CHIO3 Trial: CHemotherapy Combined With Immune Checkpoint Inhibitor for Operable Stage IIIA/B Non-Small Cell Lung Cancer

This is a single arm, phase II trial of combined neoadjuvant platinum doublet chemotherapy plus durvalumab followed by surgery, postoperative radiation and adjuvant durvalumab for 13 cycles for patients with potentially resectable stage IIIA and IIIB (T1-3, N2) NSCLC (per the 8th International Association for the Study of Lung Cancer classification). The primary objective of this study is to increase N2 nodal clearance (N2NC) to 50% or greater for combined platinum doublet chemotherapy with durvalumab induction therapy from historical rate of 30% for platinum doublet chemotherapy alone in patients with potentially resectable stage IIIA/B (N2) NSCLC.
