New hope for rare bile duct cancer: targeted pill shows promise in Late-Stage trial
NCT ID NCT05876754
First seen Jun 26, 2026 · Last updated Jul 31, 2026 · Updated 2 times
Summary
This study tests a daily pill called ivosidenib in 220 adults with advanced bile duct cancer that has a specific IDH1 gene mutation and has not responded to prior treatment. The goal is to confirm the drug's safety and effectiveness. Participants take the tablet once daily in 28-day cycles as long as they benefit and tolerate it.
