What this trial is about
This is a prospective, 12-week, randomized, double-blind, placebo-controlled study, designed to evaluate the efficacy, safety, and tolerability of a dose of evenamide of 15 mg bid, compared to placebo, as add-on treatment in patients with documented treatment-resistant schizophrenia (TRS) who have prospectively demonstrated inadequate response to their current stable therapeutic dose of an antipsychotic(s). Approximately 400 patients will be randomized equally (1:1) to each of the two treatment groups in this study.
