Outcome Measures

Primary Outcomes (1)

  • Mean Change From Baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score at Week 6 of the Double-blind Treatment Period

    The MADRS was a clinician-rated scale which evaluated the level of depression. The MADRS consists of following 10 depressive symptoms on 7 scales of 0 to 6, with higher scores indicating worse condition. 1\. Apparent sadness, 2. Reported sadness, 3. Inner tension, 4. Reduced sleep, 5. Reduced appetite, 6. Concentration difficulties, 7. Lassitude, 8. Inability to feel, 9. Pessimistic thoughts, and 10. Suicidal thoughts Summed subscales were combined to compute a total score. Total score ranges form 0 to 60, with higher scores indicating worse condition.

    Baseline, Week 1, 2, 3, 4, 5, and 6

Secondary Outcomes (2)

  • MADRS Response Rate

    Baseline, Week 1, 2, 3, 4, 5, and 6
