comparison of neoadjuvant cadonilimab versus chemotherapy combined with pd-1 in the treatment of resectable non-small cell lung cancer with high pd-l1 expression: a single-center, randomized, exploratory clinical study

Conditions: Resectable Non-small Cell Lung Cancer; Bispecific Antibody; Neoadjuvant Therapy

Summary: the advent of immunotherapy has changed the treatment landscape for patients with non-small cell lung cancer. it has become the mainstay of perioperative treatment for patients with resectable non-small cell lung cancer。 cadonilimab is the world's first bispecific antibody drug targeting pd-1 and ctla-4. previous studies on ak104 have demonstrated preliminary efficacy in both treatment-naïve advanced nsclc patients and immunotherapy-resistant patients, showing a favorable safety and tolerability profile. this study aims to evaluate the effectiveness of neoadjuvant bispecific antibody ak104 compared with neoadjuvant chemotherapy combined with a pd-1 inhibitor in the treatment of resectable non-small cell lung cancer (nsclc) with high pd-l1 expression.
