Filter by: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 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.
The purpose of this study is to find out if giving the study drug Ruxolitinib (INC424) prior to a combination of other chemotherapeutic drugs (Fludarabine and Busulfan) before infusing another person's hematopoietic stem cells (bone marrow transplantation) will be successful in people who have advanced primary myelofibrosis (PMF), post-polycythemia vera myelofibrosis (PPV-MF) or post-essential thrombocythemia myelofibrosis (PET-MF), collectively known as myelofibrosis (MF). MF is a disorder in which bone marrow tissue develops in abnormal sites because the bone marrow itself undergoes fibrosis or scarring. This study plans to evaluate whether adding the drug Ruxolitinib will further aid in reducing pre-transplant spleen size, improve physical performance levels and reduce adverse events (side effects) related to the transplant. Ruxolitinib is a drug that is approved by the FDA for the treatment of patients with advanced forms of myelofibrosis. Using Ruxolitinib prior to stem cell transplantation is experimental.
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.
The purpose of this study is to test a new drug called AUY922. AUY922 is not FDA-approved. AUY922 is a new kind of drug that attacks a protein called HSP90. HSP90 is found in both normal and cancer cells, but the investigators think it is more important in cancer cells. This study will see if AUY922 helps people with myelofibrosis, essential thrombocythemia and polycythemia vera. This study will also see if AUY922 is safe in people with myelofibrosis, essential thrombocythemia and polycythemia vera. It will find out what effects, good and/or bad, AUY922 has on the patient and the disease. The researchers hope that this study will help them to find better treatments for primary myelofibrosis, essential thrombocythemia and polycythemia vera.
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).
TGF-β is a cytokine that is found to be upregulated in the bone marrow of patients with myelofibrosis. This cytokine likely plays a dual role in promoting myelofibrosis and myeloproliferation, both of which are the bone marrow morphologic hallmark of MF. The investigators propose that inhibiting the TGF-β signaling pathway in MF will decrease the fibrogenic stimuli leading to myelofibrosis and concomitantly interrupt myeloproliferation. This is a novel approach to the treatment of patients with myelofibrosis.
The primary objective of this study is to determine the overall response rate to erlotinib in patients with polycythemia vera (PV). Response rate will be assessed by improvement in the complete blood count, ultrasound of the spleen, and JAK2 molecular status. It is purposed in this study to explore a possible molecular targeting of the driving mechanism of PV.
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 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.
