Shares of Gilead Sciences Inc rose 6% on Friday after its antiviral drug, remdesivir, became the first and only approved treatment for COVID-19 in the United States.
The U.S. health regulator’s approval on Thursday for its use in hospitalized patients came despite the World Health Organization last week saying the drug did not have a substantial effect on patients’ length of hospital stay or chances of survival in a global trial.
The U.S. Food and Drug Administration’s (FDA) backing signals its confidence in Gilead’s U.S.-based study results, which showed the drug was able to cut time to recovery in patients, Piper Sandler analyst Tyler Van Buren said in a client note.
Remdesivir has been available under an FDA emergency use authorization since May, after a study led by the National Institutes of Health showed it reduced hospital stays by five days.
The drug, given intravenously, could generate over $1 billion in sales during the second half of the year at the current case rate, analyst Van Buren said.

Shares of Gilead were up 5.67% at $64.11 before the bell.
