摘要:
The present study aimed to evaluate the efficacy and safety of aripiprazole once-monthly (AOM) compared to oral aripiprazole in treating acute schizophrenia.This randomized, double-blind, non-inferiority study recruited patients from 15 trial sites across China from May 2017 to April 2019. Patients with an acute psychotic episode received AOM at 400 mg or oral aripiprazole at 10-20 mg for 12 weeks. The primary and secondary efficacy endpoints were the difference in scores from baseline to week 10, as assessed on the Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impressions-Severity (CGI-S) scores, respectively.A total of 436 patients were randomized. Among them, 159/218 (72.9%) and 165/218 (75.7%) in the AOM and oral aripiprazole groups completed 10 weeks of treatment, respectively. The least-squares (LS) mean changes from baseline to endpoint (week 10) in PANSS were - 33.6 for the AOM group and - 34.8 in the oral aripiprazole group, respectively, with a difference of - 1.2 (95% CI: - 4.1, 1.7). The non-inferiority margin of AOM to oral aripiprazole was - 4.1, which was above the lower limit of the pre-defined margin. The altered CGI-S score was - 2.2 and - 2.3 in the AOM and oral aripiprazole groups, respectively. The incidence of treatment-emergent adverse events (TEAEs) was similar in both groups. The rate of discontinuation due to TEAEs was 2.3% and 3.2% in the AOM and oral aripiprazole groups, respectively.This study confirmed the efficacy and safety of AOM for the treatment of Chinese patients with acute schizophrenia. The non-inferiority of AOM to oral aripiprazole was established, with comparable efficacy and tolerability. These findings suggested that AOM could be used as a treatment option for patients experiencing an acute episode of schizophrenia.ClinicalTrials.gov identifier: NCT03172871.© 2022.
