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

Study Overview
=================
Brief 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.

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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 26 - Main Phase | 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. | Baseline and Week 26 | 
| Change From Baseline in PANSS Total Score at Week 52 - Main Phase Plus Extension Phase | 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. | Baseline and Week 52 |

| Change From Baseline in Personal and Social Performance (PSP) Scale Score at Week 4, 8, 13 and 26 - Main Phase | The PSP scale evaluates the dysfunction degree exhibited by the participants, regarding 4 behavioral domains: useful social activities, personal and social relations, self-care and agitated and aggressive behavior. Each domain were assessed on a 6-point scale (0=absent to 5=very severe). A transformed score from 1 to 100 is generated from the raw score based on the clinical interpretation of the scores generated in the 4 areas of functioning, with a higher transformed score indicating better function. | Baseline, Week 4, 8, 13 and 26 |

| Change From Baseline in Pittsburg Sleep Quality Index (PSQI) Score at Week 4, 8, 13 and 26 - Main Phase | The PSQI evaluates sleep behavior by means of 7 components: sleep quality, sleep latency, sleep duration, usual sleep efficiency, sleep disorders, use of sleep medication and daytime dysfunction. The sum of the 7 component scores produces a global score of subjective sleep quality that varies from 0 to 21, with higher scores indicating worse sleep quality. | Baseline, Week 4, 8, 13 and 26 |

The sum of the 7 component scores produces a global score of subjective sleep quality that varies from 0 to 21, with higher scores indicating worse sleep quality. | Baseline, Week 4, 8, 13, 26, 39 and 52 | 
| Number of Participants With Clinical Global Impression-Severity (CGI-S) Score - Main Phase | The CGI-S rating scale is a 7-point global assessment that measures the clinician's impression of the severity of illness exhibited by a participant.The categories included in the scale are normal, without any disease, borderline, slightly ill, moderately ill, markedly ill, severely ill and extremely ill. A rating of 1=Normal, not at all ill and a rating of 7 =Among the most extremely ill participants. Higher scores indicate worsening. | Baseline, Week 4, 8, 13 and 26 |

| 36-Item Short-Form Health Survey (SF-36) Score - Main Phase | 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. | Baseline and Week 26 |

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.
