New Phase 3 Data Presented at Psych Congress 2021 Showed TV-46000/mdc-IRM Significantly Prolonged Time to Impending Relapse Compared to Placebo in Patients with Schizophrenia
Teva Pharmaceuticals announced positive results from the Phase 3 RISE study evaluating TV-46000, a long-acting injectable risperidone formulation, aimed at treating schizophrenia. The study showed that TV-46000 significantly prolonged time to relapse and increased clinical stability compared to placebo. Among 544 randomized patients, relapse rates were dramatically lower, with only 9% at week 24 for TV-46000 users versus 28% for placebo. The safety profile was consistent with existing risperidone formulations, indicating potential enhancements in treatment options for patients suffering from this disorder.
- Significant reduction in relapse rates (overall: 9% vs placebo: 28%)
- Prolonged time to impending relapse by 3.5 to 5 times versus placebo
- Efficacy data supports potential for improved patient outcomes
- Safety profile consistent with other risperidone formulations
- None.

Efficacy and Safety of Subcutaneous Risperidone Injectable (TV-46000) in Patients With Schizophrenia: A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Relapse Prevention Study (RISE Study)
The Phase 3 RISE study was designed to compare TV-46000 q1m and TV-46000 q2m with placebo (1:1:1 ratio; stage 2) in patients with schizophrenia
Out of 1267 patients screened, 863 were enrolled and 544 were randomized. Time to impending relapse significantly favored TV-46000 (hazard ratio [
About TV46000-CNS-30072 (The RISE Study – The Risperidone Subcutaneous Extended-Release Study)
The RISE study was a multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy of risperidone extended-release injectable suspension for subcutaneous use as a treatment in patients (ages 13-65 years) with schizophrenia. 544 patients were randomized to receive a subcutaneous injection of TV-46000 once monthly (q1M), once every two months (q2M), or placebo in a 1:1:1 ratio. The primary endpoint was time to impending relapse.
