Why Pre-Submission Meetings Matter

FDA pre-submission meetings—whether Type A, B, or C—are pivotal for shaping the direction of a drug, biologic, or device development program. These sessions offer sponsors the chance to receive guidance, resolve issues, and align expectations with regulators early in the process. However, to derive value from these interactions, sponsors must understand how to conduct themselves, what to avoid, and how to present a cohesive regulatory strategy.

Missteps in these meetings can lead to miscommunication, delays, or even incorrect assumptions about the regulatory pathway. Conversely, a well-prepared sponsor can build trust with the agency and accelerate their submission timelines.

Top 5 Dos for Pre-Submission Interactions

Let’s begin with the key practices every sponsor should adopt:

Do Submit a Clear, Focused Briefing Package: Frame questions with background context and highlight any data limitations. The FDA appreciates clarity, not vagueness.

Do Align Internally Beforehand: Ensure clinical, CMC, nonclinical, and regulatory teams agree on data interpretations and proposed strategies.

Do Rehearse the Meeting: Conduct mock meetings internally to fine-tune responses and test the team’s preparedness.

Do Treat the Meeting as Official Record: Everything discussed is subject to minutes, so choose language carefully and stay on-message.

Do Follow Up Professionally: Review FDA-issued minutes promptly and request corrections if warranted within the 7-day window.

Top 5 Don’ts in Pre-Submission Interactions

Equally important are the actions you should avoid at all costs:

Don’t Ask Hypothetical or Vague Questions: Avoid “what if” scenarios that lack a defined context or data support.
Don’t Introduce New Data During the Meeting: FDA reviewers base their responses on submitted materials—surprises are counterproductive.
Don’t Challenge Feedback in the Meeting: If disagreement arises, follow up post-meeting with a formal response rather than arguing live.
Don’t Let Multiple Functions Speak Uncoordinated: Designate one spokesperson to prevent confusion and duplication.
Don’t Exceed Allotted Time: Respect the schedule. Long-winded explanations limit the opportunity for valuable discussion.

Real-World Example: A Sponsor’s Costly Misstep

In one pre-NDA Type B meeting, a sponsor submitted a strong briefing package but presented new stability data during the teleconference that wasn’t included in the submission. The FDA refused to discuss it, stating that review of new information required a formal submission. This caused a six-week delay, as the sponsor had to resubmit and request another meeting.

This highlights the importance of fully incorporating all intended discussion materials within the original package.

The Role of Regulatory Affairs in Ensuring Meeting Success

Regulatory Affairs (RA) acts as the central coordinator of all meeting activities, including:

Scheduling meetings and preparing requests
Managing briefing document creation and submissions via eCTD
Running internal rehearsal sessions
Serving as the spokesperson or moderating the session
Ensuring timely review of FDA minutes and corrections

RA’s leadership helps mitigate risks and ensures regulatory expectations are interpreted correctly.

Briefing Document Template: What to Include

Cover Letter: States meeting type, objective, and product overview
Proposed Agenda: Itemized discussion points with time allocation
List of Questions: Specific, targeted, and backed by rationale
Supporting Data: Summary tables, module references, safety summaries
Appendices: Draft protocols, relevant regulatory precedents

Formatting should follow FDA eCTD specifications and be placed in Module 1.6.1.

Case Study: Successful Pre-IND Meeting

A clinical-stage company developing a generic nasal spray scheduled a Type B pre-IND meeting to clarify:

Whether a comparative PK study with U.S. reference product was sufficient
If additional nonclinical safety data were needed
Strategies for meeting nasal deposition equivalence standards

Due to well-formulated questions and cross-functional preparedness, the FDA provided favorable responses. The sponsor avoided a costly 6-month toxicology study and proceeded directly to a pivotal BE study.

Global Best Practices for Regulatory Interactions

While FDA provides structured Type A/B/C meeting formats, other agencies like the EMA and PMDA have similar engagement protocols. For example:

EMA uses Scientific Advice Procedures (SAP) with pre-defined question structures
PMDA requires pre-consultation meetings before formal evaluations

Sponsors pursuing global approvals should coordinate agency interactions using a harmonized global development plan.

Conclusion: Discipline and Preparation Drive Success

Pre-submission interactions with the FDA are opportunities to gain clarity, prevent errors, and accelerate development. But the quality of these engagements depends entirely on how well they’re prepared and managed. Sponsors should treat these meetings as regulatory milestones, with clear structure, discipline, and documented execution.

By adhering to the dos and avoiding the don’ts, regulatory teams can build strong agency rapport and ensure their development plans are set on a compliant and efficient path.
