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)
Colorectal cancer (CRC) is the third most common malignancy worldwide and is often metastatic at diagnosis. Despite progresses in surgical techniques and the introduction of novel chemotherapy regimens, many patients still suffer from a poor prognosis. It is therefore of utmost importance to identify prognostic markers that may improve selection of patients. In recent years several studies demonstrated that preoperative blood tests as platelet count or neuthophil-to-lymphocyte ratio could be prognostic factors in CRC as well as other malignancies. The aim of this study was to evaluate the role of preoperative platelet count (PC) in patients with synchronous colorectal liver metastases.
This study evaluates KRT-232, a novel oral small molecule inhibitor of MDM2, for the treatment of patients with myelofibrosis (MF) who no longer benefit from treatment with a JAK inhibitor. Inhibition of MDM2 is a novel mechanism of action in MF. This study will be conducted in 2 phases. Phase 2 will determine the KRT-232 recommended dose and dosing schedule; Phase 3 will test KRT-232 vs Best Available Therapy (BAT). Patients in the Phase 3 part of the study will be randomized 2:1 to receive either KRT-232 (Arm 1) or BAT (Arm 2). The BAT administered will be determined by the treating physician, with the option to "cross-over" to KRT-232 treatment after 6 months of BAT or if the disease worsens at any time.
This is a phase II, open label, prospective, single-arm study evaluating the efficacy and safety of selinexor in patients with PMF or secondary MF (PPV-MF or PET-MF) who are refractory or intolerant to ruxolitinib and/or any other experimental JAK1/2 inhibitors.
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.
Reactive or secondary thrombocytosis is defined as abnormally high platelet count (≥4,50,000 platelets per micro-liter) in the absence of chronic myeloproliferative disease. In critically ill patients reactive thrombocytosis is not uncommon during recovery phase and an association has been seen with poor outcome and increased risk of subsequent VTE. However, not all patients with infection respond with thrombocytosis. No study has enumerated the risk factors or predictors of reactive thrombocytosis in critically ill septic patients.
The primary objective of this study is to provide extended access and assess long-term safety of momelotinib (MMB) in participants with primary myelofibrosis (PMF) or post-polycythemia vera or post-essential thrombocythemia myelofibrosis (Post-PV/ET MF) enrolled in studies GS-US-352-0101 (NCT01969838), GS-US-352-1214 (NCT02101268), GS-US-352-1154 (NCT02124746), SRA-MMB-301 who are currently receiving treatment with MMB (available as 50mg,100 mg, 150 mg and 200 mg tablets) and have not experienced progression of disease. The secondary objective is to assess overall survival (OS) and leukemia free survival (LFS) in all subjects.
