From today, ivermectin is being investigated in the UK as part of the Platform Randomised Trial of Treatments in the Community for Epidemic and Pandemic Illnesses (PRINCIPLE), the world’s largest clinical trial of possible COVID-19 treatments for recovery at home and in other non-hospital settings. Led by the University of Oxford, PRINCIPLE is investigating treatments for people at more risk of serious illness from COVID-19 which can speed up recovery, reduce the severity of symptoms and prevent the need for hospital admission.
