Outcome Measures
Primary Outcomes (1)
Change From Baseline to Week 8 in the MADRS (Montgomery-Asberg Depression Rating Scale) Total Score.
The MADRS is an observer rating scale that has proven to be an efficient and practical measure of depression. The scale was constructed to be sensitive to treatment effects. The change from baseline in MADRS total score has a possible range of -60 to 60 where negative values reflect improvement in depression symptom severity. The method of last observation carried forward was utilized for subjects who discontinued prematurely.
Baseline, Week 1, Week 2, Week 4, Week 6, Week 8
Secondary Outcomes (5)
Change From Baseline to Week 8 in the HAM-D 17 (17-Item Hamilton Rating Scale for Depression) Total Score
Baseline, week 1, week 2, week 4, week 6, week 8
The CGI-I (Clinician's Global Impression of Improvement) Score at Week 8
Week 1, Week 2, Week 4, Week 6, Week 8
Change From Baseline to Week 8 in the HAM-A ( Hamilton Anxiety Rating Scale) Total Score
