Q-Submission (Pre-Submission)
Voluntary mechanism to obtain FDA feedback before a formal premarket submission.
Definition
The Q-Submission Program lets sponsors request written feedback or a meeting with FDA on specific questions about a planned device study, submission, or test plan. Pre-Submissions are the most common Q-Sub type.What this means in practice
Used to de-risk study protocols, predicate selection, performance test plans, and AI/ML change control plans before investing in execution. Strong Pre-Subs reduce review cycles later.Examples
- A MedTech manufacturer submits a Q-Submission to get FDA feedback on the statistical analysis plan for a novel clinical trial prior to patient enrollment.
- A company developing an AI/ML powered diagnostic device uses a Pre-Submission to discuss its algorithm change control plan with the FDA to ensure compliance with the agency's evolving guidance on AI/ML in MedTech.
- Before conducting extensive biocompatibility testing, a device developer uses a Q-Submission to confirm with the FDA that the proposed test battery and materials are acceptable.
- •Misunderstanding the FDA's expectations for Q-Submission content can lead to unproductive interactions and delays.
- •Failing to clearly articulate specific questions in a Q-Submission may result in general feedback that does not address the sponsor's core concerns.
- •Submitting a Q-Submission too late in the development cycle may limit the ability to incorporate FDA feedback effectively.
- •Not adequately preparing for a Q-Submission meeting, such as failing to provide pre-read materials or clearly define meeting objectives, can diminish its value.
