The new drug, called Ocrevus, is sold by the company Genentech and can be given through an intravenous infusion by a health professional. On Tuesday, the U.S. Food and Drug Administration (FDA) approved Ocrevus to treat primary progressive multiple sclerosis (PPMS) as well as more common relapsing forms of MS. Both diseases are characterized by cognitive decline and weakness. People with MS undergo periods of relapses and remissions, and the cycle can harm mental and physical function. An estimated 15% of people with MS will have PPMS, in which they have steady declines in function usually without relapses or remissions. In clinical trials, people with MS who took Ocrevus had lower relapse rates and less disability compared to people taking another drug for the disease. In a study of 732 people with PPMS, the drug slowed the men and women’s worsening symptoms better than a placebo. Though the drug does not halt disease progression for people with PPMS, it remains the first and only drug approved the condition. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4716684/fda-drug-approval-ms-multiple-sclerosis/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4716684/fda-drug-approval-ms-multiple-sclerosis/"},"headline":"FDA Approves First Drug for Severe Multiple Sclerosis","datePublished":"2017-03-29T17:23:09.000Z","dateModified":"2026-02-23T04:05:43.102Z","description":"The FDA approved a new drug called Ocrevus for people with multiple sclerosis.","url":"https://time.com/4716684/fda-drug-approval-ms-multiple-sclerosis/","keywords":["medicine","FDA"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd8ec5e1b7b3a2ec1/6988604d428a9ee183ccebe6/rx-prescription-bottle-health-illo.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alexandra Sifferlin","jobTitle":null,"url":"https://time.com/author/alexandra-sifferlin/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd8ec5e1b7b3a2ec1/6988604d428a9ee183ccebe6/rx-prescription-bottle-health-illo.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"TIME.com stock health rx prescription bottle drugs","caption":"TIME.com stock health rx prescription bottle drugs","creditText":"Illustration by Sydney Rae Hass for TIME","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/medicine/","name":"medicine"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4716684/fda-drug-approval-ms-multiple-sclerosis/","name":"FDA Approves First Drug for Severe Multiple Sclerosis"}}]}] ```
