Novavax COVID-19 Vaccine (NVX-CoV2373) Description
Novavax COVID-19 vaccine (NVX-CoV2373) (Covovax) is a prefusion protein coronavirus vaccine candidate 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 NVX-CoV2373 vaccine candidate creates an engineered baculovirus containing a gene for a modified SARS-CoV-2 spike protein. The baculovirus then infects a culture of Sf9 moth cells, which create the spike protein and display it on their cell membranes. The spike proteins are then 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 pre-clinical 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 5 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 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.
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. "We are very encouraged by the data showing that NVX-CoV2373 not only provided complete protection against the most severe forms of the disease but also dramatically reduced mild and moderate disease across both trials. Importantly, both studies confirmed efficacy against the variant strains," said Stanley C. Erck, President, and Chief Executive Officer, Novavax, in a press statement issued on March 11, 2021.
On June 9, 2021, a non-peer-reviewed study, 'Immunogenicity and In vivo protection of a variant nanoparticle vaccine that confers broad protection against emerging SARS-CoV-2 variants' found data showing that a recombinant prefusion-stabilized Spike (rS) protein based on the B.1.351 sequence (rS-B.1.351) was highly immunogenic in mice and produced neutralizing antibodies against SARS-CoV-2/WA1, B.1.1.7, and B.1.351. Mice vaccinated with our prototype vaccine NVX-CoV2373 (rS-WU1) or rS-B.1.351 alone, in combination, or as a heterologous prime-boost, were protected when challenged with live SARS-CoV-2/B.1.1.7 or SARS-CoV-2/B.1.351. Virus titer was reduced to undetectable levels in the lungs post-challenge in all vaccinated mice, and Th1-skewed cellular responses were observed. In addition, a strong anamnestic response was demonstrated in baboons boosted with rS-B.1.351 approximately one year after immunization with NVX-CoV2373 (rS-WU1). An rS-B.1.351 vaccine alone or in combination with prototype rS-WU1 induced protective antibody- and cell-mediated responses that were protective against challenge with SARS-CoV-2 variant viruses.

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, now being 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. Among placebo recipients, at 90 days of follow-up, the illness rate was 8.0% in baseline seronegative participants and 5.9% in baseline seropositive participants.
