INTRODUCTION
Disease Burden of Major Depressive Disorder
Major depressive disorder (MDD) is a highly disabling, serious condition that 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 associated with suicide and 
4 million of the disability adjusted life years 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 that is a leading cause of disability in the world.

Disease Burden of Suicidality
Suicidality is a complex multifactorial public health problem with far-reaching 
consequences for individuals and families, as well as significant impacts on society at 
large.  Suicide is the 10th leading cause of death in the United States, and each year over 
40,000 die by suicide in the United States (Centers for Disease Control and Prevention. 
2017).  It is estimated that suicide costs the United States $51 billion annually (Centers 
for Disease Control and Prevention, 2010).  Approximately 7% of the US population 
knew someone who died by suicide during the past 12 months (Berman, 2011) and these 
survivors are deeply impacted psychologically (Brent, 2010).  Suicide rates have 
increased from 1999 through 2014 with greater increases since 2006, indicating that the 
impact of suicide is growing over time (Curtin et al, 2016).  Suicidal ideation and 
behavior is a common comorbidity across the spectrum of mental health disorders 
although it is strikingly associated with mood disorders, particularly MDD.  Depression is 
the psychiatric diagnosis most commonly associated with suicide and approximately 2% 
to 9% of patients with a lifetime diagnosis of depression die of suicide (Bostwick and 
Pankratz, 2000; Nock et al, 2010).
Rationale for Rapastinel as a Rapid Treatment of Symptoms of Depression and 
Suicidality in MDD
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 demonstrated antidepressant properties in relevant 
animal models, displayed cognitive enhancing properties in treated animals, and 
facilitated 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 hypothesized to produce its long-lasting antidepressant 
effects via triggering NMDAR-dependent processes that lead to increased sensitivity to 
LTP that persist for up to 2 weeks (Burgdorf et al, 2015).
In 2 Phase 2 clinical studies in patients with MDD, single intravenous (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, ketamine 
produced a rapid, yet transient, antidepressant effect, accompanied by brief 
psychotomimetic and dissociative effects. However, rapastinel significantly reduced 
depressive symptoms with a much lower propensity for psychotomimetic or dissociative 
effects (Newport et al, 2015).

16
Naurex
RAP-MD-20 Protocol
26 Sep 2017
Naurex, Inc initially developed rapastinel as a treatment for patients with MDD who 
manifest a serious and common aspect of the disease: inadequate response to existing 
antidepressant therapy. In Phase 2 studies, single doses of 5 or 10 mg/kg showed rapid 
antidepressant effects, with a large effect detected after 1 day.  Repeated doses 
demonstrated a rapid, sustained antidepressant effect and were well tolerated with 
adjunctive treatment in patients with partial responses to their antidepressants. To date, 
rapastinel has been shown to be safe and well tolerated and the observed safety of 
rapastinel is significantly better than that of NMDAR antagonists, which induce 
psychotomimetic side effects and have abuse/diversion potential.  Rapastinel showed a 
low propensity to induce psychotomimetic side effects or effects that might predict abuse 
potential.  The available clinical data also suggest that rapastinel is not associated with
the serious metabolic and extrapyramidal side effects seen with the atypical 
antipsychotics currently approved for adjunctive treatment of MDD.
The efficacy of rapastinel is consistent with that observed in several other studies 
utilizing NMDAR modulators (such as ketamine).  Such NMDAR modulating drugs are 
increasingly being recognized as having potential as treatments for suicidality (Griffiths 
et al, 2014; Reinstatler and Youssef, 2015; Price and Matthew, 2015). Multiple small 
studies have been undertaken with ketamine (Burger et al, 2016; De Gioannis et al, 2014; 
Lee et al, 2015) and esketamine has entered late stage clinical trials (NCT03039192; 
NCT03097133) targeting suicidality after promising proof-of-concept results (Canuso et 
al, 2016a; Canuso et al, 2016b).  Of interest are recent indicators that the anti-suicidality 
effects of ketamine may be due at least in part to procognitive effects (Price et al, 2009; 
Price et al, 2014).  Preclinical data indicate that rapastinel has strong procognitive effects 
which has led to suggestions from experts that the study of rapastinel for suicidality is 
warranted (Lee et al, 2016).  The rapid onset of efficacy and favorable safety profile seen 
with rapastinel provide a compelling rationale for evaluating its potential for rapid 
treatment of symptoms of depression and suicidality in MDD.
The purpose of this study is to prospectively confirm that rapastinel, when administered 
along with standard of care (SOC) at a dose of 450 mg as a short IV infusion in adult 
patients with MDD who are at imminent risk of suicide, is significantly superior to 
placebo in rapidly reducing symptoms of depression and suicidality. Furthermore, the 
safety and tolerability of rapastinel will be investigated. The study is intended to support 
an application for regulatory approval of rapastinel as a rapid treatment for symptoms of 
depression and suicidality in adult patients with MDD at imminent risk of suicide.

