Trial summary

About 1/3 of patients with primary biliary cholangitis (PBC) exhibit moderate to severe interface hepatitis, and this group of patients have poor response to UDCA treatment. However, as it is not yet sufficient to diagnose autoimmune hepatitis or overlap syndrome, it is difficult to initiate immunosuppressive therapy… Read more about this study

About this study

About 1/3 of patients with primary biliary cholangitis (PBC) exhibit moderate to severe interface hepatitis, and this group of patients have poor response to UDCA treatment. However, as it is not yet sufficient to diagnose autoimmune hepatitis or overlap syndrome, it is difficult to initiate immunosuppressive therapy such as steroids according to current guidelines. The aim of this study is to explore whether PBC patients with moderate to severe interfacial inflammation can benefit from UDCA combined with prednisone therapy, and its treatment safety.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PrednisoneDrug

    Prednisone 30-40 mg/day, at 7am in the morning, gradually reduced after 1 month (5mg every 7-14 days) to 5-10 mg for maintenance treatment

  • UDCA (Ursodeoxycholic acid)Drug

    13-15 mg/kg/day

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of patients with biochemical response

    Alkaline Phosphatase \&lt; 1.67*ULN

    Measured: 1 year

Secondary outcomes (2)
  1. Assessment of the pruritus and fatigue

    Change From Baseline in Fatigue and Pruritus as Assessed by Visual Analogue Scale (VAS) Total Score for Fatigue and Pruritus. (0-10, higher scires mean a worse outcome)

    Measured: 1, 3, 6, 9, and 12 months

  2. Survival without transplantation and hepatic impairment

    Occurrence of ascites, variceal bleeding, hepatic encephalopathy, liver-transplantation, or death.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Prednisone and UDCA (Ursodeoxycholic acid) in people with Primary Biliary Cholangitis (PBC), run by Han Ying at 2 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 28 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of patients with biochemical response (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Nov 2025.
