Leiden, The Netherlands, September 25 2007 - Dutch biotechnology company Crucell N.V. (Euronext, NASDAQ: CRXL, Swiss Exchange: CRX) today stated that it wishes to emphasize that the discontinuation of Merck's HIV phase I and II studies, as announced on Friday September 21, is not related to the use of Crucell's PER.C6® technology. The Company further added that it reiterates its expectations for a combined full year 2007 total revenue and total other operation income in the € 220 to 225 million range and that the Company aims to achieve cash break-even on its 'net cash from operating activities' line in the cash flow statement for the full year 2007.

 

"While the vaccine is produced on Crucell's PER.C6® technology, the discontinuation of the study appears in no way related to the safety or efficacy of the PER.C6® production technology and therefore has no impact on either Crucell's licensing activities or Crucell's partnership with Merck with respect to Crucell's PER.C6® and AdVac® technologies as announced two weeks ago", said Dr. Jaap Goudsmit, Crucell's Chief Scientific Officer. "We empathize with all people at risk of AIDS for whom this result is a set back."

 

Crucell also reiterates its expectations for a combined full year 2007 total revenue and total other operation income in the € 220 to 225 million range and that the Company aims to achieve cash break-even on its 'net cash from operating activities' line in the cash flow statement for the full year 2007. "We had not incorporated any income from the Merck HIV program in our guidance for 2007. As the program was in a phase II study it was not at all expected to enter the market within the next couple of years to generate royalty-based income for Crucell. We therefore wish to emphasize that our guidance for 2007 has not changed as a result of this event," said Ronald Brus, Chief Executive Officer. "Bringing an HIV vaccine to market has always been considered to be a major challenge."
