Pronunciation
Definition 1
A drug used to treat melanoma that has spread to other parts of the body or that cannot be removed by surgery. It is also being studied in the treatment of other types of cancer. Ipilimumab binds to a substance called CTLA-4, which is found on the surface of T cells (a type of white blood cell). Ipilimumab may block CTLA-4 and help the immune system kill cancer cells. It is a type of monoclonal antibody. Also called MDX-010 and Yervoy. (NCI Dictionary)
Definition 2
A fully human monoclonal antibody directed against cytotoxic T-lymphocyte-associated antigen-4 (CTLA4), an antigen that is expressed on activated T-cells and exhibits affinity for B7 co-stimulatory molecules. By binding CTLA4, ipilimumab enhances T-cell activation and blocks B7-1 and B7-2 T-cell co-stimulatory pathways. (NCI Thesaurus)
Definition 3
A monoclonal antibody being studied in the treatment of certain types of cancer. Ipilimumab is made in the laboratory and binds to the molecule CTLA-4 on T cells (a type of white blood cell). Ipilimumab may block CTLA-4 and help the immune system kill cancer cells. (NCI Dictionary)
