NCIt definition : A human monoclonal antibody directed against Delta-like ligand-4 (DLL4) with potential
antineoplastic activity. Enoticumab specifically binds to human DLL4, preventing its
binding to Notch receptors and inhibiting Notch signaling, which may result in defective
tumor vascularization and, so, the inhibition of tumor cell growth. DLL4 is the only
Notch ligand selectively expressed on endothelial cells; DLL4/Notch signaling is required
for the development of functional tumor blood vessels.;
