Itacitinib, Tacrolimus, and Sirolimus for the Prevention of GVHD in Patients With Acute Leukemia, Myelodysplastic Syndrome, or Myelofibrosis Undergoing Reduced Intensity Conditioning Donor Stem Cell Transplantation

This phase IIa trial studies the side effects of itacitinib when given together with standard treatment (tacrolimus and sirolimus), and to see how well it works in preventing graft-versus-host-disease (GVHD) in patients with acute leukemia, myelodysplastic syndrome or myelofibrosis who are undergoing reduced intensity conditioning donor stem cell transplantation. GVHD is a common complication after donor stem cell transplantation, resulting from donor immune cells recognizing recipients' cells and attacking them. Adding itacitinib to tacrolimus and sirolimus may reduce the risk GVHD and ultimately improve overall outcome and survival after donor stem cell transplantation.

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.

Quizartinib, Decitabine, and Venetoclax in Treating Participants With Untreated or Relapsed Acute Myeloid Leukemia or High Risk Myelodysplastic Syndrome

This phase I/II trial studies how well quizartinib, decitabine, and venetoclax work in treating participants with acute myeloid leukemia or high risk myelodysplastic syndrome that is untreated or has come back (relapsed). Quizartinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as decitabine and venetoclax, 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 quizartinib and decitabine may work better at treating acute myeloid leukemia and myelodysplastic syndrome.

MYELOMATCH: A Screening Study to Assign People With Myeloid Cancer to a Treatment Study or Standard of Care Treatment Within myeloMATCH (MyeloMATCH Screening Trial)

This MyeloMATCH Master Screening and Reassessment Protocol (MSRP) evaluates the use of a screening tool and specific laboratory tests to help improve participants' ability to register to clinical trials throughout the course of their myeloid cancer (acute myeloid leukemia or myelodysplastic syndrome) treatment. This study involves testing patients' bone marrow and blood for certain biomarkers. A biomarker (sometimes called a marker) is any molecule in the body that can be measured. Doctors look at markers to learn what is happening in the body. Knowing about certain markers can give doctors more information about what is driving the cancer and how to treat it. Testing patients' bone marrow and blood will show doctors if patients have markers that specific drugs can target. The marker testing in this study will let doctors know if they can match patients with a treatment study (myeloMATCH clinical trial) that tests treatment for the type of cancer they have or continue standard of care treatment with their doctor on the Tier Advancement Pathway (TAP).

225Ac-DOTA-Anti-CD38 Daratumumab Monoclonal Antibody With Fludarabine, Melphalan and Total Marrow and Lymphoid Irradiation as Conditioning Treatment for Donor Stem Cell Transplant in Patients With High-Risk Acute Myeloid Leukemia, Acute Lymphoblastic Leukemia and Myelodysplastic Syndrome

This phase I trial tests 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 in a class of medications called monoclonal antibodies. It binds to a protein called CD38, which is found on some types of immune cells and cancer cells. Daratumumab may block CD38 and help the immune system kill cancer cells. Radioimmunotherapy is treatment with a radioactive substance that is linked to a monoclonal antibody, such as daratumumab, that will find and attach to cancer cells. Radiation given off by the radioisotope my help kill the cancer cells. Chemotherapy drugs, such as fludarabine and melphalan, 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. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. TMLI is a targeted form of body radiation that targets marrow, lymph node chains, and the spleen. It is designed to reduce radiation-associated side effects and maximize therapy effect. Actinium Ac 225-DOTA-daratumumab combined with fludarabine, melphalan and TMLI may be safe, tolerable, and/or effective as conditioning treatment for donor stem cell transplant in patients with high-risk AML, ALL, and MDS.

Prophylactic DLI-X for Leukemia Relapse After HCT

The primary objective of this proposal is to conduct the first-in-human randomized clinical trial evaluating prophylactic DLI-X (pro-DLI-X) for relapse prevention following matched sibling donor (MSD) or haploidentical (haplo) hematopoietic cell transplantation (HCT) in patients with hematologic malignancies. We hypothesize that pro-DLI-X will demonstrate safety and superior efficacy by enhancing graft-versus-leukemia (GvL) effects mediated by natural killer (NK) cells, γδ T cells, and CD8+ T cells, while maintaining manageable and treatment-responsive graft-versus-host disease (GvHD).

