NCI Drug Dictionary


A human-mouse chimeric antibody, constructed from a murine antiinterleukin 6 (IL-6) monoclonal antibody, with antitumor and antiinflammatory activities. Containing the antigen-binding variable region of the murine antibody, CLB-IL-6-8, and the constant region of a human IgG1kappa immunoglobulin, siltuximab 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 antiinflammatory activities. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
