Abstract

The present invention describes combination treatment comprising a PD-1 axis binding antagonist and a MEK inhibitor and methods for use thereof, including methods of treating conditions where enhanced immunogenicity is desired such as increasing tumor immunogenicity for the treatment of cancer.

First claim

What is claimed is:

1. A method for treating or delaying progression of colorectal cancer or melanoma in an individual comprising administering to the individual an effective amount of an anti-PD-1 antibody and a MEK inhibitor, wherein the MEK inhibitor is selected from the group consisting of G02442104, G-38963, G02443714, G00039805 and GDC-0973, or a pharmaceutically acceptable salt or solvate thereof.

2. The method of claim 1 , wherein the anti-PD-1 antibody inhibits the binding of PD-1 to its ligand binding partners.

3. The method of claim 2 , wherein the anti-PD-1 antibody inhibits the binding of PD-1 to PD-L1.

4. The method of claim 2 , wherein the anti-PD-1 antibody inhibits the binding of PD-1 to PD-L2.

5. The method of claim 2 wherein the anti-PD-1 antibody inhibits the binding of PD-1 to both PD-L1 and PD-L2.

6. The method of claim 1 , wherein the anti-PD-1 antibody is MDX-1106.

7. The method of claim 1 , wherein the anti-PD-1 antibody is Merck 3745.

8. The method of claim 1 , wherein the MEK inhibitor is G02443714, G02442104 or G00039805, or a pharmaceutically acceptable salt or solvate thereof.

9. The method of claim 1 , wherein the colorectal cancer or melanoma contains a BRAF V600E mutation.

10. The method of claim 1 , wherein the colorectal cancer or melanoma contains a BRAF wildtype.

11. The method of claim 1 , wherein the colorectal cancer contains a KRAS wildtype.

12. The method of claim 1 , wherein the colorectal cancer contains an activating KRAS mutation.

13. The method of claim 1 , wherein the treatment results in a sustained response in the individual after cessation of the treatment.

14. The method of claim 1 , wherein the MEK inhibitor is administered continuously.

15. The method of claim 1 , wherein the MEK inhibitor is administered intermittently.

16. The method of claim 1 , wherein the MEK inhibitor is administered before the anti-PD-1 antibody.

17. The method of claim 1 , wherein the MEK inhibitor is administered simultaneous with the anti-PD-1 antibody.

18. The method of claim 1 , wherein the MEK inhibitor is administered after the anti-PD-1 antibody.

19. The method of claim 1 , wherein the anti-PD-1 antibody is administered intravenously, intramuscularly, subcutaneously, topically, orally, transdermally, intraperitoneally, intraorbitally, by implantation, by inhalation, intrathecally, intraventricularly, or intranasally.

20. The method of claim 1 , wherein the MEK inhibitor is G02442104, or a pharmaceutically acceptable salt or solvate thereof.

21. The method of claim 1 , wherein the MEK inhibitor is G-38963, or a pharmaceutically acceptable salt or solvate thereof.

22. The method of claim 1 , wherein the MEK inhibitor is G02443714, or a pharmaceutically acceptable salt or solvate thereof.

23. The method of claim 1 , wherein the MEK inhibitor is G00039805, or a pharmaceutically acceptable salt or solvate thereof.

24. The method of claim 1 , wherein the MEK inhibitor is GDC-0973, or a pharmaceutically acceptable salt or solvate thereof.

25. The method of claim 1 , wherein the method is for treating or delaying progression of colorectal cancer in the individual, and the MEK inhibitor is GDC-0973 or a pharmaceutically acceptable salt or solvate thereof.

26. The method of claim 25 , wherein the anti-PD-1 antibody is MDX-1106.

27. The method of claim 25 , wherein the anti-PD-1 antibody is Merck 3745.

28. The method of claim 1 , wherein the method is for treating or delaying progression of melanoma in the individual, and the MEK inhibitor is GDC-0973 or a pharmaceutically acceptable salt or solvate thereof.

29. The method of claim 28 , wherein the anti-PD-1 antibody is MDX-1106.

30. The method of claim 28 , wherein the anti-PD-1 antibody is Merck 3745.
