- Neurocognitive function [ Time Frame: Baseline + every 24 weeks for up to 192 weeks ]A neurodevelopmental assessment will be performed using standardized developmental tests to provide quantifiable measures of neurocognitive function.
- Behavioral function [ Time Frame: Baseline + every 24 weeks for up to 192 weeks ]Disease-related behaviors will be assessed using an MPS IIIB specific behavior rating scale.
- Quality of Life Tests [ Time Frame: Baseline + every 24 weeks for up to 192 weeks ]Multiple QoL tools will be used to capture physical, mental, and social well-being of the patient as well as to examine the impact of the patient's disease on the parent/guardian and family.
- Sleep habits [ Time Frame: Baseline + every 24 weeks for up to 192 weeks ]Patient sleep habits will be assessed using Children's Sleep Habits Questionnaires (CSHQ).
- Disease-specific Biomarkers [ Time Frame: Baseline + every 24 weeks for up to 192 weeks ]Urine sample for glycosaminoglycans (GAGs) and creatinine.
- Biochemical, Molecular, Cellular and Genetic Markers of Disease Burden [ Time Frame: Once (at baseline visit) ]Blood and urine samples will be used to evaluate biochemical, molecular cellular, and genetic/genomic aspects of MPS IIIB.
