Filter by:Flonoltinib Maleate (FM) targets Janus kinase 2 (JAK2) and FMS-like tyrosine kinase 3 (FLT3). FM is a dual target inhibitor of JAK2/FLT3.FM has the activity of inhibiting JAK2 signaling pathway, and pharmacodynamics evaluation also confirmed that FM has a good therapeutic effect on the primary splenomegaly model of mice induced by JAK2V617 mutation.Therefore, FM has the potential to treat bone marrow proliferative tumors.The drug is intended to be used in patients with MPN, mainly including medium-risk or high-risk myelofibrosis (FM) (including primary myelofibrosis (PMF), post-polycythemia vera myelofibrosis (PostPV-MF) and post-primary thrombocythemia myelofibrosis (postET-MF)), Polycythemia vera (PV) and essential thrombocythemia (ET) were the primary causes of thrombocythemia and thrombocythemia. FM has high inhibitory activity against JAK family and FLT3 kinase, suggesting that FM may have a certain therapeutic effect on AML disease.The IC50 of JAK2 kinase inhibition by FM was as low as 0.8 nM, while the IC50 of JAK1, JAK3 and Tyk2 kinase inhibition was 690 nM, 557 nM and 65nM, respectively. The selectivity of JAK2 kinase inhibition by FM was 862.5, 696.3 and 81.3 times, respectively. Therefore, FM showed highly selective inhibition of JAK2 kinase.The IC50 for FLT3 kinase was 15 nM. FM has better inhibitory activity against JAK2 kinase than the listed Ruxolitinib and Fedratinib, and has better selectivity against JAK family.In order to determine whether FM has targets other than JAK2 and Flt3 kinases, we tested FM's inhibitory activity against 100 human kinases that are highly associated with tumors, including some common drug-resistant mutant kinases.The results showed that, except for CDK4/6, LCK and LN, FM had no obvious inhibitory activity against the screened kinases at 0.1 μm, and no other targets were found. In vitro experiments on the proliferation of JAK2-dependent and Flt3-related tumor cell lines with FM showed that the tumor cell lines had a significant inhibitory effect. The IC50 of half of the tumor cell lines was less than 0.5 μm, which was better than or equal to the similar drugs Ruxolitinib and Fedratinib. The effect of FM on tumor cells from MPN patients indicated that FM has the potential to treat MPN disease. In multiple animal models of bone marrow proliferative tumors with JAK2V617F mutations, FM showed superior efficacy and low toxicity (no obvious VISCAL toxicity) than existing drugs on the market, and the tumor inhibition effect of FM showed a good dose-dependent relationship. Objectives of Study Main Purpose: 1. Tolerance and safety of flonoltinib maleate Tablets tablets in patients with bone marrow proliferative tumors; 2. To observe the possible dose-limiting toxicity(DLT) of flonoltinib maleate tablets in patients with bone marrow proliferative tumors,To determine the maximum tolerated dose(MTD) of flonoltinib maleate tablets,To provide the basis for the recommended dose and design scheme of the later clinical trial. Secondary Purpose: 1. To evaluate the pharmacokinetic characteristics of single and repeated oral administration of flonoltinib maleate tablets in patients with bone marrow proliferative tumors; 2. To evaluate the primary efficacy of single and multiple oral flonoltinib maleate tablets in patients with bone marrow proliferative tumors.
This is a Phase 1 dose-escalation study of PRT1419, a myeloid cell leukemia-1 (MCL-1) inhibitor, in participants with selected relapsed/refractory myeloid or B-cell malignancies. The purpose of this study is to evaluate the safety and tolerability of PRT1419 monotherapy and in combination with either azacitidine or venetoclax, describe any dose limiting toxicities (DLTs), define the dosing schedule, and to determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D).
Reduced intensity conditioning (RIC) has emerged and been increasingly adopted as a modality to allow preparative conditioning pre transplant to be tolerated by older adults or those patients that are otherwise unfit for myeloablative conditioning. In this study, we aim to use RIC followed by matched related/unrelated donor, 7/8 matched related/unrelated donor, or haploidentical donor peripheral blood stem cell transplantation. Standard strategies to control the alloreactivity following HCT utilize immunosuppressive or cytotoxic medications. In this study, we explore donor graft engineering to enrich for immmunoregulatory populations to facilitate post transplantation immune reconstitution while minimizing graft versus host disease (GVHD) with post-transplant immunosuppressive agents.
The purpose of this research study is to look at how safe and useful a drug called azacitidine in combination with a drug called venetoclax, is in people with accelerated or blast phase BRC-ABL negative myeloproliferative neoplasms.
This study evaluates the risks and experience of blood clots and bleeding in patients with blood cancers. While it is standard of care to use medications to reduce the risk of blood clots in hospitalized individuals, some patients with blood cancers have low platelet counts that can increase the concern for bleeding complications associated with these medications. At this time, the optimal management strategies for blood clots are not well known for patients with blood cancers. This pilot study evaluates additional information that could help doctors know which patients are at highest risk for blood clots.
This phase I/II trial studies the side effects, best dose, and effect of tagraxofusp and decitabine in treating patients with chronic myelomonocytic leukemia. Tagraxofusp consists of human interleukin 3 (IL3) linked to a toxic agent called DT388. IL3 attaches to IL3 receptor positive cancer cells in a targeted way and delivers DT388 to kill them. Chemotherapy drugs, such as decitabine, 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. Giving tagraxofusp and decitabine may help to control the disease in patients with chronic myelomonocytic leukemia.
The primary objective of this study is to assess the safety and tolerability of administrating mutated-CALR peptide Vaccine to patients with MPN. The researchers plan to enroll 10 patients over a 12 month period. Maximum length of participation in 80 weeks. Patients will be asked to complete questionnaires, bone marrow biopsies, research lab collection, and standard of care lab draw. This research will be taking place only at The Mount Sinai Hospital, specifically at the Ruttenberg Treatment Center.
This phase II trial studies the effects of luspatercept with or without hydroxyurea in treating patients with myelodysplastic/myeloproliferative neoplasms with ring sideroblasts and thrombocytosis or unclassifiable with ring sideroblasts. Biological therapies, such as luspatercept, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Hydroxyurea may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving luspatercept with or without hydroxyurea may help doctors determine what doses of the combination is safe for patients to take and how the disease responds to the treatment.
Hematological malignancies gather several various pathologies included myeloproliferative disorders (as acute myeloid leukemia (AML) or chronic myeloid leukemia (CML)) and lymphoproliferative disorders (as chronic lymphoid leukemia (CLL), non-Hodgkin lymphoma (NHL) and multiple myeloma (MM)) . Over the last decade, the treatments have evolved significantly but the overall survival remains limited, especially for the AML and MM patients. There's an ongoing imperative to continue in-vitro and in-vivo studies to better evaluate the anti-cancer drugs sensitivity and therefore improving the response to treatments and open new fields of application. The healthy control group will be contributing to produce some pertinent and significant data for the results of the index cases group. The investigators aim to analyze 10 differents drugs, common use in chemotherapy or immunotherapy and evaluate by 2 ways the sensitivity: first, Flow cytometry (cells apoptosis by Annexine V and propidium iodide) on fresh samples and in a second time, monitoring of the blasts in the mouse's blood after injection.
A registry of UK patients diagnosed to have splanchnic vein thrombosis and myeloproliferative neoplasm, including isolated mutation of JAK2V617f. The purpose of the registry is to understand outcomes, treatment variations and data to inform and enable future clinical trial design and facilitate regulatory approval decision-making.
