简要总结
The purpose of this study is to evaluate risperidone long-acting injection (an antipsychotic medication) versus oral antipsychotics in schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self) participants with a history of being poorly compliant with taking their medication.
详细描述
This is a Phase 4, an open-label (all people know the identity of the intervention), multi-country and multi-centric (conducted in more than one center) study of risperidone long-acting formulation versus oral (having to do with the mouth) atypical antipsychotics in participants with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Text revision ( DSM-IV TR) diagnosis of schizophrenia currently being treated with oral antipsychotic medication. The duration of this study will be 2 years. All the eligible participants will be randomly assigned to an oral atypical antipsychotic (risperidone, olanzapine, quetiapine, and where commercially available, aripiprazole and amisulpride) or to risperidone long-acting formulation. For risperidone long-acting formulation participants, study medication will be administered by intramuscular (into the muscle) injection every 2 weeks at doses of 25, 37.5 or 50 milligram (mg). Oral supplementation with the current oral atypical antipsychotic is required for the first 3 weeks following the initial injection and dose increase. Dose increase can be made as per product labeling. The primary measure of effectiveness is the reduction in the percentage of participants experiencing a clinical exacerbation after being in the study for 3 months. Participants' safety will be monitored throughout the study.

研究组 & 干预措施
Risperidone long-acting injection (LAI)
Risperidone LAI 25 milligram (mg), 37.5 mg or 50 mg intramuscular (injection of a substance into a muscle) injection will be administered every 2 weeks as per Investigator's discretion. An oral atypical antipsychotic will also be administered in the first 3 weeks following the dose increase. Duration of treatment will be 24 months.
干预措施: Risperidone long-acting injection (LAI) (Drug)
Oral atypical Antipsychotic
Oral atypical antipsychotic will be administered as per local label practice for 24 months. Participants will be switched to another atypical oral therapy as per Investigator's discretion.
干预措施: Oral atypical Antipsychotic (Drug)
结局指标
主要结局
Percentage of Participants Who Experienced a Clinical Exacerbation From Month 3 Post-Randomization
时间窗: Month 3 up to Month 24
Clinical exacerbation is defined as hospitalization because of participant's schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, delusions, hallucinations, and self withdrawal) or requiring change from current antipsychotic or initiation of adjunctive antipsychotic, 2-point worsening in Clinical Global Impression of Severity (CGI-S) or emergency room visit, deliberate self-injury, emergence of clinically significant suicidal ideation, utilization of treatment team services, violent behavior, requiring an increase in dose of existing antipsychotic as a result of poor symptom control.
