WASHINGTON: The US National Institutes of Health said on Saturday it has halted a clinical trial to evaluate the safety and effectiveness of the malaria drug hydroxychloroquine for the treatment of hospitalised Covid-19 patients.
Earlier this week, the World Health Organization said testing of hydroxychloroquine in its large multi-country trial of treatments for Covid-19 patients had been halted after new data and studies showed no benefit. Trump had promoted the drug as a potential treatment, saying in March it could turn out to be “one of the biggest game-changers in the history of medicine” when used in combination with the antibiotic azithromycin.
