Who may be able to join

  • Diagnosis of PSC established by alkaline phosphatase >1.5 times and/or two fold elevation of liver transaminases (AST and/or ALT) for at least 6 months duration.
  • Cholangiography demonstrating intrahepatic and/or extrahepatic biliary obstruction, beading, or narrowing consistent with PSC.

About this study

The purpose of this study is to determine whether Vancomycin or Metronidazole is safe and beneficial in the treatment of Primary Sclerosing Cholangitis.

Read the detailed description

In this protocol, we propose the assessment of potential beneficial effects of the antibiotics vancomycin and metronidazole on liver biochemistries, liver related symptoms and Mayo risk score in patients with PSC. The patients will be randomized into four groups of ten patients: one group will receive low dose vancomycin, one group will receive high dose vancomycin, one group will receive low dose metronidazole and one group will receive high dose metronidazole. Each group will be treated for three months.

Medical subject headings
Cholangitis, Sclerosing

What is being measured

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

  1. Change From Baseline in Alkaline Phosphatase Following 12 Weeks of Treatment

    Measured: baseline, 12 weeks

Secondary outcomes (3)
  1. Change From Baseline in Total Bilirubin Following 12 Weeks Treatment

    Measured: baseline, 12 weeks

  2. Change From Baseline in Mayo PSC Risk Score Following 12 Weeks of Treatment

    The Mayo PSC risk score was calculated for each patient at baseline and at 12 weeks, where Risk = 0.03 (age [years]) + 0.54 Ln (total bilirubin [mg/dL]) + 0.54 Ln (AST [IU/L]) + 1.24 (variceal bleeding) - 0.84 (albumin [g/dL]). There is no range, minimum, or maximum value but greater values indicate worse disease.

    Measured: baseline, 12 weeks

  3. Change From Baseline in C-Reactive Protein Following 12 Weeks of Treatment

    Measured: baseline, 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Vancomycin and Metronidazole in people with Primary Sclerosing Cholangitis, run by Mayo Clinic 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 5 inclusion and 8 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: finished, as of the sponsor's last update on 19 Sep 2013. 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?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Sep 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Alkaline Phosphatase Following 12 Weeks of Treatment (time frame: baseline, 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01085760, which also lists 1 linked publication.

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 19 Sep 2013.
