Post Transplant Cyclophosphamide (PTCY) as Sole Graft Versus Host Disease (GVHD) Prophylaxis for Matched Allotransplant: CYRIC — CYRIC  

Graft Versus Host Disease Clinical Trial

Official title: Phase II Study Testing Prophylaxis Feasibility of Graft Versus Host Disease With Only High Dose Cyclophosphamide Post-transplantation for Patients Eligible to a Reduced-intensity Conditioning Regiment Prior to Allogenic Transplantation With a Compatible Familial or Non-familial Donor.

Status Terminated

Clinical Trial Summary

Acute or chronic graft versus host disease is still the major complication of stem cells transplantation regarding morbidity and mortality.

Recently, high dose cyclophosphamide utilization early after post-transplantation (day+ 3 and +4) not only for patients with HLA- haploidentical donor but also for patients with Human Leukocyte Antigen (HLA)-compatible donor, showed a great control of graft versus host disease after transplantation, allowing to consider stopping immunosuppressive treatment after the transplantation (Neoral=cyclosporine, cell-cept=mycophenolate mofetil). Indeed, this step has already been completed in myeloablative transplantation in adult patients.

This approach could enable to avoid in the end several complications related to long term immunosuppressive drugs administration, while promoting quicker immunity recovery.

Clinical Trial Description

The BALTIMORE conditioning regiment will be used in this study with peripheral stem cell transplantation and fludarabine will be replaced by clofarabine for myeloid diseases (Acute Myeloide Leukemia, Myelodysplasia , myelofibrosis, Chronic Myeoloid Leukemia..) because of better antitumoral activity in this setting. ;
