Methods of treating diseases with anti-VEGF antibodies
The present invention provides monoclonal antibodies, and portions thereof, which are capable of specifically binding to human vascular endothelial cell growth factor (hVEGF) or hVEGF-related protein. The invention also provides hybridoma cell lines that produce such monoclonal antibodies. The monoclonal antibodies of the invention are useful as therapeutic agents, either by themselves or in conjunction with cytotoxic or other chemotherapeutic agents, to treat diseases that are characterized by excessive vascular endothelial cell proliferation. The monoclonal antibodies of the invention also are useful in diagnostic and analytical methods for determining the presence of hVEGF or hVEGF related-protein in a test sample.
1. A method of treating diseases that are characterized by excessive vascular endothelial cell proliferation comprising administering a monoclonal antibody to human vascular endothelial growth factor (hVEGF), wherein said monoclonal antibody to hVEGF binds to the same hVEGF epitope as monoclonal antibody A4.6.1 (ATCC HB 10709).
2. The method of claim 1 , wherein the monoclonal antibody to hVEGF inhibits binding of A4.6.1 (ATCC HB 10709) to hVEGF in a competitive binding ELISA.
3. The method of claim 1 , wherein the monoclonal antibody to hVEGF is used as a single agent.
4. The method of claim 1 , wherein the monoclonal antibody to hVEGF is used in conjunction with another cytotoxic agent.
5. The method of claim 1 , wherein the monoclonal antibody to hVEGF is used in conjunction with another chemotherapeutic agent.
6. The method of claim 1 , wherein the monoclonal antibody to hVEGF is administered serially or in combination with a radiological treatment.
