Inborn disorder of amino acid metabolism

This study tests a new microtablet protein substitute for people with phenylketonuria (PKU), a condition requiring a strict low-protein diet. The microtablets combine protein with vitamins and minerals, aiming to be easier to take than current liquid or powder options. About 20 a…

This early study tests a drug called piclidenoson in 5 adult men with Lowe syndrome, a rare genetic disorder that harms the kidneys. The goal is to see if the drug can improve how the kidneys reabsorb important small proteins over 6 months. Researchers will also check safety and …

This early-phase trial tests a single injection of a gene therapy called GS1168 in 9 adults with PKU whose condition is not well controlled by diet or other treatments. The therapy uses a harmless virus to deliver a working copy of the PAH gene, which is faulty in PKU, to help th…

This phase III trial tests a vitamin B12 injection (hydroxocobalamin chloride) in 20 children aged 6 months to 18 years with a specific type of methylmalonic acidemia (cobalamin C deficiency). The goal is to see if the injection can normalize levels of certain acids in the blood …

This study will test a new device called PheCheck™ that measures phenylalanine levels from a single fingerstick drop of blood. About 60 people with PKU or hyperphenylalaninemia, aged 1 year and older, will use the test at home and compare results to standard lab testing. The goal…

This study tests a drug called N-acetyl-L-leucine for people aged 4 and older with CACNA1A gene disorders, which can cause coordination problems, dizziness, and migraines. About 60 participants will receive either the drug or a placebo, then switch, to see if it improves movement…

This early-stage trial tests a new robotic surgical method for esophageal cancer that avoids cuts between the ribs, which may cause less chest pain and faster recovery. About 31 adults with stage I to III esophageal cancer will be randomly assigned to either the new approach or s…

This study measures specific substances (metabolites) in the breath and blood of people with inherited metabolic disorders, those on a special ketogenic diet for epilepsy, and healthy volunteers. The goal is to see if a simple breath test can reliably track these metabolites, pot…

This study looks at whether mindfulness-based stress reduction can help Black teenage girls who have been involved with the justice system and their parents or caregivers. About 90 participants will report on stress, PTSD symptoms, and other outcomes before and after the program.…

This study looks at how blood phenylalanine (Phe) levels affect thinking, emotions, and daily functioning in adults with PKU. Researchers will ask 30 adults with PKU and their relatives to complete questionnaires. The goal is to understand why some people with high Phe levels hav…

This study tests a new DNA sequencing method that reads long stretches of DNA to find hidden genetic changes causing rare diseases like albinism and intellectual disability. Researchers will analyze stored blood or DNA from 150 patients who haven't gotten a clear diagnosis yet. T…

This study will look at 225 adults with diabetic retinopathy to find out how many also develop an epiretinal membrane — a thin, scar-like layer on the retina that can blur vision. Researchers will use eye scans to detect the membrane and check for related factors like age, diabet…
