What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
oral vancomycin and oral amoxicillinDrug
In this study, PSC patients will receive an antibiotic preconditioning regimen of oral vancomycin (500 mg liquid twice a day) for 28 days and oral amoxicillin (1000 mg twice a day) for 7 days (during the last 7 days of the oral vancomycin). Following vancomycin and amoxicillin, encapsulated, freeze-dried microbiota preparation (MTP-101C) will be administered - dosed at ≥ 5 x 10^11 bacteria (five capsules) daily for 3 days followed by ≥ 2 x 10^11 bacteria (two capsules) for 11 days - for a total of 14 days of MTP-101C; total of 37 capsules.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing oral vancomycin and oral amoxicillin in people with Primary Sclerosing Cholangitis, run by University of Minnesota at 1 site in United States.
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 7 inclusion and 16 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 20 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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 Amanda Kabage (kabage@umn.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To evaluate safety of MTT in patients with PSC (time frame: 221 days). The study lists 2 primary outcomes in all. 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 20 May 2026.
