The purpose of this study is to reduce the regimen related toxicities and transplantation related mortality after allogeneic stem cell transplantation in adult acquired aplastic anemia (AA), the trials of reduced dose of Cy along with fludarabine and ATG were performed.11-21 The investigators preliminary data of randomized comparison of cyclophosphamide plus fludarabine versus cyclophosphamide alone in addition to anti-thymocyte globulin for the conditioning therapy in allogeneic hematopoietic cell transplantation for bone marrow failure syndrome supports reduced dose of Cy along with fludarabine and ATG.
Conditioning regimen without Cy may reduce RRT because Cy-containing conditioning remains several RRT such as hemorrhagic cystitis, SOS and graft versus host disease (GvHD). Recently there were small trials of fludarabine and ATG (Flu-ATG) for the conditioning regimen of alloHSCT.22-24 These data raised the feasibility of fludarabine and ATG without Cy for patients with AA.
This new conditioning regimen of Flu-ATG will be compared to standard regimen of Cy- ATG in a randomized controlled trial.

- regimen-related toxicities(RRT) [ Time Frame: 7 years ]
- The RRTs will be evaluated in terms of mucositis, hemorrhagic cystitis, SOS, acute graft versus host disease (GvHD), infection rate, graft failure, time to engraftment.
- Overall feasibility will be evaluated by RRTs, time to engraftment, chronic GvHD, treatment-related mortality (TRM), relapse rate, infertility, chimerism status, changes of hemostatic variables, event-free survival and overall survival.
- Overall feasibility [ Time Frame: 7 years ]Day 100 mortality rate, overall survival
