About this study

Official title: Efficacy of Ursodeoxycholic Acid Versus Corticosteroids for the Treatment of Cholestatic Hepatitis Secondary to Immunotherapy: A Multicenter, Controlled, Randomized, Open Trial

The clinical trial aims to compare the effectiveness of ursodeoxycholic acid (UDCA) to corticosteroids in treating cholestatic hepatitis induced by immune checkpoint inhibitors (ICIs) over a 21-day period.

The trial presents a detailed scientific justification for comparing UDCA to corticosteroids, describing the treatment and detailing the follow-up procedures. It hypothesizes that UDCA could be superior to corticosteroids for treating ICI-related cholestatic hepatitis, based on its established use in primary biliary cholangitis and a favorable tolerance profile compared to corticosteroids.

What participants receive

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

  • UDCA (Ursodeoxycholic acid)Drug

    Ursodeoxycholic acid (UDCA) will be administered orally at an initial dose of 13-15 mg/kg/day, divided into two daily doses. After assessment of the primary endpoint at Day 21, UDCA will be continued for a total treatment duration of 6 months. In case of absence of treatment response, defined as no decrease of alkaline phosphatase and/or gamma-glutamyl transferase levels of at least 25% compared with baseline, corticosteroids which represent the reference treatment, will be added at a dose of 0.5-1 mg/kg.

  • Corticosteroids (Reference Treatment)Drug

    Corticosteroids will be administered orally at a dose of 0.5-1 mg/kg/day for 21 days, followed by a tapering schedule of 10 mg per week until treatment discontinuation. At Day 21, if there is no adequate response (defined as less than 25% decrease in alkaline phosphatase and/or gamma-glutamyl transferase from baseline), the corticosteroid taper will continue and ursodeoxycholic acid (UDCA) will be added at a dose of 13-15 mg/kg/day.

Study groups in NCT07378761
Study groupRoleWhat they receive
Experimental armExperimentalPatients randomized to the experimental arm will receive ursodeoxycholic acid (UDCA) as initial treatment for hepatitis. After evaluation of the primary endpoint at Day 21, UDCA treatment will be continued for a total duration of 6 months. In case of lack of response to UDCA, patients will continue UDCA and will additionally receive corticosteroids which represent the reference treatment.
Receives: Drug: UDCA (Ursodeoxycholic acid)
Control armActive comparatorPatients randomized to the control arm will receive the reference treatment, corticosteroids. Corticosteroids will be given at a dose of 0.5-1 mg/kg/day for 21 days, followed by tapering in weekly steps of 10 mg until treatment discontinuation. At Day 21, in case of lack of treatment response, defined as no decrease of alkaline phosphatase and/or gamma-glutamyl transferase levels of at least 25% compared with baseline, corticosteroid tapering will continue, and ursodeoxycholic acid (UDCA) will be added at a dose of 13-15 mg/kg/day.

What is being measured

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

  1. Improvement of at least 25% in liver function tests on day 21 after randomization

    The rate of patients showing an improvement of at least 25% in liver function tests (alkaline phosphatase and/or gamma-GT) on Day 21 after randomization.

    Measured: 21 days after randomization

Secondary outcomes (4)
  1. Rate of Hepatitis Resolution at 6 Months

    Rate of patients with resolution of hepatitis, defined as hepatitis grade ≤ 1 according to the current National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), at 6 months after randomization.

    Measured: 6 Months after randomization

  2. Time to Hepatitis Resolution

    Time to hepatitis resolution, defined as the time from the date of randomization to the date of hepatitis resolution (grade ≤ 1). Hepatitis severity will be graded according to the current National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE)

    Measured: From Randomization to end of follow-up at 12 months

  3. Tolerance to UDCA and/or Corticosteroids

    Tolerance to ursodeoxycholic acid (UDCA) and/or corticosteroids will be evaluated through the assessment of adverse events. Adverse events will be collected throughout the study and graded according to the current National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE)

    Measured: From treatment initiation following the randomization to end of follow-up at 12 months

  4. Resumption of immunotherapy

    Rate of patients in whom resumption of immunotherapy was possible after hepatitis within 12 months after randomization

    Measured: Within 12 months after randomization

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing UDCA (Ursodeoxycholic acid) and Corticosteroids (Reference Treatment) in people with Immune-Mediated Cholestasis, run by University Hospital, Montpellier at 6 sites in France.

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 4 inclusion and 15 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: looking for participants now, as of the sponsor's last update on 9 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in France. 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 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.

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?

Contact Dr. MEUNIER (+33467330224, lucy.meunier@chu-montpellier.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Improvement of at least 25% in liver function tests on day 21 after randomization (time frame: 21 days after randomization). 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 9 Sep 2026.
