절제 가능한 고PD-L1 비소세포폐암에 대한 수술 전후 세미플리맙 투여

This is a single arm phase II trial enrolling patients with stage II-IIIA non-small cell lung cancer whose disease is deemed amenable for surgical resection and has a PD-L1 level of ≥50%. Patients will receive cemiplimab for 3 cycles followed by surgical resection. The primary endpoint evaluated by the study is the amount of residual tumor in the resected tissue after 3 cycles of cemiplimab. After surgery, all patients will receive additional 10 cycles of cemiplimab and the treating oncologist will decide on the need of administering chemotherapy prior to that.
