Like other RNA viruses, SARS-CoV-2 depends on an RNA-dependent RNA polymerase (RdRp) enzyme complex for genomic replication, which can be inhibited by a class of drugs known as nucleoside analogues.  Remdesivir (GS-5734) is an adenosine triphosphate analogue first described in the literature in 2016 as a potential treatment for Ebola. Broad antiviral activity of remdesivir is suggested by its mechanism of action, and to date, it has demonstrated in vitro activity against the Arenaviridae, Flaviviridae, Filoviridae, Paramyxoviridae, Pneumoviridae, and Coronaviridae viral families. Remdesivir activity against the Coronaviridae family was first demonstrated in 2017, leading to considerable interest in remdesivir as a possible treatment for COVID-19. Remdesivir was confirmed as a non-obligate chain terminator of RdRp from SARS-CoV-2 and the related SARS-CoV and MERS-CoV, and has been investigated in multiple COVID-19 clinical trials.  After initially being granted an FDA Emergency Use Authorization (EUA) on May 1st, 2020, remdesivir was fully approved by the FDA for the treatment of COVID-19 on October 22, 2020. Remdesivir is currently marketed under the trademark name VEKLURY by Gilead Sciences Inc. Remdesivir was also approved by the European Commission on July 3, 2020. Remdesivir in combination with [baricitinib] for the treatment of COVID-19, was granted an FDA Emergency Use Authorization on November 19, 2020."}]
