Cadonilimab Monotherapy as Neoadjuvant Therapy for Resectable II-IIIA Squamous Cell Lung Cancer

An Open-label, Single-center, Phase II Study of Cadonilimab Monotherapy as Neoadjuvant Therapy for Resectable II-IIIA Squamous Cell Lung Cancer

Cadonilimab, a tetravalent bispecific antibody targeting PD-1 and CTLA-4, is designed to retain the efficacy benefit of combination of PD-1 and CTLA-4 and improve on the safety profile of the combination therapy. The aim of this study is to evaluate the efficacy and safety of Cadonilimab monotherapy as neoadjuvant therapy for patients with resectable stage II-IIIA squamous cell lung cancer.
