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.
The TMF-Allo study is a prospective, open-label, multi-center, parallel, randomized phase II clinical trial comparing a group patients with FMT and a control group of patients without FMT.
The main objective of this study is to assess the effect of allogeneic FMT versus no treatment on Graft-versus-host disease and Relapse-Free Survival (GRFS) at one year in adult patients treating with myelo-ablative allo-HSCT for haematologic malignancy.
The secondary objectives are to evaluate :

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Group 1: Fecal Microbiota Transplantation (FMT) | Experimental | Patients randomized in the "FMT group" will received FMT. FMT product will be made by the the pharmacy of the Clermont-Ferrand University Hospital from stools of healthy volunteer donors within 6 hours after defecation in order to preserve the viability of the bacteria. The preparation will be standardized: 50g aliquots will be prepared and diluted in 250mL of 0.9% NaCl containing 10% glycerol, until a homogeneous suspension is obtained. The preparation will be rapidly frozen at -80°C until use, with a maximum shelf life of 18 months. |
|
| Group 2: no intervention | No Intervention | The comparator group will be constituted by patients randomized in the "no FMT" group. For ethical reasons, these patients will not receive any FMT and therefore no enema or colic preparation. No placebo will be administered. Prophylactic anti-infective treatments can be introduced at any time. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Fecal Microbiota Transplantation | Drug | 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. |

Progression-free survival is defined as the time period between the date of randomization and the date of disease relapse or progression or death, regardless of its cause. |
| At Day 360 and Day 720 after allogeneic hematopoietic stem cell transplantation |
| Haematopoietic reconstitution | Haematopoietic reconstitution is assessed by: 1/ turnaround time of polynuclear neutrophils >0.5.10^9/L (first day within a period of three consecutive days); 2/ spontaneous platelet turnaround time >20.10^9/L (two days with no platelet transfusion within the previous three days); 3/ spontaneous platelet turnaround time >50.10^9/L (two days with no platelet transfusion within the previous three days); 4/ the number of transfusions of red blood cells and platelets between D0 and D100 | At the time of haematopoietic reconstitution |
| Engraftment rates | Engraftment rates are evaluated by a chimerism measure (by molecular biology) | At Day 30, Day 60, Day 90, Day 180, Day 360 and Day 720 after allogeneic hematopoietic stem cell transplantationday |
| Cumulative incidence of acute GvHD | Acute GvHD severity is defined according to MAGIC criteria. It will be notified by specifying the location (liver, skin, gut …), the severity score (II to IV), the treatment applied and the efficacy of treatment. GvHD occurrence will be notified every week until D30 (minimum) or until hospital discharge, then monthly until D180 and at D270, D360, D540 and D720. | At Day 360 after allogeneic hematopoietic stem cell transplantation |
| Cumulative incidence of chronic GvHD | Chronic GvHD severity will be defined according to NIHCC criteria. It will be notified by specifying the location (liver, skin, gut …), the severity score (II to IV), the treatment applied and the efficacy of treatment. GvHD occurrence will be notified every week until ungraftment, then monthly until D180 and at D270, D360, D540 and D720. | At Day 720 after allogeneic hematopoietic stem cell transplantation |
| Transplant-Related Mortality | Transplant-related mortality is defined as death due to causes unrelated to the underlying disease. | At Day 180, Day 360 and Day 720 after allogeneic hematopoietic stem cell transplantation |
| Cumulative incidence of infections | Infectious complications will be notified every week up to day 30 (minimum) or until hospital discharge, then every month up to D180 and from D270 to D360, according to the existence of a documented bacteraemia, germ resistance, type and number of days of curative antibiotherapy used; the existence of a documented fungal infection and the type and number of days of curative antifungal treatment; the existence of a documented viral infection and the type and number of days of curative antiviral treatment; the need of an intensive care unit transfer due to an infectious complication. | At Day 360 after allogeneic hematopoietic stem cell transplantation |
| Severe infections description | Severe infections will be defined according to GREFIG score : bactearemia with severe sepsis, complex bactearemia (with deep organ involvement), candidemia (at least one positive blood culture) with sepsis or deep infected site, proven or probable aspergillosis pneumonia, severe varicella-zoster virus infection (involvement of a deep organ or associated coagulopathy), any viral encephalitis, CMV infection with lung or digestive location, Pneumocystis jiroveci pneumonia, toxoplasmosis with involvement of organ or central nervous system, any acute pneumonia with PaO2 less than or equal to 65mmHg, any sepsis requiring transfer to an intensive care unit. | From the day of inclusion to Day 360 after allogeneic hematopoietic stem cell transplantation |
| Impact of Fecal Microbiota Transplantation (FMT) on multi-resistant bacteria, extended-spectrum beta-lactamases and Clostridium difficile infection | Impact of FMT on multi-resistant bacteria, extended-spectrum beta-lactamases and Clostridium difficile infection will be assessed by evaluation of persistence or disappearance of these pathogenic bacteria after FMT. | At Day 360 after allogeneic hematopoietic stem cell transplantation |
| Unexpected event description that could be in relation with FMT of Fecal Microbiota Transplantation (FMT) | Each unexpected event that could be in relation with FMT will be notified: abdominal pain, diarrhea, bacterial translocation or any adverse effect attributed to the enema. | From the day of FMT to Day 360 after allogeneic hematopoietic stem cell transplantation |
| Quality of life assessment | The quality of life will be auto-evaluated by the patients using a validated questionnaire: European Organisation for Research and Treatment of Cancer- Quality of Life Questionnaire-Core 30 (EORTC-QLQ-C30). The QLQ-C30 is composed of both multi-item scales and single-item measures. These include five functional scales, three symptom scales, a global health status / QoL scale, and six single items. Each of the multi-item scales includes a different set of items - no item occurs in more than one scale. All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level. Thus a high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / QoL represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems. | at Day -7, Day 30, Day 90, Day 180, Day 360 and Day 720 after allogeneic hematopoietic stem cell transplantation |
