VIMIZIM

ELOSULFASE ALFA
Approved 2014-02-14

VIMIZIM (elosulfase alfa) is a hydrolytic lysosomal glycosaminoglycan-specific enzyme indicated for the treatment of patients with Mucopolysaccharidosis type IVA, also known as Morquio A syndrome. This condition is a lysosomal storage disorder caused by a deficiency in the specific enzyme required for the catabolism of glycosaminoglycans. The therapy provides an exogenous source of the missing enzyme to address the widespread cellular, tissue, and organ dysfunction associated with the disease.

How VIMIZIM Works

VIMIZIM provides the exogenous enzyme N-acetylgalactosamine-6-sulfatase to replace the activity missing in patients with Morquio A syndrome. The enzyme is internalized into cellular lysosomes via mannose-6-phosphate receptors, where it facilitates the catabolism of accumulated glycosaminoglycan substrates, specifically keratan sulfate and chondroitin-6-sulfate. By increasing the breakdown of these substances, the drug reduces lysosomal storage and addresses the underlying metabolic deficiency.
