COLUMNS: Psychopharmacology

The goal of early proof of concept studies, typically involving a small number of subjects and more latitude in statistical requirements, is to provide evidence that a drug is likely to be successful in later stages of drug development. Although often not published, such studies allow drug developers to make “Go/No Go” decisions about proceeding with larger, more expensive studies. (Journal of Psychiatric Practice 2014;20:59–60)
