SYNOPSIS AND SCHEDULE OF EVALUATIONS
CLINICAL STUDY SYNOPSIS: Study RAP-MD-33
Study Number
RAP-MD-33 (3106-333-008)
Title of Study
A Randomized, Double-blind, Placebo-controlled, 
Multicenter Study of Rapastinel in the Prevention of Relapse 
in Patients with Major Depressive Disorder
Study Centers (Country)
Approximately 145 study centers
Development Phase
3
Objective
To evaluate the efficacy, safety, and tolerability of rapastinel 
relative to placebo in the prevention of relapse in patients 
with major depressive disorder (MDD)
Methodology
Multicenter, randomized-withdrawal, parallel-group, 
placebo-controlled, maintenance study in patients with 
MDD.
For patients enrolling from RAP-MD-30, RAP-MD-31, or 
RAP-MD-32 (lead-in studies), the final visit from that study 
(ie, Visit 9) will serve as Visit 1 in Study RAP-MD-33.
This study comprises the following periods:

An 8- to 16-week, open-label treatment period (OLTP) 
during which patients will receive intravenous (IV) 
rapastinel (450 mg or 225 mg) once weekly to identify 
stable responders. Individual treatment duration in the 
period will be at least 8 weeks and up to 16 weeks to 
accommodate variability among patients and adequately 
identify stable responders (patients treated for a 
minimum of 8 weeks and meet OLTP stability 
assessment criteria)

A 52-week, double-blind, randomized-withdrawal period 
during which stable responders from the open-label 
period will be randomized (1:1:1) to 1 of 3 double-blind 
treatment arms: 
o
Rapastinel weekly (IV, 450 mg or 225 mg)
o
Rapastinel clinically driven schedule (IV, 450 
mg or 225 mg, variable interval, placebo on 
intervening weeks)
o
Placebo weekly (IV)

A 2-week safety follow-up period.
Number of Patients
Approximately 1400 planned to be enrolled in the OLTP; 
approximately 600 planned to be randomized during the 
double-blind treatment period (DBTP)

Diagnosis and Main Criteria for 
Inclusion

Completion of RAP-MD-30, RAP-MD-31, or RAP-MD-
32

Male or female outpatients, 18 to 75 years of age (at 
time of entry to lead-in study)
 
 
 
Test Product, Dosage, and Mode 
of Administration
OLTP: Patients will receive IV rapastinel (450 mg or 225 
mg weekly) once weekly. The dose assigned in the OLTP 
will be based on the dose received in the lead-in study such 
that those who received placebo, vortioxetine, or 450 mg or 
900 mg rapastinel in the lead-in study will be assigned 450
mg rapastinel, while those who received 225 mg rapastinel 
in the lead-in study will be assigned 225 mg rapastinel.  
DBTP: The study center investigator will submit the clinical 
assessment to the interactive web response system (IWRS) at 
each visit in a blinded manner.  Depending on the assigned 
treatment arm, the IWRS will dispense the following 
treatments:

Rapastinel weekly arm: rapastinel (450 mg or 225
mg, based on dose patient received in OLTP), 
regardless of clinical assessment

Rapastinel clinically-driven schedule arm: 
o
“Clinically unstable”: rapastinel (450 mg or 
225 mg, based on dose patient received in 
OLTP)
o
“Clinically stable”: placebo IV 

Placebo weekly arm: placebo IV at each visit, 
regardless of clinical assessment
Duration of Participation
An 8- to 16-week OLTP; a DBTP with a maximum duration 
of 52 weeks; and a 2-week Safety Follow-up Period.  Each 
randomized patient will be treated until relapse criteria are 
met or until he/she has completed 52 weeks of double-blind 
treatment or discontinued for other reasons.
Reference Therapy, Dosage, and 
Mode of Administration

Severity (CGI-S) score compared with that obtained 
at randomization, or
o
Risk of suicide as determined by the investigator, or
o
Need for hospitalization due to worsening of 
depression as determined by the investigator, or
o
Need for alternative treatment of depressive 
symptoms as determined by the investigator

Statistical Methods
The primary efficacy analysis will compare the time to 
relapse between placebo and rapastinel treatment groups in
the respective time-frame (within the 52 weeks of the DBTP) 
using the log-rank test and the Double-blind Modified 
Intent-To-Treat (mITT) Population. Estimates of the hazard 
ratio and 95% confidence intervals will be based on the Cox 
proportional hazards model with treatment group as an 
explanatory variable. The cumulative distribution function of 
time to relapse will be characterized by the Kaplan-Meier 
curves.
All safety parameters will be analyzed descriptively for the 
Open-label Safety Population and the Double-blind Safety 
Population.
The Open-label Safety Population will consist of all 
screened patients who receive at least 1 dose of 
investigational product (IP) during the OLTP.
The Double-blind Safety Population will consist of all 
randomized patients who receive at least 1 dose of double-
blind IP during the DBTP of the study.
The Double-blind mITT Population will consist of all 
patients in the Double-blind Safety Population who had at 
least 1 postrandomization assessment of MADRS or CGI-S
during the DBTP of the study.

INTRODUCTION
Disease Burden of Major Depressive Disorder
Major depressive disorder (MDD) is a highly disabling, serious condition which is 
associated with significant morbidity and mortality. MDD manifests as a major 
depressive episode (which may be singular or recurrent) in which the affected individual 
experiences 1) depressed mood, or 2) loss of interest or pleasure (as well as other 
symptoms) for most of the day, nearly every day, for at least 2 weeks. MDD affects 
approximately 14.8 million American adults, or about 6.7% of the US population 18 
years of age and older, in a given year (Kessler et al, 2005). Worldwide, about 15% of the 
adult population is at lifetime risk of developing MDD (Kessler et al, 1994).
Depression may cause serious, long-lasting symptoms and often disrupts a person’s 
ability to perform routine tasks. In 2000, unipolar depressive disorders were by far the 
leading cause (11.9%) of worldwide years of life lived with disability (World Health 
Organization, 2001), and the total economic burden of treating depression in the United 
States was $83.1 billion, with workplace costs, including missed days and lack of 
productivity due to illness, accounting for most of the total economic burden (62%). 
Other economic burdens in 2000 included $26.1 billion (31%) for treatment costs and 
$5.4 billion (7%) for suicide-related costs (Greenberg et al, 2003). 
MDD is a leading cause of disability in the United States (Murray et al, 2013). Moreover, 
MDD is known to be a significant risk factor for suicide and ischemic heart disease, as it 
accounted for 16 million of the disability adjusted life years (DALYs) associated with 
suicide and 4 million of the DALYs associated with ischemic heart disease. Research has 
shown that untreated depression has both a functional (social and work role) as well as a 
neuroanatomical (hippocampal shrinkage) effect on the patient (Videbech and Ravnkilde, 
2004). Given the disease burden and link to suicidality as well as increased mortality with 
other comorbid conditions, MDD is a serious and life-threatening condition which is a 
leading cause of disability in the world.

Selective Serotonin Reuptake Inhibitors and Selective Serotonin Norepinephrine 
Reuptake Inhibitors in Major Depressive Disorder
Selective serotonin reuptake inhibitors (SSRIs) and selective serotonin and 
norepinephrine reuptake inhibitors (SNRIs) currently represent the first line of treatment 
of depression in the United States. Unfortunately, a large number of patients do not 
experience therapeutic benefit from these first-line agents (Rosenzweig-Lipson et al, 
2007). Lack of sufficient response to adequate treatment remains a critical problem in the 
management of patients with MDD. Up to two-thirds of patients treated with first-line 
antidepressant monotherapy do not reach full remission, and as many as a third become 
treatment resistant (Fava and Davidson, 1996; Trivedi et al, 2006). Not achieving 
remission has been shown to be predictive of poorer psychosocial functioning, higher 
rates of relapse, and higher rates of rehospitalization (McIntyre and Donovan, 2004). The 
results of the STAR*D study suggest that with successive failures of treatment, patients 
are less and less likely to respond to subsequent treatment, and those who do respond are 
more likely to relapse (Rush et al, 2006). Present strategies available to treat patients who 
do not respond to first-line antidepressant monotherapy include switching of 
antidepressant (either within or between classes); combination therapy in which multiple 
antidepressants are used simultaneously; augmentation of ongoing antidepressant 
monotherapy with adjunctive use of drugs such as mood stabilizers or atypical 
antipsychotics (Boland and Keller, 2006), and nonpharmacologic treatments including 
psychotherapy and phototherapy, vagus nerve stimulation, transcranial magnetic 
stimulation, and electroconvulsive therapy. Clearly, there remains a critically important 
unmet medical need for this patient population.
Existing antidepressants have a number of limitations, leading to considerable unmet 
medical need in the effective treatment of MDD, with up to 50% of patients with MDD 
having an inadequate response or failing current antidepressant therapy (ADT). Currently 
available first-line antidepressants (SSRIs, SNRIs) typically take 3 to 4 weeks or more of 
continuous daily dosing to relieve symptoms of MDD and are associated with side effects 
related to their pharmacological mechanisms of action (sexual dysfunction, weight gain, 
jitteriness, sleep disturbances), which are further associated with poor patient compliance 
(Masand, 2003; Ashton et al, 2005). Patients often experience undesirable side effects 
before they experience an improvement in depressive symptoms, which could lead to 
premature discontinuation of therapy. Taken together, these factors define significant 
areas for improvement of ADT.

