July 29, 2011 — The U.S. Food and Drug Administration (FDA) this week issued draft guidance that clarifies when changes or modifications to a previously cleared 510(k) device require a new premarket submission.
The 510(k) process is the most common review path to market for lower-risk medical devices. To legally market a device, manufacturers must submit a premarket notification, or 510(k), demonstrating that the new or modified product is substantially equivalent to another legally marketed medical device.
Manufacturers often make changes or modifications to a device after FDA clearance such as incorporating new technology or upgrading certain aspects of the device. Many changes do not require a 510(k) submission. But when the changes could significantly affect the product’s safety or effectiveness or constitute a major change to the intended use of the device, another 510(k) must be submitted.
“We are making the regulatory process for medical devices less challenging by better describing our expectations,” said Jeffrey Shuren, M.D., director of the FDA’s Center for Devices and Radiological Health. “In particular, manufacturers can continue to make innovative improvements to their devices and better plan for any updated submissions. This saves time and money.”
The draft guidance clarifies the kinds of changes that trigger the need for a new submission, such as specific kinds of labeling changes, changes to the technology used in the device, changes in performance specifications, manufacturing changes, and changes in the materials used in the manufacture of the device.
This draft guidance is one of 25 action items listed in the FDA’s Plan of Action for Implementation of 510(k) and Science Recommendations launched in 2011 to enhance predictability, consistency, and transparency of the FDA’s premarket review programs.
