Abstract
Abstract Objective: To compare hospitalization rates in patients with schizophrenia treated prospectively with aripiprazole once-monthly 400 mg (AOM 400; an extended-release injectable suspension) vs the same patients' retrospective rates with their prior oral anti-psychotic therapy. Research design and methods: Multi-center, open-label, mirror-image, naturalistic study in a community setting in North America. Patients who required a change in treatment and/or would benefit from long-acting injectable anti-psychotic therapy were treated prospectively for 6 months with AOM 400. Retrospective data on hospitalization rates were obtained. Clinical trial registration: ClinicalTrials.gov: NCT01432444. Main outcome measures: The proportion of patients with >/=1 psychiatric inpatient hospitalization with oral anti-psychotic therapy examined retrospectively (months -4 to -1 before oral conversion) and after switching to AOM 400 (months 4-6 after initiating AOM 400). Results: Psychiatric hospitalization rates were significantly lower when patients were treated with AOM 400 compared with oral anti-psychotic therapy both in the 3-month primary efficacy sample (2.7% [n = 9/336] vs 27.1% [n = 91/336], respectively; p < 0.0001) and in the total sample (6-month prospective rate: 8.8% [n = 38/433] vs 6-month retrospective rate: 38.1% [n = 165/433]; p < 0.0001). Discontinuations due to adverse events (AEs) during cross-titration were lower in patients cross-titrated on oral aripiprazole for >1 and(2.9% [n = 7/239]) compared with patients cross-titrated for
