Shire plc: Excellent Third Quarter With Execution Plan On Track - Upgrading 2006 Revenue Guidance

BASINGSTOKE, England and PHILADELPHIA, Pennsylvania, October 27 /PRNewswire-FirstCall/ -- Shire plc announces results for the third quarter 2006.

Matthew Emmens, Chief Executive Officer, commented:

“It’s been an excellent quarter across all areas of our business. We have continued to make good progress. Our execution plan is well on track and therefore we are upgrading our revenue guidance for the full year.

“Our leading Attention Deficit Hyperactivity Disorder (ADHD) franchise continues to grow, capturing over 29% of the US market in Q3 2006 following the success of our newly launched patch DAYTRANA(TM) and the continued strong performance of ADDERALL XR(R). We are well positioned to build on our strengths - this month, the Food and Drug Administration (FDA) issued an approvable letter for our latest ADHD treatment, NRP104 that we expect to launch in Q2 2007. We filed for US regulatory approval of SPD465 and SPD503, demonstrating our commitment to provide patients and physicians with the broadest range of ADHD treatment choices. In addition, in August, we settled all pending litigation with Barr Laboratories Inc. (Barr) in connection with ADDERALL XR.

“We are also making good progress in other areas of our portfolio. In July, we received approval for ELAPRASE(TM) in the US, for the treatment of Hunter syndrome and last week the Committee for Medicinal Products for Human Use (CHMP) recommended approval in the EU. We already have 127 patients worldwide on this treatment.

“We expect a response from the European Authorities for our ulcerative colitis product, MESAVANCE(TM) by the end of this year and from the FDA in the US in January; this product remains on track for launch in Q1 2007.

“Earlier this year we gave revenue guidance of low double digit growth. As we approach the year end we now anticipate this will be in the range of 12-14%. Total costs are expected to be in line with previous guidance. As 2007 approaches, we remain focused on implementing our strategy and we are on track to deliver several more new products to market.”

Q3 2006 Financial highlights

- Product sales of US$386.2 million - up 25% versus Q3 2005 (19% growth YTD).

- Total revenues of US$449.4 million - up 19% versus Q3 2005 (15% growth in YTD).

Product highlights and recent events

NRP104 - ADHD

- Shire’s collaborative partner, New River Pharmaceuticals Inc. (New River), received an approvable letter from the FDA for NRP104 for the treatment of pediatric ADHD. No additional studies were requested by the FDA as a condition for full approval. Shire and New River are preparing for a product launch in Q2 2007, pending final labeling and scheduling discussions.

DAYTRANA - ADHD

- DAYTRANA captured 1.7% of the total US ADHD market after only three months.

ELAPRASE - Hunter syndrome.

- On October 19, the CHMP of the European Medicines Agency (EMEA) issued a positive opinion recommending approval of ELAPRASE for the long-term treatment of patients with Hunter syndrome. The EU Marketing Authorisation is expected early in 2007 and will result in unified labeling that will be valid in the 25 current EU member states as well as in Iceland and Norway.

- The FDA granted approval for ELAPRASE in July this year and to date there are 67 patients on this treatment in the US. Early access has been granted to patients with Hunter syndrome in a number of European countries including Italy, Germany, Spain, France, Sweden, Norway and Denmark. Demand from patients’ families and clinicians has been high and 60 patients have already been infused with the treatment in these countries.

REPLAGAL(R) - Fabry disease

- In September 2006, Shire agreed to partner with the Canadian government to support a Fabry post-marketing study that will monitor all Fabry patients. As a result of the agreement, Fabry patients currently or previously on enzyme replacement therapy and new Fabry patients who meet the guidelines will be eligible for funded enzyme replacement therapy.

- During the quarter, the European Commission approved a variation to update sections of the product information to include data on the treatment of children with REPLAGAL. A beneficial effect of treatment was seen in a small number of children aged 7-18 years with no unexpected safety issues.

FOSRENOL(R) - Hyperphosphatemia

- On October 18, Health Canada granted a marketing license application for FOSRENOL. Launch is now planned for Q2 2007.

