| Outline of Final Research Achievements |
Many recent clinical trials for evaluating efficacy and safety of new interventions include multiple objectives, especially in medical product development. There are advantages of clinical trials with multiple objectives over trials with a single objective saving time and resources and more completely characterizing the intervention effects. However, such clinical trials require conducting a number of statistical tests and analyses associated with multiple objectives, and then, complex multiplicity or multiple testing problems occur. In this project, our team has conducted research on the design and analysis of such clinical trials, especially focusing on group-sequential and adaptive designs for clinical trials with multiple objectives, including design modification during trials
