Homozygous familial hypercholesterolemia

This study tests a new type of stem cell transplant for children with primary immune deficiencies or inherited metabolic disorders. The transplant uses stem cells from a half-matched family donor, which are specially processed to remove certain immune cells. The goal is to see if…

This study tests a new medicine called zodasiran in people aged 12 and older who have a rare genetic condition that causes extremely high cholesterol (homozygous familial hypercholesterolemia). The goal is to see if the drug can safely lower bad cholesterol levels over 12 months.…

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 early-stage trial tests a new CRISPR-based treatment called CTX310 for people with severe cholesterol and triglyceride problems that don't improve with standard therapies. The treatment uses a tiny fat bubble to deliver gene-editing tools that turn off a gene linked to high …

This study tests an experimental drug called EDP167 in 20 adults with homozygous familial hypercholesterolemia (HoFH), a rare genetic condition causing very high cholesterol. The drug aims to lower harmful cholesterol levels. Participants will receive multiple injections of EDP16…

This study follows about 52 people with homozygous familial hypercholesterolemia (HoFH), a rare genetic condition causing extremely high cholesterol and early heart disease. Researchers will compare those who get evinacumab (a cholesterol-lowering antibody) added to their usual t…

This study looks at the long-term safety of inclisiran, a cholesterol-lowering injection, in children with a genetic condition that causes very high cholesterol. About 195 kids who completed earlier inclisiran studies will receive the drug for an extended period. Researchers will…

This study tests a drug called inclisiran in children aged 2 to 12 who have a rare genetic condition that causes extremely high cholesterol. The goal is to see if the drug safely lowers their bad cholesterol compared to a placebo. Participants will receive either inclisiran or pl…

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 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 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 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 creates a database of health information and blood samples from up to 60 children and adults with homozygous familial hypercholesterolemia (hoFH), a rare genetic condition causing extremely high cholesterol from birth. Researchers will track participants over time to l…

This study aims to identify different types of familial hypercholesterolemia (FH) in infants and newborns. Expectant parents with FH will provide a cheek swab for genetic testing, and their babies will have 5 blood samples collected over 2 years. The goal is to improve early dete…

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 is building a global database of 1000 people with homozygous familial hypercholesterolemia (HoFH), a rare inherited condition causing extremely high cholesterol from birth. Researchers are gathering de-identified medical data from clinics around the world to better und…

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 …

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…

This study follows 100 children under 18 who are already on a ketogenic diet for conditions like drug-resistant epilepsy, autism, chronic migraine, or brain tumors. Researchers want to see if the diet supports healthy growth, improves symptoms, and boosts quality of life. The die…
