Leiden, The Netherlands (August 12, 2008) - Dutch biopharma company Crucell N.V. (Euronext, Nasdaq: CRXL; Swiss Exchange: CRX) today announced its financial results for the second quarter of 2008, based on International Financial Reporting Standards (IFRS). These financial results are unaudited.

Highlights:
DSM Biologics and Crucell announced another breakthrough in the production of IgG antibodies using Crucell's PER.C6® technology. By employing the PER.C6® human cell line and proprietary XD(TM) technology, a record yield of over 27 grams per liter has been achieved.
Product sales increased driven by continued growth of paediatric and travel vaccines; in particular Quinvaxem®, Epaxal® and Dukoral®.
Crucell's rabies monoclonal antibody cocktail entered a second Phase II clinical trial in the Philippines in May 2008. Preliminary results of Crucell's U.S. Phase II study are expected to be presented on October 1 at the 19th annual RITA meeting in Atlanta.
Crucell announced three non-exclusive STAR® research license agreements; with Bioceros, covering the production of monoclonal antibodies; with Celltrion, Inc. for the manufacturing of biopharmaceuticals and with Toyobo Gene Analysis Co. LTD. for the production of recombinant proteins for third-party customers.
DSM Biologics and Crucell announced to have entered into an agreement with Avid Bioservices to join their Vendor Network.
Crucell's operational excellence program "Healthy Ambition" is being rolled out at full steam. Target savings of €30 million by the end of 2009.
Initial net cost savings of €3 million expected in the second half of 2008.
Crucell's shareholders appointed Mr. Steve Davis as member of the Supervisory Board at the Annual Meeting for Shareholders, held in May. Dr. Cees de Jong was appointed as a member of the Board of Management for a term of four years.
Financial Highlights:
Combined total revenue and other operating income for the quarter of €59.6 million compared to €39.4 in the same quarter of 2007. The increase of 51% (63% in constant currencies) was driven by strong sales of paediatric vaccines, in particular by Quinvaxem®, higher sales of travel vaccines as well as higher license fees.
Increase of license revenues driven by milestone payments as a result of the start of two phase II clinical studies of Crucell's rabies monoclonal antibody cocktail.
Gross margins of 36% compared to 39% in the second quarter of 2007 due to a variation in the product mix in this quarter. Gross margins in the second half of 2008 are expected to be positively influenced by the seasonality of our flu product (Inflexal® V) in particular.
Net loss in the second quarter of 2008 narrowed by 57% to €7.9 million versus a net loss of €18.2 million in the same quarter of 2007.
Cash and cash equivalents at the end of the second quarter amounted to €106.9 million versus €163.2 million at year-end 2007. Deterioration of cash flow and working capital in the second quarter of 2008 was due to the seasonality of our business, in which we build inventory in the first half of the year to sell our products in the second half of the year. Full year expectations of positive cash flow are reiterated.
Net cash used in operating activities in the second quarter of 2008 was €18.0 million compared to net cash used in operating activities of €10.2 million in the same quarter of 2007.

Crucell's Chief Executive Officer Ronald Brus said:

"In the second quarter of 2008 we saw strong growth of our paediatric vaccines, driven by Quinvaxem®. This innovative, fully-liquid pentavalent vaccine was described by the World Health Organization (WHO) as 'one of the most advanced immunization products available, enabling countries to make a large stride towards their health targets'. We are very proud to have this product in Crucell's paediatric portfolio and expect to see continued growth going forward."

"Our travel and endemic vaccines, in particular Epaxal® and Dukoral®, also showed solid growth compared to the second quarter of 2007. We will continue to go after untapped markets, amongst others in the U.S., to expand our geographical presence of our travel and endemic vaccines."

"Together with DSM Biologics we achieved another breakthrough in the production of IgG antibodies using Crucell's PER.C6® technology. A record yield of over 27 grams per liter was achieved, which surpasses all other production systems currently available in the market."

"We are rolling out our operational excellence program Healthy Ambition at full steam. As an integral part of our growth strategy, Healthy Ambition's goal is to improve overall business performance and reduce costs with 15% by the end of 2009 resulting in an overall run-rate of €30 million savings."

"In the first half of the year we also started two Phase II clinical studies (in the U.S and in the Philippines) for our Rabies Monoclonal Antibody Cocktail, a collaboration with sanofi pasteur using Crucell's PER.C6® technology. The Rabies Monoclonal Antibody Cocktail is to be used in combination with rabies vaccines for post-exposure prophylaxis against this fatal disease. Preliminary results of our U.S. study are expected to be presented in the U.S. on October 1 at the 19th annual RITA meeting in Atlanta."

