STRASBOURG, France--(BUSINESS WIRE)--Regulatory News:

Transgene (Paris:TNG) (Euronext Paris: TNG), a company focused on designing and developing targeted immunotherapies for the treatment of cancer and infectious diseases, today presented a poster on TG1050 preclinical results at the AASLD (American Association for the Study of Liver Diseases) Liver Meeting 2016, Boston (MA). TG1050 is a therapeutic vaccine for the treatment of chronic hepatitis B (or HBV1 infection).

The abstract published in Hepatology can be downloaded on the AASLD website (DOI: 10.1002/hep.28800). The poster is available on Transgene’s website.

Poster title: TG1050, an HBV-targeted immunotherapeutics, efficiently decreases HBV viremia and antigenemia in a preclinical model; a meta-analysis and the determination of the involvement of CD4 and CD8 T cells.

The poster shows a meta-analysis of preclinical data obtained with TG1050 in HBV persistent mice and preliminary data on the mode of action of TG1050.

Transgene scientists showed:

  • A significant treatment effect on viremia and HBsAg (surface antigen of the hepatitis B virus) levels and a higher percentage of responders for viremia and HBsAg in TG1050-treated mice;
  • That the period needed to observe a decrease in viral parameters is shorter in TG1050-treated mice;
  • That some mice treated by TG1050 displayed anti-HBsAg antibody seroconversion (clinical goal of HBV therapies);
  • The involvement of TG1050-induced HBV-specific CD8 and CD4 T cell responses in TG1050 antiviral effects.

Transgene is currently conducting a Phase 1/1b clinical study evaluating the safety and tolerability of TG1050 in patients who are currently being treated for chronic HBV infection with standard-of-care antiviral therapy.

About TG1050

TG1050 is a targeted immunotherapy candidate for the treatment of chronic hepatitis B, based on a viral vector expressing 3 HBV antigens. Transgene has initiated a randomized, multi-center, double-blind, placebo-controlled safety and dose-finding first-in-man Phase 1 study (NCT02428400) evaluating the safety and tolerability of TG1050 in patients who are currently being treated for chronic HBV infection with standard-of-care antiviral therapy. The technology of TG1050 is also being developed in China, where it is currently under SFDA evaluation and has been recently granted an IND number. In China, Transgene operates a joint-venture with Tasly Biopharmaceutical Technology.
