---|---|---|---|---|
Primary | Change From Baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score | The MADRS is a depression rating scale consisting of 10 items, each rated 0 (normal) to 6 (most abnormal). The 10 items represent the core symptoms of depressive illness. The overall score ranges from 0 (symptoms absent) to 60 (severe depression). A decrease in the total score or on individual items indicates improvement. Least squares (LS) means were from an Analysis of Covariance (ANCOVA) model with treatment as a fixed factor and the Baseline value as a covariate. | Baseline and Week 8 | No |
Secondary | Percentage of Participants With a MADRS Response at Week 8 | Response is defined as a participant with a =50% decrease in Montgomery Åsberg Depression Rating Scale (MADRS) total score from Baseline. The MADRS is a depression rating scale consisting of 10 items, each rated 0 to 6. The 10 items represent the core symptoms of depressive illness. The overall score ranges from 0 (symptoms absent) to 60 (severe depression). Decrease in the total score or on individual items indicates improvement. | Baseline and Week 8 | No |
Secondary | Percentage of Participants in MADRS Remission at Week 8 | Remission is defined as a participant with a Montgomery Åsberg Depression Rating Scale (MADRS) total score =10. The MADRS is a depression rating scale consisting of 10 items, each rated 0 to 6. The 10 items represent the core symptoms of depressive illness. The overall score ranges from 0 (symptoms absent) to 60 (severe depression). Decrease in the total score or on individual items indicates improvement. | Week 8 | No |
Secondary | Mean Clinical Global Impression Scale - Improvement (CGI-I) Score at Week 8 | The Clinical Global Impression - Global Improvement scale assesses the participant's improvement (or worsening) as assessed by the clinician relative to Baseline on a 7-point scale: 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse. LS means were from an ANCOVA model with treatment as a fixed factor and the Baseline Clinical Global Impression-Severity of Illness (CGI-S) score as a covariate. | Week 8 | No |
Secondary | Change From Baseline in Sheehan Disability Scale (SDS) Total Score at Week 8 | The Sheehan Disability Scale assesses functional impairment in 3 domains: work/school, social life or leisure activities, and family life or home responsibilities. The participant rates the extent to which each aspect is impaired on a 10-point visual analog scale, from 0 (not at all) to 10 (extremely). The 3 scores are added together to calculate the total score, which ranges from 0 to 30, with higher scores indicating more impairment. LS means were from an ANCOVA model with treatment as a fixed factor and the Baseline value as a covariate. | Baseline and Week 8 | No |
