Study Summary

This trial is testing a new medication for children with a rare liver disease. The goal is to see if it is safe and effective over the long term.

Who is the study for?
This trial is for children with PFIC, a liver disorder causing severe itching and jaundice. Participants need genetic confirmation of PFIC, have had significant pruritus, weigh at least 5 kg, and can use an eDiary. They must have completed or partially completed a prior A4250 study. Those with episodic PFIC should be experiencing a flare-up.Check my eligibility
What is being tested?
The trial tests the long-term safety and effectiveness of A4250 (odevixibat) in kids with PFIC. It's an open-label extension study meaning all participants receive the drug and are monitored over time to see how well it works and what side effects occur.See study design
What are the potential side effects?
While specific side effects for A4250 aren't listed here, common issues may include gastrointestinal symptoms like diarrhea or abdominal pain due to its effect on bile acids.
