Remdesivir has become the first antiviral drug to be approved to treat coronavirus disease 2019 (COVID-19) in the US after showing promising results in a randomised, controlled trial of 1,063 patients sponsored by the US National Institute of Allergy and Infectious Diseases (NIAID). On 1 May, two days after the trial results were announced, the Food and Drug Administration issued an emergency use authorisation for the drug enabling it to be used for adults and children hospitalised with severe disease.
