• Status: Terminated
• Trial end date: 2006-11-01
• Target enrollment: 0
• Participant gender: All

Summary

The primary study objective was to evaluate the dose-dependent efficacy of eslicarbazepine acetate administered at doses of 600, 1200, and 1800 mg over a 3-week period, compared with placebo, as therapy in patients with acute mania. The secondary objectives of this study were to a) evaluate the safety and tolerability of eslicarbazepine acetate (BIA 2-093) administered at doses of 600, 1200, and 1800 mg compared with placebo, b) assess the duration to onset of action in the different dose groups, and c) monitor the appearance of depressive symptoms.
