Yet another potentially high quality COVID-19 vaccine has been authorized on an emergency use basis by the World Health Organization (WHO). Biotech company Novavax (NASDAQ: NVAX) and Indian partner Serum institute of India (SII) the world’s largest vaccine producer by volume announced that WHO granted the partnership Emergency Use Listing (EUL) for NVX-CoV2373, the Novavax recombinant nanoparticle protein-based COVID-19 vaccine with Matrix M adjuvant, for active immunization of individuals 18 years and older for the prevention of SARS-CoV-2, the virus behind COVID-19.

The EUL is applied to the vaccine produced and marketed by SII as COVOVAX™, a novel recombinant, adjuvanted SARS-CoV-2 rS vaccine in India and licensed territories.  Additional EUL filing is now under review by the WHO for vaccine to be marketed by Novavax under the brand name Nuvaxovid ™.

With this additional vaccine now approved Novavax CEO Stanley C. Erck articulated that this authorization should “help overcome barriers to vaccine access in many regions of the world by leveraging the traditional refrigeration used in existing vaccine supply channels, while also offering and option based on a familiar and well-understood technology.”

While Adar Poonawalla, one of the billionaire owners and CEO of  SII, went on the record that “COVOVAX is the first protein-based COVID-19 vaccine option, with demonstrated efficacy and a well-tolerated safety profile, to be made available through the COVAX Facility…”Subscribe to the Trialsitenews “Vaccine” ChannelNo spam – we promise

What’s the EUL grant based on?

The grant of EUL was based on the totality of preclinical, manufacturing, and clinical trial data submitted for review. This includes two pivotal Phase 3 clinical trials: PREVENT-19, which enrolled approximately 30,000 participants in the U.S. and Mexico, the results of which were published December 15, 2021 in the New England Journal of Medicine (NEJM); and a trial that evaluated the vaccine in more than 14,000 participants in the U.K., the results of which were published June 30, 2021 in NEJM. In both trials, NVX-CoV2373 demonstrated high efficacy and a reassuring safety and tolerability profile. Novavax will continue to collect and analyze real-world data, including the monitoring of safety and the evaluation of variants, as the vaccine is distributed.

Other Nations Already Authorized

Novavax and SII recently received emergency use authorization (EUA) for COVOVAX in Indonesia and the Philippines. The vaccine is also currently under review by multiple regulatory agencies worldwide. The company expects to submit its complete chemistry, manufacturing, and controls (CMC) data package to the U.S. FDA by the end of the year.

Emergency Use Listing of COVOVAX by the World Health Organization

The World Health Organization (WHO) has issued Emergency Use Listing for COVOVAX/Recombinant Spike Protein of SARS-CoV-2 Virus 5 mcg for active immunization of individual 18 years of age and older for the prevention of coronavirus disease 2019 caused by SARS-CoV-2.

About NVX-CoV2373 

NVX-CoV2373 is a protein-based vaccine engineered from the genetic sequence of the first strain of SARS-CoV-2, the virus that causes COVID-19 disease. NVX-CoV2373 was created using Novavax’ recombinant nanoparticle technology to generate antigen derived from the coronavirus spike (S) protein and is formulated with Novavax’ patented saponin-based Matrix-M™ adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies. NVX-CoV2373 contains purified protein antigen and can neither replicate, nor can it cause COVID-19.

Novavax’ COVID-19 vaccine is packaged as a ready-to-use liquid formulation in a vial containing ten doses. The vaccination regimen calls for two 0.5 ml doses (5 mcg antigen and 50 mcg Matrix-M adjuvant) given intramuscularly 21 days apart. The vaccine is stored at 2°- 8° Celsius, enabling the use of existing vaccine supply and cold chain channels.

Novavax has established partnerships for the manufacture, commercialization, and distribution of NVX-CoV2373 worldwide.

About the NVX-CoV2373 Phase 3 trials

NVX-CoV2373 is being evaluated in two pivotal Phase 3 trials.

A trial conducted in the U.K. with 14,039 participants was designed as a randomized, placebo-controlled, observer-blinded study and achieved overall efficacy of 89.7%. The primary endpoint was based on the first occurrence of PCR-confirmed symptomatic (mild, moderate, or severe) COVID-19 with onset at least 7 days after the second study vaccination in serologically negative (to SARS-CoV-2) adult participants at baseline.

PREVENT-19, a trial in the U.S. and Mexico, with 25,452 participants, achieved 90.4% efficacy overall. It was designed as a is a 2:1 randomized, placebo-controlled, observer-blinded study to evaluate the efficacy, safety, and immunogenicity of NVX-CoV2373. The primary endpoint for PREVENT-19 was the first occurrence of PCR-confirmed symptomatic (mild, moderate, or severe) COVID-19 with onset at least 7 days after the second dose in serologically negative (to SARS-CoV-2) adult participants at baseline. The statistical success criterion included a lower bound of 95% CI >30%. The key secondary endpoint is the prevention of PCR-confirmed, symptomatic moderate or severe COVID-19. Both endpoints were assessed at least seven days after the second study vaccination in volunteers who had not been previously infected with SARS-CoV-2. It was generally well-tolerated and elicited a robust antibody response in both studies.

About Matrix-M™ Adjuvant

Novavax’ 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.

About Novavax

Novavax, Inc. (Nasdaq: NVAX) is a biotechnology company that promotes improved health globally through the discovery, development, and commercialization of innovative vaccines to prevent serious infectious diseases. The company’s proprietary recombinant technology platform harnesses the power and speed of genetic engineering to efficiently produce highly immunogenic nanoparticles designed to address urgent global health needs. NVX-CoV2373, the company’s COVID-19 vaccine, received Emergency Use Authorization in Indonesia and the Philippines and has been submitted for regulatory authorization in multiple markets globally. NanoFlu™, the company’s quadrivalent influenza nanoparticle vaccine, met all primary objectives in its pivotal Phase 3 clinical trial in older adults. Novavax is currently evaluating a COVID-NanoFlu combination vaccine in a Phase 1/2 clinical trial, which combines the company’s NVX-CoV2373 and NanoFlu vaccine candidates. These vaccine candidates incorporate Novavax’ proprietary saponin-based Matrix-M™ adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies.
