Covid-19 treatment: Gilead Sciences urged to study drug that showed promise with cats

Activists are calling on the pharmaceutical firm Gilead Sciences to study a drug for the treatment of Covid-19 that showed promise in curing cats of a coronavirus.

The drug, called GS-441524, is chemically related to remdesivir, an antiviral also made by Gilead, and one of the only treatments to successfully shorten the duration of Covid-19 recovery.
