Enzyme replacement therapy

Enzyme replacement therapy (ERT) uses an intravenous solution (IV) to replace a deficient or missing enzyme in the body. ERT does not cure the disease but slows its progress by increasing the amount of missing enzyme in the body.

Enzyme replacement therapy is currently available for five MPS disorders MPS I, MPS II, MPS IVA, MPS VI and MPS VII.


Aldurazyme™ (laronidase), administered once weekly, is approved in more than 60 countries worldwide, including the United States and across Europe for long-term enzyme replacement therapy in patients with a confirmed diagnosis of MPS I, to treat the non-neurological manifestations of the disease. Aldurazyme was developed by BioMarin and SanofiGenzyme under a joint venture agreement that assigns commercial manufacturing responsibilities to BioMarin, and worldwide sales and marketing responsibilities to SanofiGenzyme.

Visit or contact SanofiGenzyme at 800-745-4447 for more information.
