EOT in the open-
label treatment period, and at Weeks 53, 54 and 55/EOS for subjects who enter the withdrawal 
period.

5.3.2. Withdrawal Assessment for Physical Dependence and Withdrawal 
Symptoms 
Subjects who either are early terminated in the open-label treatment period or complete the 52-
week open-label treatment period need to complete the study medication withdrawal period 
assessments and visits.  
Assessment of potential withdrawal effects will be conducted via administration of the CSSA, 
DESS, HAM-A and MADRS at Week 52/EOT, then at Weeks 53, 54, and 55/EOS during the 3-
week study medication withdrawal period. The CSSA and DESS will also be completed during 
the 3-week study medication withdrawal period on non-clinic visit days. Clinical site staff will 
call the subject every other day during the study medication withdrawal period, beginning the 
second day after the last dose of study drug, unless a clinic visit is scheduled for that day. 
Clinical site staff will record the responses in the subject’s source information and in the CRF 
with the contact date and time. A window of ± 1 day is allowed for each weekly clinic visit and 
telephone call. If the subject cannot be contacted on a given day, during the next contact the 
study site staff will retrospectively collect the missed CSSA and DESS, in addition to the current 
day’s CSSA and DESS. 
5.3.2.1. 
Cocaine Selective Severity Assessment (CSSA) 
The CSSA is a clinician-administered scale designed to evaluate withdrawal signs and symptoms 
related to stimulants over the past 24 hours. Included in the CSSA are those symptoms most 
often associated with early cocaine abstinence, including change in appetite, depression, fatigue, 
anhedonia, anxiety, irritability, sleep disturbance, and inability to concentrate, paranoia, 
carbohydrate craving, bradycardia, and suicidality. The CSSA scale contains 18 items. All items 
except item 14, are scored 0 to 7 according to instructions generally with 0 = no symptoms and 7 
= maximum score on any individual item. Item 14 is scored 0 to 8 with 0 = no symptoms and 8 = 
maximum score. The score for each question will be summed to compute a total score ranging 
from 0 to 127 with higher score indicates severe withdrawal signs and symptoms. If the response 
to any question is missing, the total score will be missing. 
The CSSA is collected at Week 52/EOT, and Weeks 53, 54 and 55/EOS for subjects who enter 
the withdrawal period. 
5.3.2.2. 
Discontinuation-Emergent Signs and Symptoms (DESS) Scale 
The DESS Scale is a clinician-rated instrument of 43 items used to evaluate signs and symptoms 
associated with discontinuation or interruption of monoamine reuptake inhibitor treatment. Each 
of the 43 signs and symptoms is assessed and placed in one of the following categories: new 
symptom, old symptom but worse, old symptom but improved, old symptom but unchanged, and 
symptom not present. Each sign and symptom that is placed in the category new symptom or in 
the category old symptom but worse receives 1 point. All other categories receive 0 points. The 
total DESS score is the sum of the number of points, which corresponds to the number of

symptoms rated as either a new symptom or as an old symptom but worse. The score ranges 
from 0 to 43, where higher scores indicate more discontinuation-emergent signs and symptoms.  
The DESS is collected at Week 52/EOT, and Weeks 53, 54 and 55/EOS for subjects who enter 
the withdrawal period. 
5.3.2.3. 
Montgomery-Asberg Depression Rating Scale (MADRS) 
The MADRS is a clinician-rated assessment of the subject’s level of depression. This scale 
contains 10 items that measure apparent and reported sadness, inner tension, reduced sleep and 
appetite, difficulty concentrating, lassitude, inability to feel, and pessimistic and suicidal 
thoughts. Each item is scored in a range of 0 to 6, with higher scores indicating increased 
depressive symptoms. The score for each question will be summed to compute a total score 
ranging from 0 to 60. If the response to any question is missing, the total score will be missing. 
The MADRS is collected at Weeks 24, 52/EOT, and Weeks 53, 54 and 55/EOS for subjects who 
enter the withdrawal period. 
5.3.2.4. 
Hamilton Anxiety Rating Scale (HAM-A) 
The HAM-A is a rating scale developed to quantify the severity of anxiety symptomatology.  It 
consists of 14 items, each defined by a series of symptoms.  The 14 items are: anxious mood, 
tension, fears, insomnia, intellectual, depressed mood, somatic (muscular), somatic (sensory), 
cardiovascular symptoms, respiratory symptoms, gastrointestinal symptoms, genitourinary 
symptoms, autonomic symptoms, and behavior at interview.  Each item is rated on a 5-point 
scale, ranging from 0 (not present) to 4 (severe/disabling).  The score for each question are 
summed to compute a total score ranging from 0 to 56. If the response to any question is missing, 
the total score is missing. A higher score is associated with a greater degree of anxiety.  A score 
of ≥ 14 has been suggested to indicate clinically significant anxiety.  
The HAM-A is collected at Weeks 24, 52/EOT, and Weeks 53, 54 and 55/EOS for subjects who 
enter the withdrawal period.

General Analysis Definition 
6.1.1. Analysis Period and Study Day 
Two scopes of data for a subject are considered in this study. Each scope of data consists of a 
specific portion (subset) of study data for the subject.  
6.1.1.1. 
Open-Label Treatment Period (On Treatment) 
The day of the 1st dose date in the extension study will be denoted as study Day 1. All 
measurements at each visit will be assigned a study day relative to this date. All data collected 
on/after Day 1 for subjects previously randomized to placebo group in core study or on/after the 
extension baseline visit for subjects previously randomized to dasotraline groups and up to Week 
52, including the End-of-treatment/Early Withdrawal visit, will be considered within the open-
label treatment phase. That is to say, the start of the open-label treatment period is defined as 
Day 1 for subjects previously randomized to placebo group and the OL Baseline visit date for 
subjects previously randomized to dasotraline groups; the end of the open-label treatment phase 
is defined as the maximum of the last date of administration of study medication and the 
withdrawal/ completion date.  
The start and end of open-label treatment period are given below: 
 Start of treatment period =  
  = Date of the first study medication administration for subjects previously randomized 
to placebo group 
  = Date of the OL Baseline visit for subjects previously randomized to dasotraline; 
 End of treatment period = maximum of the last date of administration of study 
medication and the withdrawal/ completion date (ie, Week 52/EOT visit date). 
Each subject’s assessment at each visit in pre-treatment and treatment period will be assigned a 
study day with respect to the first dose date in the extension study.   
 Study Day = Assessment date − the first dose date in the extension study + 1; if 
assessment date ≥ the first dose date in the extension study 
 Study Day = Assessment date − the first dose date in the extension study; if assessment 
date < the first dose date in the extension study 
6.1.1.2. 
Withdrawal Period (Off Treatment) 
The withdrawal period will begin with immediately after the last study dose. Study day relative 
to the last study dose date will be denoted as Day 0. The end of the withdrawal period is defined 
as the maximum of last study visit (scheduled or unscheduled) and last phone contact after the

