简要总结
Currently, ANSM recommendations govern FMT (Fecal Microbiota Transplantation) in clinical trials. The collection and validation of these stool donations as part of the trials is complex and not very efficient. It therefore seems essential to identify the limiting factors and the characteristics of Healthy Volunteer Donors to optimize the number of valid stool donations.
详细描述
If the ANSM recommendations govern FMT (Fecal Microbiota Transplantation) in clinical trials, the selection, inclusion of Healthy Volunteer Donors (HVD), then the collection and validation of these stool donations is complex and not very effective. It therefore seems essential to identify the limiting factors and the characteristics of HVD to optimize the number of valid stool donations.
Healthy voluntary donors of stools for the preparation of TMF (Healthy Volunteer Donors, -TMF) for trials to evaluate its effectiveness in various pathologies will be selected, included and followed in a common protocol (ANSM agreement obtained) in order to facilitate this entire process and pool resources. This will allow us to describe the clinical characteristics and lifestyle habits of Healthy Volunteer Donors associated with the validity of stool donations.
