Abstract

Currently, treatments for patients with non‑small cell lung cancer harboring epidermal growth factor receptor (EGFR) mutations are limited after receiving multiple lines of therapy. Furmonertinib, a newly developed third‑generation EGFR‑tyrosine kinase inhibitor (TKI), has shown potential as a subsequent treatment. To explore efficacy and safety of furmonertinib, the present retrospective study analyzed patients with EGFR‑mutant advanced lung adenocarcinoma (LUAD) who received furmonertinib after the failure of multiple lines of therapy at the China‑Japan Friendship Hospital (Beijing, China) between December 2021 and April 2024. Data on patient demographics, treatment efficacy and safety outcomes were assessed until disease progression. A total of 25 patients with advanced LUAD were retrospectively included in the analysis. Among them, 15 (60.0%) harbored exon 19del, whilst 10 (40.0%) had exon21 L858R mutations. Pre‑treatment genetic testing was performed in 14 patients (56.0%). Prior to furmonertinib therapy, 17, 5 and 19 patients had previously received first‑, second‑ and third‑generation EGFR‑TKIs, respectively. The median line of treatment before furmonertinib was 3. The median progression‑free survival was 5.73 (95% confidence interval, 4.30‑not reached) months. The objective response rate was 16.0% (n=4) and the disease control rate was 88.0% (n=22). A total of 18 (72.0%) patients experienced at least one adverse event (AE). The rate of AEs was 80.0% (n=20) for grade 1‑2, and 20.0% (n=5) for grade 3‑4 AEs. No AEs led to treatment discontinuation, dose reductions or death. In conclusion, furmonertinib is a viable treatment option for patients with EGFR‑mutant advanced LUAD after the failure of multiple lines of therapy, even after resistance to treatment with third‑generation EGFR‑TKIs targeted agents. However, further large‑scale clinical studies are warranted to validate these findings.
