Primary Outcome Measures:

Change from baseline to Day 21 in the total Young Mania Rating Scale (YMRS) score.

Secondary Outcome Measures:

Change from baseline to Day 21 and Week 12 in scores of MADRS, BPRS, CGI, and GAS. Response to treatment, indicated by no longer meeting DSM-IV criteria for manic/mixed episode. Incidence of adverse events monitored throughout the study.

Detailed Description:

This is a randomized, double-blind, placebo- and active-controlled study to evaluate the effectiveness of two dose levels of topiramate (200 and 400 milligrams/day) compared with lithium and placebo in the treatment of acute manic or mixed episodes in patients with Biplar I Disorder. The trial consists of 3 phases: a screening period; double-blind treatment for 12 weeks; and an optional open-label period of at least 6 months. Efficacy assessments include the change from baseline to Day 21 for the total Young Mania Rating Scale (YMRS) score. Also included as efficacy assessments during the 12 week study are the Global Assessment Scale (GAS), Montgomery-Åsberg Depression Rating Scale (MADRS), Brief Psychiatric Rating Scale (BPRS), Clinical Global Impressions (CGI), and health-related quality of life measures at specified time intervals. Safety assessments include evaluation of adverse events throughout the study, rate of withdrawal from the study due to adverse events, and vital signs (blood pressure and pulse) througout the study, as well as changes in clinical laboratory tests (hematology, chemistry, urinalysis), electrocardiograms (ECGs), and physical examinations at specified times. The study hypothesis is that the change from baseline in Young Mania Rating Scale (YMSR) total score at Day 21 will be significantly better for the topiramate groups than for the placebo group and that the study drug will be well tolerated by the patients. Topiramate: oral tablets (50 milligrams[mg]); increasing from once daily (50mg) to 3-times daily; target total daily dose 200mg or 400mg, maintained through Week 12. Lithium: oral capsules (300mg); increasing from once daily (300mg) to three-times daily; target total daily dose 1500-1800 mg.
