Phosphorus metabolism disease

This study tests a new drug called AP306 in 168 adults on maintenance hemodialysis who have high phosphate levels (hyperphosphatemia). Participants take one of several fixed doses of AP306 or a placebo daily for 8 weeks. The main goal is to see if AP306 safely lowers blood phosph…

This study tests whether dipyridamole, a drug usually used for heart conditions, can raise low phosphate levels in kidney transplant recipients. Researchers will give the drug to 90 adult patients when their phosphate drops below normal. The goal is to see if it improves phosphat…

This study tests a new drug called TS-172 in 30 adults on peritoneal dialysis who have high phosphorus levels. Participants take the drug daily for several weeks to see if it can safely bring their phosphorus down to a target range. The goal is to find a better way to manage this…

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 called TS-172 in 30 adults on hemodialysis who have high phosphate levels. Participants take the drug daily for a period, and researchers check if their phosphate levels drop to a target range. The goal is to see if TS-172 can help control phosphate, a…

This study tests an experimental drug called TS-172 in 100 adults on hemodialysis who have high phosphorus levels. Participants will take TS-172 or a placebo alongside their usual phosphate binders. The goal is to see if TS-172 helps more patients reach safe phosphorus levels, wh…

This phase 3 trial tests whether AP301, a drug taken with meals, can safely lower high blood phosphate in people on kidney dialysis. About 264 participants will receive either AP301 or a low-dose version for 8 weeks, then all get AP301 for 24 weeks. The goal is to see if AP301 he…

This phase 3 study tests a new drug called TS-172 in 300 adults on hemodialysis who have high phosphate levels. Participants take the pill daily for up to a year to see if it safely and effectively controls phosphate. The goal is to offer a better treatment option for a common co…

This study tests whether a phosphate supplement in granule form can safely raise low blood phosphate levels in 60 ICU patients. Participants take the granules daily for up to 14 days, with doses adjusted based on how low their phosphate is. Researchers will check blood levels dai…

This study tests a new drug called KK8123 for adults with X-linked hypophosphatemia (XLH), a rare genetic condition that causes low phosphate levels and bone problems. The trial has two parts: first, finding the right dose, then checking safety and how well it works over time. Ab…

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 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 looks at how long-term phosphate therapy affects the kidneys, blood vessels, and heart in people with two rare bone disorders: X-linked hypophosphatemia (XLH) and hereditary hypophosphatemic rickets with hypercalciuria (HHRH). Researchers will measure hormone levels an…

XLH is a rare genetic condition that causes low phosphate levels, leading to weak bones and pain. Burosumab is a standard treatment, but the best starting dose is still unclear. This study will review the medical records of 120 children across England to see if a lower dose (unde…

This study is collecting blood and other samples from 5,000 children and young adults (under 21) who are already taking certain medications as part of their regular care. The goal is to understand how these drugs move through and affect children's bodies, so doctors can prescribe…

This study looks at whether eating too much phosphate—common in many US diets—can reduce your ability to exercise and increase belly fat. Researchers will measure oxygen use during cycling and energy production in muscles. About 124 healthy adults will take part to see if finding…

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…

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 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…
