FDA Additional Information (AI) Response Support for Medical Devices
Has the US Food and Drug Administration (FDA) requested additional information about your medical device submission? The FDA Additional Information (AI) Response service from Cosmetic Compliance Nest helps medical device businesses review FDA questions, organise supporting documentation, and prepare structured responses to outstanding regulatory concerns.
An FDA Additional Information request may require clarification, further documentation, revised labelling, additional technical evidence, or explanations relating to a medical device submission. Responding effectively requires a clear understanding of each FDA question, the available supporting evidence, and the applicable submission requirements.
Our service helps you assess the request, identify the information needed to address individual questions, and prepare a response package based on the evidence and documentation supplied by your organisation.
What Is an FDA Additional Information (AI) Request?
An Additional Information (AI) request is a request from the FDA for further information or clarification during the review of a medical device submission. The exact terminology, process, and response requirements depend on the submission type and the FDA communication received.
For example, a 510(k) submission may receive questions concerning substantial equivalence, intended use, device characteristics, performance testing, biocompatibility, sterilisation, software, or labelling. The questions raised will depend on the device and the evidence already provided.
Each request should be reviewed carefully so that the response addresses the specific question, references appropriate supporting evidence, and avoids unsupported statements or inconsistencies with the original submission.
What Does Our FDA AI Response Service Cover?
- FDA Request Review: Review the FDA communication and identify the individual questions, requested documents, and stated response requirements.
- Question-by-Question Assessment: Organise each question into a structured response plan to help ensure that the requested points are addressed.
- Documentation Gap Identification: Identify missing information, unclear explanations, and potential evidence gaps based on the supplied documents.
- Technical Documentation Review: Review relevant device specifications, testing reports, technical files, and other supporting information within the agreed scope.
- 510(k) Substantial Equivalence Support: Where applicable, help organise explanations and supporting evidence related to the device comparison and substantial equivalence rationale.
- Testing and Performance Evidence: Review available evidence relating to performance, bench testing, biocompatibility, sterilisation, software, or other topics raised by the FDA.
- Labelling and IFU Review: Assess relevant proposed label or Instructions for Use changes where they relate to the FDA's questions.
- Draft Response Preparation: Help prepare clear, organised draft responses that reference the available supporting documentation.
- Response Consistency Check: Review the draft responses for consistency with the supplied evidence and other relevant submission materials.
- Supporting Document Organisation: Help organise relevant attachments, revised documents, and evidence references according to the agreed deliverables.
Testing, new studies, laboratory work, engineering changes, and the creation of new technical evidence are not automatically included in a response-preparation service. Any additional work must be assessed and agreed separately.

Documents and Information You May Need
Depending on your submission and the questions raised by the FDA, the following information may be requested:
- The complete FDA Additional Information request or official correspondence.
- The original submission and relevant submission sections.
- Device description, intended use, and indications for use.
- Device specifications and relevant technical documentation.
- Bench testing and performance testing reports, where applicable.
- Biocompatibility, sterilisation, or other supporting reports, where relevant.
- Software documentation, risk analysis, or cybersecurity documentation, where applicable.
- Proposed labels, packaging information, and Instructions for Use.
- Substantial equivalence comparisons and predicate device information, where applicable.
- Previous FDA correspondence and any response drafts already prepared.
The documents required will depend on the specific FDA questions. Not every item applies to every device or submission.
Important Considerations When Responding to FDA Questions
FDA response preparation should begin with a careful review of the official request, including the submission type, requested information, response format, and applicable deadline. Each question should be addressed using relevant evidence and accurate device information.
If the FDA identifies a gap that cannot be resolved using existing records, additional testing, technical investigation, revised documentation, or specialist input may be necessary. These activities should be identified early so that their feasibility and timing can be assessed.
For 510(k) submissions, the response should remain consistent with the device description, intended use, technological characteristics, and substantial equivalence rationale. The applicable submission pathway and FDA communication should guide the response strategy.
