Novavax COVID-19 Vaccine (Nuvaxovid, Covovax, NVX-CoV2373) Description

Novavax COVID-19 vaccine (NuvaxovidCovovax, NVX-CoV2373) is a protein-based vaccine candidate engineered from the genetic sequence of the first strain of the SARS-CoV-2 coronavirus. The vaccine was made using Novavax's proprietary nanoparticle technology, Matrix-M, an adjuvant to enhance immune responses and stimulate high levels of neutralizing antibodies.

Novavax Inc.'s COVID-19 vaccine creates an engineered baculovirus containing a modified coronavirus spike protein gene. The baculovirus then infects a culture of Sf9 moth cells, which generate the spike protein and display it on their cell membranes. Next, the spike proteins are harvested and assembled onto a synthetic lipid nanoparticle about 50 nanometers across, each displaying up to 14 spike proteins.

Novavax's patented saponin-based Matrix-M adjuvant has demonstrated a potent and well-tolerated effect by stimulating the entry of antigen-presenting cells into the injection site and enhancing antigen presentation in local lymph nodes, boosting immune response and helping an immunized person make antibodies against the virus.

Novavax identified the recombinant nanoparticle NVX‑CoV2373 vaccine as its lead COVID-19 candidate following preclinical testing that demonstrated high immunogenicity and high levels of neutralizing antibodies.

The IgG antibody response was significantly correlated with neutralization titers, demonstrating that a significant proportion of antibodies were functional. This study was published on August 6, 2020. And, the adjuvant was dose-sparing, with the lower five µg dose of NVX‑CoV2373 performing comparably with the 25 µg dose. Cellular immune responses were measured in a subset of participants, and NVX‑CoV2373 induced antigen-specific polyfunctional CD4+ T cell responses with a strong bias toward the Th1 phenotype (IFN-g, IL-2, and TNF-a).

On January 28, 2021, NVX‑CoV2373 became the first protein-based vaccine candidate to demonstrate clinical efficacy against the original strain of COVID-19 and both of the rapidly emerging variants in the United Kingdom and South Africa. In addition, the Company announced the final efficacy of 96.4% against mild, moderate, and severe disease caused by the original COVID-19 strain in a pivotal Phase 3 trial in the United Kingdom. 

On June 20, 2021, the NEJM published an ORIGINAL ARTICLE: Safety and Efficacy of NVX-CoV2373 Covid-19 Vaccine. Conclusion - A two-dose regimen of the NVX-CoV2373 protein-based vaccine administered to adult participants conferred 89.7% protection against SARS-CoV-2 infection and showed high efficacy against the B.1.1.7 variant.' Followed by another NEJM Original Article published on June 30, 2021, which concluded: A two-dose regimen of the NVX-CoV2373 vaccine administered to adult participants conferred 89.7% protection against SARS-CoV-2 infection and showed high efficacy against the B.1.1.7 variant.

Novavax COVID-19 Vaccine (Nuvaxovid, Covovax, NVX-CoV2373) History

 On August 4, 2020, Novavax announced the Phase 1 data from its Phase 1/2 clinical trial found the recombinant COVID-19 vaccine candidate adjuvanted with Matrix-M was generally well-tolerated elicited robust antibody responses numerically superior to that seen in human convalescent sera.

A Phase 3, Randomized, Stratified, Observer-Blind, Placebo-Controlled Study to Evaluate the Efficacy, Safety, and Immunogenicity of mRNA-1273 SARS-CoV-2 Vaccine in Adults Aged 18 Years and Older was last updated on October 28, 2020.

The federal government awarded Novavax $1.6 billion as part of Operation Warp Speed. The Coalition for Epidemic Preparedness Innovations is also investing up to $388 million, and the Department of Defense is investing up to $60 million of funding to advance the clinical development of NVX‑CoV2373. As of September 24, 2020, Novavax stated it ''continued to scale-up its manufacturing capacity, currently at up to 2 billion annualized doses, once all capacity has been brought online by mid-2021.''On November 4, 2020, Novavax confirmed various supply agreements with the USA, the United Kingdom, Canada, Australia and partnerships with Japan, South Korea, and India.

On August 30, 2021, the U.S. CDC provided updated guidance for those vaccinated as part of a clinical trial in the U.S. The new guidance states that participants in the Novavax PREVENT-19 Phase 3 clinical trial meets the criteria to be considered fully vaccinated two weeks after they have completed the vaccine series.