Patients vary greatly in their response to antidepressants and it is not possible to reliably 
predict whether an individual patient will respond to a given antidepressant. This leads to 
clinicians often using a trial-and-error approach to identify an effective antidepressant. 
Due to the gradual development of the full therapeutic effect of currently available 
antidepressants, each antidepressant needs to be administered for 4 weeks or longer in 
order to determine the individual therapeutic benefit, making the process of finding an 
effective antidepressant lengthy for patients who are often severely depressed and at a 
high risk for suicide. A drug that could induce a rapid antidepressant effect would 
represent a major advancement for these patients.
Clearly, there is a substantial need for the development of novel treatments with a better 
safety/tolerability profile and a faster onset of full therapeutic benefit. Rapastinel has 
initially shown substantially improved safety/tolerability as well as promising efficacy, in 
both speed of onset and overall magnitude, for therapy in MDD. 
Rapastinel as a Novel Approach to Major Depressive Disorder Treatment
The mechanism of action of rapastinel is entirely different from that of first-line 
antidepressants (SSRIs, SNRIs) or adjuvant drugs currently approved for treatment of 
MDD such as atypical antipsychotics. Rapastinel is an N-methyl-D-aspartate receptor 
(NMDAR) modulator with a novel and complex pharmacological mechanism of action, 
acting as a nonselective agent at NR2 subunits and displaying properties as a functional 
partial agonist in a number of pharmacological assays. 
Rapastinel has demonstrated antidepressant properties in relevant animal models, 
displays cognitive enhancing properties in treated animals, and facilitates hippocampal 
long-term potentiation of synaptic transmission in preclinical models. In contrast to 
ketamine, no signal of abuse liability was detected in informative animal models. 
Rapastinel is available as an intravenous (IV) formulation only. In 2 Phase 2 clinical 
studies in patients with MDD, single IV doses of rapastinel 5 mg/kg and 10 mg/kg have 
been shown to produce marked antidepressant effects within 1 day that lasted for 
approximately 1 week or longer in responding patients. These antidepressant effects are 
very similar to ketamine’s effects when administered at a low dose as an infusion. In a 
systematic review and meta-analysis of ketamine and other NMDAR antagonists in the 
treatment of major depression, a single infusion of ketamine produced a rapid, yet 
transient antidepressant effect, accompanied by brief psychotomimetic and dissociative 
effects (Newport et al, 2015). 
The available Phase 1 and 2 data demonstrated a favorable safety and tolerability profile 
of rapastinel. In contrast to ketamine, rapastinel has not shown a high likelihood to induce 
psychotomimetic or dissociative effects in humans so far.

INVESTIGATIONAL PLAN
9.1
OVERALL STUDY DESIGN AND PLAN: DESCRIPTION
Study RAP-MD-33 is a multicenter, randomized-withdrawal, parallel-group, placebo-
controlled, maintenance study of rapastinel as monotherapy in adult patients with MDD 
who completed the RAP-MD-30, RAP-MD-31, or RAP-MD-32 DBTP.  The final visit 
from the lead-in study (ie, Visit 9) will serve as Visit 1 in Study RAP-MD-33. 
This study will be conducted in the following periods:

An 8- to 16-week, Open-label Treatment Period (OLTP) 

A 52-week, DBTP, randomized-withdrawal period during which stable responders 
from the open-label period will be randomized (1:1:1) to 1 of 3 double-blind 
treatment arms: 
o
Rapastinel weekly (IV, 450 mg or 225 mg)
o
Rapastinel clinically driven schedule (IV, 450 mg or 225 mg, variable 
interval, placebo on intervening weeks)
o
Placebo weekly (IV) 

A 2-week Safety Follow-up Period
Approximately 1400 patients are planned for enrollment in the OLTP to achieve 
approximately 600 randomized patients in the DBTP. When approximately 600 patients 
are randomized into the DBTP, enrollment in the OLTP will be closed.
A schematic of the study design is presented in Figure 9.1.3–1.  The Schedule of 
Evaluations is provided in Section 2.0.
9.1.1
Open-label Treatment Period
Patients will enroll from Study RAP-MD-30, RAP-MD-31, or RAP-MD-32, and the final 
visit from that study (Visit 9/ET [Week 6]) will serve as Visit 1 in Study RAP-MD-33. 
Patients will be screened at Visit 1 and those who meet entry criteria will also enter the 
OLTP at Visit 1 and will receive the first dose of open-label treatment (rapastinel) at 
Visit 1 to ensure continuity of treatment.


Naurex, Inc.

RAP-MD-33 Protocol Final
02 May 2018
The OLTP consists of weekly visits for at least 8 weeks (and up to 16 weeks). During this 
period, patients will be treated with weekly IV injections of rapastinel (450 mg or 225 
mg). The dose assigned in the OLTP will be blinded and be based on the dose received in 
the lead-in study such that those who received placebo, vortioxetine, or 450 mg or 900
mg rapastinel in the lead-in study will be assigned 450 mg rapastinel, while those who 
received 225 mg rapastinel in the lead-in study will be assigned 225 mg rapastinel.
The purpose of this period is to identify stable responders who will be eligible for the 
randomized-withdrawal period.
Patients will be monitored through the OLTP stability assessment.  A patient will be 
considered to have met OLTP stability criteria upon achieving both:

MADRS total score ≤ 12 with no more than 1 modest MADRS excursion 
(MADRS > 12 but ≤ 16) during 6 consecutive weeks, and  

MADRS total score ≤ 12 for 2 consecutive visits prior to randomization
Patients may meet OLTP stability assessment criteria at any point from Study Week 8 to 
Study Week 16.  
Patients who do not meet stability criteria within these timeframes will undergo the End-
of-Treatment/Early Termination assessments (Visit 69/Week 52/ET) at their last OLTP 
visit.  
Patients who discontinue from Study RAP-MD-33 OLTP will enter a 2-week safety 
follow-up period.
9.1.2
Double-Blind Treatment Period
Approximately 600 patients are planned for randomization in the DBTP. 
Upon meeting stability criteria, patients will enter the DBTP. Each patient entering the 
DBTP will be randomized 1:1:1 to 1 of 3 double-blind treatment arms:

Rapastinel weekly arm: weekly IV administration of rapastinel (450 mg or 225
mg, based on dose patient received in OLTP) 

Rapastinel clinically driven schedule arm: IV administration of rapastinel (450
mg or 225 mg, based on dose patient received in OLTP) given on a response-
based variable schedule depending on the clinical assessment at the respective 
visit with placebo given at intervening visits. 

Placebo weekly arm: weekly IV administration of placebo
At each visit during the DBTP, each patient will be assessed clinically to determine 
whether a patient is considered:


Naurex, Inc.
30
RAP-MD-33 Protocol Final
02 May 2018

“Clinically stable”, defined as meeting all of the below:
o
MADRS total score ≤ 12
o
≤ 4-point increase in MADRS total score from prior visit
o
≤ 1-point increase in CGI-S score from prior visit
o
Patient does not require intervention based on the discretion of the 
investigator
or 

“Clinically unstable”, defined as not meeting one or more of the criteria above
Implementation of the rapastinel clinically driven schedule arm will be based on 
individual patient response and clinical presentation. The study center investigator will 
submit the clinical assessment to the interactive web response system (IWRS) at each 
visit. Depending on the assigned treatment arm, the IWRS will dispense the following 
treatments in a blinded manner:

Rapastinel weekly arm: rapastinel (450 mg or 225 mg, based on dose patient 
received in OLTP), regardless of clinical assessment

Rapastinel clinically-driven schedule arm: 
o
“Clinically unstable”: rapastinel (450 mg or 225 mg, based on dose patient 
received in OLTP)
o
“Clinically stable”: placebo IV

Placebo weekly arm: placebo IV at each visit, regardless of clinical assessment
Patients will be monitored for relapse events defined as meeting any of the following 
criteria:

MADRS total score ≥ 18 at 2 consecutive MADRS assessments

≥ 2 increase in CGI-S score compared with that obtained at randomization

Risk of suicide as determined by the investigator

Need for hospitalization due to worsening of depression as determined by the 
investigator

Need for alternative treatment of depressive symptoms as determined by the 
investigator 
Upon meeting any of the relapse criteria at any visit in the DBTP, the patient will be 
considered a completer and the Visit 69/ET Visit procedures should be conducted.

