PaliperidoNe Extended-Release [ER] Dosing and Clinical Response in Acute Schizophrenia (PANDORA)

January 22, 2014 updated by: Janssen Korea, Ltd., Korea

An Open Label, Prospective, Non-comparative Study to Evaluate Flexible Dose of Paliperidone Extended-Release and Clinical Response in the Treatment of Subjects With Schizophrenia

The purpose of this study is to evaluate the efficacy 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).

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 (all people know the identity of the intervention), multi-centric (conducted in more than one center), prospective (study following participants forward in time), single arm, and non-comparative study of paliperidone Extended Release(ER) in participants with schizophrenia. The total study duration will be approximately of 104 weeks per participant. The study consists of following parts: Screening (that is, 14 days before study commences on Day 1); acute Treatment phase (single-oral dose of paliperidone for 12 weeks, dose ranging from 3 to 12 milligram); Extension phase 1 (12 weeks) and Maintenance treatment which will be followed by additional Extension phase 2 and long-term maintenance treatment. Efficacy of the participants will primarily be evaluated by Clinical Global Impression-Improvement (CGI-I) scale score. Participants' safety will be monitored throughout the study.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

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
Percentage of Participants Assessed as Very Much Improved or Much Improved Based on Clinical Global Impression-Improvement (CGI-I) Scale - Intent-to-treat (ITT) Population
Time Frame: Week 12
The CGI-I is a 7-point scale that requires the clinician to assess how much the participant's illness has improved or worsened relative to a baseline state at the beginning of the intervention and rated as: 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse.
Week 12
Percentage of Participants Assessed as Very Much Improved or Much Improved Based on Clinical Global Impression-Improvement (CGI-I) Scale - Per Protocol (PP) Population
Time Frame: Week 12
The CGI-I is a 7-point scale that requires the clinician to assess how much the participant's illness has improved or worsened relative to a baseline state at the beginning of the intervention and rated as: 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse.
Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Personal and Social Performance (PSP) Scale Score - Intent-to-treat (ITT) Population
Time Frame: Baseline, Week 4 and 12
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, Week 4 and 12
Personal and Social Performance (PSP) Scale Score - Per Protocol (PP) Population
Time Frame: Baseline, Week 4 and Week 12
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, Week 4 and Week 12
Percentage of Participants Continuously Treated With 6 Milligram Per Day Regimen Until Week 12 - Intent-to-treat (ITT) Population
Time Frame: Week 12
Percentage of participants who were continuously treated with paliperidone extended-release (ER) 6 milligram per day regimen until Week 12 are reported here.
Week 12
Percentage of Participants Continuously Treated With 6 Milligram Per Day Regimen Until Week 12 - Per Protocol (PP) Population
Time Frame: Week 12
Percentage of participants who were continuously treated with paliperidone extended-release (ER) 6 milligram per day regimen until week 12 are reported here.
Week 12
Drug Attitude Inventory (DAI) Score - Intent-to-treat (ITT) Population
Time Frame: Baseline, Week 4 and 12
The DAI-10 is a 10-item questionnaire to assess 1) subjective experience of drug and 2) attitudes and beliefs toward neuroleptics which may influence compliance in schizophrenia participants. It is the binary scale assessing the participant's subjective response. A 'compliant' response is scored as +1; a dysphoric response is scored as -1. A positive sum of items indicates a positive subjective response (SR); a negative sum of scores indicates a negative SR (non-compliant). The final score is the grand total of the positive and negative points. Total score ranges from (-) 10 to (+) 10, higher score indicates positive SR (compliant) and lower score indicates negative SR (non-compliant).

Baseline, Week 4 and 12
Clinical Global Impression - Severity (CGI-S) Score - Intent-to-treat (ITT) Population
Time Frame: Baseline, Week 2, 4, 8 and 12
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". Higher scores indicate worsening.
