Using faecal microbiota transplantation to eliminate multidrug resistant organisms in the intestine

The Effect of Faecal Microbiota Transplantation (FMT) on Eradication of Multidrug Resistant Organisms (MRO) in Intestinal Carriers - a Multicentre, Randomized, Double-blinded and Placebo-controlled Study

Not applicable Interventional Hvidovre University Hospital · NCT05742074

This study is testing if a treatment using healthy gut bacteria can help people who carry hard-to-treat germs in their intestines get rid of them.

What this trial studies

This clinical trial investigates the effectiveness of faecal microbiota transplantation (FMT) in eradicating multidrug resistant organisms (MRO) from the intestines of carriers. It is a randomized, double-blinded, and placebo-controlled study involving 80 participants who will receive either FMT or a placebo. Participants will consume 25-30 capsules of FMT or placebo over one or three days, and their intestinal microbiome will be analyzed through rectal swabs and faecal samples at baseline and 16 weeks post-treatment. The goal is to determine if FMT can induce resistance to MRO colonization, potentially preventing serious infections that are difficult to treat.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who are positive for multidrug resistant organisms in their intestines.

Not a fit: Patients currently experiencing invasive infections with multidrug resistant organisms or those with severe immune deficiencies may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of invasive infections caused by multidrug resistant organisms.

How similar studies have performed: Previous studies have shown promise in using faecal microbiota transplantation for various conditions, but the specific application for multidrug resistant organisms is still being explored.
