This phase I studies the side effects and best dose of total marrow and lymphoid irradiation when given together with fludarabine and melphalan before donor stem cell transplant in treating participants with high-risk acute leukemia or myelodysplastic syndrome. Giving chemotherapy, such as fludarabine and melphalan, and total marrow and lymphoid irradiation before a donor stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets.

PHASE1
PRIMARY OBJECTIVES: I. To determine the maximum tolerated dose/recommended phase II dose (MTD/RP2D) of total marrow and lymphoid irradiation (TMLI) with fixed doses of fludarabine and melphalan (FM100) as a preparative regimen in patients undergoing allogeneic hematopoietic stem cell transplantation (alloHCT) and who are not eligible for standard myeloablative regimens, with either a matched donor (Arm A) or a haploidentical donor (Arm B). II. To describe toxicities attributable to TMLI by dose level in patients treated under this regimen. SECONDARY OBJECTIVES: I. To evaluate the safety of the regimen, at each dose level, by assessing the following: type, frequency, severity, attribution, time course and duration of adverse events, including acute/chronic graft versus host disease (GVHD), infection and delayed engraftment. II. To investigate the temporal effect of bone marrow residual damage in alloHCT patients after TMLI/FM100. III. To estimate overall survival (OS), event-free survival (EFS), cumulative incidence (CI) of relapse/progression, and non-relapse mortality (NRM) at 100 days, 1 year and 2 years. IV. Assess minimal residual disease (MRD) from bone marrow aspirates on days 30, 100, and 180 post-transplant and describe its relation to TMLI dose level and patient disease status. V. To evaluate effect of TMLI/FM100 conditioning on immune reconstitution after alloHCT in patients receiving stem cells from matched or haploidentical donors. OUTLINE: This is a dose-escalation study of TMLI. Participants undergo TMLI twice daily (BID) on days -8 to -5, and receive fludarabine intravenously (IV) on days -4 to -2 and melphalan on day -2. Participants then undergo alloHCT on day 0. After completion of study treatment, participants are followed up twice weekly for 100 days, twice monthly for 6 months, and then monthly or yearly for up to 2 years.
