Pfizer Inc.’s Paxlovid has become such a part of the COVID-19 treatment scene in the U.S. that it’s easy to forget it’s only authorized for emergency use. That could soon change. The FDA is convening its Antimicrobial Drugs Advisory Committee March 16 to consider Pfizer’s NDA for the co-packaged nirmatrelvir and ritonavir treatment.
Noting that the FDA had rejected its previous proposal last year to voluntarily withdraw Makena from the U.S. market, Covis Pharma BV is again offering to voluntarily withdraw the drug, which is the only drug approved to reduce the risk of preterm birth. Along with its offer, the company asked the agency “to allow for an orderly wind-down that would best serve the interests of the patients,” according to a March 6 letter from Covis’ attorney to FDA Commissioner Robert Califf and Namandjé Bumpus, the agency’s chief scientist.
Although the U.S. FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) voted unanimously, 12-0, March 1 that the data GSK plc presented was adequate to support the safety of its respiratory syncytial virus vaccine, several panelists cautioned the FDA against viewing the vote as a recommendation to license the vaccine before more data are available.
Safety likely will be top of mind when the U.S. FDA’s Vaccines and Related Biologic Products Advisory Committee meets Feb. 28 and March 1 to advise the agency on two respiratory syncytial virus (RSV) vaccines proposed for use in adults who are at least 60 years old.
To increase transparency at its advisory committee (adcom) meetings, the U.S. FDA is proposing asking guest speakers to voluntarily disclose their financial interests and professional relationships to determine their eligibility to give a presentation at an adcom meeting.

Harmonization and simplification won the day as the U.S. FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) looked toward the future of COVID-19 vaccines in the U.S. Jan. 26. The committee voted unanimously, 21-0, to recommend using the same strain composition for all COVID-19 vaccines available in the U.S., whether they’re used for primary doses or boosters. Such standardization also would align the composition of Novavax Inc.’s protein-based vaccine with that of the mRNA vaccines produced by Moderna Inc. and Pfizer Inc.-Biontech SE.
As the SARS-CoV-2 virus that’s responsible for COVID-19 continues to evolve across the world, a global response, similar to what’s used with influenza, would be ideal in evaluating and recommending vaccine strain composition changes from year to year. But “the current diversity of vaccine manufacturers and complexities in global supply of COVID-19 vaccines would make a globally coordinated, simultaneous vaccine composition evaluation and recommendation quite challenging,” the U.S. FDA said in its briefing document for the Jan. 26
meeting of the Vaccine and Related Biological Products Advisory Committee.
Albeit with complaints and provisos, the U.S. FDA’s Antimicrobial Drugs Advisory Committee (ADAC) rubber-stamped Cidara Therapeutics Inc.’s rezafungin, an injectable treatment for candidemia and invasive candidiasis (IC) in adults. Panelists were asked to vote on a single question: “Is the overall benefit-risk assessment favorable for the use of rezafungin for treatment of candidemia/IC in adults with limited or no alternative treatment options?” The balloting turned out 14 yes, one no.
Next week, Cidara Therapeutics Inc. will make its case for rezafungin, an injectable treatment for candidemia and invasive candidiasis in adults, before the U.S. FDA’s Antimicrobial Drugs Advisory Committee. When it convenes Jan. 24, the adcom will vote either yes or no if it believes the overall benefit-risk assessment is favorable for the use of rezafungin for treating candidemia/invasive candidiasis in adults with limited or no alternative treatment options.
