About this study
Official title: An Open Label, Long Term Trial of Risperidone Long Acting Microspheres in the Treatment of Patients Diagnosed With Schizophrenia
The purpose of this study is to document the long term safety of a long-acting injectable formulation of risperidone in the treatment of patients with schizophrenia who have previously been treated with long-acting risperidone. Efficacy will also be evaluated.
Read the detailed description
This is an open-label, long-term study of a flexible dose of a long-acting injectable formulation of risperidone (risperidone LAI) injected into the muscle at 2 week intervals for at least 12 months in patients diagnosed with schizophrenia. It is an extension of an open label study of patients with schizophrenia (RIS-USA-259) switching from treatment with an oral antipsychotic medication to long-acting injectable risperidone. Safety evaluations include incidence of adverse events, physical examinations, clinical laboratory tests (biochemistry, hematology, and urinalysis), electrocardiograms (ECGs), and Extrapyramidal Symptom Rating Scale (ESRS), a scale for assessing muscle tone, gait, and abnormal movements. Efficacy assessments include measurements using the Positive and Negative Syndrome Scale for Schizophrenia (PANSS) and the Clinical Global Impression-Severity of Illness scale (CGI-S). Risperidone (25-50milligrams [mg]) injections, long-acting formulation, every 2 weeks for at least 1 year. Dosages may be increased (50 mgs maximum) or decreased at discretion of the investigator. Supplementary risperidone tablets (1mg) may be administered.

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 1 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 8 Jun 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?
To accumulate long-term safety data: incidence of adverse events and clinical evaluations (physical examination, Extrapyramidal Symptom Rating Scale [ESRS], laboratory tests, ECGs).. 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 8 Jun 2011; AzTrials last refreshed its copy on 2 Nov 2026.
