Impact of the organic cation transporter 2 inhibitor cimetidine on the single-dose pharmacokinetics of the glucosylceramide synthase inhibitor lucerastat in healthy subjects

Abstract
Lucerastat is an orally available glucosylceramide synthase inhibitor with a potential to provide substrate reduction therapy for Fabry patients independent of their α-galactosidase A genotype. In humans, lucerastat is mainly eliminated as unchanged parent compound through renal excretion both by active secretion and passive filtration. In vitro studies indicated that lucerastat is a substrate of human organic cation transporter 2 (OCT2) mainly expressed in the kidney.
