A Multicenter, Randomized, Double-Blind, Parallel-Group, Placebo-Controlled Study Evaluating the Efficacy, Safety, and Pharmacokinetics of SAGE-217 in the Treatment of Adult Female Subjects With Severe Postpartum Depression

The primary purpose of this study was to determine if treatment with SAGE-217 reduces depressive symptoms in participants with severe postpartum depression (PPD) compared to placebo as assessed by the change from baseline in the 17-item Hamilton Rating Scale for Depression (HAM-D) total score at Day 15 and to evaluate the safety and tolerability of SAGE-217 compared to placebo as assessed by the incidence of adverse events, vital sign measurements, clinical laboratory evaluations, electrocardiogram (ECG) parameters, and the Columbia Suicide Severity Rating Scale (C-SSRS).
