About this study
Official title: Treatment Success in Patients Requiring Treatment Change From Olanzapine to Risperidone Long Acting Injectable (TRESOR)
The purpose of the study is to evaluate the maintained effectiveness of long-acting injectable risperidone (RISPERDAL® CONSTA™) compared with the previous treatment with oral olanzapine in non-acute subjects with schizophrenia or schizoaffective disorder considered in need of a therapy change.
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. In addition, transitioning to a different antipsychotic drug is at times a necessary step in the clinical management of patients with schizophrenia due to different reasons, including insufficient response and poor tolerability. This is an open-label, non-randomized study of a formulation of risperidone (RISPERDAL® CONSTA™) (coated microspheres) injected into the muscle at week intervals over 6 months in patients with schizophrenia or schizoaffective disorder. During the first 3 weeks, oral olanzapine treatment is continued to provide therapy until the risperidone long-acting injectable reaches effective drug levels. The oral olanzapine treatment is tapered off within 1 week for one group of patients and within 3 weeks for another group. Assessments of effectiveness include the Positive and Negative Syndrome Scale (PANSS), overall severity of illness measured by the Clinical Global Impression (CGI) scale, and quality of life evaluated by the SF-36 questionnaire. Safety evaluations include incidence of adverse events through out the study and Extrapyramidal Symptom Rating Scale (ESRS), clinical laboratory tests (biochemistry, hematology, and urinalysis), and physical exams, including body weight, at specified intervals. The study hypothesis is that changing to treatment every 2 weeks with long-acting risperidone will provide a maintained effectiveness patients with schizophrenia or schizoaffective disorder and will be generally well-tolerated Risperidone, long-acting formulation for intramuscular injection (25 milligrams[mg]) every 2 weeks for 6 months. Investigator may adjust dosage to 37.5mg or 50mg (maximum) or supplement risperidone injections with risperidone tablets (2mg maximum), according to symptoms and treatment response.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing risperidone in people with Schizophrenia and Psychotic Disorders, run by Janssen Pharmaceutica N.V., Belgium.
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 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 7 Dec 2012. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 from baseline in total Positive and Negative Syndrome Scale (PANSS) score at the end of the treatment period (6 months).. 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 NCT00216632, 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 7 Dec 2012; AzTrials last refreshed its copy on 8 Nov 2026.