last study dose. If the last study dose date is missing or ‘unconfirmed’ (eg, lost follow-up 
subjects), start and end days relative to the last study dose will be set as missing. 
Each subject’s assessment at each visit (site or phone contact) in the withdrawal period will be 
assigned a study day with respect to start date of the withdrawal period (ie, the last study dose 
date). 
 Study Day = Assessment date − the last dose date  if assessment date ≥ the last dose 
date in the extension study 
6.1.1.3. 
Overall Study Period 
Overall study period is defined as a combination of the open-label treatment period and 
withdrawal period. See Table 3 below for summary of definition of all analysis periods and study

Except for adverse event data, summaries and analyses of all data on OL treatment are based on 
the portion of study data that fall in the open-label treatment period. For adverse events, see 
Section 7.4.2 for how a study subject is considered to be on treatment during the treatment period 
(ie, last study medication administration + 7 days for AE or +14 days for Serious AE).  
6.1.2. Visit Windows 
6.1.2.1. 
Visit Windows for Visits in Open-Label Treatment Period 
While the Time and Events Schedule of the protocol indicates the visit timing and procedures for 
each visit, the timing of a subject’s actual visit timing may not be exactly as per the protocol 
indicated target day/visit window (note that the protocol does not indicate required visit windows, 
but rather provides clear guidance for visit timing).  Consequently, for the purpose of analysis, 
the conventions outlined below will be used to allocate the data collected at each actual visit to a 
planned protocol visit by defining analysis visit windows.

If a subject has 2 or more visits in one analysis visit window (scheduled or unscheduled), the 
visit closest to the target day will be used as the study visit for that analysis visit window. The 
other additional visit(s) in the same analysis visit window will not be included in the by-visit 
descriptive summary analyses.   However, measurements from this/these other additional visit(s) 
will be included in the other safety analyses (eg, Potentially Markedly Abnormal Laboratory 
Values or the worst case analysis) to assure all on-treatment measurements are included. If 2 
study visits occur on the same number of days from the target day within the same visit window, 
the later one will be considered as the study visit for that target day.  
Although all (scheduled and unscheduled) visits will be allocated to an analysis visit window, 
only planned protocol visits for each measurement will be included in the by-visit analyses. All 
tables and figures presenting data by visit will present only those timepoints where the applicable 
assessment was scheduled to be collected, unless otherwise noted below.  Unscheduled and early 
termination data will be included for definition of endpoint or overall assessments (eg, the worst 
case analysis for an assessed period).  Data listings will present all data, regardless of scheduled 
and unscheduled visits.

However, measurements from this/these other additional visit(s) may be included in the other 
safety analyses to assure all off-treatment measurements are included. If 2 study visits occur the 
same number of days from the target day within the same visit window, the later one will be 
considered as the study visit for that target day.

6.1.3. Baseline 
Three types of Baseline will be defined: DB Baseline, OL Baseline, and Withdrawal Baseline.  
6.1.3.1. 
DB Baseline  
DB Baseline (ie, Baseline assessment of the double-blind core studies [SEP 360-221, or SEP 
360-321]) is defined as the last assessment made on or before the 1st dose of double-blind study 
medication as described in the SAPs of the core studies. 
6.1.3.2. 
OL Baseline  
Except for height ( for all subjects), demographics (for all subjects) and EDE-Q modified (for 
subjects continued from SEP360-221), unless otherwise specified, based on the protocol of 
SEP360-322 and the schedule of assessment (Attachment 9.1), OL Baseline values are to be 
carried over from W12/Endpoint in the core studies. The OL Baseline is defined as the last 
assessment made on or before Day 1 of the extension study (ie, Baseline assessment in the open-
label study [SEP 360-322] for demographic (for all subjects) and EDE-Q modified (for subjects 
from SEP360-221), and height at the screening and the Endpoint assessment of the double-blind 
studies [SEP 360-221, or SEP 360-321] (for all subjects), otherwise).  
As indicated in the protocol, height at the screening visit in the core studies will be carried over 
as OL Baseline. For operation convenience, the protocol specified that data collected at the EOT 
visit of the core studies are recorded in core studies only and are not to be saved in the clinical 
database of the extension study. Height at OL Baseline visit will be assigned a value per the 
corresponding Study Data Tabulation Model (SDTM) dataset of core studies directly.  
Unless otherwise specified,  at each study visit of study SEP 360-322, data derivation rule and 
missing imputation method for aggregated parameters that involves multiple individual items 
(eg, total score, subscale score, or composite score), are same as the corresponding ones in 
individual core study SAPs.  DB Baseline is defined same as the Baseline in individual core 
study per core study SAPs.  DB Baseline used in the analysis of study SEP 360-322 will be 
extracted from corresponding Analysis Data Model datasets (ADaM) of the core studies directly.

6.1.3.3. 
Withdrawal Baseline  
See Section 6.1.2.2 for the definition of Withdrawal Baseline.  No imputation will be made if the 
Withdrawal Baseline value is missing. 
6.1.4. Endpoint 
6.1.4.1. 
Endpoint 
Endpoint (ie, Week 52 Endpoint) is defined as the last post-OL Baseline assessment during the 
open-label treatment period.  
6.1.4.2. 
Withdrawal Endpoint 
Withdrawal Endpoint is defined as the last non-missing post-withdrawal baseline assessment in 
the withdrawal period (regardless of clinic or non-clinic visits). 
6.1.5. Aggregated Analysis Timepoint 
An aggregated analysis timepoint named as ‘any OL treatment period (treatment emergent)’ will 
be derived for selected safety assessments (eg, the worst case analysis) as below. 
 
