Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score | Baseline and 1 Day | The MADRS is a clinician-rated scale to assess depressive symptomatology during the preceding week. Participants are rated on 10 items (feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty concentrating, and a lack of interest) each on a 7-point scale from 0 (no symptoms) to 6 (symptoms of maximum severity). The total score ranges from 0 to 60 with a higher score indicating more depression. A negative change score indicates improvement. |
| Change From Baseline in Sheehan - Suicidality Tracking Scale (S-STS) Total Score | Baseline and 1 Day | The S-STS is a patient-report informed, clinician-rated scale used to rate the severity of suicidal impulses, thoughts, and behaviors. This is a 14 item scale ranging from 0=Not at all to 4= Extremely. The total score ranges from 0 to 56 with a higher score indicating higher suicidal tendency. |

Outcome results
Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score
The MADRS is a clinician-rated scale to assess depressive symptomatology during the preceding week. Participants are rated on 10 items (feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty concentrating, and a lack of interest) each on a 7-point scale from 0 (no symptoms) to 6 (symptoms of maximum severity). The total score ranges from 0 to 60 with a higher score indicating more depression. A negative change score indicates improvement.
Time frame: Baseline and 1 Day
Population: The modified Intent-to-Treat (mITT) Population consists of all participants in the Safety Population who had at least 1 postbaseline assessment of the MADRS total score or S-STS total score.
