VLA2001 COVID-19 Vaccine Description

Valneva SE's VLA2001 (VLA2101) is a Vero-cell-based, highly purified, inactivated vaccine candidate against the novel beta coronavirus SARS-CoV-2 that causes COVID-19 in humans. VLA2001 consists of inactivated whole virus particles of SARS-CoV-2 with high S-protein density, combined with two adjuvants, alum and CpG 1018.

Valneva SE's adjuvant combination has consistently induced higher antibody levels in preclinical experiments than alum-only formulations and has shown a shift of the cellular immune response towards Th1. VLA2001 is produced on Valneva's established Vero-cell platform, leveraging the manufacturing technology for Valneva's licensed Japanese Encephalitis Vaccine, IXIARO®. The process, which has already been upscaled to the final industrial scale, includes inactivation with BPL to preserve the native structure. CpG 1018 is a component of the US FDA-approved HEPLISAV-B® vaccine.

Valneva has designed a process that primarily uses this platform regarding upstream- and downstream process steps as plug-and-play with moderate adjustments. The process includes inactivation with BPL to preserve the native structure of the S protein. The combination with CpG 1018 is expected to induce a strong immune response and generate high titers of neutralizing antibodies. Thus, an inactivated SARS-CoV-2 vaccine would be suitable for wide deployment, including particularly vulnerable populations. 

VLA2001 is expected to conform with standard cold chain requirements (2 degrees to 8 degrees centigrade).

After positive Phase 1/2 results, VLA2001 progresses into a Phase 3 trial study on April 21, 2021. The Cov-Compare (VLA2001-301) study is a randomized, observer-blind, controlled, comparative immunogenicity trial in approximately 4,000 Adults. And, the new VLA2001-304 phase 3 study will be conducted in New Zealand and recruit approximately 150 participants aged 56 years and older (Cohort 1) to generate additional safety and immunogenicity data in this age group following vaccination with VLA2001 (two doses 28 days apart).

Juan Carlos Jaramillo M.D., Chief Medical Officer of Valneva, commented in a press release issued on August 11, 2021, "We have also been working on Variants of Concern as part of our continued efforts to stay ahead of the virus causing COVID-19, especially since we believe that our inactivated, whole-virus platform will be adaptable across variants. Hence we are extremely pleased to be able to invest in this very important additional clinical trial".

On August 23, 2021, Dr. Jaramillo said in a press release, "We are pleased to begin the regulatory review process for our COVID-19 vaccine with the MHRA. Valneva believes that everyone should have access to technology best suited to protect them against this virus. We are working hard to make our vaccine candidate available as soon as possible."

Saint-Herblain, France-based Valneva SE (Nasdaq: VALN; Euronext Paris: VLA) is a vaccine company specializing in preventing diseases in generating significant or unmet medical needs. Their vision is to contribute to a world where no one dies or suffers from preventable diseases through vaccination.

VLA2001 COVID-19 Vaccine uses the following cell lines: Design and Development of VLA2001: Vero Monkey cells; Production: Vero Monkey cells; Confirmatory Lab Tests: not disclosed.

VLA2001 COVID-19 Vaccine History 

Valneva SE's VLA2001 is currently the only whole virus inactivated adjuvanted vaccine candidate in clinical trials against COVID-19 in Europe.

The Company confirmed on September 13, 2021, Valneva is continuing its VLA2001 development plan. Testing for the Company's pivotal Phase 3 trial, Cov-Compare, is ongoing at Public Health England ("PHE"). In addition, Valneva recently announced that its Phase 3 results are expected to be available early in the fourth quarter and that these results will form part of its rolling submission for conditional approval of VLA2001 with the UK's Medicines and Healthcare products Regulatory Agency ("MHRA"). Subject to these data and MHRA approval, Valneva believes that initial approval for VLA2001 could be granted in late 2021.

The Company announced on April 22, 2020, and collaborates with Dynavax Technologies Corporation to evaluate the adjuvant CpG 1018, a U.S. FDA-approved HEPLISAV-B vaccine component. The combination with CpG 1018 adjuvant is expected to induce a strong immune response and has the potential to generate high titers of neutralizing antibodies.

On September 14, 2020, Valneva announced that Dynavax would supply CpG 1018 to produce up to 100 million vaccine doses in 2021. And, Valneva has the option to purchase up to an additional 90 million doses through 2025.

In July 2020, Valneva agreed in principle with the UK government to provide up to 100 million doses of its SARS-CoV-2 vaccine manufactured in Livingston, Scotland. And a further 30 million to 90 million doses, in aggregate, across 2023 to 2025.

The VLA2001 vaccine candidate is expected to enter clinical studies by the end of 2020 and to reach regulatory approval in the second half of 2021 potentially, said the company.

The VLA2001-201 study announced on December 16, 2020, is a randomized, double-blind trial evaluating the safety and immunogenicity for three dose levels in approximately 150 healthy adults in the UK. Adam Finn, the Chief investigator for the VLA 2001-201 program, Professor of Paediatrics at the University of Bristol, and Consultant at the Bristol Royal Hospital for Children, said, "I'm very pleased and proud to be leading the clinical trials effort to bring this vaccine forward in the UK working alongside a solid team across several National Institute for Health Research NHS sites. We expect this inactivated vaccine containing two adjuvants could generate a broader immune response," added Finn.

The study will be conducted in study sites across the United Kingdom and is supported by the National Institute for Health Research (NIHR). Last Update Posted: December 30, 2020. Estimated Primary Completion Date: February 15, 2021. The primary endpoint read-out will be two weeks after completing the two-dose primary immunization (day 0, 21). Subject to analyzing this data, including selecting the optimal dose currently expected in the early second quarter of 2021, additional trials are expected to commence immediately thereafter.

On January 28, 2021, the Company announced it had commenced production of its inactivated, adjuvanted COVID-19 vaccine candidate parallel to the ongoing clinical studies. In a press release, Thomas Lingelbach, CEO of Valneva, stated, "We are extremely pleased to have achieved these two important milestones in such a short period of time. Our team in Scotland has done an amazing job of getting manufacturing started so quickly. In addition, I want to thank the UK Vaccines Taskforce and the National Institute for Health Research, who have played vital roles in the rapid recruitment and enrollment of the volunteers for the clinical study."

The Interim Chair of the UK government's Vaccines Taskforce Clive Dix said on February 1, 2021, "Valneva's manufacturing site in Scotland is already up and running, ready to supply their promising vaccine as soon as it has proven to be safe and effective and is approved. To best ensure we have enough successful candidates to ensure maximum coverage of the UK population, the Vaccines Taskforce has invested in seven of the most promising vaccines. The further 40 million doses secured through today's deal significantly bolsters our portfolio and gives us future flexibility should we need to revaccinate any of the UK population. I want to thank everyone involved in the development of this vaccine for the hard work that has helped us reach this point and also to pay tribute to those UK citizens who have volunteered to take part in the important clinical trials of this vaccine."

On April 6, 2021, the UK's Health and Social Care Secretary, Matt Hancock, commented, "This vaccine will be made onshore in Livingston in Scotland, giving another boost to British life science, and if approved, will play an important role in protecting our communities. I look forward to seeing the results of the upcoming phase 3 trial."

Valneva announced it had enhanced its Biosafety Level 3 laboratory capabilities in Nantes, Vienna, and Livingston, NJ. Assuming that preclinical activities are successful and the requisite financing is in place, Valneva plans to commence clinical studies by the end of 2020 to achieve the first regulatory approval in the second half of 2021, subject to the appropriate regulatory authority requirements.