Each randomized patient will be treated until relapse criteria are met, or until he/she has 
completed 52 weeks of double-blind treatment or discontinued for other reasons.  The 
study will be terminated when all randomized patients have either met relapse criteria, 
early terminated for other reasons, or completed 52 weeks of the DBTP and completed 
the safety-follow up period where appropriate.
Upon completion of the DBTP, patients will enter a 2-week safety follow-up period.
9.1.3
Safety Follow-up Period
All patients who complete or discontinue from the study should enter the 2-week safety 
follow-up period.
Additional follow-up visits may be scheduled within 30 days, if necessary, for safety 
reasons.
A schematic of the study design is presented in Figure 9.1.3–1. The Schedule of 
Evaluations is provided in Section 2.0 and detailed descriptions of each study visit can be 
found in Section 9.5.5.

DISCUSSION OF STUDY DESIGN, INCLUDING THE CHOICE 
OF CONTROL GROUPS
This multicenter, randomized-withdrawal, placebo-controlled, parallel-group,
maintenance study, was designed based on prior studies that established rapastinel 
efficacy and safety in adult patients with MDD. The placebo-controlled withdrawal 
design is considered standard to demonstrate effectiveness of long-term maintenance 
treatment (Borges et al, 2014; EMA/CHMP/185423/2010 Rev 2).
Study centers will have experience with the study population and will be encouraged to 
apply available guidelines to minimize patient risk or distress. 
Dose selection information is presented in Section 9.4.5. The planned dosing regimen is 
based on experience from previous rapastinel studies. 


Naurex, Inc.
33
RAP-MD-33 Protocol Final
02 May 2018
The 8- to 16-week OLTP was designed to ensure sustained response following continued 
rapastinel treatment. The double-blind design is included to minimize systematic bias 
resulting from the scale raters, patient, or investigator knowing the treatment being 
administered. Randomization at the beginning of the DBTP is expected to minimize 
patient selection bias and increase baseline comparability of the 3 treatment groups. 
The use of placebo control is critical to the study design both to understand the safety 
findings of the drug and to ensure that efficacy results can be interpreted. In this study, 
the placebo control is used during the DBTP to demonstrate the reemergence of MDD
symptoms upon withdrawal of rapastinel compared with patients who continue rapastinel 
treatment. Patients who continue rapastinel treatment should maintain improvement in 
their MDD symptoms, whereas those who switch to placebo should have a return of 
MDD symptoms. 
The duration of the DBTP of 52 weeks was selected to provide sufficient time to 
demonstrate MDD relapse upon withdrawal of rapastinel and this duration is at the upper 
end of what is typically employed in withdrawal design maintenance studies 
(Borges et al, 2014). 
The 2-week safety follow-up period allows continued patient monitoring after the IP has 
been discontinued.
In Study RAP-MD-33, safety and efficacy assessments are included at appropriate 
intervals to determine efficacy, safety, and tolerability. In the event of insufficient 
therapeutic response or worsening of the patient’s initial condition, the IP may be 
discontinued at the investigator’s discretion and an alternative treatment will then be 
allowed (Section 9.4.12). 
An independent Data and Safety Monitoring Board (DSMB) will evaluate safety data 
during the study (Section 9.8).

SELECTION OF STUDY POPULATION
9.3.1
Inclusion Criteria
Note: Patients roll over into RAP-MD-33 after completion of the lead-in study (RAP-
MD-30, RAP-MD-31, or RAP-MD-32); therefore medical, psychiatric, and medication 
histories from Visit 1 of the lead-in study will be used to support entry into Study RAP-
MD-33.
To be eligible to participate in the study, patients must meet the following criteria:
Criteria to be assessed at Visit 1
1. Written informed consent, obtained from the patient before the initiation of any 
study-specific procedures (Section 5.3) 
2. Completion of Study RAP-MD-30, RAP-MD-31, or RAP-MD-32
3. Male or female outpatients, 18 to 75 years of age (at time of entry to lead-in study)
 
 
 
 
 
5. If female of childbearing potential, has a negative serum β-human chorionic 
gonadotropin (β-hCG) pregnancy test.  Because Visit 1 pregnancy test results will not 
be available on the day of Visit 1, patients can be discontinued at Visit 2 if Visit 1 
pregnancy test is positive.

Removal of Patients from Therapy or Assessment
A premature discontinuation will occur when a patient who signed the ICF ceases 
participation in the study, regardless of circumstances, before the completion of the study 
visits and procedures. Patients can be prematurely discontinued from the study after 
careful consideration for one of the following reasons:

Screen failure (failure to meet inclusion/exclusion criteria)

Pregnancy

Withdrawal of consent 

AE

Lack of efficacy

Protocol violation

Noncompliance with IP


Other 
All treated patients who prematurely discontinue from the study, regardless of cause, 
should be seen for a final assessment at an ET Visit. A final assessment will be defined as 
completion of the evaluations scheduled for all patients at Visit 69. All treated patients 
discontinuing the study prematurely should enter the 2-week safety follow-up period.
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 will be contacted 
by the sponsor (or designee) after each premature discontinuation to ensure proper 
characterization of the reason for discontinuation is captured.
9.3.3.1
Criteria for Required Removal of Patients from Therapy or 
Assessment
Any patient who meets any of the following criteria at any point during the study must be 
withdrawn from participation, due to AEs related to suicide:

A suicide attempt

Significant risk, as judged by the investigator, based on the psychiatric 
interview or information collected in the C-SSRS

MADRS Item 10 score ≥ 5
In the event that a patient is withdrawn for a suicide-related AE, the patient should be 
referred for additional treatment or hospitalization, as clinically indicated, in addition to 
withdrawing the patient from the study.

TREATMENTS
During the OLTP, all eligible patients will receive open-label, once-weekly IV rapastinel 
(225 mg or 450 mg). Patients who meet eligibility criteria at the end of the OLTP will be 
randomized in a double-blind fashion to 1 of 3 treatment groups: rapastinel weekly, 
rapastinel on a clinically driven schedule, or placebo weekly.
9.4.1
Treatments Administered
IP will only be administered to eligible patients by a medically qualified person as per the 
local and/or state regulations. The range of persons who can administer an IV can be a 
physician, a physician assistant, nurse, or nurse practitioner, etc, depending on the local 
and/or state law.  
IP should be administered after all efficacy and safety assessments with the exception of 
assessments specified in this protocol as requiring postdose administration.
The IP will be administered using the provided prefilled syringes in a “slow bolus” 
injection to an upper extremity vein within approximately 1 to 2 minutes to each study 
patient. 
During IP administration and until completion of postadministration assessments, a 
licensed physician must be immediately available and in close proximity to the patient(s) 
to attend to medical emergencies.  The facility must have the capabilities, in accordance 
with the country and/or local regulations/standard of care, to resuscitate a patient in the 
event of a medical emergency.  
At IP administration visits, the patient should not be released from the study center until 
the following are completed:

Postadministration pulse rate and BP measures (approximately 15 minutes after 
administration)

Patient is clinically assessed and determined to not be at increased risk of 
suicidality in the opinion of the investigator (or medically qualified 
subinvestigator)

Patient is assessed for mental status and is determined to be free of perceptual 
disturbances or other conditions that would deem them not ready for release from 
the study center, in the opinion of the investigator (or medically qualified 
subinvestigator)


A physician licensed in the country, state, or other local regulatory authority 
(investigator or subinvestigator) determines that they are medically able to leave 
the study center and provides written signoff not less than 15 minutes following 
administration (see IV Administration and Evaluation Notes document in Study

9.4.3
Handling of Investigational Products
The IP must be stored in a secure area and administered only to patients entered into the 
clinical study, at no cost to the patient, in accordance with the conditions specified in this 
protocol.
 
Study centers must report any temperature 
excursions as described in the Study Reference Manual or contact the sponsor or its 
designee for further instructions. 
At the end of the study, all IP must be accounted for. In addition, at the end of the study, 
all unused IP and empty IP packages should be returned to the sponsor or the local 
distributor at the address provided in the Study Reference Manual.
9.4.4
Method of Assigning Patients to Treatment Groups
After a patient signs the consent form at Visit 1, study personnel will register the patient 
in the IWRS.  All patients entering from the lead-in studies (RAP-MD-30, RAP-MD-31, 
or RAP-MD-32) will be identified using the same PID that was assigned by the IWRS in 
the lead-in study. 
This PID number will be used to identify the patient throughout the study (ie, at all 
periods of the study).
The IP 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 each administration. 
Study centers will dispense IP according to the IWRS instructions. Study centers will also 
log on to the IWRS at subsequent visits to obtain an IP kit number for dispensing the IP. 
Study centers will receive the IWRS confirmation notifications for each transaction. All 
notifications are to be maintained with the study source documents.
9.4.5
Selection of Dosages in the Study
The doses of rapastinel in this study were selected based on 2 Phase 2 clinical studies in 
patients with MDD, in which single IV doses of rapastinel 5 mg/kg and 10 mg/kg were
shown to produce marked antidepressant effects within 1 day that lasted approximately
1 week or longer in responding patients.
A 450-mg IV unit dose is expected to be appropriate for most patients as this represents a 
dose of 4.5 mg/kg in a 100-kg patient and a dose of 9 mg/kg in a 50-kg patient.


