Biliary Interventions in Critically Ill Patients With Secondary Sclerosing Cholangitis (BISCIT)
- Conditions
- Secondary Sclerosing Cholangitis
- Interventions
- Procedure: Endoscopic retrograde cholangiography (ERC)
- Registration Number
- NCT05396755
- Lead Sponsor
- Hannover Medical School
- Brief Summary
This is a randomized, open-label, controlled, parallel group, multicenter clinical trial. Patients with confirmed secondary sclerosing cholangitis (SSC-CIP) will be randomized either in the intervention group undergoing scheduled invasive evaluation of the biliary tract or in the control group treated with non-interventional standard of care to demonstrate that programmed endoscopic therapy compared to a conservative strategy reduces the occurrence of treatment failures.

- Target Recruitment
- 1
Patients have to fulfill all of the following inclusion criteria to be eligible for participation in this study:
-
Men, women*, inter/divers, age ≥18 and ≤ 80 years (conscious or unconscious patients may be included)
-
Signed written informed consent obtained by patient or legal representative in case of unconscious patient
-
Willingness to comply with treatment and follow-up procedures
-
Suspected SSC-CIP = episode of critical illness and intensive care unit treatment > 3 days within last 12 months
-
SSC-CIP is confirmed by ERC, (if the first ERC is performed at baseline, the patient may be considered as screening failure if the diagnosis is not confirmed)
-
Elevation of bilirubin ≥ 2.5 upper limit of normal (ULN) at Screening
-
Elevation of alkaline phosphatase (AP) or gamma-glutamyl-transferase (GGT) > 2.5 ULN or elevation of both at Screening
-
*Women without childbearing potential defined as follows:
-
at least 6 weeks after surgical sterilization by bilateral tubal ligation or bilateral oophorectomy or
-
hysterectomy or uterine agenesis or
-
≥ 50 years and in postmenopausal state > 1 year or
-
< 50 years and in postmenopausal state > 1 year with serum Follicle Stimulating Hormone (FSH) > 40 IU/l and serum estrogen < 30 ng/l or a negative estrogen test, both at screening or
*Women of childbearing potential:
-
who are practicing sexual abstinence (periodic abstinence and withdrawal are not acceptable) or
-
who have sexual relationships with female partners only and/or with sterile male partners or
-
who are sexually active with fertile male partner, have a negative pregnancy test during screening and agree to use reliable methods of contraception (failure rate of < 1% per year) from the time of screening until end of the clinical trial.
-
- Patient is too unstable to undergo ERC
- Inclusion in any other intervention trial within the last 30 days
- Pregnancy or lactation period

Group Intervention Description interventional Endoscopic retrograde cholangiography (ERC) The intervention group undergoes scheduled invasive evaluation of the biliary tract with endoscopic retrograde cholangiography (ERC) with biliary interventions (i.e. therapeutic ERC) every 8 weeks for 6 months.
- Primary Outcome Measures
Name Time Method occurrence of cholangiosepsis (defined by SEPSIS-3 criteria and diagnosis of acute cholangitis according to the Tokyo Guidelines), whatever occurs first. up to week 48 The primary endpoint is the failure rate defined as a composite endpoint consisting of
* occurrence of death or
* necessity of liver transplantation or
* occurrence of cholangiosepsis (defined by SEPSIS-3 criteria and diagnosis of acute cholangitis according to the Tokyo Guidelines), whatever occurs first.necessity of liver transplantation up to week 48 The primary endpoint is the failure rate defined as a composite endpoint consisting of

- Secondary Outcome Measures
Name Time Method Laboratory parameters (creatinine in µmol/L) as change from baseline week 24 Laboratory parameters (bilirubin in µmol/L) as change from baseline week 24 Laboratory parameters (alkaline phosphatase in U/L) as change from baseline week 24 To analyze course of liver function (Model for endstage liver disease score as changes from baseline) week 24 Model for End-Stage Liver Disease (MELD) score 0-40 points with higher values indicating increasing impairment of liver function
Laboratory parameters (aspartate aminotransferase in U/L) as change from baseline week 24 Laboratory parameters (alanine aminotransferase in U/L) as change from baseline week 24 Laboratory parameters (glutamate dehydrogenase in U/L) as change from baseline week 24 Laboratory parameters (c-reactive protein in mg/L) as change from baseline week 24 Laboratory parameters (gamma-glutamyltransferase) as change from baseline week 24 Laboratory parameters (lactate dehydrogenase in U/L) as change from baseline week 24 Occurrence of unplanned Intensive care unit (ICU) admissions (necessity and days free of: intensive care unit care, invasive ventilation, renal replacement therapy, vasopressors within 6 months) week 24 Laboratory parameters (cholinesterase in kU/L) as change from baseline week 24 To analyze the need for anti-infective therapy (antibiotic treatment) in the different study arms week 24 Necessity of treatment with anti-infective medication (= treament with antibiotic oral or intravenously for acute cholangitis) (yes/no)
Occurrence of unplanned hospital admissions (necessity and days free of hospital care within 6 months) week 24
