Filter by:This was a study of treatment with ruxolitinib in patients who presented with transfusion dependent or independent anemia. Starting dose was 10 mg BID. This dose was maintained for the first 12 weeks of the study and up-titrated thereafter unless the subject met criteria for dose hold or dose reduction
Prospective national multicenter randomized open label phase IIb RUXBETA trial.
The purpose of this prospective, longitudinal, noninterventional study is to describe clinical characteristics, evolution of disease burden, and treatment patterns in patients with select subcategories of essential thrombocythemia (ET) or myelofibrosis (MF).
Myeloproliferative neoplasms (MPN) such as Polycythemia Vera (PV) and, Essential Thrombocythaemia (ET) are rare clonal myeloid neoplasms associated with an increased risk of both venous and arterial thrombosis. Thrombotic complications are the main determinant of morbidity and in a less extend mortality. Routine haemostasis analysis (TP, aPTT) are usually normal and are useless to demonstrate a hypercoagulable state. However, previous evidence suggests that global coagulation tests such as thrombin generation or thromboelastometry are able to detect signs of procoagulant imbalance in MPN. Similarly, current data seems to demonstrate that fibrin clot properties (clot permeability, turbidimetry, clot lysis time) properties is altered suggesting an hypercoagulable state. Goals of PV and ET treatments are to control blood count to reduce the risk of thrombotic events. Moreover, new drugs such as Janus Kinase Inhibitors (JAKi) were recently licensed for PV and are under investigations on clinical trial for ET. It is currently unknown if treatments that were used for ET and PV, and especially JAKi are able to modify the hypercoagulable state that is observed in those diseases, and if there is difference between drugs. To evaluate impact of MPN treatment on prothrombotic haemostatic profile, we propose to evaluate global coagulation and fibrin clot properties in MPN, depending on the treatment.
All patients diagnosed or followed in Brest University Hospital for Philadelphia negative myeloproliferative neoplasms will be included in this observational study. Myeloproliferative neoplasms recorded included: polycythemia vera, essential Thrombocythemia and Primary Myelofibrosis. This is a not interventional study. Alive patients need to sign a non-opposition consent form. Patients will be followed until last news (death, change of reference centre...).
Patients treated with oral or sub-cutaneous drugs for polycythemia vera or essential thrombocythemia completed an unique paper questionnaire in order to describe their observance, the side effects and their own appreciation of the taken drug.
The aim of this study is to evaluate the endoplasmic reticulum stress markers as predictive for response to hydroxyurea in polycythemia vera (PV) and essential thrombocythemia (ET).
The main purpose of this investigational research study is to determine how safe and tolerable the study drug siltuximab is in patients with myelofibrosis (MF). This medication has been approved by the FDA for another condition (multicentric castleman's disease (MCD), but not for myelofibrosis (MF). In MCD, siltuximab resulted in improvement in symptoms and anemia. While MCD and MF are different diseases, they share some common features including a protein call interleukin-6 (IL-6) that may be important in causing symptoms of MCD and MF.
The mandate of this MPN registry is to collect clinical information, including molecular results, from consenting patients with a variety of MPNs at different time points during the course of their disease.
