Roche's multiple sclerosis (MS) drug Ocrevus won U.S. approval, putting the potential blockbuster back on track after a brief delay and giving a lift to patients with a form of the disease that until now had no approved treatment.
The drug, also known as ocrelizumab and administered via infusion, becomes the first U.S. Food and Drug Administration-approved medicine for the primary progressive form of the neurological disease (PPMS).
