The Effect of Faecal Microbiota Transplantation (FMT) on Eradication of Multidrug Resistant Organisms (MRO) in Intestinal Carriers (FEMRO)

April 14, 2026 updated by: Andreas Munk Petersen, Hvidovre University Hospital

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

The aim of this study is to investigate the effect of faecal microbiota transplantation (FMT) on eradication of multidrug resistant organisms (MRO) in the intestine. Ultimately, it would be possible to prevent invasive infections with MRO that are difficult to treat and require last-resort antibiotics. The investigators hypothesize that FMT induce intestinal resistance towards colonization with MRO e.g. Vancomycin resistant Enterococcus Faecium (VRE), carbapenemase-producing Enterobacterales (CPE) and extended-spectrum beta-lactamase producing Enterobacterales (ESBL-E).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study is designed as a randomized, double-blinded and placebo-controlled clinical trial. The participants (n = 80) will be randomized 1:1 to FMT or placebo. FMT or placebo consist of 25-30 capsules which need to be consumed on one day or alternatively consumed over three consecutive days, if one day is unacceptable to the participant. At baseline, eight weeks, and 16 weeks rectal swabs for PCR and culture will be taken. Regarding VRE and CPO, there are specific PCRs followed by confirmatory culture, whereas ESBL-E is detected by culture of rectal swab. Furthermore, participants will be asked to deliver faecal samples as well at baseline and 16 weeks post FMT to examine changes in the intestinal microbiome.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 110 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of participants with MRO clearance
Time Frame: 8 weeks
Number of participants with MRO clearance after eight weeks. This will be measured on rectal samples that will undergo PCR/culture for ESBL, VRE and CPO. The results from the test will be positive or negative.
8 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of participants with MRO clearance
Time Frame: 16 weeks
Number of participants with negative PCR for MRO on rectal swab and faecal culture negative for MRO after 16 weeks. This will be measured on rectal samples that will undergo PCR/culture for ESBL, VRE and CPO. The result from the test will be positive or negative
16 weeks
Number of participants with adverse events.
Time Frame: 8 weeks, 16 weeks and 6 months.
