Adaptive Design Clinical Trials. Treatment options that are not working well can be removed from the trial as well. Other Innovative Design approaches at the Trial or Program Level Is adaptive randomization always better than traditional fixed-schedule randomization? Which procedures should be used and under which circumstances? What special considerations are required for adaptive randomized trials? An adaptive design clinical trial—defined to be a trial with any preplanned early examination of the data, including any monitoring of the data by a data monitoring and ethics committee (DMEC) where it is clear that there had been or there is a planned formal analysis of the data. Michael John Grayling and Graham Mark Wheeler. Adaptive Clinical Trial Design – Case Studies. In recent times, there has been an increasing interest in adaptive designs for clinical trials. In traditional clinical trials, key elements such as primary endpoint, clinically meaningful treatment difference, and measure of variability are pre-specified during planning in order to design the study. Adaptive clinical trial designs, those that use interim data analysis to amend trials, have been recognized for more than a decade as a way to increase trial efficiency by means of shorter duration, fewer participants, and, in some adaptive designs, increased probability of demonstrating an effect of the drug if one exists.
