Official title

A Randomized, Double-Blind, Active- and Placebo-controlled, Parallel-group, Multicenter Study to Evaluate the Efficacy and Safety of Extended-Release Paliperidone as Maintenance Treatment After an Acute Manic or Mixed Episode Associated With Bipolar I Disorder

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to evaluate the effectiveness and safety of oral extended-release (ER) paliperidone compared with placebo in the prevention of the recurrence of mood symptoms in patients with Bipolar I Disorder who initially respond to treatment of an acute manic or mixed episode with paliperidone ER. Olanzapine was included as an active control arm, although the study is not designed to allow for a direct comparison of olanzapine with paliperidone.
