Summary

This study tests whether a combination of targeted drugs (trastuzumab deruxtecan, capecitabine, and durvalumab) can shrink HER2-positive stomach or gastroesophageal junction cancer before surgery and prevent return after surgery. About 64 adults with untreated, advanced but not spread cancer will participate. The main goal is to see how many patients have little to no tumor left after treatment.
