ZEFFIX - Chronic hepatitis B infection
Royalties from sales of ZEFFIX for the year to December 31, 2008 were $40.3 million, a decrease of 2% compared to the same period in 2007 (2007: $41.0 million). On a constant exchange rate basis, royalties from sales of ZEFFIX fell 8%.
OTHER
Other royalties are primarily in respect of REMINYL and REMINYL XL (known as RAZADYNE and RAZADYNE ER in the US), for the symptomatic treatment of mild to moderately severe dementia of the Alzheimer's type. The range is marketed worldwide (excluding the UK and the Republic of Ireland where Shire has exclusive marketing rights) by Janssen Pharmaceutical N.V., an affiliate of Johnson & Johnson.
Sales of the REMINYL/RAZADYNE range continue to grow in most countries, however the entry of generic versions of RAZADYNE and RAZADYNE ER into the US market has significantly decreased sales in that region. This decline was expected and is included in our forecasts.
Information on the RAZADYNE patent litigation (which rendered the relevant patent invalid in August 2008) and RAZADYNE ER patent litigation (which is ongoing) can be found in our filings with the SEC in our Annual Report on Form 10-K for the year to December 31, 2007 and in our Quarterly Report on Form 10-Q for the period ended September 30, 2008.