suicidality (see Inclusion Criterion #3).  After providing written consent, patients will 
enter a screening period of no more than 5 days. Every effort should be made to conduct 
all procedures as early as possible in the Screening.  Patients will not receive any 
investigational product (IP) during the screening period. Treatment for suicidality should 
proceed per local SOC with limited restrictions (Section 9.4.9.1).  
Efforts should be made to minimize the length of the Screening Period and proceed to 
randomization or screen failure as rapidly as clinically reasonable. Patients meeting the 
eligibility criteria at Assessment/Visit 2 (Baseline) will be assigned a treatment by the 
interactive web response system (IWRS) and enter the DBTP.  
9.1.2
Double-blind Treatment Period
Patients will be randomized in a ratio of 1:1 to 1 of 2 treatment groups: rapastinel 450 mg 
IV weekly injection or placebo IV weekly injection. During participation in the study, 
patients may be treated per local SOC with limited restrictions (see Section 9.4.9.1) and 
IP will be administered in addition to SOC treatments.

There will be 4 study visits during the first week of the DBTP:

Visit 2: Baseline IP dosing
Note: If Baseline is ≤ 1 day since Screening assessments were conducted, specified 
Baseline assessments do not need to be repeated and Screening assessments will count as 
Baseline (see Section 9.5.5.2 for details).  

Visit 3: 4 hours following the baseline IP dosing

Visit 4: 1 day following the baseline IP dosing

Visit 5: 4 days following the baseline IP dosing
There will be 2 study visits during the second week of the DBTP: 

Visit 6: 7 days following Visit 2

Visit 7: 1 day following Visit 6
There will be 3 weekly study visits during the remainder of the DBTP: 

Visit 8: 14 days following Visit 2

Visit 9: 21 days following Visit 2 

Visit 10: 28 days following Visit 2 
If necessary, study visits may be conducted up to 2 days before or after the scheduled 
visits except for Assessment/Visit 3 (which must be conducted approximately 4 hours 
after Visit 2), Visit 4 (which must be conducted 1 day after Visit 2), and Visit 7 (which 
must be conducted 1 day after Visit 6). All patients who receive IP must complete 
Visit 10 or Early Termination (ET) Visit. 
Generally, it is expected that patients will remain in an inpatient setting until 
approximately 4 days after IP is administered (Visit 5), although this may be adjusted at 
the investigator’s discretion to be shorter or longer to accommodate local SOC based 
upon the patient’s clinical condition.  Patients who require hospitalization for greater than 
14 days (Visit 8) after initial dose of IP should be evaluated regarding other potential 
treatment options and appropriateness of continuing in the study.
Upon completion of the DBTP, patients will enter a 1-week safety follow-up period.

