ASCO GI 2025 | Dr. Zhi Peng: Five-Year Survival Benefits from CheckMate 649 Bring New Hope for a Cure in Gastric Cancer Patients
CheckMate 649 is the first global Phase III trial to successfully evaluate a first-line immunotherapy regimen (nivolumab + chemotherapy) for advanced gastric cancer. The study’s primary results were first unveiled at the 2020 European Society for Medical Oncology (ESMO) Congress, and the pre-specified China subgroup data were presented for the first time at the 2021 American Association for Cancer Research (AACR) meeting. The findings demonstrated even greater benefits in Chinese patients compared to the global population, generating significant academic interest and establishing first-line immunotherapy plus chemotherapy as the standard of care for advanced gastric cancer in China. Today, nivolumab in combination with chemotherapy has been approved as a first-line treatment for advanced or metastatic gastric cancer (GC), gastroesophageal junction cancer (GEJC), and esophageal adenocarcinoma (EAC) in more than 50 countries, including the United States and China.
