Study summary

This study is a biobank of specimens and clinical data for use in current and future research to better understand the cholestatic liver diseases primary biliary cirrhosis/cholangitis (PBC) and primary sclerosing cholangitis (PSC).

Read the detailed description

This study is a biobank of specimens and clinical data for use in current and future research to better understand the cholestatic liver diseases primary biliary cirrhosis/cholangitis (PBC) and primary sclerosing cholangitis (PSC).

Blood, saliva, stool, and urine samples will be collected periodically during patient visits, mail-home kit (collected locally), or via remote phlebotomy at a place directed by the subject. Bile and bile duct cells will be collected during clinically necessary Endoscopic Retrograde Cholangiopancreatography (ERCP) procedures being performed at Mayo Clinic for clinical reasons. Anticipated research will focus on multi-omics assessments of biospecimens to better define how these diseases start and progress in order to develop novel tests for early detection of complication and better disease prognostication.

Study population

Patients with PBC, PSC, controls without liver disease, and with other chronic liver disease without history of PBC or PSC seen or followed at Mayo Clinic will be invited to participate in this study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

PSC

  • Patients diagnosed with PSC and who are between the age of 18 and 85 at time of enrollment in the study.
  • The diagnosis of PSC will be based on standard PSC criteria including clinical and biochemical evidence of chronic cholestasis of at least six months duration, positive cholangiographic findings, and compatible liver if available.
  • Patients with PSC who have undergone orthotopic liver transplantation will be offered enrollment except for collection of bile - please see below under Exclusion Criteria.
  • Women with PSC of and pregnant women will be offered enrollment because there is no risk to an unborn child in this investigation.

PBC

  • Patients diagnosed with PBC and who are between the age of 18 and 85 at time of enrollment in the study.
  • The diagnosis of PBC will be based on standard PBC criteria including clinical and biochemical evidence of chronic cholestasis of at least six month duration, positive anti-mitochondrial antibodies in serum and compatible liver biopsies, if available.
  • Patients with PBC who have undergone orthotopic liver transplantation will be offered enrollment except for collection of bile - please see below under Exclusion Criteria.
  • Women with PBC of childbearing potential and pregnant women will be offered enrollment because there is no risk to an unborn child in this investigation.

Controls

  • Controls without history of PBC, PSC, or evidence of other chronic liver disease of either gender that participate in this study will be between the ages of 18 and 85.

Liver Disease Controls

  • Patients without history of PBC or PSC but do have evidence of other chronic liver disease of either gender will be offered participation in this study if between the ages of 18 and 85.

Exclusion criteria

Exclusion Criteria (all subjects):

  • PBC or PSC patients with known and overlapping other chronic liver diseases
  • Patients unable to provide
  • Prisoners and institutionalized individuals

Exclusion Criteria (for bile collection during ERCP)

  • PSC with orthotopic liver transplantation
  • History of Roux en Y
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

The record gives a start of Jan 2017, a primary completion of Jan 2050 and a completion of Jan 2050. It does not say whether these dates are actual or estimated.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 17, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
