- Primary Outcome Measures
Name Time Method Change From Baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) Score at Week 6 Baseline (Week 0) to Week 6 The Montgomery-Åsberg Depression Rating Scale (MADRS) is a 10-item, clinician-rated scale that evaluates the participant's depressive symptomatology during the past week. Participants were rated on items assessing feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty in concentration, and lack of interest. Each of the 10 items was scored on a 7-point scale with a score of 0 reflecting no symptoms and a score of 6 reflecting symptoms of maximum severity for a total possible score of 0 (best) to 60 (worst). A negative change from Baseline indicates improvement.
- Secondary Outcome Measures
Name Time Method Change From Baseline in Clinical Global Impressions-Severity (CGI-S) Score at Week 6 Baseline (Week 0) to Week 6 The Clinical Global Impressions-Severity (CGI-S) is a clinician-rated scale that measures the overall severity of a participant's illness in comparison with the severity of other participants the physician has observed. The participant was rated on a scale from 1 to 7, with 1 indicating a "normal state" and 7 indicating "among the most extremely ill participants." A negative change from Baseline indicates improvement.
