Vical Presents Encouraging Preliminary Data From Final 12-month Follow-up in TransVax(TM) CMV Vaccine Phase 2 Transplant Recipient Trial

Vical Incorporated announced that the company's TransVax(TM) cytomegalovirus (CMV) vaccine elicited sustained increases in both cellular and antibody immune responses compared with placebo through the final 12-month follow-up in an ongoing Phase 2 trial in hematopoietic cell transplant (HCT) recipients

SAN DIEGO, CA, USA | April 22, 2010 | Vical Incorporated (Nasdaq:VICL - News) announced today that the company's TransVax(TM) cytomegalovirus (CMV) vaccine elicited sustained increases in both cellular and antibody immune responses compared with placebo through the final 12-month follow-up in an ongoing Phase 2 trial in hematopoietic cell transplant (HCT) recipients. Richard T. Kenney, M.D., Vical's Vice President of Clinical Development, is presenting the encouraging preliminary data today at the World Vaccine Congress (Washington -- April 19-22).

"We were excited to see that our TransVax(TM) vaccine was able to enhance both T-cell and antibody responses to the encoded CMV antigens through the final 12-month data point," said Dr. Kenney, "and we are excited to see how these responses impact viral control. We also saw an encouraging boost in both T-cell and antibody responses after the fourth injection, which could prove important in controlling late-onset CMV reactivation. We expect to complete our analysis of the final trial data and report on our full evaluation of viral load and clinical endpoints in the third quarter."

About TransVax(TM)

TransVax(TM) is a bivalent DNA vaccine containing plasmids (closed loops of DNA) encoding CMV phosphoprotein 65 (pp65) and glycoprotein B (gB) for induction of cellular and humoral immune responses. TransVax(TM) is formulated with a proprietary poloxamer-based delivery system. The Phase 2 trial is evaluating the potential for TransVax(TM) to prevent CMV reactivation in immunosuppressed CMV-seropositive hematopoietic stem cell transplant (HCT) recipients, which could reduce antiviral usage and CMV-associated disease. At the 12-month immunogenicity analysis by group, TransVax(TM) continued to provide increased cellular immunological responses to both encoded CMV antigens, and increased antibody responses to gB, compared with placebo. TransVax(TM) has received orphan drug designation for HCT and solid organ transplant patients.
