JAMA Neurology 10.1001/jamaneurol.2026.0007February 16, 2026 at 11:00 AM EST
What is the long-term clinical efficacy and safety of ublituximab in people with relapsing multiple sclerosis (RMS)?In this trial including 985 adults, participants treated with continuous ublituximab for up to 5 years in the open-label extension study after completion of the randomized Study to Assess the Efficacy and Safety of Ublituximab in Participants With Relapsing Forms of Multiple Sclerosis (ULTIMATE) had significantly lower annualized relapse rate and confirmed disability progression than those initially treated with teriflunomide. The overall safety profile of ublituximab remained consistent with no new safety signals emerging with prolonged treatment.Results suggest that early initiation of ublituximab and continued treatment over a period of 5 years provided sustained clinical benefits in participants with RMS.
