Study Summary

Zolbetuximab is being studied in people with cancer in and around the stomach or where the food pipe (esophagus) joins the stomach, called gastroesophageal junction (GEJ) cancer. Zolbetuximab with chemotherapy may be used to treat stomach and GEJ cancer when the cancer cells do not have a protein called HER2 (human epidermal growth factor receptor 2) on their surface (HER2-negative) but do have a protein called Claudin 18.2 (Claudin 18.2-positive). Zolbetuximab is thought to work by attaching to the Claudin 18.2 protein in their tumor, which switches on the body's immune system to attack the tumor. Certain stomach and GEJ cancers may be treated with immunotherapy, which helps the body's immune system fight cancer. This study will give more information about how well zolbetuximab works when given with an immunotherapy medicine called pembrolizumab and chemotherapy. In this study, adults with stomach cancer or GEJ cancer will either be given zolbetuximab with pembrolizumab and chemotherapy or a placebo with pembrolizumab and chemotherapy. A placebo looks like zolbetuximab but doesn't have any medicine in it. The main aim of the study is to check how long people with stomach cancer and GEJ cancer live after treatment with zolbetuximab with pembrolizumab and chemotherapy compared to placebo with pembrolizumab and chemotherapy. Adults with locally advanced unresectable or metastatic stomach cancer or GEJ cancer can take part. Locally advanced means the cancer has spread to nearby tissue. Unresectable means the cancer cannot be removed by surgery. Metastatic means the cancer has spread to other parts of the body. A tumor sample (biopsy) of their cancer will have the Claudin 18.2 protein, PD-L1 protein, and be HER2-negative. They may have been previously treated with certain standard therapies. People cannot take part if they need to take medicines to suppress their immune system, have blockages or bleeding in their gut, have specific uncontrollable cancers such as sympt
