Summary

This Phase 3 study tests odevixibat, a daily pill, in 254 children with biliary atresia who recently had Kasai surgery. The goal is to see if the drug can prevent the need for a liver transplant or death. Children take either odevixibat or a placebo for up to 2 years, and researchers track who needs a transplant or experiences serious liver events.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
odevixibat
What this could lead to
If successful, odevixibat could help children with biliary atresia avoid or delay liver transplant, improving survival without a new organ.
What could go wrong
This is a Phase 3 trial, but results are not yet available. The drug may not work better than placebo, and side effects like diarrhea or liver issues are possible.
