Treatment of cancer involving mutated KRAS or BRAF genes
The present invention provides a method of treating cancer in a subject wherein the cancer comprises mutated KRAS or BRAF genes. The method comprises administering to the subject an effective amount of an antibody or antigen binding fragment thereof wherein the antibody or antigen binding fragment thereof competes with SC104 for binding to the human colon cancer cell line Colo205.
1. A method of treating cancer in a subject wherein the cancer comprises mutated KRAS or BRAF genes, the method comprising administering to the subject an effective amount of an antibody or antigen binding fragment thereof comprising a light chain and heavy chain amino acid sequence combination selected from the group consisting of SEQ ID NO:7/SEQ ID NO:25, SEQ ID NO:7/SEQ ID NO:50, SEQ ID NO:7/SEQ ID NO:94, SEQ ID NO:8/SEQ ID NO:26 and SEQ ID NO:8/SEQ ID NO:38.
2. A method of treating cancer in a subject, the method comprising testing the cancer for the presence of mutated KRAS or BRAF genes and, if the cancer has a mutated KRAS or a mutated BRAF gene, administering to the subject an effective amount of an antibody or antigen binding fragment thereof comprising a light chain and heavy chain amino acid sequence combination selected from the group consisting of SEQ ID NO:7/SEQ ID NO:25, SEQ ID NO:7/SEQ ID NO:50, SEQ ID NO:7/SEQ ID NO:94, SEQ ID NO:8/SEQ ID NO:26 and SEQ ID NO:8/SEQ ID NO:38.
3. A method as claimed in claim 1 , wherein the cancer is selected from the group consisting of colon cancer, pancreatic cancer, and gastric cancer.
4. A method as claimed in claim 1 , wherein the antibody is a deimmunized.
5. A method as claimed in claim 1 , wherein the antibody or antigen binding fragment comprises SEQ ID NO:7 and SEQ ID NO:94.
6. The method as claimed in claim 1 , wherein the antibody or antigen binding fragment thereof has been glyco-engineered to enhance antibody-dependent cell-mediated cytotoxicity.
7. A method as claimed in claim 2 , wherein the cancer is selected from the group consisting of colon cancer, pancreatic cancer, and gastric cancer.
8. A method as claimed in claim 2 , wherein the antibody is a deimmunized.
9. A method as claimed in claim 2 , wherein the antibody or antigen binding fragment comprises SEQ ID NO:7 and SEQ ID NO:94.
10. The method as claimed in claim 2 , wherein the antibody or antigen binding fragment thereof has been glyco-engineered to enhance antibody-dependent cell-mediated cytotoxicity.
11. The method as claimed in claim 1 , wherein the antibody or antigen binding fragment thereof competes with SC104 for binding to the human colon cancer cell line Colo205.
12. The method as claimed in claim 2 , wherein the antibody or antigen binding fragment thereof competes with SC104 for binding to the human colon cancer cell line Colo205.
