eCTD v4.0 Gap Analysis + Document Prep: How ECTD Pharma Helps You Avoid Costly Rejections

2026 Is Coming — And Most Teams Are Guessing

January 1, 2026: FDA requires eCTD v4.0. One bad PDF. One broken link. One missing bookmark. → Technical rejection. → Weeks of rework. → Delayed approval.

We’ve seen it:

80% of 2025 pilot issues were document-related. (FDA ESG Validation Trends, Q3 2025)

At ECTD Pharma, we’ve completed 12+ v4.0 gap analyses and document prep projects in 2025. Result: No client has had a technical rejection after our review.

Not magic. Just thorough, practical, human-reviewed work.

How It Works — Step by Step

1. Gap Analysis

We review every file against FDA v4.0 rules:

• Broken links?

• Missing study tags?

• Non-compliant PDFs?

You get:

• Clear report (PDF + Excel)

• Prioritized fixes with out strict traffic light system

• Risk level (low/medium/high)

2. Document Preparation

We fix what’s broken:

Task	Why It Matters	How We Do It
PDF Compliance	Must be PDF/A-3b	Convert + validate
Bookmarks	FDA expects hierarchy	Auto-build + QA
Hyperlinks	Must work in v4.0	Rebuild with stable URIs
Metadata	Required for lifecycle	Add study tags, keywords
Searchable Text	No scanned images	OCR + verify

You get:

• Clean, clickable PDFs

• Validation-ready files

• ESG test report (we run a mock)

Real Example: What We Fixed for a Client

Client: Small US biotech (IND resubmission) Problem:

• 38 PDFs

• 112 validation warnings

• Broken hyperlinks, missing bookmarks

Our Fix (9 days):

1. Gap report → 112 issues mapped

2. Rebuilt all PDFs + hyperlinks

3. Ran mock v4.0 submission in ESG

Result:

ESG passed with 3 minor warnings (fixed same day). Client: “Saved us from a 3-week delay.”
