Fortunately, doctors could still give out Regenerons treatment, which remained effective against the variants and was in abundant supply. But treating patients with remdesivir takes three such infusion sessions over consecutive days. The Eli Lilly and Regeneron monoclonal antibody treatments are directed against the spike protein of SARS-CoV-2, and Omicron has 32 mutations and a deletion The FDA said the drug should be administered only when other treatment options arent accessible or clinically appropriate.

Sotrovimab just happens to target spots of the virus that went unchanged. The FDA left the door open for the return of the treatments if the prove effective against future variants. The emergence of an Omicron sub-variant, BA.2, has made it even harder to get the right monoclonal antibodies to the right patients. The antiviral treatmentremdesivir, which was previously only used during hospitalization, can now be used in mildly ill patients, but the drug requires three lengthy infusions. We did that because we felt there was utility early on in being able to say on the same day, this person likely has Delta, and so they can have Regeneron, and this person likely has Omicron, and they could get sotrovimab, says S. Wesley Long, the clinical director of diagnostic microbiology at Houston Methodist Hospital. One bright spot is that the U.S. Food and Drug Administration on Wednesday gave emergency authorization for an antiviral produced by Pfizer called Paxlovid the first oral monoclonal antibody. Genomic sequencing, which public health researchers use to track COVID variants, takes at least a few days, but often stretches into a weekby which time, the window for antibody treatment has passed. While its critical that we have ways to treat those who contract COVID-19, the authorized treatments are not a substitute for vaccination in individuals for whom COVID-19 vaccination and a booster dose are recommended.

Long-term protection against severe COVID-19 is generated by memory B-cell and antibody responses to the viruss spike protein. Should the BA.2 subvariant grow in proportion in the U.S., this potential treatment may help ensure that we can continue to offer monoclonal antibody treatment that works against that strain of the virus..

Dr. Lindsay Petty, an infectious disease specialist at the University of Michigan School of Medicine, said that she and her colleagues were agonizing over when and if to switch from the abundant monoclonal antibodies to the scarcer sotrovimab. Treating patients with monoclonal antibodies is preferred because it's more efficient, says Wolfe.