DISCUSSION OF STUDY DESIGN, INCLUDING THE CHOICE 
OF CONTROL GROUPS
This multicenter, randomized, placebo-controlled, parallel-group study with a 4-week 
DBTP, was designed based on prior studies that established rapastinel efficacy and safety 
in adult patients with MDD as well as consideration of the sponsor’s participation in and 
recommendations from a recent International Society for CNS Clinical Trials and 
Methodology Consensus Meeting (Chappell et al, 2017).  The design was further 
developed with the aid of an advisory board conducted on 24 Apr 2017 with participation 
from several recognized experts in the study of suicidality. In this study, investigators 
will enroll patients 18 through 65 years of age who meet the Diagnostic and Statistical 
Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for MDD (American 
Psychiatric Association, 2013). The MDD diagnosis will be confirmed using the Mini 
International Neuropsychiatric Inventory (MINI). The symptoms and severity of MDD 
will be assessed using the MADRS (Section 9.5.1.2.1). The symptoms and severity of 
suicidality will be assessed using the S-STS (Section 9.5.1.2.2).
Allergan has carefully considered the overall study design and setting in light of the 
unique requirements of conducting a clinical trial in this at-risk population. Study centers 
will have experience with the study population and will be encouraged to apply available 
guidelines to minimize patient risk or distress. Because patients will enter the study with 
symptoms of acute suicidality, the study is a partially inpatient design with a required 
initial period of hospitalization of flexible duration intended to accommodate the 
variability of SOC across study centers while ensuring that patients receive appropriate 
monitoring. Patients may enter the study once being admitted to an inpatient setting after 
initially presenting at an emergency room setting or via referral from an outpatient 
healthcare provider, such as a psychiatric private practice or clinic. Generally, it is 
expected that patients will remain in an inpatient setting until approximately 4 days after 
IP is administered, although this may be adjusted at the investigator’s discretion to be 
shorter or longer to accommodate local SOC based upon the patient’s clinical condition.  
Patients who require hospitalization for greater than 14 days after initial dose of IP should 
be evaluated regarding other potential treatment options and appropriateness of 
continuing in the study.
Dose selection information is presented in Section 9.4.5. The planned dosing regimen is 
based on experience from previous rapastinel studies.

Naurex
RAP-MD-20 Protocol
26 Sep 2017
A placebo treatment group is included in the study to comply with worldwide regulatory 
preferences (Laughren, 2001; Gispen-de Wied et al, 2012), since placebo-controlled 
superiority trials have been shown to be conducive to higher-quality studies and to 
provide more reliable outcomes (Feifel, 2008; Laughren, 2001; Gispen-de Wied et al, 
2012). Additionally, from a scientific point of view, randomized double-blind 
comparisons versus placebo are needed to permit adequate evaluation of efficacy. 
Comparison to a placebo treatment is also of value for distinguishing disease 
manifestations from adverse reactions to the IP (EMA guidance, 2013). At present, there 
is no approved pharmacologic therapy as an acute intervention for treatment of symptoms 
of suicidality and depression.  However, patients who present with imminent risk of 
suicide require careful assessment, monitoring, and are typically treated with 
pharmacologic agents based upon their primary diagnosis and comorbidities (Jacobs et al, 
2010).  For this reason, the IP will be given in addition to standard therapy. The use of 
placebo given in addition to standard therapy should not cause irreversible health 
problems or extreme suffering (depression is recognized by the FDA as a condition in 
which there is substantial improvement and variability in placebo groups) (FDA 
Guidance for Industry: E10, May 2001). 
Safety and efficacy assessments are included at every visit to determine adequacy of 
response, safety, and tolerability. In the event of insufficient therapeutic response or 
worsening of the patient’s initial condition, the IP should be discontinued 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).

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 1 of the following reasons:

Screen failure (failure to meet inclusion/exclusion criteria)

Pregnancy

Withdrawal of consent 

AE
o
Any patient who meets any of the following criteria at any point during the 
study must be withdrawn from participation due to suicidality-related AE:
a) A treatment-emergent suicide attempt, interrupted attempt, or aborted 
attempt
b) Significant increase in suicide risk, requiring removal from study as 
judged by the investigator, based on all available information such as
the psychiatric interview or information collected in the study 
assessments
Note: In the event that a patient is withdrawn for a suicidality-related AE, the patient 
should be referred for additional treatment or hospitalization, as clinically indicated, in 
addition to withdrawing the patient from the study.

