Why am I being given Nexviazyme?

Nexviazyme contains the active ingredient avalglucosidase alfa. Avalglucosidase alfa is an artificial enzyme that can replace the natural enzyme that is lacking in Pompe disease.
Nexviazyme is used to treat Pompe disease. Pompe disease is a rare genetic disease in which the level of an enzyme called acid alfa-glucosidase is missing or is lower than in healthy individuals. This enzyme helps the body control levels of glycogen (a type of carbohydrate).
