This document summarizes the FDA's Application Integrity Policy (AIP), which was established in 1991 in response to fraud in generic drug applications. The AIP allows the FDA to defer review of any application where they have questions about the reliability of the data, until those questions are resolved. Companies that fall under the AIP must cooperate with investigators, identify wrongdoers, conduct an internal review, and submit a corrective action plan signed by the CEO to address procedures and controls to prevent future issues. Few companies have survived being placed on the AIP, as it often coincides with criminal prosecution and civil litigation that can damage a company.