Lack of efficacy

Protocol deviation

Lost to follow-up 

Study terminated by sponsor


All randomized 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 10. All patients 
discontinuing the study prematurely should enter the 1-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 after each premature discontinuation to ensure proper characterization of 
the reason for discontinuation is captured.
9.3.4
Patient Replacement Procedures
Patients in this study who prematurely discontinue treatment will not be replaced.
9.4
TREATMENTS
Patients meeting the eligibility criteria at the end of Visit 2 (Baseline) will be randomized 
in double-blind fashion to 1 of 2 treatment groups: placebo or rapastinel 450 mg weekly. 
The treatments will be given in a double-blind fashion.  The study treatments are to be 
given in addition to local SOC treatment with limited restrictions as described in 
Section 9.4.9.1.
9.4.1
Treatments Administered
The IP will only be administered to eligible patients by a medically qualified person as 
per the local 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 
the post-dose assessments described below. IP will be administered in a “slow bolus” 
injection to each study patient in an upper extremity vein within approximately 1 to 
2 minutes. 
During IP administration and until completion of post-administration 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 state and local regulations/SOC, to resuscitate a patient in the event of a medical 
emergency.  
At IP administration visits conducted on an outpatient basis after hospital discharge, the 
patient should not be released from the study center until the following are completed:

Postadministration vital sign measures (approximately 15 minutes after 
administration)


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 state (investigator or subinvestigator) determines that 
they are medically able to leave the study center and provides written sign-off not 
less than 15 minutes following administration (see IV Administration and

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 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 ICF at Screening (Visit 1), study personnel will register the 
patient in the IWRS, and the system will assign the patient a sequential PID. 
 
 
 
 
 
 
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 randomized patient at the time 
of randomization. Study centers will dispense IP according to the IWRS instructions. 
Study centers will also log on to the IWRS at subsequent visits to obtain a study 
medication 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 dose of rapastinel in this study was 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 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.

Selection and Timing of Dose for Each Patient
The IP will be administered IV using the assigned single-use prefilled syringes at 
Visits 2, 6, 8, and 9.
9.4.6.1
Screening Period
At Screening (Visit 1) after written consent is obtained, patients enter a screening period 
of up to 5 days. No IP is administered during the screening period.
9.4.6.2
Double-blind Treatment Period
Patients who meet all eligibility criteria at Screening (Visit 1) and who continue to meet 
all the eligibility criteria for participation in the study at the Baseline Visit (Visit 2) will 
be assigned an IP kit number via IWRS at Baseline (Visit 2). Patients will receive the 
first dose of IP that day. The IP kit numbers will also be assigned by IWRS at subsequent 
treatment visits (ie, Visits 6, 8, and 9).
Patients will receive either rapastinel 450 mg or placebo from a prefilled single-dose 
syringe at Visits 2, 6, 8, and 9. 
9.4.6.3
Safety Follow-up Period 
Patients who complete 4 weeks of randomized treatment and those who discontinue the 
study prematurely should enter the safety follow-up period. No IP is administered during 
the safety follow-up period and patients may be treated as deemed appropriate by the 
investigator.
9.4.7
Blinding
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.
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 identification of the IP for the medical management of the patient. The 
investigator must notify the Medical Safety Physician immediately (refer to Appendix II) 
and a full written explanation must be provided if the blind is broken. Before IP is 
unblinded, every attempt should be made to discuss the case with the study physician or 
Medical Safety 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.
For IWRS Unblinding
In an emergency, the investigator can obtain the treatment assignment of any patient at 
his or her study center through the IWRS. The investigator will access the IWRS to break 
the blind.
9.4.9
Prior and Concomitant Therapy
Medication history (psychotropic medication history during the previous 2 years and all 
other medications during the past 12 months) will be recorded at Screening (Visit 1) in 
the eCRF. Thereafter, any changes in concomitant medications or any new medications 
added will be recorded in the eCRF.

For women of childbearing potential and male partners of childbearing potential who 
may participate in the study, the following methods of contraception, if properly used, are 
generally considered reliable: hormonal contraceptives (ie, oral, patch, injection, 
implant), male condom with intravaginal spermicide, diaphragm or cervical cap with 
spermicide, vaginal contraceptive ring, intrauterine device, surgical sterilization (bilateral 
tubal ligation, bilateral salpingectomy), vasectomized partner, or sexual abstinence.
The investigator and each patient will determine the appropriate method of contraception 
for the patient during the participation in the study.
See Section 9.5.2.3 for pregnancy reporting procedures.

