London, June 5 (RHC)-- The first results from the world's largest randomised trial of drugs to treat COVID-19 patients could be available in early July, one of the scientists leading the UK-based study called Recovery said.

The first data from the study, which is testing a selection of existing drugs, is likely to come from a type of steroid called low-dose Dexamethasone and used to reduce inflammation, said Martin Landray, professor of medicine and epidemiology in the Nuffield Department of Population Health at the University of Oxford.

The trial has so far enrolled 11,000 patients ranging from one to 109 years of ages at 175 UK hospitals since it was set up in March, he told reporters at a briefing.

"There is unlikely to be a single big win" from the trials, which is why the project is testing several existing medicines to see if they might be able to be repurposed to help treat COVID-19, he said.

"At the moment we really don't have any treatments, so the first results will give us a guide," he said.
