Vical’s DNA Vaccine Technology Addresses Challenges of Emerging Diseases

November 10, 2009: 06:30 AM ET – money.cnn.com

GALVESTON, Texas, Nov. 10, 2009 (GLOBE NEWSWIRE) — Vical Incorporated (Nasdaq:VICL) today is presenting a strong rationale advocating the use of DNA vaccine technology for emerging and/or pandemic infectious diseases. At the University of Texas Medical Branch Symposium, “The Changing Landscape of Vaccine Development,” Larry R. Smith, Ph.D., the company’s Vice President of Vaccine Research, systematically outlined the advantages of DNA vaccine technology over conventional vaccine technology in dealing with serious emerging threats.

Dr. Smith’s presentation, “DNA Vaccines: Rapid Response to Pandemic Outbreaks,” highlights historical data from multiple human clinical trials of DNA vaccines demonstrating safety, broad immunogenicity, and initial indications of efficacy. A favorable safety profile has been established through testing of various DNA vaccines in human subjects now totaling in the thousands. Recent studies of DNA vaccines formulated with Vical’s Vaxfectin(R) adjuvant or polaxamers have shown clear ability to elicit both antibody and T-cell immune response. These advantages, coupled with rapid development speed, excellent flexibility, and manufacturing which is not dependent upon cell culture or chicken eggs, encourage the use of DNA vaccine technology for emerging threats such as the recent H1N1 swine flu and other emerging diseases.

As previously announced, Vical was the first company to produce a vaccine candidate against A/H1N1 pandemic influenza (swine flu) after the initial reports of widespread outbreaks in Mexico, and the first to announce robust immunogenicity results from animal testing in two species. The U.S. Navy has awarded a contract for $1.25 million to support preparations for a Phase 1 clinical trial of the company’s H1 vaccine to be conducted in collaboration with the U.S. Naval Medical Research Center (NMRC), a biomedical research organization within the Navy.

About Vical

Vical researches and develops biopharmaceutical products based on its patented DNA delivery technologies for the prevention and treatment of serious or life-threatening diseases. Potential applications of the company’s DNA delivery technology include DNA vaccines for infectious diseases or cancer, in which the expressed protein is an immunogen; cancer immunotherapeutics, in which the expressed protein is an immune system stimulant; and cardiovascular therapies, in which the expressed protein is an angiogenic growth factor. The company is developing certain infectious disease vaccines and cancer therapeutics internally. In addition, the company collaborates with major pharmaceutical companies and biotechnology companies that give it access to complementary technologies or greater resources. These strategic partnerships provide the company with mutually beneficial opportunities to expand its product pipeline and address significant unmet medical needs.

San Diego Companies Pioneer ‘DNA Vaccines’

By Tom Fudge

September 23, 2009 – www.kpbs.org/

SAN DIEGO — Two San Diego companies are getting a lot of attention from the world of medicine and from investors. They’re doing it with a new kind of vaccine.

The conventional vaccine for swine flu should arrive next month and doctors expect it to be a good match for the H1N1 virus. Even so, two San Diego companies making alternative flu vaccines have seen their stock prices increase dramatically. The companies, Vical and Inovio, have shown good results in animal testing .

DNA vaccines use genetic sequencing to create a harmless, mock virus that gets an immune response. Joseph Kim, CEO of Inovio, said the conventional swine flu vaccines might work fine. But not if the virus mutates.

“That’s where we come in,” he said. “Our vaccine is specifically designed to work against a changing strain of virus.”

Neither company has FDA approval. But they say making DNA vaccines is faster, safer and the way of the future.
