1 PROTOCOL SYNOPSIS AND SCHEDULE OF EVALUATIONS 
CLINICAL STUDY SYNOPSIS: Study ITI-007-501 
Title of Study 
A Randomized, Double-blind, Placebo-controlled Multicenter Study to 
Assess the Efficacy and Safety of Lumateperone as Adjunctive Therapy in 
the Treatment of Patients with Major Depressive Disorder. 
Study Centers (Country) 
Approximately 60 study centers (United States and globally).  
Development Phase 
3 
Objectives 
Primary Objective 
• 
To evaluate the efficacy of lumateperone 42 mg administered once 
daily compared with placebo as adjunctive treatment to 
antidepressant therapy in patients with Major Depressive Disorder 
(MDD) who have an inadequate response to ongoing antidepressant 
therapy (ADT) as measured by change from baseline to Day 43 in 
the Montgomery-Åsberg Depression Rating Scale (MADRS) total 
score. 
Key Secondary Efficacy Objective 
• 
To evaluate the efficacy of lumateperone 42 mg administered once 
daily compared with placebo as adjunctive treatment to ADT in 
patients with MDD who have an inadequate response to ongoing 
ADT as measured by change from baseline to Day 43 in the Clinical 
Global Impression Scale-Severity (CGI-S). 
Study Design 
This is an international, multicenter, randomized, double-blind, placebo-
controlled, parallel-group, fixed-dose study in patients with a primary 
diagnosis of MDD according to criteria of the Diagnostic and Statistical 
Manual of Mental Disorders, Fifth Edition (DSM-5) who have an 
inadequate response to ongoing ADT. 
The study will be conducted in three periods:  
• 
Screening Period (up to 2 weeks) during which patient eligibility 
will be assessed; 
• 
Double-blind Treatment Period (6 weeks) in which all patients will 
be randomized to receive placebo or lumateperone 42 mg/day in 1:1 
ratio. 
• 
Safety Follow-up Period (1 week) in which all patients will return 
to the clinic for a safety follow-up visit approximately one week 
after the last dose of study treatment. 
Number of Patients 
Approximately 470 patients (235 per treatment group) are planned to be 
enrolled in the Double-blind Treatment Period. 
Diagnosis and Main Criteria for 
Inclusion and Exclusion 
Main Inclusion Criteria 
Patients will be eligible for study participation if they meet the following 
inclusion criteria: 
1. Provides written informed consent; 
2. Male or female patients between the ages of 18 and 65 years, 
inclusive;

Statistical Methods 
The primary efficacy endpoint will be change from Baseline to Day 43 in 
MADRS total score. Based on the primary hypothetical estimand strategy 
which assumes patients are on study treatment up to the primary time point 
(Day 43), efficacy data collected after discontinuation of study treatment 
(ie, efficacy assessment performed more than 3 days after last dose of study 
treatment) and/or after starting new ADT will be set to missing and will not 
be included in the primary analysis. Instead, these missing data will be 
assumed as missing at random. The primary analysis to estimate and 
compare the treatment effects of lumateperone vs placebo as defined by the 
primary estimand will be performed using a mixed-effects model for 
repeated measures (MMRM) with change from baseline at each study visit 
as the response variable, and treatment group, study site (or pooled site) 
and study visit as factors, baseline MADRS total score as covariate, and 
interaction terms for baseline MADRS total score-by-study visit and 
treatment group-by-study visit. An unstructured covariance matrix will be 
used to model the covariance of within-patient scores. The Kenward-Roger 
approximation will be used to estimate the denominator degrees of 
freedom. Treatment difference will be estimated via contrast based on 
treatment group and treatment group-by-study visit factors. 
The key secondary efficacy parameter will be the change from baseline to 
Day 43 in CGI-S score. The key secondary efficacy parameter will be 
analyzed using a similar MMRM as used for the primary analysis with the 
baseline CGI-S score for the covariate. 
A fixed sequence testing procedure will be used to control the overall 
Type I error of 0.05 with the primary endpoint tested first at the 2-sided 
0.05 level, and if significant, the key secondary endpoint will be tested at 
the 2-sided 0.05 level. 
Primary efficacy analyses will be based on the modified Intent-to-Treat 
(mITT) Population, defined as all randomized patients who received at least 
1 dose of study treatment, have an evaluable baseline assessment of 
MADRS total score, and have at least one evaluable post-baseline, on-
treatment assessment of the MADRS total score (on-treatment MADRS 
assessments are those performed no later than 3 days after the last dose of 
study treatment). 
Key secondary efficacy analyses will also be based on the mITT Population. 
An estimation and comparison of the treatment effects of lumateperone vs 
placebo for the key secondary endpoint are based on the hypothetical 
estimand (similar to that defined for the primary analysis, using assessed 
CGI-S score up to 3 days after last study dose and not including those 
assessed after new ADT). 
All safety parameters will be summarized descriptively. Safety analyses 
will be based on the Safety Population defined as all randomized patients 
who received at least one dose of investigational product.  
Individual plasma concentrations will be listed and summarized by visit. 
Plasma concentrations will be analyzed using a population PK approach. 
The results from the population PK analyses will be presented in a separate 
report. 
Approximately 470 patients will be randomly assigned to 1 of the 2 
treatment groups (lumateperone 42 mg or matching placebo). Assuming a 
common drop-out rate of 20% and a common correlation of 0.7 between 
the repeated measures, the sample size of 235 patients per treatment group 
will provide approximately 90% statistical power for the effect size of 0.33 
(treatment difference of 3.3 and common pooled standard deviation of 10) 
for the primary efficacy endpoint.

4 INTRODUCTION 
Major depressive disorder (MDD) is a serious psychiatric disorder characterized by the presence 
of one or more major depressive episodes (MDE). Major depressive episodes may begin at any 
age; however, the average age of onset is in the mid-20s. The lifetime risk for MDD is estimated 
at 5% to 12% for men and 10% to 25% for women. Depression can have damaging effects on 
health and wellbeing, and leave one at risk for social withdrawal, alcohol abuse, and disrupted 
work, family, and social life (Kupferberg et al, 2016). MDD has a high mortality rate and up to 
15% of patients with severe major depressive episodes die by suicide. In addition, individuals with 
MDD have high medical morbidity and are often plagued with more pain and physical illness than 
the general population. 
Despite a number of approved antidepressants, a substantial percentage of individuals with MDD 
have inadequate response to conventional antidepressants alone or in various combinations (Little, 
2009). In STAR*D (Sequenced Treatment Alternatives to Relieve Depression), the largest 
randomized trial of the treatment of MDD, a representative sample of outpatients with MDD 
received one to four successive acute treatment steps. Those who did not achieve remission at each 
treatment step were able to move to the next step. Only 36.8% of patients achieved remission at 
step 1, the first course of antidepressant treatment (Rush et al, 2005). More than 20% of those who 
failed to improve with the first treatment stopped taking medication, primarily within the first 2 
weeks (Warden, 2007). Depressed patients who have an inadequate response to ADT represent a 
particularly vulnerable, at risk population.  
Lumateperone (trade name CAPLYTA®) was approved by the Food and Drug Administration 
(FDA) on December 20, 2019 under NDA 209500 for the treatment of schizophrenia in adults. 
ITI, the Sponsor, is exploring the utility of lumateperone as adjunctive therapy in the treatment of 
MDD.  
Lumateperone is a novel small molecule therapeutic agent designed specifically to combine 
serotonergic, dopaminergic, and glutamatergic modulation in a dose-dependent manner. 
Lumateperone is a potent serotonin 5-HT2A receptor antagonist with mesolimbic/mesocortical 
selective modulation of phosphoprotein pathways downstream of dopamine receptors, serotonin 
reuptake inhibition, and indirect glutamatergic modulation (Snyder et al, 2015). As a dopamine 
receptor protein phosphorylation modulator, lumateperone has dual properties, acting as post-
synaptic antagonist and as a pre-synaptic partial agonist at dopamine 2 (D2) receptors in vivo, with 
mesolimbic/mesocortical selectivity. Lumateperone also increases the phosphorylation of the 
NR2B, or GluN2B, subunit of N-methyl-D-aspartate channels in extrastriatal dopamine-rich brain 
regions (eg, nucleus accumbens) and indirectly modulates glutamatergic (NMDA and AMPA) 
activity downstream from dopamine 1 (D1) receptor activation.  
As a 5-HT2A receptor antagonist and serotonin reuptake inhibitor, lumateperone is predicted to 
have antidepressant efficacy with fewer side effects than selective serotonin reuptake inhibitors 
(Meltzer et al, 1989). Lumateperone’s indirect glutamatergic modulation in combination with 
serotonin reuptake inhibition may also play a role in antidepressant response. Importantly, 
lumateperone lacks potent off-target interactions that have been associated with side effects of 
other antipsychotic drugs approved as adjunctive treatment of MDD. For example, lumateperone 
shows relatively weak affinity for 5-HT2C and no measurable affinity for H1 or muscarinic

