Shire Announces Regulatory Filings in US and EU for New Manufacturing Facility

LEXINGTON, Massachusetts, November 22, 2011 -

Approval Will Add Substantial Manufacturing Capacity for Rare Disease Products

Shire plc (LSE: SHP, NASDAQ: SHPGY), the global specialty biopharmaceutical company, today announced that it has submitted regulatory filings with both the European Medicines Agency (EMA) and the U.S. Food and Drug Administration (FDA) for the production of VPRIV^® (velaglucerase alfa) in its state-of-the-art manufacturing facility at 400 Shire Way in Lexington, Massachusetts. Subject to regulatory approval, which is anticipated in early 2012, Shire expects the new plant to significantly increase manufacturing capacity and allow for increased global supply of VPRIV.  These approvals will also make available further capacity for the manufacture of Replagal^® (agalsidase alfa) at Shire’s Alewife facility, where both VPRIV and Replagal are currently manufactured.

“Shire remains committed to meeting the unique needs of patients living with rare diseases,” said Bill Ciambrone, Senior Vice President, Technical Operations, Shire HGT. “Accelerating the completion of our new manufacturing facility in Lexington will enable us to provide substantial additional capacity for VPRIV less than two years after launch. Once approved, this new facility will give us greater flexibility to meet the global demand for VPRIV as well as some of our other products for rare diseases.”

Currently there are approximately 1,200 patients receiving VPRIV and over 2,800 patients receiving Replagal worldwide. Shire is committed to provide current patients with uninterrupted long-term access to treatment at the dose and frequency prescribed by their physician.

About VPRIV (velaglucerase alfa)

On February 26, 2010, VPRIV was approved by the FDA as a hydrolytic lysosomal glucocerebroside-specific enzyme indicated for long-term enzyme replacement therapy for adult and pediatric patients with type 1 Gaucher disease. On August 26, 2010, the European Commission granted marketing authorization for VPRIV for the long-term treatment of type 1 Gaucher disease, making it available in 30 countries across Europe.  VPRIV is currently approved in 38 countries world wide.

VPRIV is for patients who are treatment-naïve as well as patients who have previously been treated with imiglucerase.

About REPLAGAL (agalsidase alfa)

Replagal is a form of the human enzyme alfa-galactosidase A (α-Gal A) manufactured in a human cell line by gene activation. 2011 marks the 15th year of clinical experience with Replagal, which is now approved in 46 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 that is indicated for the long-term treatment of patients with a confirmed diagnosis of Fabry disease (α-Gal A deficiency).

VPRIV Important Safety Information

Infusion-related reactions were the most commonly observed adverse reactions in patients treated with VPRIV in clinical studies. The most commonly observed symptoms of infusion-related reactions were: headache, dizziness, low or high blood pressure, nausea, tiredness and weakness, and fever.  Generally the infusion-related reactions were mild and, in treatment-naïve patients, onset occurred mostly during the first 6 months of treatment and tended to occur less frequently with time.
