NCI Drug Dictionary


tocilizumab 
A recombinant, humanized IgG1 monoclonal antibody directed against the interleukin-6 receptor (IL-6R) with immunosuppressant activity. Tocilizumab targets and binds to both the soluble form of IL-6R (sIL-6R) and the membrane-bound form (mIL-6R), thereby blocking the binding of IL-6 to its receptor. This prevents IL-6-mediated signaling. Il-6, a pro-inflammatory cytokine that plays an important role in the regulation of the immune response, is overproduced in autoimmune disorders and certain types of cancers. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
