Amid pressure to get a COVID-19 vaccine authorized for infants and toddlers sooner than later, Pfizer Inc. and Biontech SE initiated a rolling submission seeking to amend the U.S. FDA’s emergency use authorization for their mRNA vaccine to include children 6 months through 4 years of age.
Once again, the U.S. FDA giveth and it taketh away. Just a few days after expanding its approval for Gilead Sciences Inc.’s Veklury (remdesivir) to provide access to more people infected with COVID-19, the FDA essentially shut down the use of two monoclonal antibody (mAb) treatments Jan. 24 that had been authorized to treat mild-to-moderate COVID-19 infections – Regeneron Inc.’s Regen-Cov (Ronapreve in Europe), an antibody cocktail of casirivimab and imdevimab, and Eli Lilly and Co.’s bamlanivimab and etesevimab that are administered together.
The U.S. FDA’s emergency use authorization for two oral antivirals to be used to treat individuals at high risk of progressing to severe disease is just one hurdle cleared, as Pfizer Inc.’s Paxlovid and Merck & Co. Inc.-Ridgeback Biotherapeutics Inc.’s molnupiravir still have many more laps to run.
The FDA went from zero to two oral antivirals to treat COVID-19 in the space of two days, granting emergency use authorizations last week to Pfizer Inc.’s Paxlovid and Merck & Co. Inc.-Ridgeback Biotherapeutics Inc.’s molnupiravir. Both five-day regimens are authorized for use, within five days of COVID-19 symptom onset, in individuals at high risk of progressing to severe disease, including hospitalization and death.
One of the biggest concerns at the Nov. 30 meeting of the FDA’s Antimicrobial Drugs Advisory Committee is that, if Merck & Co. Inc.-Ridgeback Biotherapeutics Inc.’s antiviral drug, molnupiravir, is authorized for use in treating mild to moderate COVID-19 in patients at high risk of progressing to severe disease, it might be used too broadly, given its potential risks.
Former FDA Commissioner Stephen Hahn is being asked to spill the beans on political interference at the U.S. agency during the emergence of COVID-19 last year.
The FDA has granted emergency use authorization (EUA) to the COVID-19 vaccine created by Pfizer Inc.-Biontech SE for use in children ages 5 through 11. This is the first EUA for a COVID-19 vaccine to be awarded for this group of roughly 28 million children in the U.S. and it comes after weeks of lengthy debate among experts about the wisdom of targeting the young demographic.
As largely expected, the FDA on Oct. 20 authorized the use of booster doses for COVID-19 vaccines from Moderna Inc. and Johnson & Johnson, in line with last week’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) meetings. It also cleared the way for “mix-and-match” boosters, allowing eligible people to receive boosters from any of the FDA-approved vaccines, regardless of which vaccine they received originally.
Now that Pfizer Inc.-Biontech SE has submitted initial phase II/III study data to the FDA bolstering the case for an emergency use authorization (EUA) for its COVID-19 vaccine to children ages 5 through 11 years, the competition, including Moderna Inc., Novavax Inc. and Sanofi SA, falls further behind.
With the U.S. logging more than 4 million new COVID-19 cases in the past few weeks, federal purchasing of antibody cocktails from Regeneron Pharmaceuticals Inc. and Eli Lilly and Co. is continuing to grow. The government has placed orders for $2.94 billion worth of Regeneron's REGEN-COV (casirivimab and imdevimab) and about $330 million of Lilly's etesevimab to complement doses of bamlanivimab it previously purchased. Both antibody combinations, approved under FDA emergency use authorizations (EUAs), have been shown to reduce risk of hospitalization or death from COVID-19.
