What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from Baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score at the End of the Double Blind Treatment Period (DBTP) (end of Week 6)	The MADRS, a clinician-rated scale, will be used to assess depressive symptomatology. Participants are rated on 10 items to assess feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty concentrating, and lack of interest. Each item will be scored on a 7-point scale. A score of 0 indicates the absence of symptoms, and a score of 6 indicates symptoms of maximum severity.	Baseline to end of Week 6

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from Baseline in MADRS Total Score at Day 1 Post-first Dose of Treatment	The MADRS, a clinician-rated scale, will be used to assess depressive symptomatology. Participants are rated on 10 items to assess feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty concentrating, and lack of interest. Each item will be scored on a 7-point scale. A score of 0 indicates the absence of symptoms, and a score of 6 indicates symptoms of maximum severity.	Baseline to Day 1 post-first dose
