About
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.

Exclusion criteria
-
History of substance abuse or dependence within the 3 months prior to screening.
-
Positive urine drug test at screening and prior to randomization on Day 0 unless due to a permitted medication that is documented in the subject's medication history.

-
Elevated semi-recumbent blood pressure at screening and prior to randomization on Day 0, defined as systolic blood pressure > 140 mm Hg and diastolic blood pressure
-
Active, comorbid disease that might limit the ability of the subject to participate in the study as determined by the Investigator (i.e. poorly controlled diabetes mellitus, unstable angina, coronary artery disease, congestive heart failure, etc.).
-
Subjects with clinical laboratory test abnormality deemed clinically significant by the Investigator at screening.

-
Female subjects currently experiencing postpartum depression.
-
Subjects who, in the opinion of the Investigator, are not appropriate for a 35-day placebo-controlled study due to risk of significant threat to self or others during screening or study conduct.
-

-
Subjects with a C-SSRS score > 2 on the intensity of ideation section at randomization (Visit 2a), using the "Since Last Visit" version of the C-SSRS.
