Transgene SA (Paris:TNG) (Euronext Paris: FR0005175080), a biopharmaceutical company that develops targeted immunotherapy products to treat major unmet medical needs in cancer and infectious diseases, today announced that favourable pre-clinical and clinical data on two Transgene products - TG1050 and TG4040 to treat chronic hepatitis B (CHB) and chronic hepatitis C (CHC), respectively - will be presented in oral presentations at this year's European Association for the Study of the Liver (EASL) Conference (Amsterdam, Netherlands, April 24-28, 2013). The full abstracts are available at http://www.easl.eu.
"We are delighted to have the opportunity to present data at EASL, Europe's largest liver conference. TG1050 is a novel immunotherapeutic to treat CHB that has shown very promising preclinical results and will soon be moving to early clinical development" stated Philippe Archinard, Chairman and CEO of Transgene. He added: "In addition to the preclinical proof-of-concept data published in September 2012, we have today released supplementary information, obtained in pre-clinical naïve and HBV murine models, on the immunogenicity of TG1050 and its capacity to induce long-term T cell response. This evidence further underlines our belief in the product's potential to become an important new first in class immunotherapeutic to treat CHB, an area of unmet medical need."
"TG4040 has recently completed successful phase 2 trial in patients with CHC" stated Nathalie Adda, Chief Medical Officer of Transgene. She added: "Following interim data published in April last year for TG4040 in combination with PegIFNα2a and ribavirin, we report the final results of the phase 2 HCVac trial with sustained viral response at 24 weeks (SVR24) and additional immunogenicity, specific T-cell and humoral responses. The study has demonstrated that pre-treatment with TG4040 has a positive impact on viral response as shown by cEVR and SVR improvement compared to PegIFN alpha 2a and Ribavirin alone. HCV Immunotherapy now could be explored in combination with an IFN-free DAA regimen."
The oral presentations will take place on Friday, April 26 and Saturday, April 27, 2013.
