Merck seeks first U.S. authorization for COVID-19 pill

Merck & Co Inc said on Monday it has applied for U.S. emergency use authorization for its drug to treat mild-to-moderate patients of COVID-19, putting it on course to become the first oral antiviral medication for the disease. An authorization from the U.S. Food and Drug Administration could help change clinical management of COVID-19 as the pill can be taken at home. The treatment, molnupiravir, cut the rate of hospitalization and death by 50% in a trial of mild-to-moderately ill patients who had at least one risk factor for the disease, according to data released earlier this month.
