Study to Assess the Safety, Tolerability and Pharmacokinetics of Oral Brexpiprazole (OPC- 34712) in Adolescents With Schizophrenia

Subjects who are deemed eligible for the trial will be assigned to a dosing cohort and will enter a Dose Titration Phase during which they will receive a starting dose of brexpiprazole for 2 to 10 days based on their assigned titration schedule. The Dose Titration Phase may be extended up to a maximum of 14 days, based on the observed safety and tolerability profile of the previous cohort's Dose Titration Phase. Following the Dose Titration Phase, subjects will enter the Fixed Dose Phase and will be administered the assigned dose for that cohort for 14 days.
