Outline of Final Research Achievements

We developed a new design for clinical trials comparing two treatments using multiple primary endpoints in which the number of necessary measurements is determined for each of the endpoints, taking into consideration both the cost and the individual power for each endpoint. We compared the efficiency of the proposed design with that of the conventional design using three variables: (1) the number of participants in the study, (2) the total number of measurements for all endpoints, and (3) the cost of enrolling the participants and obtaining the measurements for all endpoints. The conditions for the proposed design to be useful were found. We extended the proposed design to a group-sequential design.
