Filter by:RO7490677 is an investigational drug that is being developed for possible use in the treatment of myelofibrosis (MF), a disease in which the bone marrow, which is the organ in the body that makes blood cells, is replaced by fibrosis, or excess scar tissue. The purpose of this study is to gather information on whether RO7490677 has an effect on the MF disease, whether it is safe in patients with MF, and how well it is tolerated.
The purpose of the study is to isolate and characterize stem cells of patients with Polycythemia Vera (PV) and Essential Thrombocythemia (ET) to find out why these cells are not working the way they should be and why they seem to be sensitive to regulatory factors in the blood, such as clotting.
This study is to determine the efficacy of momelotinib (MMB) versus ruxolitinib (RUX) in participants with primary myelofibrosis (PMF) or post-polycythemia vera or post-essential thrombocythemia myelofibrosis (post-PV/ET MF) who have not yet received treatment with a Janus kinase inhibitor (JAK inhibitor). Participants will be randomized to receive either MMB or ruxolitinib for 24 weeks during a double-blind treatment phase, after which they will be eligible to receive open-label MMB for up to an additional 216 weeks. After discontinuation of study medication, assessments will continue for 12 additional weeks, after which participants will be contacted for survival follow-up approximately every 6 months for up to 5 years from the date of enrollment or until study termination. For those participants planning to continue treatment with MMB following the end of the study, the Early Study Drug Discontinuation (ESDD), 30-day, 12-Week, and survival follow-up visits are not required.
There is a paucity of data on the aetiology of myeloproliferative neoplasms (MPNs). The investigators conducted a systematic review of the literature which identified several cohort and case-control studies that have investigated a wide range of potential medical, environmental and occupational risk factors. However, these studies have been limited by a wide variation in case definition and small sample sizes limiting the potential to detect modest risk differences between cases and controls. The research group propose an exploratory case-control study of 100 patients with classic MPNs and 200 controls to determine the optimal methods for roll out of this study to a multi-centred UK-based case-control study that will investigate the aetiology of MPN subtypes. The objectives of the study are to evaluate recruitment procedures, response rates and the development of a telephone administered questionnaire. The findings of this exploratory study will form the basis of a protocol for a large United Kingdom (UK)-wide case-control study of MPNs.
This study involves screening for portal vein thrombosis and portal hypertension in patients with Philadelphia negative myeloproliferative neoplasms (MPNs). These include polycythemia vera (PV), essential thrombocythemia (ET), and myelofibrosis. Portal vein thrombosis and portal hypertension are serious complications that are often seen in myeloproliferative patients. These complications are usually diagnosed when patients become symptomatic, and are often already at an advanced stage. They can further progress to cause non-reversible damage to the liver, also called cirrhosis of the liver. As a result of this, patients often accumulate fluid in the abdomen which is ascites; and can develop swelling of veins in the lining of the esophagus known as varices. If untreated, varices have the risk of rupturing resulting in life-threatening bleeding. When diagnosed at an advanced stage, the treatment is usually supportive therapy and there are no treatments available at present which can reverse these conditions. This study is looking at screening for these two conditions using Doppler ultrasound and upper gastrointestinal endoscopy.
This is a clinical study to evaluate the effect of CMPN (Chronic myeloproliferative neoplasm) to the bone. The hypothesis is that patients with CMPN have a higher fracture-rate compared to the background population. We expect to find a lower BMD using conventional DXA scan (dual energy x-ray absorptiometry), and a change in other parameters using HR-pQCT (high-resolution peripheral quantitative computerized tomography).Biochemical bone markers is measured to support the hypothesis.
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.
The purpose of this phase Ib/II clinical trial was to: a) evaluate the safety of the co-administration of LDE225 and INC424 in myelofibrosis patients and establish a maximum tolerated dose and/or Recommended Phase II dose of the combination and b) to assess the efficacy of the co-administration of LDE225 and INC424 on spleen volume reduction.
This phase II trial studies how well ruxolitinib phosphate and azacytidine work in treating patients with myelofibrosis or myelodysplastic syndrome/myeloproliferative neoplasm. Ruxolitinib phosphate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as azacytidine, 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 ruxolitinib phosphate and azacytidine may be an effective treatment for myelofibrosis or myelodysplastic syndrome/myeloproliferative neoplasm.
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.