Separately, an ORIGINAL ARTICLE - Safety and Efficacy of NVX-CoV2373 Covid-19 Vaccine, was published by the NEJM. CONCLUSIONS: A two-dose regimen of the NVX-CoV2373 vaccine administered to adult participants conferred 89.7% protection against SARS-CoV-2 infection and showed high efficacy against the B.1.1.7 variant. These research findings are summarized in a short video.

Novavax COVID-19 Vaccine (Nuvaxovid, Covovax, NVX-CoV2373) Variant Protection

Novavax, Inc. announced preliminary data on August 5, 2021, demonstrating that functional ACE-2 binding inhibition antibodies cross-reactive with the Delta (B.1.617.2) variant were more than 6-fold higher than the primary vaccination series. And the analysis of sera from primary vaccination series also showed cross-reactive functional antibodies to Alpha, Beta, and Delta variants, all of which increased 6- to 10-fold with boost. The results come from an ongoing Phase 2 study in the U.S. and Australia. Select participants in the 5-microgram dose cohort received a 5-microgram booster dose 189 days after the initial two-dose regimen to examine the functional immune system response.

On November 2, 2021, the Company confirmed it is evaluating its vaccine against the Omicron virus variant. And, Novavax has initiated the development of an Omicron-specific vaccine construct. 

COVID-NanoFlu™ Combination Vaccine

The Company's COVID-NanoFlu™ combination vaccine candidate combines NanoFlu™ and NVX-CoV2373. Both previously demonstrated strong results as standalone vaccines in Phase 3 clinical trials. In preclinical studies, the COVID-NanoFlu Combination Vaccine demonstrated robust immune responses to each component of the quadrivalent influenza vaccine and the SARS-CoV-2 spike protein, with Matrix-M adjuvant playing a key role. A non-peer-reviewed study was published in May 2021.

Novavax and Seqirus Vaccine Co-Administration

On June 14, 2021, the Company announced a non-peer-reviewed manuscript, ''safety, Immunogenicity, and Efficacy of a COVID-19 Vaccine (NVX-CoV2373) Co-administered With Seasonal Influenza Vaccines,'' available at medRxiv.org. As part of Novavax's Phase 3 clinical trial of NVX-CoV2373 in the United Kingdom, 431 volunteers were also enrolled in a co-administration sub-study. All received an approved seasonal influenza vaccine (aTIV, QIVc), with approximately half the participants co-vaccinated with NVX-CoV2373. The study demonstrated that vaccine efficacy appeared to be preserved in those receiving both vaccines compared to those vaccinated with NVX-CoV2373 alone.

The Lancet published a commentary on November 17, 2021, that summarized by saying 'the Novavax COVID-19 vaccine development programs and successes have turbo-charged the whole of vaccinology, conferring the confidence to try new protocols and protect against diverse pathogens, even if this means administering the different vaccines at the same time.' This statement reinforces the U.S. CDC’s interim clinical considerations that COVID-19 vaccines and other vaccines, including influenza vaccines, can be administered without regard to timing.

May 5, 2021 - Novavax, Inc. announced results from the initial primary analysis of a Phase 2b clinical trial conducted in South Africa of its NVX-CoV2373 COVID-19 vaccine candidate in the New England Journal of Medicine (NEJM). The Phase 2b randomized, observer-blinded, placebo-controlled trial conducted in South Africa evaluated the efficacy, safety, and immunogenicity in healthy adults and a small cohort of medically stable adults living with human immunodeficiency virus (HIV). The study met its primary endpoint. NVX-CoV2373 demonstrated an overall efficacy of 49% in the initial analysis (published NEJM) and 49% in the subsequent complete analysis (unpublished). Among healthy adults without HIV, NVX-CoV2373 demonstrated the efficacy of 60% in the initial analysis and 55% in the subsequent complete analysis. In the initial analysis, cases were predominantly mild-to-moderate and due to the B.1.351 variant. However, in the subsequent complete analysis, circulation of the B.1.351 variant continued to dominate, and all five cases of severe disease observed in the trial occurred in the placebo group. The initial analysis, published in NEJM, suggested that prior infection with the original COVID-19 strain did not protect against subsequent infection by the variant predominantly circulating in South Africa through 60 days of follow-up. However, with additional follow-up, the complete analysis of the South Africa trial indicates that there may be a modest protective effect of prior exposure with the original COVID-19 strain. At 90 days of follow-up, the illness rate was 8.0% among placebo recipients in baseline seronegative participants and 5.9% in baseline seropositive participants.