Efficacy Assessments
The efficacy assessments (MADRS and S-STS) will be administered by a psychiatrist, 
doctoral-level clinical psychologist, or other clinician who has extensive professional 
training and experience in the diagnosis of mental illness and who meets the training 
requirements and qualifications standards set by the sponsor and rater training vendor.
9.5.1.2.1
The Montgomery-Åsberg Depression Rating Scale
The MADRS (Montgomery and Åsberg, 1979) is a clinician-rated scale. The MADRS 
will be used to assess depressive symptomatology. Patients are rated on 10 items to 
assess feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep 
or appetite, difficulty concentrating, and lack of interest. Each item will be scored on a 
7-point scale. A score of 0 indicates the absence of symptoms, and a score of 6 indicates 
symptoms of maximum severity.
The MADRS will be evaluated at the timepoints indicated in Schedule of Evaluations 
(Section 2.0) using the Structured Interview Guide for the MADRS (SIGMA) 
methodology (Williams and Koback 2008).  At Screening (Visit 1) and Baseline (Visit 2) 
the MADRS will be administered with a look-back timeframe of 1 week.  At all other 
administrations, the MADRS will be administered with a look-back timeframe of “since 
last evaluation”.
9.5.1.2.2
Sheehan - Suicidality Tracking Scale 
The Sheehan - Suicidality Tracking Scale (S-STS) (Sheehan et al, 2014a; Sheehan et al, 
2014b) is a patient-report informed, clinician-rated scale used to rate the severity of both 
suicidal ideation and behavior.  The scale is compatible with the FDA categories for 
prospective assessment of suicidal ideation and behavior (FDA, 2012).  Developed for 
use as both a safety and efficacy outcome measure in research and in clinical settings, the 
scale is sensitive enough to detect an efficacy signal in conventional sample sizes used in 
clinical trials.  Each administration of the S-STS will include the patient- and clinician-
rated “Global Severity of Suicide Impulses, Thoughts, and Behaviors” items extracted 
from the Sheehan - Suicidality Tracking Scale: Clinically Meaningful Change Measures 
(S-STS CMCM) (Sheehan et al, 2014b).

administered with a look-back timeframe of 1 week.  At all other administrations, the 
S-STS will be administered with a look-back timeframe of “since last evaluation”.
9.5.1.2.3
Clinician’s Assessment of Readiness for Hospital Discharge  
The clinician’s assessment of readiness for hospital discharge will capture the date of 
readiness for discharge based solely on clinical factors associated with the patient’s initial 
hospitalization for acute suicidality, regardless of whether actual discharge occurred on 
that date. The assessment should reflect the date upon which the patient has clinically 
improved to the extent that they would be eligible for discharge without consideration of 
protocol requirements, social factors, or other reasons that may prevent the actual 
discharge from occurring on that date.  This assessment will be administered by a 
psychiatrist or other clinician who has extensive professional training and experience in 
the diagnosis of mental illness and is authorized to make decisions regarding 
hospitalization and discharge of patients.
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).

40
Naurex
RAP-MD-20 Protocol
26 Sep 2017
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.
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

41
Naurex
RAP-MD-20 Protocol
26 Sep 2017
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

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
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.
Any postbaseline worsening (as opposed to lack of improvement) of symptoms of 
suicidal ideation or behavior that is clinically significant based on the judgment of the 
investigator should be captured as an SAE.
Any extension of hospitalization beyond 14 days postbaseline for symptoms of suicidal 
ideation, behavior, or depression (eg, lack of improvement over 14 days), excluding other 
reasons such as placement issues, should be captured as an SAE.
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

43
Naurex
RAP-MD-20 Protocol


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.
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 and Events of 
Interest
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 the sponsor 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 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 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 fax it to the SAE/Pregnancy 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 (or in female partners of male patients 
occurring during the time frame described above) 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.

