What this study is about

This trial is testing the safety, side effects, best dose, and effectiveness of 225Ac-DOTA-Anti-CD38 daratumumab monoclonal antibody in combination with fludarabine, melphalan and total marrow and lymphoid irradiation (TMLI) as conditioning treatment for donor stem cell transplant in patients with high-risk acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL) and myelodysplastic syndrome (MDS). Daratumumab is a type of medication called monoclonal antibody that binds to a protein called CD38, which is found on some types of immune cells and cancer cells. This treatment may block CD38 and help the immune system kill cancer cells.
