Scientists working on the trial said that patients who received the drug, called remdesivir, had almost a third of the recovery time than those who received a placebo.
Abdel Babiker, professor of epidemiology and medical statistics at UCL, told the BBC Radio 4 Today program: “These are very encouraging results from the first large-scale randomized trial to report on any treatment for Covid- 19. “
He said the group of adults admitted to hospital with advanced coronavirus recovered at a “much faster” rate when they were treated with the drug.
More than 1,000 patients worldwide have been enrolled in the Covid-19 adaptive therapy trial, including 46 from the UK. The trial began in early April.
Meanwhile, 86 other cases of coronavirus were confirmed yesterday in the county, including 10 in the city of Derby.
The number of deaths in Derby and Burton hospitals is now 366.
The number at Chesterfield Royal Hospital is still 73.
