Litigation proceedings concerning Shire's ADDERALL XR patents are ongoing. Further information on this litigation can be found in our filings with the US Securities and Exchange Commission ("SEC") including our Annual Report on Form 10-K for the year to December 31, 2007.
VYVANSE - ADHD
VYVANSE was launched in the US market in July 2007. Product sales for the three months to September 30, 2008 were $96.0 million (2007: $10.6 million) representing a 47% increase compared to sales of $65.2 million in Q2 2008.
Product sales growth was driven by a 19% increase in prescription demand compared to Q2 2008, a price increase and the stocking impact of the new dosage strengths. For the three months to September 30, 2008 VYVANSE's average quarterly market share was 9.0% (2007: 2.4%) of the US ADHD market.
By October 17, 2008 VYVANSE had achieved a US ADHD average weekly market share of 10.2%, based on weekly prescription volumes.
DAYTRANA - ADHD
Product sales for the three months to September 30, 2008 were $18.1 million (2007: $9.4 million). Prescriptions declined by 14% from the same period last year due to a reduction in DAYTRANA's average quarterly market share of the US ADHD market to 1.6% (2007: 2.1%).
Despite the decrease in prescriptions compared to 2007, sales of DAYTRANA grew 93% compared to the same period last year due to lower sales deductions in 2008 over 2007, when a provision was made for returns following the voluntary market withdrawal of a limited number of DAYTRANA patches.
On August 19, 2008 Shire announced a voluntary recall of two lots of
DAYTRANA patches because these patches did not meet their release liner
removal specifications which may have resulted in some patients and
caregivers having difficulties removing the liners. The voluntary recall
was not due to safety issues. Shire and