Naurex, Inc.
41
RAP-MD-33 Protocol Final
02 May 2018
A 225-mg IV unit dose (equivalent to 2.25 mg/kg in a 100-kg patient and a dose of 4.5
mg/kg in a 50-kg patient) is available only to patients entering from RAP-MD-30 to 
allow for further evaluation of the dose-response profile after multiple dosing.
9.4.6
Selection and Timing of Dose for Each Patient
9.4.6.1
Open-label Treatment Period
During the OLTP, patients will be treated with weekly IV injections of rapastinel (450 
mg or 225 mg). The dose assigned in the OLTP will be blinded and be based on the dose 
received in the lead-in study such that those who received placebo, vortioxetine, 450 mg 
or 900 mg rapastinel in the lead-in study will be assigned 450 mg rapastinel, while those 
who received 225 mg rapastinel in the lead-in study will be assigned 225 mg rapastinel.
9.4.6.2
Double-blind Treatment Period
During the DBTP, patients will be randomized 1:1:1 to 1 of 3 double-blind treatment 
arms:

Rapastinel weekly arm: weekly IV administration of rapastinel (450 mg or 225
mg, based on dose patient received in OLTP) 

Rapastinel clinically driven schedule arm: IV administration of rapastinel (450
mg or 225 mg, based on dose patient received in OLTP) given on a response-
based variable-schedule depending on the clinical assessment at the respective 
visit with placebo given at intervening visits. 

Placebo weekly arm: weekly IV administration of placebo
At each visit during the DBTP, each patient will be assessed clinically to determine 
whether a patient is considered:

“Clinically stable”, defined as meeting all of the below:
o
MADRS total score ≤ 12
o
≤ 4-point increase in MADRS total score from prior visit
o
≤ 1-point increase in CGI-S score from prior visit
o
Patient does not require intervention based on the discretion of the 
investigator
or 

“Clinically unstable”, defined as not meeting one or more of the criteria above
Implementation of the rapastinel clinically driven schedule arm will be based on 
individual patient response and clinical presentation. The study center investigator will
submit the clinical assessment to the IWRS at each visit. Depending on the assigned 
treatment arm, the IWRS will dispense the following treatments in a blinded manner:


Naurex, Inc.

9.4.6.3
Safety Follow-up Period 
No IP is administered during the safety follow-up period.
9.4.7
Blinding
For the OLTP, the list of patient randomization codes from the lead-in studies will be 
implemented by the IWRS vendor (an electronic version will be stored on a secure 
server). This list will identify each patient by randomization number and include the 
patient’s corresponding treatment assignment from the lead-in study to establish 
appropriate dosing of rapastinel in the OLTP.
For the DBTP, a list of patient randomization codes will be generated by Statistical 
Programming and implemented by the IWRS vendor (an electronic version will be stored 
on a secure server). This list will identify each patient by randomization number and 
include the patient’s corresponding treatment assignment in the DBTP.
All study treatments will be provided in identical syringes and cartons to maintain 
masking of the study.
9.4.8
Unblinding
Any unblinding at the study center level should be done only in an emergency that 
requires the IP to be identified for the medical management of the patient. The 
investigator must notify the Study Physician immediately (refer to Appendix II) and a full 
written explanation must be provided if the blind is broken. Before the IP is unblinded, 
every attempt should be made to discuss the case with the Study Physician. Breaking the 
code at the study center will immediately disqualify the patient from further participation 
in the study.
Treatment codes may be broken by Global Drug Safety for regulatory reporting purposes. 
In such cases, the study staff will be kept blinded and the patient will not need to be 
disqualified from the study.
In an emergency, the investigator can obtain the treatment assignment of any patient at 
his or her study center through the IWRS.

injection, implant), male condom with intravaginal spermicide, diaphragm or cervical cap 
with spermicide, vaginal contraceptive ring, intrauterine device [IUD], surgical 
sterilization (bilateral tubal ligation, bilateral salpingectomy), implantable permanent 
birth control device (ie Essure; note: device must be in place at least 3 months and 
completed confirmation test), vasectomized partner, or complete abstinence for the 
duration of the study (periodic abstinence [such as calendar, ovulation, symptothermal, 
post-ovulation methods] and withdrawal are not acceptable methods of contraception).
Note: In Germany, the Czech Republic, and other local regions as applicable, acceptable 
methods of contraception include complete abstinence; single barrier (diaphragm or 
condom) combined with the use of IUD or contraceptive (oral, implantable, or 
injectable); or double barrier (diaphragm with condom).
The investigator and each patient will determine the appropriate method of contraception 
for the patient during the participation in the study with consideration for local regulatory 
or IRB/EC requirements.
See Section 9.5.2.3 for pregnancy reporting procedures.
9.4.11
Monitoring Treatment Compliance
IP compliance during any period will be closely monitored by capturing the date and time 
of each injection of IP. If a scheduled IV injection does not occur, the sponsor must be 
notified and the reason recorded.
9.4.12
Treatment After Discontinuation
Patients whose MDD symptoms worsen or are determined by the investigator not to be 
adequately controlled prior to completing the OLTP or DBTP will be allowed to 
discontinue the study and start appropriate treatment at the investigator’s discretion. This 
new treatment will not be provided by the sponsor. Patients who initiate a new treatment 
for MDD must be discontinued from the study.

9.5.2
Safety Assessments
Patients must be evaluated by a physician or an appropriately trained health care 
professional at every visit and the evaluation must be documented. The procedures 
discussed below will be completed at the designated visits.
9.5.2.1
Adverse Events
An AE is any untoward medical occurrence in a patient or clinical investigation patient 
administered a pharmaceutical product and which does not necessarily have to have a 
causal relationship with this treatment. 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).
For the purpose of the study center’s data collection responsibilities, any untoward event 
that was reported from the time the patient signed the ICF until 30 days after the final 
protocol-defined study visit or the last known dose of IP (if the final visit does not occur)
is to be considered an AE.


Naurex, Inc.
48
RAP-MD-33 Protocol Final
02 May 2018
Examples of AEs are as follows:

Changes in the general condition of the patient

Subjective symptoms offered by or elicited from the patient

Objective signs observed by the investigator or other study center personnel

All diseases that occur after signing informed consent, including any change in 
severity or frequency of pre-existing disease

All clinically relevant abnormalities in laboratory values or clinically relevant 
physical findings that occur during the study schedule
Please note that medical procedures scheduled prior to consenting, but occurring during 
the study should not be captured as AEs, but should be listed in the medical history if 
related to a pre-existing condition.
9.5.2.1.1
Causality Assessment
For each AE, the investigator must provide an assessment of causal relationship to the IP. 
The causality assessment must be recorded on the appropriate AE reporting page of the 
patient’s eCRF. Causal relationship must be assessed by answering the following 
question:
Is there a reasonable possibility the IP caused the event?
Yes:
There is evidence to suggest a causal relationship between the IP and AE, ie: 

There is a reasonable temporal relationship between the IP and the event, 
and/or 

The event is unlikely to be attributed to underlying/concurrent disease or other 
factors, and/or

Positive dechallenge and/or rechallenge exist
No:
There is no evidence to suggest a causal relationship between the IP and AE, 
ie:

There is no reasonable temporal relationship between the IP and the event, or

The patient did not take the IP, or


Naurex, Inc.
49
RAP-MD-33 Protocol Final
02 May 2018

The event is likely to be attributed to underlying/concurrent disease or other 
factors, or

The event is commonly occurring in the (study) population independent of IP
exposure
9.5.2.1.2
Severity Assessment
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 9.5.2.1.3). 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 participant.
Severe:
A type of AE that interrupts usual activities of daily living, or significantly 
affects clinical status, or may require intensive therapeutic intervention.
9.5.2.1.3
Serious Adverse Events
An SAE is any untoward medical occurrence that at any dose:

Results in death

Is life threatening

Requires inpatient hospitalization or prolongation of existing hospitalization

Results in persistent or significant disability/incapacity, or

Is a congenital anomaly/birth defect


Naurex, Inc.
50
RAP-MD-33 Protocol Final
02 May 2018
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 IP 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.
Preplanned hospitalizations (eg, elective procedures for pre-existing conditions that did 
not worsen, such as cosmetic surgery and hysterectomy) are excluded from SAE 
reporting.
9.5.2.1.4
Reporting Adverse Events and Serious Adverse Events
At each visit, patients are to be queried regarding any AEs or SAEs 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?” Study center personnel will 
record all pertinent information in the patient’s eCRF. 
All AEs must be recorded on the appropriate AE reporting page of the patient’s eCRF 
whether or not they are considered causally related to the IP.
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

Document all actions taken with regard to the IP

Detail any other treatment measures taken for the AE

Document the outcome of the AE
In addition, patients are to be reminded, as described in the ICF and in accordance with 
Section 9.5.2.1, to notify study center personnel of any AEs occurring during the 30-day 
poststudy period. Any AEs reported by the patient (or patient representative) during this 
period are to be recorded in original source documents. AEs are also to be recorded in the 
eCRF if at least one of the following conditions is met: 1) the event meets the criteria for 
an SAE (see Sections 9.5.2.1.3 and 9.5.2.1.4), and/or 2) the event is judged by the 
investigator to be potentially causally related to IP (Section 9.5.2.1.1).


