[4] Patients must: • have a PANSS score more than or equal to 60 at Visit 1 and Visit 2; and • have a history of unsatisfactory clinical response to antipsychotic treatment for schizophrenia (except when treated with olanzapine or haloperidol). For this study, unsatisfactory clinical response is defined as persistent hallucinations, delusions, or thought disorder after at least 6 weeks of contiguous treatment (as supported by patient, medical, or family reports), with a therapeutic dose of at least 1 antipsychotic used for schizophrenia, not including haloperidol or olanzapine; and • have demonstrated poor functioning in the past year in at least 2 areas of the patient’s life, such as occupational (work/school/vocational), social (interpersonal relations, whether problems within the family or outside the home), or self care. [5] Each patient must be reliable, have a level of understanding sufficient to perform all tests and examinations required by the protocol, understand the nature of the study, and have given informed consent. [6] Patients must have experienced at least 2 episodes of clinical worsening of schizophrenia symptoms in the past 12 months such that hospitalization or increased levels of care were required. Increased levels of care can include the addition of or change to any of the following from a lower level of care: day hospital program, outpatient crisis management, short-term psychiatric treatment in an emergency room, or an addition, increase, or switch of medication. [7] Patients must have experienced AEs to current antipsychotic treatment or have been nonadherent to current antipsychotic therapy (this includes patient nonadherent to haloperidol or oral olanzapine) such that the patient and the treating physician desire a change to the patient’s therapy

Primary Outcome(s)

Primary end point(s): Time to all-cause discontinuation for up to 52 weeks in the treatment of symptomatic outpatients with schizophrenia who are at risk for relapse due to nonadherence, and who have previously had an unsatisfactory treatment response. Time to all-cause discontinuation is defined as the total number of days between the date of first depot dose (Visit 3) and the date of study discontinuation. Superiority of OP Depot treatment group will be assessed using the log-rank test from the Kaplan-Meier survival analysis.

Secondary Objective: to evaluate the incidence of all-cause discontinuations of patients on OP Depot compared with haloperidol decanoate, to assess -improvement in the psychopathology of schizophrenia, -improvement in depressive symptoms, -mean change from baseline to Week 8 and to endpoint in the Clinical Global Impression-Severity (CGI-S) score -improvement in the psychopathology of schizophrenia, -to evaluate the response rate at Week 8 and endpoint for patients on OP Depot compared with haloperidol decanoate, with response defined as a 30% or greater improvement from the baseline PANSS Total score -to evaluate the efficacy of OP Depot compared with haloperidol decanoate in time to relapse and incidence of relapse in the subgroup of patients -to evaluate the incidence of remission of patients treated with OP Depot compared with haloperidol decanoate.

Main Objective: The primary objective of this study is to evaluate whether OP Depot is superior to haloperidol decanoate in terms of overall effectiveness as measured by the time to all-cause discontinuation for up to 52 weeks in the treatment of symptomatic outpatients with schizophrenia who are at risk for relapse due to nonadherence, and who have previously had an unsatisfactory treatment response. Time to all-cause discontinuation is defined as the total number of days between the date of first depot dose (Visit 3) and the date of study discontinuation. Superiority of OP Depot treatment group will be assessed using the log-rank test from the Kaplan-Meier survival analysis.
