Brief summary
This study is an open label, sequential-group, two site, multiple dose escalating study of sublingual administered asenapine in a pediatric population with schizophrenia or bipolar I disorder; in one study cohort (3a) participants with other conditions treatable with chronic antipsychotic medication can also be enrolled. Participants will receive a single sublingual placebo dose on Day -1, followed by multiple sublingual doses of asenapine twice daily (b.i.d.) for 6 days (Cohorts 1 and 2), 7 days (Cohort 3b-d), or 11 days (Cohort 3a), and a final once daily administration on Day 7 (Cohorts 1 and 2), Day 8 (Cohort 3b-d) or Day 12 (Cohort 3a).
Interventions
Asenapine tablet, sublingually (SL), 2.5 mg b.i.d. on Days 1-6 and one 2.5 mg tablet, SL, on Day 7.
Asenapine tablet, SL, 5 mg b.i.d. on Days 1-6 and one 5 mg tablet, SL, on Day 7.
Asenapine tablets, SL, in a rising dose schedule to 10 mg b.i.d. (with a single 10 mg dose on final day). For Cohorts 3b, 3c and 3d, rising dose schedule begins with asenapine 5 mg b.i.d. on Day 1 and dosing occurs through Day 8. For Cohort 3a, rising dose schedule begins with asenapine 2.5 mg b.i.d. on Day 1 and dosing occurs through Day 12.
