How much does Natalizumab cost?

Natalizumab is a recombinant integrin monoclonal antibody that blocks the activity of VLA4 integrin and prevents activated T lymphocytes from passing through the blood-brain barrier, thereby reducing the inflammatory response of the central nervous system, thereby reducing inflammation and damage. Natalizumab is mainly used to treat relapsing and progressive stages of multiple sclerosis. Natalizumab is usually given as an intravenous injection every 4 weeks. Natalizumab’s patent medicine is not on the domestic market and cannot be included in medical insurance. Currently, the generic drug natalizumab on the market overseas may cost more than 8,000 US dollars per box (the price may fluctuate due to exchange rates), which is very expensive.
