The total study duration per participant was 4 to 8 weeks that consisted of a screening period (from 2 days to 4 weeks), treatment visit (1 day), and a follow up call (greater than or equal to 30 days). Two participants enrolled prior to protocol amendment 2 (dated 17 December 2015), which changed the study to single-dose, and were treated for 26 weeks, with a 4-week follow up.
151 studies on the registry are indexed under Glycogen Storage Disease Type II; 30 are open to participants now.

The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
Participants received intravenous (IV) infusion of Alglucosidase alfa 20 milligrams per kilogram (mg/kg) body weight on Day 1. Infusion was administered at an initial rate of approximately 1 milligram per kilogram per hour (mg/kg/hr) with allowed rate increased of 2 mg/kg/hr every 30 minutes, if there were no signs of infusion-associated reactions (IARs), until a maximum rate of approximately 7 mg/kg/hr was reached.
