Filter by: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.
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.
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.
To evaluate the safety and efficacy profile of different treatment regimens of Ruxolitinib (INCB018424) administered to two groups of patients; those with polycythemia vera (PV) and those with essential thrombocythemia (ET). Patients in each group were refractory to hydroxyurea or for whom hydroxyurea is contraindicated.
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.
