FDA approval of Vumerity (diroximel fumarate), a new therapy for people with multiple sclerosis (MS) offering improved gastrointestinal tolerability over Tecfidera (dimethyl fumarate), marks a win for its co-developers, Biogen Inc. and Alkermes plc, while triggering a $150 million payment from Biogen to its partner to mark the milestone. Biogen will also pay Alkermes a royalty on worldwide sales of the product.
