An Efficacy, Safety And Tolerability Study of Flexibly Dosed Paliperidone Extended-Release (ER) in Participants With Schizophrenia
2014年2月5日 更新者:Johnson & Johnson Taiwan Ltd
An Open-label Prospective Trial to Evaluate the Tolerability, Safety and Maintained Efficacy of a Transition to Paliperidone ER in Subjects With Schizophrenia Previously Unsuccessfully Treated With Other Oral Antipsychotics
The purpose of the study is to explore the maintained efficacy, tolerability, and safety of flexibly dosed 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 unsuccessfully treated with other oral atypical antipsychotic medication.
調査の概要
詳細な説明
This is an open-label (all people know the identity of the intervention), non-randomized (the study drug is not assigned by chance), single arm, multicenter (when more than one hospital or medical school team work on a medical research study), 24-week study.
Participants can be transitioned to an effective dose of paliperidone ER from any oral antipsychotic medication without the need for titration due to lack of efficacy, lack of tolerability or safety, lack of compliance or other reason.
A transition period of maximum 4 weeks will be allowed.
Throughout the study, participants will receive flexible dose of 3 to 12 milligram (mg) of paliperidone once daily orally for 24 weeks.
Dose adjustment will be done as per Investigator's discretion based upon participant's clinical response to and tolerability of the study drug.
Assessments of efficacy will be performed at screening and after 2, 4, 12 and 24 weeks.
Efficacy will primarily be evaluated by means of Positive and Negative Syndrome Scale (PANSS).
Participants' safety will also be monitored throughout the study.

Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 24
時間枠:Baseline, Week 24
|
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.

Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Marder Subscale Scores at Week 24
時間枠:Baseline, Week 24
|
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 (UH/E) subscale and anxiety/depression subscale, each consisting of 4 items with total score range of 4-28.
Higher score indicates greater severity.

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).

Change From Baseline in Total Personal and Social Performance (PSP) Score at Week 24
時間枠:Baseline, Week 24
|
The PSP is 100-point validated clinician-rated scale that assesses degree of difficulty in 4 areas of functioning: socially useful activities, personal and social relationships, self-care, disturbing and aggressive behaviors rated on 6-point scale (1=absent to 6=very severe).Total transformed score from 1 to 100 is generated from raw score based on clinical interpretation of scores generated in 4 areas of functioning, with higher transformed score indicating better function.
Total score is divided into 3 levels: 71-100 (mild difficulty); 31-70 (marked difficulty) and 1-30 (severe difficulty).

時間枠:Baseline, Week 24
|
The GAF is a 100-point tool rating overall psychological, social and occupational functioning of adults.
The higher score range (91-100) refers to a superior functioning in a wide range of activities, and absence of symptoms.
The lower score range (1-10) refers to persistent danger of severely hurting self or others; or persistent inability to maintain minimum personal hygiene; or serious suicidal act with clear expectation of death.

時間枠:Baseline, Week 24
|
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.
A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill participants".

Change From Baseline in Short-Form 36 Health Survey (SF-36) Score at Week 24
時間枠:Baseline, Week 24

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.
