IBI363 (PD-1/IL-2α-bias) in Combination With Chemotherapy as Neoadjuvant Therapy in Initially Unresectable Stage III Non-Small Cell Lung Cancer

NSCLC patients receive IBI363 combined with platinum-based chemotherapy. If multidisciplinary team (MDT) assessment determines the patient is surgically eligible, surgery is performed followed by 1 year of standard adjuvant therapy. If, after 4 treatment cycles, MDT assessment determines the tumor remains unresectable, concurrent chemoradiotherapy followed by immune checkpoint inhibitor consolidation therapy is administered. This study aims to evaluate the efficacy of IBI363 combined with chemotherapy for neoadjuvant treatment of initially unresectable NSCLC based on R0 resection rate, major pathological response (MPR) rate, and pathological complete response (pCR) rate.
