Antibodies directed to angiopoietin-2 and uses thereof
Antibodies directed to the antigen Ang-2 and uses of such antibodies are described. In particular, fully human monoclonal antibodies directed to the antigen Ang-2. Nucleotide sequences encoding, and amino acid sequences comprising, heavy and light chain immunoglobulin molecules, particularly sequences corresponding to contiguous heavy and light chain sequences spanning the framework regions and/or complementarity determining regions (CDR's), specifically from FR1 through FR4 or CDR1 through CDR3. Hybridomas or other cell lines expressing such immunoglobulin molecules and monoclonal antibodies.
1. A method of treating Angiopoietin-2 induced angiogenesis, comprising administering to an animal in need thereof a therapeutically effective dose of a monoclonal antibody that binds Angiopoietin-2 (Ang-2), wherein the animal in need suffers from an angiogenesis-related disease, and wherein the antibody is selected from the group consisting of:
a) an antibody comprising the heavy chain CDR1, CDR2 and CDR3 of SEQ ID NO:79, and the light chain CDR1, CDR2 and CDR3 of SEQ ID NO: 81; and
b) an antibody comprising a variable heavy chain sequence with 90% identity to SEQ ID NO:79 and a variable light chain sequence with 90% identity to SEQ ID NO:81,
wherein angiogenesis is inhibited.
2. The method of claim 1 , wherein said animal is human.
3. The method of claim 1 , wherein said monoclonal antibody is antibody 3.19.3 (ATCC Accession Number PTA-7260).
4. The method of claim 1 , wherein the monoclonal antibody is provided in association with a pharmaceutically acceptable carrier.
