Safety and Tolerability of Aripiprazole in Adolescents With Schizophrenia or Children and Adolescents With Bipolar I Disorder, Manic or Mixed Episode With or Without Psychotic Features.

This is an open-label study consisting of a screening period, a conversion/titration phase (Phase 1), an open-label treatment phase (Phase 2), and a follow-up period.

The study will enroll new subjects (hereafter referred as "de novo" subjects) with schizophrenia, or bipolar I disorder, manic or mixed episode with or without psychotic features, and rollover subjects with schizophrenia from 31-09-266 (hereafter referred to as "Study 266"). All de novo subjects must enter the screening period of the study. Subjects who are screened and are not required to go through Phase 1 will complete a Phase 2 baseline visit prior to their participation in Phase 2.
