Filter by:Background: People who have a blood stem cell transplant can sometimes develop cytopenia. This means that their levels of one or more types of blood cell, such as the red cells or platelets, are lower than they should be. This can occur because a person s immune system might attack these cells after a stem cell transplant. Cytopenia can lead to anemia, severe bleeding, infections, and other problems. Treatments are needed to help keep blood cell levels stable after blood stem cell transplant. Objective: To test a study drug (fostamatinib) in people who have cytopenia after a blood stem cell transplant. Eligibility: People aged 18 to 75 years who have cytopenia after a blood stem cell transplant. Design: Participants will be screened. They will have a physical exam. They will have blood, urine, and stool tests. Fostamatinib is an oral tablet taken by mouth. Participants will take the pills 2 times a day for 12 weeks. Participants will have a medical assessment every 2 weeks; their vital signs will be checked, and they will have blood and stool tests. Participants must come to the NIH clinic for these visits in weeks 4 and 12. Other visits may be done by telephone or telehealth; the blood and stool tests can be sent to the researchers from a local lab. After 4 weeks, some participants may begin taking a higher dose of the drug. Participants will return for a final medical assessment 2 weeks after they finish taking the drug. Participants who complete this study and show evidence that fostamatinib has increased their blood cell counts may enroll in an extension study to continue taking fostamatinib.
Background: Chronic Graft Versus Host Disease (cGVHD) can occur after a person has had a stem cell or bone marrow transplant. In cGVHD, the donor cells attack the recipient s body. Researchers want to see if a drug called ibruntinib can block one of the proteins that lead to the immune reaction that causes cGVHD. Objective: To see if ibrutinib as a first-line treatment can help people with newly diagnosed cGVHD. Eligibility: People age 18 and older with newly diagnosed moderate or severe cGVHD Design: Participants will be screened with medical and medicine histories physical exam and vital signs electrocardiograms (to measure heart function) assessment of their ability to perform daily activities blood and urine tests assessment of their general well-being. Participants will visit the Clinical Center every 2 weeks for the first 2 months. Then they will visit every 4 weeks. Participants will take ibrutinib by mouth once every day of every cycle. One cycle is 28 days. Treatment will last up to 2 years. Participants will keep a medicine diary. Participants will take tests to measure lung function. They may have computed tomography scans of their chest. They will complete questionnaires about their symptoms and how cGVHD is affecting their body and quality of life. They will repeat the screening tests. Participants may have optional blood tests and/or skin biopsies to better understand the drug s effect on the body. Participants will be contacted by phone 30 days after treatment ends. They will also be contacted once a year for 2 years to discuss how they are feeling and if they have taken any other medicines to treat cGVHD.
The purpose of this study is to evaluate the efficacy of SHR0302 in combination with Prednisone as first line therapy in patients with moderate to severe chronic graft-versus-host disease (GVHD).
Dendritic cells (DCs) serve as sentries for the immune system. DCs recognize foreign compounds (antigens) in the body, which they internalize and process. When DCs uptake foreign antigens, they migrate to secondary lymphoid organs, where the processed antigens are presented to T cells. Various DC subsets with unique cell lineages, surface protein markers, and tissue localization determinants have been identified. For example, Langerhans cells (LCs) and interstitial dendritic cells (intDCs) are DCs found in stratified epithelia, such as the skin. Though both are expressed in the skin, they differ with respect to their origin and surface protein content and can activate distinct types of immune responses. They may also have different specificities for the capture of antigens and presentation to circulating T cells. To date, it is unknown what role, if any, the different DC populations that reside or repopulate in the skin play in the development and progression of skin graft-versus-host disease (GVHD) following bone marrow transplant.
