COMBINATION OF A PD-1 ANTAGONIST AND A VEGFR INHIBITOR FOR TREATING CANCER
The present disclosure describes combination therapies comprising an antagonist of Programmed Death 1 receptor (PD-1) and a VEGFR inhibitor, and the use of the combination therapies for the treatment of cancer, and in particular for treating cancers that express PD-L 1.
1 . A method for treating a cancer in an individual comprising administering to the individual a combination therapy which comprises an antagonist of a Programmed Death 1 protein (PD-1) and a vascular endothelial growth factor receptor (VEGFR) inhibitor, wherein the PD-1 antagonist is an anti-PD-1 monoclonal antibody which comprises a heavy chain and a light chain, wherein the heavy and light chains comprise SEQ ID NO:21 and SEQ ID NO:22, respectively, and further wherein the VEGFR inhibitor is N-methyl-2-[3-((E)-2-pyridin-2-yl-vinyl)-1H-indazol-6-ylsulfanyl]-benzamide or a pharmaceutically acceptable salt thereof, wherein the cancer tested positive for Programmed Death Ligand 1 (PD-L1) expression by an immunohistochemical (IHC) assay.
2 . The method of claim 1 , wherein the individual is a human.
3 . The method of claim 1 , wherein the cancer is a solid tumor.
4 . The method of claim 1 , wherein the cancer is renal cell carcinoma.
5 . The method of claim 1 , wherein the PD-1 antagonist is pembrolizumab and the VEGFR inhibitor is axitinib.

18 . The method of claim 17 , wherein the cancer is advanced renal cell carcinoma.
19 . A method for treating a human individual diagnosed with a cancer, comprising administering to the individual a combination therapy which comprises pembrolizumab and axitinib, wherein (a) axitinib is administered at a dose of 5 mg twice daily (BID) and pembrolizumab is administered at a dose selected from the group consisting of 1 mg/kg every three weeks (Q3W), 2 mg/kg Q3W and 200 mg Q3W or (b) axitinib is administered at a dose of 3 mg BID and pembrolizumab is administered at a dose selected from the group consisting of 1 mg/kg Q3W, 2 mg/kg Q3W and 200 mg Q3W, wherein a tissue section of the cancer removed from the individual prior to administration of the combination therapy tested positive for PD-L1 expression.
20 . (canceled)
21 . The method of claim 1 , wherein the PD-1 antagonist is pembrolizumab.
22 . The method of claim 1 , wherein at least 1% of total tumor cells in a tissue section of the cancer exhibited histologic evidence of cell-surface membrane staining.
23 . The method of claim 1 , wherein at least 5% of total tumor cells in a tissue section of the cancer exhibited histologic evidence of cell-surface membrane staining.
24 . The method of claim 19 , wherein the cancer is renal cell carcinoma.
25 . The method of claim 19 , wherein said pembrolizumab is provided at a dose of 200 mg Q3W.
26 . The method of claim 19 , comprising administering to the individual a combination therapy which comprises pembrolizumab and axitinib, wherein axitinib is administered at a dose of 5 mg twice daily (BID) and pembrolizumab is administered at a dose of 1 mg/kg every three weeks (Q3W).
27 . The method of claim 19 , comprising administering to the individual a combination therapy which comprises pembrolizumab and axitinib, wherein axitinib is administered at a dose of 5 mg twice daily (BID) and pembrolizumab is administered at a dose of 2 mg/kg Q3W.
28 . The method claim 19 , comprising administering to the individual a combination therapy which comprises pembrolizumab and axitinib, wherein axitinib is administered at a dose of 5 mg twice daily (BID) and pembrolizumab is administered at a dose of 200 mg Q3W.
29 . The method of claim 19 , comprising administering to the individual a combination therapy which comprises pembrolizumab and axitinib, wherein axitinib is administered at a dose of 3 mg twice daily (BID) and pembrolizumab is administered at a dose of 1 mg/kg every three weeks (Q3W).
30 . The method of claim 19 , comprising administering to the individual a combination therapy which comprises pembrolizumab and axitinib, wherein axitinib is administered at a dose of 3 mg twice daily (BID) and pembrolizumab is administered at a dose of 2 mg/kg Q3W.
31 . The method of claim 19 , comprising administering to the individual a combination therapy which comprises pembrolizumab and axitinib, wherein axitinib is administered at a dose of 3 mg twice daily (BID) and pembrolizumab is administered at a dose of 200 mg Q3W.
32 . The method of claim 19 , wherein at least 1% of total tumor cells in the tissue section of the cancer exhibited histologic evidence of cell-surface membrane staining.
33 . The method of claim 19 , wherein at least 5% of total tumor cells in the tissue section of the cancer exhibited histologic evidence of cell-surface membrane staining.
