FDA Additional Information Request Response

Receiving an Additional Information Request (also known as an AI Request or Hold Letter) from the FDA is a common yet critical juncture in the medical device clearance process. With about two-thirds of submissions encountering this hurdle, it's a scenario many companies face, yet it remains a pivotal moment that can significantly impact your business's future.

Once you’ve been issued a Hold Letter, you will have an opportunity to meet with FDA shortly thereafter. You will then have 180 calendar days to respond. If you don’t respond in time, your 510(k) will be deleted and you will need to re-submit, restarting the original 510(k) clock.

We understand the complexities and high stakes involved in responding to FDA's AI Requests, especially when they pertain to the rapidly evolving fields of Artificial Intelligence/Machine Learning (AI/ML) and cybersecurity within medical devices.

A timeline showing showing the 510(k) process and typical interactions between the FDA and the manufacturer. The 510(k) clock pauses once the FDA hold letter has been issued. We can help develop an effective response to Hold Letters. We have especially deep expertise related to major findings related to cybersecurity and AI/ML models.
