Minitransplants With HLA-matched Donors : Comparison Between 2 GVHD Prophylaxis Regimens

May 8, 2024 updated by: Yves Beguin, University of Liege

Allogeneic Hematopoietic Cell Transplantation From HLA-matched Donors After Reduced-intensity Conditioning: a Phase II Randomized Study Comparing 2 GVHD Prophylaxis Regimens

The present project is a multicenter phase II trail aiming at comparing which of the two postgrafting immunosuppressive regimens proposed in this study will be best suited to prevent graft-versus-host disease (GVDH).

The immunosuppressive regimens will consist of: Tacrolimus plus Mycophenolate Mofetil or Tacrolimus plus Sirolimus. Before grafting patients will undergo a reduced-intensity conditioning with Fludarabine/total body irradiation (TBI) or Fludarabine/Busulfan/anti-thymoglobuline. Following the interim analysis of October 2014, the protocol has been amended to allow inclusion only after Flu-TBI conditioning. The hypothesis is that the Tacrolimus plus Sirolimus regimen will be associated with better progression-free survival due to a lower incidence of relapse/progression.
