Fecal Microbiota Transplantation to Prevent Complications After Stem Cell Transplantation

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

Phase 2 Interventional University Hospital, Clermont-Ferrand · NCT04935684

This study is testing whether giving a special stool treatment can help prevent complications like Graft-versus-Host Disease in patients receiving stem cell transplants for blood cancers.

What this trial studies

This clinical trial evaluates the efficacy of Fecal Microbiota Transplantation (FMT) in preventing complications, particularly Graft-versus-Host Disease (GvHD), in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) for hematologic malignancies. It is a prospective, open-label, multi-center, parallel, randomized phase II trial comparing outcomes between patients receiving FMT and those who do not. The primary objective is to assess the impact of FMT on GvHD and relapse-free survival at one year, while secondary objectives include overall survival, progression-free survival, and safety of the procedure.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 or older undergoing myelo-ablative allo-HSCT for controlled hematologic malignancies.

Not a fit: Patients with tumor progression at the time of allo-HSCT or those with serious uncontrolled diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of Graft-versus-Host Disease and improve overall survival rates in patients undergoing stem cell transplantation.

How similar studies have performed: While the approach of using FMT in this context is novel, preliminary studies have suggested potential benefits in related areas, indicating a promising avenue for further exploration.
