Method of treating cancer using immune checkpoint inhibitor
This disclosure provides a method for treating HPV-positive squamous cell carcinoma of the head and neck comprising administering to the subject an immune checkpoint inhibitor, e.g., an anti-PD-1 antibody or an anti-PD-L1 antibody. The disclosure also provides a method for treating HPV-negative squamous cell carcinoma of the head and neck administering to the subject an immune checkpoint inhibitor, e.g., an anti-PD-1 antibody or an anti-PD-L1 antibody. The subject can be additionally administered another anti-cancer agent.
1. A method for treating a human subject afflicted with a tumor derived from a human papilloma virus (HPV)-positive squamous cell carcinoma head and neck cancer (SCCHN) comprising administering to the subject a flat dose of 480 mg of nivolumab once every four weeks without regard for the weight of the subject.
2. A method of treating a human subject afflicted with a tumor derived from an HPV-positive SCCHN comprising:
(i) measuring a level of HPV in a sample of the subject, wherein the subject is positive for HPV; and
(ii) administering to the subject a flat dose of 480 mg of nivolumab once every four weeks without regard for the weight of the subject.
3. The method of claim 1 , wherein the HPV-positive SCCHN comprises a tumor expressing one or more proteins derived from an HPV or comprising a nucleotide sequence encoding the one or more proteins.
4. The method of claim 3 , wherein the one or more proteins derived from an HPV comprise p16, Ki-67, Cyclin D1, p53, ProEx C, E6, E7, or any combination thereof.
5. The method of claim 1 , wherein the HPV comprises HPV subtype 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68, or any combination thereof.
6. The method of claim 1 , wherein more than about 70% of tumor cells in the tumor show strong and diffuse nuclear and cytoplasmic staining by an immunohistochemistry against p16.
7. The method of claim 1 , wherein the tumor further expresses PD-L1.
8. The method of claim 1 , wherein the subject exhibits an overall survival of at least about 10 months after the administration.
9. The method of claim 1 , which further comprises administering one or more additional anti-cancer agents.
10. The method of claim 9 , wherein at least one of the anti-cancer agents is selected from the group consisting of (i) an antibody or antigen-binding portion thereof that binds specifically to a CTLA-4 and inhibits CTLA-4 activity, (ii) a chemotherapy, (iii) a platinum-based doublet chemotherapy, (iv) a tyrosine kinase inhibitor, (v) an anti-VEGF inhibitor, and (vi) any combination thereof.
11. The method of claim 1 , wherein the subject received one or more anti-cancer agents prior to the administration of the nivolumab.
12. The method of claim 11 , wherein the one or more anti-cancer agents were not effective in treating the tumor.
13. The method of claim 12 , wherein the one or more anti-cancer agents comprise a platinum-based therapy.
14. The method of claim 2 , wherein the subject exhibits an overall survival of at least about 10 months after the administration.
15. The method of claim 2 , wherein the HPV-positive SCCHN comprises a tumor expressing one or more proteins derived from an HPV or comprising a nucleotide sequence encoding the one or more proteins.
16. The method of claim 15 , wherein the one or more proteins derived from an HPV comprise p16, Ki-67, Cyclin D1, p53, ProEx C, E6, E7, or any combination thereof.
17. The method of claim 2 , wherein the HPV comprises HPV subtype 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68, or any combination thereof.
18. The method of claim 2 , wherein more than about 70% of tumor cells in the tumor show strong and diffuse nuclear and cytoplasmic staining by an immunohistochemistry against p16.
19. The method of claim 2 , wherein the tumor further expresses PD-L1.
