Filter by:This study is a non-interventional, specimen collection translational study to evaluate vitamin C levels in the peripheral blood of Acute Myeloid Leukemia (AML), Myelodysplastic Syndrome (MDS), or Chronic Myelomonocytic Leukemia (CMML) patients.
This research study is studying a targeted therapy drug as a possible treatment for IDH2 mutant acute myeloid leukemia or chronic myelomonocytic leukemia while undergoing hematopoietic stem cell transplantation. The drug involved in this study is: -Enasidenib.
Myelodysplastic Syndrome (MDS) is a group of blood disorders where the bone marrow does not produce enough mature red blood cells, white blood cells and platelets. In a healthy person, the bone marrow makes blood stem cells (immature cells, also called 'blasts') that become mature blood cells over time. In people with MDS, this process is affected and immature blood cells in the bone marrow do not mature fully to become healthy blood cells. This causes a lack of healthy blood cells that can function properly. With fewer healthy blood cells, infection, anaemia, or easy bleeding may occur. MDS can progress to acute myeloid leukaemia in 25-30% of patients, and if untreated it can be rapidly fatal. The purpose of this study is to evaluate the standard treatment, azacitidine (Vidaza) given as an injection under the skin compared to the same medication (called CC-486) taken as a tablet by mouth. Vidaza is approved by the Australian Therapeutics Goods Administration (TGA) as standard treatment for MDS. CC-486 is an experimental treatment. This means it is not an approved treatment for MDS in Australia. CC-486 is being developed to increase convenience and make it easier for patients to continue their treatment. So far it has been given to over 870 patients in studies across the world. The treatment in the injection and the tablet is the same. Studies like this one are being done to ensure the tablet works in the same way as the standard injected treatment. Vidaza is given by subcutaneous injection (ie under the skin) over an hour for 7 days every 4 weeks for as long as it continues to work. All study participants will receive active treatment (there is no placebo), and all participants will receive the standard injection for six treatment cycles followed by the new tablet medication taken once daily for 21 days every 4 weeks. This allows the researchers to compare the two ways of giving the medicine.
This phase II trial studies the effect of ascorbic acid and combination chemotherapy in treating patients with lymphoma that has come back (recurrent) or does not respond to therapy (refractory), clonal cytopenia of undetermined significance and chronic myelomonocytic leukemia (CMML). Ascorbic acid may make cancer cells more sensitive to chemotherapy. Drugs used in chemotherapy, 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 ascorbic acid and combination chemotherapy may kill more cancer cells.
This phase II trial studies how well venetoclax and decitabine work in treating participants with acute myeloid leukemia that has come back or does not respond to treatment, or with high-risk myelodysplastic syndrome that has come back. Drugs used in chemotherapy, such as venetoclax 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.
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.
Myelodysplastic syndromes (MDS) constitute a heterogeneous group of clonal bone marrow neoplasms that predominate in the elderly, with a median age at diagnosis of 70 years. MDS are characterized by peripheral blood cytopenia and morphologic dysplasia for one or more hematopoietic cell lineage, reflecting ineffective hematopoiesis. The diagnostic work-up of MDS includes a bone marrow aspirate and biopsy, which is an invasive procedure, for cytomorphologic and cytogenetic evaluations. Because the prevalence of disease is lower than 20% in subjects referred for suspected MDS, many patients are exposed to unnecessary bone marrow aspiration-related discomfort and harms. An objective assay is highly desirable for accurately ruling out MDS based on peripheral blood samples, which may obviate the need for invasive bone marrow aspiration and biopsy in patients with negative results. Few studies have investigated the value of peripheral blood flow cytometric analysis for the diagnosis of MDS and/or chronic myelomonocytic leukemia (CMML). Although promising, these studies lacked replication of their results, used a case-control design, which was prone to spectrum bias, or yielded imprecise diagnostic accuracy estimates due to relatively limited sample sizes. Anecdotal evidence supports the potential of flow cytometric analysis of peripheral blood neutrophil myeloperoxidase expression for the diagnosis of MDS and CMML. Myeloperoxidase is an enzyme synthetized during myeloid differentiation that constitutes the major component of neutrophil azurophilic granules. Myeloperoxidase expression may reflect neutrophil hypogranulation, which is a classical although subjective dysplastic feature of MDS. Flow cytometric analysis of myeloperoxidase expression in bone marrow neutrophil granulocytes has been used for discriminating low versus high grade MDS. Yet a study reporting on the accuracy of flow cytometric analysis of peripheral blood neutrophil myeloperoxidase expression for the diagnosis of MDS is still lacking, to our knowledge. In this study, the investigators hypothesize that flow cytometric analysis of neutrophil myeloperoxidase expression in peripheral blood may accurately rule out MDS and obviate the need for bone marrow aspiration and biopsy, with sensitivity approaching 100%, in routine practice. In this observational diagnostic accuracy study, burden will be null for recruited patients. No specific intervention is assigned to participants. All diagnostic testing, procedures, and medication ordering are performed at the discretion of attending physicians. Flow cytometry analysis of peripheral blood neutrophil myeloperoxidase expression will not require additional blood sample. A test result will have no impact on patient management. No follow-up visits are planned in this cross-sectional study.
This phase I trial studies the side effects of DEC-205/NY-ESO-1 fusion protein CDX-1401, poly ICLC, decitabine, and nivolumab in treating patients with myelodysplastic syndrome or acute myeloid leukemia. DEC-205/NY-ESO-1 fusion protein CDX-1401 is a vaccine that may help the immune system specifically target and kill cancer cells. Poly ICLC may help stimulate the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as 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. Monoclonal antibodies, such as nivolumab, may interfere with the ability of cancer cells to grow and spread. Giving DEC-205/NY-ESO-1 fusion protein CDX-1401, poly ICLC, decitabine, and nivolumab may work better in treating patients with myelodysplastic syndrome or acute myeloid leukemia.
This phase II trial studies how well fludarabine phosphate, cyclophosphamide, total body irradiation, and donor stem cell transplant work in treating patients with blood cancer. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, 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 to kill cancer cells and shrink tumors. 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.
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.
