T-Replete Haploidentical Cell Transplantation Using Post-Transplant Cyclophosphamide for Acute Myeloid Leukemia, Acute Lymphoblastic Leukemia and Myelodysplastic Syndrome: Effect of Transplant Conditioning Regimen Intensity on Outcomes

The significance of conditioning regimen intensity on the outcomes of T-cell replete HLA-haploidentical transplants is not known. This study compared outcomes of commonly used myeloablative (MAC) to reduced intensity (RIC) conditioning regimens in 1325 such transplants (AML; n=818; ALL; n=286 and MDS; n=221) in the US between 2008 and 2016. The median age of the study population was 54 years (18 - 70). Most patients (80%) with AML and ALL were...
