Efficacy and Safety of Once-Monthly Paliperidone Palmitate Long-Acting Injections in Chinese Patients with Early-, Mid-, and Late-Phase Schizophrenia: A Post-Hoc Analysis of Three Phase 4 Studies.

ABSTRACT:

Background

Long-acting injectable (LAI) antipsychotics have improved treatment adherence and continuity compared with oral antipsychotics. However, evidence gaps persist in the endorsement of LAIs for early-phase schizophrenia in China. This post-hoc analysis evaluated the efficacy and safety of once-monthly paliperidone palmitate (PP1M), an LAI antipsychotic, following early-, mid-, and late-phase use in Chinese patients with schizophrenia.

Methods

Data from three phase 4 studies (NCT01527305, NCT01947803, and NCT01685931) were used. Chinese patients with schizophrenia (disease duration early: ≤ 2 years; mid: > 2 to ≤ 5 years; late: > 5 years) who received 13 weeks of PP1M treatment were included. The primary endpoint was change in Positive and Negative Syndrome Scale (PANS
