Abstract

Agonists to ICOS in combination with a blocking agent to a T cell inhibitory receptor (e.g., CTLA-4, PD-1, etc.) are demonstrated herein to be useful for the treatment of tumors.

Claims

1. A method of treating cancer in a patient comprising administering to the patient simultaneously or sequentially a composition comprising a blocking anti-PD-1 antibody and an ICOS ligand.

5. The method of claim 1, wherein the ICOS ligand is soluble.

6. The method of claim 1, wherein the ICOS ligand is expressed on the surface of a cell.

7. The method of claim 6, wherein the cell is a tumor cell.

8. The method of claim 7, wherein the tumor cell is irradiated.

9. The method of claim 7, wherein the tumor cell was surgically removed from the patient.
