Mucopolysaccharidosis

This study followed 21 boys with Hunter syndrome who started taking Elaprase before age 6. Researchers tracked their height and weight for at least 5 years to see if the drug helps them grow more like other children. The study also monitored safety and compared growth data to unt…

This study looked at the long-term safety and effectiveness of Hunterase (idursulfase beta) in 30 people with Hunter syndrome over about one year. Participants had either completed a previous phase 3 study or had used Hunterase for at least six months. The goal was to monitor sid…

This study tested two different chemotherapy drugs (Treosulfan and Busulfan) given before a stem cell transplant in 106 children with serious non-cancer diseases like immune disorders, metabolic diseases, blood disorders, and bone marrow failure. The goal was to see which drug le…

This study tested a drug called Aldurazyme (laronidase) in 12 Chinese people with mucopolysaccharidosis I (MPS I), a rare genetic disorder. Participants received weekly infusions for 26 weeks to see if the treatment is safe and reduces waste products in urine. The goal is to mana…

This study tested a new method called global metabolomic profiling to diagnose inborn errors of metabolism, a group of rare genetic disorders. Researchers compared this approach to traditional testing in 240 participants. The goal was to see if the new method could more accuratel…

This study created a registry of medical records from women with inborn errors of metabolism—rare conditions that affect how the body turns food into energy. Researchers collected data from past or current pregnancies and followed babies for one year after birth. The goal was to …

This completed study looked at how the social networks of caregivers affect their stress and health when caring for someone with an inherited disease. Researchers surveyed over 680 participants, including family members and formal caregivers, to understand caregiving burden and s…

This registry tracked over 1,400 people with MPS I, a rare genetic disorder, to better understand how the disease progresses and how treatments like enzyme replacement therapy work over time. It did not test a new drug but collected real-world data to help doctors improve patient…

This study tested whether a powerful DNA test called high-throughput exome sequencing can find genetic causes of multiple birth defects in fetuses when standard exams fail. Researchers studied 100 fetuses with at least two malformations and no prior diagnosis. They compared the n…

This study tested whether a fast type of genetic test called rapid genome sequencing can find the cause of birth defects seen on ultrasound more quickly than current methods. Researchers included 184 pregnancies with certain ultrasound findings. The goal was to see if results cou…

This completed study looked at whether the sedative dexmedetomidine can protect blood vessel lining during rhinoplasty. 90 patients received either standard anesthesia or dexmedetomidine plus anesthesia. Researchers measured two blood markers of vessel damage to see if dexmedetom…

This study looked at how many girls and young women aged 11 to 20 with chronic diseases (like diabetes or immune conditions) got the HPV vaccine, compared to those without chronic illness. Researchers reviewed records of 223 participants from a hospital in France. The goal was to…

This study looked at whether whole genome sequencing (a complete read of a person's DNA) can help diagnose leukodystrophies, a group of rare brain diseases that are hard to identify. Researchers enrolled 236 children with white matter abnormalities on brain scans but no known gen…

This study followed 7 adults with a milder form of Morquio A disease for 5 years to learn how the condition changes over time. Researchers measured walking ability and other health factors to better understand the disease and improve future treatment evaluations. The goal was to …
