A Comparison Study of Reduced Dose of Post-transplantation Cyclophosphamide (PTCy 40mg/kg) Versus Standard (PTCY 50mg/kg): a Multi-center Study for Halo-identical Donor Transplantation
A Comparison Study of Reduced Dose of Post-transplantation Cyclophosphamide (PTCy 40mg/kg) Versus Standard (PTCY 50mg/kg): a Multi-center Study for Halo-identical Donor Transplantation
Post-transplantation cyclophosphamide (PTCY) is considered as major graft versus host disease (GVHD) prophylaxis. In our previous study, the investigators demonstrated that the standard dose PTCY of 50mg/kg with tacrolimus and post-engrafted low-dose anti-thymoglobulin (ATG) achieved low incidence of acute GVHD. More recently, it has been shown that reduced dose of PTCY of 40mg/kg is considered with similar efficacy as GVHD prophylaxis, In this study, a multi-center randomized comparison is planned to evaluate the clinical outcome of GVHD prophylaxis of PTCy 40 versus 50.

In our previous study, the investigators demonstrated that the standard dose PTCY of 50mg/kg with tacrolimus and post-engrafted low-dose anti-thymoglobulin (ATG) achieved low incidence of acute GVHD. In the clinical setting, reduced dose of PTCY (40mg/kg) was used for patients over 60 or with high HCT-CI and the overall incidence of acute GVHD was similar to PTCY 50mg/kg but chronic GVHD was slightly increased. To confirmed our observation, in this study, a prospective multiple-center randomized comparison is planned to evaluate the clinical outcomes of reduced dose of PTCY (40mg/kg) versus 50mg/kg as GVHD prophylaxis.
