Agalsidase beta is a recombinant human -galactosidase A similar to [agalsidase alfa]. While patients generally do not experience a clinically significant difference in outcomes between the two drugs, some patients may experience greater benefit with agalsidase beta. Use of agalsidase beta has decreased in Europe, in favor of agalsidase alfa, after a contamination event in 2009. Agalsidase beta was granted FDA approval on 24 April 2003.

4 Drug and Medication Information
4.1 Drug Indication

Agalsidase beta is indicated in the treatment of Fabry disease.


FDA Label


Cerdelga is indicated for the long-term treatment of adult patients with Gaucher disease type 1 (GD1), who are CYP2D6 poor metabolisers (PMs), intermediate metabolisers (IMs) or extensive metabolisers (EMs).


Treatment of Gaucher disease Type 1 and Type 3, Treatment of Gaucher disease Type 2


Fabrazyme is indicated for long-term enzyme replacement therapy in patients with a confirmed diagnosis of Fabry disease (-galactosidase-A deficiency).


5 Pharmacology and Biochemistry
5.1 Pharmacology

Agalsidase beta is a recombinant human -galactosidase A used as enzyme replacement therapy in the treatment of Fabry disease. It has a long duration of action and a wide therapeutic index. Patients should be counselled regarding the risk of infusion related reactions and hypersensitivity.


5.2 MeSH Pharmacological Classification

Enzyme Inhibitors

Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction. (See all compounds classified as Enzyme Inhibitors.)


5.3 FDA Pharmacological Classification

5.5 Absorption, Distribution and Excretion

Absorption

A 1 mg/kg dose of agalsidase beta with a mean infusion length of 115 minutes reaches a Cmax 5.0 1.1 g/mL with an AUC of 496 137 g\*min/mL.


Route of Elimination

After nonspecific proteolysis, the amino acids from protein drugs are reused for protein synthesis or further broken down and eliminated by the kidneys.


Volume of Distribution

A 1 mg/kg dose of agalsidase beta with a mean infusion length of 115 minutes has a VSS of 112 13 mL/kg.


Clearance

A 1 mg/kg dose of agalsidase beta with a mean infusion length of 115 minutes has a clearance of 2.1 0.7 mL/min/kg.


5.6 Metabolism/Metabolites

Data regarding the metabolism of agalsidase beta is not readily available. However, protein drugs are expected to be degraded by proteases and other catalytic enzymes to smaller peptides and amino acids.


5.7 Biological Half-Life

agalsidase beta has a half like of 67 12 min for a 1 mg/kg dose with a mean infusion length of 115 minutes.


5.8 Mechanism of Action

-galactosidase A is uptaken by cells via the mannose 6 phosphate receptor. Agalsidase beta hydrolyzes globotriaosylceramide and other glycosphingolipids that would normally be hydrolyzed by endogenous -galactosidase A. Preventing the accumulation of glycosphingolipids prevents or reduces the severity of manifestations of Fabry disease such as renal failure, cardiomyopathy, or cerebrovascular events.
