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.
A clinical trial is a carefully designed study which tests the benefits and risks of a specific medical treatment or intervention, such as a new drug or a behavior change (e.g., diet).Once researchers have completed a rigorous screening and preclinical testing process, the company files an Investigational New Drug (IND) application with the U.S. Food and Drug Administration (FDA).
