Fixed-dose Safety and Efficacy Study of Asenapine for the Treatment of Acute Manic or Mixed Episode in Bipolar 1 Disorder (P05691)
- Registration Number
- NCT00764478
- Lead Sponsor
- Organon and Co
- Brief 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.

- Primary Outcome Measures
Name Time Method Change From Baseline in Young Mania Rating Scale (Y-MRS) Total Score at Day 21 Baseline and Day 21 Y-MRS consists of responses to the following 11 items: elevated mood, increased motor activity energy, sexual interest, sleep, language-thought disorder, appearance, insight, irritability, speech - rate and amount, content and disruptive-aggressive behavior. The scores from the 11 items are summed to give a total score ranging from 0 to 60, with a higher score indicating greater severity of symptoms. The analysis is based on a mixed model repeated measures (MMRM) model. An improvement in symptoms is represented by change from baseline values that are negative.
- Secondary Outcome Measures
Name Time Method Change From Baseline in Clinical Global Impression - Bipolar Mania - Severity of Illness (CGI-BP-S) Overall Score at Day 21 Baseline and Day 21 The CGI-BP-S is a score that measures the severity of overall bipolar illness. The score ranges on a scale from 1 to 7, where 1 is normal, and 7 is very severely ill. The analysis is based on a MMRM model.
