Brief summary

Decrease from Baseline to Day 28 of the MADRS10 total score in REL-1017 compared to placebo in participants with inadequate response to ongoing ADT

Detailed description

Decrease from Baseline to Day 7 of the MADRS10 total score, MADRS10 response rate (improvement ≥50% compared with total Baseline score) at Day 28, MADRS10 remission rate (total score ≤10) at Day 28, Decrease from Baseline to Day 28 of the CGI-S score, Effect of the following covariates on primary endpoint: MADRS10 total score as a function of severity at baseline (MADRS baseline >35) tachyphylaxis/tolerance (yes/no), TRD (yes/no), time since first diagnosis of MDD, sex and age., CGI-I score at Day 7 and Day 28, Decrease from Baseline to Day 28 in MADRS10 component scores, Change from Baseline in DSST, Change from Baseline in ASEX, Change from Baseline to Day 28 of each Sheehan Disability Scale (SDS) domain score, Change from Screening to Day 28 of the Hamilton Anxiety Depression Scale (HAM-A) total score, Change from Baseline to Day 28 of potential blood markers of MDD or treatment outcome, Treatment-emergent adverse events (TEAEs), • Vital signs and weight • Physical examination • Clinical laboratory parameters (chemistry, hematology, and urinalysis), C-SSRS (Columbia Suicide Severity Rating Scale) Change from baseline at each assessment point. Safety end point and used to identify behaviors that may be indicative of an individual's intent to commit suicide and to guide adoption of appropriate measures, Evaluate the effects on QT interval with Fridericia's correction (QTcF) at Day 28, PK evaluation at Day 28
