Sanofi has announced that its experimental drug, tolebrutinib, has demonstrated a significant 31% delay in the progression of disability for patients with non-relapsing secondary progressive multiple sclerosis (nrSPMS) in a phase 3 trial. This development provides hope for patients suffering from this progressive form of multiple sclerosis, for which there is currently no effective treatment. The French pharmaceutical company plans to file for approval of tolebrutinib later this year. Despite the promising results, the drug showed higher new Gd-enhancing T1 lesions compared to teriflunomide in the GEMINI-1/2 trials. The results were presented at the ECTRIMS 2024 conference.
