About this study
Official title: A Parallel-Group Comparative Open-Label Study of Long-Acting Injectible Risperidone Versus Risperidone Tablets in Patients With Schizophrenia.
The purpose of this study is to evaluate the effectiveness and safety of risperidone, formulated as a long-acting injectable drug, compared with risperidone tablets in the treatment of patients with schizophrenia.
Read the detailed description
Although many schizophrenia patients currently take oral antipsychotic medications, it is estimated that up to 75% of them have difficulty adhering to the daily oral regimen. Long-acting injectable formulations may eliminate the need for daily medication and enhance patient compliance with the treatment regimen. This is an open-label, randomized, Phase III trial in patients with schizophrenia. One treatment group receives 25 to 50 mgs of long-acting risperidone, formulated for intramuscular injections, at study initiation and again after 2 weeks, while phasing out any previous antipsychotic medication during the initial 3 weeks of the study. Continuing in the treatment phase, long-acting injections are administered once every 2 weeks through Week 24, and post-treatment observation is performed for 6 weeks (total study duration of 30 weeks). Patients in the other treatment group take oral risperidone tablets, 2 to 6 mgs daily, from study initiation for 24 weeks. Post-treatment observation continues for 1 week for this group (total study duration of 25 weeks). Assessments of effectiveness made at specified intervals during treatment include Positive And Negative Syndrome Scale (PANSS), a scale for the measurement of symptoms of schizophrenia; Clinical Global Impression - Severity (CGI-S), a measure of overall severity of illness, and Clinical Global Impression - Changes (CGI-C); as well as, Brief Psychiatric Rating Scale (BPRS). Safety evaluations include the incidence of adverse events throughout the study; inspection of the injection site at times of treatment; Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS), vital signs (pulse, blood pressure, temperature), and laboratory tests (hematology, biochemistry, urinalysis) at monthly intervals. The study hypothesis is that treatment with long-acting risperidone injections is not inferior to oral risperidone, as measured by changes in PANSS total score from baseline through endpoint (24 weeks), in patients with schizophrenia and is generally well-tolerated. Risperidone, long-acting formulation for intramuscular injections (25 milligrams[mg] to 50mg, maximum), given biweekly through 24 weeks. Oral risperidone (2mg/day to 6mg/day [maximum]) administered daily for 24 weeks.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing risperidone in people with Schizophrenia, run by Janssen Pharmaceutical K.K..
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 4 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 17 May 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?
Positive and Negative Syndrome Scale (PANSS) at screening, Weeks 8, 16, and 24.. 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 NCT00240708, 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 17 May 2011.
