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.

defined as the percentage of participants achieving complete surgical resection following completion of neoadjuvant therapy. |
| After surgery (approximately 7 weeks) |
| Objective Response Rate (ORR) | defined as the percentage of participants having complete response or partial response to protocol treatment. Objective response will be measured by RECIST 1.1. | At the end of 2 cycles of neoadjuvant therapy (each cycle is 21 days) |
| Disease Free Survival (DFS) | defined as the time from the first dose of study drug to disease progression per RECIST 1.1 that precludes surgery, local or distant recurrence, or death due to any cause, whichever occurs first. | Up to approximately 5 years |
| Adverse Events (AEs) | From the first dose of neoadjuvant treatment until 90 days after the last dose of adjuvant treatment |
