ECTRIMS 2023 | Positive Phase II data of novel anti-CD40L antibody frexalimab in MS

Erik Wallstroem, MD, PhD, Global Head of Development, Neurology and Opthalmology, Sanofi, and Tom Snow, VP, Global Franchise Head, Neurology and Rare Blood Disorders, Sanofi, discuss the emerging data on frexalimab for the treatment of multiple sclerosis (MS). The Phase II study offers promising results, showcasing a pronounced reduction in new active lesions by the 12-week mark. This reduction appeared even more pronounced with a higher dose at the 24-week point. The CD40 ligand inhibitor is unique in that it operates upstream in the immune system, disrupting interactions between T- and B-cells, and also has implications in the innate immune system. Given its novel mechanism and compelling early results, it has sparked significant interest and discussions among experts. This interview took place at the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) Congress 2023 in Milan, Italy.
