phase 1-2 mahct w/ tcell depleted graft w/ simultaneous infusion conventional and regulatory t cell

Conditions: Myeloid Leukemia, Chronic; Acute Myelogenous Leukemia; Myelodysplastic Syndromes (MDS); Lymphoma, Non-Hodgkin; Acute Lymphoblastic Leukemia (ALL); Myeloproliferative Syndrome; Acute Myeloid Leukemia; Acute Leukemia; Chronic Myelogenous Leukemia

Summary: this study looks at giving specific types of immune cells, called regulatory t cells and conventional t cells, to patients with blood cancers who are receiving a stem cell transplant. these cells are added back to help the immune system recover and reduce complications after the transplant.

primary objectives: * to determine the efficacy, safety and feasibility of administration of several dose combinations of conventional t cells (tcon) and regulatory t cells (treg) in patients undergoing allogeneic hematopoietic cell transplantation (hct) with hla matched donors (related or unrelated) using a t cell depleted graft \[cd34+ hematopoietic progenitor cells ("cd34+ hspc")\], without immune suppression. * to determine the maximum tolerated dose of infused regulatory and conventional t cells in the matched donor setting * to determine 1 year event free survival (efs) post hct secondary objectives: * to determine the 1 year os in patients undergoing allogeneic hct with matched donors. * to measure the incidence and severity of acute and chronic graft vs host disease (gvhd) * to measure incidence of serious infections
