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

Eligibility Criteria
You may qualify if:
- 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
- Patients with a total score of ≥18 on the 17-item Hamilton Rating Scale for Depression (HAM-D)
You may not qualify if:
- Patients with a diagnosis of any of the following diseases according to DSM-5 Neurocognitive disorders, history or complication of schizophrenia spectrum or other psychotic disorder, history or complication of bipolar and related disorders, feeding and eating disorders, obsessive-compulsive disorder, panic disorder, posttraumatic stress disorder, personality disorders, neurodevelopmental disorders, substance-related and addictive disorders (within 180 days prior to informed consent)
- Patients exhibiting mood-incongruent psychotic features in the current major depressive episode
- Patients who, in the opinion of the investigator or subinvestigator, are judged to have treatment-resistant depression, ie, a certain degree of therapeutic effect is not obtained by administration of 2 or more antidepressants having different mechanisms of action at sufficient doses for at least 6 weeks for the current major depressive episode
- Patients receiving augmentation treatment, such as antipsychotics, for the current major depressive episode (excluding the use of sulpiride for depression/depressive state or gastric/duodenal ulcer)
