Purpose: Outcomes in patients with Fabry disease receiving migalastat during the phase 3 FACETS trial (NCT00925301) were evaluated by phenotype. Methods: Data were evaluated in two subgroups of patients with migalastat-amenable GLA variants: classic phenotype (n = 14; males with residual peripheral blood mononuclear cell alpha-galactosidase A <3% normal and multiorgan system involvement) and other patients (n = 36; males not meeting classic phenotype criteria and all females). Endpoints included estimated glomerular filtration rate (eGFR), left ventricular mass index (LVMi), Gastrointestinal Symptoms Rating Scale diarrhea subscale (GSRS-D), renal peritubular capillary (PTC) globotriaosylceramide (GL-3) inclusions, and plasma globotriaosylsphingosine (lyso-Gb(3)). Results: Baseline measures in the classic phenotype patients suggested a more severe phenotype. At month 24, mean (SD) annualized change in eGFR(CKD-EPI) with migalastat was -0.3 (3.76) mL/min/1.73 m(2) in the classic phenotype subgroup; changes in LVMi, GSRS-D, and lyso-Gb(3) were -16.7 (18.64) g/m(2), -0.9 (1.66), and -36.8 (35.78) nmol/L, respectively. At month 6, mean PTC GL-3 inclusions decreased with migalastat (-0.8) and increased with placebo (0.3); switching from placebo to migalastat, PTC inclusions decreased by -0.7. Numerically smaller changes in these endpoints were observed in the other patients. Conclusion: Migalastat provided clinical benefit to patients with Fabry disease and amenable variants, regardless of disease severity.