cholinergic receptors, which predict favorable body weight and metabolic profile responses to the 
extent that these receptors mediate such effects. 
Nonclinical data also suggest that lumateperone may have the potential to treat depression (Snyder 
et al, 2015). Antidepressant-like activity of lumateperone was measured using the social defeat 
(resident-intruder) mouse model. Mice exposed to repeated social defeat conditions display a 
reduced amount of time in contact with unfamiliar non-aggressive mice than normal controls. Such 
defeat behavior is reversed by chronic (but not acute) treatment with clinically effective 
antidepressant drugs. In this model, lumateperone 1 mg/kg, administered once daily 
intraperitoneally for 28 days, reversed the defeat behavior, consistent with antidepressant efficacy. 
Brain-receptor target engagement was confirmed in healthy male volunteers in Study ITI-007-003, 
the positron emission tomography (PET) Phase 1 clinical trial (Davis et al, 2015). PET was used 
to determine dopamine D2 receptor, serotonin transporter (SERT), and serotonin 5-HT2A receptor 
occupancy in the brain at various times following single dose oral lumateperone administration. 
Lumateperone rapidly penetrated the brain, showed long-lasting and dose-related occupancy, and 
was generally safe and well-tolerated. Cortical 5-HT2A receptors were shown to be fully occupied 
at the 10 mg dose (>85% occupancy). A dose of lumateperone 40 mg achieved up to 39% striatal 
D2 occupancy (average of 29%) and up to 31% striatal SERT occupancy (average of 22%). 
Together, these data confirm a central mechanism for lumateperone at dopaminergic and 
serotonergic brain targets. 
Clinical data from 3 well-controlled studies in patients with schizophrenia (Studies ITI-007-005, 
ITI-007-301, and ITI-007-302) are consistent with respect to the pharmacological profile and 
prediction for antidepressant effects with favorable safety and tolerability. In addition to improving 
psychotic symptoms, lumateperone also improved symptoms of depression in patients with 
schizophrenia and comorbid depression at baseline. Similar improvements in depression 
symptoms were also seen in a one-year open label study of lumateperone in patients with 
schizophrenia (ITI-007-303). In this study, the favorable safety and tolerability profile was 
sustained.  
Clinical data from 3 well-controlled bipolar depression studies (Studies ITI-007-401, ITI-007-404, 
and ITI-007-402) demonstrated efficacy in bipolar depression and confirmed lumateperone’s 
tolerability and favorable safety profile.  
In Study ITI-007-404, once-daily lumateperone 42 mg met the primary endpoint with statistically 
significant improvement over placebo at Week 6 (study endpoint), as measured by change from 
baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) total score. Lumateperone 
42 mg also met the key secondary endpoint of statistically significant improvement on the Clinical 
Global Impression Scale, Bipolar version, Severity (CGI-BP-S) total score and demonstrated 
statistically significant improvement on the CGI-BP-S depression. 
In Study ITI-007-402, once-daily lumateperone 42 mg adjunctive to lithium or valproate met the 
primary endpoint with statistically significant improvement over placebo at Week 6 (study 
endpoint), as measured by change from baseline in MADRS total score. Lumateperone 42 mg also 
met the key secondary endpoint of statistically significant improvement on the CGI-BP-S 
depression subscale.

In Study ITI-007-401, neither lumateperone dose (28 mg or 42 mg) met the primary endpoint of 
statistical separation from placebo as measured by change from baseline in MADRS total score. 
Patients who completed Study ITI-007-401 were eligible to participate in an optional, 6-month 
open-label extension. On average, patients improved and did not worsen on lumateperone 42 mg 
with respect to their depressive symptoms. 
Safety data from these studies and other trials with lumateperone, which has been administered to 
more than 3300 individuals for up to one year, show lumateperone to be well tolerated across a 
dose range from 0.7 to 126 mg, with a safety profile similar to placebo.  
The purpose of the current study is to confirm the efficacy, safety and tolerability of lumateperone 
as adjunctive therapy for the treatment of patients with MDD. Patients will be monitored carefully 
for their mental health status and general health. Symptoms of depression may or may not improve 
during participation in this study; approximately half of the patients in this study will receive 
placebo. However, the information obtained from this study may help to treat people with 
depression in the future. More detailed information about the known and expected benefits and 
risks and reasonably expected AEs is provided in the current lumateperone Investigator’s 
Brochure.

6 INVESTIGATIONAL PLAN 
6.1 
Overall Study Design and Plan 
Study ITI-007-501 is a Phase 3, randomized, double-blind, placebo-controlled, multicenter study 
to evaluate the efficacy, safety, and tolerability of lumateperone as adjunctive therapy for the 
treatment of patients with MDD. This study will be performed at approximately 60 study centers 
in the United States and globally.  
The study will be conducted as follows: 
• A Screening Period of up to 2 weeks 
• A 6-week Double-blind Treatment Period 
• A 1-week Safety Follow-up (SFU) Period 
The maximum study duration for each patient will be approximately 9 weeks. 
The study design schematic is provided in Figure 6-1. The Schedule of Evaluations is presented in 
Table 1-1. Detailed descriptions of the procedures conducted at each study visit are provided in 
Section 8.5.

Scientific Rationale for Study Design 
6.2.1 
Study Design 
Screening Period (up to 2 Weeks)  
Potential patients will be evaluated during a Screening Period lasting up to 14 days. With approval 
from the Sponsor or designee, short extensions to the Screening Period may be granted in 
exceptional circumstances. After obtaining written informed consent, diagnostic interviews, 
determination of inadequate response to current ADT, and physical examinations will be 
conducted, vital signs and ECGs will be assessed, and blood samples will be collected for 
laboratory assessments. Patients considered potentially eligible will be required to continue their 
current ADT but will be required to discontinue other psychotropic drugs.  
Evaluation of diagnostic validity and eligibility of each patient will be undertaken by the Sponsor 
or designee. 
At Baseline (Visit 2), patients who continue to meet all eligibility criteria will be randomized to 
1 of 2 treatment arms, lumateperone 42 mg or matching placebo, and will enter the 6-week, double-
blind treatment period.  
Double-blind Treatment Period (6 Weeks)  
Patients will self-administer his/her first dose of study treatment on the evening of the Baseline 
visit (Visit 2/Day 1). A single dose will be taken each day in the evening, with or without food, 
for the duration of the 6-week Double-blind Treatment Period. Antidepressant treatment will also 
continue as previously prescribed. The dose and frequency of ADT must not change during the 
Screening Period or for the duration of the Double-blind Treatment Period. 
Patients will attend outpatient study visits on Days 8, 15, 22, 29, 36, and 43. With approval from 
the Sponsor or designee, sites will be permitted to conduct remote visits if a site-based visit is not 
feasible. However, all Screening (Visit 1) and Baseline (Visit 2) assessments must be performed 
in person. 
A patient will be defined as a treatment completer if the patient completes the Double-blind 
Treatment Period (all scheduled visits up to and including Visit 8). Patients who withdraw 
prematurely should be seen for an Early Termination (ET) visit as soon as possible and will also 
be asked to return for a safety follow-up visit approximately one week after Visit 8/ET. 
Safety Follow-up Period (1 Week)  
All patients should return to the clinic for the SFU visit approximately 1 week after Visit 8/ET. 
Any ongoing AEs at the SFU visit must be followed until resolution, until the AE stabilizes, until 
it is determined to be not clinically significant, or until the patient is lost to follow-up.

