|Official Title:||A Comparison of Long-Acting Injectable Medications for Schizophrenia|
- Efficacy Failure [ Time Frame: 24 months ]Efficacy failure as indicated by psychiatric hospitalization, need for crisis intervention, clinical decision that oral antipsychotic medication cannot be discontinued in less than eight weeks, a clinical decision to discontinue the medication due to inadequate benefit, or the ongoing or repeated need for adjunctive antipsychotic medication.
- Changes in Psychiatric Symptoms [ Time Frame: Baseline to 6 months ]The Positive and Negative Syndrome Scale measures the core symptoms associated with schizophrenia. The measure includes 30 items rated from 1=absent to 7=extremely severe. Full range of scores is 30-210 with higher scores representing more severe illness. Reductions in symptoms over time represent improvement.

The purpose of this comparative effectiveness research study is to learn more about different medications called antipsychotics that are used to treat schizophrenia or schizoaffective disorder. Specifically, we are looking at long-acting medications that are given by injection every month, instead of being taken by mouth every day. In this multi-site study, we are comparing the risk and benefits of two FDA-approved long-acting injectable medications (paliperidone palmitate and haloperidol decanoate). Study participants with schizophrenia or schizoaffective disorder are expected to benefit from the improved medication schedule.
This study aims to enroll 360 individuals with schizophrenia or schizoaffective disorder for whom treatment with a long-acting injectable antipsychotic medication is likely to be helpful. Study participants will be randomly assigned to treatment with either paliperidone palmitate and haloperidol decanoate for up to 24 months. Participants will have an equal chance of being assigned to each medication, however participants will not know which medication they are taking.
