About this trial
Graft failure is a fatal complication following allogeneic stem cell transplantation where a second transplantation is usually required for salvage. There are no recommended regimens for second transplantations for graft failure, especially in the haploidentical transplant setting. We recently reported encouraging outcomes using a novel method (haploidentical transplantation from a different donor after conditioning with fludarabine and cyclophosphamide). However, the study was performed in single-center and with very small sample size. Therefore, it should be further validated via multicenter study. In this multi-center study, we aim to further evaluate the safety and efficacy of this protocol.
