A pegylated, cross-linked, humanized divalent-Fab’ antibody fragment directed against vascular endothelial growth factor receptor-2 (VEGFR-2) with potential antiangiogenic and antitumor activities. Pegylated anti-GFR antibody fragment binds to and inhibits VEGFR-2, which may inhibit angiogenesis and tumor cell proliferation. Multivalent Fab’ antibody fragments may exhibit improved retention and internalization properties compared to their parent IgGs. Check for active clinical trials using this agent. (NCI Thesaurus)
