A drug being tested by scientists at China's prestigious Peking University could not only shorten the recovery time for those infected, but even offer short-term immunity from the virus, researchers say.
"When we injected neutralising antibodies into infected mice, after five days the viral load was reduced by a factor of 2,500," said Xie. "That means this potential drug has (a) therapeutic effect."
The drug uses neutralising antibodies - produced by the human immune system to prevent the virus infecting cells - which Xie's team isolated from the blood of 60 recovered patients.
He added that the drug should be ready for use later this year and in time for any potential winter outbreak of the virus, which has infected 4.8 million people around the world and killed more than 315,000.
China already has five potential coronavirus vaccines at the human trial stage, a health official said last week.
More than 700 patients have received plasma therapy in China, a process which authorities said showed "very good therapeutic effects".
"However, it (plasma) is limited in supply," Xie said, noting that the 14 neutralising antibodies used in their drug could be put into mass production quickly.
Ebola drug Remdesivir was considered a hopeful early treatment for Covid-19 - clinical trials in the US showed it shortened the recovery time in some patients by a third - but the difference in mortality rate was not significant.
