Active clinical trials for "Polycythemia Vera"

This phase I trial studies the side effects and best dose of arsenic trioxide with or without ascorbic acid in treating patients with myelofibrosis. Drugs used in chemotherapy, such as arsenic trioxide, 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. Giving arsenic acid together with ascorbic acid may kill more cancer cells.

This phase II trial studies how well nivolumab works in treating patients with primary myelofibrosis, post-essential thrombocythemia myelofibrosis, or post-polycythemia vera myelofibrosis. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

This open-label study is to determine the safety and efficacy of momelotinib in participants with either polycythemia vera (PV) or essential thrombocythemia (ET) who have not yet received treatment with a Janus kinase (JAK) inhibitor.

A lead-in cohort of ~20 patients with primary or secondary myelofibrosis previously treated with 1 or more Janus kinase inhibitors enrolled to single-agent glasdegib to evaluate safety and tolerability. Following the lead-in, a phase 2, double blind, 2-arm study, randomized 2:1 to oral single-agent glasdegib versus placebo in 201 patients resistant or intolerant to ruxolitinib.

The purpose of this study is to evaluate the safety and tolerability of XL019 in adults with myelofibrosis. XL019 is a selective inhibitor of the cytoplasmic tyrosine kinase JAK2. JAK2 is activated by cytokine and growth factor receptors and phosphorylates members of the STAT family of inducible transcription factors. Activation of the JAK/STAT pathway promotes cell growth and survival, and is a common feature of human tumors. JAK2 is activated by mutation in the majority of patients with myelofibrosis, polycythemia vera and essential thrombocytosis and appears to drive the inappropriate growth of blood cells in these conditions.

The purpose of this study is to evaluate the safety and tolerability of the JAK2 inhibitor XL019 administered orally in adults with Polycythemia Vera.

Phase 3, randomized, controlled study to evaluate the safety and efficacy of oral pacritinib compared to Best Available Therapy (BAT) in patients with primary or secondary myelofibrosis.

CYTO-PV is a phase III Prospective, Randomized, Open-label, with Blinded Endpoint evaluation (PROBE), multi-center, clinical trial in patients with diagnosis of Polycythemia vera (PV) treated at the best of recommended therapies (e.g.adequate control of standard cardiovascular risk factors). Irrespective of randomized interventions, all patients will be administered low-dose aspirin (when not contraindicated), i.e.the standard antithrombotic treatment in PV patients. The purpose of this study to demonstrate that a more intensive cytoreductive therapy, plus low-dose aspirin when not contraindicated, with phlebotomy and/or hydroxyurea (HU), aimed at maintaining hematocrit (HCT) < 45% is more effective than a less intensive cytoreduction (either with phlebotomy or HU plus low-dose aspirin when not contraindicated) maintaining HCT in the range of 45-50% in the reduction of CV deaths plus thrombotic events (stroke, acute coronary syndrome [ACS], transient ischemic attack [TIA], pulmonary embolism [PE], splanchnic thrombosis, deep vein thrombosis [DVT], and any other clinically relevant thrombotic event), in patients with Polycythemia Vera treated at the best of recommended therapies (e.g. adequate control of standard cardiovascular risk factors).

Phase 3, randomized, controlled study to evaluate the safety and efficacy of oral pacritinib compared to Best Available Therapy (BAT) in patients with thrombocytopenia and primary or secondary myelofibrosis.

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.
