The term âfutilityâ is used to refer to the inability of a clinical trial to achieve its objectives. In particular, stopping a clinical trial when the interim results suggest that it is unlikely to achieve statistical significance can save resources that could be used on more promising research.

These studies also may show which medical approaches work best for certain illnesses or groups of people.Clinical trials produce the best data available for health care decisionmaking.linical trials are one of the final stages of a long and careful research process.
