Design outcomes

Primary

MeasureTime frame
Main Objective: To compare anti-leukemic activity of allogeneic stem cell trans-plantation for patients with acute leukemia, in complete remis-sion between a 10/10 HLA matched unrelated donor and a haploidentical donor.;Secondary Objective: To assess and compare the safety and efficacy of study treat-ments therapy in both study arms on non-relapse mortality (NRM), relapse-free survival (RFS), Overall survival (OS), QOL, toxicity, development of acute and chronic GvDH as well as engraftment and chimerism and impact of measurable residual disease.;Primary end point(s): 1. Relapse incidence at two years between both arms;Timepoint(s) of evaluation of this end point: Baseline, Day 30, Day 100, 6 months, 12 months, 24 months

Secondary

MeasureTime frame
Secondary end point(s): 1. Overall survival at two years between both arms 2. Overall survival for all patients assigned to one of the two treatment arms as time to event endpoint 3. Comparison of GVHD/relapse-free survival as composite endpoint in both arms 4. Comparison of non-relapsed mortality (NRM) at 1 and 2 years after allogeneic SCT in both arms 5. Comparison of acute graft-versus-host disease (aGVHD) on day +100 and 1 year (max grade) after allogeneic SCT according to the Glucksberg scale revised by Przepiorka et al. between both arms 6. Comparison of chronic graft-versus-host disease (cGVHD) according to the NIH consensus criteria of Jagasia et al. at 1 and 2 years after allogeneic SCT between both arms 7. Comparison of toxicity of both regimens scored according to the current version of the NCI CTCAE between both arms 8. Comparison of immune reconstitution and full donor chimerism between both arms 9. Evaluation of Sorror Risk Score [8] (Appendix 13.1) on outcome after allogeneic SCT 10. Comparison of QOL (FACT-BMT) before and after transplantation at + 100 days, 6 months, 1 year, 2 years between both arms;Timepoint(s) of evaluation of this end point: Baseline, Day 30, Day 100, 6 months, 12 months, 24 months
