Neoadjuvant Almonertinib Followed by Chemo-immunotherapy in II-IIIB EGFR-mutant NSCLC

Overview

Phase II, single-arm, open-label study that assess clinical feasibility and safety of neoadjuvant almonertinib followed by 3 cycles neoadjuvant adebrelimab plus chemotherapy in EGFR-mutant stage IIA-IIIB NSCLC followed by surgery, adjuvant treatment was upon investigators' decisions.

This study plans to include 32 eligible II-IIIB non small cell lung cancer (NSCLC), patients will receive 6 weeks of almonertinib, and to avoid overlap of interstitial lung disease (ILD) and immune-related pneumonitis, 2 weeks of washout period was designed before 3 cycles of adebrelimab + doublet platinum-based chemotherapy is administered. Dynamic blood samples before, during or after neoadjuvant treatment will be obtained for exploratory analysis. Patients with local disease and resectable or potentially resectable NSCLC will receive anatomic resection. Patients who progress upon neoadjuvant treatment and further assessed as unresectable disease will be scheduled for local radiation or other potential subsequent treatment regarding multidisciplinary discussion. After completion of local treatment (surgery or radiation), patients will undergo optional adjuvant treatment including epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) or immunotherapy upon investigators' consideration or CT surveillance. Patients will be follow-up within 5 years after surgery. The primary endpoint of this study is major pathological response (MPR) defined as no more than 10% residual tumor found in primary lung cancer as per International Association for the Study of Lung Cancer (IASLC) criteria.
