Brief summary

Change from Baseline (Day -1) to Day 42 in MADRS total score.

Detailed description

Change from Baseline (Day -1) to Day 84 in MADRS total score., Proportion of participants with response defined as a ≥50% decrease in MADRS total score from Baseline (Day -1) to Day 84. Response will also be assessed after each dosing session (Day 2 and Day 23) and through Day 84., Proportion of participants in remission defined as MADRS total score ≤10 at Day 84. Remission will also be assessed after each dosing session (Day 2 and Day 23) and through Day 84., Proportion of responders with a sustained response (sustained defined as those meeting response criteria on or before Day 42 and sustained through Day 84 with one score greater than that for the response criterion permitted)., Proportion of participants with a sustained remission (sustained defined as those meeting remission criteria on or before Day 42 and sustained through Day 84 with one score greater than that for the remission criterion permitted)., Change from Baseline to each timepoint assessed in BDI-II., Change from Baseline to each timepoint assessed in CGI-S score., CGI-I score at each timepoint to assess change since Baseline (Day -1)., Change from Baseline to each timepoint assessed in GAD-7 total score., Change from Baseline to each timepoint assessed in Q-LES-Q-SF total score.
