ClinConnect Summary

This open-label study was conducted in 2 stages (Stage 1, Stage 2). Stage 1 included migalastat 150 mg; Stage 2 included migalastat 450 mg. Each dose of migalastat was selected to evaluate interaction with each of 3 doses of recombinant agalsidase: 0.5 mg/kilogram (kg) agalsidase beta; 1.0 mg/kg agalsidase beta; 0.2 mg/kg agalsidase alfa.

Migalastat was administered orally. Agalsidase alfa was administered as a 40-minute intravenous (IV) infusion and agalsidase beta was administered as a 2-hour (hr) IV infusion.

Stage 1 consisted of 3 treatment periods with 14 days intervening between eac...
