What is enzyme replacement therapy for Fabry disease?

In patients with Fabry disease, deficient enzymatic activity of alpha-galactosidase A (α-Gal A) leads to an accumulation of the glycosphingolipids globotriaosylceramide (Gb3) and globotriaosylsphingosine (lyso-Gb3) within almost all cell types and various organs.1-3 Enzyme replacement therapy introduces recombinant enzyme α-Gal A into lysosomes to help address the underlying enzyme deficiency and restore breakdown of accumulated Gb3 in patients with Fabry disease, in addition to the associated multisystemic disease manifestations (Figure 1).Two intravenous enzyme replacement therapies are available for patients with Fabry disease: agalsidase alfa and agalsidase beta.5,6 The availability of treatments differs between countries. For further information, please consult your local prescribing information.
