Investigating the effects of oral vancomycin on liver disease in adults with primary sclerosing cholangitis.

A Prospective, Randomized, Multi-centered, Placebo-controlled Clinical Trial of Oral Vancomycin in Adults with Primary Sclerosing Cholangitis

NIH-funded research Mayo Clinic Arizona · NIH-10474350

This study is looking for adults with primary sclerosing cholangitis (PSC) to see if taking an oral medication called vancomycin can help reduce liver inflammation and improve liver function, which could lead to better treatment options for this serious condition.

What this research studies

This research focuses on adults diagnosed with primary sclerosing cholangitis (PSC), a serious liver condition that can lead to severe complications. Participants will be randomly assigned to receive either oral vancomycin or a placebo to assess its effectiveness in reducing liver inflammation and improving liver function. The study aims to gather data on how this treatment impacts the progression of PSC and its associated symptoms. By participating, patients will contribute to understanding a potential new therapy for a condition that currently has no proven medical treatment.

Who could benefit from this research

Good fit: Ideal candidates for this research are adults diagnosed with primary sclerosing cholangitis, particularly those experiencing significant liver-related symptoms.

Not a fit: Patients with other liver diseases or those who have already undergone liver transplantation may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a new treatment option that may slow the progression of primary sclerosing cholangitis and improve patients' quality of life.

How similar studies have performed: Previous open-label trials have shown promising results with oral vancomycin in PSC patients, suggesting that this approach may be effective.
