Filter by:Myelodysplastic syndrome (MDS) is a group of clonal haematopoietic stem cell disorders characterized by ineffective haematopoiesis leading to cytopenia, with a significant risk of progression to acute myeloid leukaemia (AML). Progression to AML and resistance to hypomethylating agents (HMA) are important unmet clinical needs. The pathophysiology of MDS and its progression to AML involve cytogenetic, genetic and epigenetic aberrations, and hence better understanding of the molecular landscape of MDS has important clinical implications. Also, future treatment strategies for MDS may involve exploitation of genetic information in designing more effective therapy encompassing single agents or combinatorial approaches. The proposed cohort study aims to establish a registry of clinical and genomic registry of MDS and secondary AML in Asian patients, which allows the establishment of the mutational profile of patients and prognostic model for survival, as well as exploration of treatment strategies and prediction for treatment response.
This is a prospective phase II clinical study planned to be conducted at the Medical College of Wisconsin (MCW). After meeting the study criteria and enrollment, patients will be treated with a cladribine based salvage regimen and followed at periodic intervals to determine the primary and secondary objectives.
The study is a Phase II clinical trial. Patients will receive intensity modulated total marrow irradiation (TMI) at a dose of 9 Gy with standard myeloablative fludarabine/ i.v. targeted busulfan (FluBu) conditioning prior to allogeneic hematopoietic stem cell transplant (HSCT).
This research study is studying a drug as a possible treatment for diagnosis of AML, BPDCN and high-risk MDS. The interventions involved in this study are: - SL-401 - Azacitidine - Venetoclax
This study will evaluate the safety of infusing an anti-MiHA T cell line in patients suffering from an hematologic malignancy that has relapsed following hematopoietic stem cell transplantation from a matched donor.
Historically, the best results of allogeneic SCT have been obtained when the stem cell donor is a human leukocyte antigen (HLA)-matched sibling, however, this is only available for approximately 30 percent of patients in need for SCT. Alternative donor sources include matched unrelated donor utilizing the donor registry, cord blood transplant and mismatched donor transplant. A human leukocyte antigen (HLA)-haploidentical donor is one who shares, by common inheritance, exactly one HLA haplotype with the recipient, and includes the biologic parents, biologic children and full or half siblings. There is strong body of evidence supporting the use of haplo-SCT in patient who lack a matched sibling or unrelated donor with high rates of successful engraftment, effective Graft Versus Host Disease (GVHD) control and favorable outcomes comparative to those seen using other allograft sources, including HLA-matched sibling SCT. Furthermore, it provides a cost-efficient donor option in a timely manner especially for patients who need to proceed quickly to transplant due to concern of disease relapse/progression.
The purpose of this study is to collect information and bone marrow, blood, saliva, cheek cells and skin to be used in the laboratory to assist the sponsor in identifying a new way of treating MDS.
Myelodysplastic syndrome (MDS) is widely recognized as a clonal hematopoietic stem cell disorder. Decitabine has been approved for the treatment of all subtypes of myelodysplastic syndrome (MDS). However, the use of decitabine is often limited by its severe toxicity represented by myelosuppression even at relatively low doses. In lower-risk patients (including IPSS low and int-1 risk groups), treatment mainly aims at improving cytopenias, especially anemia. However, although several drugs may improve anemia, sometimes durably, most of lower risk MDS eventually require red blood cell (RBC) transfusions during their disease course. Long term RBC transfusions lead to iron overload mainly due to an increase in reticulo-endothelial iron recycling.Cardiac, liver and endocrine (diabetes mellitus) dysfunction due to iron overload and often leading to fatal outcome has been reported in heavily transfused lower risk MDS patients. To date, the optimal regimen for decitabine treatment is not well established. In this study, we perform a prospective analysis to explore the decitabine schedule for the treatment of lower risk myelodysplastic syndrome patients with transfusion dependent.
This phase I trial studies the best dose and side effects of recombinant vesicular stomatitis virus carrying the human NIS and IFN beta genes (VSV-hIFNbeta-sodium iodide symporter [NIS]) with or without cyclophosphamide or ipilimumab and nivolumab or cemiplimab in treating patients with multiple myeloma, acute myeloid leukemia (AML) or lymphoma that has come back or does not respond to treatment. A virus, called VSV-hIFNbeta-NIS, which has been changed in a certain way, may be able to kill cancer cells without damaging normal cells. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill cancer cells. It may also lower the body's immune response. Immunotherapy with ipilmumab and nivolumab or cemiplimab may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving VSV-hIFNbeta-NIS and ruxolitinib phosphate may work better at treating multiple myeloma, acute myeloid leukemia and T-cell lymphoma.
Myelodysplastic Syndromes (MDS) are characterized by quantitative and qualitative bone marrow failure and by a disorder of the medullary production which is a pre-leukemic state which can evolve into acute myeloid leukemia. The risk of leukemic transformation is estimated by the score IPSS (International Prognostic Score System). We distinguish the MDS of low risk (IPSS<1) and those of high risk of leukemic transformation (IPSS=1,5). Besides the risk of leukemic transformation, MDS much be complicated of infections which could be life-threatening. The risk of developing first infection after the diagnosis of MDS of high risk is probably influenced by anamnestic (disease duration, comorbidities), clinical (veinous central catheter, previous hospitalization), biological (neutropenia, lymphopenia, serum ferritin) and therapeutics (demethylating agent, lenalidomide, erythropoietin, G-CSF, transfusions, anti-infectious preventive treatment) factors. Their identification will allow for improved targeting of the population which is is likely to benefit from anti-infective prophylaxis Primary objective is to identify risk factors associated with first acute episode of infection in patients with MDS, by comparing index cases and matched control cases who did not develop infection episode since diagnosis. Secondary objectives are to explore nature and severity of infectious episodes, number of recurrences during 1 year of follow up and survival at 6 and 12 months
