BISPECIFIC ANTIBODIES THAT BIND TO VEGF RECEPTORS

摘要

The present invention is directed to production of antigen-binding proteins that bind specifically to an extracellular domains of two different VEGF receptors. The bispecific antigen-binding proteins block activation of the VEGF receptors and are used to reduce or inhibit VEGF-induced cellular functions such as mitogenesis of vascular endothelial cells and migration of leukemia cells. The antigen-binding proteins of the present invention can be monovalent or multivalent, have antigen-binding sites consisting of immunoglobulin heavy chain and light chain variable domains and may further include immunoglobulin constant domains.
