Phase III Study Testing Remibrutinib Safety and Effectiveness for Treating Secondary Progressive Multiple Sclerosis in Adults 18 to 65

What this Trial Is About

Researchers are evaluating the efficacy and safety of remibrutinib in patients with secondary progressive multiple sclerosis SPMS. This is a Phase III, randomized, double-blind, placebo-controlled, multi-center study involving approximately 1275 participants. The study aims to provide important data on remibrutinibs effect on disability progression in SPMS and includes both a Core Part and an Extension Part for further assessment. Participants are randomly assigned to receive either remibrutinib or a matching placebo as oral film-coated tablets during the Core Part. The Core Part includes double-blind treatment, followed by an Extension Part where all participants receive open-label remibrutinib tablets. Treatment is taken orally, and the study is event-driven, continuing until required endpoints are met. During the study, participants undergo regular assessments of disability progression using the Expanded Disability Status Scale EDSS, Timed 25-Foot Walk, 9-Hole Peg Test, and Symbol Digit Modalities Test, among others. Brain imaging and safety monitoring for adverse events are performed throughout up to approximately five years. Researchers track changes in brain lesions and atrophy, and follow participants for safety and treatment effects over time.