Any OL treatment period (treatment emergent): defined as any assessment collected in 
open-label treatment period (see Section 6.1.1.1).   
Specifically, the aggregated analysis timepoint of any OL treatment period (treatment emergent) 
will be applied on the following worst-case analysis:   
 Markedly Abnormal Laboratory Values (MALV) (Section 7.4.3.1, Table 6)  
 Markedly Abnormal Vital Signs (MAVS) (Section 7.4.5.1, Table 9.1)  
 QTc prolongation (Section 7.4.4.1, Table 7)  
 ECG abnormality (Section 7.4.4.1, Table 8).  
 C-SSRS (Section 7.4.7) 
6.1.6. Pooling Strategy for Analysis of Centers 
There will be no pooling of centers in this study. 
6.1.7. Adjustments for Covariates 
Not Applicable. No statistical modeling or inference will be performed, including the ones 
containing baseline as a covariate to adjust baseline.  
6.1.8. Analysis Populations 
The Safety Population: All subjects who receive at least one dose of study medication. The 
safety population mainly is used for the data analyses of the safety data collected through 
Week 52 or during the open-label treatment period.

The Withdrawal Population: The withdrawal population includes all subjects who receive at 
least one dose of study medication, and either early terminate from the study drug during the OL 
treatment period or complete the 52-week OL treatment period, and have at least 1 assessment 
after the last study drug for any evaluation. The withdrawal population is used to summarize the 
safety and effectiveness assessments collected in the withdrawal period. Withdrawal analysis 
will be presented by analysis group.  
The ‘Modified’ Withdrawal Population: all subjects in the withdrawal population plus the 
subjects who either are early terminated during the OL treatment period or complete the 52-week 
OL treatment period and do not enter the withdrawal period, but the last study dose dates are at 
least 2 days  prior to their last study visit. The modified withdrawal population will be only used 
for summary of adverse event data which could be retrospectively collected. 
 
6.1.9. Analysis Group and Analysis Subgroup 
For all subjects in Study 360-322, summary tables, wherever applicable, will be presented by 
analysis group per subject’s previous participation in core studies (ie, subjects previously 
randomized to dasotraline, subjects previously randomized to placebo, all subjects combined) as 
described as below  
 Pbo-Das: Subjects previously randomized to placebo in studies SEP360-221 or SEP360-
321 
 Das-Das: Subjects previously randomized to dasotraline group in studies SEP360-221 or 
SEP360-321   
 All-Das: all subjects combined 
For subjects continued from Study SEP360-221, analyses per selected data may be conducted as 
needed; summary of these analyses will be presented per subject’s previous participation in study 
SEP360-221 as described below(hereafter, referred as ‘Analysis Subgroup A’):  
 Pbo-Das: previously randomized to placebo  
 Das-Das: previously randomized to dasotraline 4–8 mg/day   
 221-Das: all subjects continued from study SEP360-221 
For subjects continued from Study SEP360-321, analyses per selected data may be conducted as

 321-Das: subjects continued from study SEP360-321 
Subjects in Study SEP360-322 may be further grouped and presented according to their 
predominant dose (alternatively, modal dose, see Section 6.1.10) and the maximum dose during 
the open-label treatment period as below, as needed.  Hereafter, analysis subgroup based on the 
modal dose will be referred as ‘Analysis Subgroup C’ and analysis subgroup based on the 
maximum dose will be referred as ‘Analysis Subgroup D’. 
   Analysis Subgroup C 
 Das4: subjects with modal dose of dasotraline 4 mg/day 
 Das6: subjects with modal dose of dasotraline 6 mg/day  
 Das8: subjects with modal dose of dasotraline 8 mg/day 
 All Das: all subjects combined 
   Analysis Subgroup D 
 Das4: subjects with maximum dose of dasotraline 4 mg/day 
 Das6: subjects with maximum dose of dasotraline 6 mg/day  
 Das8: subjects with maximum dose of dasotraline 8 mg/day 
 All Das: all subjects combined 
 
For limited analyses, wherever applicable, results may be presented by modal dose group and 
maximum dose group as needed. 
6.1.10. 
Average Dose, Predominant/Modal Dose, Maximum Dose 
The predominant dose (or, equivalently, modal dose, used interchangeably hereafter in this 
document) duration in the open-label treatment period is defined as the dasotraline dose to which 
the subject was exposed for the greatest duration during the treatment period. If a subject has 2 or 
more doses with the great duration, the one with higher dosage will be selected as predominant 
treatment. 
The average total daily dose during the open-label treatment phase will be calculated as the sum 
of the total daily dose divided the treatment duration (see Section 7.1.5.1). The average total 
daily dose during a visit period is defined in a similar way. 
For any study visit , if medication kit usage information is incomplete (ie, meet one of following 
conditions: any dispensed medication kit at the visit has missing number of tables returned, or 
has missing dosing start or ending date), average total daily dose at the visit will not be derived 
and will be set as missing.  For an assessment period that involves multiple study visits (eg, the 
open-label treatment period), if at some visit(s) the drug usage information is incomplete, then 


Statistical Analysis Plan                                                                                                     Sunovion Pharmaceuticals

                                                                                                                                                                         SEP360-
322 
Final Version 1.0 
29 
 
the other visits with complete information of kit usage will be used to derive the average daily 
dose, predominant dose, and maximum dose,  accordingly.  
 