- The roll-out of FOSRENOL continues in the European markets. Earlier this year, the product was launched both in Sweden and Ireland. According to wholesaler data, FOSRENOL captured 15% of the Swedish and 10% of the Irish total phosphate binder End Stage Renal Disease (ESRD) market.

Pipeline Highlights

SPD465 - ADHD

- A new drug application (NDA) was submitted to the FDA for SPD465 on July 21, for the treatment of ADHD in the adult population. The Prescription Drug User Fee Act (PDUFA) date is May 21, 2007 for this application. SPD465 has the same active ingredient as ADDERALL XR, but is designed to provide ADHD symptom control for up to 16 hours.

SPD503 (guanfacine) - ADHD

- An NDA was submitted to the FDA on August 24, for investigational compound SPD503 extended release, which, if approved, would be the first once daily selective alpha-2A-adrenoceptor agonist for the treatment of ADHD in children aged 6 to 17 years. The PDUFA date for this application is June 24, 2007.

MESAVANCE - Ulcerative Colitis

- The FDA has extended by 90 days the review period for the NDA for MESAVANCE. This extension has been sought by the FDA to allow additional time to review supplemental Phase 1 data which Shire had agreed with the FDA to submit during the review process. The PDUFA date for the application is January 21, 2007.

Human Genetic Therapies (HGT)

- HGT has completed proof of concept studies on three projects and has advanced them into pre-clinical development; namely enzyme replacement therapies for Sanfilippo (Mucopolysaccharidosis IIIA), Metachromatic Leukodystrophy and intrathecal delivery of ELAPRASE for Hunter syndrome patients with significant central nervous system symptoms. Details of these programs will be available during Shire’s third quarter conference call presentation.

Business highlights

Barr Laboratories Inc. (Barr)

- Shire has settled all pending litigation with Barr, in connection with Barr’s Abbreviated New Drug Application (“ANDA”) and its attempt to market generic versions of Shire’s ADDERALL XR for the treatment of ADHD. Barr will not be permitted to market a generic version of ADDERALL XR in the US until April 1, 2009, except for certain limited circumstances, such as the launch of another party’s generic version of ADDERALL XR.

- Shire and Duramed Pharmaceuticals, Inc. (“Duramed”), a subsidiary of Barr have entered into an agreement related to Duramed’s transvaginal ring technology that will be applied to at least five women’s health products, as well as a license to Duramed’s currently marketed oral contraceptive, SEASONIQUE(R) (levonorgestrel/ethinyl estradiol tablets 0.15 mg/0.03 mg and ethinyl estradiol tablets 0.01 mg). Under this agreement, Shire made an initial payment of US$25 million to Duramed for previously incurred product development expenses, and will reimburse Duramed for development expenses incurred going forward up to a maximum of US$140 million over eight years, with an amount capped at US$30 million per annum. Shire has exclusive rights to market these products in the five major European markets of the UK, Germany, France, Italy and Spain and other areas, excluding North America, and to the subsequent sales they will generate on a royalty-free basis.

- Duramed has purchased Shire’s ADDERALL(R) (immediate-release mixed amphetamine salts) product for US$63 million. This transaction was completed at the end of the third quarter.

Warren Pharmaceuticals, Inc. (Warren)

- Shire has in-licensed rights to tissue protective cytokine (TPC) technology under an agreement with Warren. The agreement gives Shire exclusive worldwide rights to develop TPCs in non-Nervous System indications, including renal and genetic disease areas. An upfront payment of US$6 million was payable to Warren, of which US$0.5 million was satisfied by a payment made and expensed to R&D in the three months ended June 30, 2006 and the remaining US$5.5 million was paid and expensed to R&D in the three months ended September 30, 2006.

2006 Outlook

R&D pipeline and new product launches

Shire has a strong product pipeline to support the medium and long-term future growth of the Company. In Q4 2006 and H1 2007 Shire anticipates that it will:

- Launch ELAPRASE in Europe; - Launch MESAVANCE in the US and in Europe; - Launch NRP104 in the US; - Launch DYNEPO in Europe; - Continue the roll out of FOSRENOL in Europe; and - Continue the roll out of DAYTRANA and ELAPRASE in the US.

