Filter by:The goal of this clinical research study is to learn if CC-4047 (now called pomalidomide) and prednisone can help to control MMM. The safety of this therapy will also be studied.
Clopidogrel (Plavix) and aspirin are two antithrombotic agents (blood thinners) commonly used in patients with previous thrombotic events (stroke or heart attack). Thrombosis is the formation of a blood clot in a blood vessel. Patients with polycythemia vera are routinely treated with aspirin which has been shown to be effective in reducing their thrombotic risk. However, in polycythemia vera patients with previous thrombosis, a further benefit might be obtained by using the combination of aspirin and clopidogrel which is routinely used in patients with recent acute myocardial ischemia (reduced blood supply to the heart muscle). The study will assess whether this combination therapy greatly increases the risk of bleeding versus aspirin alone, if clopidogrel reduces biological factors that might lead to a stroke or heart attack, and whether a high number of patients with polycythemia vera are resistant to clopidogrel. Approximately 200 subjects will be enrolled to the Myeloproliferative Disorders-Research Consortium (MPD-RC) study in Europe and the United States with participation expected to last for 7 months (6 months of receiving study medication plus a 30 day follow-up visit).
This study seeks to (i) determine a safe and tolerated dose of CYT387 (momelotinib) given to patients with PMF, post-PV or post-ET and, (ii) assess the effectiveness of orally-administered CYT387 as a treatment for PMF, post-PV or post-ET.
This was an open label, randomized study comparing the efficacy and safety of randomized 2:1 Ruxolitinib tablets versus best-available therapy, as selected by the investigator. The purpose was to compare the efficacy, safety and tolerability of Ruxolitinib (INC424/INCB018424) given twice daily to the best-available therapy, in subjects with primary myelofibrosis (PMF), post polycythemia vera myelofibrosis (PPV-MF) or post essential thrombocythemia myelofibrosis (PET-MF).
This study assessed the safety and efficacy of Panobinostat as a single agent in the treatment of Primary Myelofibrosis, Post-Polycythemia Vera and Post-Essential Thrombocythemia. There were two cohorts - participants with JAK2 mutation and participants without JAK2 mutation.
The primary objective of the study was to evaluate the efficacy of Givinostat in combination with hydroxyurea in patients with JAK2V617F-positive Polycythemia Vera (PV) non-responders to the maximum tolerated dose of hydroxyurea monotherapy. The secondary objectives of this study were: - To evaluate the safety and tolerability of Givinostat in combination with hydroxyurea in patients with JAK2V617Fpositive PV non-responders to the maximum tolerated dose of hydroxyurea monotherapy; - To explore the impact in terms of efficacy and tolerability of Givinostat 50 mg dose escalation in patients not achieving at least a partial response at the time when the primary endpoint was assessed (week 12); - To evaluate the molecular response (JAK2 mutated allele burden) by quantitative Real Time-Polymerase Chain Reaction (RT-PCR); - To evaluate the reduction of the fraction of JAK2V617F positive clonogenic progenitors.
This study is being conducted to test study drug AZD1480 to see how it may work to treat myeloproliferative diseases. The main purpose of this study is to determine the safety and tolerability of AZD1480. This is the first time the drug has been given to humans and is classed as a first time in man study. Its main purpose is to establish a safe dosage of the drug and provide additional information on any potential side effects this drug may cause. The study will also assess the blood levels and action of AZD1480 in the body over a period of time and will indicate whether the drug has a therapeutic effect on myeloproliferative diseases.
This phase I trial studies the side effects and the best dose of sunitinib malate in treating human immunodeficiency virus (HIV)-positive patients with cancer receiving antiretroviral therapy. Sunitinib malate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
The aim of the present study is to evaluate the efficacy and safety of MK-0683 in the treatment of PV and ET. This agent has most recently been shown to be a potent inhibitor of the autonomous proliferation of haematopoietic cells of PV and ET patients carrying the JAK2 V617F mutation. Accordingly, it may be anticipated that MK-0683 - by decreasing the JAK2 allele burden - may influence clonal myeloproliferation and in vivo granulocyte, platelet and endothelial activation , which are considered to be major determinants of morbidity and mortality ( thrombosis, bleeding, extramedullary haematopoiesis , myelofibrosis ) in these disorders. The effects of MK-0683 at the molecular level will be studied by global/ focused gene expression profiling, epigenome profiling and proteomics.
The study consists of two phases: The first portion of the study is a Phase 1 dose escalation study to determine the maximum tolerated dose and the dose limiting toxicities of SB1518 when given as a single agent orally once daily in subjects with Chronic Idiopathic Myelofibrosis (CIMF) regardless of their JAK2 mutational status. The second portion of the study is a Phase 2 study to define the efficacy and safety profile of single agent SB1518 at the recommended dose in subjects with CIMF.
