April 10, 2014 updated by: Janssen Pharmaceutical K.K.

A Placebo-Controlled Double Blind Comparative Study of JNS007ER in Patients With Schizophrenia

The purpose of this study is to evaluate the effectiveness and safety of Extended Release Osmotic Controlled-Release Oral Delivery System (OROS) Paliperidone compared to placebo in patients with Schizophrenia. Olanzapine will be used as a reference drug in the study.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Completed

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 a multicenter, double blind (neither the patient nor the physician knows whether drug or placebo is being taken, or at what dosage), randomized (patients are assigned different treatments based on chance), placebo- and active-controlled, parallel-group study. Patients will be randomized into 1 of 3 treatment groups to receive oral dosages of Extended Release (ER) Osmotic Controlled-Release Oral Delivery System (OROS) paliperidone 6 mg, olanzapine 10 mg, or placebo. They will receive two capsules of Paliperidone ER 3 mg, placebo or Olanzapine 5 mg once daily after breakfast for 6 weeks. The study will include a screening period, followed by double-blind treatment for 6 weeks.

Phase

Phase

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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.

Ages Eligible for Study

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for 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 the Total Positive and Negative Syndrome Scale (PANSS).
Time Frame: Baseline and 6 weeks
PANSS is a medical scale that assesses various symptoms of schizophrenia. The symptoms are rated on a 7-point scale from 1 (absent) to 7 (extreme psychopathology). The total score is the sum of all 30 PANSS items, with a range of 30 (absent) to 210 (extreme ill).
Baseline and 6 weeks

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
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) - Positive Subscale Score
Time Frame: Baseline and 6 weeks
The PANSS Positive Subscale assesses seven positive-symptoms of schizophrenia. Positive symptoms refer to an excess or distortion of normal functions. The symptoms are rated on a 7-point scale, with a range of 7 (absent) to 49 (extreme psychopathology).
Baseline and 6 weeks
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) - Negative Subscale Score
Time Frame: Baseline and 6 weeks
The PANSS Negative Subscale assesses seven negative-symptoms of schizophrenia. Negative symptoms represent a diminution or loss of normal functions. The symptoms are rated on a 7-point scale, with a range of 7 (absent) to 49 (extreme psychopathology).
Baseline and 6 weeks
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) - General Psychopathology Subscale Score
Time Frame: Baseline and 6 weeks
The PANSS General Psychopathology Subscale Score assesses 16 general psychopathology symptoms. The symptoms are rated on a 7-point scale, with a range of 16 (absent) to 112 (extreme psychopathology).
Baseline and 6 weeks
Proportion of Responders (≥30% Decrease in Total Positive and Negative Syndrome Scale [PANSS])
Time Frame: Baseline and 6 weeks
Responders are subjects with 30% or more reduction from baseline in total PANSS score. PANSS is a medical scale that assesses various symptoms of schizophrenia. The symptoms are rated on a 7-point scale from 1 (absent) to 7 (extreme psychopathology). The total score is the sum of all 30 PANSS items, with a range of 30 (absent) to 210 (extreme ill).
Baseline and 6 weeks
Change From Baseline in Clinical Global Impression Scale (CGI-S)
Time Frame: Baseline and 6 weeks
The CGI-S rating scale is a 7-point global assessment with scores as follows: 1 - Not ill, 2 - Very Mild, 3 - Mild, 4 - Moderate, 5 - Marked, 6 - Severe, and 7 - Extremely Severe.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
