Summary
Brief summary
This study is being done to find out if zanidatamab, when given with chemotherapy plus or
minus tislelizumab, is safe and works better than trastuzumab given with chemotherapy.

stomach and esophageal cancers that are no longer treatable with surgery (unresectable) or
chemoradiation, and/or have grown or spread to other parts of the body (metastatic).
