A Phase 2 Nonrandomized, Open-label, Multisite Study to Evaluate the Safety and Efficacy of Raludotatug Deruxtecan in Participants With Gastrointestinal Cancers
- Study HIC#:2000039419
- Last Updated:07/09/2025
Researchers are looking for new ways to treat certain types of advanced gastrointestinal (GI) cancers. The study medicine raludotatug deruxtecan (also called MK-5909, R-DXd, or DS-6000a) is a type of medicine called 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 if the cancer responds to treatment (gets smaller or goes away).
