Paris (France), March 25, 2019 – 6.00 pm CET – Onxeo S.A. (Euronext Paris, NASDAQ Copenhagen: ONXEO), (“Onxeo” or “the Company”), a clinical-stage biotechnology company specializing in the development of innovative drugs targeting tumor DNA Damage response (DDR) in oncology, in particular against rare or resistant cancers, today provides details on the presentation of data from five studies supporting the company’s lead drug candidate, AsiDNA™, in poster sessions at the upcoming American Association for Cancer Research (AACR) Annual Meeting being held March 29 – April 3, 2019, in Atlanta, GA, USA.

Françoise Bono, PhD, Chief Scientific Officer, commented: “We are very pleased to have five studies accepted and presented at the prominent AACR meeting as it reflects the interest, the quality and the diversity of our current translational research on AsiDNA™. Through these data, we further demonstrate the uniqueness of our lead compound in terms of mechanism of action and its related unique properties, especially on preventing the occurrence of resistance to treatment, one of the major issues in oncology today. All these data complement and reinforce our rationale for the continued clinical development of AsiDNA™ expected to start in the coming weeks, now that we have identified the active doses that trigger target engagement and confirmed the favorable safety profile in our phase I DRIIV study. We look forward to presenting and discussing our very exciting findings during the conference.”
