Tysabri® is a laboratory-produced monoclonal antibody. It is designed to hamper movement of potentially damaging immune cells from the bloodstream, across the “blood-brain barrier” into the brain and spinal cord.
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) to treat relapsing forms of MS.
