Clinical Trial Summary

- The primary objective of this study was to characterize the pharmacokinetics (PK) of alglucosidase alfa manufactured at the 4000 L scale in participants who had a confirmed diagnosis of Pompe disease. - A secondary objective of this study was to evaluate and explore the relationship between anti-recombinant human acid alpha-glucosidase antibody titers and the PK of alglucosidase alfa.

Description:

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.

Eligibility

Inclusion Criteria:

A participant was to meet all of the following criteria to be eligible for this study:

• The participant and/or the participant's parent/legal guardian was willing and able to provide signed informed consent.
• The participant had a confirmed acid alpha-glucosidase (GAA) enzyme deficiency from skin, blood, or muscle tissue and/or 2 confirmed GAA gene mutations.
• Infant and toddler Pompe disease participants could be included in the study only under condition (minimal body weight) that the trial-related blood loss (including any losses in the maneuver) would not exceed 3 percent (%) of the total blood volume during a period of 4 weeks and would not exceed 1 % at any single time.
• The participant, if female and of childbearing potential, must have had a negative pregnancy test (urine beta-human chorionic gonadotropin) at screening. Note: All female participants of childbearing potential and sexually mature males must have agreed to use a medically accepted method of contraception throughout the study.
• For participants previously treated with alglucosidase alfa the participant had received alglucosidase alfa for at least 6 months. Exclusion Criteria:

A participant who met any of the following criteria was excluded from this study:

• The participant was participating in another clinical study using an investigational product.
• The participant, in the opinion of the Investigator, was unable to adhere to the requirements of the study. The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.

Primary	Pharmacokinetics: Time to Reach Maximum Observed Plasma Concentration (Tmax) of Alglucosidase Alfa	Tmax was defined as time to reach maximum observed plasma concentration.	Pre-dose and at 1, 2, 4, 8, 12, and 24 hours Post-dose on Day 1
Primary	Pharmacokinetics: Area Under the Plasma Concentration-Time Curve (AUC) of Alglucosidase Alfa	AUC was defined as area under the plasma concentration-time curve from time 0 to 24 hours post-dose.	Pre-dose and at 1, 2, 4, 8, 12, and 24 hours Post-dose on Day 1
Primary	Pharmacokinetics: Area Under the Concentration-time Curve From Time 0 to the Time of the Last Quantifiable Concentration (AUC0-last) of Alglucosidase Alfa	AUC0-last was defined as area under the concentration-time curve from time 0 to the time of the last quantifiable concentration.	Pre-dose and at 1, 2, 4, 8, 12, and 24 hours Post-dose on Day 1
