Gilead Sciences Inc (NASDAQ:GILD) shares jumped before the bell Monday after the drug manufacturer provided its experimental Ebola therapy for use in patients with coronavirus, according to a Reuters report late Friday. 

The company is working with Chinese officials to set up a study of the drug’s effectiveness against the virus, which has killed more than 200 people in the country and which the World Health Organization declared a public health emergency on Thursday. 

California-based Gilead is also testing its antiviral drug, remdesivir, against the virus. The scale of the threat continues to rise, as more than 10,000 people have been infected by the coronavirus around the world, Reuters reported.

Shares increased 4.3% to $65.91.