6.1.11. 
Handling of Dropouts or Missing Data  
6.1.11.1. Unknown or Unconfirmed Last Study Dose Date  
If the end date of the medication intake is unknown or ‘unconfirmed’ (including but not limited 
to, eg, subject is lost to follow-up),  it will be imputed as the earlier date of the disposition date 
(ie, date of the last contact with subject) and 7 days from the date of the last medication kit  
dispensed if the last contact visit is either V1E (OL baseline), or V2E (Week 2), and 14 days 
from the date of the last medication kit dispensed if the last contact visit  is V3E (Week 4) or 
after.  
6.1.11.2. Composite Score 
Unless otherwise specified, any individual missing item in any scale won’t be imputed. When 
calculating a total score, subscale score, composite score, or any assessment with more than one 
item (e.g. EDE-Q modified global score and 3 subscale scores, SDS total score and subscale 
scores, MADRS total score, HAM-A total score, CSSA total score, DESS total score), if one or 
more items are missing at a visit, then the associated score (ie, total score or subscale score) will 
be set to missing.   
Since a vendor generates for the SF-12, two component scores and subdomain scores using 
standard software, missing data is imputed by default algorithm provided by the vendor, which is 
provided on Attachment 9.2. 
For analyses of the change from baseline for a given effectiveness parameter, only subjects who 
have both baseline and at least one post-baseline measurement are included.  
6.1.11.3. Incomplete/Missing Dates 
6.1.11.3.1. 
Start/End Dates for Adverse Event 
Treatment-emergent adverse events (TEAEs) are those reported adverse events with an onset 
date on or after the first day of the open-label treatment period (See Section 6.1.1.1 for definition 
of the OL treatment period)), through 7 days after study drug discontinuation (14 days for serious 
adverse events and deaths). 
A conservative approach will be used to handle the missing dates for AE onset date and end date 
to identify the treatment-emergent AE (ie, if the available incomplete date cannot determine 
treatment emergent status, the AE will be considered as a treatment-emergent AE).  No 
imputation is to be done to calculate AE duration.

322 
Final Version 1.0 
30 
 
6.1.11.3.2. 
Start/End Dates for Prior/Concomitant Medication 
Partial dates of non-study medication start/end date need to be imputed in order to classify the 
medications as prior or concomitant medications, or post-treatment medication (ie, medication 
initiated after the last dose of study medication). A conservative approach will be used to handle 
the incomplete date(s) for medication start/end date (ie, if the available incomplete date(s) cannot 
determine the concomitant relationship relative to the open-label treatment phase, the medication 
is considered as a concomitant medication).  
6.1.12. 
Subgroup Analysis  
For a limited number of descriptive analyses, data will be presented for analysis group by 
subgroup below as needed:  
 Age group at OL Baseline (years): “< 40 years”, “≥ 40 years”  
 Gender: Male, Female 
 Race: White, Non-white 
 BMI at OL Baseline: Non-obese (ie, Normal & Overweight), Obese class I/II, Obese 
class III 
6.1.13. 
BMI (kg/m2)  
BMI is calculated at each visit using the following formula:  
         BMI = weight (kg)/(height(m)*height(m)) 
Height is per measurement at Screening visit in core studies.  
 
6.1.14. 
EDE-QM Items 4, 5, and 6  
EDE-QM items 4, 5, and 6 are expected to collect numeric type of data. Due to the data fields 
were set as character type in clinical database, total 11 records (6 cases for item 4, 3 cases for 
item 5, and 2 cases for item 6), which were collected at early stage of the study, had a range type 
of data   (ie, 1-2, 8-10 etc.) instead of a single integer value. For such cases, the higher value (ie, 
the worse value) are to be used in EDE-QM related summary analyses (eg, mean actual value 
and change from baseline). In addition, for a few records with character value of 
‘NO’,’NONE’,’NA’, and ‘N/A’, zero will be used instead in terms of analysis purpose. The 
original data will be displayed in data listing.

 Methods of Analysis  
6.2.1 General Methodology 
All statistical inference analyses will be performed with 2-sided tests at a significance level of 
0.05, and 2-sided 95% confidence intervals (CI) will be calculated whenever appropriate. All 
data will be summarized by analysis group (or analysis subgroup) and visit as appropriate. All 
subject data will be presented in data listings by subject. 
6.2.2 Statistical Hypotheses for Trial Objectives 
Because of the nature of an open-labeled study, no hypotheses are planned and to be tested. 
6.2.3 Interim Analysis 
One interim analysis was planned to support regulatory filing of BED NDA submission and a 
separate SAP was developed for the interim analysis. 
6.2.4 Data Monitoring  
Data and Safety Monitoring Board (DSMB) meetings are planned to be held at regular intervals. 
Data to be presented to the DSMB are described in its charter.

Statistical Analyses 
All analyses and summaries will be produced using SAS® version 9.3 (or higher) for windows. 
Unless otherwise specified, continuous variables will be summarized with descriptive statistics 
including: the number of observations (n), mean, standard deviation (SD), median, range 
(minimum and maximum values). For change from baseline, 95% CI will be calculated 
whenever appropriate. All categorical data will be presented using frequency counts and 
percentages. Shift tables will be produced for some assessments that contain counts and 
percentages of subjects in each cross-classification level of baseline versus post-baseline 
assessment. The by-visit summary of continuous and categorical data will be displayed at 
protocol planned visits (weeks) and endpoint. Data for unscheduled assessments will be included 
when determining baseline values, selecting worst result for shift analyses, and for summary of 
normal/abnormal values. The listings will include all enrolled subjects in the database. In 
general, the subject listings will be sorted by analysis group, subject number and assessment visit 
and date (and time, if applicable).

Kaplan-Meier plot of the time to early discontinuation will be presented by analysis group and 
subgroup. 
7.1.3. Treatment Compliance 
At each post OL-baseline (Weeks 2 – 52) visit, prior to dispensing study medication, previously 
dispensed study medication will be retrieved and assessed by tablet count.  Compliance in the 
open-label treatment phase will be calculated for each post-OL baseline visit and overall as 
follows: 
 Percent compliance = (number of tablets taken / number of tablets should have taken) x 
100. 
 Number of tablets taken = number of tablets dispensed – number of tablets returned. 
 Number of tablets should have taken = (number of tablets supposed to take in a day) x 
(number of exposure days). 
 Number of exposure days = last dose date – first dose date + 1.

