Brief Summary
This phase I trial tests the safety, side effects and effectiveness of emapalumab with post-transplant cyclophosphamide, tacrolimus, and mycophenolate mofetil in preventing graft-versus-host disease (GVHD) in patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) after reduced-intensity donor (allogeneic) hematopoietic cell transplant (HCT). Giving chemotherapy, such as fludarabine, melphalan, or busulfan, before a donor \[peripheral blood stem cell\] transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. When healthy stem cells for a donor are infused into a patient (allogeneic HCT), they may help the patient's bone marrow make more healthy cells and platelets. Allogeneic HCT is an established treatment, however, GVHD continues to be a major problem of allogeneic HCT that can complicate therapy. GVHD is a disease caused when cells from a donated stem cell graft attack the normal tissue of the transplant patient. Emapalumab binds to an immune system protein called interferon gamma. This may help lower the body's immune response and reduce inflammation. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid and may kill cancer cells. It may also lower the body's immune response. Tacrolimus is a drug used to help reduce the risk of rejection by the body of organ and bone marrow transplants. Mycophenolate mofetil is a drug used to prevent GVHD after organ transplants. It is also being studied in the prevention of GVHD after stem cell transplants for cancer, and in the treatment of some autoimmune disorders. Mycophenolate mofetil is a type of immunosuppressive agent. Giving emapalumab with post-transplant cyclophosphamide, tacrolimus and mycophenolate mofetil may be safe, tolerable and/or effective in preventing GVHD in patients with AML or MDS after a reduced-intensity allogeneic HCT.

Viral load must be undetectable * Meets other institutional and federal requirements for infectious disease titer requirements * Note Infectious disease testing to be performed within 28 days prior to day 1 of protocol therapy * QuantiFERON-TB Gold+ * Administer tuberculosis prophylaxis to patients at risk for tuberculosis, or known to have a positive purified protein derivative (PPD) test result, or positive interferon gamma (IFNγ) release assay * Women of childbearing potential (WOCBP): negative urine or serum pregnancy test * If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required * Agreement by females and males of childbearing potential to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 180 days post-HCT * Childbearing potential defined as not being surgically sterilized (men and women) or have not been free from menses for \> 1 year (women only) Exclusion Criteria: * Prior allogeneic HCT * Other cancer therapies (chemotherapy, radiation, biologics) are not allowed within two weeks of starting HCT conditioning; however targeted agents for underlying hematologic malignancies may be continued up to one day before conditioning, including, but not limited to: * FLT3 inhibitors * IDH1/2 inhibitors * Menin inhibitors * ABL-BCR inhibitors * BCL-2 inhibitors * Hydroxyurea * History of allergic reactions attributed to compounds of similar chemical or biologic composition to study agent * Psychological issues, no appropriate caregivers identified, or non-compliant to medication * Clinically significant uncontrolled illness * Active uncontrolled infections (bacterial, viral, fungal).
