Likewise, a combination of selective inhibitors of KRAS (RMC-6236/daraxonrasib), EGFR family (afatinib), and STAT3 (SD36) induced the complete regression of orthotopic PDAC tumors with no evidence of tumor resistance for over 200 d posttreatment...Of importance, this combination therapy was well tolerated. In sum, these results should guide the development of new clinical trials that may benefit PDAC patients.
We evaluated this nanocarrier-based therapeutic strategy for delivering the KRASG12D inhibitor MRTX1133 in KRASG12D-mutant cell lines and animal models...Mechanistically, it reprograms the tumor microenvironment by sustaining MAPK and PI3K pathway inhibition, reducing EGFR phosphorylation, enhancing CD8+ T-cell infiltration, and restoring antitumor immunity through PD-L1 blockade. By exploiting the signaling vulnerabilities of KRAS-driven tumors, our hybrid nanovesicle platform provides a promising therapeutic strategy for overcoming resistance and improving therapeutic response in KRAS-mutant NSCLC.
