Brief summary

The objectives of this study are to characterize MPS VII disease presentation and progression and assess long-term effectiveness and safety, including hypersensitivity reactions and immunogenicity of vestronidase alfa.

Detailed description

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.
