PRIMARY outcome

Timeframe: Day 43

Population: The analysis of the primary and secondary efficacy outcome measures are based on the Modified Intent-to-Treat (mITT) Population which included 481 randomized patients. The mITT Population includes all randomized patients who received at least 1 dose of study drug, had a baseline MADRS total score, and who had at least one on-study drug, postbaseline MADRS total score.

Change from baseline to Day 43 in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score. The MADRS is a clinician-rated 10 item scale to assess depressive symptoms. Each item is rated on a 7-point scale from 0-6. The total score ranges from 0 to 60 with a higher score indicating increased severity of depressive symptoms.

SECONDARY outcome

Timeframe: Day 43

Change from baseline to Day 43 in the Clinical Global Impression Scale-Severity (CGI-S). The CGI-S is a clinician-rated scale to assess a patient's overall mental health. The scale ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill patients).
