Comparing UDCA and Corticosteroids in Immunotherapy Induced Cholestatic Hepatitis

Phase 2Not Yet RecruitingNCT07378761

University Hospital, Montpellier94 enrolled

Overview

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.

Interventions

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.

Outcomes

Primary Outcomes

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.

Time frame: 21 days after randomization

Secondary Outcomes

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.

Time frame: 6 Months after randomization

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)

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

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)

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

Resumption of immunotherapy

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

Time frame: Within 12 months after randomization
