Randomized Controlled Trial Multicenter Study Comparative StudyEfficacy of iloperidone in the short-term treatment of schizophrenia: a post hoc analysis of pooled patient data from four phase III, placebo- and active-controlled trials.
The efficacy and tolerability characteristics of an antipsychotic are difficult to determine from a single registration study. We thus conducted an analysis that assessed key efficacy and tolerability outcomes post hoc from four pooled short-term (4-6 weeks) phase III studies that evaluated iloperidone versus placebo in patients with schizophrenia or schizoaffective disorder. ⋯ Consistent with product labeling, iloperidone 10-16 mg/day or 20-24 mg/day demonstrated significant improvement over placebo on BPRSd and PANSS-T scores, as well as on PANSS-P and PANSS-N subscale scores over 6 weeks of treatment in patients with schizophrenia and in the ITT population, which includes patients with schizoaffective disorder. Iloperidone did not differ from placebo in terms of extrapyramidal disorders and akathisia.
