Vical Reports First Quarter 2007 Financial Results; Highlights Progress in Key

Development Programs

SAN DIEGO, May 3 /PRNewswire-FirstCall/ -- Vical Incorporated (Nasdaq: VICL) today reported financial results for the quarter ended March 31, 2007. Revenues for the first quarter of 2007 were $1.3 million, compared with revenues of $5.6 million for the first quarter of 2006. The net loss for the first quarter of 2007 was $9.6 million, or $0.24 per share, compared with a net loss of $4.5 million, or $0.16 per share, for the first quarter of 2006. The increase in net loss reflected spending to advance the company's pandemic influenza vaccine program through preclinical testing and to advance its Allovectin-7(R) melanoma program into a Phase 3 pivotal trial, as well as a decrease in contract manufacturing and grant revenues.

The company's first quarter 2007 financial results are consistent with its projection for a full year net loss of between $32 million and $35 million and a net cash burn, excluding equity investments, of $27 million to $30 million. Vical had cash and investments of $91 million at March 31, 2007.

Significant Milestones in Cancer Programs

Merial Limited received conditional approval of a DNA vaccine designed to treat melanoma in dogs -- the first-ever U.S. approval of a therapeutic cancer vaccine. Vical's licensee, a joint venture of Merck & Co., Inc. and sanofi aventis, will distribute the vaccine initially through veterinary cancer specialists.

Vical began its Phase 3 pivotal Allovectin-7(R) Immunotherapeutic for Metastatic Melanoma (AIMM) trial in chemotherapy-naive patients with recurrent Stage III or IV disease. The trial was designed under a Special Protocol Assessment (SPA) with the U.S. Food and Drug Administration (FDA), and the trial cost is being funded through cash payments and equity investments by partner AnGes MG, Inc. The primary endpoint of the trial is objective response rate after 24 weeks or more.

Angiogenesis Partners Advancing toward Approvals

The company's licensee, AnGes MG, Inc., is conducting an interim efficacy evaluation in its Japanese Phase 3 angiogenesis trial in patients with advanced peripheral arterial disease (PAD). Positive data from patients already enrolled, which has been unblinded as each patient completes the treatment follow-up, could lead directly to a filing for accelerated marketing approval in Japan and initiation of a Phase 3 registration trial in the United States.

The sanofi aventis group, Vical's other angiogenesis licensee, plans to initiate a pivotal Phase 3 trial in the second quarter of 2007 in approximately 500 PAD patients in 32 countries with a goal of reducing the need for amputations. If the trial is successful, multinational filings for marketing approval are anticipated in 2009-2010.

Increasing Applications for Vaxfectin(TM) Adjuvant

The U.S. Navy agreed to explore the use of Vical's patented Vaxfectin(TM) adjuvant with experimental DNA vaccines against malaria.

Vical's patents cover the use of Vaxfectin(TM) with conventional vaccines as well as DNA vaccines. In a recently completed study in mice, a commercial seasonal influenza vaccine formulated with Vaxfectin(TM) generated up to 60-fold higher antibody responses than unformulated vaccine at the same dose and allowed a nearly 10-fold reduction in vaccine dose. Results from the study suggest that Vaxfectin(TM) has the potential to be used as a dose-sparing agent with conventional vaccines against seasonal or possibly pandemic influenza strains.

Vical anticipates initiation in the second half of 2007 of a Phase 1 trial with the company's Vaxfectin(TM)-formulated pandemic influenza DNA vaccine.

Upcoming Conferences

The company expects to present data from various research and development programs at a series of scientific conferences:

The 11th International Betaherpes Virus Workshop (Toulouse, France, May 13-17),

The DNA Vaccines 2007 conference (Malaga, Spain, May 23-25),

The annual meeting of the American Society of Gene Therapy (Seattle, May 30-June 3), and

The annual meeting of the American Society of Clinical Oncology (Chicago, June 1-5).

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.
