The FDA’s Q-Submission Program (as updated in May 2025) represents one of the most powerful tools available to medical device developers seeking to de-risk regulatory pathways and accelerate time-to-market. For companies navigating complex device classifications, novel technologies, or uncertain regulatory requirements, the strategic use of Q-Submissions can mean the difference between smooth approval processes and costly delays.

At Biomedical Statistical Consulting® (BSC®), we’ve supported hundreds of successful FDA submissions over our 35+ years of regulatory biostatistics expertise. Our experience with Q-Submissions spans from early-stage Pre-Subs for breakthrough orthopedic and spine devices to complex Study Risk Determinations for AI-powered diagnostics.

What Is the Q-Submission (Q-Sub) Program?

The Q-Submission Program enables medical device companies to seek feedback and request meetings with the FDA before formally submitting marketing or investigational applications. These touchpoints can lead to more efficient development and review processes for new medical devices.

Q-Sub types include:

• Pre-Submission (Pre-Sub): Request written feedback on specific questions before an intended submission. ~70 days target response.

• Submission Issue Request (SIR): Get input on resolving issues flagged in a hold letter on an open submission. 21–70 days.

• Study Risk Determination: Ask FDA to determine if a proposed clinical study is significant risk, nonsignificant risk, or exempt. Typically within 90 days.

• Informational Meeting: Share information with FDA with no expectation of feedback. Typically within 90 days.

• PMA Day 100 Meeting: Review status of an original PMA ≤100 days after FDA files the application.

When NOT to Use the Q-Sub Program

You should not submit a Q-Sub if you only need administrative clarifications, your question is about device classification (use a 513(g) instead), your inquiry relates to an active review, the topic is a formal appeal, or the request involves Emergency Use Authorization.

Strategic Timing Considerations

Early Engagement: The most successful companies use Q-Submissions as part of a broader regulatory strategy from the earliest stages of device development. Consider submitting a Pre-Sub during the design control phase, particularly when your device incorporates novel technologies, AI/ML algorithms, or addresses unmet clinical needs.

Clinical Trial Planning: For devices requiring clinical data, submit Pre-Subs 6–12 months before planned study initiation.

Breakthrough Device Integration: Companies pursuing Breakthrough Device Designation should coordinate Q-Sub timing with their designation request.

Common Pitfalls and How to Avoid Them

Question Formulation Errors: Many companies submit overly broad questions. Structure questions around specific regulatory pathways, predicate device comparisons, or particular aspects of your development plan.

Documentation Gaps: Ensure your Q-Sub includes sufficient technical detail. Include comprehensive device descriptions, intended use statements, preliminary design information, and any relevant preclinical data.

Key Takeaways for a Successful Q-Sub

• Be Clear and Specific: Identify your device, intended use, and key questions

• Limit the Scope: FDA recommends focusing on no more than 3–4 substantial topics per submission

• Plan Ahead: Pre-Subs are best submitted well before clinical studies begin

• Follow Documentation Best Practices: Include a cover letter with detailed contact info and a clear request type

• Leverage Electronic Submissions: Use the CDRH Portal or FDA Electronic Submission Gateway

• Keep Records: All Q-Subs are confidential within the bounds of law

Updates in 2025

The May 2025 guidance aligns with FDA’s ongoing efforts under MDUFA V, clarifies the boundaries of Q-Sub versus other communication pathways, and provides enhanced examples of well-structured questions to maximize FDA engagement.

Conclusion

Getting FDA feedback early and often through the Q-Submission Program represents one of the smartest investments medical device companies can make in their regulatory strategy. Whether you’re developing breakthrough spinal implants, AI-powered diagnostics, or complex combination products, the Q-Submission pathway can provide the regulatory clarity and confidence needed to move forward decisively.
