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 aims to advance medical knowledge by studying people, either through direct interaction or through the collection and analysis of blood, tissues, or other samples. A clinical trial involves research participants. It follows a pre-defined plan or protocol to evaluate the effects of a medical or behavioral intervention on health outcomes. By taking part in clinical trials, participants not only play a more active role in their own health care, but they also can access experimental treatments and help others by contributing to medical research.
