  • The primary objective of this study is to characterize the pharmacokinetics of alglucosidase alfa manufactured at the 4000 L scale in patients 8 years of age and older who have a confirmed diagnosis of Pompe disease.
  • A secondary objective of this study is to evaluate and explore the relationship between anti-rhGAA antibody titers and the pharmacokinetics of alglucosidase alfa.

Primary Outcome Measures:
  • Maximum observed concentration (Cmax) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Actual sampling time to reach maximum observed concentration (Tmax) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Area under the concentration-time curve from 0 to the time of the last quantifiable concentration (AUC last) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Area under the concentration-time curve from time 0 and extrapolated to infinite time (AUC inf) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Terminal elimination half-life (T1/2) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Total systemic clearance (CL) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Volume of distribution (Vd) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Pharmacokinetic (PK) parameters assessed in relation to anti-rhGAA antibody titers [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Pharmacokinetic (PK) parameters assessed in relation to inhibitory/neutralizing anti-rhGAA antibody titers [ Time Frame: Day 1 ] [ Designated as safety issue: No ]

Estimated Enrollment: 20
Study Start Date: November 2014
Estimated Study Completion Date: January 2018
Estimated Primary Completion Date: January 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: alglucosidase alfa
alglucosidase alfa intravenous (IV) infusion of 20mg/kg body weight
Biological: alglucosidase alfa
Intravenous (IV) infusion of 20mg/kg body weight every other week (qow)
Other Name: Lumizyme

Detailed Description:
The total study duration per patient will be 4 to 9 weeks that consist of a screening period (from 2 days to 4 weeks), treatment visit (1 day), and a follow up call (≥30 days).

Ages Eligible for Study:   8 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • A patient must meet all of the following criteria to be eligible for this study.
  • The patient and/or the patient's parent/legal guardian is willing and able to provide signed informed consent.
  • The patient is ≥8 years of age with confirmed acid α-glucosidase (GAA) enzyme deficiency from skin, blood, or muscle tissue and/or 2 confirmed GAA gene mutations.
  • The patient, if female and of childbearing potential, must have a negative pregnancy test (urine beta-human chorionic gonadotropin) at baseline. Note: All female patients of childbearing potential and sexually mature males must agree to use a medically accepted method of contraception throughout the study.
  • For patients previously treated with alglucosidase alfa the patient has received alglucosidase alfa for at least 6 months.

Exclusion Criteria:

  • A patient who meets any of the following criteria will be excluded from this study.
  • The patient is participating in another clinical study using an investigational product.
  • The patient, in the opinion of the Investigator, is unable to adhere to the requirements of the study.

The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
