This study looks at whether eating cottonseed oil just three times a week can help lower cholesterol and reduce heart disease risk. Researchers will give 75 overweight or at-risk adults meal replacement shakes with different amounts of cottonseed oil for 56 days. They will measur…

This program offers extra stem cells from a half-matched family donor to patients who are getting a cord blood transplant for serious blood cancers or immune disorders. The goal is to help the bone marrow recover more quickly while the cord blood cells take over permanently. It i…

This phase 2 trial is testing the drug mirdametinib in 40 people aged 2 and older with Langerhans cell histiocytosis or similar disorders. The goal is to see if this oral medication works better and has fewer side effects than current treatments. Participants take the drug twice …

This early-stage trial tests whether adding special cells (DUOC-01) into the spinal fluid is safe for children with inherited metabolic diseases that damage the brain. Participants are ages 1 week to 21 years and are already receiving a standard umbilical cord blood transplant. T…

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 better understand and treat people with certain inherited metabolic or genetic disorders. Researchers will use standard medical tests like blood work and imaging to diagnose and care for participants, who may also join other related studies. The goal is to expa…

This study looks at children with suspected or confirmed genetic and metabolic disorders to find new disease-causing gene mutations. Researchers will analyze blood samples for DNA and metabolites, and in some cases take a small skin sample. The goal is to better understand these …

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 at Necker Hospital in Paris is checking how well patients with inherited metabolic diseases follow their daily oral medication routines. About 200 patients (children aged 7 and up, teens, and adults) will fill out a questionnaire during a regular visit. The goal is to …

This study enrolls up to 15,000 children with known or suspected endocrine or metabolic disorders, along with their family members. Researchers will collect medical records, blood, saliva, and other samples to identify genetic changes linked to these conditions. The goal is to be…

This study is creating a large collection of blood, urine, stool, and heart tissue samples from 10,000 people with and without heart or metabolic conditions. The goal is to store these samples along with medical information to speed up future research into what causes these disea…

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 tests a new communication tool called 'Let's Get REAL' that helps children and teens (ages 8-17) and their families talk together about stem cell transplant or cellular therapy decisions. The goal is to see if the tool is easy to use and helpful for families. About 60 …

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 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 uses MRI scans to look for brain differences in people with metabolic diseases compared to healthy volunteers. Researchers will track changes over time and link them to body fat and other health measures. About 126 adults will take part at Ulm University Hospital. No d…

This study aims to find out how many people with an enlarged spleen or certain blood disorders (like multiple myeloma) also have Gaucher disease or acid sphingomyelinase deficiency (ASMD). Researchers will use a simple blood spot test to check for these rare conditions. The goal …

This study looks at how often young children (ages 1 to 6) with inherited metabolic diseases develop eating disorders when they are on special diets. Researchers will use a feeding scale to measure eating problems in 200 children. The goal is to understand the link between these …

This study follows up to 10 children under 2 years old with acid sphingomyelinase deficiency (ASMD) who are already receiving olipudase alfa (Xenpozyme®) as part of their routine care. Researchers will monitor side effects and immune responses over 1 to 3 years. No new treatment …

The SMILE study is tracking 10,000 adults aged 18 and older to see how sarcopenia (age-related muscle loss) and metabolic diseases like diabetes influence overall health and lifespan. Researchers will collect data from medical records, tests, and surveys over time. This is an obs…

This study looks at how lipoproteins—tiny particles that carry cholesterol in the blood—work in healthy people and those with lipid disorders like high cholesterol. The goal is to understand how these particles affect heart and blood vessel health, especially when they don't func…