6.2.2 
Separate Open-label Safety Study  
Patients who complete the 6-week Double-blind Treatment Period, who are considered to be 
appropriate by the Investigator, and who meet eligibility criteria may enroll in the 6-month Open-
label Safety Study at the Visit 8/Week 6 visit. This rollover visit to the Open-label Safety Study at 
Visit 8/Week 6 must be in person. A patient who enters the Open-label Safety Study will not have 
a SFU visit (Visit 9/Week 7). 
6.2.3 
Dose Selection 
Lumateperone 42 mg was selected based on the efficacy seen with this dose in bipolar depression 
studies ITI-007-404 and ITI-007-402. This dose delivers full occupancy of the cortical 5-HT2A 
receptors (>85% occupancy) with modest striatal D2 receptor occupancy and SERT occupancy. 
Data from human PET brain receptor occupancy studies with lumateperone indicate that a dose as 
low as 10 mg is associated with >85% occupancy of cortical 5-HT2A receptors, while the 42-mg 
dose demonstrates approximately 40% striatal D2 receptor occupancy. SERT occupancy has been 
demonstrated to be comparable to D2 receptor occupancy. Moreover, in patients with 
schizophrenia and bipolar depression, once-daily oral administration of lumateperone 42 mg has 
been well tolerated with no dose titration needed and with a safety profile similar to placebo with 
up to 6 weeks treatment duration. Therefore, a fixed-dose design will be employed in this study 
with once daily oral administration of lumateperone 42 mg (or placebo).  
A placebo control group is needed to establish the efficacy of a new indication. The 6-week 
treatment period duration was chosen because it is considered an acceptable period to demonstrate 
efficacy in this patient population. The hypothesis of this study is that lumateperone 42 mg will 
demonstrate efficacy based on a 2-sided test for the treatment of MDD, with statistically significant 
superiority vs placebo on the primary outcome measure: Change from baseline to Day 43 in 
MADRS total score in patients with MDD.

Note: Any other medical condition, or medical conditions that are stable with treatment (eg, 
hypertension, hypercholesterolemia, or thyroid abnormalities) are allowed as long as the 
condition has been stable for at least 3 months prior to Screening (Visit 1); treatments for 
these conditions are documented, kept stable, and are expected to be unchanged during the 
study; and the condition is not thought to affect safe participation in the study or relevant 
study outcomes in the opinion of the Investigator and confirmed by the Sponsor or 
designee. 
 
Other Criteria: 
22. The patient is judged by the Investigator to be inappropriate for the study;  
23. The patient is an employee of the Investigator or study site, or immediate family (ie, spouse, 
parent, child, or sibling, whether biological or legally adopted) of such employees, the 
Investigator, the Sponsor, or contract research organizations (CROs) conducting the study.

Stopping Criteria  
This section describes the patient-level discontinuation or stopping criteria as well as study-
stopping criteria. 
6.4.1 
Discontinuation of Patients from Therapy or Assessment: Patient-level Stopping 
Criteria 
A premature discontinuation will occur when a patient who signed the ICF ceases participation in 
the study, regardless of circumstances, before the completion of all study visits and procedures. 
Patients can be prematurely discontinued from the treatment period for one of the following 
reasons: 
• Death 
• AE 
• Lack of efficacy (patients whose MDD symptoms worsen or are determined by the 
Investigator to not be adequately controlled prior to completing the double-blind treatment 
period may be withdrawn from the study to start appropriate treatment at the Investigator’s 
discretion) 
• Protocol violation 
• Study terminated by Sponsor 
• Site terminated by Sponsor 
• Withdrawal by subject or withdrawal of consent 
• Lost to follow-up (every effort must be made to contact the patient; a certified/traceable 
letter must be sent) 
• Pregnancy 
• Other (such as physician decision, administrative reasons, etc) 
NOTE: If a patient discontinues due to withdrawal of consent and either a concurrent AE was 
reported or concurrent lack of efficacy was documented, the study site should query and confirm 
the primary reason for discontinuation and record the primary reason for discontinuation on the 
electronic case report form (eCRF). 
Patients who discontinue from the study and do not return to the study center for final assessments 
must be requested in writing to return to the study center for a final assessment. A copy of the 
letter, together with the source documentation, will be kept in the Investigator’s files. The reason 
for premature discontinuation from the study will be recorded on the Study Termination Page of 
the eCRF. Study center staff may be contacted by the Sponsor or designee after each premature 
discontinuation to ensure that proper characterization of the reason for discontinuation is captured. 
All patients who prematurely discontinue from the study regardless of cause should be seen for a 
final assessment at an ET Visit. All patients who prematurely discontinue from the study should 
return for the safety follow-up visit

6.4.2 
Study Stopping Criteria 
This study will be regularly monitored for safety and tolerability based on routine review of safety 
data. On a quarterly basis during study conduct, all safety data (adverse events, clinical laboratory 
measures, vital signs, ECGs, and C-SSRS) will be reviewed in a blinded manner. If the Study 
Physician determines at any point during the double-blind treatment period that the risk of study 
continuation outweighs the benefits, a determination to stop the study can occur in conjunction 
with discussions with the Head of Clinical Development or designee, the Head of Drug Safety and 
Pharmacovigilance, and the Chief Medical Officer. 
6.5 
Patient Replacement Procedures 
Patients who prematurely discontinue from the study during the double-blind treatment period will 
not be replaced. 
6.6 
Changes in the Conduct of the Study 
Any amendment to this protocol will be provided by the Sponsor in writing to the Investigator. No 
protocol amendment may be implemented before it has been approved by the IRB/IEC and 
Competent Authorities (if applicable), and the signature page, signed by the Investigator, has been 
received by the Sponsor. If the protocol is amended to eliminate or reduce the risk to patients, the 
amendment may be implemented before IRB/IEC and Competent Authority review and approval. 
However, the IRB/IEC and the Competent Authority must be informed in writing of such an 
amendment, and approval must be obtained within reasonable time limits. Administrative changes, 
such as changes in study personnel, will be specified in the Study Reference Manual. 
Administrative changes will not require a protocol amendment.

One 1×10 strip of lumateperone-matched placebo 
Note: Each card will hold 10 capsules. 
 
7.2.1 
Storage of Study Treatment 
Study treatment must be stored in a secure area, eg, a locked cabinet, protected from moisture, and 
kept at room temperature . Sites must report any temperature excursions as described in the Study 
Reference Manual or contact the Sponsor or its designee for further instructions. Patients will be 
instructed to store the blister card at room temperature at home, out of the reach of children. 
7.2.2 
Study Treatment Accountability 
The Investigator will maintain accurate records of receipt of all study drug, including dates of 
receipt. In addition, accurate records will be kept regarding when and how much study treatment 
is dispensed and used by each patient in the study. Reasons for deviation from the expected 
dispensing regimen must also be recorded. 
At the end of the study, all study treatment must be accounted for. In addition, at the end of the 
study, all unused study treatment and empty study treatment packages should be returned to the 
Sponsor or designee or destroyed, as per instructions provided by the Sponsor. 
7.3 
Method of Assigning Patients to Treatment Groups 
After a patient signs the ICF at Screening (Visit 1), site personnel will register the patient in the 
interactive web response system (IWRS). 
Study treatment will be labeled with medication kit numbers. The IWRS will provide the study 
center with the specific medication kit number(s) for each patient at the time of randomization. 
Unblinded biostatistics personnel not participating in the conduct of the study will generate a 
permuted block randomization schedule using SAS software Version 9.4 or newer for IWRS, 
which will link sequential patient randomization numbers to treatment codes. In the event that the 
blind needs to be broken because of a medical emergency, the Investigator may unblind an 
individual patient’s treatment allocation (Section 7.5). 
Study center personnel will dispense study treatment according to the IWRS instructions. Study 
center personnel will also log onto the IWRS at subsequent visits to obtain a study treatment kit 
number for dispensing study treatment. Study centers will receive the IWRS confirmation 
notifications for each transaction. All notifications are to be maintained with the study source 
documents.

