| abstract |
The present invention provides methods of treating and/or inhibiting cancer by administering a JAK1/2 inhibitor (e.g., ruxolitinib). The JAK1/2 inhibitor decreases expression of (or inhibits increased expression of) the checkpoint proteins PD-1, PD-L1, PD-L2, or B7 H3, and/or enhances T-cell killing of tumor cells, and/or enhances the anti-tumor effects of checkpoint inhibitors. The disclosed methods improve the efficacy of immune-based therapies used in treatment of cancer. |
