Active clinical trials for "Primary Myelofibrosis"

Patients who carried primary or secondary myelofibrosis from Philadelphia negative MPNs (PMF/SMF) and who are treated or are about to be treated with pegylated-interferon (mostly α2a) are eligible to this prospective study. Biological and clinical parameters will be collected from the beginning of the drug use until last news. A non-opposition consent form need to be signed before entering this study.

In patients with myelofibrosis, ruxolitinib is a current therapeutic option, which has demonstrated rapid and durable reduction in splenomegaly and improved disease-related symptoms. Anemia is another frequent issue in myelofibrosis. Consistent with its JAK2 signalling inhibition, ruxolitinib therapy has been shown to be detrimental on the hemoglobin level, increasing the depth of anemia or transfusion need. Despite potential antagonistic mechanisms of action on Janus Kinase 2, some responses on anemia have been reported with the addition of Erythropoiesis-stimulating Agent to ruxolitinib in a small subset of patients in the COMFORT II study. Ruxo-EPO is an observational study aimed to better assess the combination of Erythropoiesis-stimulating Agent and a Janus Kinase 2 inhibitor for therapeutic efficacy on anemia, Myelofibrosis evolution and for tolerance, in a larger cohort of patients treated for myelofibrosis in general practice.

The aim of the study is to determine the rate of HMR mutations in PMF and secondary MF (post PV/ET) subjects, and correlate the rate of mutations with clinical features as known prognostic scores.

The investigators would like to conduct a retrospective study in five centers in France in the goal to evaluate the survival of patients receiving allogeneic hematopoietic stem cell transplantation for myelofibrosis.

RATIONALE: Giving low doses of chemotherapy and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer or abnormal cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer or abnormal cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil before the transplant may stop this from happening. PURPOSE: This clinical trial is studying how well umbilical cord blood stem cell transplant works in treating patients with hematologic cancer or other disease.

The prospective multicenter observational cohort study will be offered consecutively to any patient with primary or secondary myelofibrosis or with Polycythemia Vera who has initiated therapy with ruxolitinib, prescribed as part of the normal course of care and completely independent of study participation. The main purpose is to assess adherence to ruxolitinib using the ARMS questionnaire. Each individual patient will be administered the questionnaire at the first convenient opportunity, regardless of when ruxolitinib is started, and again after 4, 8, 12, 24, and 48 weeks, in conjunction with drug procurement.

The purpose of this project is to find genes whose mutations cause Polycythemia Vera, Essential Thrombocythemia and Primary Myelofibrosis.

Myeloproliferative disorders occur in families, thus giving rise to the theory that it is a genetic disease that may be caused by an abnormal gene in the DNA that can be passed from one generation of family members to another. DNA can be gathered from family members through blood samples and the investigators will investigate (through DNA testing) to see if there are abnormal genes that may be responsible for causing the MPDs. Understanding which genes are responsible for causing MPDs can help develop ways to identify people who may be at risk for developing an MPD, allow for the development of better treatments, possibly a cure, or even prevent the development of MPDs.

The RUXOREL-MF observational study includes patients with primary and post-essential thrombocythemia/post-polycythemia vera myelofibrosis (MF) being treated with the oral JAK1-/JAK2-inhibitor ruxolitinib in a "real world" setting. Patients are treated according to current indications in Italy (i.e., primary and secondary MF patients with intermediate-1, intermediate-2, and high risk IPSS (International Prognostic Scoring System) scores and symptomatic splenomegaly and/or systemic symptoms). Patients are treated at facilities pertaining to the regional Hematology Network of Lombardy (Rete Ematologica Lombarda) in Italy. Efficacy data, data related to infectious and vascular events, data related to second primary malignancies, data regarding disease progression/transformation, and molecular information in relationship to ruxolitinib treatment will be collected and analyzed.

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.
