NANTES, FRANCE--(Marketwire - June 15, 2010) - VIVALIS (NYSE Euronext: VLS), a biopharmaceutical company, announced today that it has signed a commercial license with an undisclosed animal health company to use the EB66® cell line, proprietary of VIVALIS, for the production of veterinary vaccines. This commercial license is VIVALIS' sixth commercial license signed to date in the veterinary vaccine field. It brings the total number of commercial licenses of the EB66® cell line technology signed for the production of vaccines or therapeutic proteins to 17.

Terms of the agreement were not disclosed

"We are very pleased to convert another research license into a new commercial agreement within the animal vaccine field, increasing penetration of the EB66® cell line in this fast developing market. This new license again confirms that the EB66® cell platform is a reference cell substrate for the industrial manufacture of viral vaccines. It also confirms our analysis that an increasing number of vaccine companies are moving away from chicken eggs to adopt the EB66® cell platform as their standard production platform. With many advanced discussions with pharmaceutical and biotechnology companies both for vaccine and protein productions, we are confident that 2010 will be another dynamic year for EB66® licensing with the renewed objective to sign 7 new licenses this year of which 2 commercial licenses", said Franck Grimaud, CEO, and Majid Mehtali, CSO, co-managers of VIVALIS.

About the EB66® cell line

The EB66® cell line, derived from duck embryonic stem cells, presents unique industrial and regulatory characteristics, such as long-term genetic stability, immortality and cell growth up to high cell densities in suspension in a serum-free medium ( > 40 millions cells/mL).

The BMF (Biologics Master File) for the registration of the EB66® cell line with the FDA (U.S. Food and Drug Administration) was filed on June 27, 2008.

The EB66® cells replicate a wide range of human and animal viruses and are currently used or being evaluated for the production of viral vaccines by the major players in vaccines.

The EB66® cells are easily genetically engineered to efficiently express recombinant proteins of interest ( > 1 g/l). Monoclonal antibodies produced in EB66® cells have human-like glycosylation profile, with the remarkable additional feature of having reduced fucose content. This latter characteristic provides a better cytotoxic activity to antibodies, particularly useful in the treatment of cancer cells.


VIVALIS (Euronext code: VLS) is a biopharmaceutical company that provides innovative cell-based solutions to the pharmaceutical industry for the manufacture of vaccines and proteins, and develops drugs for the prevention and treatment of viral diseases.
