Active clinical trials for "Hematologic Diseases"

Background: Researchers seek ways to study people s medical problems in order to teach and further general knowledge. The ability to assess and treat people with a wide range of diseases is critical to training people to be good doctors. It is also needed to keep medical staff up to date. In this study, researchers want to study the course of some illnesses to learn more about them. To do this, they will collect and review people s medical records. In some cases, they may also provide treatment. Objective: To collect data that may be used to help researchers create ideas for future research. Eligibility: People age 2 and older who have or are suspected to have a medical condition for which they have been referred to NIH s National Heart, Lung, and Blood Institute, as well as stem cell donors Design: Participants may be screened with a review of the following: Medical records Scans and images Other existing samples and reports. Participants medical data will be collected from the standard care they receive. This includes their routine blood and urine tests, X-rays and scans, and other tests to diagnose or follow their medical condition. Data will also be collected from the treatments they may receive. For stem cell donors, data from apheresis procedures will be collected. Demographic data will also be collected. All of the data will be kept in the medical records or on secure network drives. Some participants may need to be treated for their medical condition. If so, they will sign a separate consent form for that treatment. Participation lasts up to 2 years.

This is a treatment guideline for HLA-Haploidentical hematopoietic stem cell transplant (HSCT) using a reduced intensity conditioning (RIC) regimen. This regimen, consisting of fludarabine, cyclophosphamide and low dose total body irradiation (TBI), is designed for the treatment of patients with advanced and/or high risk diseases.

This study allows the evaluation of subjects in order to determine their ability to safely participate in other active research studies. After subjects complete the screening process, they will be offered the opportunity to participate in an active research study, or if no appropriate studies are available information and recommendations will be provided for other treatment options....

The purpose of this study is to obtain tissue samples for ongoing studies regarding transplant outcomes and complications.

Human cytomegalovirus (CMV) infection is a major cause of morbidity and mortality for recipients of allogeneic hematopoietic stem cell transplantation(HSCT). we propose to study the immunologic and virologic effects of donor derived CMV specific cytotoxic T lymphocyte (CMV-CTL) given to transplant recipients CMV antigen peptides will be used to induce the CMV antigen specific T lymphocytes derived from donor peripheral blood mononuclear cells for a period of 18~21 days.The patients will receive CMV-CTL cells when they are sero-positive for CMV-DNA 30 days after transplant. The CMV-DNA level will be monitored weekly after transfusion.

Part 1 will be conducted as an open-label, non-randomized, non-placebo-controlled dose escalation study using pre-specified doses. Subjects with the following advanced hematological disorders and no available therapies, and who satisfy all inclusion/exclusion criteria will be enrolled. The purpose is to identify the recommended dose of oral ORH-2014 in subjects with advanced hematological disorders. Part 2 will be an expansion phase conducted as a single-arm, open-label study to further evaluate the safety and tolerability of ORH-2014 at the maximum tolerated dose (MTD) or recommended dose determined from Part 1 in the fasted state. Subjects with the same disease types as in Part 1 will be enrolled. All subjects will receive oral ORH-2014, in the fasted state, at the recommended dose for an initial period of up to 12 weeks. The purpose is to evaluate the safety and tolerability of oral ORH-2014 in a population of subjects with advanced hematological disorders when administered at the recommended dose.

The XIENCE 28 USA Study is prospective, single arm, multi-center, open label, non-randomized trial to evaluate safety of 1-month (as short as 28 days) dual antiplatelet therapy (DAPT) in subjects at high risk of bleeding (HBR) undergoing percutaneous coronary intervention (PCI) with the approved XIENCE family (XIENCE Xpedition Everolimus Eluting Coronary Stent System [EECSS], XIENCE Alpine EECSS and XIENCE Sierra EECSS) of coronary drug-eluting stents.

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.

Background: - Hypereosinophilic syndrome (HES) is a disorder in which the body has too many eosinophils (a type of white blood cell). Too many eosinophils in HES can cause damage to the heart, nerves, or skin. Certain drugs can help lower eosinophil counts to prevent tissue damage. Corticosteroids, such as prednisone, are used for initial therapy in this disorder. Although most people respond to prednisone, some people develop side effects from it, or do not respond very well to treatment. Better ways of determining the dose to give could help to decide on the best therapy for HES. Objectives: To determine whether a single-dose of prednisone can be used to predict which people with hypereosinophilia respond to treatment. To study lack of response to steroid treatment in people with HES. Eligibility: Inclusion criteria: Individuals with hypereosinophilic syndrome with high eosinophil counts. Individuals who are willing to have blood drawn before and after getting steroids. Exclusion criteria: Individuals who are on more than 10mg of prednisone (or similar drug) Individuals with hypereosinophilic syndrome who are on other medications that could interfere with the study Women who are pregnant or breast-feeding Individuals who have a known gene mutation associated with chronic eosinophilic leukemia Children less than 18 years old who weigh less than 48kg or 106lb Design: Participants will have a screening visit with a physical exam and medical history. Blood and urine samples will be collected. Participants will have a single dose of the steroid prednisone by mouth in the morning. Blood samples will be collected 2, 4, 24 hours after this dose. On the day after the steroid dose, participants will provide another blood sample in the morning. Participants will start to take prednisone daily when they return home. Blood samples will be collected weekly at the participant s doctor s office. The dose of prednisone will be lowered depending on the weekly eosinophil count. We will try to get each person on the lowest dose of prednisone possible that will control the disorder. Participants who do not respond or have severe side effects will be taken off prednisone. Other treatments will be considered for people who do not respond to steroids. The goal is to evaluate the response to prednisone. Our research will try to figure out why some people do not respond to steroids. Most people will complete the study within 6 to 16 weeks, depending on their response to prednisone.

The purpose of this study is to evaluate the use of CPAP in the prevention of acute respiratory failure in neutropenic ( or hematologic malignancy ) patients .CPAP applied preventively in hematological patients with high risk of ARF may reduce:need for intubations and mechanical ventilation, incidence of pneumonia and sepsis,mortality,length of ICU and hospital stay
