MYOZYME (alglucosidase alfa)

Rare Disease Approved 2006-04-28

MYOZYME is indicated for the treatment of Pompe Disease.

Source: FDA Label • Sanofi • Hydrolytic Lysosomal Glycogen-specific Enzyme

How MYOZYME Works

Alglucosidase alfa provides an exogenous source of the enzyme GAA, which is deficient in patients with Pompe disease. The drug binds to mannose-6-phosphate receptors on the cell surface and is transported into lysosomes, where it undergoes proteolytic cleavage to achieve full enzymatic activity. Once activated, the enzyme cleaves accumulated glycogen, facilitating the proper metabolism of glycogen within the cells.
