What Arzerra is and what it is used for
Arzerra contains ofatumumab, which belongs to a group of medicines called monoclonal antibodies.
Arzerra is used to treat chronic lymphocytic leukemia (CLL). CLL is a cancer of the blood that affects a type of white blood cell called lymphocytes. Lymphocytes multiply very quickly and live too long, so too many of them circulate in your blood. The disease may also affect other organs in your body. The antibody in Arzerra recognizes a substance on the surface of lymphocytes and causes them to die.
Arzerra is used to treat CLL in patients who have not responded to other types of chemotherapy or other treatments.