For any study visit, if medication kit usage information is incomplete (ie, meet one of following 
conditions: any dispensed medication kit at the visit has missing number of tables returned, or 
has missing dosing start or ending date), compliance rate at the visit will not be derived and will 
be set as missing.   
For an assessment period that involves multiple study visits (ie, the open-label treatment period), 
if at some visit(s) the drug usage information is incomplete, then the other visits with complete 
information of kit usage will be used to derive the compliance rate. Number and proportion of 
medication kits with incomplete usage information at each dispensed visit and the overall open-
label treatment period will be summarized by treatment for categories below. 
 incomplete kit usage of Dasotraline 4 mg kit 
 incomplete kit usage of Dasotraline 6 mg kit 
 incomplete kit usage of Dasotraline 8 mg kit 
 incomplete kit usage of any Dasotraline kit 
Specifically, for each subject, overall rate (percentage) of medication kits with incomplete usage 
information during the open-label treatment period will be calculated as the total number of 
medication kits with incomplete usage information divided by total number of medication kits 
dispensed in the treatment period. Summary statistics (n, mean, median, range) of overall rate of 
incomplete medication kit usage will be presented by treatment group.  
In addition, number and percentage of subjects with at least one of incomplete medication kit 
usage information for each dispensed visit and the number and percentage of subjects for 
categories below for the overall open-label treatment period will be summarized by treatment 
group. 
 With <=4 incomplete kit usage 
− With 1 incomplete kit usage ONLY,  
− With 2 incomplete kit usage ONLY,  
− With 3 incomplete kit usage ONLY,  
− With 4 incomplete kit usage ONLY,  
 With 5-12 incomplete kit usage 
 With >=13 incomplete kit usage 
                  
 Missing at 1 study visit only; 
 Missing at 2 study visits only; 
 Missing at 3 study visits only;

 Missing at >=4 visits 
 
Non-compliance is defined as less than 75% or more than 125% non-missing compliance with 
the study medication. Subjects with missing compliance will not be classified as non-compliant.  
Descriptive summary statistics (N, mean, median, and range) will be provided by analysis group 
for percent compliance by study visit and overall open-label treatment period. In addition, the 
number and percentage of subjects in the categories of the following variables will also be 
summarized by analysis group for open-label treatment period: 
 Compliant;  
 Non-compliant (<75% or >125%); 
 Non-compliant: <75%;  
 Non-complaint: >125%. 
 
7.1.4. Extent of Exposure 
Treatment duration is defined as the amount of elapsed time between the first and the last day 
that study medication was taken (inclusive). It will be calculated (in days) in terms of the 
difference in relative study days between the last and first dose of study medication, plus one 
day. See Section 6.1.11.1 for imputation rule if the end date of the medication intake is unknown 
or ‘unconfirmed’.   
Descriptive statistics (N, mean, standard deviation, median, and range) will be presented by 
analysis group and analysis subgroup for treatment duration. Number of subjects with duration in 
each of following categories (days): ≥ 1, ≥ 14, ≥ 28,  ≥ 56, ≥84, ≥112, ≥140, ≥168, ≥183, ≥196,  
≥252,  ≥308, and ≥364; 1-13, 14-27, 28-55, 56-83, 84-111, 112-139,140-167,168-195, 196-251, 
252-307, 308-363, ≥364 days will also be presented. Return of the blister card at any given visit 
is not a prerequisite for inclusion in exposure summary statistics if corresponding dose start and 
end dates are reported. 
7.1.5. Study Medication and Concomitant Medications 
7.1.5.1. 
Study Medication 
Descriptive summary statistics (N, mean, median) for the mean daily dose will be provided by 
analysis group at each post-baseline visit, endpoint, and overall treatment period.  Mean daily 
dose for an assessed period (eg, overall treatment period) will be calculated as the sum of the 
total daily dose divided by the total exposure (ie, last dose day – first dose day+1) in the assessed 
period. 
In addition, frequency distribution of the following dose information will be summarized:

 predominant dose(ie, modal dose) during the open-label treatment period 
 maximum daily dose during the open-label treatment period  
See Section 6.1.10 for definition of the predominant daily dose during the OL treatment period. 
In addition, frequency distribution of the all dispensed medication (regardless the kit return 
status) by study visit and number and percentage of subjects who have modified the dosing 
schedule since last visit will be summarized by visit.  
Return of the blister card at any given visit is not a prerequisite for inclusion in average daily 
dose summary statistics or predominant dose summary statistics if corresponding dose start and 
end dates and amount are reported. 
7.1.5.2. 
Concomitant Medications 
Concomitant medications during the open-label treatment period (see Section 6.1.1.1) (ie, 
medications taken during the OL treatment period) are coded using World Health Organization 
(WHO) Drug Dictionary and Anatomical Therapeutic Chemical (ATC) codes.  
Number and percentage of subjects taking concomitant medications will be provided by level 3 
ATC classification and preferred name by analysis group based on the safety population. Since 
medications are coded to ATC classification by indication, preferred names may appear under 
multiple ATC classifications. Concomitant medications started prior to and on/after the first day 
of the open-label treatment period will be summarized separately in a similar way.  
Number and percentage of subjects taking medications after last dose of study drug will be 
summarized based on the withdrawal population.  
 Summary of concomitant usage of sleep aids 
As specified in the study protocol, during the course of the study, subjects are permitted to 
receive sleep aids with some restrictions. The full list of sleep aids used in the study will be 
obtained through medical review prior to the final database lock and the definition of sleep aids 
is provided in Attachment 9.6. The number and percentage of subjects receiving any sleep aid 
during the open-label treatment period will be summarized by preferred term based on the Safety 
population. In addition, percentage of subjects with usage of sleep aids over time will be 
presented graphically by study day, where the percentage is calculated as number of subjects 
with usage of any sleep aid on the day divided by number of subjects remaining on the treatment 
period at that time point. 
All medication data will be included in the prior and concomitant medication listing. 
7.1.6. Psychiatric History and Medical History Prior to DB Phase of Core Study 
Psychiatric history and medical history data will be extracted from the corresponding ADaM 
datasets of core studies directly. The number and percentage of subjects with medical pre-

condition will be summarized by system organ class (SOC) and preferred term for each analysis 
group. 
Psychiatric history information prior to DB phase of core studies will be summarized in a same 
way as for core studies by analysis group. See Section 7.1.2 of SEP360-221 and SEP360-321 
SAP for details. It should be noted that at study level, study SEP360-321 was coded using 
MedDRA 19.0 while study SEP360-221 was coded using MedDRA 18.0. For table summary of 
study SEP360-322, medical history will be summarized based on MedDRA Version 19.0 (ie, 
corresponding data from study SEP360-221 will be re-coded at programming level and summary 
output will be generated accordingly). 
7.1.7. Psychotherapy 
A listing of CRF collected psychotherapy will be provided for all safety subjects. 
 
