Who holds the patent for Agalsidase Alfa?

Introduction to Agalsidase Alfa 
Agalsidase alfa is a recombinant form of the lysosomal enzyme α‐galactosidase A designed for enzyme replacement therapy (ERT) in the treatment of Fabry disease. Fabry disease is a rare, X‐linked lysosomal storage disorder in which the deficiency of α‐galactosidase A leads to the accumulation of glycosphingolipids, specifically globotriaosylceramide (GL-3), in various tissues. Agalsidase alfa works by providing a functional enzyme that can help clear the accumulated substrates and mitigate the progressive, multisystemic clinical manifestations of Fabry disease. The enzyme is produced using advanced biotechnological methods and is formulated for intravenous infusion, thereby emphasizing its role as an essential biopharmaceutical treatment in this area.

Therapeutic Use and Indications 
The primary indication for agalsidase alfa is the long-term treatment of Fabry disease. Its administration is associated with improvements in multiple organ systems. Clinical studies report that long-term treatment with agalsidase alfa can lead to significant and sustained clinical benefits, such as improved kidney function, stabilization or reduction of left ventricular mass, and attenuation of neuropathic pain. Given that Fabry disease involves a spectrum of symptoms—from acroparesthesias in childhood to significant renal, cardiac, and cerebrovascular involvement in adulthood—the therapeutic use of agalsidase alfa is a cornerstone in managing this progressive condition. Its clinical development, along with postmarketing surveillance, has established its role as an efficacious and well-tolerated enzyme replacement therapy in both male and female patients, and even in pediatric populations.
