PRIMARY outcome

Timeframe: 6 weeks

Population: Intent-to-Treat (ITT) Set contains all randomized patients who received at least one dose of study medication and who had a valid baseline (pre-dose) measurement and at least one valid post-baseline measurement of MADRS total score.

The Montgomery-Åsberg Depression Rating Scale (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.
