HOW Kesimpta® WORKS
Kesimpta®, a monoclonal antibody, binds to a protein on the surface of immune cells, white blood cells called B lymphocytes or B cells. This depletes B cells, preventing them from stripping the myelin sheath and causing nerve damage.
FDA-Approved
Kesimpta® was FDA-approved in 2020 to treat relapsing forms of MS, including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.
Potential Side Effects
Upper respiratory tract infection (URTI), including sore throat, runny nose, and headache, as well as headache unrelated to a URTI. Serious but less-common adverse events include infections, hepatitis B virus (HBV) reactivation, and a weakened immune system. A possible serious side effect is progressive multifocal leukoencephalopathy (PML), a rare brain infection that usually leads to death or severe disability over a period of weeks or months.
