Allogeneic hematopoietic stem cell transplantation (HSCT) is performed as a curative treatment for children with nonmalignant diseases, such as bone marrow failure syndromes and primary immunodeficiencies. Because graft-versus-host-disease (GVHD) is a major factor affecting survival probability and quality of life after HSCT, the availability of HLA-matched donors restricts the application of HSCT. Recently, HSCT with post-transplantation cyclophosphamide (PTCy) has emerged as a potent method to prevent GVHD after HSCT from HLA-haploidentical donors, and some studies have suggested the safety of PTCy-HSCT for nonmalignant diseases. We conducted a prospective clinical trial aiming to help confirm the safety of HSCT and further reduction of GVHD using a combination of PTCy and low-dose antithymocyte globulin (ATG) from HLA-mismatched related donors for children with nonmalignant diseases. Six patients underwent HSCT and achieved engraftment at a median of 14.5 days, and no patient developed severe acute GVHD. All patients had sustained donor chimerism without developing chronic GVHD at the last follow-up. In conclusion, HSCT with PTCy and low-dose ATG from an HLA-mismatched related donor were feasible to control GVHD for nonmalignant diseases in the children involved in our study. © 2020 American Society for Transplantation and Cellular Therapy.
