MEPSEVII
Mepsevii (vestronidase alfa-vjbk) is a recombinant human lysosomal beta glucuronidase indicated for the treatment of Mucopolysaccharidosis VII, also known as Sly syndrome. The therapy is approved for use in both pediatric and adult patients to address the underlying enzyme deficiency associated with the disorder. However, the effect of this treatment on the central nervous system manifestations of the disease has not been determined.
How MEPSEVII Works
Mucopolysaccharidosis VII is caused by a deficiency of the enzyme beta glucuronidase (GUS), which results in the accumulation of glycosaminoglycans (GAGs) and subsequent multisystem tissue damage. Vestronidase alfa-vjbk provides an exogenous source of the GUS enzyme that is internalized into cellular lysosomes via mannose-6-phosphate receptors on the cell surface. Once inside the lysosomes, the enzyme facilitates the catabolism of accumulated GAGs in affected tissues.
