Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study is testing whether a blood test that looks for tumor DNA (ctDNA) can be as good as a tissue biopsy for finding genetic changes in advanced bile duct cancer. Researchers will enroll 200 adults with advanced biliary tract cancer across multiple hospitals in Korea. The goal is to see if this simpler, faster test can help doctors choose the right targeted therapy without needing a tissue sample.
