A Phase II Clinical Study of Cadonilimab in Combination With Chemotherapy as First-Line Treatment for PD-L1 Negative Advanced Non-Small Cell Lung Cancer

2023LY0204

The goal of this clinical trial is to investigate the efficacy, safety and tolerability of PD-1/CTLA-4 inhibitor (Cadonilimab) combination with chemotherapy as first-line treatment for PD-L1 negative advanced non small cell lung cancer patients. And also explore the potential biomarkers for predicting the efficacy of PD-1/CTLA-4 inhibitor for advanced non small cell lung cancer.

Exclusion Criteria: * Currently participating in interventional clinical research treatment; * Previously received the following therapies: anti-PD-1, anti-PD-L1, or anti-PD-L2 drugs, or drugs targeting another stimulatory or co-inhibitory T-cell receptor (such as CTLA-4, OX-40, CD137); * Received traditional Chinese medicine or immunomodulatory drugs (such as thymopeptide, interferon, interleukin, etc.) with anti-tumor indications within 2 weeks prior to the first dose; * Known allergy to the active ingredient or any excipients of Cadonilimab; * Active hemoptysis, active diverticulitis, intra-abdominal abscess, gastrointestinal obstruction, or peritoneal metastasis requiring clinical intervention; * Uncontrolled pleural effusion/ascites clinically (patients who do not require drainage of effusion or whose effusion does not increase significantly for 3 days can be included); * Tumor compression of important organs (such as the esophagus) with accompanying symptoms, compression of the superior vena cava, or invasion of mediastinal large blood vessels, heart, etc.; * History of severe complications such as severe pulmonary or cardiac disease, with any arterial thrombosis, embolism, or ischemia occurring within 6 months prior to enrollment, such as myocardial infarction, unstable angina, cerebrovascular accident, or transient ischemic attack.
