Official title
A Phase 1/2 Open-Label, Umbrella Platform Design Study of Investigational Agents in Combination With Pembrolizumab (MK-3475) With or Without Chemotherapy in Participants With 1L Locally Advanced Unresectable/Metastatic Esophageal Cancer: KEYMAKER-U06 Substudy 06E
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Researchers are looking for new ways to treat esophageal squamous cell carcinoma (ESCC). ESCC is a type of cancer that starts in certain cells that line the esophagus. The esophagus is the tube that connects the throat to the stomach. This study will look at ESCC that is either locally advanced unresectable, which means it has spread into tissue near where it started and cannot be completely removed by surgery, or metastatic, which means it has spread to other body parts. Available treatments for these types of ESCC include pembrolizumab and chemotherapy. Pembrolizumab is an immunotherapy, which is a treatment that helps the immune system fight cancer. Chemotherapy is medicine that destroys cancer cells or stops them from growing. Researchers want to learn about giving pembrolizumab and investigational agents, with or without chemotherapy to treat ESCC. Ifinatamab deruxtecan (I-DXd), is an antibody-drug conjugate (ADC). An ADC attaches to a protein on cancer cells and delivers treatment to destroy those cells. The main goal of this study is to learn about the safety of investigational agents and pembrolizumab with or without chemotherapy and if people tolerate them. Researchers also want to learn how cancer responds (gets smaller or goes away) to the study treatments.
