The U.S. health regulator authorized a lower dose of Regeneron Pharmaceuticals’ Covid-19 antibody cocktail that can be given by injection, a move that could ease logistical challenges stemming from administering a higher dose intravenously.

The U.S. Food and Drug Administration gave an emergency use authorization to the antibody treatment developed by Vir Biotechnology and GlaxoSmithKline for treating mild-to-moderate Covid-19 in people aged 12 years and older.

The European Union’s drug regulator said on May 21 a Covid-19 antibody treatment developed by GlaxoSmithKline and Vir Biotechnology can be used to treat patients who are at risk of severe disease and do not need supplemental oxygen.

Eli Lilly and Co. will move a new Covid-19 antibody therapy to human trials targeting a coronavirus variant that was first found in South Africa, the U.S. drugmaker said.
