Filter by:RATIONALE: Conditioning with total body irradiation (TBI) and fludarabine, cyclophosphamide and anti-thymocyte globulin may induce the engraftment cross the immunologic barrier in the setting of HLA-haploidentical allogeneic hematopoietic cell transplantation. In addition, T-cell depletion may contribute to prevent developing severe acute graft versus host disease (GVHD) in haploidentical transplantation. PURPOSE: This phase I/II trial is to evaluate the safety and efficacy of TBI, fludarabine, cyclophosphamide and antithymocyte globulin with T-cell depleted graft from haploidentical donors in treating patients with acute leukemia and myelodysplastic syndrome.
This study is being performed to develop assays to determine the impact of the therapy patients receive for treatment of AML or MDS and to determine if these tests can identify those patients who are at a greater risk for having their disease relapse.
The present study is designed to determine the mutational status of markers (TET2 and PLCb2, cytogenetic aberrations) together with methylation status of the above genes using bone marrow and matched buccal cell samples from MDS patients who necessitate to start a treatment (i.e. EPO, Lenalidomide, Azacytidine). All patients included in the study will be followed for at least 2 years.
To evaluate the feasibility and efficacy of the conditioning regimen with cyclophosphamide, fludarabine and antithymocyte globulin (CyFluATG) for allogeneic hematopoietic cell transplantation (HCT) in patients with lower risk myelodysplastic syndrome (MDS).
The purpose of this study is to evaluate the feasibility and efficacy of reduced-intensity conditioning allogeneic HCT followed by prophylactic dose-escalating DLIs in patients with higher risk MDS.
This is a registry study in adult patients with newly diagnosed or refractory/relapsed myeloid neoplasms Investigator's sites: 60-70 sites in Germany and Austria Estimated duration of observation of an individual patient: 10 years maximum Objectives - To register all patients with acute myeloid leukemia and related precursor neoplasms, acute leukemia of unambiguous lineage, with higher risk myelodysplastic syndromes (MDS with excess blasts 2), and with myeloid neoplasms with germline predisposition, newly diagnosed or relapsed/refractory in all participating centers (completeness) - To perform timely analyses of disease-related genetic markers (incidences, treatment recommendations) - To assess patient and family history, clinical characteristics and outcome data (event-free survival [EFS], cumulative incidence of relapse [CIR], cumulative incidence of death [CID], overall survival [OS]) - To assess biological disease features and correlate with clinical outcome data (prognostic and predictive markers) - To store biosamples from all patients (e.g., bone marrow, blood, plasma, normal tissue, e.g., skin biopsy, buccal swap, finger nails, hairs, or sputum) - To assess quality of life
This is a combination study to evaluate sapacitabine administered in alternating cycles with decitabine in previously untreated Acute Myeloid Leukemia (AML) or concomitantly with venetoclax in previously treated AML or MDS
Myelodysplastic syndromes (MDS) are frequent diseases in elderly patients (median age: 71 years). IPSS classification defines low risk (Low and Intermediate 1), and high risk (Intermediate 2 and High) MDS. High-risk MDS (MDS-HR) have a high risk of transformation into acute leukemia with multilineage dysplasia (AML-DML). The success of Azacitidine has been mainly achieved through a rigorous empirical and clinical research, but the molecular mechanisms by which this molecule exerts its effects remain poorly characterized. The primary mode of action of Azacytidine is through DNA demethylation, and integration in to mRNA that favor traduction inhibition. The impact of this molecule on various cell death programs involved in the elimination of leukemic cells : apoptosis and autophagy is currently poorly known. The research program and clinical studies we proposed focus on two major aspects: - Main objective: Molecular mechanism of action and resistance to Azacitidine: Role of apoptosis versus autophagy. - Secondary Objective: Reversion of Azacytidine resistance using different drugs targeting apoptosis and/or autophagy. Our laboratory has identified new molecules to selectively induce different types of cell death (apoptosis or autophagy).
Background: - Stem cell transplants from related donors (allogenic stem cell transplants) can be used to treat individuals with certain kinds of severe blood diseases or cancers, such as severe anemia. Allogenic stem cell transplants encourage the growth of new bone marrow to replace that of the recipient. Because stem cell transplants can have serious complications, researchers are interested in developing new approaches to stem cell transplants that will reduce the likelihood of these complications. - By reducing the number of white blood cells included in the blood taken during the stem cell collection process, and replacing them with a smaller amount of white blood cells collected prior to stem cell donation, the stem cell transplant may be less likely to cause severe complications for the recipient. Researchers are investigating whether altering the stem cell transplant donation procedure in this manner will improve the likelihood of a successful stem cell transplant with fewer complications. Objectives: - To evaluate a new method of stem cell transplantation that may reduce the possibly of severe side effects or transplant rejection in the recipient. Eligibility: - Recipient: Individuals between 4 and 80 years of age who have been diagnosed with a blood disease that can be treated with allogenic stem cell transplants. - Donor: Individuals between 4 and 80 years of age who are related to the recipient and are eligible to donate blood. OR unrelated donors found through the National Marrow Donor Program. Design: - All participants will be screened with a physical examination and medical history. - DONORS: - Donors will undergo an initial apheresis procedure to donate white blood cells. - After the initial donation, donors will receive injections of filgrastim to release bone marrow cells into the blood. - After 5 days of filgrastim injections, donors will have apheresis again to donate stem cells that are present in the blood. - RECIPIENTS: - Recipients will provide an initial donation of white blood cells to be used for research purposes only. - From 7 days before the stem cell transplant, participants will be admitted to the inpatient unit of the National Institutes of Health Clinical Center and will receive regular doses of cyclophosphamide, fludarabine, and anti-thymocyte globulin to suppress their immune system and prepare for the transplant. - After the initial chemotherapy, participants will receive the donated white blood cells and stem cells as a single infusion. - After the stem cell and white blood cell transplant, participants will have regular doses of cyclosporine and methotrexate to prevent rejection of the donor cells. Participants will have three doses of methotrexate within the week after the transplant, but will continue to take cyclosporine for up to 4 months after the transplant. - Participants will remain in inpatient care for up to 1 month after the transplant, and will be followed with regular visits for up to 3 years with periodic visits thereafter to evaluate the success of the transplant and any side effects.
This research study is studying identification of de novo Fanconi anemia in younger patients with newly diagnosed acute myeloid leukemia. Studying samples of tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to Fanconi anemia in patients with acute myeloid leukemia.
