ofatumumab
(OH-fa-TOO-moo-mab)
A drug used alone or with other anticancer drugs to treat certain types of chronic lymphocytic leukemia (CLL). It is also being studied in the treatment of other types of cancer. Ofatumumab binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of leukemia and lymphoma cells. Ofatumumab may block CD20 and help the immune system kill cancer cells. It is a type of monoclonal antibody. Also called Arzerra and HuMax-CD20.
