Valneva COVID-19 Vaccine (VLA2001) Description For 2022

Valneva SE's COVID-19 (VLA2001) vero cell-based, highly purified, whole-virus, inactivated vaccine is targeted against the SARS-CoV-2 beta coronavirus 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. VLA2001 is currently the only whole virus, inactivated, adjuvanted COVID-19 vaccine in clinical development in Europe.

Valneva SE's adjuvant combination has consistently induced higher antibody levels in preclinical experiments than alum-only formulations and has shifted 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 has already been upscaled to the final industrial scale and includes inactivation with BPL to preserve the native structure. CpG 1018 is a component of the US FDA-approved HEPLISAV-B® vaccine.

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

The Cov-Compare (VLA2001-301) study results announced on October 18, 2021, were based on 4,012 participants aged 18 years and older across 26 trial sites in the U.K. The trial met its co-primary endpoints: VLA2001 demonstrated superiority against AZD1222 in terms of geometric mean titer for neutralization antibodies (GMT ratio=1.39, p<0.0001), (AZD1222, ChAdOx1-S) GMT 576.6, as well as non-inferiority in terms of seroconversion rates (SCR above 95% in both treatment groups) at two weeks after the second vaccination (i.e., Day 43) in adults aged 30 years and older. Furthermore, T-cell responses analyzed in a sub-set of participants showed that VLA2001 induced broad antigen-specific IFN-gamma producing T-cells reactive against the S- (74.3%), N- (45.9%), and M- (20.3%) protein. In addition, the tolerability profile of VLA2001 was significantly more favorable compared to the active comparator vaccine.

On April 14, 2022, the U.K.'s Medicines and Healthcare products Regulatory Agency approved the Valneva COVID-19 vaccine after meeting the required safety, quality, and effectiveness standards. It is also the first whole-virus inactivated COVID-19 vaccine to gain regulatory approval in the U.K. On March 1, 2022, the National Health Regulatory Authority of the Kingdom of Bahrain granted authorization for VLA2001.

The Company announced on April 25, 2022, an update on the rolling review process with the Committee for Medicinal Products for Human Use ("CHMP") of the European Medicines Agency (EMA), which accepted the Marketing Authorization Application filing on May 19, 2022. The CHMP concluded on June 23, 2022, that the benefits of COVID-19 Vaccine Valneva outweigh its risks and recommended granting a standard marketing authorization in the EU - EMEA/H/C/006019. The European Commission granted marketing authorization in Europe for Valneva’s inactivated whole-virus COVID-19 vaccine on June 24, 2022.

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. The Company's vision is to contribute to a world where no one dies or suffers from preventable diseases through vaccination. Valneva also works with agencies outside the European Union for potential future approvals and additional purchase agreements.

Valneva COVID-19 Vaccine Omicron BA.x

On January 19, 2022, Valneva announced results from an initial laboratory study demonstrating that serum antibody induced by three doses of VLA2001 neutralizes the Omicron variant. All 30 samples (100%) presented neutralizing antibodies against the ancestral virus and Delta variant, and 26 samples (87%) showed neutralizing antibodies against the Omicron variant. The mean fold reduction of neutralization relative to the ancestral virus was 2.7-fold for Delta and 16.7-fold for Omicron. Previously, on December 16, 2021, the Company confirmed a phase 1/2 study evaluating sera from boosted participants for cross-neutralization against variants, including Omicron.

Valneva COVID-19 Vaccine Cell Line

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.

Valneva 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, that Valneva is continuing its VLA2001 development plan. In addition, testing for the Company's pivotal Phase 3 trial, Cov-Compare, is ongoing at Public Health England ("PHE"). Subject to these data and MHRA approval, Valneva believes that initial approval for VLA2001 could be granted in late 2021.

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 U.K.'s Medicines and Healthcare products Regulatory Agency (MHRA)" The MHRA requires a final assay validation to verify the integrity of the VLA2001-301 data remains ongoing. It is a prerequisite for the final submission of the clinical study report. 

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. 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 addition, 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 2020 to achieve the first regulatory approval in the second half of 2021, subject to the appropriate regulatory authority requirements.

Valneva COVID-19 Vaccine Indication

Valneva SE's VLA2001 is a whole virus, inactivated, and adjuvanted vaccine indicated to prevent SARS-Cov-2 infection, which causes COVID-19 disease. Valneva's inactivated vaccine candidate is expected to have a 2-dose regimen (day 0, 21). There are no data on immunocompromised people (people with weakened immune systems).

Valneva COVID-19 Vaccine For Children

As of June 24, 2022, COVID-19 Vaccine Valneva is not currently authorized in Europe for use in people below 18 years of age. EMA has agreed with the company on a plan to trial the vaccine in children at a later stage.

Valneva COVID-19 Vaccine For Women

Animal studies do not show any harmful effects in pregnancy; however, data on the use of COVID-19 Vaccine Valneva during pregnancy are limited and it is currently not known if the vaccine is present in human milk.

Valneva COVID-19 Booster Effectiveness

The Company announced Phase 1/2 study's initial results on December 16, 2021, confirming that VLA2001 significantly boosted immunity in participants who received VLA2001 as a primary vaccination; 77 of the 153 original participants, aged 18-55 years, received a booster dose of seven to eight months after completion of their primary immunization with either a low, medium or high dose of VLA2001. All participants received a single booster vaccination with VLA2001 at the same (high) dose level used in the pivotal Phase 3 "Cov-Compare" trial. IgG antibody titers (spike protein-based) were measured at the time of the booster and two weeks after the booster dose; 45 of the 77 boosted participants were included in the final analysis. The third dose of VLA2001 elicited an excellent anamnestic response, with similar antibody levels observed whether participants were initially vaccinated with a low, medium, or high dose (GMT 9699.3 (95%CI: 8497.76, 11070.71)). This represents a strong boosting effect, increasing levels of antibodies against the Wuhan virus 42- to 106-fold, depending on the pre-boosting levels of antibodies. Antibody levels measured two weeks after the booster dose was approximately four-fold higher than those observed two weeks after primary immunization.

Valneva COVID-19 Vaccine Side Effects

As of June 24, 2022, The most common side effects of the COVID-19 Vaccine Valneva are mild and get better within a few days after vaccination. These include headache, muscle pain, tenderness and pain at the injection site, tiredness, and nausea (feeling sick) or vomiting. These may affect more than 1 in 10 people. Valneva reported positive Phase 1/2 data for its COVID-19 vaccine candidate in April 2021. In October 2021, the Company reported that VLA2001 was well tolerated, demonstrating a statistically significant better tolerability profile than the active comparator vaccine. In addition, Valneva has a substantial database on the safety of this inactivated virus approach from its J.E. vaccine, which is FDA/EMA/MHRA approved.

Valneva COVID-19 Vaccine Production

Valneva's facility in Solna, France, dedicated to producing the Company's cholera vaccine, has expanded its capacity to provide full fill and finish operations for the VLA2001 vaccine. In addition, VLA2001 is expected to conform to standard cold chain requirements (2 degrees to 8 degrees Celsius). Valneva has commenced manufacturing for the European Commission supply contract and has some inventory ready for labeling and deployment upon regulatory approval. Valneva expects to have the capacity to produce over a hundred million doses of vaccine per annum through a combination of in-house production and CMO capacity.

On November 29, 2021, Valneva SE and IDT Biologika announced their collaboration for the production of VLA2001. IDT Biologika will produce VLA2001's drug substance at its Biosafety Level 3 facilities in Dessau-Roßlau, Germany, and Valneva's manufacturing site in Livingston, Scotland.
