Phase 3
Active, not recruiting
Conditions
Biliary Atresia
Interventions
Drug: Placebo
Registration Number
NCT04336722
Lead Sponsor
Albireo, an Ipsen Company
Brief Summary

Double-blind, randomized, placebo-controlled, Phase 3 study to investigate the efficacy and safety of odevixibat compared to placebo in children with biliary atresia who have undergone a Kasai hepatoportoenterostomy.

All
Target Recruitment
254
Inclusion Criteria
  • A male or female patient with a clinical diagnosis of BA
  • Age at Kasai HPE ≤90 days
  • Eligible to start study treatment within 3 weeks post-Kasai HPE

Key

Exclusion Criteria
  • Patients with intractable ascites
  • Ileal resection surgery
  • ALT ≥10× upper limit of normal (ULN) at screening
  • Patients reliant only on total parenteral nutrition, or not able to take study medication orally, at randomization
  • Acute ascending cholangitis (patients may be randomized after resolution of acute ascending cholangitis)
  • Choledochal cystic disease
  • INR >1.6 (the patient may be treated with Vitamin K intravenously; sample may be redrawn and if INR is ≤1.6 at resampling the patient may be randomized)
  • Any other conditions or abnormalities, including congenital abnormalities, major cardiac surgery, hepatic, biliary, or GI disease which, in the opinion of the Investigator or Medical Monitor, may compromise the safety of the patient, the integrity of study results, or patient compliance with study requirements
  • Weight <3.5kg at randomization

Percentage of participants experiencing Adverse Events (AEs) and Serious Adverse Events (SAEs)From baseline to Week 104

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.

Percentage of participants with clinically significant changes in Physical ExaminationFrom baseline to Week 104

Percentage of participants with clinically significant changes in physical examination findings will be reported. The clinical significance will be graded by the investigator.

Percentage of participants with clinically significant changes in Laboratory Parameters (blood chemistry, hematology and coagulation)From baseline to Week 104

Percentage of participants with clinically significant change in laboratory parameters (blood chemistry, hematology and coagulation) will be reported. The clinical significance will be decided by the investigator.

Percentage of participants with clinically significant changes in Abdominal Ultrasound findingsFrom baseline to Week 26 and Week 104

Percentage of participants with clinically significant change in Abdominal Ultrasound findings will be reported. The clinical significance will be decided by the investigator.

Proportion of patients with liver transplantFrom baseline to Week 104

Proportion of patients who are alive and have not undergone a liver transplant

Total bilirubin levelsFrom baseline to Weeks 13, 26, 52 and 104

Total bilirubin level after 13, 26, 52, and 104 weeks of study treatment
