Study of Furmonertinib as Neoadjuvant Therapy for Resectable Stage Ⅱ-ⅢB EGFR Sensitive Mutant NSCLC

EGFR-TKI has firmly established itself as a first-line treatment for advanced lung cancer with EGFR-sensitive mutations, and the ADAURA study has added to its indications for use as postoperative adjuvant therapy in early- and mid-stage lung cancer.However, clinical data on neoadjuvant EGFR-TKI therapy are still incomplete. A phase II clinical study, CTONG1103, currently ongoing, comparing the efficacy of the first generational EGFR-TKI erlotinib and gemcitabine combined with cisplatin as neoadjuvant therapy for stage IIIA-N2 EGFR mutation-positive non-small-cell lung cancer, did not yield significantly positive objective remission rate (ORR) results. Furmonertinib is a third-generation Epidermal Growth Factor Receptor (EGFR) tyrosine kinase inhibitor (TKI) that targets Epidermal Growth Factor Receptor (EGFR) mutations.Furmonertinib demonstrates definite efficacy and favorable safety in first-line EGFR-sensitive mutations and EGFR T790M Mutations in second-line and late-line treatment of advanced NSCLC.The aim of this study was to explore the efficacy and safety of furmonertinib neoadjuvant therapy for resectable stage II-IIIB EGFR-sensitive mutant non-small cell lung cancer efficacy and safety. Patinents are planned to be recruited from five centers in China. Eligible patients will receive furmonertinib neoadjuvant therapy for 8 weeks to evaluate the efficacy and safety of furmonnertinib neoadjuvant.
