Abstract
The present invention relates to a method for producing patient cancerous disease modifying antibodies using a novel paradigm of screening. By segregating the anti-cancer antibodies using cancer cell cytotoxicity as an end point, the process makes possible the production of anti-cancer antibodies for therapeutic and diagnostic purposes. The antibodies can be used in aid of staging and diagnosis of a cancer, and can be used to treat primary tumors and tumor metastases. The anti-cancer antibodies can be conjugated to toxins, enzymes, radioactive compounds, and hematogenous cells.
Claims20
The isolated monoclonal antibody produced by the hybridoma deposited with the IDAC as accession number 170505-01.
The isolated hybridoma cell line deposited with the IDAC as accession number 170505-01.
A method for initiating antibody induced cellular cytotoxicity of cancerous cells in a tissue sample selected from a human tumor comprising:
- providing a tissue sample from said human tumor;
- providing the isolated monoclonal antibody produced by the hybridoma deposited with the IDAC as accession number 170505-01, a humanized version thereof, a chimeric version thereof or an antigen binding fragment thereof;
- and
- contacting said isolated monoclonal antibody, said humanized version thereof, said chimeric version thereof or said antigen binding fragment thereof with said tissue sample;
- wherein binding of said isolated monoclonal antibody, said humanized version thereof, said chimeric version thereof or said antigen binding fragment thereof with said tissue sample induces cellular cytotoxicity.
A binding assay to determine a presence of cancerous cells in a tissue sample selected from a human tumor, which is specifically bound by the isolated monoclonal antibody produced by hybridoma cell line AR59A269.5 having IDAC Accession No. 170505-01, comprising:
- providing a tissue sample from said human tumor;
- providing the isolated monoclonal antibody produced by a hybridoma cell line AR59A269.5 having IDAC Accession No. 170505-01, a humanized version thereof, a chimeric version thereof, or an antigen binding fragment thereof, or at least one isolated monoclonal antibody or antigen binding fragment thereof that specifically binds to the same epitope or epitopes as those recognized by the isolated monoclonal antibody produced by a hybridoma cell line AR59A269.5 having IDAC Accession No. 170505-01;
- contacting said monoclonal antibody, a humanized version thereof, a chimeric version thereof or an antigen binding fragment thereof with said tissue sample;
- and
- determining binding thereof with said tissue sample;
- whereby the presence of said cancerous cells in said tissue sample is indicated.
A method of treating a human tumor in a mammal, wherein said human tumor expresses at least one epitope of an antigen which is specifically bound by the isolated monoclonal antibody produced by the hybridoma deposited with the IDAC as accession number 170505-01, a humanized version thereof, a chimeric version thereof, an antigen binding fragment thereof or at least one isolated monoclonal antibody or antigen binding fragment thereof that specifically binds to the same epitope or epitopes as those recognized by the isolated monoclonal antibody produced by a hybridoma cell line AR59A269.5 having IDAC Accession No. 170505-01, comprising administering to said mammal said monoclonal antibody or antigen binding fragment thereof in an amount effective to result in a reduction of said mammal's tumor burden.
A method of treating a human tumor susceptible to antibody induced cellular cytotoxicity in a mammal, wherein said human tumor expresses at least one epitope of an antigen which is specifically bound by the isolated monoclonal antibody produced by the hybridoma deposited with the IDAC as accession number 170505-01, a humanized version thereof, a chimeric version thereof, an antigen binding fragment thereof or at least one isolated monoclonal antibody or antigen binding fragment thereof that specifically binds to the same epitope or epitopes as those recognized by the isolated monoclonal antibody AR59A269.5 having IDAC Accession No. 170505-01, comprising administering to said mammal said monoclonal antibody or an antigen binding fragment thereof in an amount effective to result in a reduction of said mammal's tumor burden.
