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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| interventional | Experimental | 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. |
|
| control | No Intervention | The control group receives non-interventional standard of care. |

Inclusion Criteria:
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.
