The federal government ordered about 450,000 doses of sotrovimab, at a cost of about $2,100 a person. Studies published in December found that even when bathed in monoclonal antibodies on a Petri dish, Omicron particles could keep reproducing. Federal data shows Florida got nearly 4,000 doses of sotrovimab as recently as January 17. Federal health officials plan to assess at the end of this week whether to pause shipments of the Eli Lilly and Regeneron products to individual states, based on how dominant Omicron becomes in different regions of the country, according to a senior administration official who spoke on condition of anonymity. The FDAs decision, based on lab studies of the treatments, mirrors the practices of many healthcare providers, who had been administering the two drugs to treat lingering Delta infections, but stopped as Omicron cases dominated. Omicron overpowers key COVID antibody treatments in early tests Nearly all of the monoclonal antibodies used to prevent severe disease fail to stand up to the Sotrovimab, a treatment from Vir Biotechnology and GlaxoSmithKline, is expected to remain effective against omicron Some monoclonal antibody treatments are effective and free to high-risk coronavirus patients, but experts say the treatment alone cannot prevent the next surge.

Begin treatment within 10 days of the start of symptoms. Then an older drug, remdesivir, emerged as an effective option. Over the next few months, the supply crunch on other highly effective COVID-19 treatments that can be taken at home as pills or given in a single infusion is expected to ease. The broadly neutralizing antibodies we described were more efficient in vitro than many antiSARS-CoV-2 monoclonals previously approved by the FDA for treatment or prevention, said Hugo Mouquet, the head of the Laboratory of Humoral Immunology at the Institut Pasteur and a lead investigator of the study. Scientists found that both Regeneron and Lillys antibodies did a poor job of blocking the variant virus from invading cells. Meanwhile, hospitals are deciding whether or not to keep giving the Eli Lilly and Regeneron treatments to patients, because theyre not effective against Omicron.

Now, with Omicron responsible for more than 99 percent of cases nationally, the FDA argues that it doesnt make sense to use the two ineffective monoclonal antibody treatments anywhere. Vaccines still prevent severe disease from the Omicron variant because they prompt the body to develop antibodiesand more complicated systems, like white blood cellsfor a whole range of bricks.
