Abstract

OBJECTIVE:

The objective of this open-label study was to assess the safety of divalproex sodium extended-release in the treatment of children and adolescents with acute mania associated with bipolar I disorder.

METHODS:

This was a 6-month, Phase 3, open-label study in healthy subjects aged 9-17 years with a current Diagnostic and Statistical Manual of Mental Disorders, 4(th) edition, Text Revision (DSM-IV-TR) diagnosis of bipolar I disorder manic or mixed episode. Divalproex sodium extended-release (DVPX-ER) was initiated at 15 mg/kg per day on day 1 (not to exceed 750 mg/day) with increases allowed to a maximum of 35 mg/kg per day. Study visits were conducted on day 1 and at months 1, 2, 3, and 6. Assessments included standard safety evaluations and appropriate rating scales for clinical effect.

RESULTS:

A total of 226 subjects were enrolled; 109 subjects completed the study. The most common adverse events were weight gain (16%), nausea (9%), and increased appetite (8%). Nonsymptomatic elevations of mean ammonia levels in plasma were observed. The mean Young Mania Rating Scale (YMRS) decreased 12.4 from baseline to final visit; small improvements were seen in behavior and caregiver stress ratings.

CONCLUSIONS:

DVPX-ER was generally well tolerated in children and adolescents with acute mania, with a side-effect profile similar to that observed in adults.
