Kesimpta is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to treat relapsing forms of multiple sclerosis in adults. Kesimpta is also referred to by its drug name, ofatumumab.

Kesimpta is a biologic immunomodulator, a drug that changes the immune system. Kesimpta is a CD20-directed cytolytic antibody (a protein used by the immune system to identify and neutralize substances). Kesimpta is believed to work by reducing the number of CD20-positive B cells, a type of immune system cell involved in relapsing multiple sclerosis.
