About this study
Official title: Risperidone Depot (Microspheres) in the Treatment of Subjects With Schizophrenia or Schizoaffective Disorder
The purpose of this study is to document the long-term safety and tolerability of risperidone, formulated as a long-acting injectable, in the treatment of patients with schizophrenia or schizoaffective disorder; in addition, to evaluate the long-term effectiveness of long-acting risperidone and its effect on quality of life
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 safety study is an extension of a randomized, double-blind, multicenter, parallel group study that investigates effectiveness and safety of risperidone injected intramuscularly in patients with schizophrenia or schizoaffective disorder. The present open-label study evaluates 3 different doses of a formulation of risperidone injected into the muscle at 2 week intervals for at least 1 year in patients with these conditions. Assessments of effectiveness include the Clinical Global Impression (CGI) overall severity of illness scale. Quality of life will be assessed by the SF-36 Health Survey. Safety evaluations include incidence of adverse events, physical examinations, and evaluations of the injection site, clinical laboratory tests, electrocardiograms (ECGs), and Extrapyramidal Symptom Rating Scale (ESRS), a scale assessing muscle tone, gain, and abnormal movements. Injections every 2 weeks for at least 1 year, beginning at 25milligrams[mg] and increasing to 50mg or 75mg (maximum dose). Dosages may be increased or decreased at investigator's discretion. During the first 3 weeks, risperidone tablets (2mg) once daily to supplement injectable risperidone.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Risperidone in people with Schizophrenia, 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 19 Nov 2010. 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?
Incidence of adverse events; Injection site evaluation; Extrapyramidal Sympton Rating Scale (ESRS) results at each visit for at least 1 year; Clinical evaluations (physical exams, laboratory tests) will be conducted throughout trial. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 19 Nov 2010.
