Low risk of chronic graft-versus-host disease and relapse associated with T cell-depleted peripheral blood stem cell transplantation for acute myelogenous leukemia in first remission: results of the blood and marrow transplant clinical trials network protocol 0303.

ABSTRACT: Graft-versus-host disease (GVHD) is most effectively prevented by ex vivo T cell depletion (TCD) of the allograft, but its role in the treatment of patients undergoing allogeneic hematopoietic cell transplantation (HCT) for acute myelogenous leukemia (AML) in complete remission (CR) remains unclear. We performed a phase 2 single-arm multicenter study to evaluate the role of TCD in AML patients in CR1 or CR2 up to age 65 years. The primary objective was to achieve a disease-free survival (DFS) rate of >75% at 6 months posttransplantation. A total of 44 patients with AML in CR1 (n = 37) or CR2 (n = 7) with a median age of 48.5 years (range, 21-59 years) received myeloablative chemotherapy and fractionated total body irradiation (1375 cGy) followed by immunomagnetically selected CD34-enriched
