About this study

Official title: The Efficacy And Safety Of Flexible Dosage Ranges Of Risperidone Versus Placebo In The Treatment Of Manic Episodes Associated With Bipolar I Disorder.

The purpose of the study is to assess the effectiveness and safety of risperidone (an antipsychotic medication) versus placebo during 3 weeks of treatment of mania in patients with Bipolar I Disorder who are suffering a manic episode.

Read the detailed description

Antipsychotic agents have, for a long time, been used to alleviate the severe behavioral problems associated with manic episodes. Risperidone, widely used in the treatment of schizophrenia, has been shown to be effective in the treatment of manic and mixed episodes associated with bipolar disorders. This is a randomized, double-blind, placebo-controlled study to evaluate the effectiveness and safety of risperidone compared with placebo in the treatment of patients with bipolar disorder who are experiencing a manic episode. Patients receive study medication (risperidone or placebo tablets) to be taken orally once a day at gradually increasing doses during the first week to achieve optimal effectiveness, while minimizing any intolerance to the drug. By Day 4, the dose of risperidone is in the range of 1 to 6 mg/day, and treatment with risperidone or placebo tablets continues for 3 weeks. The primary measure of effectiveness is the change in the Young Mania Rating Scale (YMRS) total score from baseline to the end of treatment. Additional assessments of effectiveness include the Clinical Global Impression-Severity of Illness (CGI-S) scale; the Global Assessment Scale (GAS), which assesses the patient's level of functioning; and the Positive and Negative Syndrome Scale (PANSS), a scale for measuring psychotic symptoms. Safety assessments include the incidence of adverse events throughout the study; measurement of vital signs (temperature, pulse, blood pressure) and evaluation of the presence and severity of extrapyramidal symptoms by the Extrapyramidal Symptom Rating Scale (ESRS) at specified intervals; and clinical laboratory tests (hematology, biochemistry, urinalysis) at the start and end of the study. The study hypothesis is that daily treatment with risperidone is more effective than placebo, as measured by Young Mania Rating Scale scores, in the treatment of the manic phase of Bipolar I Disorder. Risperidone tablets,1 mg (or placebo tablets) taken orally once daily in the evening; dose of 3 mg on Day 1; dose range of 2 - 4 mg on Day 2; dose range 1 - 5 mg on Day 3; dose range 1 - 6 mg on Days 4 - 21. Doses may be increased or decreased at investigator's discretion.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Risperidone, oral tablets in people with Bipolar Disorders and Manic Episode, 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 4 inclusion and 5 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 14 Jan 2011. 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. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change in Young Mania Rating Scale (YMRS) total score from baseline to the end of treatment.. 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 NCT00257075, which also lists 1 linked publication.

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 14 Jan 2011.
