On Aug. 6, 2021, the U.S. Food and Drug Administration approved Genzyme’s Nexviazyme (avalglucosidase alfa-ngpt) for intravenous infusion to treat patients 1 year of age and older with late-onset Pompe disease.

Patients with Pompe disease have an enzyme deficiency that leads to the accumulation of a complex sugar, called glycogen, in skeletal and heart muscles, which cause muscle weakness and premature death from respiratory or heart failure.
