4.Subject must have a diagnosis of LOPD based on documentation of one of the following:
a.deficiency of GAA enzyme
b.GAA genotyping
5.Subject is classified as one of the following with respect to ERT status:
a.ERT-experienced, defined as currently receiving standard of care ERT (alglucosidase alfa) at the recommended dose and regimen (ie, 20 mg/kg dose every 2 weeks) for >= 24 months
b.ERT-naive, defined as never having received investigational or commercially available ERT
6.Subject has a sitting FVC >= 30% of the predicted value for healthy adults (National Health and Nutrition Examination Survey III) at screening.
7.Subject performs two 6MWTs at screening that are valid, as determined by the clinical evaluator, and that meet all of the following criteria:
a.both screening values of 6MWD are >= 75 meters
b.both screening values of 6MWD are <= 90% of the predicted value for healthy adults
c.the lower value of 6MWD is within 20% of the higher value of 6MWD
1.Subject has received any investigational therapy or pharmacological treatment for Pompe disease, other than alglucosidase alfa, within 30 days or 5 half-lives of the therapy or treatment, whichever is longer, before Day 1 or is anticipated to do so during the study.
2.Subject has received gene therapy for Pompe disease.
3.Subject is taking any of the following prohibited medications within 30 days before Day 1:
-miglitol (eg, Glyset)
-miglustat (eg, Zavesca)
-acarbose (eg, Precose or Glucobay)
