Siltuximab
Pronunciation
Definition 1
A human-mouse chimeric antibody, constructed from a murine anti-interleukin 6 (IL-6) monoclonal antibody, with antitumor and anti-inflammatory activities. Containing the antigen-binding variable region of the murine antibody, CLB-IL-6-8, and the constant region of a human IgG1kappa immunoglobulin, anti-IL-6 chimeric monoclonal antibody has high affinity for recombinant as well as native IL-6 and inhibits the binding of IL-6 to the IL-6 receptor (IL-6R), resulting in the blockade of the IL-6/IL-6R/gp130 signal transduction pathway, and, subsequently, antitumor and anti-inflammatory activities. (NCI Thesaurus)
Definition 2
A chimeric (made from human and mouse proteins) monoclonal antibody being studied in the treatment of advanced kidney cancer and other types of cancer. Monoclonal antibodies are made in the laboratory and can locate and bind to substances in the body, including cancer cells. Anti-IL-6 chimeric monoclonal antibody works by blocking inflammation and tumor growth. (NCI Dictionary)
