Outcome Measures
Primary Outcomes (1)
Change in the Montgomery-Asberg Depression
To assess the change in the Montgomery-Asberg Depression Rating Scale (MADRS) Total Score from Baseline (End of Phase A \[Week 8\]) to Week 14. The MADRS was utilized as the primary efficacy assessment of the participant's level of depression and was administered utilizing the Structured Interview Guide for the MADRS (SIGMA). The MADRS consisted of 10 items each with 7 defined grades of severity. The rater decided whether the rating lied on predefined scale steps (0, 2, 4, 6) or between them (1, 3, 5). The 10 items were apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, suicidal thoughts. Each item was scored using a scale of 0 to 6 (a higher score indicates increased severity). The maximum total score was 60; 0, no symptom; 60, severely affected.
From baseline (end of Phase A [Week 8]) to week 14
Secondary Outcomes (3)
Change in the Sheehan Disability Scale (SDS) From Baseline to End of Treatment
From baseline (end of Phase A [Week 8]) to week 14
Change From End of Phase A to End of Phase B in MADRS Total Score for the Subpopulation With <25% Improvement From Baseline of Phase A to End of Phase A in MADRS Total Score
From baseline (end of Phase A [Week 8]) to week 14
Change From End of Phase A to End of Phase B in MADRS Total Score for the Subpopulations With Anxious Distress as Specified in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V).
From baseline (end of Phase A [Week 8]) to week 14