Naurex, Inc.
51
RAP-MD-33 Protocol Final
02 May 2018
Any AEs that are ongoing at the time of the final protocol-defined study visit will be 
followed until the condition returns to prestudy status, has resolved or stabilized, or can 
be explained as being unrelated to the IP. 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.
9.5.2.2
Immediate Reporting of 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, the 
study center personnel must report the event to Global Drug Safety on the SAE Form for 
Clinical Trials. The Study Physician may also be notified by telephone.
If, during follow-up, any nonserious AE worsens and eventually meets the criteria for an 
SAE, that AE should be recorded as a new SAE. 
The study center must transmit the SAE Form for Clinical Trials to the SAE email 
address or fax number shown below. Even if an initial report is made by telephone, the 
SAE Form for Clinical Trials completed with 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 are to be followed by 
the study staff until resolution or until the SAE is deemed stable. The sponsor may 
contact the study center to solicit additional information or follow up on the event.

9.5.2.3
Reporting of Pregnancies Occurring During the Study
Study center personnel must report every pregnancy from the time the patient signs the 
ICF until 30 days after the last dose of IP. Within 24 hours of learning of the pregnancy, 
the study center personnel must report the event to Global Drug Safety on the Clinical 
Trial Pregnancy Form and email or fax it to the SAE/Pregnancy email address or fax 
number provided in Section 9.5.2.2, even if no AE has occurred. Pregnancies in female 
partners of male patients occurring during the time frame described above must also be 
reported. 
Any pregnancy of a patient treated with IP must be followed to term and the outcome 
reported by completing a follow-up Clinical Trial Pregnancy Form. If the pregnancy is 
associated with an SAE (eg, if the mother is hospitalized for hemorrhage), a separate 
SAE Form for Clinical Trials must be filed as described in Section 9.5.2.2, with the 
appropriate serious criterion (eg, hospitalization) indicated in addition to the pregnancy 
form.

DATA QUALITY ASSURANCE
9.6.1
Data Monitoring
Before any patient enters the study, a representative of the sponsor will meet with the 
investigator and the study center staff 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. After the first patient is enrolled, the sponsor
representative, a Regional Site Manager or designee, will periodically monitor the 
progress of the study by conducting on-site visits. This Regional Site Manager or 
designee will review query statuses remotely, possibly warranting more frequent 
communication and/or study center visits with the investigator and the study center staff. 
The investigator will make available to the Regional Site Manager or designee source 
documents (written notes and electronic medical records, if used), signed consent forms, 
and all other study-related documents. The investigator and the study center staff will be 
responsible for data entry of patient data into the eCRFs via the EDC system, resolving 
data queries generated via the EDC system and providing missing or corrected data. 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.
9.6.2
Data Recording and Documentation
Data collection will involve the use of the EDC system, to which only authorized 
personnel will have access. Patient’s data are to be entered into the EDC system by the 
investigator or designee using their assigned EDC user account. 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.
After all data have been reviewed and all issues have been resolved, the database will be 
locked.


Naurex, Inc.

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, 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.
 
. Source documents 
will be used at the study centers and may include a patient’s medical record, hospital 
charts, clinic charts, the investigator’s patient study files, as well as the results of 
diagnostic tests such as laboratory tests, ECGs, etc. A centralized clinical laboratory will 
be used for the analysis of all blood samples. Additional information on the collection 
and handling of samples is detailed in the Lab Procedure Manual.

9.7.1.4
Double-Blind Modified Intent-to-Treat Population
The Double-blind modified Intent-to-Treat (Double-blind mITT) Population will consist 
of all patients in the Double-blind Safety Population who had at least 1 
postrandomization assessment of the MADRS or the CGI-S during the DBTP of the 
study.
9.7.1.5
Pharmacokinetic Population
The PK Population will consist of all patients in the Safety Population with at least 1 
evaluable PK sample.
9.7.2
Patient Disposition
The number and percentage of patients who entered the OLTP, who prematurely 
discontinued from the OLTP, who completed the OLTP, who met or did not meet the 
criteria to enter the DBTP at the end of the OLTP, and who entered the DBTP will be 
summarized overall and by reasons for premature discontinuation for all enrolled patients 
in the OLTP. Similarly, the number and percentage of patients who completed the DBTP 
and who prematurely discontinued from the DBTP will be summarized overall, by 
double-blind treatment group, and by reasons for premature discontinuation for the all 
randomized patients in the DBTP.
9.7.3
Demographics and Other Baseline Characteristics
Demographic parameters and other baseline characteristics (eg, age, race, ethnicity, sex, 
weight, height, body mass index) will be summarized overall for the Open-label mITT
Populations and by treatment group for the Double-blind modified ITT population. 
9.7.4
Extent of Exposure and Treatment Compliance
9.7.4.1
Extent of Exposure
Exposure to open-label rapastinel for the Open-label Safety Population during the OLTP
will be summarized for treatment duration, calculated as the number of days from the 
date of the first dose of open-label rapastinel taken to the date of the last dose taken 
during the OLTP, inclusive. Descriptive statistics (number of patients, mean, SD, 
minimum, median, and maximum) will be presented.
Exposure to double-blind IP for the Double-blind Safety Population during the DBTP 
will be summarized for treatment duration, calculated as the number of days from the 
date of the first dose of double-blind IP taken to the date of the last dose taken during the 
DBTP, inclusive. Descriptive statistics (number of patients, mean, SD, minimum, 
median, and maximum) will be presented by treatment group.

9.7.4.2
Prior and Concomitant Medication
Prior medication is defined as any medication started before the date of first dose of 
open-label IP. Concomitant medication during the OLTP is defined as any medication 
taken on or after the date of the first dose of open-label IP during the OLTP. Concomitant 
medication during the DBTP will be defined as any medication taken on or after the date 
of the first dose of double-blind IP.
The use of prior medication will be summarized by the number and percentage of patients 
receiving each medication within each therapeutic class for the Open-label Safety 
Population. The use of concomitant medications during the OLTP will be summarized by 
the number and percentage of patients receiving each medication within each therapeutic 
class for the Open-label Safety Population. The use of concomitant medications during 
the DBTP will be summarized by treatment group by the number and percentage of 
patients receiving each medication within each therapeutic class for the Double-blind 
Safety Population. Multiple use of the same medication by a patient will only be counted 
once.
9.7.4.3
Measurement of Treatment Compliance
Dosing compliance for a specified period will be defined as the total number of IV doses 
actually taken by a patient during that period divided by the number of IV doses that were 
expected to be taken during the same period multiplied by 100. The total number of IV 
doses actually taken during a specific time period is calculated as the sum of IV doses 
taken during that period as obtained from the study medication record. The number of IV 
doses expected to be taken for a specific treatment period will be the number of weeks in 
that period. 
Descriptive statistics for open-label IP compliance will be presented for the OLTP for the 
Open-label Safety Population. Descriptive statistics for double-blind IP compliance will 
be presented by treatment group for the DBTP for the Double-blind Safety Population.
9.7.5
Efficacy Analyses
All efficacy analyses for the OLTP will be performed using the Open-label mITT 
Population. All efficacy analyses for the DBTP will be performed using the Double-blind 
mITT Population. The baseline of the lead-in study will be used as the baseline for the
OLTP and the DBTP. All statistical tests will be 2-sided hypothesis tests performed at the 
5% level of significance and all confidence intervals (CIs) will be 2-sided 95% CIs, 
unless stated otherwise.
An additional analysis plan specific to European Medicines Agency will be presented in a 
stand-alone document.

