FDA Approves Ocrevus. South San Francisco, CA -- March 28, 2017 -- Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that the U.S. Food and Drug Administration (FDA) approved Ocrevus (ocrelizumab) as the first and only medicine for both relapsing and primary progressive forms of multiple sclerosis.
Roche (OTCQX:RHHBY) now has the first approved drug for both the relapsing and primary progressive forms of multiple sclerosis in the shape of Ocrevus. But the company is not taking any chances on price â at $65,000 it will cost less than existing MS therapies, giving the Swiss firm a good shot at penetrating the $20bn market. Also in Ocrevusâ favor is its label, which has no black box warning or risk-mitigation requirements, unlike some other MS treatments.
