Valneva switches focus to bilateral discussions to supply its inactivated, adjuvanted COVID-19 vaccine candidate VLA2001

ValnevaValneva SE, a specialty vaccine company focused on the development and commercialization of prophylactic vaccines for infectious diseases with significant unmet medical need, announced it is now focusing on bilateral discussions, on a country by country basis, to supply its inactivated, adjuvanted COVID-19 vaccine candidate, VLA2001, and is consequently deprioritizing the ongoing centralized discussions with the European Commission (EC).

This follows the recent announcement on April 6, 2021 of positive initial results from the Phase 1/2 clinical trial of VLA2001[1].

Valneva previously announced the advanced stage of its discussions, which started in the third quarter of 2020, with the EC on January 12, 2021[2]. In September 2020, Valneva announced a collaboration with the UK government to provide up to 190 million doses of VLA2001 through 2025[3], of which 100 million doses have already been ordered.

Thomas Lingelbach, Chief Executive Officer of Valneva, said, "We've committed significant time and effort to try to meet the needs of the central EC procurement process. Despite our recent clinical data, we have not made meaningful progress and have not yet secured a supply agreement. We are therefore now focusing our efforts on those European Union member states, and interested parties outside the EU, who would like to include our inactivated approach within their vaccination strategy. We are convinced that VLA2001 has an important role to play in the future, including boosters or potential modifications to the vaccine to address variants."

Valneva has the only inactivated vaccine candidate in clinical trials against COVID-19 in Europe and is preparing a pivotal, comparative immunogenicity Phase 3 clinical trial expected to commence by the end of April 2021 with the aim of making regulatory licensure submissions in the autumn of 2021.

About the Novel Coronavirus SARS-CoV-2 and COVID-19 Disease

SARS-CoV-2 is a new coronavirus identified in late 2019 and belongs to a family of enveloped RNA viruses that include MERS and SARS, both of which caused serious human infections of the respiratory system. The virus, which causes a disease named COVID-19, has never before been found in humans. Since this outbreak was first reported, the virus has caused millions of deaths globally[4]. It has been declared a pandemic by the World Health Organization (WHO).

About VLA2001

VLA2001 is currently the only whole virus, inactivated, adjuvanted vaccine candidate in clinical trials against COVID-19 in Europe. It is intended for active immunization of at-risk populations to prevent carriage and symptomatic infection with COVID-19 during the ongoing pandemic and potentially later for routine vaccination including addressing new variants. VLA2001 may also be suited for boosting, as repeat booster vaccinations have been shown to work well with whole virus inactivated vaccines. 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. The manufacturing process for VLA2001, which has already been upscaled to final industrial scale, includes inactivation with BPL to preserve the native structure of the S-protein. VLA2001 is expected to conform with standard cold chain requirements (2 degrees to 8 degrees Celsius).

About Valneva SE

Valneva is a specialty vaccine company focused on the development and commercialization of prophylactic vaccines for infectious diseases with significant unmet medical need. We take a highly specialized and targeted approach to vaccine development, beginning with the identification of deadly and debilitating infectious diseases that lack a prophylactic vaccine solution and for which there are limited therapeutic treatment options. We then apply our deep understanding of vaccine science, including our expertise across multiple vaccine modalities, as well as our established vaccine development capabilities, to develop prophylactic vaccines to address these diseases. We have leveraged our expertise and capabilities both to successfully commercialize two vaccines and to rapidly advance a broad range of vaccine candidates into and through the clinic, including candidates against Lyme disease, the chikungunya virus and COVID-19.
