Novavax Inc has submitted its Novavax Vaccine to the US FDA for Emergency Use Authorization (EUA). If authorized, the NVX-CoV2373 protein-based COVID-19 vaccine candidate would be available for adults 18 years of age and older.

The request for EUA is based on the totality of pre-clinical, clinical and manufacturing-related (CMC) data provided to the agency, including results of two large pivotal clinical trials that demonstrated an overall efficacy of approximately 90 percent and a reassuring safety profile.

“We’re extremely proud of the work of our teams and we look forward to FDA’s review of our EUA request. We believe our vaccine offers a differentiated option built on a well-understood protein-based vaccine platform that can be an alternative to the portfolio of available vaccines to help fight the COVID-19 pandemic,” said Stanley C. Erck, President and Chief Executive Officer, Novavax. “I’d like to also extend our thanks for the support of the US Department of Health and Human Services and the US Department of Defense for their partnership leading up to today’s milestone of EUA request submission.”

Novavax conducted two pivotal Phase 3 clinical trials of its Novavax Vaccine: PREVENT-19 which enrolled approximately 30,000 participants in the U.S. and Mexico and published results in the New England Journal of Medicine (NEJM) and a trial with almost 15,000 participants in the U.K. which was also published in NEJM. In both trials, the vaccine demonstrated efficacy with a reassuring safety profile. Serious and severe adverse events were low in number and balanced between vaccine and placebo groups. The most common adverse reactions observed during clinical studies (frequency category of very common ≥1/10) were headache, nausea or vomiting, myalgia, arthralgia, injection site tenderness/pain, fatigue, and malaise. 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 in authorized markets. As part of the PREVENT-19 trial, a booster study is ongoing to evaluate the safety and effectiveness of a third does of the vaccine, as well as a study in adolescents aged 12-17.

The Novavax Vaccine (NVX-CoV2373) has been granted conditional authorization by multiple regulatory agencies worldwide, including the European Commission, and emergency use listing (EUL) from the World Health Organization (WHO), with additional filings currently under review.

The Novavax Vaccine (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.