7.1.8. Protocol Deviations 
Protocol deviations will be collected during monitoring visits. Protocol deviations will be placed 
into the following categories: concomitant medications, dosing, enrollment criteria, laboratory, 
non-compliance, visit schedule, visit/procedure requirement, and other. Each instance of a 
protocol deviation will be reviewed and determined to be major or minor prior to the final 
database lock.  
A summary of  protocol deviations will be provided as the number (%) of subjects with at least 
one protocol major deviation and the number (%) of subjects with a major deviation in each 
category for the safety population. A listing will be provided containing all protocol deviations.

7.2.2. Analysis Methods 
No inferential statistics on effectiveness will be presented. For all continuous effectiveness 
assessments, descriptive summary statistics (N, mean, standard deviation, median, range, and a 
95% confidence interval) will be presented by analysis group, at DB baseline, OL baseline, each 
of post-OL visit, and endpoint in the open-label treatment period. All analyses for the scheduled 
assessments will be based on observed cases (OC). In addition, for all effectiveness evaluations, 
changes from DB baseline and changes from OL baseline will be presented in a similar way 
using summary statistics as described above.  
In addition, the number and percentage of subjects in the following categories for the number of 
days of overeating episodes per Item 6 of EDE-Q Modified will be summarized by analysis 
group and at DB Baseline (for subjects from SEP360-321 only) or DB Screening (for subjects 
from SEP360-221 only), OL Baseline, post-OL Baseline visit, and endpoint: 
 0 day  
 1 day  
 >1 to ≤4 days  
 >4 to ≤8 days  
 >8 to ≤12 days  
 >12 to ≤ 20 days  
 >20 days  
Frequency distribution of BE-CGI-S score over time will be summarized similarly. Plots of the 
mean actual value, mean change from DB Baseline as well as mean change from OL Baseline in 
all effectiveness assessments over time by analysis group will be presented for the safety 
population.

Safety  
7.4.1. Analysis Specifications 
All safety analyses and summaries will be based on the safety analysis population. 
Unless otherwise specified, safety data will be presented separately by analysis group for the 
open-label treatment period (for data collected up to the end of open-label treatment period) and 
withdrawal period (for data collected during the withdrawal period), as appropriate. The CSSA 
and DESS, which are used to assess physical dependence and withdrawal symptoms, are 
collected only at the Week 52/EOT and in the withdrawal period; all other safety data are to be

collected in both treatment period and withdrawal period and will be presented by analysis group 
for the open-label treatment period and withdrawal period, separately, as appropriate. 
For continuous data collected in the OL treatment period, actual observed value and change form 
baseline will be summarized using descriptive statistics (N, mean, standard deviation [SD], 
median, range, 95% confidence interval [CI] as needed). Where changes are reported, the 
reference will be to “DB Baseline”. Where relevant, changes from “OL Baseline” will also be 
reported.  
For continuous data collected in the withdrawal period, the actual value, changes from DB and 
OL baseline (when applicable), and change from withdrawal baseline will be summarized by 
analysis group at study visits (ie, DB Baseline, OL Baseline, Withdrawal Baseline,  and other 
post-withdrawal baseline visits and  withdrawal endpoint). 
There will be no imputation of missing values for clinical laboratory test results, vital sign 
measurements, and ECG evaluations in the by-visit analyses. All analyses of safety data are 
descriptive. No inferential analyses of safety data are performed. 
 
7.4.2. Adverse Events 
All AEs are coded using Medical Dictionary for Regulatory Activities (MedDRA) version 19.0 
or higher. 
Treatment-Emergent Adverse Event (TEAE) 
Treatment-emergent adverse events (TEAEs) are those reported adverse events with onset data 
on or after the first day of the open-label treatment period through 7 days after study drug 
discontinuation (14 days for serious adverse events and deaths). The start of the open-label 
treatment period is defined as Day 1 for subjects previously randomized to placebo group and the 
OL Baseline visit date for subjects previously randomized to dasotraline groups. 
AEs with a start date prior to the first day of the OL treatment period which are reported to have 
an increase in intensity, or which are reported to have a attribution in relationship to study 
medication (ie, attribution to possible related, probably related, related) after the first day of the 
OL treatment period are considered as TEAEs. 
Discontinuation-emergent adverse events (DEAEs) are defined as AEs which have an onset after 
the last dose date of study drug through the Week 55 visit (ie, the last study visit in the 
withdrawal period). 
Table summary of AEs will be limited to TEAEs and DEAEs. All AE data will be displayed in 
data listings. For the sake of simplicity, hereafter TEAE is referred to as AE.  
The overall incidence (ie, number and percent of subjects with one or more AE in each category) 
of AEs, serious AEs, deaths, AEs leading to discontinuation, study drug-related AEs, study 
drug-related AEs leading to discontinuation, serious AEs leading to discontinuation, and serious

study drug-related AEs, and serious study drug-related AEs leading to discontinuation will be 
summarized by analysis group. 
The AEs also will be summarized by system organ class (SOC) and preferred term (PT) by 
presenting the number and percentage of subjects with each AE category. The incidence of AEs 
(by preferred term, grouped by SOC, and presented by analysis group) will also be summarized 
by severity, by the relationship to study medication, by the action taken regarding the study 
medication, as well as by the outcome. If a subject has the same AE on multiple occasions, the 
highest severity (severe, moderate, mild) recorded for the event and the highest drug relationship 
(unrelated, unlikely to be related, possibly related, probably related, and definitely related) will 
be presented, respectively. The relationship to study medication will be presented by 2 categories: 
related (which includes possibly related, probably related, and related, as determined by 
investigators), and not related (which includes unrelated and unlikely to be related, as determined 
by investigators). Furthermore, for AE summary by SOC and PT or by PT only, the following 
combined preferred terms will be summarized as well:  
 
