NCIt definition : A humanized agonistic monoclonal antibody directed against human tumor necrosis factor-related
apoptosis-inducing ligand receptor 2 (TRAIL-R2) with potential antitumor activity.
Mimicking the natural receptor ligand TRAIL, tigatuzumab binds to TRAIL-R2, activating
signal transduction pathways that may result in tumor cell apoptosis and a reduction
in tumor growth. A member of the tumor necrosis factor (TNF) receptor family, TRAIL-R2,
also known as DR5 (death receptor 5), is expressed on the surfaces of many types of
malignant cells.;
