Filter by:Immune thrombocytopenia (ITP) is an autoimmune disease but, paradoxically, and unlike other autoimmune diseases, antiplatelet antibodies are not used either for the diagnosis of the disease or for its prognosis. ITP is a diagnosis of exclusion retained after elimination of other pathologies leading to a thrombocytopenia. No major study has prospectively evaluated the diagnostic value of the presence of anti-platelet antibodies in the etiological investigation of a thrombocytopenia, nor the impact of platelet antibodies on the course of ITP. The gold standard analysis for the determination of platelet antibodies, is the "monoclonal antibody immobilization of platelet antigens" assay (MAIPA), either direct to detect autoantibodies attached to platelets, or indirect to detect circulating antiplatelet antibodies. Therefore, this work aims to study the contribution of the presence of anti-platelet antibodies detected in MAIPA to determine the autoimmune nature of a thrombocytopenia at diagnosis.
This study is a multi-institution, open-label, Phase 1b/2 clinical trial evaluating the toxicity and efficacy of canakinumab in combination with darbepoetin alfa in patients with lower-risk MDS who have failed prior treatment with an Erythropoietin Stimulating Agent (ESA)
This study compares the efficacy of Tamibarotene in combination with azacitidine to azacitidine in combination with placebo in participants who are Retinoic Acid Receptor Alpha (RARA) positive, and newly diagnosed with higher-risk myelodysplastic syndrome (HR-MDS), and who have not received treatment for this diagnosis. The primary goal of the study is to compare the complete remission rate between the two treatment arms.
This study is designed to evaluate the efficacy and safety of eltrombopag monotherapy in Japanese adult patients with platelet transfusion-dependent lower-risk Myelodysplastic syndromes (LR-MDS).
This is a Phase 1, multi-center, open-label study with a dose-escalation phase (Phase 1a) and a cohort expansion phase (Phase 1b), to evaluate the safety, tolerability, and PK profile of LP-118 under a once daily oral dosing schedule in up to 100 subjects.
This is a single-arm pilot study of the feasibility and safety of metformin in patients with clonal cytopenia of undetermined significance (CCUS) or lower-risk myelodysplastic neoplasms (LR-MDS).
This phase I/II trial identifies the best dose of seclidemstat when given together with azacitidine in treating patients with myelodysplastic syndrome or chronic myelomonocytic leukemia. Seclidemstat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Azacitidine may help block the formation of growths that may become cancer. Giving seclidemstat and azacytidine may kill more cancer cells.
This study aims to use clinical and biological characteristics of acute leukemias to screen for patient eligibility for available pediatric leukemia sub-trials. Testing bone marrow and blood from patients with leukemia that has come back after treatment or is difficult to treat may provide information about the patient's leukemia that is important when deciding how to best treat it, and may help doctors find better ways to diagnose and treat leukemia in children, adolescents, and young adults.
Myelodysplastic syndromes (MDS) are malignant hematopathies of the elderly characterized by persistent cytopenias and the presence of deregulated clonal hematopoiesis. The risk of progression to acute myeloid leukemia (AML) is variable. Acquired cytogenetic abnormalities are found in less than 50% of de novo cases and up to 80% in secondary MDS. The deletion of the long arm of chromosome 5 (written del(5q)) is the most common abnormality in MDS (15%). Del(5q) MDS has a good prognosis, with a median survival of 6 years and a 15% risk of progression to AML. However, their life expectancy is shorter than the general population, and the quality of life of patients is diminished. These treatments are not that effective over a long period of time or not well tolerated, and the majority of patients die from causes related to their MDS, such as infections (38%), progression to AML (15%), or bleeding (13%). Two genes, RBM22 and SLU7, coding for proteins of the same complex involved in splicing pre-messenger RNA are carried on the long arm of chromosome 5. We investigate the pronostic impact and the predictive value of the double haploinsufficiency of the RBM22 and SLU7 genes in del(5q) myelodysplastic syndromes isolated or not compared to the single haploinsufficiency of RBM22 and normal karyotype myelodysplastic syndromes.
This research study is evaluating the safety and efficacy of the IS-free Treg-cell graft-engineered haplo transplant method in people with relapsed/refractory and Ultra-high risk acute myeloid leukemia (AML) and/or myelodysplastic syndromes (MDS) receiving a haploidentical donor allogeneic hematopoietic stem cell transplant (HSCT). The names of the study interventions involved in this study are: - Radiation-Total Myeloid and Lymphoid Irradiation (TMLI - Chemotherapy (Fludarabine, Thiotepa, Cyclophosphamide plus Mesna) - Infusion of haplo Treg-enriched donor cells (experimental therapy) - Infusion of unmodified haplo donor T cells (includes cancer-fighting T effector cells) - Infusion of haplo donor CD34+ Peripheral Blood Stem Cells
