Study to Determine the Safety, Tolerability, and Efficacy of Evenamide in Patients With Chronic Schizophrenia

This 4-week study will evaluate the safety, tolerability and preliminary evidence of efficacy of evenamide (7.5,and 15 mg and placebo, bid) treatment in outpatients with chronic schizophrenia.

This is a prospective, 4-week, randomized, double-blind, placebo-controlled, study designed to evaluate the safety, tolerability, EEG effects, and preliminary efficacy of two fixed oral doses of evenamide of 7.5 mg and 15 mg bid (15 and 30 mg/day) in outpatients with chronic schizophrenia who are receiving treatment at constant doses of one of the following atypical antipsychotics: aripiprazole, clozapine, quetiapine, olanzapine, paliperidone or risperidone. Approximately 120 patients will be randomized in a 1:1:1 ratio to receive either evenamide 7.5 or 15 mg, or placebo, given bid.
