What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is using advanced whole-genome sequencing to find hidden genetic causes of cholestatic liver disease in adults whose condition remains unexplained after standard tests. Researchers will compare the DNA of 60 affected adults to a large group of healthy controls. The goal is to improve diagnosis and understanding of these rare liver disorders.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to better genetic testing for adults with unexplained liver disease, helping doctors diagnose and manage the condition more effectively.
What could go wrong
This is an early-stage observational study with only 60 participants, so findings may not apply to everyone. Genetic sequencing may not find a cause for many patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 60 people

The number the study aims to enrol. It can still change while the study runs.

Started

Nov 2025

Expected to finish

Oct 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 65 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Cases: * Adults, aged \> 18 years with: 1. persistent or intermittent elevations in serum alkaline phosphatase (ALP) or gamma-glutamyltransferase (GGT) for at least six months not explained following standard diagnostic assessment adhering to the guidelines of the European Association for the Study of the Liver (EASL), or with a positive family history of unexplained cholestasis or hepato-biliary cancer, negative to previous genetic tests (targeted panel for PFIC genes or WES); 2. primary sclerosing cholangitis (PSC) with unusual features: small-duct PSC, non-typical radiological findings according to radiological guidelines on PSC, absence of concomitant inflammatory bowel disease, negative to previous genetic tests (targeted panel for PFIC genes or WES) or who didn't perform previous genetic test; 3. primary biliary cholangitis (PBC) without specific anti-mitochondrial antibodies, negative to previous genetic tests (targeted panel for PFIC genes or WES) or who didn't perform previous genetic test. * Signature of informed consent Controls: -Blood donors (age 18-65 years) without clinical signs of liver diseases based on the collected clinical parameters: anthropometric (BMI\>18 and \<25), haematological (Hb, white blood cells, platelets within the reference range), biochemical traits (albumin, bilirubin, AST, ALT, GGT, ALP within the reference range), medical history (negative for chronic or concomitant diseases, including immunological diseases) Exclusion Criteria: Cases: * Patients who do not possess the above inclusion criteria or have at least one of the following exclusion criteria: * an already known genetic diagnosis explaining the clinical phenotype * affected by other causes of liver disease such as viral or autoimmune hepatitis Controls: -Blood donors with clinical signs of liver diseases