7.4 
Blinding 
The study will be performed in a double-blind manner. All study treatment will be supplied in 
identical treatment cards and packaging, and will be similar in color, smell, taste, and appearance, 
thereby enabling double-blind conditions. 
7.5 
Unblinding 
Unblinding at the study center should be done only in an emergency that requires the study 
treatment to be identified for the medical management of the patient. The Investigator must notify 
the Sponsor or designee immediately and a full written explanation must be provided if the blind 
is broken. Before study treatment is unblinded, every attempt should be made to discuss the case 
with the Sponsor or designee. Breaking the code at the study center will immediately disqualify 
the patient from further participation in the study. 
Treatment codes may be broken by Drug Safety for regulatory reporting purposes. In such cases, 
the study center staff will be kept blinded and the patient will not need to be disqualified from the 
study. 
For IWRS Unblinding 
In an emergency, the Investigator can obtain the treatment assignment of any patient at his/her 
study center through the IWRS. In an emergency, the Investigator will access the IWRS to break 
the blind. 
7.6 
Monitoring Treatment Compliance 
Study treatment adherence will be emphasized at every visit. Study treatment compliance during 
any period will be closely monitored. Compliance is based on the number of capsules prescribed 
and number of capsules taken. At every visit, study staff will count the number of capsules 
remaining in the blister pack. Any irregularities in study treatment adherence should be discussed 
with the patient. All errors in study treatment dispensing or administration must be carefully 
documented. These errors may include providing the wrong dose, not taking the dose as prescribed, 
or losing medication. 
In addition, at every visit, study staff will ask the patient about compliance with prescribed ADT 
dosing regimen.  
Any exceptions to non-compliance due to unusual circumstances should be discussed with the 
Sponsor or designee. 
7.7 
Prior and Concomitant Medications 
Use of all concomitant medications will be recorded in the patient’s eCRF. Drug name and dates 
of administration must be recorded for all prescription drugs, herbal products, vitamins, minerals, 
and over-the-counter medications. Any changes in concomitant medications will also be recorded 
in the patient’s eCRF. Any concomitant medication deemed necessary for the welfare of the patient 
during the study may be given at the discretion of the Investigator, eg, limited, acute prescribed

opioid use. However, it is the responsibility of the Investigator to ensure that complete details 
regarding the medication are recorded in the eCRF. 
7.7.1 
Prior Medications 
Tapering and discontinuation of psychotropic medications, with the exception of the ongoing 
antidepressant, will take place during the Screening Phase lasting up to 2 weeks. A washout is not 
required for non-psychotropic medications; however, certain medications do have stability 
requirements as presented in the eligibility criteria. Medication history, including the use of 
psychotropic medication or of any other medication, should be recorded at Screening (Visit 1). 
Thereafter, any changes in concomitant medications or new medications should be recorded in the 
eCRF.  
7.7.2 
Prohibited Medications 
Use of the following products during the study is prohibited: alcohol, cannabis, illicit drugs, any 
known 5-HT2A receptor antagonist or inverse agonist, any strong cytochrome P450 3A4 inhibitor 
or inducer, or any drugs with known psychotropic properties or any non-psychotropic drugs with 
potential central nervous system effects. 
Patients who have been taking a low dose of quetiapine (< 50 mg) for the treatment of insomnia 
must discontinue quetiapine at the Screening Visit (Visit 1). 
7.7.3 
Rescue Medication 
Medications for the acute treatment of extrapyramidal symptoms and akathisia are allowed.  
Zolpidem may be taken for insomnia, in the evening at bedtime and prior to midnight, but no more 
than 3 times per week during the screening period and the first 2 weeks of the double-blind 
treatment period only (Section 6.3.2, Exclusion 13) for the treatment of insomnia. If zolpidem is 
not available in specific regions, another sedative hypnotic may be approved by the Sponsor or 
designee. 
The date and time of each dose of rescue medication administration as well as the name and dosage 
regimen of the rescue medication must be recorded on the eCRF. 
7.8 
Treatment After Discontinuation 
Patients whose depressive symptoms worsen or are determined by the Investigator not to be 
adequately controlled prior to completing the Double-blind Treatment Period may, at the 
Investigator’s discretion, be discontinued from the Double-blind Treatment Period in order to start 
appropriate treatment. This new treatment will not be provided by the Sponsor. Patients who 
initiate a new treatment during the study must be discontinued from the study and should also 
return for a Safety Follow-up visit. 
All patients who prematurely discontinue from the Double-blind Treatment Period regardless of 
cause should be seen for a final assessment at the ET Visit. All patients who prematurely 
discontinue from the Double-blind Treatment Period should return for the Safety Follow-up visit.

8 EFFICACY, SAFETY AND OTHER ASSESSMENTS 
8.1 
Diagnostic and Other Screening Period Assessments 
8.1.1 MINI International Neuropsychiatric Interview 
To be included in this study, a patient must meet the DSM-5 criteria for diagnosis of Major 
Depressive Disorder, as confirmed by the MINI (7.0.2; 8/8/16 version). The MINI is a validated 
clinical diagnostic tool (Sheehan et al, 1998) that will be used at the Screening visit only and will 
be completed by a Sponsor-approved rater. 
MGH Antidepressant Treatment Response Questionnaire (ATRQ) 
The Massachusetts General Hospital Antidepressant Treatment Response Questionnaire (ATRQ) 
(Chandler et al, 2010) is a clinician-administered scale used to determine treatment resistance in 
Major Depressive Disorder. The scale defines 6 weeks on an adequate dose of antidepressant 
medication as an adequate duration of treatment. It also provides specific operational criteria for 
adequate dosage for each of the most commonly used antidepressants. 
Medical History and Other Information 
Medical history information will be collected at screening and should include demographic 
information (as allowed by local country legislation), current and past medical conditions, and 
current and past medications. Prior to study treatment administration, medical history must be 
documented in the patient’s study chart and also recorded in the appropriate eCRF.  
Patients will be checked for previous participation in an ITI-007 clinical study and for duplicate 
enrollment by study site staff through Verified Clinical Trials (VCT). 
8.1.2 
Eligibility Review Process 
Eligibility of potential patients will be confirmed by the Sponsor or designee through a review of 
screening data, including safety and laboratory assessments, medical and psychiatric history, 
including the ATRQ, and psychiatric status, including DSM-5 diagnosis of MDD, as confirmed 
by the MINI, and MADRS, CGI-S and QIDS-SR-16 scores. Further information regarding the 
eligibility review process and the Pre-Enrollment Eligibility Review (PEER) Form are provided 
in the Study Reference Manual. 
8.1.3 
Patient Placebo Questionnaire and Training 
A brief training module will be provided describing placebo response at Baseline (Visit 2) prior to 
randomization. A placebo response questionnaire will be administered at Baseline (Visit 2) prior 
to randomization to assess the patient’s perception of likelihood their symptoms will improve as 
well as their perception at the end of the study whether they received placebo or active study 
treatment.

8.1.4 
Quick Inventory for Depressive Symptomatology-Self Report (QIDS-SR-16) 
The QIDS-SR-16 is a 16-item patient-rated scale of symptom severity in depression. It assesses 
nine key symptoms of depression: insomnia/hypersomnia, low mood, appetite/weight changes, 
impaired self-perception, concentration difficulties, loss of interest/pleasure, suicidal ideation, 
psychomotor agitation and fatigue. Respondents use a 4-point Likert-type scale (0-3) to assess 
their behaviors and mood over the course of the past week. The total score ranges from 0-27, with 
higher scores indicating more severe depression.  
8.2 
Efficacy Assessments 
8.2.1 Montgomery-Åsberg Depression Rating Scale (MADRS) 
The MADRS is a 10-item scale designed to measure the overall severity of depressive symptoms 
(Montgomery and Åsberg, 1979). Individual items are rated by the Investigator or Sponsor-
approved rater on a scale of 0 to 6 in which a score of 6 represents the most severe symptoms for 
each item assessed. Patients are rated on items assessing feelings of sadness, lassitude, pessimism, 
inner tension, suicidality, reduced sleep or appetite, difficulty in concentration, and lack of interest. 
The MADRS total score ranges from 0 to 60. The MADRS total score at screening is a major 
inclusion criterion of the study, as well as the primary outcome measure for the study. The MADRS 
will be completed by a Sponsor-approved rater. 
8.2.2 
Clinical Global Impression-Severity (CGI-S) 
The Clinical Global Impression Scale-Severity provides the clinician’s assessment of the overall 
severity of the patient’s psychopathology (Guy, 1976). The CGI-S asks the clinician: “Considering 
your total clinical experience with this particular population, how mentally ill is the patient at this 
time?” which is rated on the following seven-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 patients. The CGI-S will be completed by a Sponsor-approved rater. 
8.2.3 
Generalized Anxiety Disorder-7 item (GAD-7) 
The GAD-7 is a 7-item self-reported questionnaire for measuring severity of symptoms of anxiety 
associated with Generalized Anxiety Disorder (Spitzer, et al 2006). Items assess 1) nervousness; 
2) inability to stop worrying; 3) excessive worry; 4) restlessness; 5) difficulty in relaxing; 
6) irritation; and 7) fear of something awful happening. Assessment is based on the total score. 
Each item is rated on a scale of Not at all (0 points); Several days (1 point); More than half the 
days (2 points); and Nearly every day (3 points). 
8.3 
Safety  
All patients who receive study treatment will be evaluated for safety. Safety assessments will 
include incidence of AEs, C-SSRS assessment for suicidality, EPS assessment as measured by 
AIMS, BARS, and SAS scales, clinical laboratory evaluations, ECG evaluations, vital sign 
measurements, and physical examination. Additional details pertaining to safety assessments are 
provided in the Schedule of Evaluations (Table 1-1).

