Fontan Associated Liver Disease and the Evaluation of Biomarkers for Disease Severity Assessment
United States100 participantsStarted 2022-09-07
Plain-language summary
Background:
In Fontan Associated Liver Disease (FALD), congestion of blood in the liver causes cirrhosis. This condition can cause death. Researchers want to understand what triggers this process and find new treatments for it.
Objective:
To understand how long-term congestion of blood in the liver causes liver scarring that eventually leads to cirrhosis.
Eligibility:
People aged 18 and older who are at risk of developing FALD from the Fontan procedure.
Design:
Participants will be screened with:
Medical history
Physical exam
Blood and urine tests
Liver ultrasound. This uses sound waves to take pictures of the body.
Participants will have an outpatient visit within 12 weeks after screening. Within 24 weeks later, they will have a 3-day hospital stay. About 2 weeks later, they will have a follow-up visit.
Visits will include repeats of the screening tests and:
Heart tests
Stool collection
Questionnaires
MRI of the liver. Participants will lie on a bed that slides in and out of the scanner. They will receive a contrast agent injected into a vein. While in the scanner, they will also have an MRCP to view the bile ducts and the pancreatic duct.
Fibroscan exam. This is an ultrasound that uses a special probe to look at the toughness of the liver.
Upper endoscopy. This uses a thin scope to look inside the upper digestive tract.
Liver biopsy. This will be taken through large vein in the neck or through the chest. Just before the biopsy, participants will have pressure measurements inside their liver. For this, a catheter will be inserted into a neck vein and guided into the liver.

Exclusion criteria
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. Evidence of other forms of liver disease that typically result in cirrhosis.
. Evidence of active Chronic Hepatitis B infection as defined by the presence of hepatitis B surface antigen (HBsAg) in serum and elevated HBV DNA (\>10,000 IU/mL).
. Hepatitis C as defined by the presence of hepatitis C RNA in serum.
. Evidence of other liver disease such as primary sclerosing cholangitis, primary biliary cirrhosis, Wilson s disease, autoimmune hepatitis as defined by either liver histology or laboratory abnormalities.
. Hemochromatosis as defined by presence of 3+ or 4+ stainable iron on liver biopsy or homozygosity for C282Y. Patients with iron saturation indices of \>45% and serum ferritin levels of \>300 ng/ml for men and \>250 ng/ml for women will undergo genetic testing for hemochromatosis.
. Bile duct obstruction as suggested by imaging studies done within the previous six months.
. Active substance abuse, such as alcohol, inhaled or injection drugs within the previous one year (assessed during patient interviews or by patient self-report).
. Evidence of hepatocellular carcinoma; either alpha-fetoprotein (AFP) levels greater than 50 ng/ml (normal \<6.6 ng/ml) and/or ultrasound (or other imaging study) demonstrating a mass suggestive of liver cancer.
