International Clinical Trials Day: A conversation with Prof Martin Landray

International Clinical Trials Day (ICTD) is commemorated worldwide on the 20th of May, in recognition of day on which James Lind started, what is widely believed to be the first randomized clinical trial, in 1747.1,2 In search of a treatment for Scurvy, he recruited 12 subjects aboard the HMS Salisbury of the British Royal Navy fleet for his “fair test”, assigning two men to each of six different daily treatments for a period of fourteen days.2

First launched in 2005, ICTD is also an opportunity to celebrate the achievements of clinical trialists and vitally, raise awareness of clinical trials and the need for randomized evidence.1 There has never been a greater need for randomized evidence than right now. In view of this, I’m delighted to have spoken with Professor Martin Landray, co-chief investigator of the RECOVERY trial, Professor of Medicine & Epidemiology at the Nuffield Department of Population Health, and Deputy Director at the Big Data Institute, University of Oxford, UK. We spoke about the incredibly successful RECOVERY trial,3 adaptive platform trials and the Good Clinical Trials Collaborative.4

I’m very grateful to Prof Landray for his time and insights, and I hope you learn from this hugely educational vlog as much as I did.
