The BOLD research study is the first pivotal Phase 3 study to evaluate the safety and efficacy of odevixibat in babies with biliary atresia who have undergone a Kasai hepatoportoenterostomy (HPE).
A clinical trial is a scientific study where researchers learn if and how a medication works. The BOLD study has been initiated by Albireo Pharma, a clinical-stage biopharmaceutical company focused on rare pediatric liver diseases and disorders.
What is biliary atresia?
Biliary atresia is a rare pediatric liver disease where damaged or absent bile ducts outside the liver result in bile and bile acids being trapped inside the liver. This may result in cirrhosis, and even liver failure. Symptoms typically develop two to six weeks after birth.
There are no approved medications for biliary atresia.
What is the BOLD study?
The BOLD (Biliary Atresia and the Use of Odevixibat in Treating Liver Disease) study is the first pivotal Phase 3 clinical trial for infants with biliary atresia. During a two-year period, the double-blind, randomized study will investigate how well and safely the investigational* drug odevixibat works. The trial will evaluate if a child with biliary atresia who has undergone a Kasai HPE can delay or avoid liver transplant by taking odevixibat.
The results from the trial will be shared with regulatory authorities that assess if odevixibat can be approved to treat biliary atresia.
*The term "investigational" means that odevixibat is not approved for use in biliary atresia or any other conditions anywhere in the world.
What is odevixibat?
The investigational medicine of the BOLD study, odevixibat, is a potent, non-systemic ileal bile acid transport inhibitor (IBATi) designed to treat rare pediatric cholestatic liver diseases such as biliary atresia. Odevixibat is a once-daily oral medication which may be emptied into breastmilk, formula, or certain soft foods.
Babies with a clinical diagnosis of biliary atresia, aged 90 days or less at the time of Kasai HPE, and who are able to start the study treatment within 3 weeks of their Kasai, may be eligible to participate.
There is a very small window of time where babies may be eligible, so it is important to talk to your baby's doctor right away.

Biliary atresia is a rare pediatric liver disease that occurs in an estimated one out of every 15,000-20,000 live births in the United States and European Union. Though rare, it is the most common pediatric cholestatic liver disease and the leading cause of pediatric liver transplant across all diseases.
Symptoms typically develop about two to six weeks after birth due to damaged or missing bile ducts. With no pathway out of the liver, bile builds up and starts to destroy liver cells, which leads to scarring of the liver, called cirrhosis, and possibly liver failure.
There are currently no approved medications for biliary atresia. A Kasai HPE procedure can help reestablish bile flow from the liver to the gallbladder.
BOLD is a double-blind, randomized, placebo-controlled study.
- Double-blind: trial participants, their families, and clinicians involved in the research study do not know if a participant is taking the investigation medication or a placebo.
- Placebo: looks like the study drug but does not contain any of the medication. Researchers compare results from patients taking a placebo with those taking the study drug to see if the study drug works better.
- Randomized: investigators randomly assign half the trial participants to the experimental group, which receives the drug, and the other half to the control group, which receives the placebo.
A clinical trial is usually described by the phase it is in. Each phase usually has a different purpose, a larger group of participants, and a longer study period.
- Phase 1: Basic safety. Tests an experimental treatment on a small group of often healthy people to understand its safety and potential side effects, as well as to help find the correct dosage.
- Phase 2: Effectiveness. Focuses on whether the medicine works on a larger group of people who have a specific disease or condition. Researchers continue to study safety, including short-term side effects. This phase can last several years.
- Phase 3: Wider safety and effectiveness. Gathers more information about safety and effectiveness by studying much larger and more varied groups of people, often with different medication doses. A treatment may also be used in combination with other medications.
- Upon completion of Phase 3, a company can submit the investigational medicine for review by a regulatory body such as the Food & Drug Administration (FDA) in the United States. Once that body reviews the data and agrees that the Phase 3 trial had positive results, it may approve the investigational medicine for use by patients within the territory it governs.
- Phase 4: Long-term effects. After the FDA approves a medication for use, this phase examines a product in the largest set of patients to gauge long-term effectiveness of the treatment or intervention.
