Filter by:Multicenter, randomized, open-label, crossover PK study of ASTX727 versus IV decitabine. Adult subjects who are candidates to receive IV decitabine will be randomized 1:1 to receive the ASTX727 tablet Daily×5 in Cycle 1 followed by IV decitabine 20 mg/m^2 Daily×5 in Cycle 2, or the converse order. After completion of PK studies during the first 2 treatment cycles, subjects will continue to receive treatment with ASTX727 from Cycle 3 onward (in 28-day cycles) until disease progression, unacceptable toxicity, or the subject discontinues treatment or withdraws from the study.
This phase II trial studies how well topotecan hydrochloride and carboplatin with or without veliparib work in treating patients with myeloproliferative disorders that have spread to other places in the body and usually cannot be cured or controlled with treatment (advanced), and acute myeloid leukemia or chronic myelomonocytic leukemia. Drugs used in chemotherapy, such as topotecan hydrochloride and carboplatin, 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. Veliparib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving topotecan hydrochloride, carboplatin, and veliparib may work better in treating patients with myeloproliferative disorders and acute myeloid leukemia or chronic myelomonocytic leukemia compared to topotecan hydrochloride and carboplatin alone.
Chronic Myelomonocytic Leukemia (CMML) is the most frequent of myelodysplastic/myeloproliferative syndromes, as defined by the WHO classification of myeloid malignancies. The median age at diagnosis is around 70 years with a strong male predominance. CMML is a clonal disease of the bone marrow hematopoietic stem cell mainly characterized by persistent monocytosis (>1x109/L) and the presence of immature dysplastic granulocytes in the peripheral blood of CMML patients. Allogeneic stem cell transplantation (ASCT) remains the only curative option in CMML. However, CMML patients are rarely eligible for this kind of therapy, mainly due to their advanced age. The gold standard treatment of CMML thus remains hydroxyurea, which is usually initiated when the disease becomes proliferative, and demethylating agents, which could be efficient in the most aggressive forms of CMML. Nevertheless, the pathogenesis of CMML remains poorly understood and new therapies are urgently needed for patients in treatment failure. In recent years, a large numbers of gene mutations have been discovered in CMML, none of which are specific of this entity, as they can be encountered with different frequencies in other myeloid neoplasms. These mutated genes encode signaling molecules (NRAS, KRAS, CBL, JAK2, FLT3 and several members of the Notch pathway), epigenetic regulators (TET2, ASXL1, EZH2, IDH1, IDH2,.) and splicing factors (SF3B1, SRSF2, ZRSF2). Mutations in the transcription regulators RUNX1, NPM1 and TP53 have also been reported in CMML. However, the role of these mutations in leukemogenesis is still unclear. CMML is also characterized by defects in monocyte to macrophage differentiation. These defects in monocyte differentiation can be attributed to the presence of immature dysplastic granulocytes that secrete high levels of alpha-defensins HNP1-3 that antagonize the purinergic receptor P2RY6 in CMML patients. These CD14-/CD15+/CD24+ immature granulocytes that belong to the same clone than the leukemic monocytes seem to have immunosuppressive properties ressembling those of the myeloid-derived suppressor cells (MDCS) described in solid tumours. Whether these immature granulocytes contribute to autoimmune manifestations or immunoescape and progression of CMML is a conendrum and remains to be determined. In this context, the proposed project aims at identifying news insights into the pathophysiology of CMML through a better definition of the phenotype and function of monocytes and immature granulocytes that characterize this pathology.
The purpose of this study is to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and preliminary antitumor activity of AZD4573 in subjects with relapsed or refractory haematological malignancies.
This trial studies the side effects of recombinant EphB4-HSA fusion protein when given together with azacitidine or decitabine in treating patients with myelodysplastic syndrome, chronic myelomonocytic leukemia, or acute myeloid leukemia that has come back or has not responded to previous treatment with a hypomethylating agent. Recombinant EphB4-HSA fusion protein may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hypomethylating agents, such as azacitidine and decitabine, slow down genes that promote cell growth and can kill cells that are dividing rapidly. Giving recombinant EphB4-HSA fusion protein together with azacitidine or decitabine may work better in treating patients with myelodysplastic syndrome, chronic myelomonocytic leukemia, or acute myeloid leukemia.
This phase I/II trial studies the side effects and best dose of 211^astatine(At)-BC8-B10 before donor stem cell transplant in treating patients with high-risk acute myeloid leukemia, acute lymphoblastic leukemia, myelodysplastic syndrome, or mixed-phenotype acute leukemia. Radioactive substances, such as astatine-211, linked to monoclonal antibodies, such as BC8, can bind to cancer cells and give off radiation which may help kill cancer cells and have less of an effect on healthy cells before donor stem cell transplant.
This phase II trial studies how well an umbilical cord blood transplant with added sugar works with chemotherapy and radiation therapy in treating patients with leukemia or lymphoma. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The umbilical cord blood cells will be grown ("expanded") on a special layer of cells collected from the bone marrow of healthy volunteers in a laboratory. A type of sugar will also be added to the cells in the laboratory that may help the transplant to "take" faster.
The main purpose of this study is to determine the safe and recommended dose of APR-246 in combination with azacitidine as well as to see if this combination of therapy improves overall survival.
To characterize the safety and tolerability of 1) MBG453 as a single agent or in combination with PDR001 or 2) PDR001 and/or MBG453 in combination with decitabine or azacitidine in AML and intermediate or high- risk MDS patients, and to identify recommended doses for future studies.
This phase I/II trial studies the side effects of glutaminase inhibitor CB-839 in combination with azacitidine in treating patients with myelodysplastic syndrome that has spread to other places in the body. Glutaminase inhibitor CB-839 and azacitidine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
