NANTES, FRANCE--(Marketwire - October 12, 2010) - VIVALIS (NYSE Euronext: VLS), a biopharmaceutical company, announced today that The Kitasato Institute, the vaccine co-leader in Japan, has signed a research license agreement to evaluate the replication of an undisclosed virus in VIVALIS' EB66® cell line for the manufacturing of human vaccines.

Terms of the agreement were not disclosed.

"We are very pleased to support Kitasato's continued commitment to deliver safer and higher quality vaccines. This new research license with one of the leading vaccine manufacturer in Japan is the third license or sublicense with leading vaccine Japanese companies signed in this country these last months. We are very happy that our EB66® cell line is gaining visibility in this very important market and receiving more recognition around the world. With six new EB66 licenses signed since the beginning of the year, we are convinced that we will reach the objective of seven new licenses before the end of 2010", said Franck Grimaud, CEO, and Majid Mehtali, CSO, co-managers of VIVALIS.

About The EB66® Cell Line

The EB66® cell line, derived from avian 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 using serum-free media ( > 40 million cells/mL).

EB66® cells replicate a wide range of human and animal viruses and are currently used for the production of investigational viral vaccines by many major vaccine developers.

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

EB66® cells are also easily engineered to express recombinant proteins of interest ( > 1.0 g/l). Monoclonal antibodies produced in EB66® cells have a human-like glycosylation profile with the additional benefits of reduced fucose content. This latter characteristic provides increased cytotoxic activity (ADCC) to antibodies, which may be useful in the treatment of cancer and infectious disease.


VIVALIS (Euronext: 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 unmet medical needs.
