Hypophosphatasia

This phase 3 trial tests an experimental drug called ALXN1850 in 124 adolescents and adults with hypophosphatasia, a rare genetic bone disease. Participants receive either the drug or a placebo by injection under the skin. The main goal is to see if the drug improves walking dist…

This study tests a new drug called ALXN1850 in children aged 2 to 12 with hypophosphatasia, a rare genetic condition that weakens bones. The trial compares the drug to a placebo to see if it improves bone health and movement. About 30 children who have not received prior treatmen…

This study compares a new medicine, ALXN1850, to the current standard treatment (asfotase alfa) in 43 children aged 2 to 12 with hypophosphatasia, a rare genetic condition that weakens bones. All children have been on the standard treatment for at least 6 months before joining. T…

This study planned to test a combination of immunosuppressive drugs (methotrexate, rituximab, bortezomib, IVIg, and folic acid) in people with hypophosphatasia whose bodies had stopped responding to asfotase alfa due to antibodies. The goal was to see if suppressing the immune sy…

This study offers voluntary screening for newborns in North Carolina to detect a wide range of rare health conditions early. Using a small blood sample already collected at birth, the program tests for dozens of disorders, including spinal muscular atrophy, cystic fibrosis, and m…

This study tests new vitamin and mineral supplements called EasiVits for children aged 1-16 with inborn errors of metabolism (IEM). These supplements have less carbohydrate and no flavor, so they can be used with different diets and kids can add their own taste. The goal is to se…

This study will collect and analyze genetic data from 1000 people with suspected inherited metabolic diseases, including conditions like epilepsy and mitochondrial disorders. Researchers at Karolinska University Hospital aim to improve diagnosis by using advanced genetic testing …

This study was designed to track how COVID-19 infection might worsen the condition of people with inherited metabolic diseases (IMD). Researchers planned to collect information from French patients with IMD who had or had COVID-19 to see how often their metabolic disease got wors…

This long-term study follows over 1,500 people of all ages with hypophosphatasia (HPP), a rare bone disease. Researchers will collect information on how the disease progresses, its impact on daily life, and the long-term safety and effectiveness of the treatment asfotase alfa. Th…
