Abstract
We review the futility clinical trial design (also known as the non-superiority design) with respect to its emergence and methodologic developments over the last decade, especially in regard to its application to clinical trials for neurological disorders. We discuss the design's strengths as a programmatic screening device to weed out unpromising new treatments, its limitations and pitfalls, and a recent critique of the logic of the method.
