Tysabri is approved by the U.S. Food and Drug Administration (FDA) as a monotherapy (not to be used in combination with other disease-modifying therapies) for the treatment of relapsing forms of multiple sclerosis, which include clinically isolated syndrome, relapsing-remitting disease (RRMS) and active secondary progressive disease (SPMS with relapses).
