Diroximel fumarate (Vumerity®), an
orally administered disease-modifying drug (DMD), expands the available treatment
options for adults with relapsing forms of multiple sclerosis (MS), including
clinically isolated syndrome, relapsing-remitting MS (RRMS), and active
secondary progressive MS. It demonstrates bioequivalence to dimethyl fumarate
and was developed to provide similar clinical benefits, but with an improved
gastrointestinal (GI) tolerability profile. In RRMS patients who are
treatment-naïve or were previously treated with interferon-β or glatiramer
acetate, diroximel fumarate reduces annualized relapse rates, with most
patients experiencing no relapses during treatment, and reduces the formation
of new MS-associated brain lesions. Diroximel fumarate has an acceptable
tolerability profile that is consistent with that of dimethyl fumarate, albeit
with a significantly lower rate of GI adverse events.
