- Determination of pharmacokinetic parameters of αGAL in breast milk: Cmax [ Time Frame: Month 1, 3, and 6 ]Maximum concentration (Cmax) of αGAL in breast milk
- Determination of pharmacokinetic parameters of αGAL in breast milk: AUC0-2h [ Time Frame: Month 1, 3, and 6 ]Area under the plasma αGAL concentration-time curve (AUC) from 0 to 2 hours post end of infusion (AUC0-2)
- Determination of pharmacokinetic parameters of αGAL in breast milk: lactation clearance [ Time Frame: Month 1, 3, and 6 ]Lactation clearance will be estimated as the amount of αGAL excreted over the sampling period divided by the AUC during the sampling period.
- Volume of breast milk [ Time Frame: Baseline, Month 2, 6, and 12 ]Determination of volume of breast milk sample
- Fat content of breast milk [ Time Frame: Baseline, Months 2, 6, and 12 ]Determination of total fat content in breast milk sample
- Protein content of breast milk [ Time Frame: Baseline, Months 2, 6, and 12 ]Determination of total protein content in breast milk sample
- Growth response of infants [ Time Frame: Months 1, 2, 3, 6, 12, 18 and Month 24 ]Absolute change in growth of infants
- Development response of infants [ Time Frame: Months 1, 2, 3, 6, 12, 18 and Month 24 ]Absolute change in weight of infants
- Immunologic response of infants - IgG [ Time Frame: Baseline, Months 2, 6, and 12 ]Formation or presence of immunoglobulin G (IgG) antibodies to recombinant human α galactosidase A (r-hαGAL)
- Immunologic response of infants - IgM [ Time Frame: Baseline, Months 2, 6, and 12 ]Formation or presence of immunoglobulin M (IgM) antibodies to recombinant human α galactosidase A (r-hαGAL)
