NCT ID NCT07515950
First seen Apr 12, 2026 · Last updated May 12, 2026 · Updated 5 times
Summary
This study will examine stored tumor samples from 244 people diagnosed with biliary tract cancer in the last 15 years. Researchers will measure five specific markers (CLDN18.2, HER2, TROP2, PD-L1, and B7-H4) to see how they relate to patient outcomes. The goal is to better group patients by their cancer type, which could help doctors choose the right targeted therapy in the future. No new treatments or visits are involved—only analysis of existing data and samples.