"Based on our second quarter results we reiterate our guidance of combined total revenue and total other operating income for the full year 2008 to grow by 20%[1]. We further expect higher margins and positive cash flow."

Product and Business Update:

Product Update
Product sales for the second quarter of 2008 amounted to €48.4 million and represent sales of paediatric vaccines (56%), travel & endemic vaccines (29%) and other products (15%).

Paediatric
In the second quarter of 2008 we saw good growth of our paediatric vaccines, mainly driven by Quinvaxem®.
Quinvaxem®: Fully liquid pentavalent vaccine against five important childhood diseases.
Hepavax-Gene®: Recombinant vaccine against hepatitis B.
Epaxal® Junior: Paediatric dose (0.25mL) of Epaxal® - the only aluminum-free vaccine for children against hepatitis A. The product is currently under registration in selected countries worldwide. Sales in South America have started and European launch is being planned.
MoRu-Viraten®: Vaccine for protection against measles and rubella (for all age groups).
Travel and Endemic
The second quarter of 2008 showed continued growth of our travel and endemic portfolio, where Epaxal® and Dukoral® in particular showed growth compared to the second quarter of 2007. We continue to see significant untapped demand and geographical expansion potential of our travel portfolio.
Epaxal®: The only aluminium-free vaccine against hepatitis A.
Vivotif®: The only oral vaccine against typhoid fever.
Dukoral®: The only oral vaccine against diarrhea caused by cholera and ETEC (enterotoxigenic E.coli).
Respiratory
Inflexal® V: A virosomal adjuvanted vaccine against influenza (for all age groups). Due to the seasonality of the product, we build inventory in the first half of the year to sell the respiratory products in the second half of the year.
Pipeline Update
Flavimun® - Live Attenuated Yellow Fever Vaccine: Crucell's management expects the registration submission of the Yellow Fever vaccine in Switzerland before the end of 2008.
Influenza - Seasonal Flu Vaccine (FluCell collaboration with sanofi pasteur): The seasonal influenza vaccine developed by Crucell's partner sanofi pasteur, using PER.C6® technology. Phase II testing of the cell based influenza vaccine was initiated in the U.S. in November 2007. Phase II trials involving healthy adult volunteers in the U.S. focus on the safety profile and immunogenicity of the cell-based vaccine.
Influenza - H9N2 Pandemic Flu Vaccine: Completed in July 2008. Phase I and II studies were carried out and no serious adverse side effects were reported. In the H9N2 trial Crucell's licensed vaccine method, i.e. a virosomal vaccine was compared to methods less suitable for seasonal vaccine production. As expected the immune response to the unlicensed whole virus vaccine, in particular when adjuvanted with aluminium, appeared to be the most suitable way to induce immunity against a pandemic H9N2 influenza strain and possibly H5N1 strains. Results from this trial showed that subjects who were vaccinated with the virosomal vaccine less frequently reported pain as compared to subjects who were vaccinated with whole virus (with or without adjuvation). We have recently shown (Radosevic et al., Vaccine 2008; 26: 3640-46) that our licensed strategy for seasonal influenza vaccination could also be used for pandemic influenza strains when the immune response was enhanced by additional adjuvants. Within the PanFluVac EU consortium this approach will be tested for a virosomal H5N1 vaccine in humans in 2009.
Rabies Human Monoclonal Antibody Cocktail: Crucell's rabies monoclonal antibody cocktail, a collaboration with sanofi pasteur using Crucell's PER.C6® manufacturing technology, has entered two Phase II clinical trials (in the US and in the Philippines). The start of these Phase II studies triggered the first milestone payments of a total of up to €66.5 million. This antibody cocktail is to be used in combination with a rabies vaccine for post-exposure prophylaxis against this fatal disease. Based on promising Phase I data in 2007, showing no serious adverse effects and well tolerated treatment, Crucell was granted a Fast Track designation by the FDA Department of Health and Human Services. Crucell will be responsible for the manufacturing of the final product and has retained exclusive distribution rights in Europe, co-exclusive distribution rights in China and the rights to sell to supranational organizations such as UNICEF. Preliminary results of our U.S. study are expected to be presented in the U.S. on October 1 at the 19th annual RITA meeting in Atlanta, at the Centers of Disease Control and Prevention.
Malaria Vaccine based on AdVac®/PER.C6® Technology: Crucell and its partner, the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), are conducting a Phase I trial in the U.S. The study is being carried out on two sites, VanderBilt and Stanford University. The first three cohorts, comprising of 18, 17 and 18 volunteers respectively, have been enrolled. Enrollment for the fourth and final group of volunteers is expected to start soon. Initial findings of this Phase I trial are expected to be available in 2008.
Tuberculosis Vaccine based on AdVac®/PER.C6® Technology: The development of this vaccine is being carried out in collaboration with the Aeras Global TB Vaccine Foundation. A US Phase I trial (in BCG naïve individuals) has been completed, indicating that the vaccine candidate is safe in healthy adults in the US. The results of a second study which took place in South Africa, launched in May 2007, were presented in April at the 'Tuberculosis Vaccines for the World' conference in Atlanta. Preliminary data show encouraging results, whereby CD8 immune responses are considerably higher than previously ever seen in a tuberculosis vaccine study. A third phase I study in healthy adults in St. Louis, US was launched in December 2007 and focuses on the immunogenicity and safety of two AERAS-402/Crucell Ad35 boost doses administered at three to six month intervals after BCG priming in healthy adults.
Ebola Vaccine based on AdVac®/PER.C6® Technology: For the Phase I study for the Ebola vaccine, which Crucell is developing in partnership with the Vaccine Research Center (VRC) of the National Institute of Allergy and Infectious Diseases (NIAID), two groups of 16 volunteers have been enrolled and vaccinated. The clinical data is still blinded, however initial indications suggest that the vaccine is safe at the tested doses and appears to be immunogenic in a subset of subjects.
Blood Coagulation Factor VL/C: Preclinical work on this program continues but conclusive proof of concept is not expected in the near future.
HIV Vaccine based on AdVac®/PER.C6® Technology: The Investigational New Drug Application (IND) for Phase I of the trial with Harvard Medical School (supported by the NIH) was approved by the FDA in January 2008. In April, Crucell announced that the novel recombinant vaccine (using the adenovirus serotype 26 (rAd26) as vector), which is jointly developed with the Beth Israel Deaconess Medical Center (BIDMC), has gone into a Phase I clinical study to test a new HIV vaccine. The rAd26 vector is specifically designed to avoid the pre-existing immunity to the more commonly used adenovirus serotype 5 (Ad5). The phase I clinical study is being conducted at the Brigham and Women's Hospital (BWH) in Boston and is focused on assessing the safety and immunogenicity of the vaccine. The study involves 48 healthy volunteers.
H5N1 - Human Monoclonal Antibodies against Flu: Crucell's scientists discovered a set of 21 human monoclonal antibodies that provides immediate protection and neutralizes the broadest range of H5N1 strains in preclinical models. These were found to be able to neutralize the H5N1 virus of avian influenza, which currently presents a global threat. The most potent of the antibodies was shown to neutralize the broadest range of H5N1 strains that have emerged between 1997 and 2004. This antibody prevents flu, in pre-clinical models, when given twenty four hours before a challenge with a lethal dose of the pathogenic H5N1 virus. When given three days after infection, it also was shown to prevent death and cure the disease. Therefore this antibody may provide a powerful tool in pandemic preparedness.