8.3.1 
Adverse Events 
8.3.1.1 
Definition of Adverse Event 
An AE is any untoward medical occurrence associated with the use of a drug in humans, whether 
or not considered drug related. An AE can therefore be any unfavorable and unintended sign 
(including an abnormal laboratory finding, for example), symptom, or disease temporally 
associated with the use of a medicinal product, whether or not considered related to the medicinal 
product (ICH-E2A; 21 CFR 312.32[a]). 
NOTE: Medical procedures scheduled prior to obtaining informed consent but occurring during 
the study and for a pre-existing condition which did not worsen should not be captured as AEs but 
the medical reason for the procedure should be listed in the medical history if related to a pre-
existing condition. 
8.3.1.2 
Definition of Serious Adverse Event 
An SAE is any untoward medical occurrence that at any dose: 
• Results in death 
• Is life threatening 
NOTE: An AE is considered "life-threatening" if, in the view of either the Investigator or Sponsor, 
its occurrence places the patient at immediate risk of death. It does not include an AE that, had it 
occurred in a more severe form, might have caused death. 
• Requires inpatient hospitalization or prolongation of existing hospitalization 
• Results in persistent or significant disability/incapacity, or 
• Is a congenital anomaly/birth defect 
Important medical events that may not result in death, be life threatening, or require hospitalization 
may be considered serious when, based on appropriate medical judgment, they may jeopardize the 
patient and may require medical or surgical intervention to prevent one of the outcomes listed in 
this definition. 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 
patient hospitalization, or the development of study treatment dependency or drug abuse. 
Emergency room visits that do not result in hospitalization should be evaluated for one of the other 
serious outcomes to determine whether they qualify as SAEs.

Page 44 
8.3.1.3 
Classification of Adverse Events and Serious Adverse Events 
8.3.1.3.1 Severity 
The Investigator will provide an assessment of the severity of each AE by recording a severity 
rating on the appropriate AE reporting page of the patient’s eCRF. Severity, which is a description 
of the intensity of manifestation of the AE, is distinct from seriousness, which implies a patient 
outcome or AE-required treatment measure associated with a threat to life or functionality 
(Section 8.3.1.2). 
Severity will be assessed according to the following scale: 
Mild: 
A type of AE that is usually transient and may require only minimal treatment or 
therapeutic intervention. The event does not generally interfere with usual activities 
of daily living. 
Moderate: 
A type of AE that is usually alleviated with additional specific therapeutic 
intervention. The event interferes with usual activities of daily living, causing 
discomfort but poses no significant or permanent risk of harm to the research 
patient. 
Severe: 
A type of AE that interrupts usual activities of daily living, or significantly affects 
clinical status, or may require intensive therapeutic intervention. 
8.3.1.3.2 Causality Assessment 
For each reported AE and SAE, the Investigator must provide an assessment of causal relationship 
to study treatment. Causal relationship must be assessed by answering the following question: 
Is there a reasonable possibility the study treatment caused the event? 
Yes: 
There is evidence to suggest a causal relationship between the study treatment and 
adverse event, ie: 
• There is a reasonable temporal relationship between the study treatment and the event, 
and/or  
• The event is unlikely to be attributed to underlying/concurrent disease, other 
investigational products, or other factors, and/or 
• Positive dechallenge and/or rechallenge exist 
OR 
No: 
There is no evidence to suggest a causal relationship between the study treatment and 
adverse event, ie: 
• There is no reasonable temporal relationship between the study treatment and the event, or 
• The patient did not take the study treatment, or

Page 45 
• The event is likely to be attributed to underlying/concurrent disease, other investigational 
products, or other factors. 
There may be situations in which an SAE has occurred, and the Investigator has minimal 
information to include in the initial report to the Sponsor. However, it is important that the 
Investigator always makes an assessment of causality for every event before the initial 
transmission of the SAE data to the Sponsor. The Investigator may change his/her opinion of 
causality in light of follow-up information and send an SAE follow-up report with the updated 
causality assessment. 
For each AE/SAE, the Investigator must document in the medical notes that he/she has reviewed 
the AE/SAE and has provided an assessment of causality. The causality assessment must be 
recorded on the appropriate AE reporting page of the patient’s eCRF. 
8.3.1.4 
Time Period and Frequency of AE and SAE Reporting  
The Investigator will report all AEs from the time informed consent was obtained until the final 
protocol-defined study visit or last known dose date of study drug + 1 day, whichever is later.  
The Investigator will report all SAEs from the time informed consent was obtained until 30 days 
after the last known dose date of study drug. 
At each visit, patients are to be queried regarding any AEs that have occurred since the previous 
visit. Patients will be asked to volunteer information with a nonleading question such as, “How do 
you feel since your last visit?”  
8.3.1.5 
Adverse Event Reporting Procedures 
8.3.1.5.1 Reporting Adverse Events 
All AEs, including overdose with sequelae or intentional overdose of study treatment or other 
medication, must be recorded on the appropriate AE reporting page of the patient’s eCRF whether 
or not they are considered causally related to study treatment.  
For every AE, the Investigator must: 
• Provide an assessment of the seriousness of the event (ie, is it an SAE?), as well as the 
severity and casual relationship. See Section 8.3.1.2 for the definition of SAEs and Section 
8.3.1.5.2 for SAE reporting procedures. 
• Document all actions taken with regard to study treatment; 
• Detail any other treatment measures taken for the AE. 
Any AEs that are ongoing at the time of the final protocol-defined study visit will be followed 
until the condition returns to pre-study status, has resolved or stabilized, or can be explained as 
being unrelated to study treatment. If a follow-up visit is deemed necessary for appropriate safety 
surveillance, it will take place within 30 days of the final protocol-defined study visit.

8.3.1.5.2 Reporting Serious Adverse Events 
The Sponsor is required to inform worldwide regulatory authorities of SAEs that meet specific 
criteria. Therefore, the Sponsor must be notified immediately regarding any SAE that occurs after 
informed consent is obtained. Within 24 hours of learning of any AE that meets one of the criteria 
for an SAE, study center personnel must report the event to ProPharma Group on the SAE Form. 
In addition to completing the SAE form, the Study Physician may also be notified by telephone. 
If, during follow-up, any nonserious AE worsens and eventually meets any SAE criterion, that AE 
should be recorded as a new SAE. 
Preplanned hospitalizations (eg, elective procedures for pre-existing conditions that did not 
worsen, such as cosmetic surgery and hysterectomy) are excluded from SAE reporting. 
The study center must email or fax the SAE form to the SAE email address below. Even if an 
initial report is made by telephone, the SAE form containing all available details must still be 
emailed or faxed within 24 hours of knowledge of the event at the study center. 
Supplemental information should be submitted as soon as available and may include laboratory 
results, radiology reports, progress notes, hospital admission and emergency room notes, holding 
and observation notes, discharge summaries, autopsy reports, and death certificates. 
The Investigator is expected to take all therapeutic measures necessary for resolution of the SAE. 
Any medications or procedures necessary for treatment of the SAE must be recorded on the 
appropriate pages of the patient’s eCRF. All SAEs will be followed until resolution or stabilization. 
The Sponsor may contact the study center to solicit additional information or follow up on the 
event. A response is required within 24 hours of the request.

