Terms & Properties

Preferred Name: Etaracizumab

Definition: A humanized monoclonal IgG1 antibody directed against the vitronectin receptor alpha v beta 3 integrin. Etaracizumab blocks the binding of ligands, such as vitronectin, to alpha v beta 3 integrin, resulting in inhibition of angiogenesis and metastasis. Alpha v beta 3 integrin is a cell adhesion and signaling receptor that is expressed on the surface of tumor vessel endothelial cells, some tumor cells, and a number of other cell types.

NCI-GLOSS Definition: A substance being studied in the treatment of some types of cancer and other conditions. Abegrin binds to a protein on the surface of blood vessels and may prevent the growth of new blood vessels that tumors need to grow. It may also prevent the spread of cancer.
