Study Summary

This is a randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of 10, 20, 40 and 60 mg oral PRAX-114 compared to placebo in the treatment of adults with MDD. The study will enroll participants on adjunctive treatment who had an inadequate response to their current antidepressant treatment and participants not currently being treated with pharmacotherapy for MDD. A sub-study to investigate the pharmacokinetics (PK) of PRAX-114 and metabolites when dosed in the evening in participants with MDD will be conducted in a subset of participants at selected research sites with serial PK sampling capabilities.

Primary Outcome

The HAM-D17 is a depression rating scale consisting of 17 items; 9 items are scored on a 5-point scale (ranging from 0 to 4), and 8 items are scored on a 3-point scale (ranging from 0 to 2). The total score of the 17 items ranges from 0 to 52 with higher scores indicating greater depression. Therefore, a decrease in the total score or on individual item scores indicates improvement.
