Renal tubule disorder

This early-stage trial tests a daily capsule called NDI-5001 in 24 adult men with a rare inherited kidney condition (X-linked congenital nephrogenic diabetes insipidus) that causes extreme thirst and frequent urination. The study's main goal is to check the drug's safety and how …

This study tests a gene therapy called DFT383 in 30 children aged 2 to 5 with nephropathic cystinosis, a rare disease that damages kidneys and other organs. The treatment aims to fix the genetic problem so children may no longer need daily cysteamine medication. Researchers will …

This study tests whether injecting sodium thiosulfate directly into abnormal calcium deposits can shrink them and reduce pain. It includes people with three rare conditions: systemic sclerosis, dermatomyositis, and a genetic disorder called iPPSD2. Participants receive up to 11 i…

This study tests an experimental drug called IG3018 for people with high uric acid, some of whom also have chronic kidney disease. About 60 adults will receive either the drug or a placebo for 4 weeks. Researchers will check safety, side effects, and how well the drug lowers uric…

This study tests whether the diabetes drug empagliflozin (Jardiance) can safely raise low sodium levels in people with certain conditions like SIADH, liver failure, or kidney failure. About 172 adults with chronic low sodium will receive either the drug or a placebo for up to 30 …

This study aims to see if a home lactate meter and a standard glucose meter give accurate readings compared to lab tests in people with glycogen storage disease types Ia, Ib, and XI. Ten participants will have an 8-hour hospital stay with hourly blood draws and finger-stick tests…

This study aims to learn more about rare disorders that affect how the body processes chemicals called pyrimidines and purines. These disorders can cause problems in the brain, blood, kidneys, and immune system, ranging from mild to life-threatening. Researchers will compare test…

This study follows people with rare inherited forms of kidney stones and chronic kidney disease, such as primary hyperoxaluria, cystinuria, and Dent disease, to learn how these conditions develop over time. Researchers will measure markers of inflammation in blood and urine and t…

This study follows up to 3,000 people who have, are at risk for, or are related to someone with a parathyroid disorder. Researchers will collect medical records, questionnaires, and samples like blood and saliva to learn what causes these conditions and how they change over time.…

This study creates a biobank of blood, urine, and tissue samples from people with rare kidney stone diseases—primary hyperoxaluria, cystinuria, APRT deficiency, and Dent disease—and their family members. By storing these samples, researchers hope to enable future studies that cou…

This study collects medical information from people around the world who have one of four rare hereditary kidney stone diseases: primary hyperoxaluria, Dent disease, cystinuria, or APRT deficiency. By gathering data from many patients, researchers hope to better understand how th…

This study is creating a central database and tissue bank for rare diseases affecting the kidneys and liver, such as ARPKD and Joubert syndrome. Researchers will collect medical information, genetic samples, and tissues from 200 participants to help doctors and scientists better …

This study aims to find the specific genes and mutations that cause rare, inherited forms of kidney stone disease. Researchers will analyze DNA from up to 6,000 participants to understand how these genetic changes lead to stones. The goal is to use this knowledge to develop bette…

This study looks at whether breathing a lighter gas mixture (heliox) can make it easier to breathe and think clearly when breathing is hard. Fifteen healthy adults will breathe normal air or heliox while doing thinking tests. The goal is to see if reducing the work of breathing i…

This observational study will follow 2000 children and adults with imprinting disorders—rare genetic conditions like Silver-Russell and Prader-Willi syndromes. Researchers aim to describe the natural history of these diseases and identify common metabolic profiles, risks for obes…

This study at the University of Michigan is testing whether ultrasound can monitor bone graft healing after tooth extraction, potentially replacing more invasive scans. About 140 adults needing a tooth extraction and bone graft for a future dental implant will have their healing …

This study looks at the genetic causes of nephronophthisis, a rare kidney disease that leads to kidney failure before age 20. Researchers will collect urine and blood samples from 310 patients and healthy relatives to study cells and identify potential drug targets. The goal is t…
