BioMarin Submits VIMIZIM™ (elosulfase alfa) NDS to Health Canada for the Treatment of Morquio A Syndrome Under Priority Review Status

Approval would deliver first treatment for Canadians living with ultra-rare, genetic metabolic disorder

TORONTO, Dec. 4, 2013 /CNW/ - BioMarin Pharmaceutical Inc. (Nasdaq:BMRN) announced today that it submitted a New Drug Submission (NDS) for VIMIZIM™ (elosulfase alfa) under Priority Review status. VIMIZIM is an investigational enzyme replacement therapy for the treatment of patients with the lysosomal storage disorder Morquio A syndrome, also called Mucopolysaccharidosis Type IVA (MPS IVA). Approval of VIMIZIM would make it the first available drug treatment option for Canadians living with this rare genetic metabolic disorder.

"Morquio A is an extremely rare disease that substantially limits both the quality and length of life for those affected by it. There is no cure, and current available treatments are primarily symptomatic," said Dr. Julian Raiman, a leading pediatric metabolic geneticist based in Toronto. "The potential approval of VIMIZIM would fill a critical unmet need for patients living with this severely debilitating, life-limiting and progressive disease."

Health Canada designates Priority Review to drugs that offer major advances in treatment or provide a treatment where no adequate therapy exists. Priority is intended to accelerate the regulatory review.

"Every day, Canadians living with Morquio A face seemingly insurmountable challenges. We are encouraged that children who are born with this disorder could soon have a drug therapy option that treats the root cause of the disease," said Kirsten Harkins, Executive Director, The Canadian Society for Mucopolysaccharide and Related Diseases Inc. (The Canadian MPS Society).

"BioMarin has submitted the NDS to Health Canada based on the results from our Phase 3 pivotal study, which we believe demonstrates that VIMIZIM offers a substantial benefit to patients with Morquio A," said Hank Fuchs, M.D., Chief Medical Officer of BioMarin. "With this application, BioMarin continues in its long-standing tradition of advancing important therapies for those who are most in need."

About VIMIZIM
VIMIZIM (elosufase alfa) is an investigational treatment for patients with Morquio A syndrome, or mucopolysaccharidosis IVA (MPS IVA), which is currently under review by the FDA. VIMIZIM is the first and only enzyme replacement therapy (ERT) designed to target the underlying cause of Morquio A Syndrome - a deficiency in the enzyme N-acetylgalactosamine-6 sulfatase (GALNS). Infused enzyme replacement therapy with VIMIZIM replaces deficient GALNS activity to minimize progressive multi-systemic manifestations. Morquio A syndrome is a rare, severely debilitating and progressive disease that currently has no standard accepted treatment other than supportive care.

About Morquio A Syndrome
Morquio A Syndrome, or mucopolysaccharidosis IVA (MPS IVA), is a disease in which people are missing an enzyme that is essential in the breakdown and removal of the mucopolysaccharides called keratan sulfate. The incompletely broken down mucopolysaccharides remain stored in cells in the body causing progressive damage. This excessive storage causes a systemic skeletal dysplasia, short stature, and joint abnormalities, which limit mobility and endurance. Malformation of the chest impairs respiratory function, and looseness of joints in the neck cause spinal instability and potentially spinal cord compression. Other symptoms may include hearing loss, corneal clouding, and heart disease. Initial symptoms often become evident in the first five years of life. The disease substantially limits both the quality and length of life of those affected.

The rate of incidence of Morquio A syndrome is as yet unconfirmed and varies among different populations, and estimates vary between 1 in 200,000 live births and 1 in 450,000 live births. The estimated prevalence is approximately 3,000 patients in the developed world.