9.7.5.1
Primary Efficacy Analyses
The primary efficacy parameter is the time to first relapse during the 52 weeks of the 
DBTP, defined as the number of days from the randomization date of DBTP to the 
relapse date during the 52 weeks of the DBTP. Relapse during the DBTP is defined as 
meeting any of the following criteria:

MADRS total score ≥ 18 at 2 consecutive visits

≥ 2 increase in CGI-S score compared with that obtained at randomization

Risk of suicide as determined by the investigator

Need for hospitalization due to worsening of depression as determined by the 
investigator

Need for alternative treatment of depressive symptoms as determined by the 
investigator 
For patients who did not meet the above relapse criteria during the 52 weeks of the 
DBTP, the time to relapse will be censored at the time of completion or discontinuation 
from the study, or 52 weeks, whichever is earlier.
The primary efficacy analysis will compare the time to first relapse between placebo and 
rapastinel treatment groups in the respective time-frame (within the 52 weeks of the 
DBTP) using the log-rank test. The primary null hypothesis is that the distribution of the 
time to relapse for each of the rapastinel treatment groups is not different from that for 
the placebo treatment group. 
Estimates of the hazard ratio and 95% CI will be based on the Cox proportional hazards 
model with treatment group as an explanatory variable. The cumulative distribution 
function of time to relapse will be characterized by the Kaplan-Meier curves.
The Hochberg procedure will be used to control the overall type I error rate at the 0.05 
level for comparisons between each of rapastinel treatment groups and the placebo.

Adverse Events
AEs will be coded by system organ class (SOC) and preferred term using the Medical 
Dictionary for Regulatory Activities.
An AE (classified by preferred term) that occurs during the OLTP or thereafter will be 
considered a treatment-emergent adverse event (TEAE) if it was not present before the 
date of the first dose of IP in the OLTP or was present before the first dose of IP in the 
OLTP and increased in severity during the OLTP or thereafter. If more than 1 AE is 
reported before the date of the first dose of IP in the OLTP and coded to the same 
preferred term, the AE with the greatest severity will be used as the benchmark for 
comparison with the AEs occurring during the OLTP that were also coded to that 
preferred term.
An AE (classified by preferred term) that occurs during the DBTP of the study will be 
considered a newly emergent adverse event (NEAE) if the AE was not present before the 
first dose of the double-blind IP or it was present before the first dose of the double-blind 
IP and increased in severity during the DBTP. If more than 1 AE is reported before the 
first dose of the double-blind IP and coded to the same preferred term, the AE with the 
greatest severity will be used as the benchmark for comparison with the AEs occurring 
during the DBTP that were also coded to that preferred term. An AE that occurs more 
than 30 days after the date of the last dose of IP will not be counted as a NEAE.

tabulated by SOC and preferred term. Similarly, the number and percentage of patients 
reporting NEAEs during the DBTP will be tabulated by SOC and preferred term. The 
number and percentage of patients in each treatment group reporting TEAEs and NEAEs 
during the DBTP will be tabulated by SOC and preferred term; by SOC, preferred term, 
and severity; and by SOC, preferred term, and causal relationship to the IP. If more than 
1 AE is coded to the same preferred term for the same patient during the same treatment 
period, the patient will be counted only once for that preferred term using the most severe 
and most related occurrence for the summarization by severity and by causal relationship 
to the IP.
The distribution of TEAEs and NEAEs by severity and relationship to the IP will be 
summarized for each treatment group for the DBTP.
The incidence of common (≥ 2% of patients in any treatment group) TEAEs and NEAEs 
during the DBTP will be summarized by preferred term and treatment group and will be 
sorted by decreasing frequency for the weekly rapastinel group. 
An SAE that occurred between the date of the first dose of the open-label IP and 30 days 
after the date of the last dose of double-blind IP, inclusive, will be considered an on-
therapy SAE. The number and percentage of patients who had on-therapy SAEs during 
the OLTP will be summarized by preferred term and sorted by decreasing frequency. The 
number and percentage of patients who had on-therapy SAEs during the DBTP will be 
summarized by treatment group and preferred term and will be sorted by decreasing 
frequency for the weekly rapastinel group.
The number and percentage of patients who had fatal on-therapy SAEs during the OLTP
will be summarized by preferred term and sorted by decreasing frequency. The number 
and percentage of patients who had fatal on-therapy SAEs during the DBTP will be 
summarized by treatment group and preferred term and sorted by decreasing frequency 
for the weekly rapastinel group.
The incidence of TEAEs leading to premature discontinuation of IP during the OLTP will 
be summarized by preferred term and will be sorted by decreasing frequency. The 
incidence of TEAEs and NEAEs leading to premature discontinuation of IP during the 
DBTP will be summarized by preferred term and treatment group and will be sorted by 
decreasing frequency for the weekly rapastinel group.
Listings will be presented for all patients with SAEs, patients with AEs leading to 
discontinuation, and patients who died (if any).

Determination of Sample Size
The sample size and power calculations are based on the analysis of time to relapse 
during the 52 weeks of the DBTP. Assuming a relapse rate of 19% per 26 weeks in the 
placebo group and a dropout rate of 20% per 26 weeks in all treatment groups, the sample 
size of 200 per group will have 90% power to detect a hazard ratio of 0.475 for a
rapastinel treatment versus placebo at a 0.05 significance level. To achieve this number 
of randomized patients, approximately 1400 patients need to be enrolled in this study if 
50% of patients are qualified for randomization.
9.7.11
Statistical Software
Statistical analyses will be performed using version 9.3 (or newer) of SAS.
9.8
DATA AND SAFETY MONITORING BOARD
The study will be conducted under the supervision of an independent DSMB to be 
chartered to review safety data at predetermined points during the study. The DSMB may 
also decide to meet and review safety data at other time points should it be deemed 
necessary. The DSMB is responsible for the ongoing review of safety data in the clinical 
study and for making recommendations concerning the continuation, modification, and 
termination of the study (FDA Guidance for Clinical Trial Sponsors: Establishment and 
Operation of Clinical Trial Data Monitoring Committees, March 2006; European 
Medicines Agency Guideline on Data Monitoring Committees, 
EMEA/CHMP/EWP/5872/03, July 2005).
All analyses that are required to support the DSMB will be performed by independent
statistician(s) not otherwise involved in the study. Details of the DSMB membership, 
meeting schedule, and data review and analysis will be documented in the DSMB 
Charter.
9.9
CHANGES IN THE CONDUCT OF THE STUDY OR PLANNED 
ANALYSES
Any amendment to this protocol will be provided to the investigator in writing by the 
sponsor. No protocol amendment may be implemented (with the exceptions noted below) 
before it has been approved by the IRB/EC and other applicable oversight bodies and the 
signature page, signed by the investigator, and 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/EC review and approval in jurisdictions where regulatory 
authorities allow such implementation. However, the IRB/EC must be informed in 
writing of such an amendment, and approval must be obtained within reasonable time 
limits.

If unclarities arise with regard to interpretation or conduct of the approved protocol 
during the conduct of the study, the sponsor will provide guidance in the form of a 
protocol clarification letter.  Such guidance will be used to clarify only within the bounds 
of the approved protocol.
9.10
PROTOCOL DEVIATIONS
A protocol deviation is any change, divergence, or departure from the study design or 
procedures that is under the investigator’s responsibility and oversight (as defined by 
regulations) without prior written IRB/EC approval or favorable opinion of an 
appropriate amendment and that does not have a major impact on the patient’s rights, 
safety, or well-being, or on the integrity and authenticity of the study data. Deviations 
may include, but are not limited to, departure from inclusion/exclusion criteria, dosing, 
duration of treatment, failure to perform the required assessments at specified time points, 
scheduling of visits not in accordance with specifications, or patient safety. Deviating 
from the protocol is permitted only if absolutely necessary for the safety or clinical 
management of the patients and must immediately be reported to the sponsor.
A significant protocol deviation is a form of protocol deviation that has a major impact 
on the patient’s rights, safety, or well-being, or on the integrity and authenticity of the 
study data. The IRB/EC must be notified within the time period dictated by the IRB/EC
associated with this study.