Timings of launches are subject to the regulatory/governmental approvals process.

Financial Outlook

We are upgrading the previous guidance given as part of the Q2 2006 results, as follows:

We now anticipate 2006 revenue growth to be in the range of 12% to 14% (prior guidance: low double-digit range).

As previously announced, earnings for 2006 will be impacted by the costs associated with the continued development and launch of five new products in 2006 and H1 2007, including DAYTRANA and ELAPRASE, in addition to the roll-out of FOSRENOL across Europe and the new higher strengths of FOSRENOL in the US.

- These launches require additional advertising and promotional spend and, in some cases, additional sales representatives. Also, Shire has been seeking in 2006 to maximize ADDERALL XR’s market share. As a result, SG&A costs are expected to be at the top end of the original guidance range (US$770-800 million);

- 2006 activities include regulatory filings for ELAPRASE, SPD465, SPD503 and MESAVANCE, Phase 3(b) and Phase 4 studies to support new product launches, the transfer of three HGT projects into pre-clinical development and the commencement of Phase 3 trials on Gene Activated Glucocerebrosidase (GA-GCB). R&D spend for the full year is expected to be at the lower end of the original guidance range (US$310-330 million);

- The depreciation and amortization charge for the year will be approximately 30% higher than the 2005 charge reflecting the acquisition of TKT and the amortization of milestone payments for DAYTRANA (prior guidance: 50% higher); and

- The tax rate for the full year is expected to remain at a rate of approximately 28%.

The financial outlook for the full year stated above excludes the accounting impact under US GAAP of the following items:

- The milestone payment of US$50 million paid to New River in February 2006 following the FDA’s acceptance of the filing of NRP104. This increased R&D expense in Q1 2006;

- Upfront payments totaling US$30.5 million paid to Duramed (US$25 million) and Warren (US$5.5 million). These increased the R&D expense in Q3 2006;

- The gain of US$63 million made on disposal of ADDERALL product rights to Duramed;

- A US GAAP adjustment to cost of product sales of US$47 million (prior guidance: US$50 million) to reflect the difference between the accounting fair value and book value of acquired REPLAGAL inventory, all of which has now been charged;

- Shire HGT integration costs estimated at US$6 million in 2006 (prior guidance: US$7 million), of which US$3.9 million was incurred to the end of Q3 2006; and

- The adoption from January 1, 2006 of US GAAP accounting standard SFAS 123R for share based compensation. This is expected to give rise to additional charges estimated at approximately US$45 million, which will be split between costs of product sales, R&D and SG&A in approximate ratios of 10%, 15% and 75% respectively. US$25.8 million was charged across these categories for the nine months ending September 30, 2006 (2005: US$20.6 million adjusted retrospectively).

Including these items would result, under US GAAP, in an estimated increase in cost of product sales of US$50 million, R&D spend in the range of US$395-415 million and SG&A and integration costs between US$805-835 million.

New Accounting Standard - SFAS 123R

Shire’s primary basis of financial reporting is US GAAP. From January 1, 2006 Shire has been required to adopt SFAS 123R in accounting for share-based compensation. This accounting standard applies a fair value methodology in quantifying the accounting charge associated with share-based compensation.

The Company has adopted SFAS 123R according to the modified retrospective method. As a result, comparatives, including accounting periods in 2005, have been retrospectively adjusted.

Revenues from continuing operations for the three months to September 30, 2006 increased by 19% to US$449.4 million (2005: US$376.1 million).

Income from continuing operations (before income taxes and equity method investees) for the three months to September 30, 2006 was US$119.1 million (2005 loss of: US$613.6 million). The difference is primarily due to the write-off of in-process R&D of US$673.0 million in Q3 2005 following the TKT acquisition, and the gain on the sale of ADDERALL of US$63.0 million in Q3 2006. The increased revenues in the period were broadly offset by increased costs in funding Shire’s new product launches.

