Study Endpoints

Primary Endpoints

Severity and frequency of treatment-emergent adverse events, serious adverse events, adverse events of special interest, and events of clinical interest
From the start of treatment in the open-label extension study through 8 weeks after the last dose
Change from baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score at Week 6.
Baseline to Week 6
Change from baseline in the Hamilton Depression Rating Scale, 17-item (HAMD-17) score at Week 6
Baseline to Week 6

The HAMD-17 consists of 17 items that are used to rate the severity of depression symptoms. Each item is scored in a range of 0 to 2 points or 0 to 4 points, with higher scores indicating a greater degree of depression. The score for each item is summed to compute a total score, which ranges from 0 to 52 points.

Secondary Endpoints

Change from baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score over time
From baseline through the active extension treatment (Week 52)
Change in Clinical Global Impression of Severity (CGI-S) score over time
From baseline through the active extension treatment (Week 52)
Change from baseline in the Snaith-Hamilton Pleasure Scale (SHAPS) total score over time
From baseline through the active extension treatment (Week 52)
