Abstract: Described herein is the combination of STING/TLR4 agonist nanoparticles (NPs) and a combination of a MEK inhibitor (e.g., trametinib) and CDK4/6 inhibitor (e.g., palbociclib) treatment. This combination synergizes to (a) lead to enhanced NP uptake in multiple cell types in the TME, (b) increased antigen presentation on tumors cells as well as APCs, and (c) CD8+ T cell mediated long-term tumor control that is interferon signaling dependent. Also provided are methods to treat cancer, e.g., KRAS mutant cancers, e.g., KRAS mutant PDAC or lung cancer.

Abstract: Described herein are methods for preventing or treating KRAS mutant pancreatic cancer in a subject in need thereof comprising administering to the subject an effective amount of (i) an effective amount of a PRC2 inhibitor, (ii) an effective amount of a MEK inhibitor, (ii) and an effective amount of a CDK4/6 inhibitor, as well as compositions and kits for use in said methods.

Abstract: The present technology provides methods for treating pancreatic cancer using a MEK inhibitor and a CDK4/6 inhibitor. Also disclosed herein are methods for increasing patient responsiveness to chemotherapeutic and/or immunotherapeutic regimes for pancreatic cancer. Kits for use in practicing the methods are also provided.
