Profiling Fecal Samples for Selection of Donors of Feces (PROFIT)

June 30, 2023 updated by: Assistance Publique - Hôpitaux de Paris

Profiling Fecal Samples to Optimize Selection of Stool Donors for Fecal Microbiota Transplantation

Fecal microbiota transplantation (FMT) represents a promising therapeutic in numerous clinical situations associated with dysbiosis. Today, this procedure is recommended in patients with recurrent Clostridioides difficile infections but beneficial effects of FMT have also been described in other diseases associated with intestinal dysbiosis …. A donor effect which could be related to the inter-individual variability of microbiota and microbiome leading to specific metabolic capacities may influence the efficacy of the procedure.

Detailed Description

Fecal microbiota transplantation (FMT) represents a promising therapeutic in numerous clinical situations associated with dysbiosis. Today, this procedure is recommended in patients with recurrent Clostridioides difficile infections but beneficial effects of FMT have also been described in other diseases associated with intestinal dysbiosis …. A donor effect which could be related to the inter-individual variability of microbiota and microbiome leading to specific metabolic capacities may influence the efficacy of the procedure. The aim of our study is to measure fecal biochemical, microbial and immunological parameters that are known to influence gut homeostasis in a group of 40 healthy donors to establish a referential profile of human stools to optimize donor profiling, beyond the infectious parameters, to increase the success rate of FMT.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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).

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
Dosage of fecal samples with search for differentiated fecal profiles.
Time Frame: At 12 months

16S genomic analysis of microbiota will be performed for the evaluation of alpha and beta diversities of microbiota.

Results will be aggregated to define differentiated faecal profiles in healthy volunteers.
At 12 months

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
Dosage of fecal biomarkers with search for differentiated fecal profiles.
Time Frame: At 12 months
Fecal biomarkers such as calprotectin will be dosed. Results will be aggregated to define differentiated faecal profiles in healthy volunteers.

Quantification of colonic inflammation in mouse model.
Time Frame: At 15 months

The quantification of colonic inflammation by myeloperoxidase assay using a sandwich ELISA enzyme-linked immunosorbent assay.

Mouse model : authorization APAFlS#7600-20l60620l6336853 v3
