A Multi-Center, Phase 3, Randomized Trial of Matched Unrelated Donor (MUD) versus HLA-Haploidentical Related (Haplo) Myeloablative Hematopoietic Cell Transplantation for Children, Adolescents, and Young Adults (AYA) with Acute Leukemia or Myelodysplastic Syndrome (MDS) ASCT2031
Objective
Primary Aims: To compare the 1-year cumulative incidence of severe GVHD (from day of HCT) defined as Grade III-IV acute GVHD (aGVHD) and/or chronic GVHD (cGVHD) that requires systemic immunosuppression and to compare the disease free survival (DFS) (from time of randomization) in children and young adults (AYA) with acute myeloid leukemia (AML), acute lymphoid leukemia (ALL), and Myelodysplastic Syndrome (MDS) who are randomly assigned to haploHCT or to an 8/8 adult MUD HCT.
Secondary Aims: To compare overall survival (OS) between children and AYA with AML/ALL/MDS randomly assigned to haploHCT and MUD HCT. To compare differences in health-related quality of life (HRQOL) between haploHCT and MUD HCT from baseline (pre-transplant), at 6 months, 1 year and 2 years post-transplant.
