Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 105 who have tested positive for drug-resistant Enterobacteriaceae.

Probably not a fit

Patients currently receiving antibiotic treatment or those in intensive care may not benefit from this study.

What this trial studies

This clinical trial investigates the use of fecal microbiota transplantation (FMT) as a method to decolonize patients carrying multi-drug resistant Gram-negative bacteria (MDR-GNB). The study aims to assess the efficacy of FMT capsules compared to placebo in eradicating these harmful bacteria from the gut microbiome. Given the rising threat of antibiotic resistance, this approach could provide a novel solution to prevent infections and reduce the spread of MDR-GNB in healthcare settings and communities. Participants will include adults with documented MDR-GNB colonization or infection, and healthy volunteers will provide fecal samples for transplantation.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the incidence of infections caused by drug-resistant bacteria, improving patient outcomes and public health.

How similar studies have gone: Previous studies have shown promising results for fecal microbiota transplantation in decolonizing drug-resistant bacteria, indicating potential success for this approach.
