Overview
Tab Title Description
Study type
InterventionalDescribes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study
RATIONALE: Giving chemotherapy before a donor stem cell transplant using stem cells that closely match the patient's stem cells, helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving antithymocyte globulin before transplant and cyclosporine, tacrolimus, and methotrexate before and after transplant may stop this from happening.
PURPOSE: Natural Killer (NK) cells from the donor's bone marrow may be important in fighting leukemia. Bone marrow donors can be selected based on the type of NK cells they have, specifically the killer immunoglobulin receptor (KIR) type. This study provides information on KIR type from potential donors, which can be used in selecting the bone marrow donor. This phase II trial of unrelated donor stem cell transplant in patients with high risk AML (monosomy 7, -5/5q-, high FLT3-ITD AR, or refractory or relapsed AML) in which KIR typing of the patients and potential donors will be available to the treating transplant physician at the time of donor selection.
Participation eligibility
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
Inclusion Criteria
