The NIH COVID-19 Treatment Guidelines Panel, an independent panel of national experts, recently recommended against the use of bamlanivimab and etesevimab (administered together) and REGEN-COV (casirivimab and imdevimab) because of markedly reduced activity against the omicron variant and because real-time testing to identify rare, non-omicron variants is not routinely available. While the drug had shown mixed results in studies as a treatment for hospitalized patients, it has proved surprisingly effective, according to Gilead's data, at treating patients early in the course of the disease. Also, a rapid rise in omicron infection rate across the country has affected transportation staff, which has contributed to these supply shortages.
