This study will assess the safety, efficacy, and feasibility of ⍺/β CD3+ T-cell and CD19+ B-cell depletion in allogeneic stem cell transplantation in patients with acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML), juvenile myelomonocytic leukemia (JMML), high risk myelodysplastic syndrome (MDS), chronic myeloid leukemia (CML) and lymphoma. Subjects will receive an allogeneic stem cell transplant that has been depleted of ⍺/β CD3+ T-cells and CD19+ B-cells using the Miltenyi CliniMACS Prodigy® system.
ALL high risk including one or more of the following: (t(9;22) or 11q23 chromosomal abnormality, primary induction failure (≤15% blasts at time of registration), mixed phenotype acute leukemia (MPAL), persistent MRD (≥0.01% by flow or persistent abnormal karyotype detected by cytogenetics) or hypodiploidy (≤44 chromosomes)) in first remission
ALL in second remission and beyond
History of AML induction/reinduction Failure (≤15% blasts at time of registration)
AML in CR1 with poor cytogenetics (i.e., 12p, 5a, -7, FLT3 mutation/duplication, t(9;11) and others)
None