Trial of 2 Step ATG for Prevention of Acute GVHD Post Allogeneic Stem Cell Transplant

In an effort to reduce graft versus host disease (GVHD) and enhance graft versus leukemia (GVL) effect post allogenic hematopoietic stem cell transplantation (AHSCT), recent research has focused on host immune cell depletion. Frame shifting anti-thymocyte globulin (ATG) backwards to earlier days before days 0 can result in deeper host and less graft T-cell depletion, leading to better immune reconstitution. Preliminary data where 80% of the ATG dose is given on days -6,-5,-4 and 20% given on day -1, showed effective prevention of severe acute GVHD, chronic GVHD and favorable early immune reconstitution. We hypothesize that our 2 step ATG dosing platform when combined with standard tacrolimus and mini methotrexate can prevent grade III-IV acute GVHD and chronic GVHD, resulting in improvement of GVHD/relapse free survival at one year post transplant.

Collection of Tissue Samples for Cancer Research

Background: -Patients who are being evaluated and/or treated at the NIH Clinical Center and adult patients at participating sites will be entered onto this tissue procurement protocol for collection of tissue specimens. Objectives: * To obtain samples from adult and pediatric patients for research purposes from tests and procedures that are done as required by the primary research protocol(s) to which a patient is enrolled or as part of their standard-of-care treatment. * To obtain samples for research purposes from non-surgical procedures, such as percutaneous biopsies, performed for the sole purpose of obtaining tissue specimens or biological fluids for this protocol. Eligibility: -Adult patients (18 years of age and older) and pediatric patients (younger than 18 years of age) who are being evaluated for and/or treated for cancer at the NIH Clinical Center participating sites. Design: * This is a multicenter tissue procurement protocol with NCI as the coordinating center. * For adult patients: specimens for research purposes, as outlined in this protocol, will be obtained from tests and procedures that are done as required by the primary research protocols to which a patient is enrolled or as part of their standard-of-care treatment. Non-surgical procedures, such as percutaneous biopsies, may also be performed for the sole purpose of obtaining tissue specimens or biological fluids for this protocol. Tissues and biological fluids to be procured may include but are not limited to blood, serum, urine, tumor tissue, normal tissue, pleural fluid, CSF, saliva, bronchial alveolar lavage (BAL), circulating tumor cells, hair follicles, and bone marrow. These specimens will be stored with unique identifiers and used to perform only those research studies that are outlined in this protocol. * For pediatric patients: tumor biopsy/resection tissue used for pediatric preclinical model development will only be from tissue already being obtained as part of a procedure necessary for the patient s clinical care or as part of a primary research protocol; blood specimens will be collected as part of a blood collection already scheduled for the patient s clinical care or as part of the planned pre-procedure bloodwork; volumes collected will not exceed institutional research limits. * Given the risks associated with any invasive procedure, such as tumor biopsy, the procedure will be discussed in detail with the patients and their parents/guardian (as indicated), including the side effects, prior to obtaining a separate consent for each procedure. A separate consent will not be signed prior to obtaining samples by minimally invasive measures, such as venipuncture. * This study has two separate consent forms at the NIH Clinical Center: one for adult patients to donate specimens for ongoing research on assay development and studies of molecular pathways, and one for adult and age-appropriate pediatric patients to donate samples for the generation of preclinical models. The study also has consent form templates for adult and pediatric patients at participating sites to donate specimens to create preclinical models. * Patients may remain on study for the duration of their consent or completion of the planned procedure, whichever comes first.

Cord Blood Transplant, Cyclophosphamide, Fludarabine, and Total-Body Irradiation in Treating Patients With High-Risk Hematologic Diseases

This phase II trial studies how well giving an umbilical cord blood transplant together with cyclophosphamide, fludarabine, and total-body irradiation (TBI) works in treating patients with hematologic diseases. Giving chemotherapy, such as cyclophosphamide, fludarabine and thiotepa, and TBI before a donor cord blood transplant (CBT) helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after transplant may stop this from happening in patients with high-risk hematologic diseases.

