One-Year Open-Label Safety and Efficacy Study of Paliperidone Extended-Release Tablets in Patients With Schizophrenia

Published online by Cambridge University Press:  07 November 2014

Abstract

Introduction: This 52-week open-label extension (OLE) to a double-blind placebo-controlled recurrence prevention study examined the long-term safety and efficacy of flexibly-dosed paliperidone extended-release (ER) tablets in patients with schizophrenia.

Methods: Patients entering the OLE either entered from the double-blind phase (placebo or paliperidone ER treatment) or entered directly from the run-in or stabilization phase (paliperidone ER) of the earlier study. During the OLE, patients were treated with flexibly-dosed paliperidone ER (3–15 mg/day; 9 mg starting dose). Safety and tolerability assessments included incidence of adverse events and extrapyramidal symptoms. Efficacy was also assessed.

Results: The study population (n=235) was predominantly men (66%), 18–58 years of age. Twelve patients (5%) experienced an adverse event requiring treatment discontinuation. One or more serious treatment-emergent adverse events were reported in 13 patients (6%). There was one death. The mean Positive and Negative Syndrome Scale total score decreased from open-label baseline to endpoint for all groups, regardless of previous double-blind treatment (placebo or paliperidone ER).

Conclusion: This year-long OLE provides information on the long-term safety and tolerability of paliperidone ER in patients with schizophrenia. The resulting safety and tolerability profile was similar to that seen in earlier short-term studies.
