An Open-label Extension Study to Evaluate Long-term Efficacy and Safety of Odevixibat in Children With Biliary Atresia
- Registration Number
- NCT05426733
- Lead Sponsor
- Albireo, an Ipsen Company
- Brief Summary
An Open-label Extension Study to Evaluate Long-term Efficacy and Safety of Odevixibat (A4250) in Children with Biliary Atresia
- Detailed Description
This is a Phase 3, multi-center, open-label extension study to evaluate the long-term efficacy and safety of odevixibat in patients with Biliary Atresia (BA). Patients who completed treatment in the A4250-011 BOLD study and meet eligibility criteria for Study A4250-016 (BOLD-EXT) can participate. The duration of the treatment period is 104 weeks, followed by a 4-week Safety Follow-up Period. Patients who wish to continue receiving odevixibat after 104 weeks can remain on treatment in the optional extension period (OEP).
Up to 180 patients will be enrolled at approximately 70 sites in the North America, Europe, the Middle East and Asia-Pacific.

Group Intervention Description Odevixibat (A4250) Odevixibat Capsules for oral administration once daily for 104 weeks.
- Primary Outcome Measures
Name Time Method Proportion of patients who are alive and have not undergone liver transplant From baseline to Week 104
- Secondary Outcome Measures
Name Time Method Change in Fibrosis-4 (Fib-4) score From baseline to Week 104 The Fib-4 score provides an estimate of the amount of scarring (fibrosis) in the liver. A higher score indicates a greater amount of scarring in the liver.
* A score \< 1.45 indicates a low likelihood of fibrosis
* A score \> 3.25 indicates a higher probability of fibrosisChange in height From Baseline to Weeks 26, 52, 78 and 104 Change in serum bile acids From Baseline to Weeks 26, 52, 78, and 104 Change in mid-arm circumference From Baseline to Weeks 26, 52, 78 and 104 Measure of growth
Change in pediatric end-stage liver disease (PELD) score From Baseline to Weeks 26, 52, 78 and 104 The PELD (pediatric end-stage liver disease) score is a measure of disease severity. PELD scores can range from a negative value (such as -10) to high numbers (such as 45). A higher score indicates more severe disease.
Change in aspartate aminotransferase (AST) to platelet ratio index (APRI) score From baseline to Week 104 The APRI (aspartate aminotransferase to platelet ratio index) score estimates the severity of liver fibrosis. A higher score indicates a greater amount of scarring (fibrosis) in the liver.
* A score ≤ 0.5 indicates a low likelihood of fibrosis
* A score ≥ 1.5 indicates a higher probability of fibrosisTime to onset of any sentinel events From Baseline to Week 104 Change in weight From Baseline to Weeks 26, 52, 78 and 104
