Clinical Trial Summary

This is a Phase 3 extension, global, multicenter study to assess the long-term safety and tolerability of tolebrutinib in adult participants (aged ≥18 years) with RMS, PPMS, or NRSPMS who were previously enrolled in the Phase 2b LTS (LTS16004) or 1 of the 4 Phase 3 tolebrutinib pivotal trials (GEMINI 1 [EFC16033], GEMINI 2 [EFC16034], HERCULES [EFC16645], or PERSEUS [EFC16035]). SUBSTUDY: ToleDYNAMIC substudy


Clinical Trial Description

Participants with relapsing MS from the Phase 2b LTS16004 parent study will continue open-label (OL) tolebrutinib. All participants from the Phase 3 parent studies (EFC16033, EFC16034, EFC16645, and EFC16035) will learn which treatment they received in the parent study: - If from one of the Phase 3 relapsing MS studies and on teriflunomide, an accelerated elimination procedure or a 3-month washout period is required prior to starting OL tolebrutinib. If on teriflunomide, and benefiting and recommended by the Investigator, the participant may opt to continue teriflunomide outside of the LTS17043 study, if clinically appropriate. If on tolebrutinib, the participant will continue tolebrutinib. - All participants from one of the Phase 3 progressive MS studies will start OL tolebrutinib. - If a participant already started OL tolebrutinib in the Phase 3 parent study this will be continued. - RMS participants who are not eligible for OL tolebrutinib per Health Authority and/or ethics committee decisions on the study conduct (ie, partial hold on initiation of tolebrutinib) will continue their parent study treatment assignment as per their randomization from the parent study. The treatment duration per participant will be approximately 3 years of OL tolebrutinib. ;
