Study of trastuzumab deruxtecan for advanced stomach cancer
This study looks at how well the drug trastuzumab deruxtecan (T-DXd) works and how safe it is in people with advanced HER2-positive stomach or gastroesophageal junction cancer in China. It may be an option if you have already had other treatments.
BeijingAges 18 years+ - NCT07025889RecruitingPhase 1/Phase 2
IBI343 plus sintilimab and chemo for gastric cancer
This trial tests a new combination of IBI343, sintilimab, and chemotherapy for people with advanced stomach or gastroesophageal junction cancer that hasn't been treated yet. It's for those whose tumors are CLDN18.2-positive and not HER2-positive.
