Alglucosidase alfa is an enzyme replacement therapy orphan drug for treatment of Pompe disease (Glycogen storage disease type II), a rare lysosomal storage disorder (LSD). It is postulated that alglucosidase alfa will restore lysosomal GAA activity resulting in stabilisation or restoration of cardiac and skeletal muscle function (including respiratory muscles). Due to the bloodbrain barrier effect and the enzyme’s size, uptake of alglucosidase alfa in the central nervous system is unlikely.