Cash inflow from operating activities for the three months to September 30, 2006 was US$82.1 million (2005: US$39.1 million). This increase primarily resulted from favorable movements in working capital. Cash and cash equivalents, restricted cash and short-term investments at September 30, 2006 totaled US$984.8 million (December 31, 2005: US$694.0 million).

2. Product sales

For the three months to September 30, 2006 product sales increased by 25% to US$386.2 million (2005: US$309.2 million) and represented 86% of total revenues (2005: 82%).

In Q3 2005 total post acquisition sales were US$16.0 million

(4) Worldwide sales excluding US and Canada

ADDERALL XR for the treatment of ADHD

ADDERALL XR is the leading brand in the US ADHD market with a market share of 26% in September 2006 (2005: 25%). The US ADHD market growth of 4% and the increase in market share contributed to a 9% increase in US prescriptions for ADDERALL XR for the three months to September 30, 2006 compared to the same period in 2005.

Sales of ADDERALL XR for the three months to September 30, 2006 were US$207.6 million, an increase of 25% compared to the same period in 2005 (2005: US$165.9 million). Product sales growth was significantly more than prescription growth, due to price increases in August 2005 and April 2006 and lower levels of pipeline de-stocking compared with Q3 2005.

During October 2005 Shire filed a Citizen Petition with the FDA requesting that the FDA require more rigorous bioequivalence testing or additional clinical testing for generic or follow-on drug products that reference ADDERALL XR before they can be approved. Shire received correspondence from the FDA in April 2006 stating that, due to the complex issues raised requiring extensive review and analysis by the FDA’s officials, a decision cannot yet be reached by the FDA. The FDA did not provide any guidance as to when that decision may be reached.

On August 14, 2006, Shire and Barr announced that all pending litigation in connection with Barr’s Abbreviated New Drug Application (ANDA) and its attempt to market generic versions of Shire’s ADDERALL XR had been settled. As part of the settlement, Barr entered into consent judgments and agreed to permanent injunctions confirming the validity and enforceability of Shire’s US Patents Nos. 6,322,819 (the “‘819 Patent”), 6,601,300 (the “‘300 Patent”) and 6,913,768 (the “‘768 Patent”). Barr has also admitted that any generic product made under its ANDA would infringe the ‘768 patent.

Under the terms of the settlement, Barr will not be permitted to market a generic version of ADDERALL XR in the US until April 1, 2009, except in certain limited circumstances, such as the launch of another party’s generic version of ADDERALL XR. No payments to Barr are involved in the settlement agreement.

Further information about the litigation proceedings relating to the Company’s ADDERALL XR patents can be found in our filings with the US Securities and Exchange Commission, including our Annual Report on Form 10-K for the year to December 31, 2005 and our most recent Quarterly Report on Form 10-Q for the period ended June 30, 2006.

DAYTRANA for the treatment of ADHD

Following its launch in June 2006, DAYTRANA achieved a 1.7% share of the ADHD market by the end of Q3 2006. Sales in this period were US$9.9 million. The addition of DAYTRANA combined with growth in ADDERALL XR share has helped Shire grow its total share of the ADHD market to 29% in the quarter ending September 30, 2006 compared to 26% in the quarter ending September 30, 2005.

CARBATROL for the treatment of Epilepsy

US prescriptions for the three months to September 30, 2006 were down 7% compared to the same period in 2005. This was primarily due to a 5% decline in the US extended release carbamazepine prescription market. CARBATROL’s market share remained constant at 42%.

Sales of CARBATROL for the three months to September 30, 2006 were US$20.4 million, an increase of 27% compared to the same period in 2005 (2005: US$16.1 million). The difference between the increase in sales and decrease in prescriptions is due to price increases in October 2005 and July 2006, lower levels of pipeline de-stocking compared with Q3 2005 and reduced sales deductions.

In July 2006 Impax Laboratories, Inc. (Impax) deployed a sales force to begin promotion of CARBATROL under a promotional services agreement for the US market signed in January 2006.

