Abstract

The present invention describes combination treatment comprising a PD-1 axis binding antagonist and an agent that decreases or inhibits TIGIT expression and/or activity 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 or chronic infection.

Claims

2. A method for treating or delaying progression of an immune related disease in an individual comprising administering to the individual an effective amount of a PD-1 axis binding antagonist and an agent that decreases or inhibits TIGIT expression and/or activity.

3. The method of claim 2, wherein the immune related disease is associated with a T cell dysfunctional disorder.

4. The method of claim 3, wherein the T cell dysfunctional disorder is characterized by T cell exhaustion.

5. The method of claim 2, wherein the immune related disease is selected from the group consisting of unresolved acute infection, chronic infection, and tumor immunity.

6. A method of treating or delaying progression of cancer in an individual comprising administering to the individual an effective amount of a PD-1 axis binding antagonist and an agent that modulates CD226 expression and/or activity.
