Now that Novavax Inc. has received an emergency use authorization (EUA) from the U.S. FDA allowing adults to receive the adjuvanted vaccine to ward off severe acute COVID-19, it’s time for the CDC to weigh in. Once its Advisory Committee on Immunization Practices meets July 19 to discuss the vaccine and make a policy recommendation, the vaccine will be available on the market.
Shares of Novavax Inc. dropped 19% after briefing documents released ahead of the U.S. FDA’s June 7 advisory committee raised concerns about risks of myocarditis associated with COVID-19 vaccine NVX-CoV2373, though reviewers also noted the vaccine could offer protection against the omicron variant. The stock (NASDAQ:NVAX) closed June 3 at $44.76, down $11.21.
South Korea’s Ministry of Food and Drug Safety (MFDS) has greenlighted Novavax Inc.’s Nuvaxovid, making it the first protein-based COVID-19 vaccine to be approved for commercial use in the country. The regulatory win for Novavax adds to emergency use authorizations (EUA) for the product, also known as NVX-CoV2373, in India, Indonesia and the Philippines, as well as an emergency use listing from the World Health Organization. On Jan. 12, the company said it expects to submit an EUA request to the FDA after one month.
Aridis Pharmaceuticals Inc. is one of two companies posting COVID-19 data just days before Christmas. Its fully human monoclonal antibody cocktail, AR-701, was shown to be broadly reactive against COVID-19 variants, including Omicron, in preclinical research. Moderna Inc. also posted new data that showed preliminary neutralizing data against Omicron following 50-mg doses of its vaccine, which is currently authorized, and 100-mg dose boosters, which increased neutralizing antibody levels 83-fold from the pre-boost levels.
Pfizer Inc. scored a $5.29 billion deal with the U.S. government to provide 10 million courses of the company’s oral antiviral candidate Paxlovid (PF-07321332; ritonavir) for COVID-19, as Astrazeneca plc and Novavax Inc. also generated news in the space. Paxlovid, if approved or authorized, would be the first oral antiviral of its kind: a 3CL protease inhibitor specifically designed to combat SARS-CoV-2. New York-based Pfizer is seeking emergency use authorization (EUA) from the FDA. Rolling submissions have also commenced in several other countries, and the company continues to build its case for regulatory agencies around the world.
Plants could be an alternative vaccine platform for both COVID-19 and future pandemics, shaking up a biologics sector that is currently mostly protein-based. South Korean company Bioapplications Inc., for example, is aiming to have a plant-derived booster shot for COVID-19 in the clinic in 2022.
Novavax Inc. now says it plans to submit an emergency use authorization (EUA) to the FDA for its highly efficacious COVID-19 vaccine, NVX-CoV2373, sometime in the fourth quarter, backing off previous plans of a second-quarter and then a third-quarter filing.
Novavax Inc. reported an overall efficacy rate of 90.4% in a phase III trial of its COVID-19 protein subunit vaccine, NVX-CoV2373, which it conducted in the U.S. and Mexico. The vaccine provided 100% protection against moderate and severe disease and 100% protection against variants of SARS-CoV-2 deemed not to be of concern or interest. Gaithersburg, Md.-based Novavax is on track to file for approval during the third quarter. By the end of that period, it aims to ramp up production to a monthly run rate of 100 million doses and it aims to scale that to a monthly run rate of 150 million doses by the end of the fourth quarter.
Novavax Inc. backed off its guidance of submitting an EUA for its COVID-19 vaccine in June, pushing the anticipated date to this fall. “We expect to complete regulatory filings in the third quarter,” Stan Erck, Novavax’s president and CEO, told investors on a May 10 conference call. “We hope to have market authorizations in multiple countries in the third quarter, as early in the quarter as possible.”
Amid what Moderna Inc. called "overwhelming" demand from global governments for mRNA vaccines and boosters with efficacy against SARS-CoV-2 variants of concern, the company said both its authorized vaccine, mRNA-1273, and a strain-matched candidate, mRNA-1273.351, increased neutralizing titers against the variants.
