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.
Clinical research is research that directly involves a particular person or group of people, or that uses materials from humans, such as their behavior or samples of their tissue.y taking part in clinical trials, participants can not only play a more active role in their own health care, but they can also access new treatments and help others by contributing to medical research. The NICHD is involved in all aspects of clinical trials and clinical research.
