Natalizumab, sold under the brand name Tysabri among others, is a medication used to treat multiple sclerosis (MS) and Crohn's disease (CD).[3] For MS it is used for clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.[3] For CD it is used when other treatments are not effective.[3] It is given by gradual injection into a vein every 4 weeks.[4]
Common side effects include urinary tract infection, throat inflammation, headache, dizziness, nausea, joint pain and tiredness.[4] Other side effects may include progressive multifocal leukoencephalopathy (PML), herpes encephalitis, liver problems, anaphylaxis, low platelets, and infection.[3] It is a monoclonal antibody which attaches to a protein called α4β1 integrin on white blood cells, decreasing inflammation.[4]
Natalizumab was approved for medical use in the United States in 2004 and Europe in 2006.[5][4] In the United Kingdom it costs the NHS about £1,100 per dose as of 2021.[6] In the United States this amount costs about 7,800 USD.[7]
