ABSTRACT The timing of immunosuppressive therapy used in combination with post-transplantation cyclophosphamide (PTCY) in haploidentical hematopoietic stem cell transplant (haplo-HSCT) is not standardized. We evaluated the schedules of immunosuppression therapy after haplo-HSCT in 509 patients with acute leukemia receiving PTCY on days +3 and +4 along with tacrolimus (group 1; n = 215), with cyclosporine A (CSA) and mycophenolate mofetil (MMF) from day +5 (group 2; n = 170), or CSA + MMF from day 0 or 1 with PTCY on days +3 and +5 (group 3; n = 124). Compared with the other 2 groups, patients in group 3 were younger (median age, 46 years; P = .02) and more often received bone marrow (77%; P
