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.

Efficacy of EGFR-Tyrosine Kinase Inhibitors for advanced non-small cell lung cancer patients harboring rare EGFR mutations of exon 18 E709X. (PubMed, Med Oncol)

EGFR-tyrosine kinase inhibitors (TKIs) show efficacy against lung cancer, and afatinib has been used as a standard therapy for patients with non-small cell lung cancer (NSCLC) with EGFR rare mutations such as S768I, G719X, and L861Q...New treatment-related adverse events were not observed. NSCLC patients with exon 18 E709X mutations may benefit from treatment with second- or third-generation EGFR-TKIs.

NSCLC with uncommon EGFR mutations treated with atezolizumab plus bevacizumab and chemotherapy. (ASCO 2022)

Analysis included 16 stage IV NSCLC patients with uncommon EGFR mutations from 9 different German centers which started treatment in first or further line with Atezolizumab, Bevacizumab, Carboplatin and (nab-)Paclitaxel (ABCP) between October 2018 and January 2022...9 patients received a TKI therapy in first line (4x Afatinib; 5x Osimertinib) with an ORR of 66.7% (CR = 1; PR = 5; SD = 1; PD = 2) and a median time-to-next-treatment of 6.7 months (range: 2.1-39.1 months)... In this retrospective analysis, ABCP achieves an encouraging outcome for patients with uncommon EGFR mutations, comparable to results for common EGFR mutations in IMpower150 (ORR 71%, mPFS: 9.7 months, mOS 29.4 months). This in contrast to immunotherapy alone which shows poor ORR and PFS. Together with new targeted treatment options for Exon 20 insertions like amivantamab (ORR 40%, mPFS 8.3 months) or mobocertinib (ORR 28%, mPFS 7.3 months), ABCP is a valuable option in the early course of treatment for this patient cohort.

Of them, 6 patients received EGFR TKI treatment (4 gefitinib and 2 erlotinib). Conclusion Kras-G12C mutation was associated with shorter TTR in early-stage NSCLC patients, while Kras-G12V mutation was associated with shorter OS in advanced-stage patients. Kras-G12C was also associated with favorable ICIs treatment effectiveness.
