Detailed Description
This is a Phase 2b, randomized, double-blind, placebo-controlled, parallel-group, multicenter trial to evaluate the efficacy and safety of Ropanicant versus placebo in patients with MDD. The study will be conducted at multiple centers located in the US. This study consists of a 4-weeks screening period, 6-weeks treatment period, and a 2-weeks follow-up period. Approximately 195 patients will be randomly assigned to receive Ropanicant either 30 mg bid or 45 mg bid, or placebo bid for 6 weeks in a ratio of 1:1:1 (65 patients in each treatment group).
