Using fecal microbiota transplantation to eliminate drug-resistant bacteria from the gut

Efficacy and Mechanisms of Fecal Microbiota Transplantation to Eradicate Intestinal Colonization by Carbapenem-resistant Enterobacteriaceae

Phase1; Phase2 Interventional Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT05791396

This study is testing whether a treatment called fecal microbiota transplantation can help people get rid of tough drug-resistant bacteria in their gut.

What this trial studies

This clinical trial investigates the use of fecal microbiota transplantation (FMT) to eradicate intestinal colonization by carbapenem-resistant Enterobacteriaceae (CRE). The study aims to evaluate the efficacy of FMT from donors with limited antibiotic resistance genes in a randomized controlled setting. Participants will be monitored for clinical efficacy and the clearance of antibiotic resistance genes, with the goal of restoring healthy gut microbiota to combat multi-drug-resistant bacteria. The trial is designed to provide established evidence for FMT as a treatment option for infections caused by these resistant bacteria.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old diagnosed with carbapenem-resistant Enterobacteriaceae within the last 15 days.

Not a fit: Patients with active chronic gastrointestinal disorders, previous colorectal surgery, or major comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel treatment option for patients suffering from infections caused by multi-drug-resistant bacteria.

How similar studies have performed: Preliminary nonrandomized evidence suggests that fecal microbiota transplantation could be effective in eradicating multi-drug-resistant bacteria, but this specific approach is still being evaluated.
