Using fecal microbiota transplantation to treat antibiotic-resistant infections

Official title: Faecal Microbiota Transplantation to Eradicate Gut Colonisation From Carbapenem-resistant Enterobacteriaceae: a Randomised Controlled Trial

Run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT04759001 · Data updated 2026-11-12

This study is testing whether a treatment using healthy gut bacteria from donors can help people get rid of hard-to-treat infections caused by antibiotic-resistant germs.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 years or older who are currently colonized with carbapenem-resistant Enterobacteriaceae.

Probably not a fit

Patients with other gastrointestinal infections, active gastrointestinal disorders, or those who have recently altered their gut microbiota through medication may not benefit from this study.

What this trial studies

This clinical trial investigates the use of fecal microbiota transplantation (FMT) to eliminate carbapenem-resistant Enterobacteriaceae (CRE) from the gut. The study aims to compare the effectiveness of donor FMT against a placebo FMT in patients who are colonized with these multi-drug resistant bacteria. By restoring healthy gut microbiota, the trial seeks to enhance colonization resistance and reduce the risk of infections associated with CRE. The study is designed as a randomized controlled trial to provide robust evidence on the efficacy of this approach.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the prevalence of multi-drug resistant infections in patients, improving overall health outcomes.

How similar studies have gone: While there is limited evidence from case reports and a single early-terminated trial, the potential of FMT for treating multi-drug resistant bacteria remains largely untested in larger, well-designed studies.
