Mucopolysaccharidosis

This program provides expanded access to Mepsevii for people with MPS VII (Sly Syndrome) who have no other treatment options. It is designed for individual patients on a case-by-case basis. The goal is to offer a potential treatment when no alternatives exist.

This early-access program tests whether a weekly infusion of tralesinidase alfa directly into the brain's fluid spaces is safe and tolerable for children with Sanfilippo syndrome type B, a rare genetic disorder that causes severe neurological decline. The study enrolls about 10 c…

This early-stage study tests whether ISP-001 is safe and tolerable in 11 people with a rare genetic disease called MPS I (Hurler-Scheie or Scheie types). Participants receive the experimental treatment and are monitored for side effects. The goal is to gather safety data for futu…

This trial tests a one-time gene therapy called UX111 for children with Sanfilippo A, a rare genetic disorder that causes severe brain damage. The therapy delivers a working copy of the missing gene to cells. Researchers will measure whether it reduces harmful substances in the b…

This program offers continued treatment with idursulfase-IT (TAK-609), given directly into the spinal fluid, plus standard intravenous Elaprase, for children and adults with Hunter syndrome who have cognitive impairment. It is only open to people who completed earlier studies of …

This study tests whether giving enzyme replacement therapy to fetuses with certain rare genetic diseases (like MPS I, Gaucher, or Pompe) before birth is safe and feasible. About 10 pregnant participants will receive the treatment through the umbilical vein. The goal is to see if …

This study is testing a less intense chemotherapy and radiation regimen before a stem cell transplant for children and young adults up to age 55 with non-cancerous blood disorders like immune deficiencies, anemias, and metabolic diseases. The goal is to see if this gentler prepar…

This early-stage trial tests whether adding special cells (DUOC-01) into the spinal fluid is safe for children with inherited metabolic diseases that damage the brain. Participants are ages 1 week to 21 years and are already receiving a standard umbilical cord blood transplant. T…

This early-phase study tests a new drug called JR-446 in 10 children with mucopolysaccharidosis type IIIB (Sanfilippo syndrome type B), a rare genetic disease that affects the brain and body. The drug is given through an IV and aims to be safe and possibly help manage the conditi…

This study tests whether cannabidiol (CBD) can safely improve behavior, mood, sleep, and daily function in people with Sanfilippo syndrome, a rare genetic disorder. Thirty-five participants will receive either CBD or a placebo, then switch after a break. Caregivers will report on…

This study monitors up to 50 people with MPS VII (Sly Syndrome) to understand how the disease changes over time. It also checks the long-term safety and effectiveness of the drug vestronidase alfa. Participants may or may not be taking the drug, and the study involves regular che…

This study is for children with Morquio A, a rare genetic disease that affects bones and breathing. Researchers will use safe, non-invasive tests like MRI, X-rays, hearing tests, and walking analysis to track how the disease changes over time. The goal is to better understand the…

This study follows 30 children and young adults with Sanfilippo syndrome type C, a rare genetic disorder that causes severe brain damage. Researchers will measure changes in development and thinking skills over time using standard tests. The goal is to better understand how the d…

This study collects information from up to 250 patients with lysosomal storage diseases (like certain forms of MPS, Pompe, Gaucher, and Wolman disease) to understand how these conditions develop and respond to treatments given before birth. Researchers will track symptoms, lab re…

This observational study will follow up to 1,000 people in France with mucopolysaccharidosis (MPS), a group of rare genetic disorders. Researchers will collect medical data from patient records and ongoing checkups to map how the diseases progress and how current treatments affec…

This study follows 1500 people with rare genetic brain disorders to learn how these diseases progress. Researchers measure thinking, movement, and daily living skills over time, and also look at brain scans and body fluids. The goal is to better understand the diseases and how tr…

This study looks at how heart and blood vessel problems develop in people with MPS I and IVA. Over 4 years, 240 participants will get yearly heart ultrasounds, blood tests, and urine tests. The goal is to find reliable markers that can track heart health and guide future treatmen…

This study collects medical information and biological samples (like blood or tissue) from up to 12,000 people with leukodystrophies—rare disorders that damage the brain's white matter. Researchers will use this data to find new genetic causes, develop biomarkers for future trial…
