A Study to Evaluate Participants Satisfaction, Quality of Life and Effectiveness of Flexible-Dose of Paliperidone Extended Release (ER) in Participants With Schizophrenia, Previously Treated With Risperidone

Schizophrenia Clinical Trial

Official title:
A Study to Evaluate Switching From Risperidone to Paliperidone ER (Extended Release) in the Treatment of Stable But Symptomatic Schizophrenia Outpatients: Patients Satisfaction and Quality of Life

Clinical Trial Summary

The purpose of this study is to evaluate effectiveness, tolerability (how well a participant can stand a particular medicine or treatment), and safety of flexible-dose of paliperidone extended release (ER) in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self), previously taking risperidone (an antipsychotic), but who are not satisfied with their treatment.

Clinical Trial Description

This is an open-label (a medical research study in which participants and researchers are told which treatments the participants are receiving, "unblinded"), multi-center (when more than 1 hospital or medical school team work on a medical research study), non-randomized, single-arm study of paliperidone ER in participants previously treated with risperidone with poor response. The study will consist of 2 phases: a main phase of 6 months and an extension phase of another 6 months. The total duration of the study will be 12 months. All participants will receive an oral (having to do with the mouth) daily dose of paliperidone ER in flexible dosage (in the range of 3-12 milligram [mg]: 3 mg, 6 mg, 9 mg, or 12 mg) according to Investigator's discretion. Efficacy and safety of participants will primarily be evaluated by Positive and Negative Syndrome Scale (PANSS) and Extrapyramidal Symptoms Rating Scale (ESRS), respectively. Participants' safety will be monitored throughout the study. ;
