    Lazertinib for Patients with NSCLC Harboring Uncommon EGFR Mutations: A Single-Arm, Phase II Multi-Center Trial (IASLC-WCLC 2023)
    In this study, we observed the clinical benefit of 240mg Lazertinib in the treatment of naïve EGFR uncommon mutants. Among the mutations, G719X and L861Q showed promising outcomes, which are aligned with preclinical data. The safety profile was consistent with registry trials, indicating the necessity of further exploration for clinical efficacy in uncommon EGFR mutations on a larger scale.

    Nuclear export signal mutation of epidermal growth factor receptor enhances malignant phenotypes of cancer cells. (PubMed, Am J Cancer Res)
    Mechanistically, nuclear EGFR signaling is required for sustaining nuclear activated STAT3, but not for Erk. These findings suggest that EGFR functions are compartmentalized and that nuclear EGFR signaling plays a crucial role in tumor malignant phenotypes, leading to tumorigenesis in human cancer.

    An allosteric inhibitor against the therapy-resistant mutant forms of EGFR in non-small cell lung cancer. (PubMed, Nat Cancer)
    We further uncover that EGFR homo- or heterodimerization with other ERBB family members, as well as the EGFR L747S mutation, confers resistance to JBJ-09-063, but not to ATP-competitive EGFR TKIs. Overall, our studies highlight the potential clinical utility of JBJ-09-063 as a single agent or in combination with EGFR TKIs to define more effective strategies to treat EGFR-mutant lung cancer.

    As for patients treated with EGFR TKIs, three EGFR L747P patients achieved partial response through afatinib treatment, and two EGFR L747S patient achieved progressive disease to icotinib treatment. Figure 1. Chest computed tomography images before (at baseline) and after treatment with afatinib in patients 2.
