Vical and AnGes Announce Collaboration to Develop Therapy for Ebola Virus Disease

SAN DIEGO and TOKYO, Jan. 14, 2015 (GLOBE NEWSWIRE) -- Vical Incorporated (Nasdaq:VICL) and AnGes MG (Tokyo:4563) announced today that they have entered into collaboration to develop and commercialize an equine polyclonal antibody therapy for patients afflicted with Ebola virus disease. No medicines or vaccines are currently approved for the treatment of Ebola.

Unlike prophylactic vaccines, which require widespread vaccinations, multiple doses and time in order to mount a protective immune response prior to exposure, polyclonal antibody therapy offers a more targeted approach of providing immediate immune globulin as a treatment against Ebola virus. Therapeutic approaches utilizing equine polyclonal antibodies have been used for the treatment of viral diseases such as rabies, bacterial toxins such as tetanus and diphtheria, as well as black widow spider venom.

The planned approach will be to isolate antibodies from the horses immunized with a DNA vaccine encoding an Ebola virus glycoprotein antigen. The antibodies will be purified and developed for the treatment of Ebola virus disease in humans.

Under the agreement, Vical will develop and provide to AnGes a DNA vaccine encoding the glycoprotein antigen of the 2014 Zaire strain of Ebola virus, formulated with Vical's proprietary Vaxfectin® adjuvant. AnGes will receive the right to exclusively develop and commercialize the equine polyclonal antibody therapy in Japan and will be responsible for all development costs. Vical will receive an upfront payment and is eligible to receive royalties on net sales and a percentage of payments received by AnGes under any sub-licensing agreements.

"We are pleased to have the opportunity to contribute Vical's resources and capabilities to the global fight against Ebola," said Larry R. Smith, Ph.D., Vical's Vice President of Vaccine Research. "Therapeutic interventions may be the best near-term solution for dealing with the Ebola epidemic. And historical use of polyclonal antibodies bodes well for this approach."

"We believe that the equine polyclonal antibody therapy can contribute to the measures against Ebola in Japan," said Ei Yamada, Ph.D., President and CEO of AnGes. "Thanks to Vical, we will soon start an initial study in Japan for the purpose of collecting data and optimizing the production process."
