Abstract

Single-agent immunotherapy has achieved limited clinical benefit to date in patients with pancreatic ductal adenocarcinoma (PDAC). This may be a result of the presence of a uniquely immunosuppressive tumor microenvironment (TME). Critical obstacles to immunotherapy in PDAC tumors include a high number of tumor-associated immunosuppressive cells and a uniquely desmoplastic stroma that functions as a barrier to T cell infiltration. We identified hyperactivated focal adhesion kinase (FAK) activity in neoplastic PDAC cells as an important regulator of the fibrotic and immunosuppressive TME. We found that FAK activity was elevated in human PDAC tissues and correlated with high levels of fibrosis and poor CD8(+) cytotoxic T cell infiltration. Single-agent FAK inhibition using the selective FAK inhibitor VS-4718 substantially limited tumor progression, resulting in a doubling of survival in the p48-Cre;LSL-Kras(G12D);Trp53(flox/+) (KPC) mouse model of human PDAC. This delay in tumor progression was associated with markedly reduced tumor fibrosis and decreased numbers of tumor-infiltrating immunosuppressive cells. We also found that FAK inhibition rendered the previously unresponsive KPC mouse model responsive to T cell immunotherapy and PD-1 antagonists. These data suggest that FAK inhibition increases immune surveillance by overcoming the fibrotic and immunosuppressive PDAC TME and renders tumors responsive to immunotherapy.

  • Targeting FAK in cancer cells concomitantly reduces stromal fibroblast activation and development of an immunosuppressive environment.

    “and targeting focal adhesion kinase (FAK) in cancer cells concomitantly reduces stromal fibroblast activation and the development of an immunosuppressive environment123.”
  • Randomized clinical trials combining PEG-hyaluronidase with standard-of-care chemotherapy for advanced PDAC did not increase overall survival, regardless of chemotherapy backbone or selection of patients with high hyaluronic acid by immunostaining.

  • FAK inhibition may enhance KRAS (G12C) inhibition and immunotherapy.

    “Thus, FAK inhibition may enhance KRAS (G12C) inhibition and immunotherapy [125, 126].”
  • FAK-related fibrosis can form a barrier in tumors that limits the CD8+ T cells infiltration in tumors, and FAK inhibition can ultimately promote the antitumor effects by decreasing the number of tumor-resident Tregs.

    “FAK-related fibrosis can form a barrier in tumors that limits the CD8+ T cells infiltration in tumors, and FAK inhibition can ultimately promote the antitumor effects by decreasing the number of tumor-resident Tregs.”
  • FAK signaling regulates fibrogenesis within tumors.

    “FAK signaling has been reported to regulate fibrogenesis within tumors,[ 17, 48 ] and excessive fibrosis is correlated with drug resistance, because it can create a barrier that prevents interactions between cancer cells and therapeutic agents.[ 49 ]”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
