The investigators will assess the use of a smart phone app to monitor patient reported outcomes and record biometric data in patients with myeloproliferative neoplasms.
This is a randomized, open-label, multicenter, two-arm study to assess the efficacy and safety of ropeginterferon alfa-2b for patients with low-risk PV. Approximately 110 patients with low-risk PV will be enrolled. The whole study period is 108 weeks, including a main treatment phase (56 weeks), an extension treatment phase (48 weeks), and a safety follow-up phase (four weeks).
The goal of Part 1 of this clinical research study is to find the highest tolerable dose of ASTX029 that can be given in combination with ASTX727 to participants who have RAS-mutant MDS or MDS/MPN. The goal of Part 2 of this clinical research study is to learn if the dose of ASTX029 found in Part 1 can help to control the disease when used in combination with ASTX727.
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.
Myeloproliferative neoplasms (MPN) are chronic myeloid malignancies characterized by a risk of evolution to acute myeloid leukemia (AML). This unpredictable complication is associated with a grim outcome with median overall survival ranging between 2 to 10 months. To date, even allogeneic transplantation fails to significantly improve the prognosis. Biological and molecular mechanisms driving leukemic transformation are complex, ill-defined, and heterogeneous between patients. The investigator hypothesize that deciphering the molecular heterogeneity of post-MPN AML may lead identifying efficient drugs targeting of the most relevant leukemogenic pathways. Our main objective is to identify new targeted therapeutic approaches in post-MPN AML through in-depth characterization of the dysregulated pathways. The investigator will first characterize in an already annotated cohort of 120 post-MPN AML homogeneous patients subgroups using comprehensive multiomic analyses. Dysregulated pathways will be identified in each subgroup using the omics data and single-cell RNA-sequencing will be performed in a subset of patients in each subgroup. A customised drug-panel will be derived from the dysregulated pathway for an ex vivo drug screening, which will use a flow-cytometry read-out enabling to identity drug effect on cells survival, differentiation, and stemness. The 3 most promising drugs will be validated in a preclinical in vivo model of patient's derived xenograft (PDX) and their impact on clonal architecture will be studied in primary cell cultures using single-cell DNA-sequencing. Overall, this proposal may provide a better understanding of MPN leukemic transformation mechanisms and provide a path for personalized therapies. Our findings may therefore pave the way to drugs development in post-MPN AML that would provide a rationale for implementation of early clinical trials in these dreadful diseases.
The purpose of this study is to learn about the impact that the services and programs provided by the Leukemia and Lymphoma Society have among patients with blood cancer, such as access to care, quality of life, and financial burden.
First-line treatment for patients with polycythemia vera, essential thrombocythemia, and pre-myelofibrosis is based on hydroxyurea or pegylated interferon. The objective of treatment is to prevent thrombotic complications and leukemic transformation. Despite overall good response rates, some patients do not respond to treatment and others lose their response over time. Both situations are associated with worse survival and there are to date no clear predictive factors for response although the existence of additional mutations seems unfavorable. In this exploratory study, we hypothesize that biological factors at diagnosis are associated with hematological response at 12 months. We will more specifically study the association between mutational profile, assessed by next-generation sequencing, and cytokine profile with hematological response. This study will help in identifying patients who will not respond to hydroxyurea or pegylated interferon and give the opportunity to try other treatments upfront, in the perspective of precision medicine. On the basic science side, this study will help in understanding the molecular and immunological factors involved in resistance to treatment.
Myeloproliferative neoplasms (MPNs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, may lead to gastroesophageal varices. The quality of life, morbidity, and mortality of MPN patients mainly depend on disease-related symptoms, thromboembolic and hemorrhagic complications. Previous studies have shown that JAK2 V617F has a prominent role in vascular risk and MPN-associated gastroesophageal varices. The aim of this study is to evaluate the efficacy of anticoagulation in patients with JAK2 mutation and gastroesophageal varices.

The quality of life, morbidity, and mortality of MPN patients mainly depend on disease-related symptoms, thromboembolic and hemorrhagic complications. Previous studies have shown that JAK2 V617F has a prominent role in vascular risk and MPN-associated gastroesophageal varices. Portal vein thrombosis and portal cavernoma frequently occur in the MPN population and the management of gastroesophageal varices in these patients are sometimes technically difficult. The aim of this study is to investigate the the characteristics of patients with gastroesophageal varices and portal caver cavernoma with or without JAK2 mutation.
