Arms Assigned Interventions
Experimental: Asenapine
Flexible-dose asenapine
Drug: Asenapine
One flavored asenapine sublingual tablet twice daily (BID) starting at 2.5 mg on Day 1 for three consecutive days. Normally on Day 4, the dose will increase to 5 mg BID beginning with the evening dose. Normally on Day 7, the dose will increase to 10 mg BID beginning with the evening dose. The dose may be up-titrated earlier than Days 4 and 7 at the investigator's discretion. Beginning on Day 8 (or after at least 1 day on 10 mg BID), asenapine dosing will be flexible (2.5, 5, or 10 mg BID) until up to Week 50.
Other Name: SCH 900274, ORG 5222
Drug: Rescue medication
For participants whose symptoms worsen or are not adequately controlled on assigned treatment, rescue medication may be administered during the trial in the following circumstances. For the control of agitation, anxiety, insomnia, restlessness, or akathisia and extrapyramidal symptoms (EPS) some benzodiazepines (i.e., lorazepam [up to 4 mg/day] or an equivalent dose of short-acting benzodiazepines) and EPS medications (i.e., anticholinergics) are allowed. Benadryl (diphenhydramine) and beta blockers are also permitted, provided that they are not taken within 8 hours of efficacy assessments.
