 Pilot studies are often conducted before larger scale clinical trials to assess the feasibility of the trial and its components. These studies can be used to evaluate the safety of treatments or interventions, assess recruitment potential, and increase clinical experience with the study medication or intervention. They also serve as a prerequisite for larger scale trials by providing valuable information such as the number of participants needed, the time required to complete the trial, and the cost of the trial. Additionally, pilot studies can help to identify any potential problems with the design of the trial, such as recruitment difficulties or protocol violations, allowing them to be addressed before the main trial begins. Finally, pilot studies can help to ensure that the main trial will have a high chance of success.
