A Study of Long-acting Injectable Risperidone in the Treatment of Patients With Schizophrenia or Schizoaffective Disorder
November 18, 2010 updated by: Johnson & Johnson Pharmaceutical Research & Development, L.L.C.
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
Study Overview
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.
