This study aims to uncover the genetic roots of aortic aneurysms and valve disease by analyzing tissue and blood samples from 3,000 participants. Researchers will look for new disease-causing genes and factors that affect disease severity. The goal is to build a biorepository to …

This study looks at teeth misalignment and neck defects in people with moderate to severe osteogenesis imperfecta (OI), a rare condition that causes bones to break easily. Researchers will use scans of the teeth, jaw, and neck to measure these problems in 75 participants aged 10 …

This study looks at whether common osteoporosis medications also improve muscle health in adults aged 65 and older. Researchers will measure changes in muscle mass, strength, and walking speed over time. The goal is to better understand the link between bone and muscle health in …

This study looks at 100 people who spent at least a week in the ICU and had kidney injury. Researchers will measure kidney function, muscle loss, and bone health to understand long-term effects. The goal is to improve follow-up care for ICU survivors.

This lab study compares how much growth factor (PDGF-BB) is released over time from two materials used in bone grafting: platelet-rich fibrin (PRF) from a patient's blood and a commercial product called GEM21S. Researchers will mix these with bone substitutes and measure growth f…

This study is testing whether a urine test can help identify different genetic types of osteogenesis imperfecta (OI), a rare condition that causes bones to break easily. Researchers will measure certain collagen peptides in the urine of 25 people with OI. If successful, this coul…

This study was designed to test whether adding arm exercises to a standard osteoporosis medication could improve bone density in the wrist. It was planned for postmenopausal women at high fracture risk. However, the study was withdrawn before enrolling any participants, so no res…

This study aimed to see if a web-based fracture liaison service (e-FLS) could help more older adults start osteoporosis treatment after a fracture compared to standard in-person services. It planned to include men and women over 60 in France who had a low-trauma fracture. However…

This study watches how the enzyme drug laronidase moves through the bodies of 13 children with MPS IH (a rare genetic disease) before and after they get a stem cell transplant. The goal is to learn what affects drug levels, not to test a new treatment. Children aged 0-3 who are a…

This study aims to better understand Cleidocranial Dysplasia (CCD), a rare genetic condition affecting bones and teeth. Researchers will collect medical history, quality-of-life surveys, and genetic samples from 300 participants. The goal is to improve diagnosis and care for peop…

This study looks at how CFTR modulators, a type of cystic fibrosis treatment, affect bone strength and muscle mass in adults with CF. Researchers will measure changes in bone density and lean body mass over 12 to 24 months. The goal is to understand whether these treatments help …

This study was designed to see if a new monitoring algorithm could detect early signs of ovarian damage in women and girls who had cancer treatment. Researchers planned to compare a group using the new algorithm with a group that received standard care. However, the study was wit…

This study follows 60 children aged 4–10 with clubfoot to see if a new scoring system (PBS-score) can predict whether their foot condition will come back and need extra treatment like casting, braces, or surgery. Researchers will track the children for five years and also ask fam…

This study follows 226 people with X-linked hypophosphatemia (XLH) for up to 10 years. Researchers will collect data on height, walking ability, fractures, and overall health to better understand how the disease progresses and affects daily life. No new treatment is being tested;…

This study tracks bone density and fracture risk in 1,230 pregnant and breastfeeding women using ultrasound scans and diet questionnaires. The goal is to catch early signs of pregnancy-related osteoporosis, a rare condition that can cause painful fractures. No drugs or treatments…

This early-phase study looks at whether a common blood pressure drug, hydrochlorothiazide, can affect chronic pain in people who already have a spinal cord stimulator implant. About 36 adults with chronic low back pain and high blood pressure will take the drug or a placebo for t…
