NCIt synonyms : Immunoglobulin G1, Anti-(Human Protein TEM1 (Tumor Endothelial Marker 1)) (Human-Mouse
Monoclonal MORAb-004 Heavy Chain), Disulfide with Human-Mouse Monoclonal MORAb-004
kappa-chain, Dimer; Anti-Endosialin Monoclonal Antibody MORAb-004;
NCIt definition : A humanized IgG1 monoclonal antibody directed against human endosialin/TEM1 (tumor
endothelial marker;CD248) with potential anti-angiogenic and antineoplastic activities.
Ontuxizumab binds to and inhibits the activity of cell surface protein endosialin/TEM1,
which may result in the inhibition of angiogenesis, tumor cell proliferation and metastasis.
Endosialin/TEM1 plays a key role in angiogenesis and may be overexpressed on tumor
stromal cells and endothelial cells.;
