The emergence of the Omicron variant of the SARS-CoV-2 virus has sparked a vigorous reaction around the globe, which in the U.S. includes steps taken by the Biden administration to ensure that the roughly 100 million people who have received an initial vaccination regime will receive a booster if eligible. The administration also reported Dec. 2 that it will take steps to ensure that home testing will be covered by private payers, all of which amounts to a massive boost in business for manufacturers of vaccines and tests despite concerns about how the Omicron variant might affect vaccine and test performance.

The FDA’s device center is required to develop and publish special controls for devices that are deemed class II items via the de novo petition process, and five such declarations were posted Dec. 1 to the Federal Register. One of these de novo classifications, for conditioning tools for eating disorders, was the subject of a de novo petition filed in 2007 and granted in 2011.

Device makers have historically struggled to maintain adequate procedures for corrective and preventive action (CAPA) and complaint handling (CH), and two warning letters posted to the FDA website suggest these are still sore spots. Invacare Corp., of Elyria, Ohio, and Smiths Medical ASD Inc., of Minneapolis, were both cited for CAPA and CH deficiencies.

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.

Beyondspring Pharmaceuticals Inc. said it received a complete response letter from the FDA regarding the NDA for plinabulin, the company’s lead asset. The FDA said results of a phase III registrational trial were strong enough to show benefit but a second trial is needed to satisfy the agency.

While the FDA’s reaction to the results of the Nov. 30 advisory hearing for the COVID-19 therapy molnupiravir is difficult to predict, demand for rapid antigen tests may jump considerably when this or any such product is approved. That increased demand could crunch supplies of these tests due to the convergence of any such approvals, the upcoming holiday season, and the 2021-22 flu season, a convergence that could hamper efforts to roll out these new therapies.

Following an FDA priority review, Takeda Pharmaceutical Co. Ltd.'s oral antiviral, maribavir, has won U.S. approval as the first drug in the country to treat resistant cytomegalovirus (CMV) infection and disease in adult and pediatric transplant recipients. The drug will be marketed as Livtencity.