Healthy Ambition:
After a phase of thorough analysis and business process redesign, the operational excellence program Healthy Ambition is now being rolled out into Crucell. Important elements of the program are: product portfolio optimization, process and infrastructure optimization, network rationalization and further integration and streamlining of various functions. Target savings of €30 million are expected to be achieved by the end of 2009. In the second half of 2008 net savings of €3 million are expected.

PER.C6® technology platform:
DSM Biologics and Crucell announced another breakthrough in the production of IgG antibodies using Crucell's PER.C6® technology. By employing the PER.C6® human cell line and proprietary XD(TM) technology, a record yield of over 27 grams per liter has been achieved. In March 2008 a yield of 15 grams per liter was reported. This milestone is the new manufacturing paradigm for mammalian cell culture to produce protein products effectively, where the industry has struggled to date with low yields and unstable platforms. This record surpasses all other production systems including those previously set by PER.C6® technology itself.

Licensing Agreements:
Crucell announced a non-exclusive STAR® research license agreement with Bioceros. The license agreement covers the production of monoclonal antibodies. Financial details of the agreement were not disclosed.
Crucell announced a non-exclusive STAR® research license agreement with Celltrion, Inc. for the production of recombinant proteins. Under the agreement, Celltrion will evaluate Crucell's STAR® technology for generating cell lines for the manufacturing of biopharmaceuticals. Financial details of the agreement were not disclosed.
Crucell announced a non-exclusive STAR® research license agreement with Toyobo Gene Analysis Co. LTD. Under the agreement, Toyobo Gene Analysis will evaluate Crucell's STAR® technology for generating cell lines for the production of recombinant proteins for third-party customers. Financial details of the agreement were not disclosed.

