Description

Summary

This is a four-part prospective, multicenter, multiregional observational study of patients with mucopolysaccharidosis type II (MPS II), also known as Hunter syndrome, to assess biomarkers potentially related to disease severity and/or treatment response and prospectively assess the progression of disease in participants with MPS II who are aged 2 through 10 years (Part 1), 2 through 30 years (Part 2), < 8 years (Part 3), and 6 to < 17 years (Part 4) at the time of enrollment.

Open to people ages up to 30 years

(Part 1):

- Participants aged 2 through 10 years - nMPS II subgroup: participants with a development quotient (DQ) <85 and/or a decline of at least 7.5 points in DQ, assessed at least 6 months apart, or with the same genetic mutation as a blood relative with confirmed nMPS II Key Inclusion Criteria (Part 2): - Participants aged 2 through 30 years - nMPS II subgroup: patients with an age-adjusted DQ <85 and/or a decline of 10 points or more in DQ in the previous 6 months or more, or with the same genetic mutation as a blood relative with confirmed nMPS II - Scheduled to undergo general anesthesia or CSF sampling for non-study-related medical reasons and parent(s)/legally authorized representative consent to donate CSF for research purposes during that procedure, or an adult patient is able to provide consent and agrees to participation in the study for CSF collection/donation Key Inclusion Criteria (Part 3): - nMPS II participants aged <8 years Key Inclusion Criteria (Part 4): - nnMPS II participants aged 6 to 17 years

You CAN'T join if...

(All Parts):

- Have unstable medical condition that would make participation in the study unsafe or would interfere with necessary medical care - Have received any central nervous system (CNS)-targeted MPS II investigational therapy within the previous 6 months
