Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in Total MADRS Score From the Baseline to Week 8 Visit During the Treatment Period | 8 weeks | Montgomery-Asberg Depression Rating Scale (MADRS) Total Score: Scale ranges from 0 to 60 with a higher score indicating worsening symptoms of depression. Estimates were based on a Mixed-effects Model for Repeated Measures (MMRM) model with the treatment group, assessment timepoint, and the interaction between the treatment group and assessment timepoint as a factor and total MADRS score at baseline as a covariate. |
| Number of Participants With Adverse Events (AEs) | 10 weeks | An adverse event is any undesirable or unintended sign (including abnormal findings in general laboratory tests, body weight, and standard 12-lead ECG), symptom, or disease in a subject given the investigational drug, irrespective of the causal relationship to the investigational drug. |

Outcome results
Changes in Total MADRS Score From the Baseline to Week 8 Visit During the Treatment Period
Montgomery-Asberg Depression Rating Scale (MADRS) Total Score: Scale ranges from 0 to 60 with a higher score indicating worsening symptoms of depression. Estimates were based on a Mixed-effects Model for Repeated Measures (MMRM) model with the treatment group, assessment timepoint, and the interaction between the treatment group and assessment timepoint as a factor and total MADRS score at baseline as a covariate.
Time frame: 8 weeks
Population: Of subjects registered for randomization, those meeting all the following items were included in the full analysis set (FAS).~1. Subjects who received the investigational drug at least once during the treatment period.~2. Subjects who were evaluated for the total MADRS score at the baseline and at least one timepoint after the start of the treatment period.
| Arm | Measure | Value (LEAST_SQUARES_MEAN) | Dispersion |
|---|---|---|---|
| Placebo | Changes in Total MADRS Score From the Baseline to Week 8 Visit During the Treatment Period | -10.4 Score on a scale | Standard Error 0.7 |
| MD-120 50 mg | Changes in Total MADRS Score From the Baseline to Week 8 Visit During the Treatment Period | -11.1 Score on a scale | Standard Error 0.7 |
| MD-120 100 mg | Changes in Total MADRS Score From the Baseline to Week 8 Visit During the Treatment Period | -11.9 Score on a scale | Standard Error 0.7 |
Number of Participants With Adverse Events (AEs)
An adverse event is any undesirable or unintended sign (including abnormal findings in general laboratory tests, body weight, and standard 12-lead ECG), symptom, or disease in a subject given the investigational drug, irrespective of the causal relationship to the investigational drug.
Time frame: 10 weeks
Population: Of subjects registered for randomization, those meeting all the following items will be included in the safety analysis set in treatment period.~1. Subjects who have received the investigational drug at least once during the treatment period.~2. Subjects in whom the safety evaluation data after the dose of the investigational drug in the treatment period are available.
