NCIt definition : A human immunoglobulin G1 (IgG1) monoclonal antibody directed against the pro-inflammatory
cytokine interleukin-6 (IL-6), with potential immunomodulating and anti-inflammatory
activities. Upon administration, sirukumab targets, binds to and blocks the activity
of IL-6, which may inhibit the binding of IL-6 to its receptor interleukin-6 receptor
(IL-6R). This may inhibit the IL-6/IL-6R-mediated signal transduction pathway and
the associated inflammatory response.;