Patent litigation proceedings with Nostrum Pharmaceuticals, Inc. (Nostrum) relating to CARBATROL are ongoing. On July 17, 2006 the Court entered an order staying discovery in this case until and through September 15, 2006. The parties have requested and the Court has granted a stay of discovery until and through December 29, 2006. No trial date has been set. Nostrum’s 30-month stay under the Hatch-Waxman Act expired on February 6, 2006. Accordingly, the FDA may approve Nostrum’s ANDA, once it meets all regulatory requirements.

On March 30, 2006 the Company was notified that Corepharma LLC (Corepharma) had filed an ANDA under the Hatch-Waxman Act seeking permission to market its generic version of carbamazepine extended release products in 100mg, 200mg and 300mg strengths. Shire Laboratories, Inc. filed suit against Corepharma for the infringement of US Patent No. 5,326,570 (the ‘570 Patent) in the District Court of New Jersey. The lawsuit triggered a stay of FDA approval of Corepharma’s generic products for 30 months from the date of Shire’s receipt of Corepharma’s notice of ANDA filing. No discovery schedule or trial date has been set.

Further information about the litigation proceedings relating to the Company’s CARBATROL patents can be found in our filings with the US Securities and Exchange Commission, including our Annual Report on Form 10-K for the period ended December 31, 2005 and our most recent Quarterly Report on Form 10-Q for the period ended June 30, 2006.

PENTASA for the treatment of Ulcerative Colitis

US prescriptions for the three months to September 30, 2006 were up 4% compared to the same period in 2005 primarily due to a 4% increase in the US oral mesalamine prescription market. PENTASA’s market share remained constant at 18%.

Sales of PENTASA for the three months to September 30, 2006 were US$36.9 million, an increase of 1% compared to the same period in 2005 (2005: US$36.6 million). Sales growth is lower than prescription growth due to the lower levels of pipeline stocking in Q3 2006 partly offset by the impact of the January 2006 price increase.

REPLAGAL for the treatment of Fabry Disease

REPLAGAL was acquired by Shire as part of the TKT acquisition, which was completed on July 27, 2005. Product sales for the three months to September 30, 2006 were US$32.4 million, the majority of which were in Europe. Total sales for REPLAGAL, including pre-acquisition sales (US$8.1m), for the three months to September 30, 2005 were US$24.1 million. This represents a like-for-like increase in sales of 34% which was due to greater European coverage by an increased number of sales representatives, and strong growth in the Rest of the World market.

ELAPRASE for the treatment of Hunter Disease

ELAPRASE was launched at the end of July 2006 and has had a strong start with sales reaching US$4.3 million by the end of Q3 2006.

XAGRID for the treatment of Thrombocythemia

Rest of the World (outside North America) sales were up by 11% to US$13.3 million (2005: US$12.0 million). Sales increased by 7% as expressed in the transaction currencies (XAGRID is primarily sold in Euros), due mainly to strong growth in France and Spain and benefited by 4% from favorable exchange rate movements against the USUS$.

FOSRENOL for the treatment of Hyperphosphatemia

US prescriptions for the three months to September 30, 2006 were up 12% compared to the same period in 2005. This was primarily due to FOSRENOL increasing its share of the total US phosphate binding market, which in September 2006 was 9% (2005: 8.5%), in a market that had itself grown 8% over the same period. FOSRENOL was launched in the US in January 2005.

US sales of FOSRENOL for the three months to September 30, 2006 were up 18% to US$11.4 million (2005: US$9.7 million). The increase in net sales compared to prescription growth is due to price increases in January 2006 and July 2006, larger prescription sizes due to the addition of the 1g and 750mg units and lower sales deductions, partially offset by destocking in Q3 2006.

European sales of FOSRENOL for the 3 months to September 30, 2006 were US$0.8 million, giving total FOSRENOL sales worldwide of US$12.2 million.

FOSRENOL was launched in Austria, Ireland, Sweden and Denmark in December 2005 and in South Korea in June 2006.
