Peking Cancer Hospital Team’s PD-1/CTLA-4 Dual-Target Antibody Combined with Chemotherapy as First-Line Treatment for Advanced Gastric Cancer
Dr. Jiafu Ji, Dr. Ziyu Li, and Dr. Lin Shen from Peking Cancer Hospital have co-authored a research paper titled “Cadonilimab with chemotherapy in HER2-negative gastric or gastroesophageal junction adenocarcinoma: the phase 1b/2 COMPASSION-04 trial”, published online in Nature Medicine. The study addresses several critical clinical issues, such as the limited benefit of PD-1 monoclonal antibody treatment, the high incidence of adverse effects with PD-1 and CTLA-4 combination therapy, and the ineffectiveness of PD-1 combined with chemotherapy in patients with low or negative CPS scores. To tackle these challenges, the researchers innovatively employed a domestically developed PD-1/CTLA-4 dual-target antibody in the COMPASSION-04 study, marking the first clinical trial globally to evaluate this combination as a first-line treatment for advanced gastric cancer.
