How to Prepare a USFDA Pre-IND Meeting Package
Before initiating clinical trials for a new drug in the United States, sponsors often engage with the U.S. Food and Drug Administration (USFDA) through a Pre-Investigational New Drug (Pre-IND) Meeting.
This meeting offers a strategic opportunity to gain feedback from the FDA early in the drug development process, helping mitigate regulatory risks and accelerate approval timelines.

This comprehensive guide explains how to prepare a USFDA Pre-IND meeting package, including timelines, format, structure, submission procedures, and expert tips to optimize the outcome of your engagement with the FDA.
🧠 What is a USFDA Pre-IND meeting?
A Pre-IND Meeting is an early communication between a drug sponsor and the Center for Drug Evaluation and Research (CDER) at the USFDA. It allows the sponsor to:
- Present their drug development plan
- Seek FDA guidance on clinical trial design
- Discuss regulatory expectations
- Identify potential issues before formal IND submission
Pre-IND meetings are voluntary but highly recommended, especially for:
- First-in-human trials
- Complex or novel drug candidates
- Sponsors unfamiliar with FDA expectations
📌 Benefits of a USFDA Pre-IND meeting
- Reduce the chance of IND rejection
- Understand data expectations and reduce clinical burden
- Clarify CMC requirements early
- Identify regulatory gaps and avoid unnecessary studies
- Discuss waivers, special designations, or fast-track options
🗂 When Should You Request a USFDA Pre-IND meeting?
The optimal time is:
- Before submitting the Investigational New Drug (IND) application
- After generating sufficient nonclinical, CMC, and initial clinical plans
- 60–90 days before your proposed IND submission timeline
FDA recommends submitting the Pre-IND meeting request at least 60 days before the intended meeting date.
📄 What Should a USFDA Pre-IND meeting Package Contain?
A well-organized Pre-IND meeting package increases the chance of receiving helpful feedback from the FDA.

- Include meeting request type (Pre-IND)
- Brief overview of the drug candidate
- Proposed agenda and objectives
📁 2. Background Information
- Company name and contact details
- Brief description of the drug (molecular structure, MoA)
- Proposed indication
- Overview of development history (preclinical & regulatory)
🧪 3. CMC (Chemistry, Manufacturing & Controls)

💼 How to Frame Effective Pre-IND Questions
Examples:
❓ Is the proposed 28-day rodent study sufficient to support FIH trials?
❓ Does the FDA agree with the exclusion of a chronic toxicity study for the proposed indication?
❓ Is the justification for dose escalation strategy acceptable?
✅ Tips:
- Avoid overly broad questions
- Align each question with a section in your package
- Don’t exceed 10 questions unless strongly justified
🧪 IND-Enabling Studies Overview
Before submitting an IND or requesting a Pre-IND meeting, sponsors should ideally complete:
| Study Type | Purpose |
|---|---|
| Acute Toxicity | Dose range determination |
| Repeat Dose | Sub-chronic toxicity |
| Genotoxicity | Chromosomal damage analysis |
| Safety Pharmacology | Cardiovascular, CNS, respiratory systems |
| PK/ADME | Absorption, metabolism, excretion |
🧩 Related Regulatory Programs to Discuss
- Fast Track Designation
- Breakthrough Therapy
- Orphan Drug Designation
- 505(b)(2) Considerations
- Pediatric Study Plan (PSP)
These can be addressed as agenda items if applicable to your development strategy.
💬 What Happens After the Pre-IND Meeting?
- Meeting Minutes: FDA provides official minutes within 30 days
- Follow-Up Actions: Incorporate FDA feedback into your IND
- IND Submission: You can proceed with confidence on the agreed trial design and documentation
❓ FAQs
Q1. Is a Pre-IND meeting mandatory?
No, but highly recommended for novel drugs and first-time sponsors.
Q2. Can I request clarification after the meeting?
Yes, minor clarifications can be requested via the RPM post-meeting.
Q3. Are Pre-IND meetings free?
Yes, currently, no separate user fee applies.
✅ Conclusion
A successful USFDA Pre-IND meeting is one of the most strategic steps in early drug development.
It can de-risk your program, clarify regulatory expectations, and ultimately save time and cost during clinical development.
Preparation, scientific rigor, and framing the right questions are essential to get the most value from this opportunity.
