The scientific research and development process usually starts with an idea. Scientists then conduct experiments to explore and learn about this idea using data collected from this experiment. Some experiments are refined and repeated until a conclusion can be formulated, hence confirm or reject this idea. This follows an explore, then confirm thinking process.
On the other hand, most of the Phase II or III clinical trials are designed with a confirmatory objective. After this objective is reached, then clinical scientists will learn from clinical data collected in this study. Hence, the study design should start with a confirmatory step to determine if the primary objective is achieved and then followed by an exploratory step to learn from the study. This article discusses the stepwise process of study design, and provides examples of how this thinking process is applied in actual situations.
