Fixed-dose Safety and Efficacy Study of Asenapine for the Treatment of Acute Manic or Mixed Episode in Bipolar 1 Disorder (P05691)

367 participantsStarted 2012-04-06

Plain-language summary

This trial will study the efficacy and safety of a fixed dose of asenapine in participants diagnosed with Bipolar 1 Disorder. Participants who qualify for the study will be randomly assigned to receive a fixed dose of asenapine (either 5 mg or 10 mg twice daily \[BID\]) or placebo (BID) for 3 weeks. Throughout the trial, observations will be made on each participant at various times to assess the safety and effectiveness of the study treatment. The primary hypothesis is that there is at least one dose of asenapine that is superior to placebo in the change from baseline in manic symptoms (as measured by Young Mania Rating Scale \[YMRS\]) at Day 21 of the trial.
