This clinical trial is focused on studying certain types of gastrointestinal cancers, specifically colorectal cancer, biliary tract cancer, and hepatocellular carcinoma. The treatment being tested is called patritumab deruxtecan, also known by its code name MK-1022. This medication is a special type of drug known as a monoclonal antibody, which is designed to target specific proteins in cancer cells. The purpose of the study is to evaluate the safety and effectiveness of this treatment in people with these types of cancers.
Participants in the study will receive the treatment through an intravenous infusion, which means the medication is given directly into a vein. The study will monitor how well the treatment is tolerated and its impact on the cancer. Some participants may receive a placebo, which is a substance with no active medication, to compare the effects. The study will also look at how the cancer responds to the treatment, including how long any positive effects last and whether the cancer progresses or not.
Throughout the study, researchers will collect information on any side effects experienced by participants and how the treatment affects their overall health. The study aims to provide valuable insights into the potential benefits and risks of using patritumab deruxtecan for treating these specific types of gastrointestinal cancers. The results will help determine if this treatment could be a viable option for patients in the future.