INTRODUCTION 
This Statistical Analysis Plan (SAP) describes the methodology that will be used to 
summarize the statistical analyses of the efficacy and safety data for the final protocol of 
Study RAP-MD-33 (version dated 02MAY2018).  
Study RAP-MD-33 is a Phase 3, multicenter, randomized-withdrawal, parallel-group, 
placebo-controlled, maintenance study to evaluate the efficacy, safety, and tolerability of 
rapastinel in the prevention of relapse in patients with major depressive disorder (MDD) 
who completed one of the rapastinel lead-in studies including RAP-MD-30 and RAP-
MD-32.  The RAP-MD-31 study was terminated before any patient was enrolled.  Thus, 
there is no patient rolled-over from the RAP-MD-31 study to RAP-MD-33 study.  
The study will be conducted in the following periods: 
 An 8- to 16-week open-label treatment period (OLTP) where patients receive 
rapastinel 225 or 450 mg IV weekly 
 A randomized double-blind treatment period (DBTP) of at most 52 weeks of 
treatment duration where patients are randomized 1:1:1 to either rapastinel 225 or 450 
mg weekly, rapastinel clinically driven schedule (IV, 225 or 450 mg, variable 
interval, placebo on intervening weeks) or placebo 
 A 2-week safety follow-up period 
In order for patients to transition from the OLTP and be randomized into the DBTP, the 
patient must meet the stability criterion sometime after 8 weeks (and up to 16 weeks) 
during the OLTP.  A patient will be considered a stable responder upon achieving both 
criteria (1) and (2) below: 
1) An observed Montgomery-Asberg Depression Rating Scale (MADRS) total score 
≤ 12 with no more than one modest MADRS excursion (MADRS total score > 12 
but ≤ 16) for at least six consecutive weeks.   
2) An observed MADRS total score ≤ 12 for at least two consecutive visits prior to 
randomization.   
The OLTP starts with the first dose of open-label treatment and ends with one of the 
following: the first dose of double-blind treatment for patients who enter the DBTP or 
Visit 69/Week 52 End-of-Treatment/Early Termination (ET) assessments for patients 
who do not enter the DBTP. 
The double-blind treatment period starts when the first dose of double-blind treatment is 
administered and ends when the patient meets relapse criteria, completes 52 weeks of 
double-blind treatment, or discontinues for other reasons.

The safety follow-up (SFU) period starts after completion of the last scheduled 
assessment (or ET) and ends with the last available assessment. 
Individual treatment durations will vary. The maximum duration of the study will be 
70 weeks.

OBJECTIVES 
 The objective of this study is to evaluate the efficacy, safety, and tolerability of 
rapastinel relative to placebo in the prevention of relapse in patients with MDD.   
Efficacy Objectives 
 Primary efficacy objective: To evaluate the efficacy of rapastinel (225 or 450 mg IV 
weekly or clinically driven schedule) versus placebo in the maintenance treatment of 
MDD as a monotherapy, as measured by time to relapse during the first 52 weeks of 
the DBTP.

DEMOGRAPHICS AND BASELINE CHARACTERISTICS 
Demographic parameters (e.g., age, race, ethnicity, sex,) and baseline characteristics 
(e.g., weight, height, body mass index) will be summarized overall for the Open-label 
mITT Populations and by treatment group for the Double-blind modified ITT population.  
Medical and surgical history during the past 12 months and psychotropic medication 
history during the previous 5 years will be coded using the Medical Dictionary for 
Regulatory Activities (MedDRA), version 21.0 or newer. Data will be presented in 
listings for the Open-label Safety Population. 
Psychiatric history will be summarized overall for the Open-label mITT Populations and 
by treatment group for the Double-blind modified ITT population. 
Prior medication is defined as any medication started before the date of first dose of 
open-label IP. Concomitant medication during the OLTP is defined as any medication 
taken on or after the date of the first dose of open-label IP during the OLTP. Concomitant 
medication during the DBTP will be defined as any medication taken on or after the date 
of the first dose of double-blind IP. 
Prior and concomitant medications during the OLTP will be listed for the Open-label 
Safety Population. Concomitant medications during the DBTP will be listed for the 
Double-blind Safety Population. Concomitant medications started after the patient’s last 
study visit during their last treatment period will be presented in the data listings. 
The World Health Organization Drug Dictionary Enhanced (WHODDE) will be used to 
classify prior and concomitant medications by therapeutic class and drug name.

EXTENT OF EXPOSURE AND TREATMENT COMPLIANCE 
7.1 
EXTENT OF EXPOSURE 
Exposure to open-label rapastinel for the Open-label Safety Population during the OLTP 
will be summarized for treatment duration, calculated as the number of days from the 
date of the first dose of open-label rapastinel taken to the date of the last dose taken 
during the OLTP, inclusive. Descriptive statistics will be presented. 
Exposure to double-blind IP for the Double-blind Safety Population during the DBTP 
will be summarized for treatment duration, calculated as the number of days from the 
date of the first dose of double-blind IP taken to the date of the last dose taken during the 
DBTP, inclusive. Descriptive statistics will be presented by treatment group. 
The number of IV doses of rapastinel administered to each patient during the OLTP will 
be summarized using descriptive statistics for the Open-label Safety Population.

EFFICACY ANALYSES 
8.1 
PRIMARY EFFICACY PARAMETERS 
The analysis of the primary efficacy parameter will be performed using the Double-blind 
mITT Population.  
The primary efficacy parameter is the time to first relapse during the 52 weeks of the 
DBTP, defined as the number of days from the randomization date of DBTP to the 
relapse date (ie., relapse date – randomization date + 1). Relapse during the DBTP is 
defined as meeting any of the following criteria: 
 Rater-administered MADRS total score ≥ 18 at 2 consecutive visits 
 ≥ 2 increase in CGI-S score compared with that obtained at randomization 
 Risk of suicide as determined by the investigator 
 Need for hospitalization due to worsening of depression as determined by the 
investigator 
 Need for alternative treatment of depressive symptoms as determined by the 
investigator 
Patients who did not meet the above relapse criteria during the 52 weeks of the DBTP, 
the time to relapse will be censored at the time of completion or discontinuation from the 
study, or 52 weeks, whichever is earlier. 
The primary efficacy analysis will be presented by the cumulative distribution function of 
time to relapse characterized by the Kaplan-Meier curve for each treatment group.

9.1 
ADVERSE EVENTS 
AEs will be coded using the Medical Dictionary for Regulatory Activities. 
An AE (classified by preferred term) that occurs during the OLTP or thereafter will be 
considered a treatment-emergent adverse event (TEAE) if it was not present before the 
date of the first dose of IP in the lead-in study or was present before the first dose of IP in 
the lead-in study and increased in severity during the OLTP or thereafter.  An AE that 
becomes serious during the OLTP or thereafter will also be considered as TEAE.  If more 
than 1 AE is reported before the date of the first dose of IP in the lead-in study and coded 
to the same preferred term, the AE with the greatest severity will be used as the 
benchmark for comparison with the AEs occurring during the OLTP or thereafter that 
were also coded to that preferred term.  An AE that occurs more than 30 days after the 
date of the last dose of IP will not be counted as a TEAE. 
An AE (classified by preferred term) that occurs during the OLTP of the study will be 
considered a newly emergent adverse event (NEAE) if the AE was not present before the 
first dose of IP in the OLTP or it was present before the first dose of IP in the OLTP and 
increased in severity during the OLTP.  An AE that becomes serious during the OLTP 
will also be considered as NEAE.  If more than 1 AE is reported before the first dose of 
IP in the OLTP and coded to the same preferred term, the AE with the greatest severity 
will be used as the benchmark for comparison with the AEs occurring during the OLTP 
that were also coded to that preferred term.

An AE (classified by preferred term) that occurs during the DBTP of the study will be 
considered a newly emergent adverse event (NEAE) if the AE was not present before the 
first dose of IP in the DBTP or it was present before the first dose of IP in the DBTP and 
increased in severity during the DBTP.  An AE that becomes serious during the DBTP 
will also be considered as NEAE.  If more than 1 AE is reported before the first dose of 
IP in the DBTP and coded to the same preferred term, the AE with the greatest severity 
will be used as the benchmark for comparison with the AEs occurring during the DBTP 
that were also coded to that preferred term.  
An AE (classified by preferred term) that occurs during the SFU of the study will be 
considered a newly emergent adverse event (NEAE) if the AE was not present before or 
at Visit 70 or it was present before or at Visit 70 and increased in severity during the 
SFU. An AE that becomes serious during the SFU will also be considered as NEAE. If 
more than 1 AE is reported before or at Visit 70 and coded to the same preferred term, 
the AE with the greatest severity will be used as the benchmark for comparison with the 
AEs occurring during the SFU that were also coded to that preferred term.  
An AE that occurs more than 30 days after the date of the last dose of IP will not be 
counted as an NEAE. 
An SAE that occurred between the date of the first dose of IP in the OLTP and 30 days 
after the date of the last dose of IP, inclusive, will be considered a treatment-emergent 
SAE (e.g., TESAE). 
The overall number and percentage of patients with TEAEs, NEAEs, death, TESAEs, 
TEAEs leading to study discontinuation and TEAEs related to study drug during the 
OLTP will be tabulated overall, and during the DBTP and the SFU by treatment group. 
The incidence of common (≥ 2% of patients in any treatment group) TEAEs and NEAEs 
during the OLTP will be summarized overall by preferred term.  Similarly, the incidence 
of common TEAEs and NEAEs during the DBTP and during the SFU will be 
summarized by preferred term and treatment group and will be sorted by decreasing 
frequency starting with the weekly rapastinel group followed by the clinically driven 
schedule rapastinel group.  
Listings will be presented for all patients with AEs and patients who died (if any).

