Active clinical trials for "Leukemia, Myelomonocytic, Juvenile"

The major morbidities of allogeneic hematopoietic stem cell transplant with non-human leukocyte antigen (HLA) matched siblings are graft vs host disease (GVHD) and life threatening infections. T depletion of the donor hematopoietic stem cell graft is effective in preventing GVHD, but immune reconstitution is slow, increasing the risk of infections. An addback of donor CD45RA (naive T cells) depleted cells may improve immune reconstitution and help decrease the risk of infections.

This phase II trial studies the side effects and how well azacitidine and enasidenib work in treating patients with IDH2-mutant myelodysplastic syndrome. Azacitidine and enasidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Patients less than or equal to 21 years old with high-risk hematologic malignancies who would likely benefit from allogeneic hematopoietic cell transplantation (HCT). Patients with a suitable HLA matched sibling or unrelated donor identified will be eligible for participation ONLY if the donor is not available in the necessary time. The purpose of the study is to learn more about the effects (good and bad) of transplanting blood cells donated by a family member, and that have been modified in a laboratory to remove the type of T cells known to cause graft-vs.-host disease, to children and young adults with a high risk cancer that is in remission but is at high risk of relapse. This study will give donor cells that have been TCRαβ-depleted. The TCR (T-cell receptor) is a molecule that is found only on T cells. These T-cell receptors are made up of two proteins that are linked together. About 95% of all T-cells have a TCR that is composed of an alpha protein linked to a beta protein, and these will be removed. This leaves only the T cells that have a TCR made up of a gamma protein linked to a delta protein. This donor cell infusion will be followed by an additional infusion of donor memory cells (CD45RA-depleted) after donor cell engraftment. This study will be testing the safety and effects of the chemotherapy and the donor blood cell infusions on the transplant recipient's disease and overall survival.

This research is being done to see if the drug Inqov is effective in reducing the chance of myelodysplastic syndrome (MDS) or chronic myelomonocytic leukemia (CMML) relapsing after standard of care stem cell transplant. This research study involves the study drug Inqovi, which is a combination of the drugs decitabine and cedazuridine.

This phase I/II trial studies the side effects and best dose of venetoclax in combination with cedazuridine and decitabine (ASTX727) in treating patients with high risk myelodysplastic syndrome or chronic myelomonocytic leukemia who have not received prior treatment (treatment-naive). Chemotherapy drugs, such as venetoclax, cedazuridine, and decitabine, 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.

The purpose of this study is to determine if hyperbaric oxygen therapy is safe in the setting of stem cell transplantation. This study will also determine if hyperbaric oxygen therapy improves engraftment, graft versus host disease, neutrophil count, and incidence and severity of mucositis (inflammation of the mouth or gut) and infection. This study has two cohorts. The first cohort is subjects with acute myeloid leukemia (AML) or Myelodysplastic Syndrome (MDS). The second cohort is subjects with chronic myelomonocytic leukemia (CMML), atypical chronic myeloid leukemia (aCML), chronic monocytic leukemia, chronic neutrophilic leukemia (CNL), myelofibrosis, and myelodysplastic/myeloproliferative (MDS/MPN) overlap syndrome. The first cohort has completed the recruitment so only the second cohort will be recruited.

This phase II trial tests whether decitabine and cedazuridine (ASTX727) in combination with venetoclax work better than ASTX727 alone at decreasing symptoms of bone marrow cancer in patients with chronic myelomonocytic leukemia (CMML), myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN) with excess blasts. Blasts are immature blood cells. 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. Cobimetinib is used in patients whose cancer has a mutated (changed) form of a gene called BRAF. It is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells. 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. The combination of ASTX727 and venetoclax may be more effective in reducing the cancer signs and symptoms in patients with CMML, or MDS/MPN with excess blasts.

To learn if the combination of cladribine, cytarabine, venetoclax, and azacitidine can help to control higher-risk myelodysplastic syndrome (MDS) with excess blasts and/or higher-risk chronic myelomonocytic leukemia (CMML).

In this study, tagraxofusp (Tag) is given to patients with CD 123+ myelofibrosis (MF), chronic myelomonocytic leukemia (CMML), and acute myeloid leukemia (AML) after allogeneic stem cell transplant (HCT) to help prevent relapse. Patients will receive up to about 9 cycles of treatment with Tag and have a bone marrow biopsy after cycle 4 and about 1 year after HCT.

This study seeks to examine treatment therapy that will reduced regimen-related toxicity and relapse while promoting rapid immune reconstitution with limited serious graft-versus-host-disease (GVHD) and also improve disease-free survival and quality of life. The investigators propose to evaluate the safety and efficacy of selective naive T-cell depleted (by TCRɑβ and CD45RA depletion, respectively) haploidentical hematopoietic cell transplant (HCT) following reduced intensity conditioning regimen that avoids radiation in patients with hematologic malignancies that have relapsed or are refractory following prior allogeneic transplantation. PRIMARY OBJECTIVE: To estimate engraftment by day +30 post-transplant in patients who receive TCRɑβ-depleted and CD45RA-depleted haploidentical donor progenitor cell transplantation following reduced intensity conditioning regimen without radiation. SECONDARY OBJECTIVES: Assess the safety and feasibility of the addition of Blinatumomab in the early post-engraftment period in patients with CD19+ malignancy. Estimate the incidence of malignant relapse, event-free survival, and overall survival at one-year post-transplantation. Estimate incidence and severity of acute and chronic (GVHD). Estimate the rate of transplant related mortality (TRM) in the first 100 days after transplantation.
