Filter by:The aim of the study is to examine (a) whether patients with JAK2 V617F positive ET in comparison to age-and sex-matched, apparently healthy control subjects show more advanced progression of arterial stiffness, pulse-wave velocity and coronary calcium score in a 4 year observation period, and (b) whether the burden of JAK2 V617F mutation correlates with the measured vascular parameters. All subjects will be examined twice. The first visit already took place between the years 2014 - 2015 and the second visit will take place between 2018-2019. All participants will have signed their informed consent before entering the study. Each visit will consist of completing a structured questionnaire (on personal and family medical history, risk factors for CVD and medication), physical examination, donating a blood sample for laboratory tests and undergoing carotid ultrasound and coronary calcium measurement oft the extent of coronary artery calcification. At the first and the second examination the JAK2 V617F allele burden, i.e. the percentage of mutated alleles, will be determined from genomic DNA in peripheral blood.
This is Single-Arm, Open-Label Efficacy and Safety Trial of Fedratinib in Subjects with DIPSS (Dynamic International Prognostic Scoring System)-Intermediate or High- Risk Primary Myelofibrosis (PMF), Post-Polycythemia Vera Myelofibrosis (post-PV MF), or Post-Essential Thrombocythemia Myelofibrosis (post-ET MF) and Previously Treated with Ruxolitinib. The primary objective of the study is to evaluate the percentage of subjects with at least a 35% reduction in spleen size and one of the secondary objectives is to evaluate the safety of fedratinib.
The incidence of secondary cancer (SC) in patients with myeloproliferative neoplasms (MPN) is high and comparable to that of thrombosis. However, the identification of patient subgroups that might be at increased susceptibility of developing SC has not been systematically addressed. This international case-control study (MPN-K) is aimed to elucidate the prognostic role of JAK2V617F mutation in predicting the occurrence of SC in patients with classical MPN, polycythemia vera (PV), essential thrombocythemia (ET) and myelofibrosis (MF)
The objective of this survey is to collect data to evaluate the safety and efficacy of anagrelide hydrochloride in the post-marketing phase in participants diagnosed with Essential Thrombocythemia (ET).
A phase-I-first in man study in patients with calreticulin(CALR)-mutant MPN by vaccinating with exon 9 mutated peptide with the adjuvant Montanide ISA-51 to monitor safety and toxicity and the immunological response to vaccination.
This study is to evaluate the efficacy and safety according to incremental dosing for 8 weeks and duration of administration for 1 year in patients with high-risk essential thrombocythemia.
There is no prospective study published on the Essential Thrombocythemia and the correlation between this specific disease, its complications and the biological variations observed. The aim of this study is to demonstrate a correlation between biological tests of haemostasis, as Multiplate analyser and thromboelastometry (ROTEM) and the occurrence of clinical complications, thrombosis and/or haemorrhage, in order to determine if this biological tests could be biological prognostic factors
This is a Phase 1/2 open-label study to evaluate the safety, tolerability, steady-state pharmacokinetic (PK) and pharmacodynamics (PD) of a lysine-specific demethylase 1 (LSD1) inhibitor, bomedemstat (IMG-7289/MK-3543), administered orally once daily in participants with myelofibrosis. The primary hypothesis is that bomedemstat is a safe and tolerable orally available agent when administered to participants with myelofibrosis including primary myelofibrosis (PMF), post-polycythaemia vera-myelofibrosis (PPVMF), and post-essential thrombocythaemia-myelofibrosis (PET-MF) (collectively referred to as 'MF'); inhibition of LSD1 by bomedemstat will reduce spleen size in those with splenomegaly, improve haematopoiesis and reduce constitutional symptoms associated with these disorders.
The purpose of this study is to test the effectiveness of a drug called pembrolizumab in patients with Myeloproliferative Neoplasm (MPN); chronic phase (MF-CP), accelerated phase (MPN-AP), or blast phase (MF-BP). Myelofibrosis neoplasm (MPN) is a group of diseases of the bone marrow in which excessive cells are produced. Pembrolizumab also known as Keytruda is a drug that has recently been approved in the United Stated by the Food and Drug Administration (FDA) for the treatment of patients with unresectable or metastatic melanoma and disease progression. Pembrolizumab is experimental in the treatment of MPN. The researchers want to find out what effects, good and /or bad it has on participants and the disease. Participants qualify to take part in this research study if have been diagnosed with a MPN blood disorder called myelofibrosis (MF). Accelerated (10-19% blasts in the blood or bone marrow) and blast phase (>20% blasts in the blood or bone marrow) MPN has been a difficult disease to treat. The term "blasts" refers to immature cells found in the bone marrow. They are not fully developed, and therefore, do not yet carry out any particular function within the body. Funds for conducting this research are provided by Merck and Company, the manufacturer of the study drug pembrolizumab.
This was a study of treatment with ruxolitinib in patients who presented with transfusion dependent or independent anemia. Starting dose was 10 mg BID. This dose was maintained for the first 12 weeks of the study and up-titrated thereafter unless the subject met criteria for dose hold or dose reduction
