Brand Names: Vimizim

Generic Name: elosulfase alfa

What is elosulfase alfa (Vimizim)?

Elosulfase alfa contains an enzyme that occurs naturally in the body in healthy people. Some people lack this enzyme because of a genetic disorder. Elosulfase alfa helps replace this missing enzyme in such people.

Elosulfase alfa is used to treat some of the symptoms of a genetic condition called mucopolysaccharidosis (MYOO-koe-pol-ee-SAK-a-rye-DOE-sis) IV (4) type A, or MPS IV A, also called Morquio A syndrome.

MPS IVA is a metabolic disorder in which the body lacks the enzyme needed to break down certain natural substances. These substances can build up in the body, causing enlarged organs, abnormal bone structure, changes in facial features, breathing problems, heart problems, vision or hearing loss, and changes in mental or physical abilities.

Elosulfase alfa may improve walking and stair-climbing ability in people with this condition. However, this medication is not a cure for MPS IVA.

Elosulfase alfa may also be used for purposes not listed in this medication guide.
