Objectives The goal of this study was to investigate the safety and efficacy in preventing relapse of a mood episode in recently manic or mixed episode patients with bipolar I disorder stabilized with aripiprazole and divalproex combination. Methods This randomized, 24‐week, double‐blind, placebo‐controlled multicenter study enrolled patients from 23 centers in Korea. Patients with bipolar I disorder who had manic or mixed episode entered a 6‐week open‐label stabilization phase. After meeting stabilization criteria, 83 patients were randomly assigned to placebo + divalproex or aripiprazole + divalproex treatment group for the 24‐week, double‐blind maintenance phase. Results During the 6‐month double‐blind treatment, the time to relapse of any mood episode in the aripiprazole group was longer than the placebo group, but the difference did not reach statistical significance ( p = 0.098). After controlling for mean divalproex level, the time to depressive episode relapse in the aripiprazole group was longer than those in the placebo group ( p = 0.029). Weight gain (≥7% increase) occurred in 22.5% aripiprazole group and 18.6% placebo group ( p = 0.787). Conclusions In this study, relapse of mood episode occurred fewer and later for aripiprazole with divalproex treatment than divalproex monotherapy, but the differences were not statistically significant.
