PTCy-ATG vs ATG in Haploidentical HSCT for Acute Graft-versus-host Disease Prophylaxis

Phase 4
Conditions
Hematopoietic Stem Cell Transplantation
Interventions
Registration Number
NCT03689465
Lead Sponsor
Nanfang Hospital, Southern Medical University
Brief Summary

The granulocyte colony-stimulating factor (G-CSF)+antithymocyte globulin (ATG)-based protocols and posttransplantation cyclophosphamide (PTCy) protocols have been widely used for graft-versus-host disease (GVHD) prophylaxis in haploidentical related donor transplantation (haplo-HSCT). Nevertheless, severe acute GVHD remains an obstacle for haplo-HSCT. This study is aim to evaluate the efficacy of a modified protocol that includes PTCY and ATG in recipients of haplo-HSCT.

Detailed Description

Haploidentical related donor transplantation is now considered an important alternative to allogeneic hematopoietic stem cell transplantation (allo-HSCT). Currently, the strategies for graft-versus-host disease (GVHD) prophylaxis mainly include ex vivo and in vivo T-cell depletion (TCD) in haploidentical HSCT (haplo-HSCT). In vivo TCD modalities have become mainstream including granulocyte colony-stimulating factor (G-CSF)+antithymocyte globulin (ATG)-based protocols and posttransplantation cyclophosphamide (PTCy) protocols. The ATG strategy has been widely used. Nevertheless, severe acute GVHD remains an obstacle for haplo-HSCT. In addition, infections, especially viral infections, remain an important drawback of this strategy. This study is aim to evaluate the efficacy of a modified protocol that includes PTCY and ATG in recipients of haplo-HSCT.
