New drug shows promise for rare childhood liver disease
NCT ID NCT03566238
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a drug called odevixibat (A4250) in 62 children with progressive familial intrahepatic cholestasis (PFIC) types 1 and 2, a rare liver disease that causes severe itching and bile buildup. The drug works by blocking the reabsorption of bile acids in the gut. The goal was to see if it could lower bile acid levels and reduce itching compared to a placebo. Results could lead to a new treatment option for these children.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- odevixibat (A4250)
- What this could lead to
- If successful, odevixibat could become a new treatment to reduce bile acid buildup and severe itching in children with PFIC, potentially delaying or avoiding the need for liver transplant.
- What could go wrong
- This is a relatively small Phase 3 trial (62 children), and the drug may not work for all types of PFIC. Long-term safety and effectiveness are still being studied.
