Shire Provides Update on U.S. Marketing Application of ELAPRASE^TM

Cambridge, MA US and Basingstoke, UK – May 17, 2006 -- Shire plc (LSE: SHP, NASDAQ: SHPGY, TSX: SHQ) announces that the Food and Drug Administration (FDA) has extended by 90 days the review period for the biologics license application (BLA) for ELAPRASE^TM (idursulfase). This extension will allow the FDA additional time to review data and analyses they recently requested during label discussions. Therefore, the FDA advised us at close of US business yesterday that the new action date for the application is August 24, 2006.

“Shire will continue to work closely with the FDA during this brief extension of the ELAPRASE BLA review and through this cooperative effort we expect that ELAPRASE will be approved and launched by the third quarter 2006,” said Matthew Emmens, Chief Executive Officer of Shire. "There is no existing treatment for patients with Hunter syndrome and Shire is confident that the FDA recognizes the importance of making ELAPRASE available to these patients."

The US BLA for ELAPRASE was submitted in November 2005 and was granted priority review, requiring the FDA to take action within six months. A marketing authorization application for ELAPRASE has been submitted to the European Medicines Agency, and Shire expects a response on that application before the end of the year.

ELAPRASE has been developed for the treatment of Hunter syndrome, a serious genetic disorder, mainly affecting males, that interferes with the body’s ability to break down and recycle specific chemicals called mucopolysaccharides, also known as glycosaminoglycans or GAG. Hunter syndrome is one of several related lysosomal storage diseases.

SHIRE PLC

Shire’s strategic goal is to become the leading specialty pharmaceutical company that focuses on meeting the needs of the specialist physician. Shire focuses its business on central nervous system, gastrointestinal, general products and human genetic therapies. The structure is sufficiently flexible to allow Shire to target new therapeutic areas to the extent opportunities arise through acquisitions. Shire believes that a carefully selected portfolio of products with a strategically aligned and relatively small-scale sales force will deliver strong results.

Shire’s focused strategy is to develop and market products for specialty physicians. Shire’s in-licensing, merger and acquisition efforts are focused on products in niche markets with strong intellectual property protection either in the US or Europe.
