Shire Completes Fosrenol(R) Roll-Out in Major European Markets With Launch in SpainNon-Calcium Phosphate Binder for the Management of hyperphosphataemia Now Available in 24 Countries
NOT FOR DISTRIBUTION IN THE UNITED STATES
BASINGSTOKE, England, January 17 (HSMN NewsFeed) -- Shire plc (LSE: SHP, NASDAQ: SHPGY, TSX: SHQ) announces that with the launch today in Spain of FOSRENOL (lanthanum carbonate), a non-calcium phosphate binder, Shire is celebrating the completion of the launch roll-out in the major European markets. FOSRENOL is the first of the company's medicines developed in-house from research molecule to market.
Chronic Kidney Disease (CKD) is a progressive condition classified in five stages culminating in Stage 5 (or ESRD), a condition typified by a complete loss of kidney function, usually requiring the patient to undergo dialysis or kidney transplantation.
CKD is recognized as a growing 'silent epidemic' affecting up to 1 in 10 people(5), due in part to rising obesity rates and an increasing number of people with diabetes.(6) CKD can cause numerous serious health consequences for patients, including hyperphosphataemia.
Effective phosphate control is critical for these patients because, if not managed successfully, hyperphosphataemia can lead to significant health problems. These include CKD-related mineral and bone disorder, resulting in painful, brittle bones that may fracture or become deformed and cardiovascular disease, which accounts for almost half of all deaths in dialysis patients.

"As CKD progresses, its management becomes increasingly challenging for patients as dietary restrictions and fluid limitations become paramount," said David Milton, Senior Vice President, Shire Renal Business Unit. "By the time they reach CKD stage 5, patients are not only likely to be on dialysis, but are often taking as many as 10 to 12 different medications(9), which can amount to 25 tablets a day or more, for the different complications of CKD including hyperphosphataemia.
"Shire is proud to have developed FOSRENOL from research molecule to the healthcare market as an effective non-calcium monotherapy treatment option for ESRD patients with hyperphosphataemia. FOSRENOL is provided as a simple one tablet per meal dose for the majority of patients," added Milton.
"Shire participated with the other phosphate binder manufacturers at a recent Shire requested US Food and Drug Administration Cardiovascular and Renal Drugs Division Advisory Committee. The majority of the members on the Advisory Committee voted to recommend the use of phosphate binders to treat hyperphosphataemia in CKD Stage 4 patients. As a result Shire is working to identify the regulatory pathway forward for the use of FOSRENOL in this group of patients," he added.
To date, over 5,200 patients have been treated with FOSRENOL during an extensive clinical development program.(10) Globally over 100,000 patients have been prescribed FOSRENOL since it was launched in 2005.(10) FOSRENOL has an extensive long-term safety data package extending out to six years.
Following its launch in Spain, FOSRENOL is now available in 24 countries worldwide.
Notes to editors:
Phosphate, which is found in nearly all foods, is absorbed from the gastrointestinal (GI) tract into the blood stream. When the kidneys fail, they no longer effectively filter out phosphate, even with the help of blood-cleansing dialysis. While the normal adult range for phosphate is 0.8mmol/L (2.5 mg/dL) to 1.4mmol/L (4.5 mg/dL), the blood phosphorus levels of many patients on dialysis can exceed 2.1mmol/L (6.5 mg/dL ). Such levels have been linked to a significantly higher complications and death risk for patients who have undergone at least one year of dialysis(11) with over 70 per cent of these patients developing hyperphosphataemia.(3)
Chronic Kidney Disease disrupts the delicate interplay between the body's levels of calcium, parathyroid hormone (PTH) and vitamin D, leading to hyperphosphataemia. Over time, hyperphosphataemia can ultimately lead to calcification in the heart, lung and some arteries.(12) Accumulating evidence shows that hyperphosphataemia contributes to cardiovascular disease, which accounts for almost half of all deaths among dialysis patients.(13) Studies have shown that cardiovascular mortality in dialysis patients aged 25-34 years is more than 5 times greater than that in people aged 65-74 in the general population.(14)
Since dialysis and diet restrictions alone generally cannot control phosphate levels, patients traditionally manage hyperphosphataemia by taking phosphate binding agents with every meal and snack. Such binders "soak up" phosphate in the gastrointestinal tract, before it can be absorbed into the blood.
About FOSRENOLŽ (lanthanum carbonate)
FOSRENOL is indicated to reduce serum phosphate in adult patients with ESRD.(1)
FOSRENOL works by binding to dietary phosphate in the GI tract; once bound, the lanthanum/phosphate complex cannot pass through the intestinal lining into the blood stream and is eliminated from the body. As a consequence, overall phosphate absorption from the diet is decreased significantly.
FOSRENOL is available in a broad range of dosage strengths including 500-milligram (mg), 750-mg, and 1000-mg tablets.(1) Patients taking FOSRENOL can achieve serum phosphate target levels with as little as one tablet per meal.
FOSRENOL was approved by the FDA in October 2004. In March 2005 regulatory authorities in the EU granted marketing authorization for FOSRENOL in sixteen member states, thus completing the first step in securing marketing approval throughout Europe. Later, the European process was completed resulting in recommendation for approval in the remaining eleven member states. FOSRENOL is now available in 24 countries, including Italy, France, Germany, UK and the US and continues to be launched in new markets around the world. The company has out-licensed the rights to develop, market and sell FOSRENOL in Japan to Bayer Yakuhin Ltd.
Patients with renal insufficiency may develop hypocalcaemia. Serum calcium levels should therefore be monitored at regular time intervals for this patient population and appropriate supplements given.
No data are available in patients with severe hepatic impairment. Caution should, therefore, be exercised in these patients, as elimination of absorbed lanthanum may be reduced.
FOSRENOL should not be used during pregnancy.
Patients with acute peptic ulcer, ulcerative colitis, Crohn's disease or bowel obstruction were not included in clinical studies with Fosrenol.
The most commonly reported Adverse Drug Reactions (ADRs) are gastrointestinal reactions such as abdominal pain, constipation, diarrhoea, dyspepsia, flatulence, nausea and vomiting. These are minimized by taking FOSRENOL with food and generally abate with time with continued dosing. Hypocalcaemia was the only other commonly reported adverse reaction.
Full prescribing information is available on request.
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 and hyperactivity disorder (ADHD), human genetic therapies (HGT), gastrointestinal (GI) and renal diseases. The structure is sufficiently flexible to allow Shire to target new therapeutic areas to the extent opportunities arise through acquisitions. 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. Shire believes that a carefully selected portfolio of products with strategically aligned and relatively small-scale sales forces will deliver strong results.
