Crucell Presents Update on Products and Programs at New York Analyst Meeting


New York, November 16, 2006 - Dutch biotechnology company Crucell N.V. (Euronext, NASDAQ: CRXL; Swiss Exchange: SW CRX) today presents an update on the Company’s strategy, organization, product sales, research and development programs, and financial outlook in a meeting with analysts and investors held in New York. A live audio webcast of the meeting, featuring the presentation slides, can be accessed via the homepage of Crucell’s website at, and will be archived and available for replay following the event.

Crucell will continue to capitalize on the rapidly growing vaccine market through increasing sales of marketed vaccines and developing and introducing new vaccines. The Company is leveraging its PER.C6® technology in the rapidly growing protein market. On November 8, Crucell and DSM Biologics announced the opening of the PERCIVIA PER.C6® Development Center in Cambridge, Massachusetts. PERCIVIA will continue to further develop the PER.C6® technology and provide turnkey solutions for the production of pharmaceutical proteins to licensees utilizing the PER.C6® human cell line. In addition to licensing its technology, Crucell intends to develop its own products in the area of blood proteins, produced on PER.C6® technology. Crucell is pursuing research and development of the blood-clotting Factor V Leiden/Cambridge and is investigating production of improved versions of currently marketed proteins on its PER.C6® production platform.

“Crucell is focused on future growth both organically and through acquisitions. We are optimizing our sales of marketed products and continue to generate acceptance of our technologies throughout the industry. We invest significantly in research and development for long-term upside,” said Crucell’s Chief Executive Officer, Ronald H.P. Brus MD. “We reiterate that our financial position remains strong and we aim to achieve cash breakeven in 2007.”

Product programs update

Crucell is optimizing Inflexal® V through the use of the adjuvant ISCOM-MATRIX-M. The primary target group for the ISCOM-MATRIX-M adjuvanted seasonal vaccine are the elderly. In relation to pandemic vaccine, Crucell has received an EU grant to develop a virosome-ISCOM-MATRIX-M adjuvanted H5N1 vaccine.

PER.C6®-based seasonal influenza vaccines, developed in partnership with sanofi pasteur, have entered Phase I studies in both healthy adults and in the elderly, both started in the third quarter 2006.

Crucell is involved in different programs to address the pandemic threat of avian influenza. An egg-based H9N2 vaccine, developed with the University of Leicester, entered Phase I/II clinical studies in May 2006. Results are expected in the second half of 2007. The PER.C6®-based FLUPAN H7N1 Phase I study, comparing the cell-based vaccine to egg-based alternatives, started in September 2006.

Children’s vaccines
Crucell’s Quinvaxem(TM) vaccine was approved by the Korean FDA in March 2006 and received World Health Organization (WHO) pre-qualification in September 2006. The inclusion of Hepatitis B into this vaccine potentially allows additional childhood vaccines to be added to the childhood vaccination schedule. These vaccines could include a hepatitis A vaccine, a malaria vaccine or a tuberculosis vaccine.

The pediatric dose of the hepatitis A vaccine Epaxal® has been shown in a phase III study to be effective in combination with other children’s vaccines, providing immediate and long lasting protection.

Our malaria vaccine has received all necessary approval to enter Phase I clinical study which is expected to start in the fourth quarter of 2006 at Vanderbilt University in the US. The clinical trial will be a randomized, double-blind, placebo-controlled study that will test the vaccine in a dose-escalation study involving 96 healthy volunteers. Studies in large animal models demonstrated that Crucell’s recombinant Ad35 vaccine provides better immune responses than the existing RTS,S candidate vaccine.

A PER.C6®-based tuberculosis vaccine developed in partnership with Aeras entered Phase I studies in the US in October 2006. The study is expected to be completed in 2007. Preclinical studies demonstrated that Crucell’s recombinant Ad35 tuberculosis vaccine provided effective protection after a single shot.

Travelers’ vaccines and other programs
Crucell’s Epaxal® hepatitis A vaccine has a potential use for protecting travelers against hepatitis A when traveling to hepatitis A endemic regions. Crucell is currently negotiating with the US Food and Drug Administration for licensing Epaxal® in the US.

Flavimun®, a vaccine against yellow fever, is currently in Phase III studies and is expected to be licensed and launched in 2007.

Crucell’s Ebola vaccine developed in partnership with the Vaccine Research Center (VRC) of the NIH, entered Phase I studies in September 2006. Phase I study results are expected in the fourth quarter 2007.

The Company’s anti-rabies monoclonal antibody cocktail has received IND approval in October 2006. Phase I studies are planned in the US starting in the fourth quarter of 2006 and in the Philippines in the first quarter of 2007.

Crucell’s West Nile virus vaccine is currently in a Phase I, double-blind, placebo- controlled study for adverse effects and immunogenicity. Results are expected in the fourth quarter 2006.

Factor V Leiden/Cambridge (L/C)
The Company acquired all the intellectual property rights for its novel Factor V Leiden/Cambridge program. Factor V L/C will be developed for the prevention and treatment of bleeding in haemophiliacs and non-haemophiliacs at high risk. The Company estimates the market potential for Factor V L/C at over
US$3 billion.

Financial Outlook

The Company narrowed its guidance for combined revenue and other operating income for 2006 to €140 - €150 million. Due to the late start of the flu season the Company expects very strong fourth quarter revenues as a result of sales of its Inflexal® V influenza vaccine. Sales of Crucell’s Quinvaxem(TM) started in October 2006.

The total decrease in cash over 2006 will exceed the company’s prior estimate of €33 million to €38 million by up to €14 million, as a result of the cash acquisition of Berna Products Corp, Inc. and related costs. The Company aims to achieve cash break-even in 2007.
