Commercialized vaccines

JAPANESE ENCEPHALITIS VACCINE (IXIARO ^(R)/JESPECT ^(R))

Strong sales growth driven by US military supply

In the first quarter of 2017, IXIARO ^(R)/JESPECT ^(R) revenues increased to ?,?15.6 million compared to ?,?14.6 million in the first quarter of 2016, mainly driven by strong sales to the US military. This sales increase follows an update in the US Navy medical guidance at the end of 2016, stating that Japanese Encephalitis vaccination is now required for all Navy personnel and DoD employees assigned to Japan or the Korean peninsula for over 30 days. At the time of this update, vaccination against Japanese encephalitis was already required for U.S Air Force personnel and the Marine Corps so assigned. Based on first quarter revenues, Valneva confirms it expects IXIARO ^(R)/JESPECT ^(R) revenues to reach between ?,?58 and ?,?62 million in 2017, through continued marketing and sales activities and an increase in product adoption by travelers.

CHOLERA / ETEC- DIARRHEA VACCINE (DUKORAL ^(R)[2])

Strong sales performance in Canada, the UK and the Nordics

DUKORAL ^(R) revenues grew to ?,?9.8 million in the first quarter of 2017 compared to ?,?5.4 million in the first quarter of 2016, primarily due to increased sales in Canada (which accounts for more than 50% of global revenue for this product), the United Kingdom and the Nordics. Valneva will continue to invest in growing the DUKORAL ^(R) vaccine through promotional activities and geographic expansion and expects DUKORAL ^(R) sales to grow by approximately 10% in 2017 to ?,?27 million.

Technologies and services

EB66 ^(R) CELL LINE

In the first quarter of 2017, Valneva signed 5 new EB66 ^(R) agreements including a research license with MSD Animal Health for the development of new EB66 ^(R)-based veterinary vaccines and a commercial license with Bavarian Nordic.

Under the terms of the commercial agreement signed with Bavarian Nordic, the Danish biotech company has the rights to develop and commercialize multiple poxvirus-based vaccines on the EB66 ^(R) cell-line. The deal also includes the possibility for Bavarian Nordic to transfer, upon regulatory approvals, some of its existing product candidates produced on chicken embryonic fibroblast (CEF) onto Valneva's EB66 ^(R) technology.

Valneva expects to sign additional agreements for the licensing of its EB66 ^(R) vaccine platform in the coming quarters.

Vaccine Candidates

CLOSTRIDIUM DIFFICILE VACCINE CANDIDATE- VLA 84

Partnering agreement sought in 2017

Clostridium difficile (C. difficile) is the most common infectious cause for nosocomial diarrhea in Europe and the US. There are an estimated 450,000 cases of C. difficile in the US annually^[3] and no vaccine against the disease is commercially available.

Valneva seeks to partner its Clostridium difficile vaccine candidate and has ongoing discussions with interested parties. Published Phase II data^[4]from the most advanced vaccine program targeting primary prevention of Clostridium Difficile Infections (CDI) indicates that Valneva's VLA84 provides an immunological profile comparable to that other product.

LYME BORRELIOSIS VACCINE CANDIDATE - VLA 15

Patient recruitment progressing in the US & EU

Following clearance from the Food & Drug Administration (FDA) and the Belgian authorities at the end of 2016, Valneva has initiated Phase I clinical trials in the US and Europe, and vaccinated the first subject at the end of January 2017.

Patient recruitment for the Phase I trials is advancing in accordance with the study protocol and the Company intends to accelerate the program's progression with a view to starting Phase II in early 2018.

Currently, there is no licensed vaccine available to protect humans against Lyme disease, a multi systemic tick-transmitted infection affecting more than 300,000 Americans each year. The global market for a vaccine against Lyme disease is estimated at approximately ?,?700 - ?,?800 million annually^[5].

CHIKUNGUNYA VACCINE CANDIDATE - VLA 1553

Expected to enter Phase I in the second half of 2017

Valneva is also working actively on the development of a Chikungunya vaccine and expects to enter Phase I clinical development in the second part of 2017. Pre-clinical data has shown that Valneva's live attenuated vaccine candidate has a good safety profile and the potential to provide long term protection against Chikungunya after a single immunization. The Chikungunya virus (CHIKV) re-emerged from East Africa in 2014, causing devastating epidemics of debilitating and often chronic arthralgia, and is now considered as a major health threat with 180,000 reported cases in the Americas in 2016^[6]. There is currently no antiviral treatment for CHIKV infection and no licensed vaccine to prevent the disease. The global market for a Chikungunya vaccine is estimated at approximately ?,?500 million annually^[7].
