What this Trial Is About

Researchers are studying Mucopolysaccharidosis VII (MPS VII), also known as Sly Syndrome, to understand how the disease presents and progresses over time. This global, prospective, multicenter, and longitudinal program aims to assess the long-term effectiveness and safety of the treatment vestronidase alfa, including monitoring for hypersensitivity reactions and immune responses. Both treated and untreated patients with MPS VII are included to gather a comprehensive understanding of the disease. The program includes patients receiving vestronidase alfa either through prescription or early access/compassionate use, as well as patients who are untreated or receiving treatments other than vestronidase alfa. This is an observational study without randomization, designed to collect standardized high-quality data from multiple global sites. Treatments are not assigned by the study but observed as part of routine care or compassionate use. Participants will be monitored over a period of 10 years to track the clinical course of MPS VII, the long-term effectiveness of vestronidase alfa, and its safety profile. Data collection includes biomarker analysis, clinical assessments, and patient or caregiver-reported outcomes. The study aims to provide detailed insights into disease heterogeneity and progression by gathering consistent and meaningful data during routine clinical visits.
