Valneva Announces the First Ever Marketing Approval in Europe for a Vaccine Produced in the EB66® Cell Line

Lyon (France), May 19, 2014 - European biotechnology company Valneva SE (Valneva) announced today the first ever marketing approval in Europe for a vaccine produced in the EB66® cell line. The marketing authorization was granted by the European Medicines Agency (EMA) for the prevention of Muscovy Duck Parvovirus (MDPV).

MDPV is a contagious disease which causes high morbidity and mortality in one to three weeks-old ducklings and is a well-recognized hazard of commercial duck production. The disease, which has been reported from all major duck farming countries in Europe and other countries including the former Soviet Union, Israel, China, Vietnam and Japan, remains a serious problem in countries where Muscovy ducks are farmed intensively.

Thomas Lingelbach, President and Chief Executive Officer and Franck Grimaud, President and Chief Business Officer of Valneva, commented "This approval is an important milestone for Valneva as the European Medicines Agency has now validated the use of the EB66® cell line in vaccines. It is also the third marketing approval worldwide since the beginning of the year for a vaccine produced in the EB66® cell line."

Valneva licensed the marketing of the MDPV product to Merial. Financial terms of the agreement were not disclosed but do include milestone payments and royalties on net sales of the product, which the Company expects from 2015 onwards.


To date, Valneva has more than 35 license agreements with the world's largest pharmaceutical companies for the use of its EB66® cell line technology in both human and animal health vaccines. In March 2014, Valneva announced the marketing approval in Japan of a pandemic H5N1 influenza vaccine produced in the EB66® cell line and the marketing approval in South America of an EB66®-based vaccine for the prevention of inclusion body hepatitis virus (IBH).

About the EB66® Cell Line

Valneva's EB66® cell line is a highly efficient platform for vaccine production. It is derived from duck embryonic stem cells and today represents a compelling alternative to the use of chicken eggs for large scale manufacturing of human and veterinary vaccines. To date, Valneva has more than 35 research and commercial agreements with the world's largest pharmaceutical companies to utilize its EB66® technology. The first veterinary vaccine using EB66® technology received market approval in 2012 and a new drug application (NDA) for human pandemic influenza is currently under review in Japan.
