Vical Licenses Vaxfectin(R) Adjuvant to Cyvax for Use in Malaria Vaccines

12/05/2012


SAN DIEGO, Dec. 5, 2012 (GLOBE NEWSWIRE) -- Vical Incorporated (Nasdaq:VICL) announced today a worldwide, nonexclusive license of its patented Vaxfectin® adjuvant to Cyvax, Inc., a privately held vaccine development company, for use in malaria vaccines. Financial terms of the agreement were not disclosed.

Vijay B. Samant, Vical's President and Chief Executive Officer, said, "We are pleased to expand our Vaxfectin® franchise with the license to Cyvax for malaria vaccines after entering into the initial Vaxfectin® license with Bristol-Myers Squibb for antibody production in the prior quarter. Vaxfectin® has an expansive range of potential applications as reflected by the scope of these licenses." Cyvax's Chief Executive Officer, Jonathan Markham, said, "After conducting a significant body of pre-clinical work, Cyvax elected to move forward with Vical's Vaxfectin® due to the robust enhancement in efficacy we observed with that adjuvant. The Vaxfectin® adjuvant also offers comparative advantages across a number of other important domains including safety, tolerability, and commercial scalability."

About Vaxfectin®

Vaxfectin® is a novel adjuvant discovered through extensive screening of Vical's lipid portfolio, and represents the best-performing among this new class of adjuvants. A growing library of research supports its broad utility with a variety of infectious disease and cancer applications. Vaxfectin® has been shown in multiple animal models to significantly increase the antibody and T-cell immune responses to antigens expressed from DNA vaccines. Vaxfectin® has achieved similar effects with protein-based vaccines for infectious diseases and with tumor-associated antigen peptides for cancer. Three Phase 1 clinical trials of Vaxfectin®-formulated vaccines against pandemic strains of influenza extended the immunogenicity results to humans, and demonstrated favorable safety and tolerability. Vical is developing Vaxfectin®-formulated vaccines including CyMVectin™, a prophylactic DNA vaccine against cytomegalovirus (CMV), and a therapeutic DNA vaccine against herpes simplex virus type 2 (HSV-2).
