Secondary Endpoint: Change in Mean PANSS Total Score Over Time2


PANSS=Positive and Negative Syndrome Scale.

*Population included adults diagnosed within 5 years of study entry.

Indicated for the treatment of schizophrenia in adult patients after they have been adequately treated with INVEGA SUSTENNA® (1-month paliperidone palmitate) for at least four months.

Study Design

A randomized, double-blind, placebo-controlled, long-term maintenance study compared 3-month paliperidone palmitate (INVEGA TRINZA®) with placebo in adult patients with schizophrenia. Patients were treated for 17 weeks with 1-month paliperidone palmitate (INVEGA SUSTENNA®) during an open-label, flexible-dose stabilization phase, and then a single dose of INVEGA TRINZA® during an open-label maintenance phase. This was followed by a fixed dose of INVEGA TRINZA® or placebo once every 3 months in a variable-duration, double-blind phase. A preplanned interim analysis conducted by an Independent Data Monitoring Committee after 42 relapse events resulted in the decision to terminate the study early due to significant efficacy favoring INVEGA TRINZA®. The secondary endpoint of PANSS total score is based on final analysis.1,2
