For the first time in the world, the objective of this study is to evaluate on healthy volunteers, an innovative medical device for the capture of intestinal liquid.This medical device is not yet CE marked.
This medical device consists of a standard pill made of 3 capsules for the collection of intestinal microbiota. The pill is ingested by the volunteer and multi-omics analysis will be performed on intestinal fluid samples from the capsules and also on faeces. First in man, involving a medical device, prospective, monocentric, not randomized, not controlled and open-label study.

Ingestion of the medical device by the volunteer
University Hospital Grenoble Alpes
Grenoble, France
Demonstrate the absence of adverse events (safety of the medical device) and that the device is analyzable (performance of the medical device).
Safety is assessed with the absence of grade \>3 adverse events. Performance is assessed by the presence of at least one capsule found in the stool with a satisfactory visual condition of capsule and with a sufficient volume of its contents within 96 hours after ingestion. The primary objective of this study is met if safety and performance are achieved for at least 12 of 15 volunteers.
Time frame: From 96 hours to 15 days
Number and grade of adverse events collected during the capsule collection period
In order to verify the safe use of the medical device the number and grade of adverve events are collected from 96 hours to 1 month.
Time frame: From 96 hours to 15 days
Number of capsules found to verify that the medical device passes through the human body
Recovery of 3 capsules per volunteer
Time frame: From 96 hours to 15 days
Verify that the medical device has captured intestinal fluid
Measurement of the volume contained in each capsule.
Time frame: From 96 hours to 15 days
Verify that the medical device has opened in the intestine
pH measurement of the contents of each capsule.
Time frame: From 96 hours to 15 days
Absence of tears and detachment of the various elements of the capsule
Visual inspection of the capsule after collection to determine absence of tears and detachment of the various elements
Time frame: From 96 hours to 15 days

Metagenomic analysis using 16s sequencing will provide data to establish differences in the gut microbiota profile/composition between capsule and faecal contents.
Metabolomic profile of capsule and faecal contents will be assessed by untargeted metabolomics. Identification, relative quantification and listing of metabolites specific to a sampling method will be generated.Microbiota will be described in terms of alpha and beta diversity, phylum, genus, OTU
Time frame: From 96 hours to 15 days
Medical device usability and acceptability : descriptive analysis
Registration of volunteer sensation during medical device ingestion using a questionnaire without scale. A descriptive analysis will be done with the answers.
Time frame: From 96 hours to 15 days
Obtain an overview of the sample's functional potential and identify biomarkers (organisms) via culturomics, on samples from up to 2 subjects.
Results of culturomic analysis of capsule contents, on up to 2 subjects.
Time frame: From 96 hours to 2 months
