This was a Phase 2, open-label study in male participants with Fabry disease. The study consisted of a 4-week screening period, during which participants' galactosidase (GLA) genotype was assessed for α-galactosidase A (α-Gal A) activity in response to migalastat. Participants were required to have α-Gal A activity responsive to migalastat. The study consisted of a 24-week treatment period, followed by an optional 24-week extension period. Participants received migalastat once every other day (QOD) for 24 weeks during the treatment period and the optional 24-week extension for a total treatment duration of up to 48 weeks.
Study to evaluate the safety, tolerability, and pharmacodynamics of migalastat hydrochloride (HCl) (migalastat) in participants with Fabry disease.
