Antiviral drug remdesivir has 'clear-cut' power to fight coronavirus, say US experts
There is "clear-cut" evidence that a drug can help people recover from the coronavirus, say US officials.
Remdesivir cut the duration of symptoms from 15 days down to 11 in clinical trial at hospitals around the world.
The full details have not been published, but experts said it would be a "fantastic result" if confirmed, but not a "magic bullet" for the disease, BBC News reports.
A drug would have the potential to save lives, ease pressure on hospitals and allow parts of lockdown to be lifted.
Remdesivir was originally developed as an Ebola treatment. It is an antiviral and works by attacking an enzyme that a virus needs in order to replicate inside our cells.
The trial was run by the US National Institute of Allergy and Infectious Diseases (NIAID) and 1,063 people took part. Some patients were given the drug while others received a placebo (dummy) treatment.
Dr Anthony Fauci who runs the NIAID said: "The data shows remdesivir has a clear-cut, significant, positive effect in diminishing the time to recovery."
He said the results prove "a drug can block this virus" and were "opening the door to the fact that we now have the capability of treating" patients.