Insomnia: Insomnia, Initial insomnia, Middle insomnia, Terminal insomnia 
 
Hallucination:  Hallucination; Hallucination, auditory; Hallucination, gustatory; 
Hallucination, olfactory; Hallucination, synaesthetic; Hallucination, tactile; Hallucination, 
visual; Hallucinations, mixed; Hypnagogic hallucination; Hypnopompic hallucination; 
Somatic hallucination. 
A Kaplan-Meier plot of the time to the first onset of treatment emergent insomnia (combined 
term) during the extension study will be presented by analysis group. Time to the first onset (in 
days) is defined as the earliest onset date of insomnia – start date of OL treatment period + 1. 
Subjects who do not experience any insomnia on or before the last dose date will be censored on 
the day of last dose.  
Prevalence rate of insomnia (combined term) at a study day in the open-label treatment period is 
defined as number of subjects experiencing insomnia on the day divided by number of subjects 
remaining on open-label study treatment period at that time point. It is notable that subjects may 
experience multiple insomnia episodes during the study. Prevalence rate over time will be 
summarized and presented graphically by analysis group. 
     AE maximum relationship  
Each AE will be classified as ‘related’, ‘not related’, and ‘not specified’. TEAEs with a missing 
AE relationship will be classified as ‘not specified’. AE summary by the relationship to the study 
medication will be based on the highest relationship within an SOC and PT. Response values will 
be ranked in order from minimum to maximum as ‘not specified’ < ‘not related’ < ‘related’. 
     AE maximum severity

Final Version 1.0 
41 
 
AEs with a missing severity will be classified as ‘not specified’. AE summary by the severity 
will be based on the maximum severity within an SOC and PT. Response severity values will be 
ranked in order from minimum to maximum as ‘not specified’ < ‘mild’ < ‘moderate’ < ‘severe’. 
     AE maximum action taken 
AEs with a missing action taken will be classified as ‘unknown’. AE summary by the action 
taken will be based on the maximum action taken within an SOC and PT. Response action values 
will be ranked in order from minimum to maximum as ‘not applicable’< ‘unknown’ < ‘dose 
increased’ < ‘unchanged’< ‘dose reduced’ < ’drug interrupted’< ’drug withdrawn’. 
     AE maximum outcome  
AEs with a missing outcome will be classified as ‘unknown’’. AE summary by the outcome will 
be based on the maximum outcome within an SOC and PT. Response outcome values will be 
ranked in order from minimum to maximum as ‘unknown’ < ‘recovered/resolved’ < 
‘recovered/resolved with sequelae’ < ‘recovering/resolving’ < ‘not recovered/not resolved’< 
‘fatal’.

arrhythmias, combined insomnia, psychosis, mania, suicide and self-injury, spontaneous abortion 
/miscarriage, drug abuse and dependence,  drug withdrawal, and potential drug abuse,  are 
exactly same as what were defined in the ISAP, since their definitions are either directly based 
on standard SMQs or from other standard terms.  
For other AESI categories, including vital signs-related AEs, weight-related AEs, metabolic-
related (excluding weight) related AEs, and neuropsychiatric AEs, their AE preferred terms are 
determined and verified by medical review of coded AE terms during data review and finalized 
prior to the final database lock.  Definitions of these AESIs were obtained per medical review 
from the accumulative database of dasotraline clinical program. Since more data are obtained 
from study SEP360-322 after the BED NDA submission, additional AE preferred terms might be 
identified and added to preferred lists  of definition. AE preferred terms that had been already 
identified in ISS ISAP of BED NDA will be kept as they are.  
Except of category of drug withdrawal related AEs, the incidence of TEAEs with special interest 
by AESI category and PT will be summarized by analysis group, by severity, by the action taken 
regarding the study medication, as well as by the outcome based on the safety population. For 
“Spontaneous abortion /miscarriage” related AEs, the incidence will calculated based on the 
number of female subjects in each analysis group as denominator.  
Listings will also be generated for deaths, SAEs, AESI, and discontinuations due to AEs. All 
adverse events regardless of treatment emergent status will be provided in the AE data listing. 
 
 
AEs by Exposure  
The TEAEs will be summarized by exposure to study drug using time intervals beginning with 
the earliest concurrent exposure to study drug for following AE summary as needed. 
Denominators for exposure intervals will be based on the number of subjects who were exposed 
as of the first day of the interval; for cases where events meet the treatment-emergent definition 
but start after the last dose, the exposure interval for the event will be considered the interval of 
the last day of exposure to study medication. 
 AEs by SOC and PT, Serious AEs by SOC and PT, and AEs leading to discontinuation 
by SOC and PT (sorted alphabetically by SOC and PT within SOC). 
 AEs by PT, AEs with special interest by PT (sorted by descending order per frequency 
count) 
Exposure categories to be summarized are given below: 
 Exposure categories : 1-13 days, 14-27 days, 28-83 days, 84-167 days, ≥168 days.  
AEs by Subgroup  
The TEAEs will be summarized by SOC, PT for subgroups (see Section 6.1.12) below:

