Overview
Brief Summary
The objective of the trial is to compare the efficacy of OPC-64005 at 20 mg vs placebo and to assess the safety and pharmacokinetics of OPC-64005 at 10 and 20 mg in patients with major depressive disorder (MDD).The primary endpoint is the mean change from baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) total score at Week 6 of the double-blind treatment period in the OPC-64005 20-mg group compared with the placebo group
Investigators
Eligibility Criteria
Inclusion Criteria
- •Patients with a DSM-5 classification-based diagnosis of "major depressive disorder, single episode" or "major depressive disorder, recurrent episode" with the current episode persisting for ≥4 weeks to ≤1 year

Outcomes
Primary Outcomes
Mean Change From Baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score at Week 6 of the Double-blind Treatment Period
Time Frame: Baseline, Week 1, 2, 3, 4, 5, and 6
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.
Secondary Outcomes
- MADRS Response Rate(Baseline, Week 1, 2, 3, 4, 5, and 6)
- MADRS Remission Rate(Week6)
