This document summarizes two phase 3 clinical trials that compared the multiple sclerosis drugs ofatumumab and teriflunomide. Ofatumumab is a subcutaneous anti-CD20 monoclonal antibody that selectively depletes B cells, while teriflunomide is an oral drug that reduces T-cell and B-cell activation. Across both trials, 946 patients were assigned to receive ofatumumab and 936 were assigned to receive teriflunomide, with a median follow-up of 1.6 years. The studies found that the annual relapse rate was significantly lower for patients taking ofatumumab compared to teriflunomide, and ofatumumab was also superior in suppressing lesion activity on MRI scans

- 2. Ofatumumab, a subcutaneous anti-CD20 monoclonal antibody, selectively depletes B cells. Teriflunomide, an oral inhibitor of pyrimidine synthesis, reduces T-cell and B-cell activation. The relative effects of these two drugs in patients with multiple sclerosis are not known METHODS In two double-blind, double-dummy, phase 3 trials, we randomly assigned patients with relapsing multiple sclerosis to receive subcutaneous ofatumumab or oral teriflunomide Overall, 946 patients were assigned to receive ofatumumab and 936 to receive teriflunomide; the median follow-up was 1.6 year
- 5. DISCUSSION Annualised Relapse rate defined as the total number of relapses divided by the total person-day at risk of relapse multiplied by 365 In these two simultaneously conducted active controlled trials involving patients with relapsing multiple sclerosis, both ofatumumab and teriflunomide were associated with low relapse rates. The relapse rate was significantly lower with ofatumumab than with teriflunomide in each of the two trials Ofatumumab was also superior to teriflunomide in suppressing lesion activity on MRI Injection-related reactions were more frequent with ofatumumab
