Handling FDA Additional Information Requests (AI Requests) in 510(k) Submissions
AI requests pause 510(k) review timelines until complete responses are submitted, and submissions requiring multiple AI cycles average 200+ FDA days—double the standard review goal. Understanding what triggers AI requests (missing data, performance testing gaps, software deficiencies, biocompatibility issues) and crafting thorough, well-organized responses is critical to avoiding delays and NSE decisions.