CMV-MVA Triplex Vaccination in HLA-Matched Related Stem Cell Donors for the Prevention of CMV Infection in Patients Undergoing Hematopoietic Stem Cell Transplant

This phase II clinical trial tests how well the cytomegalovirus-modified vaccinica Ankara (CMV-MVA) Triplex vaccine given to human leukocyte antigens (HLA) matched related stem cell donors works to prevent cytomegalovirus (CMV) infection in patients undergoing hematopoietic stem cell transplant. The CMV-MVA Triplex vaccine works by causing an immune response in the donors body to the CMV virus, creating immunity to it. The donor then passes that immunity on to the patient upon receiving the stem cell transplant. Giving the CMV-MVA triplex vaccine to donors may help prevent CMV infection of patients undergoing stem cell transplantation.

A Vaccine (CMV-MVA Triplex Vaccine) for the Enhancement of CMV-Specific Immunity and the Prevention of CMV Viremia in Patients Undergoing Haploidentical Hematopoietic Stem Cell Transplant

This phase Ib trial tests the safety, side effects, and how well cytomegalovirus (CMV)-modified vaccinia Ankara (MVA) Triplex vaccine works in enhancing CMV-specific immunity and preventing CMV viremia in patients undergoing haploidentical hematopoietic stem cell transplant. Haploidentical stem cell transplantation (haploHCT) has advanced to become the predominant procedure for patients lacking a matched donor. Compared to matched related donor transplants, the rate of significant CMV infection is higher in patients undergoing a haploHCT. Significant CMV infection is associated with an increased risk of complications and death. Vaccination is the main preventative approach to limit complications and death in immunocompromised patients at high risk of post-stem cell transplant infections. CMV-MVA Triplex vaccine, is a CMV vaccine based on the attenuated poxvirus, modified vaccinia Ankara (MVA), developed to enhance CMV-specific immunity in both healthy stem cell transplant donors and stem cell transplant patients to prevent significant CMV infection post-stem cell transplant. Giving CMV-MVA triplex vaccine may be safe, tolerable and/or effective in enhancing cytomegalovirus (CMV)-specific immunity and preventing CMV viremia in patients undergoing a haploHCT.

Induction and Consolidation With Fludarabine, Cytarabine, Idarubicin, and Venetoclax for the Treatment of Acute Myeloid Leukemia

This phase II trial compares induction and consolidation therapy with fludarabine, cytarabine, idarubicin, and venetoclax to cytarabine and daunorubicin induction and cytarabine consolidation for the treatment of acute myeloid leukemia (AML). Patients with AML often receive induction and consolidation therapy. Induction therapy is given first to get the patient's AML under control (remission). Consolidation therapy is given after the cancer has disappeared following the initial therapy. Consolidation therapy is used to kill any cancer cells that may be left in the body. Chemotherapy drugs, such as fludarabine, cytarabine, idarubicin, and daunorubicin, 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. 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. Giving fludarabine, cytarabine, idarubicin, and venetoclax for induction and consolidation therapy may be more effective in treating AML.

Graft Versus Host Disease-Reduction Strategies for Donor Blood Stem Cell Transplant Patients With Acute Leukemia or Myelodysplastic Syndrome (MDS)

This phase II trial investigates two strategies and how well they work for the reduction of graft versus host disease in patients with acute leukemia or MDS in remission. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem 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. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells.

Total Marrow and Lymphoid Irradiation as Conditioning Regimen Before Hematopoietic Cell Transplantation in Patients With Myelodysplastic Syndrome or Acute Leukemia

This phase II trial studies how well total marrow and lymphoid irradiation works as a conditioning regimen before hematopoietic cell transplantation in patients with myelodysplastic syndrome or acute leukemia. Total body irradiation can lower the relapse rate but has some fatal side effects such as irreversible damage to normal internal organs and graft-versus-host disease (a complication after transplantation in which donor's immune cells recognize the host as foreign and attack the recipient's tissues). Total body irradiation is a form of radiotherapy that involves irradiating the patient's entire body in an attempt to suppress the immune system, prevent rejection of the transplanted bone marrow and/or stem cells and to wipe out any remaining cancer cells. Intensity-modulated radiation therapy (IMRT) is a more recently developed method of delivering radiation. Total marrow and lymphoid irradiation is a method of using IMRT to direct radiation to the bone marrow. Total marrow and lymphoid irradiation may allow a greater dose of radiation to be delivered to the bone marrow as a preparative regimen before hematopoietic cell transplant while causing less side effects to normal organs than standard total body irradiation.
