Filter by:The MPL gene is implicated in two groups of hematological pathologies: congenital amegakaryocytic thrombocytopenia (CAMT) and Phi negative myeloproliferative neoplasia (MPN). Fifty germline mutations have been identified in CAMT, yet only a dozen activating mutations have been described in MPN. Most are somatic, distributed mainly in the transmembrane (TM) and juxtamembrane (JM) domains. However, a few rare germline mutations located in the extracellular domain (ECD) have also been reported: K39N, R102P and P106L. Next generation sequencing technology has been used to study the complete MPL gene, identifying numerous variants, most of unknown significance. The study investigators have a series comprising 41 variants of unknown significance, whose allelic frequencies suggest a germline origin for 80% of them. Their distribution within the MPL gene is similar to that of inactivating mutations, except that they were discovered in the context of suspected myeloproliferative disease. Characterizing the activity of these variants would confirm the diagnosis of MPN, opening the door to specific treatment (cytoreductive, JAK2 inhibitor or interferon). It also has an important prognostic value, particularly in the case of MPN, for which life expectancy varies from 5 to 7 years, with terminal progression to acute myeloid leukemia (AML in 15 to 20% of cases) or bone marrow failure. Using a battery of functional assays, this study aims to characterize these variants.
This is a prospective phase I dose-escalation study, with the primary objective to access the MTD and find the RP2D of talazoparib, given in combination with standard of care dosing of pacritinib.
BCR:ABL1 negative myeloproliferative neoplasms (MPN) include three entities: polycythemia vera, essential thrombocythemia and primitive myelofibrosis. Myelofibrosis is a life-threatening complication in MPN with several therapeutic options including hematopoietic stem cell transplantation (HSCT) which remains the only curative treatment. Bone marrow biopsy with histological analysis allows myelofibrosis identification and staging. However, it is an invasive procedure that remains painful and provides potential haemorrhagic complications. Development of non-invasive biomarkers for myelofibrosis staging could help to better stratify this disease, better define patients' prognosis and lead to optimal cares. The main aim of this work is to develop a non-invasive blood score including several biomarkers for myelofibrosis staging in MPN using bone marrow biopsy as a gold standard.
Multicenter prevalence study of the PNH clone (paroxysmal hemoglobinuria nocturnal) in SMP Ph-. This multicenter, prospective study aims to evaluate the presence of an PNH clone in patients with a confirmed diagnosis of myeloproliferative neoplasia Phcon or without mutations in the 3 main genes involved in this disease (JAK2, MPL, and Cal-R),but showing signs of ongoing hemolysis or particular clinical conditions. To this end, a multicolor flow cytometric test will be used to evaluate the presence of deficient GPI molecules in granulocytic, monocytic and other cells erythrocyte (flow cytometric test, based on the use of the FLAER reagent in peripheral blood samples). The study will be conducted at clinical hematology centers in the wider area of the Romagna and at other Italian hematology clinical centers, where and analyzed the peripheral blood samples and clinical data to be included in the study. The participating centers will carry out the flow cytometric diagnostic test at i own reference laboratories, while the biological material for subsequent studies genetic-molecular type (next generation sequencing) will be analyzed centrally at the Biosciences laboratory of the IRST IRCCS only for cases testing positive for the presence of the PNH clone. Clinical information will be collected for each patient enrolled in the study necessary for the classification of the case and all the laboratory data necessary for achievement of the objectives of the study. The main objective of the study is to evaluate the prevalence of PNH clones in patients with a confirmed diagnosis of myeloproliferative neoplasm Ph- with or without mutations affecting the 3 main genes involved in this disease (JAK2, MPL, e Cal-R), but showing signs of ongoing hemolysis or particular clinical conditions. Secondary objectives of the study are: - correlate the characteristics of the PNH clone with the clinical characteristics and laboratory of myeloproliferative neoplasms Ph- (the presence of phenomena thrombotics, the disease state, the DIPSS prognostic score index, and the state mutational). · characterize the genomic architecture of the cases using NGS technology positive results
The purpose of this study is to characterize safety and to determine the Recommended Phase 2 Dose (RP2D[s]) and optimal dosing schedule(s) of JNJ-88549968, in part 1 (Dose Escalation); to characterize the safety of JNJ- 88549968 at RP2D(s), in part 2 (Cohort Expansion).
The purpose of this research study is to test the safety and efficacy of cytokine induced memory-like (CIML) natural killer (NK) cells expanded with Interleukin-2 (IL-2) at preventing relapse in acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), or MDS and myeloproliferative neoplasm (MPN) overlap syndrome after a standard-of-care stem cell transplant. Names of the study therapies involved in this study are: - CIML NK cells intravenous infusion (cellular therapy) - Subcutaneous Interleukin-2 (recombinant, human glycoprotein)
The use of venetoclax-based therapies for pediatric patients with relapsed or refractory malignancies is increasingly common outside of the clinical trial setting. For patients who cannot swallow tablets, it is common to crush the tablets and dissolve them in liquid to create a solution. However, no PK data exists in adults or children using crushed tablets dissolved in liquid in this manner, and as a result, the venetoclax exposure with this solution is unknown. Primary Objectives • To determine the pharmacokinetics of venetoclax when commercially available tablets are crushed and dissolved into a solution Secondary Objectives - To determine the pharmacokinetics of venetoclax solution in patients receiving concomitant strong and moderate CYP3A inhibitors - To determine potential pharmacokinetic differences based on route of venetoclax solution administration (ie. PO vs NG tube vs G-tube) - To determine the concentration of venetoclax in cerebral spinal fluid when administered as an oral solution
This phase II trial evaluates how a curcumin supplement (C3 complex/Bioperine) changes the inflammatory response and symptomatology in patients with clonal cytopenia of undetermined significance (CCUS), low risk myelodysplastic syndrome (LR-MDS), and myeloproliferative neoplasms (MPN). Chronic inflammation drives disease development and contributes to symptoms experienced by patients with CCUS, LR-MDS, and MPN. Curcumin has been shown to have anti-inflammatory and anti-cancer properties and has been studied in various chronic illnesses and hematologic diseases.
This phase II clinical trial tests how well the cytomegalovirus-modified vaccinica Ankara (CMV-MVA) Triplex vaccine given to human leukocyte antigens (HLA) matched related stem cell donors works to prevent cytomegalovirus (CMV) infection in patients undergoing hematopoietic stem cell transplant. The CMV-MVA Triplex vaccine works by causing an immune response in the donors body to the CMV virus, creating immunity to it. The donor then passes that immunity on to the patient upon receiving the stem cell transplant. Giving the CMV-MVA triplex vaccine to donors may help prevent CMV infection of patients undergoing stem cell transplantation.
This phase I trial finds the best dose of PVEK when given together with fludarabine, cytarabine, granulocyte colony-stimulating factor (G-CSF), and idarubicin, (FLAG-Ida) regimen and studies the effectiveness of this combination therapy in treating patients with newly diagnosed adverse risk acute myeloid leukemia (AML) and other high-grade myeloid neoplasms. PVEK is a monoclonal antibody linked to a chemotherapy drug. PVEK is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD123 receptors, and delivers the chemotherapy drug to kill them. Chemotherapy drugs, such as idarubicin, fludarabine, high-dose cytarabine 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. G-CSF helps the bone marrow make more white blood cells in patients with low white blood cell count due to cancer treatment. Giving PVEK with the FLAG-Ida regimen may be a safe and effective treatment for patients with acute myeloid leukemia and other high-grade myeloid neoplasms.
