VIVALIS: GSK and Kaketsuken Will Co-Develop EB66 Cell Based Flu Vaccines

NANTES, FRANCE--(Marketwire - September 29, 2009) - VIVALIS (NYSE Euronext Paris: VLS), announces today that its partners GlaxoSmithKline K.K. (Head Office: Shibuya-ku, Tokyo, President: Marc Dunoyer, hereinafter referred to as GSK), GlaxoSmithKline Biologicals (Belgium), its licensee of EB66® cell line for the production of flu vaccine, and The Chemo-Sero-Therapeutic Research Institute (Head Office: Kumamoto-shi, Kumamoto, Director General: Akinobu Funatsu, hereinafter referred to as "Kaketsuken"), have signed an agreement to co-develop influenza vaccines, including pandemic influenza vaccines, produced using EB66® cell-culture technology in Japan.

The agreement aims to integrate cell-culture technology and know-how owned by or licensed to GSK and Kaketsuken (including the EB66® cell line in- licensed by GSK from Vivalis) with GSK's adjuvant technology in order to co- develop, manufacture and supply a cell-culture based pandemic influenza vaccine as early as possible in Japan.

With this collaboration, GSK and Kaketsuken are committed to contributing to Japan's pandemic plan through developing and making available as quickly as possible a cell-culture based pandemic influenza vaccine to as many people as possible in need of this vaccine.

GSK has extensive experience and a track record in manufacturing and supplying influenza vaccines as well as in adjuvant technology. From GSK's experience with an H5N1 pandemic influenza vaccine in Europe, using GSK's adjuvant promotes stronger and longer immune response. Thus, influenza vaccines that use the adjuvant are expected to induce high immune response against the virus even at a low dose of antigen, sparing the amount of antigen required per vaccination. Furthermore, the addition of the adjuvant has demonstrated to stimulate an immune response even if the influenza strain changes slightly (drifts), providing a substantial level of cross- protection. Also, the safety of the adjuvant has been confirmed by large- scale clinical trials.

Marc Dunoyer, president of GSK said, "This agreement with Kaketsuken, a leader in research and manufacturing of vaccines in Japan, is an extremely important milestone in developing and providing a stable supply of vaccines necessary to combat pandemic influenza. This collaboration is a good example that reflects the policy of the Vaccine Industry Vision, which refers to the collaboration between domestic makers and foreign-affiliated companies, and this project has been submitted for the Health Labour Sciences Research Grant for research and development of a cell culture based pandemic influenza vaccine, as a joint project between a foreign and domestic company. I am pleased that we will be able to actively contribute to influenza measures in Japan in this way."

Kaketsuken has been fulfilling its responsibilities of supplying seasonal influenza vaccines in Japan over the years and as a part of the country's pandemic response plan, it is manufacturing pandemic vaccine solutions for H5N1, contributing to the government's stockpiling. It is also currently manufacturing vaccines for the swine-derived H1N1 influenza that continues to spread.

GlaxoSmithKline continues to be committed to doing all it can to support governments and health authorities around the world in planning to respond to a global influenza pandemic, both ahead of an outbreak and once it has officially been declared. GSK has made substantial progress in its vaccine development programme and continues to investigate ways to further improve its pre-pandemic and pandemic vaccine strategies. To this end more than $2 billion has already been invested in developing a vaccine to combat H5N1 influenza, increasing the production capacity for influenza vaccines and its antiviral flu treatment Relenza® (zanamivir hydrate), in addition to ensuring the continuity of critical business operations and processes.

Franck Grimaud, CEO and Majid Mehtali, CSO, co-managers of VIVALIS said: "VIVALIS is very pleased of this agreement between GSK and Kaketsuken in the flu field. It is a further evidence that the EB66® vaccine production technology should establish its position as a new global industry standard in the coming years in the vaccine field. In the current environment, the risk of a flu pandemic has increased the determination of public authorities and manufacturers in possessing a technology offering more rapid, effective and safer performances."

About the EB66® 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 to high cell densities in suspension in a serum-free medium (>20 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® cell line is currently used or being tested by 75% of the major players in vaccines. VIVALIS has furthermore demonstrated that the EB66® cell line can be easily genetically modified, permitting the expression of recombinant proteins of potential interest. Moreover the glycosylation profile of monoclonal antibodies produced through EB66® cell lines is similar to the glycosylation profiles of human monoclonal antibodies with the added benefit of being distinguished by reduced fucose content. This latter characteristic is known to be associated with a higher level of antibody cytotoxic activity, particularly useful in the treatment of cancer cells.
