Filter by:The purpose of this project is to find genes whose mutations cause Polycythemia Vera, Essential Thrombocythemia and Primary Myelofibrosis.
This study that will allow for the preservation and/or storage of a small portion one or more of the following tissues: - Peripheral blood - Bone marrow - Bone marrow biopsy - A phlebotomized unit of blood - Spleen cells - Toenail clippings This material will be used for the study of Myeloproliferative Disorders (MPD) by researchers. The goals of this research study are to understand the causes of MPDs, how to diagnose them more easily and how to treat them better. MPD is a disease affecting hematopoietic stem cells. Hematopoietic stem cells are cells that make blood cells. These stem cells grow in the center portion of the bones called bone marrow. Under some conditions, these cells are also found in blood. There are several diseases, which are classified as MPD. These include polycythemia vera (too many red blood cells), essential thrombocythemia (too many platelets), and idiopathic myelofibrosis (abnormal blood cells and fibers build up in the bone marrow). These syndromes carry a high risk of developing leukemia. It is important to continue to learn more about these blood cancers and to learn more about the effectiveness and potential side effects of various treatments.
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.
Researchers will use abnormal blood and/or bone marrow cells, or materials derived from these abnormal cells, like DNA, RNA, protein or plasma, in laboratory studies. Toenail clippings will provide normal material like DNA for comparison with the abnormal material derived from the blood and/or bone marrow. The results of these studies will be correlated with subjects' disease symptoms and response to their experimental treatment. The MPD-RC researchers are interested in studying molecules from the blood and bone marrow, the exact molecules changing over time with the investigators choosing only the most promising for investigation. The investigators are attempting to better understand the causes of MPD and to develop improved methods for the diagnosis and treatment of these diseases. These syndromes carry a high risk of developing leukemia. It is important to continue to learn more about these blood cancers and to learn more about the effectiveness and potential side effects of various treatments. It is believed that further basic knowledge about these cancer cells as well as the effects of treatment will lead to the improvement of current therapies and the development of entirely new treatments for these diseases. The MPD-RC is hoping to determine if a number of laboratory tests (biomarkers) will allow for the prediction of response in future patients to the treatment they would receive.
RATIONALE: Gathering information about patients with cancer and cancer-related conditions may help doctors learn more about a patient's needs and help doctors plan the best treatment. PURPOSE: This clinical trial is studying how well a whole-person-care guide works in identifying patient needs in patients with cancer or complications from cancer treatment.
This is an 18-week open-label, multicenter study to evaluate the efficacy and tolerability of CEP-701 (lestaurtinib) treatment in patients with Polycythemia Vera (PV) and patients with Essential Thrombocytosis (ET).
This is an observational safety study being conducted in Europe comparing patients taking Xagrid to patients taking other cytoreductive treatments. The plan is to enrol at least 750 subjects taking Xagrid with up to 3000 subjects taking other cytoreductive therapies. The study will collect follow up data for 5 years for each patient enrolled that will focus on collecting data related to pre-defined events (PDEs) and Suspected Serious Adverse Reactions (SSARs).
Infants who have low platelets and who require a platelet transfusion are included in this study. Platelet transfusions are routinely given to infants when their platelet count falls below a certain level. The study will look at the amount of platelets transfused. The purpose of the study is to evaluate the effect of platelet transfusions on the level of a protein (thrombopoietin) which is known to help control platelet production.
The purpose of this study is to evaluate the safety and tolerability of romiplostim (AMG 531) in the treatment of thrombocytopenia in pediatric subjects with chronic ITP. We will also evaluate the efficacy of romiplostim (AMG 531) and characterize the pharmacokinetics of romiplostim (AMG 531). It is anticipated that romiplostim (AMG 531), when given at an effective dose and schedule, will be well tolerated treatment for thrombocytopenia among pediatric subjects with chronic ITP.
To determine the safety, tolerability and effectiveness of ruxolitinib (INCB018424), administered orally to patients with Primary Myelofibrosis (PMF), Post Polycythemia Vera Myelofibrosis (PPV-MF) and Essential Thrombocythemia Myelofibrosis (PET-MF).
