  Purpose

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 objective of the trial is to measure the improvement of the participant's manic symptoms (as measured by Young Mania Rating Scale [YMRS]) at Day 21 of the trial.
