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

September 17, 2013 updated by: Janssen-Cilag Farmaceutica Ltda.

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

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 26 - Main Phase
Time Frame: Baseline and Week 26
The PANSS is a 30-item scale designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and poor impulse control. The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score consists of the sum of all 30 PANSS items and ranges from 30 to 210. Higher scores indicate worsening.

The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score consists of the sum of all 30 PANSS items and ranges from 30 to 210. Higher scores indicate worsening.

The SF-36 is designed to assess the health status of participants. The SF-36 includes 1 multi-item scale measuring physical health component and mental health component. Physical health component includes physical functioning, role limitations due to physical health, pain and general health. Mental health component includes role limitations due to emotional problems, energy/fatigue, emotional well being and social functioning. Each item is scored on a 0-100 range so that the lowest and highest possible scores are set at 0 and 100, respectively. All items are scored so that a high score defines a more favorable health state. The score for a component (physical or mental) is an average of the individual item scores. Each component is scored on a scale of 1 to 100, where 100=highest level of functioning.