DETERMINATION OF SAMPLE SIZE 
The sample size and power calculations are based on the analysis of time to relapse 
during the first 52 weeks of the DBTP. Assuming a relapse rate of 19% per 26 weeks in 
the placebo group and a dropout rate of 20% per 26 weeks in all treatment groups, the 
sample size of 200 per group will have 90% power to detect a hazard ratio of 0.475 for a 
rapastinel treatment versus placebo at a 0.05 significance level. To achieve this number 
of randomized patients, approximately 1400 patients need to be enrolled in this study if 
50% of patients are qualified for randomization.

b Dosing visit is the nominal visit reported in CRF. During the OLTP a patient is scheduled to receive the 1st dose on 
day 0 (Visit 1), the 2nd dose at week 1, and will be weekly administered until week 16. If a patient skipped a 
scheduled re-treatment dosing at a week, the dosing date will be treated as missing for that week. During the DBTP 
a patient is schedule to receive the 1st dose on day 0 (Visit 17), the 2nd dose at week 1, and will be weekly 
administered until relapse criteria are met or for up to 52 weeks (Visit 69) or study termination.

If a patient has 2 or more values for a given endpoint within the same window, the value 
with collection date closest to the scheduled day will be used for analysis; if there are 2 
values whose collection dates are equidistant from the scheduled day, the value 
corresponding to the later date will be used for analysis. 
With the exception of endpoints recorded pre or post IP dose and Visit 69/ET MADRS 
assessments, in the event there are multiple values of the same endpoint on the same date, 
the last value will be taken as the value for that date.  For endpoints reported pre IP dose, 
in the event there are multiple values of the same endpoint prior to IP dose, the last value 
prior to the IP dose is taken as the pre-dose value for that date.  Similarly, for endpoints 
reported post IP dose, in the event there are multiple values of the same endpoint after IP 
dose, the last value will be taken as the post-dose value for that date.  For multiple 
MADRS assessments on the same date for Visit 69/ET, the last MADRS assessment prior 
to Visit 69/ET on that date will be taken as the value for that date.

The first relapse date for a patient is defined as the earliest assessment date in which any 
of the relapse criteria mentioned above were met, obtained either from the date recorded 
on the Relapse CRF (for the primary reasons of “Risk of Suicide”, “Need for 
hospitalization due to worsening of depression” or “Need for alternative treatment for 
depressive symptoms”) or the dates of the corresponding MADRS or CGI-S assessments. 
For the relapses based on MADRS total score ≥ 18 at 2 consecutive visits, the relapse 
date is defined as the assessment date of the first visit of the 2 consecutive assessments.  
14.4 
REPEATED OR UNSCHEDULED ASSESSMENTS OF SAFETY 
PARAMETERS 
If end-of-study assessments are repeated or if unscheduled visits occur, the last non-
missing postbaseline assessment will be used as the end-of-study assessment for 
generating summary statistics. However, all postbaseline assessments will be used for 
PCS value determinations, and all assessments will be presented in the data listings. 
14.5 
MISSING SEVERITY ASSESSMENT FOR ADVERSE EVENTS 
If severity is missing for an AE that started before the date of the first dose of open-label 
IP, an intensity of mild will be assigned. If severity is missing for an AE that started on or 
after the date of the first dose of open-label IP, a severity of severe will be assigned. The 
imputed values for severity assessment will be used for the incidence summary; the 
values will be shown as missing in the data listings. 
14.6 
MISSING CAUSAL RELATIONSHIP TO STUDY DRUG FOR 
ADVERSE EVENTS 
If the causal relationship to the IP is missing for an AE that started on or after the date of 
the first dose of open-label IP, a causality of yes will be assigned. The imputed values for 
causal relationship to randomized treatment will be used for the incidence summary; the 
values will be shown as missing in the data listings. 
14.7 
MISSING DATE INFORMATION FOR ADVERSE EVENTS 
The following imputation rules only apply to cases in which the start date for an AE is 
incomplete (ie, partly missing).

Missing month and day 
 If the year of the incomplete start date is the same as the year of the first dose of 
open-label IP, the month and day of the first dose of open-label IP will be assigned to 
the missing fields. 
 If the year of the incomplete start date is before the year of the first dose of open-label 
IP, 31 Dec will be assigned to the missing fields. 
 If the year of the incomplete start date is after the year of the first dose of open-label 
IP, 01 Jan will be assigned to the missing fields. 
Missing month only 
 If only the month is missing, the day will be treated as missing and both the month 
and the day will be replaced according to the above procedure. 
Missing day only 
 If the month and year of the incomplete start date are the same as the month and year 
of the first dose of open-label IP, the day of the first dose of open-label IP will be 
assigned to the missing day. 
 If either the year of the incomplete start date is before the year of the date of the first 
dose of open-label IP or if both years are the same, but the month of the incomplete 
start date is before the month of the date of the first dose of open-label IP, the last day 
of the month will be assigned to the missing day. 
 If either the year of the incomplete start date is after the year of the date of the first 
dose of open-label IP or if both years are the same, but the month of the incomplete 
start date is after the month of the date of the first dose of open-label IP, the first day 
of the month will be assigned to the missing day. 
If the stop date is complete and the imputed start date as above is after the stop date, the 
start date will be imputed by the stop date. 
If the start date is completely missing and the stop date is complete, the following 
algorithm will be used to impute the start date: 
 If the stop date is after the date of the first dose of open-label IP, the date of the first 
dose of open-label IP will be assigned to the missing start date. 
 If the stop date is before the date of the first dose of open-label IP, the stop date will 
be assigned to the missing start date.

MISSING DATE INFORMATION FOR PRIOR OR 
CONCOMITANT MEDICATIONS 
For prior or concomitant medications, including background ADT, incomplete 
(i.e. partially missing) start dates and/or stop dates will be imputed. When the start date 
and the stop date are both incomplete for a patient, the start date will be imputed first.  
14.8.1 
Incomplete Start Date 
The following rules will be applied to impute the missing numeric fields for an 
incomplete prior or concomitant medication start date. If the stop date is complete (or 
imputed) and the imputed start date is after the stop date, the start date will be imputed 
using the stop date. 
Missing month and day 
 If the year of the incomplete start date is the same as the year of the first dose of 
open-label IP, the month and day of the first dose of open-label IP will be assigned to 
the missing fields. 
 If the year of the incomplete start date is before the year of the first dose of open-label 
IP, 31 Dec will be assigned to the missing fields. 
 If the year of the incomplete start date is after the year of the first dose of open-label 
IP, 01 Jan will be assigned to the missing fields. 
Missing month only 
 If only the month is missing, the day will be treated as missing and both the month 
and the day will be replaced according to the above procedure. 
Missing day only 
 If the month and year of the incomplete start date are the same as the month and year 
of the first dose of open-label IP, the day of the first dose of open-label IP will be 
assigned to the missing day. 
 If either the year of the incomplete start date is before the year of the date of the first 
dose of open-label IP or if both years are the same, but the month of the incomplete 
start date is before the month of the date of the first dose of open-label IP, the last day 
of the month will be assigned to the missing day.

dose of open-label IP or if both years are the same, but the month of the incomplete 
start date is after the month of the date of the first dose of open-label IP, the first day 
of the month will be assigned to the missing day. 
14.8.2 
Incomplete Stop Date 
The following rules will be applied to impute the missing numeric fields for an 
incomplete prior or concomitant medication stop date.  If the imputed stop date is before 
the start date (imputed or non-imputed start date), the imputed stop date will be equal to 
the start date. 
Missing month and day 
 If the year of the incomplete stop date is the same as the year of the later of the date 
of the last dose of open-label IP and the date of last dose of double-blind IP, the 
month and day of the later of the date of the last dose of open-label IP and the date of 
last dose of double-blind IP will be assigned to the missing fields. 
 If the year of the incomplete stop date is before the year of the later of the date of the 
last dose of open-label IP and the date of last dose of double-blind IP, 
December 31 will be assigned to the missing fields. 
 If the year of the incomplete stop date is after the year of the later of the date of the 
last dose of open-label IP and the date of last dose of double-blind IP, January 1 will 
be assigned to the missing fields. 
Missing month only 
 If only the month is missing, the day will be treated as missing and both the month 
and the day will be replaced according to the above procedure. 
Missing day only 
 If the month and year of the incomplete stop date are the same as the month and year 
of the later of the date of the last dose of open-label IP and the date of last dose of 
double-blind IP, the day of the later of the date of the last dose of open-label IP and 
the date of last dose of double-blind IP will be assigned to the missing day. 
 If either the year of the incomplete stop date is before the year of the later of the date 
of the last dose of open-label IP and the date of last dose of double-blind IP or if both 
years are the same but the month of the incomplete stop date is before the month of 
the date of the later of the date of the last dose of open-label IP and the date of last 
dose of double-blind IP, the last day of the month will be assigned to the missing day.
