Clinical Trial Summary

Evaluate the clinical progression in patients with MPS IIIA who are untreated with any investigational product and to obtain standardized assessments: neurocognitive, behavioral, sleep-wake habits and effect of MPS IIIA on the quality of life of patients and their families.


Description:

This is a multicenter, multinational, longitudinal, observational study in children aged up to and including 9 years, who have been diagnosed with MPS IIIA. The study will detail the natural course of MPS IIIA via standardized clinical, biochemical, neurocognitive, developmental, behavioral and imaging measures. This information is anticipated to inform the design and interpretation of future interventional studies.
