Evaluation of Automatic Class III Designation (De Novo) Summaries
The Food and Drug Administration Modernization Act of 1997 (FDAMA) added the "De Novo" classification option as an alternate pathway to classify certain new devices that had automatically been placed in Class III due to lack of a predicate.
The De Novo process applies to low and moderate risk devices that have been classified as class III because they were found not substantially equivalent (NSE) to existing devices. Applicants who receive this determination may request a risk-based evaluation for reclassification into class I or II within 30 days of receipt of an NSE determination. Devices that are classified through the De Novo process may be marketed and used as a predicate for future Premarket Notification [510(k)] submissions.
FDA has begun releasing De Novo Summary documents for devices granted market authority through the De Novo process. The De Novo Summary is intended to present an objective and balanced summary of the scientific evidence that served as the basis of the decision to grant a de novo petition. The Summary outlines how FDA determined that the device for which a petition is granted is low to moderate risk and that general and/or special controls provide reasonable assurance of safety and effectiveness. The De Novo Summary also serves as a resource on the types of information necessary to support substantial equivalence for device manufacturers that may wish to use the de novo device as a predicate for future 510(k) submissions.
