A Randomized Study of ASTX727 With or Without Iadademstat in Advanced Myeloproliferative Neoplasms (MPNs)
Description

This phase II trial compares the effect of ASTX727 in combination with iadademstat to ASTX727 alone in treating patients with accelerated or blast phase Philadelphia chromosome negative myeloproliferative neoplasms (MPNs). ASTX727 is a combination of two drugs, cedazuridine and decitabine. 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. 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. Iadademstat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving ASTX727 in combination with iadademstat may be more effective than ASTX727 alone in treating patients with accelerated or blast phase Philadelphia chromosome negative MPNs.

COMPLETED
PD-1 Inhibition in Advanced Myeloproliferative Neoplasms
Description

The purpose of this study is to test the effectiveness of a drug called pembrolizumab in patients with Myeloproliferative Neoplasm (MPN); chronic phase (MF-CP), accelerated phase (MPN-AP), or blast phase (MF-BP). Myelofibrosis neoplasm (MPN) is a group of diseases of the bone marrow in which excessive cells are produced. Pembrolizumab also known as Keytruda is a drug that has recently been approved in the United Stated by the Food and Drug Administration (FDA) for the treatment of patients with unresectable or metastatic melanoma and disease progression. Pembrolizumab is experimental in the treatment of MPN. The researchers want to find out what effects, good and /or bad it has on participants and the disease. Participants qualify to take part in this research study if have been diagnosed with a MPN blood disorder called myelofibrosis (MF). Accelerated (10-19% blasts in the blood or bone marrow) and blast phase (\>20% blasts in the blood or bone marrow) MPN has been a difficult disease to treat. The term "blasts" refers to immature cells found in the bone marrow. They are not fully developed, and therefore, do not yet carry out any particular function within the body. Funds for conducting this research are provided by Merck and Company, the manufacturer of the study drug pembrolizumab.

COMPLETED
Clofarabine, Cytarabine, and Filgrastim in Treating Patients With Newly Diagnosed Acute Myeloid Leukemia, Advanced Myelodysplastic Syndrome, and/or Advanced Myeloproliferative Neoplasm
Description

This phase II trial is studying how well giving clofarabine and cytarabine together with filgrastim works in treating patients with newly diagnosed acute myeloid leukemia (AML), advanced myelodysplastic syndrome (MDS), and/or advanced myeloproliferative neoplasm. Drugs used in chemotherapy, such as clofarabine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving the drugs in different doses may kill more cancer cells. Colony stimulating factors, such as filgrastim, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy.

SUSPENDED
Axatilimab with or Without Azacitidine for the Treatment of Patients with Advanced Phase Myeloproliferative Neoplasms, Myeloproliferative Neoplasm/Myelodysplastic Syndrome Overlap or High Risk Chronic Myelomonocytic Leukemia
Description

This phase Ib/II trial tests the best dose of axatilimab and effectiveness of axatilimab with or without azacitidine for the treatment of patients with advanced phase myeloproliferative neoplasms (MPN), myeloproliferative neoplasm/myelodysplastic syndrome (MPN/MDS) overlap or high risk chronic myelomonocytic leukemia (CMML). Axatilimab is an antibody that is cloned from a single white blood cell that is known to be able to recognize cancer cells and block a protein on the surface of the white blood cells that may be involved in cancer cell growth. By blocking the proteins, this may slow or halt the growth of the cancer. Azacitidine is in a class of medications called antimetabolites. It works by stopping or slowing the growth of cancer cells. Giving axatilimab with or without azacitidine may be safe and effective in treating patients with advanced phase MPN, MPN/MDS overlap or high risk CMML.

Testing the Effect of Taking Ruxolitinib and CPX-351 in Combination for the Treatment of Advanced Phase Myeloproliferative Neoplasms
Description

This phase I/II trial studies the best dose of ruxolitinib when given together with CPX-351 and to see how well they work in treating patients with accelerated phase or blast phase myeloproliferative neoplasm. Ruxolitinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. CPX-351 is a mixture of 2 chemotherapy drugs (daunorubicin and cytarabine) given for leukemia in small fat-based particles (liposomes) to improve the drug getting into cancer cells. Giving ruxolitinib and CPX-351 may work better in treating patients with secondary acute myeloid leukemia compared to CPX-351 alone.

Safety and Efficacy of BL-8040 for the Mobilization of Donor Hematopoietic Stem Cells and Allogeneic Transplantation in Patients With Advanced Hematological Malignancies
Description

Current protocols use G-CSF to mobilize hematopoietic progenitor cells from matched sibling and volunteer unrelated donors. Unfortunately, this process requires four to six days of G-CSF injection and can be associated with side effects, most notably bone pain and rarely splenic rupture. BL-8040 is given as a single SC injection, and collection of cells occurs on the same day as BL-8040 administration. This study will evaluate the safety and efficacy of this novel agent for hematopoietic progenitor cell mobilization and allogeneic transplantation based on the following hypotheses: * Healthy HLA-matched donors receiving one injection of BL-8040 will mobilize sufficient CD34+ cells (at least 2.0 x 10\^6 CD34+ cells/kg recipient weight) following no more than two leukapheresis collections to support a hematopoietic cell transplant. * The hematopoietic cells mobilized by SC BL-8040 will be functional and will result in prompt and durable hematopoietic engraftment following transplantation into HLA-identical siblings with advanced hematological malignancies using various non-myeloablative and myeloablative conditioning regimens and regimens for routine GVHD prophylaxis. * If these hypotheses 1 and 2 are confirmed after an interim safety analysis of the data, then the study will continue and include recruitment of haploidentical donors.

COMPLETED
The First-in-human Phase I Trial of PU-H71 in Patients With Advanced Malignancies
Description

NOTE: This study is now recruiting only patients with Myeloproliferative Neoplasms (MPN). Dose escalation has been completed. The purpose of this study is to test a new drug, called PU-H71 for the first time in humans, to find out what effects, good or bad, this new drug has on the patient and the cancer at different dose levels. PU-H71 blocks a protein called Heat Shock Protein-90 (Hsp90). Hsp90 is found in both normal and cancer cells, but may be more important in cancer cells. Attacking Hsp90 can stop the function of certain proteins that are needed for cancer cells to survive. The diseases that are part of this study may be especially sensitive to attacking Hsp90, and the investigators have seen signs of disease control in patients with MPN. This study is currently enrolling a cohort expansion for patients with myeloproliferative neoplasms (MPN).
