Testing the Anti-cancer Drug, Cirtuvivint, and Its Combination With ASTX727 to Improve Outcomes in Patients With Acute Myeloid Leukemia and Myelodysplastic Syndromes
This phase I trial tests the safety, side effects, and best dose of SM08502 (cirtuvivint) alone and in combination with ASTX727 in treating patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). Cirtuvivint may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. ASTX727 is a combination of two drugs, decitabine and cedazuridine. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have a greater effect. Giving cirtuvivint alone or in combination with ASTX727 may be safe, tolerable, and/or effective in treating patients with AML and MDS.

Pembrolizumab and Decitabine With or Without Venetoclax in Treating Patients With Acute Myeloid Leukemia or Myelodysplastic Syndrome That Is Newly-Diagnosed, Recurrent, or Refractory
This phase Ib trial studies the side effects and best dose of pembrolizumab and how well it works in combination with decitabine with or without venetoclax in treating patients with acute myeloid leukemia or myelodysplastic syndrome that is newly-diagnosed, has come back (recurrent), or does not respond to treatment (refractory). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. This trial may help doctors find the best dose of pembrolizumab that can be safely given in combination with decitabine with or without venetoclax, and to determine what side effects are seen with this treatment.

CLAG-M or FLAG-Ida Chemotherapy and Reduced-Intensity Conditioning Donor Stem Cell Transplant for the Treatment of Relapsed or Refractory Acute Myeloid Leukemia, Myelodysplastic Syndrome, or Chronic Myelomonocytic Leukemia
This phase I trial studies the best dose of total body irradiation when given with cladribine, cytarabine, filgrastim, and mitoxantrone (CLAG-M) or idarubicin, fludarabine, cytarabine and filgrastim (FLAG-Ida) chemotherapy reduced-intensity conditioning regimen before stem cell transplant in treating patients with acute myeloid leukemia, myelodysplastic syndrome, or chronic myelomonocytic leukemia that has come back (relapsed) or does not respond to treatment (refractory). Giving chemotherapy and total body irradiation 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 the healthy stem cells from a donor are infused into a patient, they may help the patient's bone marrow make more healthy cells and platelets and may help destroy any remaining cancer cells. Sometimes the transplanted cells from a donor can attack the body's normal cells called graft versus host disease. Giving cyclophosphamide, cyclosporine, and mycophenolate mofetil after the transplant may stop this from happening.

Navitoclax in Relapsed or Refractory High-Risk Myelodysplastic Syndrome
This trial tests the safety, side effects, and best dose of navitoclax in combination with venetoclax and decitabine in treating patients with higher risk myelodysplastic syndrome (MDS) that has come back after initial treatment or was not responsive to initial treatment. This study will also look at the effectiveness of the treatment combination and patient's quality of life while on these medications. Navitoclax is an oral drug that works as an inhibitor of the BCL-2 family of proteins, which are often overly expressed in a wide variety of cancers and are linked to tumor drug resistance. This drug blocks some of the enzymes that keep cancer cells from dying. Venetoclax is an oral drug that works as an inhibitor of BCL-2 proteins that works very similarly to navitoclax by blocking the action of a certain proteins in the body that helps cancer cells survive which helps to kill cancer cells. Decitabine is an intravenous drug. It is a hypomethylating agent which means it interferes with deoxyribonucleic acid (DNA) methylation. DNA methylation is a major factor that regulates gene expression in cells, and an increase in DNA methylation can block the genes that regulate cell division and growth. When these genes are blocked the overall result allows or promotes cancer as there is no control over cell growth. Decitabine stops cells from making DNA and may kill cancer cells. Participation in this trial may improve the understanding of both chemotherapy response in MDS and mechanisms of resistance to current therapies.

HA-1 T TCR T Cell Immunotherapy for the Treatment of Patients With Relapsed or Refractory Acute Leukemia After Donor Stem Cell Transplant
This phase I trial studies the side effects and best dose of CD4+ and CD8+ HA-1 T cell receptor (TCR) (HA-1 T TCR) T cells in treating patients with acute leukemia that persists, has come back (recurrent) or does not respond to treatment (refractory) following donor stem cell transplant. T cell receptor is a special protein on T cells that helps them recognize proteins on other cells including leukemia. HA-1 is a protein that is present on the surface of some peoples' blood cells, including leukemia. HA-1 T cell immunotherapy enables genes to be added to the donor cells to make them recognize HA-1 markers on leukemia cells.

Highest Dose of Uproleselan in Combination With Fludarabine and Cytarabine for Patients With Acute Myeloid Leukemia, Myelodysplastic Syndrome, or Mixed Phenotype Acute Leukemia Relapsed or Refractory That Expresses E-selectin Ligand on the Cell Membrane
This phase I trial tests the safety, side effects, and determination of the best dose of uproleselan in combination with fludarabine and cytarabine in treating patients with acute myeloid leukemia, myelodysplastic syndrome or mixed phenotype acute leukemia that has come back (relapsed) or does not respond to treatment (refractory) and that expresses E-selectin ligand on the cell membrane. Uproleselan binds to E-selectin expressed on endothelial cells of the bone marrow and prevents their interaction with selectin-E ligand-expressing cancer cells. This may prevent leukemia cells from being sequestered in the bone marrow niche and escaping the effect of chemotherapy. Chemotherapy drugs, such as fludarabine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving uproleselan in combination with fludarabine and cytarabine may expose more cancer cells to the effect of chemotherapy.

Chemotherapy (Decitabine in Combination With FLAG-Ida) and Total-Body Irradiation Followed by Donor Stem Cell Transplant for the Treatment of Adults With Myeloid Malignancies at High Risk of Relapse
This phase I/II trial studies the safety, side effects, and best dose of decitabine in combination with fludarabine, cytarabine, filgrastim, and idarubicin (FLAG-Ida) and total body irradiation (TBI) followed by a donor stem cell transplant in treating adult patients with cancers of blood-forming cells of the bone marrow (myeloid malignancies) that are at high risk of coming back after treatment (relapse). Cancers eligible for this trial are acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and chronic myelomonocytic leukemia (CMML). Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. The FLAG-Ida regimen consists of the following drugs: fludarabine, cytarabine, filgrastim, and idarubicin. These are chemotherapy drugs that work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Filgrastim is in a class of medications called colony-stimulating factors. It works by helping the body make more neutrophils, a type of white blood cell. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. TBI is radiation therapy to the entire body. Giving chemotherapy and TBI before a donor peripheral blood stem cell (PBSC) 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 the healthy stem cells from a donor are infused into a patient, they may help the patient's bone marrow make more healthy cells and platelets. Giving decitabine in combination with FLAG-Ida and TBI before donor PBSC transplant may work better than FLAG-Ida and TBI alone in treating adult patients with myeloid malignancies at high risk of relapse.
