This clinical trial is focused on studying a type of cancer called HER2-positive esophageal adenocarcinoma. This is a cancer that affects the esophagus, which is the tube that carries food from the mouth to the stomach. The study is investigating the effects of adding two medications, trastuzumab and pertuzumab, to the usual treatment of chemotherapy and radiation before surgery. These medications are given as a solution through an infusion, which means they are delivered directly into the bloodstream through a vein.
The purpose of the study is to see if adding trastuzumab and pertuzumab can help improve the overall survival of patients with this type of cancer. Participants in the study will receive either the standard treatment or the standard treatment plus the two additional medications. Some participants may receive a placebo instead of the additional medications. The study will follow participants over a period of time to monitor their health and the effectiveness of the treatment.
Throughout the study, researchers will look at various outcomes, including how long patients live, how well the cancer responds to treatment, and the quality of life of the participants. The study will also assess the safety of the treatment by monitoring any side effects or complications that may occur. The goal is to gather information that could lead to better treatment options for people with HER2-positive esophageal adenocarcinoma in the future.
