ADME/Pharmacokinetics |
Absorption, Distribution and Excretion
A dose of agalsidase alfa in non end stage renal disease patients reaches a Cmax of 3710 ± 855 U/mL with an AUC of 256,958 ± 63,499 min\*U/mL. After nonspecific proteolysis, the amino acids from protein drugs are reused for protein synthesis or further broken down and eliminated by the kidneys. The volume of distribution at steady state in non end stage renal disease patients was approximately 17% of body weight regardless of sex. The clearance for doses of 0.007-0.2 mg/kg were 2.66 mL/min/kg for males and 2.10 mL/min/kg for females. Metabolism / Metabolites Data regarding the metabolism of agalsidase alfa is not readily available. However, protein drugs are expected to be degraded by proteases and other catalytic enzymes to smaller peptides and amino acids. Biological Half-Life The elimination half life was 108 ± 17 minutes for males and 89 ± 28 minutes for females. |

Toxicity/Toxicokinetics |
Effects During Pregnancy and Lactation
◉ Summary of Use during Lactation Because there is no published experience with eliglustat during breastfeeding, an alternate drug may be preferred, especially while nursing a newborn or preterm infant. ◉ Effects in Breastfed Infants Relevant published information was not found as of the revision date. ◉ Effects on Lactation and Breastmilk Relevant published information was not found as of the revision date. Protein Binding Agalsidase alfa is not expected to be protein bound in circulation. |

Additional Infomation |
Eliglustat tartrate is a tartrate that is the hemitartrate salt of eliglustat. A ceramide glucosyltransferase inhibitor used (as its tartrate salt) for treatment of Gaucher's disease. It has a role as an EC 2.4.1.80 (ceramide glucosyltransferase) inhibitor. It contains an eliglustat(1+).
Agalsidase alfa is a recombinant human α-galactosidase A similar to [agalsidase beta]. 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 alfa was granted EMA approval on 3 August 2001. See also: Eliglustat (has active moiety); Agalsidase Beta (annotation moved to). Drug Indication Agalsidase alfa is indicated in the treatment of Fabry disease. Replagal is indicated for long-term enzyme-replacement therapy in patients with a confirmed diagnosis of Fabry disease (α-galactosidase-A deficiency). Mechanism of Action α-galactosidase A is uptaken by cells via the mannose 6 phosphate receptor. Agalsidase alfa hydrolyzes globotriaosylceramide and other glycosphingolipids that would normally be hydrolyzed by endogenous α-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. Pharmacodynamics Agalsidase alfa is a recombinant human α-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. |
