A Randomized, Double-Blind, Placebo-Controlled, Sequential Parallel Study of CERC-301 in the Adjunctive Treatment of Subjects With Severe Depression and Recent Active Suicidal Ideation Despite Antidepressant Treatment

The current study will evaluate the antidepressant effect of CERC-301 during 28 days of treatment in subjects with MDD who are currently experiencing a severe depressive episode despite stable ongoing treatment with selective serotonin- or serotonin-norepinephrine reuptake inhibitors (SSRI or SNRI). The study population will be enriched for subjects that would benefit most from rapid onset, those with recent active suicidal ideation, but not a risk to themselves or others and are deemed appropriate for an out-patient study with careful safety surveillance. This will allow the study to focus on the antidepressant effects of CERC-301 but also explore effects on suicidal ideation. To explore rapid onset, the primary endpoint will be at 7 days, but effects over the 28 days of treatment will be examined as a secondary endpoint.

   2. Women of childbearing potential (WOCBP) meeting the criteria below:

   i. Uses an acceptable double-barrier method of contraception as determined by the Investigator -and- ii. Is not lactating, has a negative serum beta human chorionic gonadotropin pregnancy test at screening and a negative urine pregnancy test prior to randomization on Day 0.

3. Male subjects must agree to use a condom if partner is of childbearing potential.
4. Diagnosis of MDD recurrent without psychotic features according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria with diagnosis confirmed using the Structured Clinical Interview for DSM-IV Axis I Disorders Clinical Trials Version (SCID-CT).
5. Currently adhering to antidepressant drug regimen that consists of stable SSRI or SNRI therapy
6. Inadequate antidepressant response to current antidepressant therapy despite adequate dose and duration
7. HDRS-17 score ≥ 21 on the HDRS-17 performed by the site at screening
8. Recent active suicidal ideation defined as a score of 2 on the intensity of ideation section on the Columbia-Suicide Severity Rating Scale (C-SSRS) during the four weeks prior to screening using the "Baseline/Screening" version of the C-SSRS.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
HDRS-17 after 7 days of dosing with study drug	The overall between-treatment difference will be computed as the weighted average of the differences (drug vs. placebo)	Screening & Days 0, 4, 7, 11, 14, 21,28, & 35

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
HDRS-17 Averaged between 7 and 28 days of treatment with study drug	This will be analyzed using the mixed effects model for repeated measures. The between-group (drug vs. placebo) differences will be estimated by the least squares mean for the contrast in the main effect.	Screening, Days 0, 4, 7, 11, 14, 21, 28, & 35
HDRS-17 after 28 days of dosing with study drug	This will be analyzed using the mixed effects model for repeated measures . The between-group difference will be estimates by the least squares mean difference at Day 28 as a simple contrast from the model.	Screening, Days 0, 4, 7, 11, 14, 21, 28, 35
