A Phase 4 Prospective Exploratory Muscle Biopsy, Biomarker, and Imaging Assessment Study in Patients With Late-Onset Pompe Disease Treated With Alglucosidase Alfa
This is an open-label, multicenter study of participants with late-onset Pompe disease naive to treatment with enzyme replacement therapy (ERT). The primary objective of this study is to evaluate glycogen clearance in muscle tissue samples collected pre and post alglucosidase alfa treatment in participants with Late-Onset Pompe disease. The secondary objectives are to characterize the disease burden in participants with late-onset Pompe disease and explore imaging, histologic, and functional assessments in these participants and to explore potential plasma or urine biomarkers relative to late-onset Pompe disease and participant's response to treatment with alglucosidase alfa (Myozyme®/Lumizyme®/GZ419829).
