Stromal reprogramming overcomes resistance to RAS-MAPK inhibition to improve pancreas cancer responses to cytotoxic and immune therapy. (PubMed, Sci Transl Med)
Concomitant inhibition of both FAK (with VS-4718) and rapidly accelerated fibrosarcoma and MAPK kinase (RAF-MEK) (with avutometinib) induced tumor growth inhibition and increased survival across multiple PDAC mouse models. Combination of FAK and RAF-MEK inhibition alone improved antitumor immunity and priming of T cell responses in response to chemotherapy. These findings provided the rationale for an ongoing clinical trial evaluating the efficacy of avutometinib and defactinib in combination with gemcitabine and nab-paclitaxel in patients with PDAC and may suggest further paths for combined stromal and tumor-targeting therapies.

Preclinical evaluation of avutometinib and defactinib in high-grade endometrioid endometrial cancer. (PubMed, Cancer Med)
Avutometinib, defactinib, and to a larger extent their combinations, demonstrated promising in vitro and in vivo activity against EAC cell lines and xenografts. These preclinical data support the potential clinical evaluation of this combination in high-grade EAC patients.

Exosomal CTHRC1 from cancer-associated fibroblasts facilitates endometrial cancer progression via ITGB3/FAK signaling pathway. (PubMed, Heliyon)
Overexpression of CTHRC1 in secreted exosomes promotes the metastatic ability of EC cells in mouse models and may be eliminated by Defactinib, an inhibitor of FAK Tyr397 phosphorylation. Moreover, overexpression of CTHRC1 was increased in EC patients, elevating with cancer progression, and correlated with negative tumor prognosis. Our results revealed that CAF mediated endometrial cancer progression is related to high levels of CTHRC1 and exosomal CTHRC1 derived from CAF may be a promising therapeutic strategy for metastatic endometrial cancer.

Injectable hybrid hydrogels enable enhanced combination chemotherapy and roused anti-tumor immunity in the synergistic treatment of pancreatic ductal adenocarcinoma. (PubMed, J Nanobiotechnology)
With only a single intratumoral injection, the combination treatment with erastin and defactinib produces further anti-tumor performance both in xenograft and KrasG12D-engineered primary PDAC mice and synergistically promotes the infiltration of CD8+ cytotoxic T cells and the reduction of type II macrophages. The findings may provide a novel promising strategy for the clinical treatment of PDAC.

PTK2 is a potential biomarker and therapeutic target for EGFR- or TLRs-induced lung cancer progression via the regulation of the cross-talk between EGFR- and TLRs-mediated signals. (PubMed, Biomark Res)
Finally, therapeutic effects targeted to PTK2 in lung cancer in response to EGF and TLR agonists were verified by using its inhibitor (Defactinib). In summary, we identified that up-regulated PTK2 might be a reliable marker for EGFR- or TLRs-induced lung cancer progression in NSCLC patients via the regulation of the cross-talk between EGFR- and TLRs-mediated signaling. This study provides a theoretical basis for the therapeutic intervention of PTK2 targeting EGFR- or TLRs-induced lung cancer progression.

Integrin β4 Regulates Cell Migration of Lung Adenocarcinoma Through FAK Signaling. (PubMed, Mol Biotechnol)
Focal adhesion kinase (FAK) inhibitor defactinib was used to further explore the molecular mechanism of ITGB4...In addition, ITGB4 could interact with FAK in lung adenocarcinoma cells. ITGB4 may promote cell migration of lung adenocarcinoma through FAK signaling pathway and has the potential to be a biomarker for lung adenocarcinoma.

Annotation of CD8 T-cell function via ICAM-1 imaging identifies FAK inhibition as an adjuvant to augment the antitumor immunity of radiotherapy. (PubMed, Theranostics)
Mechanistically, VS-6063 overcomes the physical barriers in tumors and promotes the migration and infiltration of CD8 T cells primed by RT into distant tumors. Our findings highlight that molecular imaging of ICAM-1 levels provides a dynamic readout of the proliferation and effector function of tumor-infiltrating CD8 T cells, which facilitates the high-throughput exploitation of new combinational drugs to maximize the systemic antitumor effect of RT.

Evaluating the therapeutic effects of small molecule inhibitors of CDK4/6 and FAK in preclinical meningioma models (SNO 2023)
In vitro, cell viability and proliferation assays were used to test abemaciclib (CDK4/6 inhibitor), defactinib (FAK inhibitor) and VS-6766 (RAF/MEK inhibitor) as monotherapy and in combination...The efficacy of VS-4718 (in vivo formulation of defactinib) and abemaciclib were evaluated in a subcutaneous IOMM-lee meningioma model (having CDKN2A loss) in nude mice... Abemaciclib showed promising efficacy in preclinical meningioma xenografts with CDKN2A loss. Studies to evaluate these therapies in other orthotopic models are underway.

FTO facilitates cancer metastasis by modifying the mA level of FAP to induce integrin/FAK signaling in non-small cell lung cancer. (PubMed, Cell Commun Signal)
Our current findings provided valuable insights into the role of FTO-mediated mA demethylation modification in NSCLC metastasis. FTO was identified as a contributor to NSCLC metastasis through the activation of the FAP/integrin/FAK signaling, which may be a potential therapeutic target for NSCLC. Video Abstract.

Focal adhesion kinase activation by calcium-dependent calpain is involved in chronic lymphocytic leukaemia cell aggressiveness. (PubMed, Br J Haematol)
Treatment with the FAK inhibitor Defactinib was able to induce apoptosis in CLL cells. In conclusion, the malignant phenotype in unfavourable-prognosis patients seems to be encouraged by the overexpression of cortactin and HS1, that, together with FAK, may be involved in a druggable pathogenetic pathway in CLL.