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. 
 
 will be captured using an electronic source 
tablet-based system, with paper source to be used only as a backup if it is not possible to 
use the tablet-based system. 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.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
9.7.1
Analysis Populations
Four populations will be considered in the statistical analysis of the study, as specified in 
the following subsections.
9.7.1.1
Screened Population
The Screened Population will consist of all patients who sign informed consent and 
receive a PID number.
9.7.1.2
Randomized Population
The Randomized Population will consist of all patients in the Screened Population who 
are randomized to a treatment group in the study.
9.7.1.3
Safety Population
The Safety Population will consist of all patients in the Randomized Population who took 
at least 1 dose of randomized IP.

61
Naurex
RAP-MD-20 Protocol
26 Sep 2017
9.7.1.4
Intent-to-Treat Population
The Intent-to-Treat (ITT) Population will consist of all patients in the Safety Population 
who had at least 1 postbaseline assessment of the MADRS total score. 
9.7.2
Patient Disposition
The number and percentage of patients in the Randomized, Safety, and ITT populations
will be summarized by treatment group and study center; the Screened Population will 
only be summarized overall and by study center.
Screen failures (ie, patients screened but not randomized) and the associated reasons for 
failure to randomize will be tabulated overall for the Screened Population. The number 
and percentage of patients who complete the DBTP, patients who prematurely 
discontinue during the same period and who enter the safety follow-up period will be 
presented for each treatment group and pooled across treatment groups for the 
Randomized Population. The reasons for premature discontinuation from the DBTP as 
recorded on the termination pages of the eCRFs will be summarized (number and 
percentage) by treatment group for the Randomized Population.
9.7.3
Demographics and Other Baseline Characteristics
Demographic parameters (eg, age, race, ethnicity, sex, weight, height, body mass index 
[BMI]) and other baseline characteristics will be summarized by treatment group for the 
Safety and ITT populations. 
9.7.4
Extent of Exposure and Treatment Compliance
9.7.4.1
Extent of Exposure
The number and percent of patients who received 1, 2, 3, and 4 randomized IV doses will 
be summarized by treatment group for the Safety Population.
Prior medication is defined as any medication taken before the date of the first dose of 
randomized IP. Concomitant medication is defined as any medication taken on or after 
the date of the first dose of randomized IP. 
Both prior and concomitant medication use will be summarized by the number and 
proportion of patients in each treatment group receiving each medication within 
each therapeutic class for the Safety Population. Multiple medication use by a patient will 
only be counted once.

62
Naurex
RAP-MD-20 Protocol
26 Sep 2017
9.7.4.2
Measurement of Treatment Compliance
Dosing compliance for a specified period is 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. Descriptive statistics for 
IP compliance will be presented by treatment group for each week, as well as for the 
whole DBTP of the study for the Safety Population.
9.7.5
Efficacy Analyses
All 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. 
For efficacy analyses in which study center is a factor, a small center will be defined as a 
center with < 2 patients in ≥ 1 treatment group in the ITT Population. Small centers will 
be pooled to form pseudo-centers so that each treatment group includes ≥ 2 ITT patients 
within the center. Pooling will be done using the following algorithm: 
Based on the number of ITT patients, small centers will be ordered from the largest to the 
smallest, and centers of the same size will be ordered from the largest center code to the 
smallest center code. The pooling process starts with the largest small center from the 
top, which will be pooled with the smallest from the bottom until a non-small center is 
formed. The process will be repeated using the small centers left out after the first pass. If 
any centers are left out at the end of the process, they will be pooled with the smallest 
pseudo-center. If there is > 1 smallest pseudo-center, the pseudo-center with the smallest 
center code will be selected. In case the pseudo-center formed by pooling all small 
centers is still a small center, it will be pooled with the smallest non-small center. If there 
is > 1 smallest non-small center, the one with the smallest center code will be selected.
9.7.5.1
Primary Efficacy Parameter
The primary efficacy parameter will be the change from baseline in MADRS total score 
at 1 day after first dose of treatment. The primary analysis will be performed using an 
analysis of covariance (ANCOVA) model with terms for treatment, study center, and 
baseline MADRS total score. The analysis will be performed based on postbaseline 
scores using only the observed cases without imputation of missing values. The treatment 
difference for rapastinel versus placebo will be estimated and reported along with the 
corresponding 95% CI and the p-value for superiority testing.

