Once again, the U.S. FDA giveth and it taketh away. Just a few days after expanding its approval for Gilead Sciences Inc.’s Veklury (remdesivir) to provide access to more people infected with COVID-19, the FDA essentially shut down the use of two monoclonal antibody (mAb) treatments Jan. 24 that had been authorized to treat mild-to-moderate COVID-19 infections – Regeneron Inc.’s Regen-Cov (Ronapreve in Europe), an antibody cocktail of casirivimab and imdevimab, and Eli Lilly and Co.’s bamlanivimab and etesevimab that are administered together.
