Detailed Description

The study CLOU064C12302 consists of an initial Core Part (CP) (maximum duration per participant of up to 30 months), followed by an Extension Part (EP, of up to 5 years duration) for eligible participants. The Core Part is a randomized, double-blind, double-dummy, active comparator-controlled, fixed-dose, parallel-group, multi-center study in approximately 800 participants with relapsing multiple sclerosis (RMS). The Extension Part is an open-label, single-arm, fixed-dose design in which eligible participants are treated with remibrutinib for up to 5 years. A second study of identical design (CLOU064C12301) will be conducted simultaneously. Both studies will be conducted globally and data from the two studies will be pooled for some of the endpoints.


Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
