Estimating the term…
This invention relates to the use of monoclonal and polyclonal antibodies that specifically bind to and have the ability in the alternative to become internalized by cells expressing endosialin and to induce an immune effector activity such as antibody-dependent cellular cytotoxicity. The antibodies are useful in specific delivery of pharmacologic agents to endosialin-expressing cells as well as in eliciting an immune-effector activity particularly on tumor and neovascular cells and precursors. The invention is also related to nucleotides encoding the antibodies of the invention, cells expressing the antibodies; methods of detecting cancer and neovascular cells; and methods of treating cancer and neovascular disease using the antibodies, derivatives and fragments.
A method of inhibiting growth of endosialin-positive cells comprising administering to a subject having said cells a therapeutically effective amount of a humanized antibody that specifically binds to endosialin, or antigen-binding fragment thereof, comprising the variable domains of the antibody produced by the cells assigned ATCC accession no. PTA-7554, wherein said antibody or antigen-binding fragment is conjugated to a cytotoxic biomolecule or to a chemotherapeutic agent.
A method of treating colorectal cancer characterized by endosialin expression in a subject in need thereof, said method comprising administering to said subject a therapeutically effective amount of a humanized antibody that specifically binds to endosialin, or antigen-binding fragment thereof, comprising the variable domains of the antibody produced by the cells assigned ATCC accession no. PTA-7554, wherein said antibody or antigen-binding fragment is conjugated to a cytotoxic biomolecule or to a chemotherapeutic agent.
A method of inhibiting growth of endosialin-positive cells comprising administering to a subject having said cells a therapeutically effective amount of a humanized antibody that specifically binds to endosialin, or antigen-binding fragment thereof, comprising the variable domains of the antibody produced by the cells assigned ATCC accession no. PTA-7554, wherein said antibody or antigen-binding fragment comprises a portion of an immunoglobulin constant region (Fc) capable of eliciting complement dependent cytotoxic activity or antibody-dependent cellular cytotoxicity.
A method of treating colorectal cancer characterized by endosialin expression in a subject in need thereof, said method comprising administering to said subject a therapeutically effective amount of a humanized antibody that specifically binds to endosialin, o antigen-binding fragment thereof, comprising the variable domains of the antibody produced by the cells assigned ATCC accession no. PTA-7554, wherein said antibody or antigen-binding fragment comprises a portion of an immunoglobulin constant region (Fc) capable of eliciting complement dependent cytotoxic activity or antibody-dependent cellular cytotoxicity.
