CZC54252 overcomes Osimertinib resistance by targeting EGFR C797S mutations in NSCLC

The introduction of EGFR inhibitors has revolutionized the management of NSCLC, leading to a significant extension of survival in the target patient population. Unfortunately, acquired resistance appears to be unavoidable, which restricts the use of EGFR‑TKIs in the clinic. EGFR^C797S represents a novel resistant mutation after treatment with the latest generation of EGFR inhibitor Osimertinib. Consequently, developing next‑generation EGFR‑TKIs targeting such resistant mutations is strongly demanded. ...These data indicate that CZC54252 represents a promising lead compound for overcoming Osimertinib resistance by targeting EGFR^C797S, which provides a chemical basis for the development of novel fourth‑generation EGFR inhibitors.

The emergence of EGFR C797S triple mutations as a common mechanism of acquired resistance to third‑generation EGFR inhibitors, such as Osimertinib, poses a major therapeutic challenge in NSCLC. Identifying a compound that can specifically target these mutations provides a critical step toward a clinically viable fourth‑generation inhibitor that can restore efficacy in patients whose tumors have progressed on Osimertinib.
