Transgene SA (Paris:TNG) (Euronext Paris: FR0005175080), a biopharmaceutical company that develops targeted immunotherapy products to treat major unmet medical needs in cancer and chronic infectious diseases, announced pre-clinical data obtained with its novel immunotherapeutic, TG1050, to treat chronic hepatitis B infection (CHB). These results were presented in an oral session (Hepatitis B and D Experimental) at this year's European Association for the Study of the Liver Conference (Amsterdam, Netherlands, April 24-28, 2013).
Philippe Archinard, Chairman and Chief Executive Officer of Transgene, stated: "We are excited that TG1050 was selected for an oral presentation at EASL. We hope that this presentation will trigger interest in the scientific community as well as discussions with potential partners. We expect to start a first-in-human/phase 1 clinical trial in 2014 and we believe that TG1050 is currently the most promising direct active immunotherapeutic in development for the treatment of CHB, an area of unmet medical need and high worldwide prevalence."
The selection process from 32 promising product candidates of TG1050 was endorsed and approved by different panels of key opinion leaders in the viral hepatitis field. TG1050 is based on a non-replicative Adenovirus 5 vector that encodes three HBV (Hepatitis B Virus) antigens or related domains. The clinical candidate has demonstrated potent immunogenicity in pre-clinical mouse models as well as genetic stability. Immunogenic properties include induction of potent, multi-specific, functional and cross-reactive T cell responses, including both cytokines production (IFNγ/TNFα) and in vivo cytolysis; all important characteristics that have been associated with viral clearance during natural infection.
