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.
For patients, participation in a clinical trial is voluntary. Common reasons for joining a clinical trial include: playing a more active role in your own health care; gaining access to innovative treatments before they become widely available; and helping others by contributing to advancements in medical research.
