- Primary Outcome Measures
Name Time Method The primary objective of this study is to characterize the pharmacokinetics of alglucosidase alfa manufactured at the 4000 L scale in patients ranging from 8 to 18 years of age who have a confirmed diagnosis of Pompe disease.Timepoint: �Maximum observed concentration (Cmax) [Time Frame: Day 1,wk12,wk26] <br/ ><br>�Actual sampling time to reach maximum observed concentration (Tmax)[Time Frame:Day1,Wk12,Wk26] <br/ ><br>�Area under the concentration-time curve from 0 to the time of the last quantifiable concentration (AUC last) <br/ ><br>�Area under the concentration-time curve from time 0 and extrapolated to infinite time(AUC inf) <br/ ><br>�Terminal elimination half-life(T1/2) <br/ ><br>�Total systemic clearance (CL) <br/ ><br>�Volume of distribution (Vd)
- Secondary Outcome Measures
Name Time Method A secondary objective of this study is to evaluate the impact of immunogenicity (anti-recombinant human acid �±-glucosidase [rhGAA] immunoglobulin G [IgG] titers and inhibitory/neutralizing antibodies) on the pharmacokinetics of alglucosidase alfa.Timepoint: â�¢Impact of anti-rhGAA IgG antibodies on pharmacokinetic (PK) profile as measured by change in assessed PK parameters including clearance [ Time Frame: Day 1, Week 12, Week 26 ] <br/ ><br>â�¢Impact of inhibitory/neutralizing antibodies on pharmacokinetic (PK) profile as measured by change in assessed PK parameters including clearance [ Time Frame: Day 1, Week 12, Week 26 ]
