- Change in Montgomery Asberg Depression Rating Scale (MADRS)-6 Score Using Average of Changes From Baseline to Week 3 Through the End of Treatment Period (Week 5 for Stage 1, Week 6 for Stage 2) [ Time Frame: Baseline and 5 weeks (Stage 1) and baseline and 6 weeks (Stage 2), combined together for the overall estimate of treatment effect ]The MADRS-6 scale is a clinician-administered questionnaire used to measure the severity of MDD symptoms. The MADRS-6 scale is a subset of the MADRS-10 scale, comprised of the following individual questionnaire items: Apparent Sadness, Reported Sadness, Inner Tension, Lassitude, Inability to Feel, and Pessimistic Thoughts. Scores range from 0 (no apparent symptoms) to 36 (most severe symptoms).
- Change in MADRS-10 Score Using Average of Changes From Baseline to Week 3 Through the End of Treatment Period (Week 5 for Stage 1, Week 6 for Stage 2) [ Time Frame: 5-6 Weeks (5 weeks for Stage 1 and 6 weeks for Stage 2) ]The MADRS-10 scale is a clinician-administered questionnaire comprised of 10 items used to measure the severity of MDD symptoms. Scores range from 0 (no apparent symptoms) to 60 (most severe symptoms). Individual questionnaire items include: Apparent Sadness, Reported Sadness, Inner Tension, Reduced Sleep, Reduced Appetite, Concentration Difficulties, Lassitude, Inability to Feel, Pessimistic Thoughts, and Suicidal Thoughts.
- Change From Baseline to End of Treatment in the MADRS-10 [ Time Frame: 5-6 Weeks (5 weeks for Stage 1 and 6 weeks for Stage 2) ]The MADRS-10 scale is a clinician-administered questionnaire comprised of 10 items used to measure the severity of MDD symptoms. Scores range from 0 (no apparent symptoms) to 60 (most severe symptoms). Individual questionnaire items include: Apparent Sadness, Reported Sadness, Inner Tension, Reduced Sleep, Reduced Appetite, Concentration Difficulties, Lassitude, Inability to Feel, Pessimistic Thoughts, and Suicidal Thoughts.
- Proportion of Patients Who Exhibited Treatment Response (MADRS-10) [ Time Frame: 5-6 Weeks (5 weeks for Stage 1 and 6 weeks for Stage 2) ]The proportion of subjects demonstrating MADRS-10 treatment response, defined as a ≥ 50% reduction in MADRS-10 score from baseline to the end of the efficacy period (week 5). The MADRS-10 scale is a clinician-administered questionnaire comprised of 10 items used to measure the severity of MDD symptoms. Scores range from 0 (no apparent symptoms) to 60 (most severe symptoms). Individual questionnaire items include: Apparent Sadness, Reported Sadness, Inner Tension, Reduced Sleep, Reduced Appetite, Concentration Difficulties, Lassitude, Inability to Feel, Pessimistic Thoughts, and Suicidal Thoughts.
- Remission Rate [ Time Frame: 5-6 Weeks (5 weeks for Stage 1 and 6 weeks for Stage 2) ]The proportion of subjects achieving remission, defined as a MADRS-10 score of ≤10 at the end of the efficacy period.
- Number of Subjects With Adverse Events (AEs) [ Time Frame: 5-6 Weeks (5 weeks for Stage 1 and 6 weeks for Stage 2) ]
