Outcomes
Primary Outcomes
Change From Baseline in HAM-D17 Total Score at the Final On-therapy (FOT)Evaluation (Week 8 or ET)
Time Frame: Baseline and Week 8 (or ET)
HAM-D17: a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on either a 3 point (0 to 2) or a 5 point scale (0 to 4), with 0=none/absent and 4=most severe, for a maximum total score of 50.
Secondary Outcomes
- Number of Participants With Categorical Scores on CGI-Improvement (CGI-I) at FOT Evaluation (Week 8 or ET)(Week 8 (or ET))
- Change From Baseline in Mean CGI-S Score at FOT Evaluation (Week 8 or ET)(Baseline and Week 8 (or ET))
- Change From Baseline in MADRS Total Score at FOT Evaluation (Week 8 or ET)(Baseline and Week 8 (or ET))
- Change From Baseline in HAM-D6 Total Score at FOT Evaluation (Week 8 or ET)(Baseline and Week 8 (or ET))
- Number of Participants With a Response on the HAM-D17 at FOT Evaluation (Week 8 or ET)(Week 8 (or ET))
- Number of Participants in Remission Based on the HAM-D17 at FOT Evaluation (Week 8 or ET)(Week 8 (or ET))
- Number of Participants With a Response on the MADRS Score at FOT Evaluation (Week 8 or ET)(Week 8 (or ET))
- Number of Participants With a Response on the CGI-I Score at FOT Evaluation (Week 8 or ET)(Week 8 (or ET))
