Abstract
Addressing resistance to third-generation EGFR TKIs such as osimertinib via the EGFRC797S mutation remains a highly unmet need in EGFR-driven non-small-cell lung cancer (NSCLC). Herein, we present the discovery of the allosteric EGFR inhibitor 57, a novel fourth-generation inhibitor to overcome EGFRC797S-mediated resistance in patients harboring the activating EGFRL858R mutation. 57 exhibits an improved potency compared to previous allosteric EGFR inhibitors. To our knowledge, 57 is the first allosteric EGFR inhibitor that demonstrates robust tumor regression in a mutant EGFRL858R/C797S tumor model. Additionally, 57 is active in an H1975 EGFRL858R/T790M NSCLC xenograft model and shows superior efficacy in combination with osimertinib compared to the single agents. Our data highlight the potential of 57 as a single agent against EGFRL858R/C797S and EGFRL858R/T790M/C797S and as combination therapy for EGFRL858R- and EGFRL858R/T790M-driven NSCLC.
