Active clinical trials for "Preleukemia"

Myelodysplastic syndromes (MDS) are chronic myeloid hemopathies characterized by ineffective hematopoiesis (with peripheral cytopenias) and which contrast with a marrow of normal richness. MDS is considered one of the four most common blood diseases. The incidence is estimated at 4,059 cases / year in 2012 with an average age of 78 years in men and 81 years in women (INCA report, Cancers in France in 2015). The incidence increases with lengthening of the lifespan. The main risk of MDS is transformation to acute leukemia in 30 to 40% of cases. Treatment options depend on clinical, hematologic and chromosomal abnormalities. The prognosis is considered to be at low or high risk of developing acute leukemia. This distinction will therefore have an impact on the therapeutic solution (s). MDS exhibit clinical, morphological and genetic heterogeneity. It is therefore necessary to form subgroups of patients to better understand the physiopathogenesis of this pathology. The constitution of a biocollection will make it possible to search for clinical and biological prognostic markers in order to identify patients progressing to acute myeloid leukemia.

To evaluate the 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 efficacy of the treatment will be measured in terms of engraftment and non-relapse mortality (NRM).

The purpose of this Phase I, multicenter, clinical trial is to evaluate the safety of AG-120 and AG-221 when given in combination with standard AML induction and consolidation therapy. The study plans to evaluate up to 2 dose levels of AG-120 in participants with an isocitrate dehydrogenase protein 1 (IDH1) mutation and up to 2 dose levels of AG-221 in participants with an isocitrate dehydrogenase protein 2 (IDH2) mutation. AG-120 or AG-221 will be administered with 2 types of AML induction therapies (cytarabine with either daunorubicin or idarubicin) and 2 types of AML consolidation therapies (mitoxantrone with etoposide [ME] or cytarabine). After consolidation therapy, participants may continue on to maintenance therapy and receive daily treatment with single-agent AG-120 or AG-221 until relapse, development of an unacceptable toxicity, or hematopoietic stem cell transplant (HSCT). The study will end when all participants have discontinued study treatment.

The purpose of this study is to compare safety and efficacy of reduced-intensity conditioning and myeloablative conditioning regimens prior to HSCT in high-risk AML/MDS pediatric and young adult patients. This study investigates the use of two novel conditioning therapies for hematopoietic stem cell transplant (HSCT). The primary focus of both the investigators' myeloablative and reduced-intensity conditioning regimens is to reduce overall toxicity so that pediatric and young adult patients with high-risk AML/MDS with significant pretransplant comorbidities who would have been ineligible to proceed to HSCT previously can now receive potentially life-saving treatment.

<Part I - Phase I trial> The phase I clinical trial is to identify the MTD (Maximum Tolerated Dose) and DLT (Dose Limiting Toxicity) of CG200745 PPA. Initial dose of CG200745 PPA is 150 mg/m^2, and it will be extended to 225 mg/m^2, 300 mg/m^2 or it will be reduced to 75 mg/m^2 based on the results of the cohort of 3 to 6 subjects per dose level. Based on the 3+3 dose escalation study design, CG200745 PPA is to be administered according to the dose level. Each cohort consists of 3 or 6 subjects. <Part II - Phase II trial> In the phase II clinical trial, the subjects will be administered with the dose which is to be identified as a recommended dose based on the results of Phase I study. Each cycle consisted of 28 days, same as the phase I. The entire treatment period is 6 cycles and tumor assessment is to be evaluated at the end of every 2 cycles.

This study is an open-label, controlled, multicenter, international, Phase III, randomized study of transplantation of NiCord® versus transplantation of one or two unmanipulated, unrelated cord blood units in patients with acute lymphoblastic leukemia or acute myeloid leukemia, myelodysplastic syndrome, chronic myeloid leukemia or lymphoma, all with required disease features rendering them eligible for allogeneic transplantation.

This phase III trial studies response-based chemotherapy in treating newly diagnosed acute myeloid leukemia or myelodysplastic syndrome in younger patients with Down syndrome. 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. Response-based chemotherapy separates patients into different risk groups and treats them according to how they respond to the first course of treatment (Induction I). Response-based treatment may be effective in treating acute myeloid leukemia or myelodysplastic syndrome in younger patients with Down syndrome while reducing the side effects.

This phase Ib trial studies the side effects and best dose of entinostat when given together with pembrolizumab in treating patients with myelodysplastic syndrome after deoxyribonucleic acid (DNA) methyltransferase inhibitor (DNMTi) therapy failure. Entinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving entinostat together with pembrolizumab may work better in treating patients with myelodysplastic syndrome after DNMTi therapy failure.

The purpose of this study is to determine whether the combination of pevonedistat and azacitidine improves event-free survival (EFS) when compared with single-agent azacitidine. (An event is defined as death or transformation to AML in participants with MDS or CMML, whichever occurs first, and is defined as death in participants with low-blast AML).

The purpose of this study is to determine the effectiveness of luspatercept (ACE-536) compared to epoetin alfa on red blood cell (RBC) transfusion independence (for at least 12 weeks) with a concurrent hemoglobin increase of at least 1.5 g/dL in participants with anemia due to revised international prognostic scoring system (IPSS-R) very low, low, or intermediate risk myelodysplastic syndromes (MDS) who require RBC transfusions and have never been exposed to erythropoiesis stimulating agent (ESA).
