Of those participating, 86 patients were given a two-week course of three medicines: interferon beta-1b, a drug used to treat multiple sclerosis; HIV drugs lopinavir-ritonavir; and ribavirin, used to treat hepatitis.
A randomly-assigned control group of 41 people was just given the lopinavir-ritonavir combination.
Treatment began on average five days after symptoms started and all patients otherwise received standard care, including oxygen therapy.
Researchers then measured how long it took for a swab test for the virus to turn out negative.
They found that those taking all three medicines were able to clear the coronavirus in seven days on average (between five and 11 days) -- "significantly" shorter than the 12-day average for the control group.
Those on the three-drug regimen also saw a complete alleviation of their symptoms in an average of four days, compared to eight for the control group.