8.3.2 
Potential Hy’s Law Cases 
Study center personnel must report every patient who meets potential Hy’s Law criteria from the 
time the ICF is signed until 30 days after the final protocol-defined study visit or the last known 
dose of study treatment (if the final visit does not occur). 
The criteria for potential Hy’s law cases are as follows: 
• ALT or AST ≥ 3 × ULN and  
• Total bilirubin ≥ 2 × ULN and  
• Alkaline phosphatase < 2 × ULN 
Study center personnel must report every subject who meets these potential criteria. Typically, 
these analytes will be obtained from the same sample, but they may come from multiple samples

taken within a 24-hour period. This requirement applies from the time the ICF is signed for the 
study until 30 days after the last known dose of study treatment. 
A laboratory alert for potential Hy’s Laws cases will be in place, and the laboratory must notify 
Investigators and the Sponsor immediately when the above criteria have been met. The Sponsor 
must be notified of any potential Hy’s Law case as soon as possible (within 24 hours of learning 
of a potential Hy’s Law case). Refer to the SAE reporting procedures (Section 8.3.1.5.2) even if 
no AE has occurred. 
Every effort to determine the cause of the liver enzyme abnormalities must be made, and close 
monitoring should be initiated in conjunction with the Study Physician and in accordance with the 
FDA Guidance for Industry: Drug Induced Liver Injury—Pre-Marketing Clinical Evaluation, 
July 2009. 
8.3.3 
Pregnancy 
Female patients will not be eligible for inclusion in the study if they have a positive pregnancy test 
at the Screening or Baseline Visit. Any patient who becomes pregnant must be discontinued from 
the study. 
Study center personnel must report every pregnancy, including pregnancies in female partners of 
male study patients, from the time consent was obtained until the final protocol-defined study visit 
or last known dose of study treatment (if a final visit does not occur). 
Within 24 hours of learning of the pregnancy, study center personnel must report the event to the 
Sponsor on the Pregnancy Notification Form and email or fax it to the email address or fax number 
below even if no AE has occurred.  
• While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication 
or elective termination of a pregnancy for medical reasons will be reported as an AE or 
SAE. If the pregnancy is associated with an SAE (eg, spontaneous miscarriage or if the 
mother is hospitalized for hemorrhage), a separate SAE form must be filed as described in 
Section 8.2.1.5.2 with the appropriate serious criterion (eg, hospitalization) indicated in 
addition to the Pregnancy Notification/Outcome Form. 
• Abnormal pregnancy outcomes (eg, spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) are considered SAEs and will be reported as such. 
Any pregnancy in a study patient or in a female partner of a male study patient/subject must be 
followed to term/termination. The outcome, including status of the mother and the child, must be 
reported to the Sponsor by completing a follow-up Pregnancy Outcome Form.

Clinical Laboratory Determinations 
Blood and urine samples for clinical laboratory tests will be collected as specified in the Schedule 
of Evaluations (Table 1-1). Patients are required to fast for at least 10 hours before the collection 
of clinical laboratory blood tests at designated visits.  
During Screening, the Investigator/sub-Investigator should assess the clinical significance of any 
values that are outside the reference ranges provided by the central laboratory. Patients with 
abnormal screening laboratory results judged to be clinically significant will be excluded from the 
study. 
Laboratory results should be reviewed by the Investigator/sub-investigator throughout the study. 
For safety reasons or at the discretion of the Investigator, repeat laboratory assessments may be 
performed at an unscheduled visit. 
The following clinical laboratory levels will be measured: 
• Hematology: hematocrit; hemoglobin; red blood cell count with indices (mean corpuscular 
volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration); 
reticulocytes; white blood cell count and differential (neutrophils, lymphocytes, 
monocytes, eosinophils, and basophils) reported as percent (%) and absolute values; and 
platelet count.  
• Chemistry: albumin; alkaline phosphatase; ALT; AST; bilirubin (total, direct); blood urea 
nitrogen; calcium; chloride; cholesterol (high-density lipoprotein [HDL] and low-density 
lipoprotein [LDL] will be calculated and reported); creatinine; creatine phosphokinase; 
gamma-glutamyl transferase; glucose; insulin; lactate dehydrogenase; phosphate; 
potassium; prolactin; sodium; triglycerides; total protein; uric acid. HbA1c and TSH (reflex 
free T3 and free T4) will be measured at Screening/Visit 1 and Visit 8/ET only. 
 
• Urinalysis: macroscopic (pH, specific gravity, glucose, protein, ketones, bilirubin, nitrates, 
blood) and microscopic (red blood cells/high-power field, white blood cells/high-power 
field, casts, epithelial cells, crystals, granulation). 
• Urine Drug Screen (UDS): Urine drug tests for amphetamines, barbiturates, 
benzodiazepines, cannabinoids, cocaine metabolites, methadone, opiates, or phencyclidine 
will be performed. Any patient who tests positive for any drug at Screening, will be 
excluded from participating in the study. Exceptions may include  prescription treatments 
(eg, opioids, benzodiazepines) if the use is not chronic and is able to be discontinued as per 
the Investigator with the concurrence of the Sponsor or designee. A repeat drug test is 
allowed with the approval of the Sponsor or designee. A negative UDS is required for 
randomization. 
Additional information regarding sample collection, processing, and shipping is provided 
in the Laboratory Manual.

• Urine and serum pregnancy tests: Female patients who are of childbearing potential will 
undergo a serum pregnancy test at Screening (Visit 1) and a urine pregnancy test at 
Baseline (Visit 2) at the study clinic, and, at the discretion of the Investigator, at an 
Unscheduled Visit. Serum and urine pregnancy test will be administered at Visit 8 for 
patients who are rolling over into the Open-label Safety Study. At Visit 5 and Visit 8/ET, 
urine pregnancy tests will be administered. Serum pregnancy testing will be performed 
using blood collected as part of protocol-specified sample; urine pregnancy testing will use 
a urine dipstick. If the serum pregnancy test at screening is positive, the patient will not be 
eligible to participate in the study. If a urine pregnancy test is negative and the associated 
serum pregnancy test is positive, the patient will be discontinued from the study.  
• Hepatitis screening: Blood samples will be collected at Screening (Visit 1) from all 
patients in order to perform hepatitis B surface antigen, hepatitis B core antibody IgM, and 
hepatitis C antibody (immunoglobulin G) testing. Confirmatory testing will be undertaken 
as needed. Test results will be sent to the study site and must be reviewed before Baseline 
(Visit 2/Day 1). Any patient who tests positive for hepatitis B surface antigen and/or 
hepatitis B core antibody IgM or positive hepatitis C antibody with a positive confirmatory 
hepatitis C RNA result will be excluded from participating in the study. Details regarding 
sample collection, processing, and shipping are provided in the Laboratory Manual. 
A central laboratory will be used to evaluate all urine and blood samples, which will be collected, 
processed, and stored according to the instructions provided in the Laboratory Manual. 
8.3.5 
Vital Signs 
Vital signs (pulse rate, systolic and diastolic blood pressure [BP], body temperature, and body 
weight will be assessed at every visit during the study as specified in the Schedule of Evaluations 
(Table 1-1). Height and BMI is assessed at Screen (Visit 1) only and waist circumference will be 
assessed at Screen (Visit 1) and Visit 8/ET.  
Blood pressure and pulse rate will be measured twice: once after the patient is resting quietly in 
the supine position followed by once after at least 2 minutes in the standing positions. BP may be 
measured either manually or by machine but using the same method consistently for each patient 
throughout the study. 
Patients should be kept as calm and undisturbed as possible while BP and pulse rate measurements 
are taken (eg, there should be no talking while the BP is being measured). The same arm and BP 
cuff (appropriate to the arm circumference) should be used for all BP measurements. 
Whenever possible, the patient’s weight should be measured at the same time of day; the patient 
should wear his/her usual indoor clothing without jacket and shoes. For each patient, body weight 
and height should be determined using the same equipment during the study after ensuring its 
proper calibration.

