    Abstract:
    OBJECTIVE: The study was designed to evaluate the short-term efficacy and safety of lurasidone in the treatment of acute schizophrenia. METHOD: Participants, who were recently admitted inpatients with schizophrenia with an acute exacerbation of psychotic symptoms, were randomly assigned to 6 weeks of double-blind treatment with 40 mg of lurasidone, 120 mg of lurasidone, 15 mg of olanzapine (included to test for assay sensitivity), or placebo, dosed once daily. Efficacy was evaluated using a mixed-model repeated-measures analysis of the change from baseline to week 6 in Positive and Negative Syndrome Scale (PANSS) total score (as the primary efficacy measure) and Clinical Global Impressions severity (CGI-S) score (as the key secondary efficacy measure). RESULTS: Treatment with both doses of lurasidone or with olanzapine was associated with significantly greater improvement at week 6 on PANSS total score, PANSS positive and negative subscale scores, and CGI-S score compared with placebo. There was no statistically significant difference in mean PANSS total or CGI-S change scores for the lurasidone groups compared with the olanzapine group. With responders defined as those with an improvement of at least 20% on the PANSS, endpoint responder rates were significant compared with placebo for olanzapine only. The incidence of akathisia was higher with 120 mg of lurasidone (22.9%) than with 40 mg of lurasidone (11.8%), olanzapine (7.4%), or placebo (0.9%). The proportion of patients experiencing ≥ 7% weight gain was 5.9% for the lurasidone groups combined, 34.4% for the olanzapine group, and 7.0% for the placebo group. CONCLUSIONS: Lurasidone was an effective treatment for patients with acute schizophrenia. Safety assessments indicated a higher frequency of adverse events associated with 120 mg/day of lurasidone compared with 40 mg/day.
