Onxeo announces allowance of U.S. patent for Livatag® in hepatocellular carcinoma

USPTO Notice of Allowance received for patent related to specific route of administration for Livatag® provides protection of related claims until 2032


Paris (France), May 10, 2017 – 6.30 pm CEST – Onxeo S.A. (Euronext Paris, NASDAQ Copenhagen: ONXEO), a clinical-stage biotechnology company specializing in the development of innovative drugs for the treatment of orphan diseases, in particular in oncology, today announced that it has received a Notice of Allowance from the U.S. Patent and Trademark Office for a patent application covering the specific route of administration for Livatag®, which is currently in a phase III clinical trial (ReLive) for the second-line treatment of hepatocellular carcinoma (primary liver cancer).

Livatag® (doxorubicin Transdrug™) is based on an innovative technology allowing the formulation of doxorubicin (a chemotherapeutic agent) within nanoparticles composed of polyalkylcyanoacrylate, cyclodextrin, and poloxamer. This nanoparticle formulation provides new and promising properties, including overcoming the mechanisms of chemoresistance developed by tumor cells that affect the efficacy of chemotherapy agents.

“The United States represents a significant target market for Livatag®. This new U.S. patent significantly strengthens our Livatag® intellectual property portfolio, and enhances the value of this late-stage product candidate. We look forward to the availability of data from our ReLive trial in mid-2017,” said Judith Greciet, CEO of Onxeo.

The new patent provides protection of the associated claims in the U.S. until 2032, and is in addition to the previously issued patents for the same patent family in other major territories, such as Europe and Japan. An additional patent family has also been filed based on a specific composition of Livatag® nanoparticles that, if granted, would extend the patent protection of Livatag® to 2036.