8.3.6 
Electrocardiograms 
A 12-lead ECG will be performed as specified in the Schedule of Evaluations (Table 1-1). Each 
ECG assessment will be conducted after the patient has been resting quietly in the supine position 
and will comprise ten-second epochs from 12-lead ECGs. ECG parameters to be measured include 
HR, QRS, PR, QT, QTcB, QTcF and RR intervals. 
The overall interpretation and determination of the clinical significance of ECG findings using the 
interpretation from the central ECG laboratory will be the responsibility of the Investigator. For 
eligibility criteria, the values reported on the central ECG interpretation report, not the values that 
are printed on the tracing itself, will be used. 
8.3.7 
Columbia–Suicide Severity Rating Scale (C-SSRS) 
The C-SSRS is a clinician-rated instrument that reports the severity of both suicidal ideation and 
behavior (Posner, 2011). The C-SSRS will be completed by a Sponsor-approved rater. 
 Suicidal ideation is classified on a 5-item scale: 
1. Wish to be dead 
2. Nonspecific active suicidal thoughts 
3. Active suicidal ideation with any methods [not plan] without intent to act 
4. Active suicidal ideation with some intent to act, without specific plan; and 
5. Active suicidal ideation with specific plan and intent. 
The C-SSRS also captures information about the intensity of ideation, specifically the frequency, 
duration, controllability, deterrents, and reasons for the most severe types of ideation.  
Suicidal behavior categories are: 
• Completed suicide 
• Actual attempt 
• Interrupted attempt 
• Aborted attempt, and 
• Preparatory acts or behavior 
More than 1 classification can be selected provided it represents separate episodes. For actual 
attempts only, the actual or potential lethality is classified for the initial, most lethal, and most 
recent attempts. 
The C-SSRS will be completed at all study visits. At Screening (Visit 1), the C-SSRS will be 
completed for the patient’s lifetime history of suicidal ideation and behavior (“Baseline/Screening” 
version). At all other visits, the C-SSRS will be completed for suicidal ideation and behavior since 
the previous visit (“Since Last Visit” version). Before the patient leaves the study site, the 
Investigator or appropriately qualified designee will assess the patient’s C-SSRS results.

The patient should not be released from the study center until the results of the C-SSRS are 
reviewed and the patient is not considered to be at risk. If there is doubt about whether a patient is 
at risk, the Investigator must obtain appropriate psychiatric consultation. The results of the C-SSRS 
will be recorded in the eCRF. The C-SSRS will be completed by a trained and Sponsor-approved 
rater. 
8.3.8 
Extrapyramidal Scales 
8.3.8.1 
Abnormal Involuntary Movement Scale (AIMS) 
The AIMS (Guy 1976) measures facial and oral movements, extremity movements, and trunk 
movements. Seven items are rated on a scale from none (0) to severe (4). A score of “mild” in 2 
or more categories or a score of “moderate” or “severe” in any 1 category results in a positive 
AIMS score (ie, the scores are not averaged). Additionally, overall severity is scored on the basis 
of severity of abnormal movements and incapacitation due to abnormal movements. The patient’s 
awareness of and distress caused by the abnormal movements are also noted. There are an 
additional 2 items on dental status that are answered yes or no. The AIMS is to be completed at 
Baseline (Visit 2) and Visits 4, 6 and 8/ET according to Schedule of Evaluations (Table 1-1). 
8.3.8.2 
Barnes Akathisia Rating Scale (BARS) 
The BARS is a rating scale for drug-induced akathisia developed by Barnes (Barnes 1989). It 
includes the rating of observable restless movements, the subjective awareness of restlessness, and 
the distress associated with the akathisia. There is also a global rating for severity. The scale is 
completed by the investigator or an expert site-based rater after a standard examination. Objective 
akathisia, subjective awareness and subjective distress are rated on a 4-point scale from 0 to 3, 
yielding a total score from 0 to 9. The Global Clinical Assessment of Akathisia is rated separately, 
on a 6-point scale from 0 to 5. The BARS is to be completed at Baseline (Visit 2) and Visits 4, 6 
and 8/ET according to Schedule of Evaluations (Table 1-1). 
8.3.8.3 
Simpson-Angus Scale (SAS) 
The SAS is a measure of extrapyramidal side effects (Simpson &Angus, 1970). The SAS is used 
for assessment of antipsychotic-induced parkinsonism in both clinical practice and research 
settings. Ten items including rating gait, arm dropping, shoulder shaking, elbow rigidity, wrist 
rigidity, leg pendulousness, head dropping, glabella tap, tremor, and salivation are rated on a scale 
from 0 (normal) to 4 (extreme in severity). The SAS should be conducted by the investigator or an 
expert site-based rater in a room where the patient can walk a sufficient distance to allow a natural 
pace (eg, 15 paces). Each side of the body should be examined. The SAS is to be completed at 
Baseline (Visit 2) and Visits 4, 6 and 8/ET according to Schedule of Evaluations (Table 1-1). 
8.3.9 
Modified Physical Examination  
A modified physical examination, excluding genital/rectal examinations, will be performed at the 
visits specified in the Schedule of Evaluations (Table 1-1). The examinations will be performed 
by a professionally trained physician or health professional licensed to perform physical 
examinations.

Statistical Analyses 
9.4.1 
Patient Disposition 
The number of patients in each study population will be summarized by treatment group and study 
center as follows: 
• The number of patients who were screened will be summarized overall by study center.  
• The number of patients in the Safety and mITT populations will be summarized overall 
and by treatment group and study center.  
In addition, the number and percentage of patients who completed the Double-blind Treatment 
Period and who prematurely discontinue from the Double-blind Treatment Period will be 
summarized overall, by treatment group, and by reasons for premature discontinuation for the 
Double-blind Treatment Period. The reasons for premature discontinuation from the Double-blind 
Treatment period as recorded on the termination page of the eCRF will be summarized (number 
and percentage) by treatment group for the Safety Population. 
9.4.2 
Demographics and Other Baseline Characteristics 
Demographic parameters as allowed by local country legislation (eg, age, sex, race, ethnicity, 
weight, body mass index) and other baseline characteristics will be summarized by treatment group 
for the Safety and mITT populations. 
Prior medical and surgical history will be summarized by treatment group for the Safety 
Population. 
Baseline efficacy parameters will be summarized by treatment group for the mITT Population. 
9.4.3 
Prior and Concomitant Medication 
Prior medication is defined as any medication started and stopped before the date of the first dose 
of double-blind study treatment. A prior concomitant medication is any medication that started 
before the date of the first dose of double-blind study treatment and stopped or is ongoing after the 
date of the first dose of study treatment. Concomitant medication is defined as any medication 
taken on or after the date of the first dose of double-blind study treatment. Both prior and 
concomitant medication, including prior concomitant medication use, will be summarized as the 
number and proportion of patients in each treatment group who received each medication within 
each therapeutic class for the Safety Population. Multiple medications used by a patient will only 
be counted once. 
Any concomitant medication started after the date of the last dose of double-blind study treatment 
will not be included in the summary but will be included in the patient data listings.

9.4.4 
Extent of Exposure and Treatment Compliance 
9.4.4.1 
Extent of Exposure 
Exposure to study treatment for the Safety Population will be summarized for treatment duration, 
calculated as the number of days from the date of the first dose of double-blind study treatment 
taken to the date of the last dose taken, inclusive. The number and percentage of patients with each 
treatment duration of ≥ 1 day, ≥ 7 days, etc, will be summarized by treatment group, respectively. 
9.4.4.2 
Measurement of Treatment Compliance 
Dosing compliance for a specified period is defined as the total number of capsules of study 
treatment actually taken by a patient during the treatment period divided by the number of capsules 
of study treatment that were expected to be taken during the treatment period multiplied by 100. 
The total number of capsules actually taken during the treatment period will be calculated from 
the study treatment record. Descriptive statistics for study treatment dosing compliance together 
with compliance category will be summarized by treatment group for the Safety Population. 
9.4.5 
Efficacy Analyses 
The primary efficacy analyses and the sensitivity analysis will be based on the mITT and ITT 
Populations; other efficacy analyses will be based on the ITT Population, unless stated otherwise. 
The baseline for each specific efficacy endpoint is defined as the last measurement prior to the 
first dose of randomized treatment. All statistical hypothesis tests will be performed at the 2-sided 
5% significance level for main effects. All confidence intervals (CIs) will be 2-sided 95% CIs, 
unless stated otherwise. 
All investigative sites with fewer than 2 mITT patients per treatment group will be pooled as 
follows: The largest site with fewer than 2 mITT patients per treatment group will be pooled with 
the smallest site with fewer than 2 mITT patients per treatment group within the same country or 
geographic region. If this results in a pooled site still having fewer than 2 mITT patients per 
treatment group, this site will be pooled together with the next smallest investigative site within 
the same country or geographic region, if one exists; otherwise, no further pooling is needed. Sites 
with the same number of mITT patients will be ordered in ascending order of their numerical site 
identification number. This will serve as a tie‐breaker rule in case multiple sites have the same 
number of mITT patients. Should the primary efficacy analysis model present convergence issues, 
after testing the sequence of correlation structures, then the site effect will be reconsidered and 
may be dropped from the model. These pooled investigative sites, as determined based on the 
primary efficacy response variable, will be used for any analysis that has investigative site as a 
fixed effect in the model. The actual investigative site numbers will be included in the listings. For 
analyses that are based on the ITT Population and include site as a factor, additional pooling will 
be performed starting from the mITT pooled sites. Sites with patients who are in ITT Population 
but not the mITT Population will be pooled, using the same algorithm as outlined above.

