NCIt definition : A humanized, Fc disabled anti-human glucocorticoid-induced tumor necrosis factor receptor
(GITR) monoclonal antibody (MoAb) with immunomodulating activity. Anti-human GITR
MoAb TRX518 blocks the interaction of GITR, found on multiple types of T cells, with
its ligand, thereby inducing both the activation of tumor-antigen-specific T effector
cells, as well as abrogating the suppression induced by inappropriately activated
T regulatory cells. This agent is shown to act synergistically with chemotherapeutic
drugs in multiple cancer models.;
