Valneva and IDT Biologika Agree on Termination of their COVID-19 Collaboration

Saint-Herblain (France) and Dessau-Roßlau (Germany), September 16, 2022 – ValnevaSE (Nasdaq: VALN; Euronext Paris: VLA), a specialty vaccine company, and IDT Biologika today announced they have agreed to terminate their collaboration following the delivery of inactivated COVID-19 bulk vaccine to Valneva, and considering the current order levels and existing inventories.

As per the commercial manufacturing services agreement signed in November 20211, IDT Biologika produced VLA2001 bulk vaccine at its Biosafety Level 3 facilities in Germany, and Valneva bought the batches that were manufactured so far by IDT. In light of the reduced European Commission order2, Valneva has suspended manufacturing of the vaccine and, as compensation, will pay IDT up to €36.2 million in cash and the equivalent of €4.5 million in kind, in the form of specified equipment purchased by Valneva.

Valneva has started to deliver doses of VLA2001 to the European Member States who ordered the vaccine and is retaining inventory for potential additional supply to these Member States should demand increase. In parallel, the Company is continuing discussions with various other governments around the world, with the aim to deploy approximately eight to ten million doses of remaining inventory into international markets in the next six to twelve months.

About VLA2001
VLA2001 is produced on Valneva’s established Vero-cell platform, leveraging the manufacturing technology for Valneva’s licensed Japanese encephalitis vaccine, IXIARO®. VLA2001 consists of inactivated whole virus particles of SARS-CoV-2 with high S-protein density, in combination with two adjuvants, alum and CpG 1018. This adjuvant combination has consistently induced higher antibody levels in preclinical experiments than alum-only formulations and shown a shift of the immune response towards Th1. CpG 1018 adjuvant, supplied by Dynavax Technologies Corporation (Nasdaq: DVAX), is a component of the US FDA- and EMA-approved HEPLISAV-B® vaccine. VLA2001’s manufacturing process, which has already been upscaled to final industrial scale, includes chemical inactivation to preserve the native structure of the S-protein. VLA2001 is expected to conform with standard cold chain requirements (2 to 8 degrees Celsius).
VLA2001 is the first COVID-19 vaccine to receive a standard marketing authorization in Europe3 and the only whole virus, inactivated, adjuvanted COVID-19 vaccine to receive marketing authorization in Europe for use as primary vaccination in people from 18 to 50 years of age. The vaccine was also granted conditional marketing authorization in the United Kingdom4 and emergency use authorization in the United Arab Emirates5 and Kingdom of Bahrain6. Valneva currently has agreements to supply VLA2001 to certain EU Member States7 and the Kingdom of Bahrain8. In August 2022, the World Health Organization (WHO) issued recommendations for use of VLA20019.
