Medical Devices; 30-Day Notices and 135-Day PMA Supplement Review

Riepilogo

The Food and Drug Administration (FDA) is amending its regulations governing the submission and review of premarket approval application (PMA) supplements to allow for the submission of a 30-day notice for modifications to manufacturing procedures or methods of manufacture. Amendments are being made to implement revisions to the Federal Food, Drug, and Cosmetic Act (the act) as amended by the Food and Drug Administration Modernization Act of 1997 (FDAMA). FDA is publishing these amendments in accordance with its direct final rule procedures. Elsewhere in this issue of the Federal Register, FDA is publishing a companion proposed rule under FDA's usual procedures for notice and comment to provide a procedural framework to finalize the rule in the event the agency receives any significant adverse comment and withdraws the direct final rule.
