Active clinical trials for "Myeloproliferative Disorders"

RATIONALE: Gathering information over time about patients' sense of being a burden on their caregiver, and caregivers' sense of burden on themselves, may help doctors learn more about the desire to die in patients with late-stage cancer. PURPOSE: This clinical trial is studying perceptions of burden in patients with late-stage cancer and their caregivers.

RATIONALE: Collecting and storing samples of blood from patients with cancer to test in the laboratory may help the study of cancer in the future. PURPOSE: This research study is collecting and storing blood samples from patients with cancer.

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 classic myeloproliferative neoplasias (MNP), including polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF) or secondary to PV or ET, are among the most frequent of malignant hemopathies, with overall prevalence estimated at around 10,000 patients followed in France. Due to the median age of patients around 65, the frequency of cardiovascular complications of these thrombogenic diseases and the impact of cytoreductive treatments on immune cells, these patients are considered to be at risk of developing forms severe of COVID-19. This study will assess the impact of MNPs on the risk of developing a severe form of COVID-19, identify new risk factors linked to the disease as well as the impact of treatments for MNPs according to their pharmacological class.

This is a prospective, multicenter observational study to collect clinically annotated biospecimens in order to assess the correlation between ex vivo data generated by the Notable assay platform and clinical outcome.

Analyze the results of conditioning with once-daily dose intravenous busulfan and fludarabine in patients undergoing HLA identical sibling Allogeneic HSCT for myeloid malignancies.

This is an observational prospective study aiming to clarify the prevalence of pulmonary hypertension in patients with Myeloproliferative Neoplasms and their prognosis. All patients attending our department with the above mentioned neoplasms will be offered inclusion in this study. All will have an echo performed and patients identified as being at risk of pulmonary hypertension will be offered complete investigation as specified by the European Cardiology Association. All patients will be followed up for a total of five years to identify prognosis.

Genzyme will evaluate/monitor the off label transplant use of plerixafor using data in the European Group for Blood and Marrow Transplantation (EBMT) registry. Off-label use of plerixafor will be collected for data entered over a 5 year time span (i.e., data entered into the registry between the date of European Union (EU) marketing authorization [31 July 2009] and 31 July 2014). The EBMT is a non-profit, scientific society representing more than 600 transplant centers mainly in Europe. The EBMT promotes all activity aiming to improve stem cell transplantation or cellular therapy, which includes registering all the activity relating to stem cell transplants. Data are entered, managed, and maintained in a central database with internet access; each EBMT center is represented in this database. The collection by the EBMT registry of reasons for the off-label transplant use of plerixafor shall provide information of a substantial number of patients who are representative of the patient population receiving plerixafor off-label.

The main goal of the study is to progress in our understanding of the molecular basis of myeloproliferative disorders of the bone marrow (polycythemia vera, essential thrombocythemia, primary myelofibrosis). The study will focus on the genes encoding factors implicated in the JAK-STAT pathway which has an essential role in these diseases
