Omicron may sideline two leading drugs against COVID-19

The rapidly-spreading omicron variant may soon leave U.S. doctors without two of the standard treatments they’ve used to fight COVID-19
WASHINGTON -- As strained U.S. hospitals brace for a new surge of COVID-19 cases caused by the fast-spreading omicron variant, doctors are warning of yet another challenge: the two standard drugs they’ve used to fight infections are unlikely to work against the new strain.
For more than a year antibody drugs from Regeneron and Eli Lilly have been the go-to treatments for early COVID-19, thanks to their ability to head off severe disease and keep patients out of the hospital.
But both drugmakers recently warned that laboratory testing suggests their therapies will be much less potent against omicron, which contains dozens of mutations that make it harder for antibodies to attack the virus. And while the companies say they can quickly develop new omicron-targeting antibodies, those aren’t expected to launch for at least several months.
A third antibody from British drugmaker GlaxoSmithKline appears to be the best positioned to fight omicron. But Glaxo’s drug is not widely available in the U.S., accounting for a small portion of the millions of doses purchased by the federal government and distributed to states.
