An experimental antiviral pill developed by Merck & Co. could halve the chances of dying or being hospitalized for those most at risk of contracting severe COVID-19, according to data that experts hailed as a potential breakthrough in how the virus is treated.
If it gets authorization, molnupiravir, which is designed to introduce errors into the genetic code of the virus, would be the first oral antiviral medication for COVID-19.
Merck and partner Ridgeback Biotherapeutics said they plan to seek U.S. emergency use authorization for the pill as soon as possible and to make regulatory applications worldwide.
