Brief Summary
The primary objective of this trial was to characterize the long-term (up to 40 weeks) safety and tolerability of asenapine in bipolar I disorder subjects who had not completely responded to continuing treatment with lithium or valproic acid (VPA) for the treatment of an acute manic or mixed episodes upon enrollment into the 12-week lead-in trial, A7501008 (NCT00145470). The safety comparison was between the group receiving lithium or VPA and placebo against the group receiving lithium or VPA and asenapine, with the caveat that all subjects may have received benzodiazepine and/or antidepressant rescue medication as needed.

Outcome Measures
Primary Outcomes (4)
Number of Participants Who Experienced an Adverse Event
Participants who experienced treatment-emergent adverse events, defined as adverse events reported on or after the first dose of study medication in the 12-week lead-in study through the last dose of study drug + 7 days (or + 30 days for serious adverse events).
up to 52 weeks
Number of Participants Who Discontinued Because of an Adverse Event
Participants who discontinued study medication due to adverse events.
40 weeks
Change From Baseline to Week 52 on the Young-Mania Rating Scale (Y-MRS) Score
The Y-MRS is an 11-item, clinician-rated instrument used for assessing the symptoms of mania. Y-MRS total score range = 0-60; higher scores indicate greater severity of symptoms.
Baseline and 52 Weeks
Change From Baseline to Week 52 on the Montgomery Asberg Depression Rating Scale (MADRS) Score
The MADRS is a 10-item clinician-rated scale for assessing the severity of symptoms of depression. MADRS total score range = 0-60; higher scores indicate greater severity of symptoms.
