Aldurazyme (LARONIDASE)

BioMarin · FDA-approved approved Enzyme Quality 50/100

Aldurazyme breaks down abnormal sugar molecules in the body to treat Mucopolysaccharidosis I.

Aldurazyme (Laronidase) is a hydrolytic lysosomal glycosaminoglycan-specific enzyme developed by Biogen (not Biomarin, though it was acquired by them) and approved by the FDA in 2003. It is a small molecule modality used to treat Mucopolysaccharidosis I (MPS-I), a rare genetic disorder. The commercial status of Aldurazyme is patented, and it is currently owned by Biogen. Key safety considerations include potential infusion reactions and the risk of anaphylaxis. Aldurazyme works by breaking down abnormal sugar molecules in the body.

Mechanism of action

Mucopolysaccharide storage disorders are caused by the deficiency of specific lysosomal enzymes required for the catabolism of glycosaminoglycans (GAG). Mucopolysaccharidosis (MPS I) is characterized by the deficiency of -L-iduronidase, lysosomal hydrolase which catalyzes the hydrolysis of terminal -L-iduronic acid residues of dermatan sulfate and heparan sulfate. Reduced or absent -L-iduronidase activity results in the accumulation of the GAG substrates, dermatan sulfate and heparan sulfate, throughout the body and leads to widespread cellular, tissue, and organ dysfunction.The rationale of ALDURAZYME therapy in MPS is to provide exogenous enzyme for uptake into lysosomes and increase the catabolism of GAG. ALDURAZYME uptake by cells into lysosomes is most likely mediated by the mannose-6-phosphate-terminated oligosaccharide chains of laronidase binding to specific mannose-6-phosphate receptors. Because many proteins in the blood are restricted from entry int
