Using fecal microbiota transplantation to treat antibiotic-resistant infections

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

Phase1; Phase2 Interventional Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT04759001

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.

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.

Who should consider this trial

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

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.

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 performed: 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.
