Filter by:This is a multi-center, Phase II, cross-sectional study comparing quality of life (QOL) as assessed by patient-reported outcomes (PROs) in older (≥65 years) adults vs younger (55-64 years) undergoing allogeneic hematopoietic cell transplantation (HCT) for myelodysplastic syndromes (MDS).
The purpose of this observational study is to provide data on the incidence and severity of infusion-related reactions during and immediately following each infusion of VYXEOS during the first induction.
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.
An open label, Phase 1, study of AMV564 as monotherapy to assess the safety and efficacy in patients with Myelodysplastic Syndromes
To assess tolerability of SyB C-1101 when administered orally BID for 21 days followed by a 7-day observation period in patients with recurrent/relapsed or refractory myelodysplastic syndrome in order to determine a recommended dose (RD). To assess safety, efficacy and pharmacokinetics.
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.
Current diagnostic criteria for Immune ThrombocytoPenia (ITP) are mainly based on the presence of low numbers of platelets, excluding other multiple causes of thrombocytopenia, including immunodeficiencies, constitutional or acquired thrombocytopenia, hypersplenism and clonal hematological disorders such as MDS, disorders lymphoproliferative and acute myeloid leukemia (AML), among others. The analysis complementary tests for the diagnosis of ITP include studies basic systematic hematology, together with autoimmune assays and microbiological tests, while the evaluation of bone marrow is limited to elderly patients and/or patients resistant to treatment. Previous research has described the development of Myelodysplastic Syndrome (MDS) in patients with a previous diagnosis of ITP, and even the presence of MDS associated with genetic background. Therefore, it is conceivable fact that a percentage of cases with clinical signs of ITP in the moment of appearance may actually correspond to the first stages of MDS development in which bone marrow cells are not systematically evaluated in the initial presentation. The anomalous immunophenotypic patterns between multiple compartments of bone marrow cells and peripherally blood (PB) platelets have been characterized through flow cytometry. The flow cytometry currently represents an important complementary tool for diagnosis of MDS that has shown great effectiveness and applicability in the differential diagnosis of non-clonal cytopenias against early MDS and for the detection of stages prior to MDS. Besides, the flow cytometry has made it possible to detect the presence of coexisting features related to MDS in patients with other malignancies hematologic conditions such as multiple myeloma, AML, and lymphocytic leukemia chronic. Therefore, the immunophenotypic analysis of the cells of the bone marrow of patients with ITP at the time of appearance would help to identify the cases that underlie clonal hematopoiesis MDS type. In the present study it is planned a broad characterization immunophenotyping of multiple compartments of bone marrow cells and PB platelets from patients with recently diagnosed ITP and investigate their morphological antecedents, in order to identify those patients who show compatible clonal hematopoietic patterns with MDS evident (or at risk of development), as candidates to receive most appropriate therapeutic methods.
The investigators hypothesize that the combination of Pevonedistat/Low-Dose Cytarabine (LDAC) therapy will be tolerable, that a recommended phase 2 dose of Pevonedistat in combination with LDAC will be identified, and that the combination therapy will show evidence of clinical activity in adult patients with Relapsed/Refractory Acute Myelogenous Leukemia (AML) and Advanced Myelodysplastic Syndromes (MDS).
SIR-POSA is a phase II trial of peripheral blood stem cell (PBSC) transplantation from a partially compatible family (Haplo) donor in patients with a blood tumor (myelodysplastic syndrome (MDS) and acute leukemia) treated for the prevention of primary fungal infections with posaconazole. The aim is evaluate the composite end-point graft-versus-host disease-free, relapse-free survival (GRFS) in these patients and evaluate the feasibility and efficacy of posaconazole oral tablets as primary antifungal prophylaxis.
This is an open label, Phase Ib study designed to evaluate the safety, toxicity and biological activity of high dose Vitamin C in bone marrow and peripheral blood when administered as therapy to patients with intermediate or high risk myelodysplastic syndrome according to the revised IPSS (international prognostic scoring system) criteria whose disease has a Ten-eleven translocation-2, (TET2) mutation. The primary objectives phase 1 study is to establish safety and confirm a steady level of Vitamin C on ≥1 mM in > 75% of the patients is achieved. All patients will receive at least 1 cycle of treatment (4 weeks). Patients with clinical benefit (CR,PR, or SD) then will undergo a second 4-week cycle of treatment.
