The one monoclonal antibody treatment that has performed well against Omicron in laboratory experiments is also the most recently authorized: sotrovimab, "I think 'stopgap' is probably a good description," says Michael Ganio of the American Society of Health System Pharmacists. Omicron has swapped out many of those bricks as it has mutated, and old antibodies might not have anywhere to bind. Dr. Griffin, who sees patients in New York City, said he expects difficult conversations now that major health systems have halted their use until the more effective treatment arrives. The FDA is advising against use of monoclonal antibodies from Eli Lilly and Regeneron to treat the Omicron COVID-19 variant because they are not very effective against this strain of the virus.
