|Novavax reports positive preclinical results on its novel vaccine for pandemic influenza|
|NASDAQ symbol: NVAX|
MALVERN, PA, Aug 25, 2005 /PRNewswire-FirstCall via COMTEX/ -- Novavax, Inc. (Nasdaq: NVAX), a specialty biopharmaceutical company, today reported preclinical results on the Company's novel Virus-Like Particle (VLP) influenza vaccine. Novavax's biological group led by Dr. Gale Smith, together with Dr. Tumpey and Dr. Bu from the Centers for Disease Control and Prevention, published the detailed results in the August 15 online edition of the journal Vaccine. The study demonstrates that a H9N2 influenza virus (avian flu) vaccine produced with the Company's proprietary VLP technology is effective in protecting animals when challenged with live H9N2 influenza virus.
"Our VLP technology, based on a scalable process with short production lead times, offers an attractive alternative to the existing egg-dependent and the newer cell-based methods for the manufacture of influenza vaccine and other urgently needed vaccines. These advantages address the challenge of producing large quantities of a pandemic flu vaccine within a short timeframe," said Rahul Singhvi, President and CEO of Novavax. "This publication demonstrates the value of Novavax's VLP vaccine pipeline. Our plan is to advance our VLP technology into clinical trials with both pandemic and seasonal versions of influenza VLP vaccines."
The work, published in the peer-reviewed journal Vaccine, was completed in collaboration with the Center for Disease Control and Prevention. It involved VLP vaccines constructed from proteins (HA, NA, and M1) produced from genes cloned from avian H9N2 influenza virus by Novavax at the CDC. The animals, vaccinated with a low dose of VLP without the addition of an adjuvant, developed antibodies after the first subcutaneous immunization. Immune responses increased after booster inoculation, and were shown to be protective when challenged with the H9N2 influenza virus.

"VLP vaccines depend on human immune mechanisms which are highly effective at recognizing and mounting a response against particles the general size and structure of viruses. The nanometer size and structural similarity of VLP vaccines to a live virus enable efficient interaction at a cellular level. VLP vaccines safely imitate whole virus vaccines and can never cause infection since they do not contain genetic material from a virus. Our VLP vaccines for flu, HIV/AIDS and other diseases are proving to be effective at stimulating immunity even at low doses and without the addition of chemical adjuvants," said Dr. Gale Smith, Vice President Vaccine Development of Novavax.
The study was supported in part by a grant from the National Institute of Allergy and Infectious Disease (NIAID) of the National Institutes of Health (NIH) to develop avian flu vaccines using VLP technology. The Company expects to continue working on its Avian Flu vaccine program and produce vaccine for testing in human clinical trials. Significant progress is also being made with VLP vaccines for AIDS and SARS with the support of grants from the NIH.
About Avian Flu Viruses
Avian flu viruses are gaining worldwide attention as a strain of the virus has spread in migratory birds throughout most of Asia and Russia causing millions of birds to die from infection. Concern is growing of a potential pandemic if the virus was to become easily transmitted from human to human. There is no means to predict which specific strain of avian flu will prove capable of human to human transmission. For this reason new vaccine production methods that are rapid, not dependent on limited supplies of fertilized eggs, and ideally effective at standard doses are needed to assist health authorities in meeting the challenge of the demand for a pandemic vaccine.
About Virus-Like Particle (VLP) Technology
Novavax's VLP technology uses recombinant protein technology to imitate the important three dimensional structures of the influenza virus to provide protection without the risk of infection or disease and without the addition of chemical adjuvants. Novavax's proprietary production technology lowers the cost and eliminates the labor intensive nature of the traditional egg based process by using insect cells. The VLP technology produces safe and effective vaccine products through an aseptic process that reduces contamination risk and produces high, cost-effective yields. A key advantage of the technology is the ability to rapidly respond to emerging threats or new strains. A VLP vaccine can be engineered within a few weeks of the discovery of a new virus, after the publication of its DNA sequence data by the government. VLP vaccines can be manufactured within a three day production process in an insect cell system widely used in the biotechnology industry.
