The NIHR has launched a new Clinical Trials (CT) Toolkit website to help researchers navigate through the complex landscape of setting up and managing clinical trials in line with regulatory requirements. Based on the design of a tube map, the CT Toolkit uses an interactive colour-coded routemap to differentiate between legal and good practice requirements, and provides essential information at the ‘stations’ along the route giving the users an idea of the critical path for trial set-up and delivery.
