Anti-Cocaine Vaccine Combined with Immunovaccine's DepoVax™ Shows Promise in Exploratory Study

DepoVax Platform Induces Antibodies that Block Cocaine Entry to Brain

Halifax, Nova Scotia; October 24, 2012 – Immunovaccine Inc. ("Immunovaccine" or the "Company") (TSX-V: IMV), a clinical stage vaccine company, today announced positive results from a preliminary study of an anti-cocaine vaccine in collaboration with Weill Cornell Medical College.  The vaccine, which added Immunovaccine's DepoVax™ adjuvanting technology to Weill Cornell's novel anti-cocaine vaccine (dAd5GNE), was being evaluated in rodents for its ability to produce antibodies capable of blocking cocaine from being delivered to the brain in an effort to prevent its physiological effect. 

The study showed that the DepoVax-enhanced vaccine produced high levels of target antibodies that were able to sequester cocaine in the blood of immunized mice and block its delivery to the brain.  Immunovaccine hopes to build on this interesting proof of concept work and is currently evaluating opportunities to further develop the program.  Further potential studies would aim to confirm these results and explore the duration of immunity produced by the vaccine.  There are research efforts to develop an anti-cocaine vaccine that is able to effectively induce and maintain a sufficient immune response without requiring frequent immunizations. 

"Immunovaccine's delivery system holds the vaccine at the site of injection allowing the immune system to process the vaccine differently than other vaccines," said Dr. Marc Mansour, the company's chief science officer.  "This results in strong immunity against the target, in this case cocaine. The next time cocaine appears in the blood the subject's immune system seizes the molecules and neutralizes their effect." 

In March 2012, Immunovaccine and Weill Cornell announced a research agreement to explore the company's technology with a vaccine being developed for treating cocaine addiction. The project builds on earlier cocaine vaccine work, funded by the National Institute on Drug Abuse (NIDA) of the National Institutes of Health (NIH), at Weill Cornell. The goal of this particular study was to evaluate the ability DepoVax™ to trigger a strong immune response with Weill Cornell's dAd5GNE vaccine.  There currently are no anti-cocaine vaccines approved by the United States Food and Drug Administration (FDA). 

Cocaine abuse is estimated to affect approximately 4.8 million Americans annually with an additional one million Americans using crack cocaine at least once each year.  A safe and effective anti-cocaine vaccine has the potential to significantly address the healthcare and societal problem associated with cocaine abuse and addiction.
