Intramuscular Depot Formulation of Aripiprazole as Maintenance Treatment in Patients With Schizophrenia

The purpose of the this trial is to evaluate the efficacy, safety, and tolerability of an intramuscular (IM) depot formulation of aripiprazole as maintenance treatment in patients with schizophrenia The trial is designed into three treatment phases. Phase 1 is designed to allow for a subject to be converted from the current anti-psychotic treatment to oral non-generic aripiprazole monotherapy (oral conversion phase from 4 to 6 weeks). During Phase 2 the subject will be stabilized on oral non-generic aripiprazole monotherapy. Once the subject is stabilized in Phase 2 (oral stabilization phase from minimum 8 weeks to maximum 28 weeks), they are eligible to be randomized into the double-blind IM depot maintenance phase, Phase 3. During Phase 3, the subject will be assessed for exacerbation of psychotic symptoms and impending relapse for up to 38 weeks.
