Neoadjuvant immunotherapy combined with chemotherapy followed by surgery has become an important treatment strategy for resectable non-small cell lung cancer (NSCLC). However, patients who do not achieve a pathological complete response (non-pCR) after neoadjuvant treatment remain at a high risk of disease recurrence, and optimal postoperative adjuvant treatment for these patients remains unclear. Adebrelimab, an immune checkpoint inhibitor targeting PD-L1, and famitinib, a multitarget tyrosine kinase inhibitor with antiangiogenic activity, may have complementary antitumor effects. Therefore, we conduct this prospective, single-arm, phase II clinical trial to investigate the efficacy and safety of adebrelimab combined with famitinib as postoperative adjuvant therapy in patients with resectable NSCLC who did not achieve pCR after neoadjuvant chemoimmunotherapy followed by surgery.
