Nanjing, JiangsuAges 18–75 - NCT06038578RecruitingPhase 2
TRK-950 with standard chemo for advanced stomach cancer
This trial tests a new drug, TRK-950, added to standard chemotherapy (ramucirumab and paclitaxel) for people with advanced stomach or gastroesophageal junction cancer that has worsened after previous treatment. The goal is to see if this combination can help shrink tumors or slow disease progression.

DA 3501 for advanced stomach or pancreatic cancer
This trial tests a new drug, DA 3501, in people with advanced stomach or pancreatic cancer that has a specific protein called CLDN18.2. It aims to see if the drug is safe and effective.
Seongnam, BundangAges 19 years+ - NCT06846996Recruiting
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+ - NCT07001748RecruitingPhase 2/Phase 3
Testing abdominal chemo plus standard chemo for stomach cancer spread
This trial tests adding the chemotherapy drug paclitaxel directly into the abdomen (intraperitoneal) along with standard IV chemotherapy for people with stomach or gastroesophageal junction cancer that has spread to the lining of the abdomen. The goal is to see if this combination helps control the cancer better than standard treatment alone.
