Efficacy and safety of oral paliperidone extended-release tablets in the treatment of acute schizophrenia: pooled data from three 52-week open-label studies.
Long-term efficacy and safety of paliperidone extended-release tablets (3-12 mg/day) were evaluated in pooled data from 52-week open-label extension (OLE) phases of three 6-week, placebo-controlled, double-blind (DB) trials involving 1083 schizophrenia patients. Forty-seven percent of patients completed the OLE phase. Outcome measures included Positive and Negative Syndrome Scale and Personal and Social Performance scale scores. Improvements observed on both scales in active treatment groups during the DB phases were maintained during the OLE phase. Most commonly (> or =10% patients) reported adverse events (AEs) were insomnia, headache, and akathisia. One or more serious AEs were reported by 16% of patients; two patients had a treatment-emergent AE that resulted in death (suicide). Extrapyramidal symptom-related AEs were reported by 25% of patients. Median maximum movement disorder rating scale scores indicated no severity change during the OLE. Mean (+/-SD) increase in body weight from OLE baseline to end point was 1.1+/-5.47 kg across treatment groups and there were no clinically meaningful changes for plasma glucose, insulin or lipid levels. This analysis shows that paliperidone extended-release can maintain improvements in symptoms and functioning and is generally well tolerated for up to 52 weeks in schizophrenia patients.