63
Naurex
RAP-MD-20 Protocol
26 Sep 2017
9.7.5.2
Key Secondary Efficacy Parameter
The key secondary efficacy parameter will be the change from baseline in S-STS total 
score at 1 day after first dose of treatment. The same statistical method for the primary 
efficacy parameter will be used for the key secondary efficacy parameter with baseline S-
STS total score as the covariant in the ANCOVA model.
To control the overall type I error rate for multiple comparisons of rapastinel with 
placebo for primary and key secondary endpoints, Hochberg testing procedure will be 
implemented.

Adverse Events
All AEs will be coded by system organ class and preferred term using the Medical 
Dictionary for Regulatory Activities.
An AE (classified by preferred term) will be considered a treatment-emergent adverse 
event (TEAE) if it was not present before the first dose of IP or was present before the 
date of the first dose of IP and increased in severity after the first dose of IP. If more than 
1 AE is reported before the first dose of IP and coded to the same preferred term, the AE 
with the greatest severity will be used 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 considered as a TEAE.
The number and percentage of patients reporting TEAEs in each treatment group will be 
tabulated by system organ class and preferred term and further categorized by severity 
and causal relationship to the IP. If more than 1 AE is coded to the same preferred term 
for the same patient, the patient will be counted only once for that preferred term using 
the greatest severity and strictest causality for the summarization by severity and causal 
relationship.

67
Naurex
RAP-MD-20 Protocol
26 Sep 2017
The distribution of TEAEs by severity and relationship to the IP will be summarized by 
treatment group. 
An AE that occurs more than 30 days after the date of the last dose of IP will not be 
summarized.
The incidence of common (≥ 2% of patients in any treatment group) TEAEs and AEs 
leading to premature discontinuation of IP will be summarized by preferred term and 
treatment group and sorted by decreasing frequency for the test treatment. 
An SAE that occurred between the date of the first dose of IP and 30 days after the date 
of the last dose of IP, inclusive, will be considered an on-therapy SAE. The number and 
percentage of patients who have on-therapy SAEs will be summarized by preferred term 
and treatment group. In addition, the incidence of on-therapy SAEs that led to death will 
be summarized separately by preferred term for each treatment group.
Listings will be presented for patients with SAEs, patients with AEs leading to 
discontinuation, and patients who die (if any). All patients with SAEs, including SAEs 
reported during the screening period and the safety follow-up period, and patients 
discontinuing because of AEs occurring before the start of IP will be included in these 
listings.

Determination of Sample Size
This study will randomize approximately 300 patients to the rapastinel 450 mg and 
placebo groups in a 1:1 ratio. The primary efficacy endpoint is the change from baseline 
in the MADRS total score at 1 day after the first dose of treatment. Assuming the SD is 
10 points, a sample size of 150 patients per treatment group will provide 90% power to 
detect a difference of 3.76 points for a rapastinel dose versus placebo at a 2-sided 
significance level of 5%.

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 timepoints 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).
All analyses that are required to support the DSMB will be performed by an independent
unblinded statistician 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.

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 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 timepoints, 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.
An important 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. Important protocol deviations must be reported to the sponsor within 
24 hours, if possible. The IRB must be notified within the time period dictated by the IRB 
associated with this study.

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.

APPENDICES
APPENDIX I.
ELEMENTS OF INFORMED CONSENT
Procedures will comply with 21 CFR, Parts 50 and 312. Signed informed consent will be 
obtained from 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, the 
sponsor, the IRB, 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 may be required.)

A statement that participation is voluntary, that refusal to participate will involve no 
penalty or loss of benefits to which the 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

Any additional costs to the patient that may result from participation in the research

The consequences of a patient’s decision to withdraw from the research and 
procedures for an orderly termination of the patient’s participation

A statement that significant new findings developed during the course of the research 
that may relate to the patient’s willingness to continue participation will be provided 
to the patient

The approximate number of patients involved in the study