10.2.4 
Case Report Forms 
All patient data relating to the study, except for data electronically transmitted (eg, central 
laboratory results), will be recorded on eCRFs to be provided by the Sponsor through the EDC 
system. The Investigator is responsible for verifying that all data entries in the eCRFs are accurate 
and correct by electronically signing the completed eCRFs submitted to the Sponsor. The 
Investigator must maintain and retain accurate documentation that supports the information 
entered into the EDC system for source document verification and possible regulatory inspection. 
10.2.5 
Retention and Review of Records 
Records and documents pertaining to the conduct of this study, including eCRFs, source 
documents (eg, medical records, laboratory reports), consent forms, regulatory documents, and 
medication inventory records must be retained by the Investigator for a period of at least 15 years 
after study completion unless local regulations or institutional policies require a longer retention 
period or otherwise notified in writing by the Sponsor. 
No study records shall be destroyed without notifying the Sponsor and providing the Sponsor the 
opportunity to arrange long-term storage for such study records or authorizing in writing the 
destruction of records after the required retention period. 
The Investigator must permit access to any documentation relating to the study upon request of 
the Sponsor or applicable regulatory authorities. If the Investigator for the study retires, relocates, 
or for other reasons withdraws from the responsibility of keeping the study records, custody must 
be transferred to a suitable alternate custodian employee of the institution or to a suitably qualified 
and responsible third party. The Sponsor must be notified in writing of the name and address of 
the new custodian in advance of the transfer. 
10.2.6 
Patient Confidentiality 
All patient records will be identified by patient identification number only. Patients’ names are not 
to be transmitted to the Sponsor. The Investigator will keep a master patient list on which the 
patient’s identification number and the full name, address, and telephone number are listed. 
However, the list will never leave the site and will be archived at the site after the end of the study.

Data Quality Assurance 
10.3.1 
Data Monitoring 
Before any patient enters the study, a representative of the Sponsor will meet with the Investigator 
and the study center personnel to review the procedures to be followed during the study. Electronic 
data capture (EDC) functionality training is provided via computer-based training to train 
Investigators and authorized designees on recording the data in the eCRFs using the EDC system.  
The Investigator will maintain complete source documents (eg, signed ICFs, written or electronic 
medical records, pharmacy records). Source documents provide evidence for the existence of study 
patients and substantiate the integrity of the data collected in the eCRF. The Investigator will make 
available to the Sponsor or study monitor or designee source documents (written notes and 
electronic medical records, if used), signed ICFs, and all other study-related documents. 
Study monitors or designee, appointed by the Sponsor, will perform ongoing source document 
verification to confirm that data entered into the eCRF are accurate, complete, and verifiable from 
source documents; that the safety and rights of patients are protected; and that the study is 
conducted in accordance with the currently approved protocol and any other study agreements, 
ICH GCP, and all applicable regulatory requirements. After the first patient is randomized, the 
study monitor or designee will periodically monitor the progress of the study by conducting on-
site visits. In addition to on-site source document verification, study monitors will review study 
progress remotely, possibly warranting more frequent communication and/or study center visits. 
Details of monitoring activities are provided in the Monitoring Plan. 
10.3.2 
Data Recording and Documentation 
Data collection will involve the use of the EDC system, to which only authorized personnel will 
have access. Patient data are to be entered into the EDC system by the Investigator or his/her 
designee using his/her assigned EDC user account. The Investigator or his/her designee will record 
all patients’ study data in the eCRF, unless the data are transmitted to the Sponsor electronically 
(eg, laboratory data). Data entered in the eCRF must be consistent with the source documents or 
the discrepancies must be explained. The Investigator is responsible for verifying that all data 
entries are accurate and correct. The Investigator may need to request previous or external medical 
records to support study data. 
The Sponsor is responsible for the data management of this study, including quality checking of 
the data. The Sponsor or designee will review study data for completeness, logic, and protocol 
adherence, using a combination of manual review and programmatic edit checks. After data entry 
into the EDC system by the Investigator or designee, a combination of manual and programmatic 
edit checks will be used to review the data for completeness, logic, and adherence to study 
protocol. As a result of these edit checks, data monitoring, and reviews, queries may be 
electronically issued to the study center and should be answered electronically via the EDC system. 
Each query will carry identifying information (assigned username, date, and time) to assist the 
Sponsor and the Investigator on the origin of the data clarification request and the response 
provided by the Investigator. All data changes made to the patient’s data via a data query will be 
approved by the Investigator prior to final database lock.

The Investigator or designee will be responsible for approving all changes performed on the data 
and endorsing the patient data within the EDC system. This approval method will include applying 
an electronic signature linked to a uniquely assigned username and password that together will 
represent a traditional handwritten signature used in the past. After all data have been reviewed 
and all issues have been resolved, the database will be locked. 
All data collected in the context of this study will be stored and evaluated per regulatory 
requirements and applicable guidance for electronic records. Also, data will be stored and 
evaluated in such a way as to guarantee patient confidentiality in accordance with the legal 
stipulations applying to confidentiality of data. Study records (eg, copies of eCRFs, laboratory 
reports, and regulatory documents) will be retained at the study center, along with adequate source 
documentation, according to FDA and ICH requirements. All study records must be available for 
inspection by the Sponsor, its authorized representatives, the FDA, or other health authorities.

APPENDIX I. 
ELEMENTS OF INFORMED CONSENT 
Procedures will comply with 21 CFR, Parts 50 and 312. Signed informed consent will be obtained 
for each patient participating in a clinical research study. This consent must include the following 
items: 
• A statement that the study involves research and an explanation of the purposes of the 
research; a description of the procedures to be followed and the identification of any 
procedures that are experimental; and the expected duration of the patient’s participation 
• A description of any reasonably foreseeable risks or discomforts to the patient 
• A description of any benefits to the patient or to others that may reasonably be expected 
from the research. If the patient is to be paid for participating in the study, the consent form 
must state the amount that he/she will receive and the schedule of payment (to ensure 
neither coercion nor undue influence). 
• A disclosure of appropriate alternative procedures or courses of treatment, if any, that 
might be advantageous to the patient. 
• A statement describing the extent, if any, to which confidentiality of records identifying 
the patient will be maintained and noting the possibility that the FDA or other local health 
authority, the Sponsor, the IRB/IEC, or an authorized contract research organization may 
inspect the records 
• For research involving more than minimal risk, an explanation of whether any medical 
treatment is available if injury occurs and, if so, what it consists of or where further 
information may be obtained 
• An explanation of whom to contact, including the relevant telephone number, for answers 
to pertinent questions about the research and the research patient’s rights and whom to 
contact in the event of a research-related injury to the patient. (Note: In some cases, it may 
be necessary to identify a person other than the Investigator as the contact. The guidance 
of the IRB/IEC may be required.) 
• For EU countries, the ICF will include a statement of whom to contact, including relevant 
phone and email address, for questions about patient data confidentiality or data breach’ 
per GDPR. 
• A statement that participation is voluntary, that refusal to participate will involve no 
penalty or loss of benefits to which the subject/patient is otherwise entitled, and that the 
patient may discontinue participation at any time without penalty or loss of benefits to 
which the patient is otherwise entitled 
• A statement that the treatment or procedures may involve risks to the patient (or to the 
embryo or fetus if the patient is, or may become, pregnant) that are at present unforeseeable 
• The expected circumstances for which the patient’s participation may be terminated by the 
Investigator without regard to the patient’s consent
