Independent Development Program Highlights

-- Preliminary data from a Phase 1 trial of the company's Vaxfectin(R)-formulated H5N1 pandemic influenza DNA vaccines demonstrated for the first time that DNA vaccines have achieved potentially protective levels of antibody responses in humans with no significant safety issues. These results support further development of pandemic influenza DNA vaccines and advancement of additional Vaxfectin(R)-formulated DNA vaccines. The Vaxfectin(R) adjuvant is currently being evaluated by potential partners for a variety of additional vaccine applications.

-- In June, Vical received $6.3 million of cash payments and equity investments from AnGes MG, Inc., for continued funding of the company's ongoing Allovectin-7(R) Phase 3 metastatic melanoma trial. Vical is conducting the Phase 3 pivotal trial multinationally at nearly 50 sites to evaluate Allovectin-7(R) as first-line therapy in chemotherapy-naive patients with Stage III or IV metastatic melanoma.

-- In an editorial commentary in the June 15 issue of The Journal of Infectious Diseases, independent experts on cytomegalovirus (CMV) said the vaccine under development by Vical, at the optimal dose and regimen tested, "holds promise" based on its ability to elicit persistent immune responses in a majority of CMV-seronegative subjects, and warrants further evaluation for its potential to prevent infection and disease. The commentary accompanied the issue's lead article, which expanded on previously reported immunogenicity data from a Phase 1 study of Vical's DNA vaccine. The company's Phase 2 trial of the CMV vaccine in patients undergoing hematopoietic cell transplants is on schedule for release of interim efficacy data in the second half of 2008.

-- The company successfully completed first-year milestones under a three-year, $6.0 million grant awarded in 2007, and is advancing with the development of the RapidResponse(TM) DNA vaccine manufacturing process, which is designed to allow extremely rapid and large-scale production of DNA vaccines with low capital requirements.

Partnered Development Program Highlights

-- In July, Vical received a $1.0 million cash payment from its Japanese partner, the biotechnology company AnGes MG, Inc., reflecting continued progress of its Collategene(TM) angiogenesis program. Vical received an initial upfront payment of $1.0 million under an exclusive license agreement in 2005, and further advancement may lead to additional milestones and royalty payments. In March 2008, AnGes filed for marketing approval with the Japanese Ministry of Health, Labor and Welfare for the use of Collategene(TM) as a treatment for critical limb ischemia, an advanced form of peripheral arterial disease, and for Buerger's disease. The Collategene(TM) application in Japan is the first for an angiogenesis product based on Vical's patented DNA delivery technology.

-- The company's European partner sanofi-aventis is conducting a 500-patient Phase 3 pivotal trial of its fibroblast growth factor 1 (FGF-1) angiogenesis product candidate in key global markets and anticipates filing for marketing approvals in 2010.
