Mucopolysaccharidosis VII Disease Monitoring Program

The Mucopolysaccharidosis VII Disease Monitoring Program (MPS VII DMP) is a global, prospective, multicenter, longitudinal protocol designed to characterize MPS VII disease presentation and progression, assess long-term effectiveness and safety of vestronidase alfa, including hypersensitivity reactions and immunogenicity , as well as prospectively investigate longitudinal change across biomarker(s), clinical assessments, and patient/ caregiver-reported outcome measures in a representative population. The aim of this DMP is to collect data on patients with MPS VII to provide a comprehensive dataset on the clinical presentation, heterogeneity, and disease progression, and meaningful standardized ICH GCP-quality data collected in-clinic across multiple sites globally. The DMP is not a randomized study and both treated and untreated patients will be enrolled.

• No Intervention (Other): Access to any treatment is through authorized commercial use or available expanded access programs only and not as a part of this DMP.

Primary outcomes

• Clinical Course of MPS VII Disease [10 years]: To characterize MPS VII disease presentation and progression over time in patients treated and not treated with vestronidase alfa
• Long-term Effectiveness of Vestronidase Alfa [10 years]: To evaluate longitudinal change in biomarker(s), clinical assessments and patient/caregiver reported outcomes to examine the effectiveness of vestronidase alfa
• Long-term Safety of Vestronidase Alfa [10 years]: Hypersensitivity reactions, immunogenicity and other safety outcomes will be assessed to examine the long-term safety of vestronidase alfa.

Sex: All
