New drug aims to shrink hard-to-treat GI tumors
NCT ID NCT06864169
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new medicine called raludotatug deruxtecan in about 160 adults with advanced gastrointestinal cancers (pancreatic, bile duct, gallbladder, colorectal, stomach, or gastroesophageal junction). The drug is designed to attach to cancer cells and deliver a treatment that destroys them. The main goal is to see if the tumors shrink or disappear. Participants will be monitored for side effects and how long the response lasts.
