Aeras commits further USD$5 million to existing TB research agreement with Crucell

Leiden, The Netherlands, March 7, 2007 - Dutch biotechnology company Crucell N.V. (Euronext, NASDAQ: CRXL) today announced it will receive up to USD$5 million from Rockville, Maryland-headquartered Aeras Global TB Vaccine Foundation to support the advanced development of the candidate AdVac-based tuberculosis vaccine.

"This technology, which is based on one of the most advanced vector delivery systems for induction of cellular immunity, represents an important part of the portfolio of vaccines we are developing against tuberculosis," said Dr. Jerald C. Sadoff, President & CEO of Aeras Global TB Vaccine Foundation. "We are excited about our continued collaboration with Crucell to support the process development and manufacturing of this promising vaccine candidate."

In March 2004, Aeras and Crucell entered into a collaborative agreement for the development of a PER.C6® and AdVac®-based TB vaccine. The vaccine entered the phase I clinical trial in October 2006.

"Aeras' commitment toward the development of a tuberculosis vaccine is highly commendable," said Crucell's Chief Scientific Officer, Dr. Jaap Goudsmit. "We feel such a pledge is very important as it strengthens not only the basis of our partnership but also highlights the importance of our technologies."

About tuberculosis

Tuberculosis is the world's second deadliest infectious disease behind AIDS, with 8 to 9 million new cases discovered each year. According to the World Health Organization (WHO), nearly 2 million people die from TB each year. One third of the world's population has been infected with the TB bacillus and current treatment takes 6-9 months. Failure to comply with drug treatment breeds drug resistance, which is rising dangerously in many parts of the world. The current TB vaccine Bacillus Calmette-Guérin (BCG), developed over 80 years ago, reduces the risk of severe forms of TB in early childhood, but has variable efficacy against pulmonary TB for adolescents and adults.

About AdVac® technology and Ad35

AdVac® technology is a vaccine technology developed by Crucell and is considered to play an important role in the fight against emerging and re-emerging infectious diseases, and in biodefense. The technology supports the practice of inserting genetic material from the disease-causing virus or parasite into a 'vehicle' called a vector, which then delivers the immunogenic material directly to the immune system. Most vectors are based on an adenovirus, such as the virus that causes the common cold. The AdVac® technology is specifically designed to manage the problem of pre-existing immunity in humans against the most commonly used recombinant vaccine vector, adenovirus serotype 5 (Ad5), without compromising large-scale production capabilities or the immunogenic properties of Ad5. AdVac® technology is based on adenovirus vectors that do not regularly occur in the human population, such as Ad35. In contrast to the AdVac® vectors, antibodies to Ad5 are widespread among people of all ages and are known to lower the immune response to Ad5-based vaccines, thereby impairing the efficacy of these vaccines. All vaccine candidates based on AdVac® are produced using Crucell's PER.C6® production technology.

About PER.C6® technology

Crucell's PER.C6® technology is a cell line developed for the large-scale manufacture of biopharmaceutical products including vaccines. The production scale potential of the PER.C6® cell line has been demonstrated in an unprecedented successful bioreactor run of 20,000 liters. Compared to conventional production technologies, the strengths of the PER.C6® technology lie in its excellent safety profile, scalability and productivity under serum-free culture conditions. These characteristics, combined with its ability to support the growth of both human and animal viruses, make PER.C6® technology the biopharmaceutical production technology of choice for Crucell's current and potential pharmaceutical and biotechnology partners.
