About this study

Official title: A Randomized, Double-blind, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy and Safety of Two Dosages of Paliperidone ER in the Treatment of Patients With Schizoaffective Disorder.

The purpose of this study is to measure the effectiveness and assess the safety of two dosages of the antipsychotic paliperidone extended-release (ER) in patients who are experiencing an acute episode of schizoaffective disorder.

Read the detailed description

Schizophrenia and schizoaffective disorder are closely related in terms of symptoms, coexisting conditions, and genetic risk. In previous studies in patients with schizophrenia, treatment with paliperidone extended-release (ER) improved psychotic symptoms, as well as mood symptoms evaluated by anxiety/depression and hostility/excitement Positive and Negative Symptoms of Schizophrenia (PANSS) factor scores. Therefore, paliperidone ER may also be effective in treating symptoms of schizoaffective disorder. Paliperidone's limited potential for drug-drug interaction is particularly important in this patient population, in which multiple drug therapy is relatively common. This 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-controlled, parallel-group study is designed to examine the effectiveness and safety of paliperidone ER in adult patients with schizoaffective disorder who are experiencing an acute episode of this disorder. Patients in the study will be randomly assigned to 1 of 3 groups to receive 6 weeks of oral treatment with 1 of 2 dosages of paliperidone ER or placebo. The primary efficacy outcome will be the change from baseline to Week 6, or the last post-randomization assessment during double-blind treatment (endpoint), in the PANSS total score. Safety will be assessed by monitoring adverse events, clinical laboratory testing, pregnancy testing, vital signs measurements, physical examination, administration of a 12-lead ECG, movement disorders side effect scales, and the InterSePT Scale for Suicidal Thinking. Patients may also choose to participate in a pharmacogenomic (DNA) analysis. The primary study hypotheses are that at least one of the two dosages of paliperidone ER is better than placebo on the change from baseline in the PANSS total score in acutely ill patients with schizoaffective disorder at the end of 6 weeks of treatment. Patients will receive study drug by mouth for a total of 43 days. Beginning on Day 1, patients will take either placebo or 1 of 2 doses of paliperidone: 6 mg/day (low randomized dosage) or 12 mg/day (high randomized dosage). During the first 2 weeks, dosages may be adjusted.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Baseline Positive and Negative Symptoms of Schizophrenia (PANSS) Total Score

    The PANSS is a 30-item scale (range 30-210) 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. Higher scores indicate worsening.

    Measured: Baseline

  2. The Change From Baseline to Week 6 or the Last Post-randomization Assessment During Double-blind Treatment in the Positive and Negative Symptoms of Schizophrenia (PANSS) Total Score.

    The PANSS is a 30-item scale (range 30-210) 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. Higher scores indicate worsening.

    Measured: Baseline to Week 6 Last Observation Carried Forward (LOCF) End Point

Secondary outcomes (12)
  1. Number of Participants With Response

    Response is defined as a 30% or more reduction from baseline in PANSS total score and a CGI-C score of <= 2. (CGI-C-SCA: Clinical Global Impression of Change for Schizoaffective Disorder). The PANSS is a 30-item scale (range 30-210) designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and poor impulse control. 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 subject.

    Positive Syndrome Scale (range 7-49): Sum of scores for items 1-7 in positive subscale: delusions, conceptual disorganization, hallucinatory behavior, excitement, grandiosity, suspiciousness/persecution, and hostility. Higher scores indicate worsening.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Paliperidone ER in people with Schizoaffective Disorder and Psychotic Disorder, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jul 2013. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 28 Jul 2009). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Baseline Positive and Negative Symptoms of Schizophrenia (PANSS) Total Score (time frame: Baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00397033, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jul 2013.
