How to Register a Drug with USFDA – A Complete Submission Guide
USFDA Drug Registration: The United States Food and Drug Administration (USFDA) regulates all pharmaceutical products entering the US market.
Drug manufacturers must comply with strict guidelines and submit complete documentation in CTD/eCTD format for approval.
Navigating the complex landscape of USFDA Drug Registration requires both technical knowledge and a strategic approach to regulatory compliance.
To ensure a successful USFDA Drug Registration, it is essential to follow FDA guidance documents and invest in eCTD software validation.”
This article about USFDA Drug Registration breaks down the process for ANDA, NDA, and DMF submissions with timelines and strategic tips.
🧰 Regulatory Bodies Involved for USFDA Drug Registration
- CDER – Center for Drug Evaluation and Research
- CBER – Center for Biologics Evaluation and Research
- OC – Office of Compliance
- ORA – Office of Regulatory Affairs
These bodies ensure quality, safety, and efficacy standards before granting marketing approval.
📦 Types of Submissions
1. NDA (New Drug Application)
Used for new chemical entities (NCEs). Requires:
- Full clinical trial data
- Nonclinical pharmacology
- Full CTD: Modules 1–5
2. ANDA (Abbreviated New Drug Application)
Used for generic drugs. Requires:
- Bioequivalence study
- No clinical data
- Reference Listed Drug (RLD)
3. DMF (Drug Master File)
Confidential documentation on:
- APIs
- Excipients
- Packaging materials
DMFs are not approved, but reviewed during NDA/ANDA linkage.
📑 Format – CTD / eCTD Requirements
USFDA mandates electronic submissions through eCTD (Electronic Common Technical Document) format.
Properly structuring your electronic documents is essential for a smooth USFDA Drug Registration process through the ESG portal.
Structure:
- Module 1 – Regional information
- Module 2 – Summaries
- Module 3 – Quality
- Module 4 – Nonclinical
- Module 5 – Clinical
Use FDA’s ESG Portal (Electronic Submission Gateway) for filing.
📋 Submission Timelines
| Submission Type | Standard Review | Priority Review |
|---|---|---|
| NDA | 10 months | 6 months |
| ANDA | ~10 months | N/A |
| DMF | Linked to main app | N/A |
Tip: For generics, DMF must be on Type II API level and available in FDA’s DMF list.
🧾 Filing Fees (2025)
| Application Type | Fee |
|---|---|
| NDA (clinical) | $4,211,000 |
| NDA (nonclinical) | $2,133,000 |

| DMF Submission | $78,000 |
Fees are revised annually in October.
📌 Common Deficiencies in Submissions
- Incomplete Module 3 (CMC Data)
- Non-standard BE protocols
- Missing validation data in analytical methods
- Incorrect electronic file structure in eCTD
🔍 Pre-submission Activities
- Pre-IND meeting for NDAs
- Controlled Correspondence for ANDAs
- Letter of Authorization (LOA) for referencing DMFs
Make use of Type A, B, and C meetings for scientific advice.
🧪 Post-Approval Requirements
- Annual Reports
- Field Alert Reports
- Labeling Changes
- REMS (Risk Evaluation and Mitigation Strategies) if required
- Inspection Readiness
Role of USFDA in Protecting Public Health
The US Food and Drug Administration (FDA) plays a crucial role in ensuring that only safe, effective, and high-quality drugs reach the American public.
The FDA’s Center for Drug Evaluation and Research (CDER) evaluates new drugs before approval, monitors marketed drugs for safety, and ensures good manufacturing practices (GMP) are followed.
Additionally, USFDA’s Office of Regulatory Affairs (ORA) oversees inspections, enforces regulatory compliance, and collaborates internationally on harmonizing global drug safety standards.
Types of Drug Applications Explained in Detail
🧪 1. Investigational New Drug (IND)
Before an NDA, clinical trials must be approved through an IND. This application includes:
- Animal pharmacology & toxicology data
- Manufacturing data
- Clinical protocols for Phase I–III trials
🧾 2. New Drug Application (NDA)
Used for brand-new chemical entities, biologics, or new dosage forms:
- Requires full preclinical and clinical study data
- Detailed Chemistry, Manufacturing, and Controls (CMC) information
- Risk mitigation plans (REMS) if applicable
💊 3. Abbreviated New Drug Application (ANDA)
Used for generic drugs:
- No need for full trials
- Must prove bioequivalence to the RLD (Reference Listed Drug)
- Often used by Indian generic manufacturers
🗂️ 4. Drug Master File (DMF)
- A confidential filing that supports API/Excipient/Container closure systems
- Filed in Type I–V categories (most common: Type II – drug substance)
- Must be referenced via Letter of Authorization (LOA)
Lifecycle of a USFDA Drug Registration
- Pre-submission Activities
- Pre-IND, Pre-NDA or Pre-ANDA meetings
- Submission of Controlled Correspondence
- Site inspection preparation
- Filing and Review
- Use of FDA’s ESG portal for eCTD uploads
- Technical screening (74-day letter for NDAs)
- FDA “Complete Response Letter” (CRL) if deficiencies exist
- Post-Approval
- CMC updates (annual reports)
- Labeling variations
- Adverse event reporting (MedWatch Form FDA 3500)
📤 eCTD Submission Platform – ESG Portal
The Electronic Submissions Gateway (ESG) is FDA’s centralized system for receiving regulatory submissions electronically. It requires:
- An ESG WebTrader account
- Digital certificate
- XML backbone (eCTD structure)
- Compliance with Module 1 US regional requirements
💡 Tip: Many Indian companies use global DMS platforms (like Extedo, LORENZ) to build and validate eCTDs before submitting via ESG.
💡 Tips for a Successful USFDA Submission
Companies planning a first-time USFDA Drug Registration should consider engaging with a regulatory consultant familiar with CDER requirements.
- Ensure no file corruption in eCTD modules
- Validate using FDA Validator tools
- Ensure CMC section is fully aligned with DMF (if referenced)
- Follow naming conventions strictly (uppercase/lowercase folder names matter)
📣 Common USFDA Meeting Types
- Type A – Urgent issues (e.g., clinical hold)
- Type B – Pre-IND, End-of-Phase meetings
- Type C – Any other discussion (labeling, trial design)
Meetings help resolve questions in advance and prevent rejections or delays.
