title: Regulatory issues unique to clinical trials on periodontal diagnostic methods and devices.
abstract: A wide variety of in vitro diagnostic products have been proposed for use in patients with periodontal disease. The Food and Drug Administration (FDA) review focuses on three important issues. First, the product must exhibit acceptable analytical performance (accuracy, precision, analytical sensitivity, and analytical specificity). Second, the effectiveness of the device must be clearly defined. The studies required to establish this will depend largely on the proposed intended use of the product. At a minimum, clinical or diagnostic sensitivity and specificity should be established. Finally, the product must meet the labeling requirements for in vitro devices. These requirements outlined in CFR 809.10(b) are comprehensive and cover 15 key elements including information about the principles of the analytical method; handling of instruments, reagents, and patient samples; test limitations; and test performance. Applicants developing products for any in vitro diagnostic device are encouraged to review the labeling regulations along with other divisional and office guidance material to help in defining the submission requirements. The FDA is willing to meet and work with companies prior to and during preclinical and clinical trials to assist in the development of appropriate study protocols.
