NCT ID: NCT05477069

Last Updated: 2025-08-13

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 16 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2022-10-24
• Study Completion Date: 2023-11-06

Brief Summary

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.

Detailed Description

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.

Conditions

Healthy Volunteers

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
