NVX-CoV2373 COVID-19 Vaccine Description
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’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.
A Phase 1 clinical trial of NVX‑CoV2373 initiated in Australia during May 2020. 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.
All subjects in this study developed anti-spike IgG antibodies after a single vaccine dose. Many of them also developed wild-type virus-neutralizing antibody responses. After Dose #2, 100% of participants developed wild-type virus-neutralizing antibody responses. Both anti-spike IgG and viral neutralization responses compared favorably to responses from patients with clinically significant COVID‑19 disease.
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.

NVX-CoV2373 COVID-19 Vaccine History
On September 2, 2020, the New England Journal of Medicine published further detail on the previously announced results. NVX‑CoV2373 demonstrated a reassuring safety and reactogenicity profile and induced robust antibody responses numerically superior to that seen in human convalescent sera.
The Phase 2 portion will assess immunity, safety, and COVID-19 disease reduction in up to 1,500 volunteers in the USA and Australia, with approximately 50 percent between 60 and 84 years of age.
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 (OWS). Novavax uses the OWS funding to complete late-stage clinical development, including a pivotal Phase 3 clinical trial, establishing large-scale manufacturing, and delivering 100 million doses of NVX‑CoV2373 beginning as early as late 2020. 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 'has 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.
And a press statement issued on November 30, 2020, “Novavax is in a leading position to significantly contribute to the need for safe and efficacious vaccines that will ultimately end the worldwide COVID-19 pandemic,” said Stanley C. Erck, CEO, Novavax. “We continue to make meaningful progress as we work to test, manufacture, and ultimately deliver NVX-CoV2373 with unprecedented speed, as well as put partnerships in place that would ensure widespread and equitable access worldwide.”
On December 10, 2020, the NEJM published a review, which found 'At 35 days, NVX-CoV2373 appeared to be safe, and it elicited immune responses that exceeded levels in Covid-19 convalescent serum. The Matrix-M1 adjuvant-induced CD4+ T-cell responses were biased toward a Th1 phenotype.'
On December 28, 2020, NIAID Director Anthony S. Fauci, M.D., said in a press statement, “The launch of this study, the fifth investigational COVID-19 vaccine candidate to be tested in a Phase 3 trial in the USA, demonstrates our resolve to end the pandemic through the development of multiple safe and effective vaccines.”
On January 6, 2021, Karen Kotloff, M.D., stated in a University of Maryland School of Medicine press release, “This virus has not been democratic. We have seen that it has impacted minorities, the elderly, and people with certain medical conditions the hardest. So an important goal of this research is to learn about the safety and effectiveness of the vaccine in these groups."
On January 7, 2021, Novavax stated 'it is currently conducting late-stage clinical studies to demonstrate the efficacy, safety, and immunogenicity of NVX-CoV2373 to prevent COVID-19. This includes two large pivotal Phase 3 clinical trials in the United States/Mexico (the PREVENT-19 trial) and the United Kingdom, as well as a Phase 2b trial in South Africa.'
“The continued increase in significant COVID-19 transmission in virtually all parts of the world underscores the need for multiple safe, efficacious vaccines in enormous quantities to stop the pandemic,” added Stanley C. Erck, Novavax President and Chief Executive Officer. “We appreciate the confidence of the Australian government and the opportunity to play a role in ensuring that its citizens will have access to a protein-based vaccine that can be distributed using existing distribution channels, should it receive regulatory approval.”
On January 28, 2021, the company issued a press statement announcing that NVX-CoV2373, its protein-based COVID-19 vaccine candidate, met the primary endpoint, with a vaccine efficacy of 89.3%, in its Phase 3 clinical trial conducted in the United Kingdom (UK). The study assessed efficacy during a period with high transmission and a new UK variant strain of the virus emerging and circulating widely. It was conducted in partnership with the UK Government’s Vaccines Taskforce. Novavax also announced successful results of its Phase 2b study in South Africa. Novavax expects to share further details of the UK trial results as additional data become available.
"These are spectacular results, and we are very pleased to have helped Novavax with the development of this vaccine. The efficacy shown against the emerging variants is also extremely encouraging. This is an incredible achievement that will ensure we can protect individuals in the UK and the rest of the world from this virus,” added Clive Dix, Chair, UK Vaccine Taskforce.
Statement from Dr. Richard Hatchett, CEO of CEPI, on January 29, 2021, “It is extremely encouraging that the Novavax, NVX-CoV2373, protein-based COVID-19 vaccine candidate has demonstrated 89.3% efficacy in a Phase 3 UK trial and shows good efficacy against the newly identified variant B.1.1.7. South Africa's data showing lower efficacy of this highly effective vaccine against B.1.351 is the first direct data to confirm this variant's ability to evade our vaccines partially. It is good to hear that Novavax has moved so quickly to initiate the development of new constructs against the emerging strains to identify candidates for booster or bivalent vaccines." As of January 29, 2021, the PREVENT-19 study has randomized over 16,000 participants and expects to complete the targeted enrollment of 30,000 patients in the first half of February 2020.
As of February 4, 2021, Novavax had begun the rolling review process with several regulatory agencies worldwide, including the European Medicines Agency, U.S. Food and Drug Administration, U.K. Medicines and Healthcare products Regulatory Agency, and Health Canada. “The rolling review of our submission by regulatory authorities of non-clinical data and early clinical studies will help expedite the review process and bring us that much closer to delivering a safe and effective vaccine worldwide,” said Gregory M. Glenn, M.D., President of Research and Development, Novavax.
Novavax previously announced it was awarded $1.6 billion in funding from the U.S. government to meet its Operation Warp Speed goals to expedite the delivery of millions of doses of safe, effective vaccines for COVID-19. The award is funding the U.S. and Mexico pivotal Phase 3 trial and manufacturing scale-up.
