Summary

This study looks at whether the bacteria in your gut can help predict how well a combination of immunotherapy and chemotherapy works for advanced stomach cancer. About 300 adults with metastatic or locally advanced stomach cancer who haven't had chemo or immunotherapy before will receive standard chemo plus a PD-1 inhibitor. Researchers will check gut bacteria at three points during treatment to see if it relates to how long the cancer stays under control.
