We create different “what-if” scenarios under different assumptions about the drug effect and simulate data from such scenarios and apply the design. We then see if under a scenario that drug doesn’t work, the design indeed says that the drug doesn’t work. Or, under a scenario that drug works, the design says that it works. We simulate under such scenarios thousands if not millions of times and check whether the design performs as required. This creates a new process of developing a study design and is a framework that allows fully vetting the design and challenging assumptions. This is especially important in Complex Innovative Designs. The operating characteristics of such designs can only be evaluated through intensive simulations to ultimately develop the optimal design that will answer more questions more efficiently and in less time. In this presentation, we will start with general principles and key steps for simulation guided clinical trial design. We will follow with a simulation case study that illustrates the principles, key steps of setting the scenarios, and the operating characteristics of different candidate designs that allow the selection of the most appropriate design for the objectives of the trial.
