Primary | Percentage of Participants With at Least 20 Percent Improvement in Total Positive and Negative Syndrome Scale (PANSS) Score in Those Participants who Transitioned due to Lack of Efficacy | The PANSS is a 30-item scale to assess the neuropsychiatric symptoms of schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self). The PANSS provides a total score and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each item scored on a scale of 1 (absent) to 7 (extreme). The total score ranges from 30 to 210 and higher score indicates greater severity. | Endpoint (up to Week 26) | |
Primary | Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Endpoint (up to Week 26) | The PANSS is a 30-item scale to assess the neuropsychiatric symptoms of schizophrenia. The PANSS provides a total score and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each item scored on a scale of 1 (absent) to 7 (extreme). The total score ranges from 30 to 210 and higher score indicates greater severity. | Baseline and endpoint (up to Week 26) | |
Secondary | Percentage of Participants With at Least 20 Percent Improvement in Total Positive and Negative Syndrome Scale (PANSS) Score | The PANSS is a 30-item scale to assess the neuropsychiatric symptoms of schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self). The PANSS provides a total score and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each item scored on a scale of 1 (absent) to 7 (extreme). The total score ranges from 30 to 210 and higher score indicates greater severity. | Endpoint (up to Week 26) | |
Secondary | Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Subscale Scores at Endpoint (up to Week 26) | The PANSS is a 30-item scale to assess the neuropsychiatric symptoms of schizophrenia. The PANSS provides a total score and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each item scored on a scale of 1 (absent) to 7 (extreme). Positive subscale score ranges from 7 (absent) to 49 (extreme psychopathology), negative subscale score ranges from 7 (absent) to 49 (extreme psychopathology) and general psychopathology subscale score ranges from 16 (absent) to 112 (extreme psychopathology). | Baseline and endpoint (up to Week 26) | |
Secondary | Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Marder Subscale Scores at Endpoint (up to Week 26) | The PANSS is a 30-item scale to assess the neuropsychiatric symptoms of schizophrenia. The symptoms are rated on a 7-point scale from 1 (absent) to 7 (extreme psychopathology). Marder PANSS subscales include positive symptoms subscale consisting of 8 items with total score range of 8-56; negative symptoms subscale and disorganized thoughts subscale, each consisting of 7 items with total score range of 7-49; and uncontrolled hostility/excitement subscale and anxiety/depression subscale, each consisting of 4 items with total score range of 4-28. Higher score indicates greater severity. | Baseline and endpoint (up to Week 26) | |
Secondary | Change From Baseline in Clinical Global Impression-Severity (CGI-S) Score at Endpoint (up to Week 26) | The CGI-S rating scale assesses the severity of a participant's psychotic condition on a 7-point scale ranging from 1 (not ill) to 7 (extremely severe). | Baseline and endpoint (up to Week 26) | |
Secondary | Change From Baseline in Total Personal and Social Performance (PSP) Score at Endpoint (up to Week 26) | The PSP scale assesses the degree of dysfunction within 4 domains of behavior: socially useful activities, personal and social relationships, self-care and disturbing and aggressive behavior. The score ranges from 1 to 100, divided into 10 equal intervals to rate the degree of difficulty (1, absent to 6, very severe) in each of the 4 domains. Participants with a score of 71 to 100 have a mild degree of difficulty; from 31 to 70, varying degrees of disability; less or equal to 30, functioning so poorly as to require intensive supervision. | Baseline and endpoint (up to Week 26) | |
Secondary | Change From Baseline in Short-Form 36 Health Survey (SF-36) Score at Endpoint (up to Week 26) | The SF-36 is a health status survey with 36 questions measuring 8 dimensions (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health) that are subsequently aggregated into 2 summary scales, Physical Component Summary (PCS) and Mental Component Summary (MCS). Each item is scored into 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. | Baseline and endpoint (up to Week 26) | |
Secondary | Number of Participants With Satisfaction With the Study Treatment | Participants will assess their satisfaction with paliperidone ER on a 5-point scale: 1 (very good), 2 (good), 3 (moderate), 4 (poor) and 5 (very poor). | Endpoint (up to Week 26) | |
Secondary | Change From Baseline in Sleep and Daytime Drowsiness Evaluation Score at Endpoint (up to Week 26) | The Sleep and Daytime Drowsiness Evaluation Scale is a self-administered scale that rates quality of sleep and daytime drowsiness. Participants indicate on an 11 point scale how well they have slept in the previous 7 days, score ranging from 0 (very badly) to 10 (very well) and how often they have felt drowsy within the previous 7 days, score ranging from 0 (not at all) to 10 (all the time). | Baseline and endpoint (up to Week 26) | |
Secondary | Change From Baseline in Extrapyramidal Symptoms Rating Scale (ESRS) Total Score at Endpoint (up to Week 26) | The ESRS scale assesses parkinsonism (slow movements), dystonia (abnormal muscle movement causing focal/generalized, sustained muscle contractions, postures, and involuntary movements) and dyskinetic (involuntary muscle contractions) movement subscale. Parkinsonism consists of 8 items rated on a 7-point scale (0=absent/normal and 6=worst score), Dystonia consists of 2 items rated on a 7-point scale (0=absent and 6=extremely severe) and Dyskinetic movements consists of 7 items rated on a 7-point scale (0=none and 6=worst score). Total score: 0-102. Lower scores indicate better condition. | Baseline and endpoint (up to Week 26) |
