A New England Journal of Medicine study finds frexalimab, an anti-CD40L monoclonal antibody, significantly reduces disease activity in relapsing multiple sclerosis patients in a Phase II trial.

A study published in the New England Journal of Medicine has found that frexalimab, an anti-CD40L monoclonal antibody, has a favorable effect on relapsing multiple sclerosis. The Phase II, double-blind trial examined frexalimab treatment for relapsing multiple sclerosis, with patients receiving either 1,200 mg of frexalimab administered intravenously every four weeks, 300 mg frexalimab administered subcutaneously every two weeks, or placebos. The adjusted mean number of new gadolinium-enhancing T1-weighted lesions was 0.2 and 0.3 in the groups that received 1,200 and 300 mg frexalimab, respectively, indicating a significant reduction in disease activity.
