About the FDA's Formal Dispute Resolution Process

FDA regulations provide a mechanism for those seeking regulatory approval of a drug product through a New Drug Application (NDA) to obtain formal review of any Agency decision through a Formal Dispute Resolution process by raising the matter with the supervisor of the employee who made the decision. If the issue is not resolved at the primary supervisory level, the applicant may request that the matter be reviewed at the next higher supervisory level. This process may continue through the Agency's chain of command, through the Centers to the Commissioner of Food and Drugs. The Formal Dispute Resolution process exists to encourage open, prompt discussion of scientific (including medical) disputes and procedural (including administrative) disputes that arise during the drug development, new drug review, generic drug review, and post-marketing oversight processes.
