Abstract

The COVID-19 pandemic progresses unabated in many regions of the world. An effective Antiviral against SARS-CoV-2 that could be administered orally for use following high-risk exposure would be of substantial benefit in controlling the COVID-19 pandemic. Herein, we show that MK-4482, an orally administered nucleoside analog, inhibits SARS-CoV-2 replication in the Syrian hamster model. The inhibitory effect of MK-4482 on SARS-CoV-2 replication was observed in Animals when the drug was administered either beginning 12 hours before or 12 hours following Infection in a high-risk exposure model. These data support the potential utility of MK-4482 to control SARS-CoV-2 Infection in humans following high-risk exposure as well as for treatment of COVID-19 patients.
