Valneva Announces Successful Generation of a Highly-purified Zika Vaccine Candidate Using its FDA-EMA Approved Japanese Encephalitis Platform

Valneva SE (“Valneva” or “the Company”), a leading pure play vaccine company, today announced that it successfully generated a highly purified inactivated vaccine candidate against the Zika virus (ZIKV). The candidate was developed using the same manufacturing platform as the Company’s Japanese encephalitis vaccine, a vaccine which has already been approved by the American (FDA, Health Canada), European (EMA) and other regulatory agencies and is today commercialized in the US, Europe, Canada, and other territories under the tradenames IXIARO®/ JESPECT®.

In response to the international health emergency declared by the World Health Organization (WHO), Valneva announced on February 2, 2016 the initiation of research work on Zika based on the Company´s Japanese Encephalitis (“JE”) vaccine which Valneva developed from bench to market.
The Company´s JE vaccine is a Purified, Inactivated Vaccine (“PIV”) based on an original technology which Valneva exclusively in-licensed from the Walter Reed Army Institute of Research (WRAIR) and others.

Health authorities, including WHO, have expressed a preference for the PIV approach over other vaccine technologies, such as live attenuated approaches, in the initial target product profile for emergency use. The emergency target population is expected to be women of child-bearing age, including those who may be pregnant. There is a theoretical risk that live attenuated or replication competent viral vaccines given to pregnant women may be capable of crossing the placenta and infecting the foetus, and for this reason, live vaccines are not recommended during pregnancy.
By working on a type of vaccine that the regulatory agencies have seen and licensed before, Valneva believes that regulatory risk can be mitigated, resulting in the most efficient path to market.

Generated on the IXIARO® (JESPECT®) platform, Valneva’s Zika vaccine candidate demonstrated excellent purity and overall had a biological, chemical and physical profile comparable to the commercially produced JE vaccine.
Given the manufacturing process proximity, Valneva´s Zika vaccine candidate could be produced rapidly and at attractive costs in the clinical and commercial JE vaccine facilities. 2/3

Thomas Lingelbach, President and CEO and Franck Grimaud, Deputy CEO of Valneva, commented “We are glad that by building on our proven technology and leveraging on our strong capabilities in arthropod-borne flaviviruses, we have been able to generate a Zika vaccine candidate quickly. Valneva´s existing manufacturing platform represents a unique asset that could enable rapid production of a significant number of doses for an emergency use”.
Valneva was recently invited to participate to the global consultation on research related to Zika virus infection convened by WHO in Geneva and conducted discussions with WHO, BARDA and WRAIR to potentially join forces in accelerating the Zika vaccine development. Subject to regulatory approvals, Valneva could be in a position to move into clinical investigations in the coming months.

Valneva’s Japanese encephalitis vaccine is indicated for active immunization for the prevention of Japanese encephalitis for adults who travel to, or live in, endemic areas. It has received marketing approval in the U.S., Europe, Canada, Hong Kong, Singapore, and Israel under the trade name IXIARO® and in Australia and New Zealand where it is marketed as JESPECT®. It is the only vaccine being marketed to the U.S. military for Japanese encephalitis. IXIARO® is approved for use in individuals 2 months of age and older in the US and EU member states, Norway, Liechtenstein, Iceland, Singapore, Hong Kong and Israel. In all other licensed territories, IXIARO®/JESPECT® is indicated for use in persons 18 years of age and above.
