A Study of Flexibly Dosed Paliperidone Extended Release Tablets in Participants With Schizophrenia

Schizophrenia Clinical Trial

Official title: An Open-label Prospective Trial to Explore the Tolerability, Safety and Efficacy of Flexibly Dosed Paliperidone ER in Non Acute Episode Subjects With Schizophrenia

Status Completed

Clinical Trial Summary

The purpose of this study is to evaluate the effectiveness of paliperidone extended-release (ER; designed to slowly release a drug in the body over an extended period of time) tablets in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions [a false belief held in the face of strong differing evidence, especially as a symptom of psychiatric disorder] and hallucinations [imagining things], and withdrawal into the self) who were not satisfied with other prior antipsychotics (agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect; olanzapine, quetiapine and risperidone) they had been taking. The safety and tolerability of paliperidone ER tablets will also be assessed.

Clinical Trial Description

This is an open label (all people know the identity of the intervention), prospective (study following participants forward in time), non-randomized (the study drug is not assigned by chance, participants may choose which group they want to be in, or they may be assigned to the groups by the researchers), single-arm (getting one dose of medicine) and multi-center (when more than one hospital or medical school team work on a medical research study) study designed to determine the efficacy, tolerability and safety of flexible dosage of paliperidone ER tablets in treatment of participants with schizophrenia not satisfied with other prior antipsychotics. The duration of the study will be 12 weeks. All participants will be given paliperidone ER 3 milligram (mg) or 6 mg or 9 mg or 12 mg oral (by mouth) tablets depending on Investigator's discretion once daily for 12 weeks; initial dose for paliperidone ER will be 6 mg/day. The primary objective will be to evaluate the efficacy of treatment with paliperidone ER using Positive and Negative Symptom Scale (PANSS) total scores. Participants safety and tolerability will be monitored throughout the study. ;