Vendor Network:
DSM Biologics and Crucell announced to have entered into an agreement with Avid Bioservices, Inc. of Tustin, California to join their Vendor Network. Under the terms of the agreement, Avid will be a pre-approved contract manufacturer for licensees of the PER.C6® cell line located in the western U.S. Avid is the first U.S.-based contract manufacturer to be awarded this status.

Financial Review

Total Revenue and Other Operating Income
Total revenue and other operating income was €59.6 million for the second quarter of 2008, an increase of 51% compared to the same quarter of 2007 (63% in constant currencies). The increase was driven by continued strong sales of paediatric and travel vaccines as well as higher license fees.
Increase of license revenues was driven by milestone payments as a result of the start of two Phase II clinical studies of our Rabies program.

Product sales for the second quarter amounted to €48.4 million and represent sales of paediatric vaccines (56%), travel vaccines (29%) and other products (15%).
License revenues were €5.5 million in the second quarter, an increase of €4.0 million compared to the same quarter of 2007. License revenues consist of initial payments from new contracts as well as milestones and other payments on existing contracts.

Service fees for the quarter were €2.3 million, compared to €3.2 million last year. Service fees represent revenue for product development activities performed under contracts with partners and licensees.

Total other operating income was €3.4 million for the quarter, compared to €2.4 million in the second quarter of 2007.

Cost of Goods Sold
Cost of goods sold for the second quarter of 2008 amounted to €35.8 million, €34.0 million of which represents product costs and the remainder of €1.7 million the cost of service and license activities.

Gross operating margins of 36% compared to 39% in the second quarter of 2007 due to a variation in the product mix in this quarter. Gross margins in the second half of 2008 are expected to be positively influenced by the seasonality of our flu product (Inflexal® V) in particular.

Expenses
Total expenses consist of research and development (R&D) expenses, marketing and sales (M&S) and general and administrative (G&A) expenses. Total expenses for the period were €33.5 million for the second quarter, representing a €1.7 million decrease over the same period in 2007.

R&D expenses for the second quarter amounted to €17.6 million, which represents a €0.8 million increase versus the second quarter of 2007. The increase can be attributed to the timing of specific R&D expenses during the year. Overall R&D spending for the full year is expected to be around € 70 million.

M&S expenses for the quarter were €8.1 million, which represents a €1.3 million decrease versus the second quarter of 2007. This decrease was due to higher one-off expenses in the same quarter last year.

G&A expenses for the second quarter of 2008 were €7.8 million and represent a decrease of €1.2 million over the same quarter in 2007, which include costs related to the 'Healthy Ambition' program.
Net financial income in the second quarter of €2.3 million was the result of foreign exchange gains mainly caused by the strengthening of the Swiss Franc against the Euro.

Net Loss
The Company reported a net loss of €7.9 million for the second quarter of 2008 compared to €18.2 million in the same period of 2007. This amounted to €0.12 net loss per share, compared to a net loss per share of €0.28 in the second quarter of 2007.

Balance Sheet
Tangible fixed assets amounted to €148.5 million on June 30, 2008. Intangible assets represent assets acquired in acquisitions and amounted to €84.0 million. This figure represents acquired in-process research and development; developed technology; patents and trademarks; and value of customer and supplier relationships.

Investments in associates and joint ventures amount to €8.7 million and mainly represent investments in AdImmune and PERCIVIA. The Company's investment in Galapagos NV is classified under available-for-sale investments.
Total equity on June 30, 2008 amounted to €413.3 million. A total of 65.7 million ordinary shares were issued and outstanding on June 30, 2008.

Cash Flow and Cash Position
Cash and cash equivalents decreased by €15.0 million in the second quarter to €106.9 million.

Reduction of cash flow in the second quarter was due to the seasonality of our business, in which we build inventory in the first half of the year to sell our products in the second half of the year.

Net cash used in operating activities in the second quarter of 2008 was €18.0 million. Overall investments in net working capital increased mainly due inventory build-up in preparation for the flu season as well as accounts receivable.

In the second quarter net cash from investing activities amounted to €1.3 million. In the quarter net cash from financing activities amounted to €2.5 million.

Outlook 2008:
Crucell expects combined full year 2008 total revenue and total other operating income to grow by 20% in constant currencies[1]. The Company expects higher margins compared to 2007 and positive cash flow.

Phasing in 2008:
We expect revenues and operating income to be phased throughout 2008 like in 2007. As expected, cash flow and working capital deteriorated significantly in the first half of 2008 due to the seasonality of our business in which we build inventory in the first half of the year to sell our products in the second half. We expect the negative cash flow in the first nine months to reverse in the final quarter of 2008, to end the year with a positive cash flow.
