Mucopolysaccharidosis Type IVA Clinical Trial
Official title:
Discovering New Biomarkers for Monitoring Disease Progression in Patients With Mucopolysaccharidosis IVA (MPSIVA)

Is FDA regulated | No |
Health authority | United States: Institutional Review Board |
Study type | Observational |
The purpose of this study is to find out more about some of the unusual chemicals (called oligosaccharides) that can occur naturally as a result of processes in the body. Researchers want to look at how these chemicals change with time and how they change between different patients with MPSIVA. These unusual chemicals were recently discovered in the urine from patients with MPSIVA. The investigators would like to study these chemicals before a specific enzyme replacement therapy is used. If the investigators understand how these chemicals change, the investigators may be able to use them to monitor this condition in the near future as well as help doctors know whether certain therapies work well in their patients.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Quantification of urinary oligosaccharides in urine from a first morning void in patients with Mucopolysaccharidosis IVA. | The variability of oligosaccharides in the same patient over different time points and urine specimen type will be evaluated. | Every 2 months over the course of a year. | No |
Secondary | Quantification of urinary oligosaccharides in urine from a random collection in patients with Mucopolysaccharidosis IVA. | The variability of oligosaccharides among different patients with MPSIVa will be evaluated. | One urine over the course of a year or 6M | No |
