(Reuters) - Regeneron Pharmaceuticals Inc said on Tuesday its antibody cocktail was effective in preventing COVID-19 in people exposed to those infected with the new coronavirus, based on interim results from a late-stage study.
The two-antibody cocktail, REGEN-COV, caused a 100% reduction in symptomatic infection and roughly 50% lower overall rates of infection, based on an analysis of about 400 participants in the trial who had a household member with COVID-19.
