The purpose of this study is to determine if risperidone is effective and safe in the prevention of mood episodes in patients with bipolar 1 disorder.

Clinical Details

Official title: A Randomized, Double-blind, Placebo-controlled Study to Explore the Efficacy and Safety of Risperidone Long-acting Intramuscular Injectable in the Prevention of Mood Episodes in Bipolar 1 Disorder, With Open-label Extension

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Prevention

Primary outcome: Number of Participants Who Had a Mood Relapse.

Secondary outcome:

Change in Young Mania Rating Scale (YMRS) Scores.

Change in Montgomery-├ůsberg Depression Rating Scale (MADRS)

Detailed description: RISPERDAL CONSTA (risperidone long-acting injection) may provide substantial improvement, by reducing patient non-compliance, in the long-term treatment of bipolar I disorder. This is a randomized (patients are assigned different treatments based on chance), double-blind, (neither the patient nor the physician knows whether drug or placebo is being taken, or at what dosage) placebo-controlled study to explore the safety and effectiveness of RISPERDAL CONSTA in the prevention of mood episodes in patients with bipolar 1 disorder. This study includes 5 periods: a screening period lasting up to 1 week; an open-label RISPERDAL (oral risperidone) treatment period lasting 3 weeks; an open-label RISPERDAL CONSTA stabilization period lasting 26 weeks; a double-blind period lasting up to 24 months; and an open-label extension with RISPERDAL CONSTA lasting 8 weeks. Efficacy will be assessed using the Young Mania Rating Scale (YMRS), Montgomery-├ůsberg Depression Rating Scale (MADRS), Clinical

Global Impressions - Severity (CGI-S) scale, Medical Outcomes Study Short Form 36 (SF-36),

and the Personal and Social Performance (PSP) scale. Safety will be evaluated throughout the study and includes assessment of adverse events, clinical laboratory tests (including hematology, serum chemistry, blood glucose/lipid profile, prolactin, and urinalysis); electrocardiograms (ECGs), vital signs (pulse and blood pressure), physical examination, body mass index (BMI), and the Extrapyramidal Symptom Rating Scale (ESRS). Oral risperidone (flexible dosage) 1 to 6 mg/day for the first 3 weeks. Risperidone LAI i. m. injections (12. 5mg, 25 mg, 37. 5 mg, or 50 mg) given every 2 weeks for up to approximately 2. 6 years (only 6 months for patients receiving placebo during DB-period)


Minimum age: 18 Years. Maximum age: 65 Years. Gender(s): Both.
