Secondary hemophagocytic lymphohistiocytosis

This phase 3 trial tests a drug called plonmarlimab in 30 adults with a severe immune overreaction (macrophage activation syndrome) linked to rheumatic diseases that hasn't responded to prior treatment. Participants receive weekly IV infusions for 8 weeks. The main goal is to see…

This study tests a bone marrow transplant from a family donor for children under 21 with severe non-cancer blood disorders like sickle cell disease, bone marrow failure, or immune problems. The goal is to see if the transplant can replace the diseased cells with healthy donor cel…

This study tests a new drug, ELA026, for people with secondary hemophagocytic lymphohistiocytosis (sHLH), a rare and life-threatening condition where the immune system becomes dangerously overactive. The drug aims to calm this overreaction by removing certain immune cells. The tr…

This study tests a drug called ruxolitinib as the first treatment for children with a rare, life-threatening immune condition called primary HLH. The goal is to calm the overactive immune system and help more children survive long enough to receive a stem cell transplant. The tri…

This study tests whether the drug letermovir can prevent serious viral infections in children with EBV-related blood disorders who receive a stem cell transplant. About 80 children will be enrolled, and researchers will monitor for infections and other transplant complications. T…

This study tests whether a transplant of donated umbilical cord blood can help people aged 14 to 80 with serious diseases caused by the Epstein-Barr virus (EBV), such as certain lymphomas or chronic active EBV infection. The goal is to control the disease and improve survival, bu…

This study tests a combination of two drugs, zanubrutinib and rituximab, for people with B-cell lymphoma who develop a severe immune overreaction called hemophagocytic lymphohistiocytosis (HLH). The trial will enroll 40 participants and aims to see how well the treatment controls…

This study is looking for a better way to diagnose three serious conditions that can look alike: Still's disease, sepsis, and macrophage activation syndrome. Researchers will measure a specific form of a blood protein called glycosylated ferritin in 60 people suspected of having …

This study tests a new type of ultrasound called super-resolution ultrasound (SRUS) to see if it can better tell the difference between benign (non-cancerous) and malignant (cancerous) swollen lymph nodes. About 779 adults with abnormal lymph nodes will receive an injection of ul…

This study aims to learn more about how diseases related to blood clots, the immune system, and blood vessels start and change over time. Researchers will enroll up to 1,000 people aged 5 and older, including those with these conditions, their healthy relatives, and healthy volun…

This study looks for better ways to detect lung inflammation and infections early in people who have received a stem cell transplant from a donor. About 40 participants aged 5 to 70 will get regular lung scans, breathing tests, blood draws, and a procedure where a tube collects f…

This study is following 81 adults with a rare condition called hemophagocytic lymphohistiocytosis (HLH), where the immune system becomes dangerously overactive. Researchers aim to better understand the disease's features and how patients respond to treatments like steroids and ch…

This study is testing a tool called B-COMPASS that uses a 22-question survey to predict whether people will follow their prescribed treatments. Researchers will enroll 3100 adults with cardiovascular, endocrine, immune, nerve, cancer, or rare diseases across Europe. The goal is t…

This study aims to understand why some adults develop secondary hemophagocytic lymphohistiocytosis (sHLH), a serious immune condition causing fevers and organ damage. Researchers will follow 300 participants for up to 3 years, collecting blood samples and medical data to identify…

This study is creating a large registry of 800 people receiving biologic medications for immune conditions like autoimmune diseases and primary immune deficiencies. Researchers will collect blood samples and health data to better understand how these treatments work and who respo…

This study collects information from about 100 adults in Alsace who have had a confirmed case of human anaplasmosis, a bacterial infection spread by ticks. Researchers want to learn more about how common it is, what symptoms people have, and how serious it can be. The goal is to …
