Clinical trial

Faecal Microbiota Transplantation for Prevention of Graft-versus-host Sisease After Allogeneic Stem Cell Transplantation for Haematological Malignancies

Name

PHRC N 2018 BAY

Description

The aim of this study is to assess the Fecal Microbiota Transplantation (FMT) efficacy in the prevention of allogeneic hematopoietic stem cell transplantation (allo-HSCT) complications and particularly Graft versus Host Disease (GvHD). The hypothesis of this study is that allogeneic FMT may improve outcomes of these patients.

Treatment

Fecal Microbiota Transplantation

Patients randomized in the "FMT group" will received FMT within 4 weeks following neutrophils recovery after the allo-HSCT procedure. The stool transplant will be done by enema. The day before FMT, patient will undergo bowel cleansing by ingestion of two liters of polyethylene glycol solution. The day of FMT, a colon cleanse enema will be performed in the morning and FMT will be delivered around two hours after the cleanse enema. This colic preparation is essential to optimize the results of FMT. The enema (50g of stools diluted in 250mL of NaCl 0.9%) will be performed by a qualified member of the study team (nurse) by using a rectal cannula (within 6 hours of thawing). The enema will have to be kept by the patient for as long as possible and at least 30 minutes.
