The results of the first randomized, placebo-controlled trial of dimethyl fumarate in a cohort of participants with radiologically isolated syndrome showed efficacy against the risk of a first clinical demyelinating event. The findings pave the way for preventive medicine in multiple sclerosis and highlight the need for more precise prognostication of risk.
