This photo provided by Genentech shows the company’s drug Ocrevus. Late Tuesday, March 28, 2017, the Food and Drug Administration approved Ocrevus, the first drug for an aggressive kind of multiple sclerosis that steadily reduces coordination and the ability to walk. While there are more than a dozen treatments for the most common form of MS, there’s been nothing specifically for people with the type called primary progressive MS. That type of MS is relatively rare, affecting about 50,000 Americans. Ocrevus was also approved for relapsing forms of MS, which progress more slowly.
