NCIt definition : An agonistic humanized monoclonal antibody that recognizes inducible T-cell co-stimulator
(ICOS; CD278), with potential antineoplastic activity. Upon administration, anti-ICOS
agonist monoclonal antibody JTX-2011 targets and binds to ICOS expressed on certain
T-cells. This stimulates ICOS-mediated signaling, induces proliferation of ICOS-positive
T-cells, enhances cytotoxic T-lymphocyte (CTL) survival and augments the CTL-mediated
immune response against tumor cells. ICOS, a T-cell specific, CD28-superfamily co-stimulatory
molecule and immune checkpoint protein, is normally expressed on certain activated
T-cells and plays a key role in the proliferation and activation of T-cells.;
