Summary

This trial is testing a medication called odevixibat in children with a liver condition called Biliary Atresia. The medication aims to lower bile acids in the liver and intestines to help protect the liver and improve symptoms. Children who completed a previous related study can join this study to see if the medication is safe and effective over time.

Who is the study for?
This trial is for children with Biliary Atresia who completed a previous 104-week study of Odevixibat. They must have consent from a caregiver and cannot join if they're allergic to Odevixibat, need an imminent liver transplant, were non-compliant in the prior study, or have conditions that may risk their safety or study participation.
What is being tested?
The trial tests the long-term effects and safety of Odevixibat on children with Biliary Atresia. It's an extension of a prior study where participants continue to receive this medication under open-label conditions, meaning both researchers and participants know what treatment is being given.
What are the potential side effects?
While specific side effects are not listed here, generally speaking, medications like Odevixibat could potentially cause digestive issues, allergic reactions or impact liver function. The exact side effects will be monitored closely throughout the trial.