Discontinuation-Emergent Adverse Event (DEAE) (ie, AEs Onset After Last Study Dose) 
All summary of DEAEs will be based on a ‘modified’ withdrawal population (see Section 6.1.8), 
which includes all subjects in the withdrawal population plus the subjects who do not enter 
withdrawal period, but their last study dose dates are at least 2 days earlier than their last study 
visit (ie, Week 52/EOT visit). The rationale of defining ‘modified’ withdrawal population is that 
the AE information after the last study dose is expected to be continuously collected till the last 
study visit    
The overall incidence of DEAEs and serious DEAEs will be summarized by analysis group. The 
DEAEs also will be summarized by SOC and PT, and by PT of each analysis group. 
In addition, incidence of DEAEs by SOC and PT will be also summarized using time intervals 
beginning with the earliest AE concurrent withdrawal duration in the withdrawal period, where 
denominators in percentage calculation for withdrawal duration intervals (in days) will be based 
on the number of subjects whose withdrawal duration are no less than the first day of the 
interval. Withdrawal duration (in days) will be derived as the last withdrawal visit date minus the 
last dose date +1 and withdrawal duration categories to be assessed are 1-7 days, 8-14 days, and 
≥ 15 days.  
7.4.3. Laboratory Measurements 
Laboratory data will be summarized for each laboratory test listed in Attachment 9.4.1. 
7.4.3.1. 
Treatment Period 
Descriptive statistics (N, mean, standard deviation, median, and range) will be reported for each 
continuous laboratory analyte at DB baseline, OL baseline, each post-OL baseline time point, 
and endpoint for observed actual value as well as change from DB baseline and OL baseline, 
respectively. Categorical results (eg, urinalysis tests) will be summarized at DB baseline, OL 
baseline, each post-OL baseline visit, and endpoint by analysis group using frequency and 
percentage. All lab values will be presented in the data listings. 
Results for glucose and lipid tests (HDL cholesterol, LDL cholesterol, total cholesterol, and 
triglycerides) will be presented separately by fasting status, which includes fasting only and 
overall (fasting, non-fasting, or unknown).   
The normal reference ranges for laboratory tests will be used to determine whether the laboratory 
test value is below, within, or above the normal range. Shifts from DB baseline and shift from

with laboratory test values below, within, and above the normal range. Criteria for Markedly 
Abnormal Laboratory Values (MALV) per International System of Units (SI) unit of selected 
laboratory parameters can be found in Table 6. Equivalent MALV criteria for conventional unit 
are provided in Attachment 9.4.2. The criterion of MALV is satisfied if a value falls into the 
markedly abnormal range at an assessed visit or if subjects have experienced at least once 
MALV in the open-label treatment period. The number and percentage of subjects with a 
particular MALV at each OL visit, endpoint, and during the open-label treatment period 
(treatment emergent, up to and including endpoint), will be presented by analysis group.

outcomes, which have binary responses (yes/no), will be re-ordered and numbered to facilitate 
the further definitions of the composite endpoint and comparative endpoint of C-SSRS as below. 
Category 1 – Wish to be Dead 
Category 2 – Non-specific Active Suicidal Thoughts 
Category 3 – Active Suicidal Ideation with Any Methods (Not Plan) without Intent to Act 
Category 4 – Active Suicidal Ideation with Some Intent to Act, without Specific Plan 
Category 5 – Active Suicidal Ideation with Specific Plan and Intent 
 
Category 6 – Preparatory Acts or Behavior 
Category 7 – Aborted Attempt 
Category 8 – Interrupted Attempt 
Category 9 – Actual Attempt  
Category 10 – Completed Suicide 
Category 11– Self-injurious behavior without suicidal intent 
Unless otherwise specified, C-SSRS table outputs will be presented by analysis group for one 
analysis time point ‘Any extension (treatment emergent)’, whose definition is given in Table 10.  
The analysis time point is applied to suicidal ideation score and ideation intensity total score.

 emergence of serious suicidal ideation,  
 worsening of suicidal ideation,  
 emergence of suicidal behavior, 
 emergence of suicidality 
Shifts from DB baseline and OL baseline to any post-OL baseline visit (ie, the worst case) in 
suicidal ideation score will be presented by analysis group, to show the percentage of subjects 
with values 0 (’No ideation present’) to 5 (’Active ideation with plan and intent’). Descriptive 
statistics (N, mean, standard deviation, median, and range) will be reported for Ideation intensity 
total score at DB baseline, OL baseline, each post-OL baseline visit, and endpoint for observed 
value as well as change from DB and OL baseline. Data collected on actual suicide attempts 
(lethality of actual attempts and potential lethality of attempts) will be presented in a data listing.  
All summaries pertaining to the C-SSRS will be based on subjects in the Safety population.

Abuse Potential Monitoring Plan (APMP) 
The Abuse Potential Monitoring Plan (APMP) for dasotraline has been designed to detect 
potential abuse of the compound and to more closely monitor AEs consistent with the 
pharmacology. The plan detects irregularities in the handling of dasotraline in clinical trials and

identifies the misuse of dasotraline or other psychoactive substances. Moreover, the APMP 
provides a process by which events subject to additional monitoring are identified, processed, 
and reviewed. Events subject to additional monitoring are identified based on the pharmacology 
of dasotraline, as well as adverse event profiles of compounds with similar mechanisms of 
action. 
APMP results will be provided by sites before DBL and provided in a listing. 
7.4.8.3.1. Medication Handling Irregularities 
Medication handling irregularities will be summarized using the following categories: 
 Drug accounting errors, not involving suspected abuse or diversion by subject 
 Non-compliance with study procedures, not involving suspected abuse or diversion by 
subject 
 Other cases not involving suspected abuse or diversion by subject 
 Suspected or known abuse or diversion of study drug 
 Suspected abuse (nonmedical use) of alcohol, illicit substances, OTC drugs or 
prescription drugs obtained outside the study protocol 
Instances that meet the threshold criteria for a medication handling irregularity will be 
summarized descriptively. Both the number of instances and the number (%) of subjects 
experiencing medical drug irregularities will be provided for each category and by analysis 
group. Instances of medication handling irregularity will be listed for all enrolled subjects. 
7.4.8.3.2. Events Subject to Additional Monitoring (ESAMs) 
In addition to monitoring for irregularities in medication handling, AEs that may be suggestive 
of a developing abuse potential, will receive special attention. The adverse experiences or related 
signs and symptoms that will require additional monitoring (ESAMs) are listed in Attachment 
9.5. AEs identified as ESAMs will be summarized by ESAM type and PT by analysis group for 
safety population (OL treatment period) and withdrawal population (withdrawal period), 
respectively.  ESAMs will also be listed for all enrolled subjects.
