PRIMARY outcome

Timeframe: Baseline to Week 9

Population: All randomized patients who took at least one dose of study medication and had at least one post baseline assessment, with last observation carried forward to week 9 for patients who did not complete the study.

MADRS total score (0-60 units), where lower scores indicate less depressive symptoms, calculated as Week 9 value - baseline value.

SECONDARY outcome

Timeframe: Baseline to Week 9

Population: All randomized patients who took at least one dose of study medication and had at least one post baseline assessment, with last observation carried forward to week 9 for patients who did not complete the study. Patients not on medication at baseline would have left the item blank and therefore no change from baseline could be calculated
