Open-label, Extension Study of Aripiprazole Intramuscular Depot (OPC-14597, Lu AF41155) in Patients With Schizophrenia

Study Overview
=================
Brief Summary
-----------------
The phase 3 Trial 31-12-291 is part of the aripiprazole IM depot clinical development program and has been designed to demonstrate the efficacy and safety of aripiprazole IM depot for the treatment of adults experiencing an acute relapse of schizophrenia. Subjects receive treatment during a 12-week double-blind acute treatment phase. The current trial (31-12-297) will allow the subjects who complete Trial 291 to enter this open label trial at the investigator's discretion, where additional safety and tolerability data will be collected.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Reporting Treatment Emergent Adverse Events (TEAEs), Severe TEAEs, Discontinued Investigational Medicinal Product (IMP) Due to AEs, Serious TEAEs and Outcome of Death | A TEAE was defined as an AE that began after the first injection or was continuous from Baseline and was serious, study drug-related, or resulted in death. | Baseline to Week 24 | 

Secondary Outcome Measures
