Healthcare Industry News: enzyme replacement therapy
News Release - February 24, 2010
Shire Provides Update on Biologics License Application (BLA) Filing for REPLAGAL(R) (agalsidase alfa) With the U.S. Food and Drug Administration (FDA)CAMBRIDGE, Massachusetts, February 24, 2010 (Healthcare Sales & Marketing Network) -- Shire plc (LSE: SHP, NASDAQ: SHPGY), the global specialty biopharmaceutical company, announces it has received Fast Track designation from the FDA for REPLAGAL(R) (agalsidase alfa), its enzyme replacement therapy for Fabry disease.
Shire filed a BLA for REPLAGAL in December 2009. The FDA requested additional human pharmacokinetic data to confirm comparability between product that was manufactured in roller bottles, and that which is manufactured in bioreactors. Product made by the bioreactor process is already approved for commercial use in the European Union as well as a number of other countries.
As a result of this request, Shire withdrew its December BLA filing, and, at the suggestion of the FDA, requested and received Fast Track designation. Shire will immediately initiate the rolling submission of the REPLAGAL BLA, and will submit the requested pharmacokinetic data around mid-year.
Fast Track designation is an FDA-approved process that facilitates the development and expedites the review of drugs to treat serious diseases and fill an unmet medical need with the goal of getting important new treatments to patients earlier. This process allows a company to file the sections of the BLA as they become available instead of filing all the sections at once. It also enables the agency to commence its review and proceed on a rolling basis as the additional sections are completed and submitted for review.
"We will continue to work closely with the FDA in the coming months on the rolling BLA submission for REPLAGAL, "said Sylvie Gregoire, President, Shire Human Genetic Therapies. "We remain committed to continuing to provide Fabry patients in the United States with REPLAGAL under the treatment protocol."
REPLAGAL is currently approved for the treatment of Fabry disease in 45 countries and has been available to U.S. patients since December 2009 under an FDA-approved treatment protocol filed at the request of FDA. The REPLAGAL early access program was put in place as a result of the supply disruption of the only currently marketed treatment for Fabry disease in the U.S.
Financial guidance for 2010 provided in Shire's year-end results press release and earnings call on February 19, 2010 remains unchanged.
About REPLAGAL(R) (agalsidase alfa)
REPLAGAL is a human form of enzyme alpha-galactosidase A (a-Gal A) manufactured in a human cell line by gene activation. REPLAGAL is approved in 45 countries worldwide. REPLAGAL is not currently approved for commercial sale in the U.S.
REPLAGAL is the only human-cell-line-derived form of enzyme replacement therapy (ERT) that is indicated for the long-term treatment of patients with a confirmed diagnosis of Fabry disease ([alpha]-galactosidase A deficiency).
About Fabry disease
Fabry disease is a lysosomal storage disorder (LSD) that interferes with the body's ability to break down a specific fatty substance ( globotriaosylceramide or Gb3) which accumulates within the body due to deficiency of a specific enzyme ([alpha]-galactosidase A).
Fabry disease affects both males and females and can present with a number of signs or symptoms of variable degree, such as cardiovascular and/or renal dysfunction, intense or burning pain, heat intolerance, skin lesions, gastrointestinal complaints, hearing loss, and ocular problems.
Lifespan is typically reduced in patients with Fabry disease by approximately 20 years in men and 15 years in women, compared with the general population.1,2 The principal causes of death are renal failure, cardiomyopathy and cerebrovascular events (e.g. stroke).3
Fabry disease affects an estimated 8,000 to 10,000 people worldwide.

Notes to editors
Shire's strategic goal is to become the leading specialty biopharmaceutical company that focuses on meeting the needs of the specialist physician. Shire focuses its business on attention deficit hyperactivity disorder (ADHD), human genetic therapies (HGT) and gastrointestinal (GI) diseases as well as opportunities in other therapeutic areas to the extent they arise through acquisitions. Shire's in-licensing, merger and acquisition efforts are focused on products in specialist markets with strong intellectual property protection and global rights. Shire believes that a carefully selected and balanced portfolio of products with strategically aligned and relatively small-scale sales forces will deliver strong results.
