Title: A 52-week, Multicenter, Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy, Safety, and Tolerability of an Intramuscular Depot Formulation of Aripiprazole as Maintenance Treatment in Patients With Schizophrenia
Brief Summary: The purpose of the trial was to evaluate the efficacy, safety, and tolerability of an intramuscular depot formulation of aripiprazole as maintenance treatment in patients with schizophrenia.

The trial was designed into 4 treatment phases. Phase 1 was designed to allow for a patient to be converted from their current antipsychotic treatment to oral non-generic aripiprazole monotherapy (oral conversion phase from 4 to 6 weeks). During Phase 2, the patient was stabilized on oral non-generic aripiprazole monotherapy (oral stabilization phase from a minimum of 4 weeks to a maximum of 12 weeks). Once the patient was stabilized in Phase 2, they entered Phase 3, the single-blind intramuscular (IM) depot aripiprazole stabilization phase. The goal of the phase was to stabilize the patient on the IM depot aripiprazole formulation for a minimum of 12 weeks to a maximum of 36 weeks. When the patient was stabilized, they were eligible to be randomized into the double-blind IM depot maintenance phase (Phase 4). During Phase 4, the patient was assessed for exacerbation of psychotic symptoms and/or impending relapse for up to 52 weeks.
