Study Summary

Pompe disease (also known as glycogen storage disease Type II) is caused by a deficiency of a critical enzyme in the body called acid alpha-glucosidase (GAA). Normally, GAA is used by the body's cells to break down glycogen (a stored form of sugar) within specialized structures called lysosomes. In patients with Pompe disease, an excessive amount of glycogen accumulates and is stored in various tissues, especially heart and skeletal muscle, which prevents their normal function. The objective of this extension study is to assess the long-term safety and efficacy of alglucosidase alfa treatment in patients with Late-Onset Pompe Disease who were previously treated under the placebo-controlled, double-blind study AGLU02704 (NCT00158600).

Primary Outcome

The numbers of participants who experienced Adverse Events (AEs), Serious Adverse Events (SAEs), treatment-related AEs, and Infusion Associated Reactions (IARs). Summary is based on treatment-emergent AEs (TEAEs), defined as AEs that occurred following the initiation of study treatment with alglucosidase alfa. Participants with long-term exposure to alglucosidase alfa (those from the Alglucosidase Alfa/Alglucosidase Alfa treatment group) are included. Time frames are stated from the start of th
