Drug Names(s): agalsidase alfa


Replagal (agalsidase alfa) is an enzyme replacement therapy indicated for use in the treatment of Fabry disease. Patients with Fabry disease have a deficiency of the enzyme alpha-galactosidase A. This enzyme deficiency results in an accumulation of a toxic lipid called globotriaosylceramide or Gb3 in various organs of the body, including the nervous system, kidneys, and heart. Administration of Replagal is an attempt to restore normal levels of enzyme activity and alleviate some of the effects of the disease. As Replagal is an enzyme replacement therapy, it is a protein drug. Specifically, Replagal contains the human enzyme a-galactosidase A produced by genetic engineering in a continuous human cell line.
