eCTD v4.0: What Life Sciences Companies Need to Know Before the 2028 Deadline

As regulatory authorities around the world move toward full adoption of eCTD v4.0, life sciences companies must begin preparing now. With the FDA supporting eCTD version 4.0 submissions for new applications from September 16, 2024, and a global mandate approaching by 2028, the shift from eCTD v3.2.2 to v4.0 marks a critical turning point for the industry. 

In this guide, we explore what is changing in eCTD v4.0, how to navigate the transition, and the benefits and challenges life sciences companies can expect—along with key strategies to stay compliant and ahead of the curve. 

 

From Paper to Digital: The Evolution of eCTD Submissions 

What began as a paper-based submission model in the 1980s evolved dramatically with the creation of the Common Technical Document (CTD) by ICH in 1997. The original eCTD format took hold in the early 2000s, with eCTD v3.2.2 becoming the standard in 2008. 

Now, eCTD v4.0 introduces a more intelligent, data-driven regulatory submission format built for global harmonization, enhanced lifecycle management, and more flexible communication between sponsors and agencies. 

 

What’s New in eCTD v4.0? 

📂 A Data-Driven Submission Format 

Unlike its predecessor, eCTD v4.0 introduces a flat structure using controlled vocabularies, sender-defined keywords, and Context of Use terminology. This change allows for more customizable document organization and streamlined regulatory submissions. 

🔄 Dynamic Document Lifecycle Management 

With the use of Object Identifiers (OIDs) and Universally Unique Identifiers (UUIDs), sponsors can now reuse documents across submissions and applications without needing to duplicate or reformat content. 

🌍 True Global Harmonization 

eCTD 4.0 supports a single submission format across all product types and global regions—including drugs, biologics, medical devices, food additives, cosmetics, and more. This eliminates regional discrepancies and minimizes software update requirements. 

 

Key Features and Functional Improvements 

• Two-way communication with regulatory bodies (planned in future versions) 

• Grouped submissions based on product or regulatory activity 

• Reduced reliance on hierarchical file structures 

• Ability to assign document priority and grouping 

• More accurate metadata editing without file resubmission 

• Enhanced granularity and flexibility in submission content 

• Greater reuse of previous submissions for faster reviews 

These enhancements make eCTD version 4.0 more adaptable and efficient for both sponsors and regulatory authorities. 

 

Technical & Regulatory Benefits of eCTD v4.0 

✅ For Regulatory Affairs Teams: 

• Faster submission turnaround 

• Easier compliance with FDA, EMA, and global eCTD standards 

• Simplified updates to existing submissions 

✅ For IT and Publishing Teams: 

• Less dependency on structural updates 

• Compatibility with more intelligent document management systems 

• Future-forward system design that reduces administrative overhead 

However, this transition also introduces challenges. Software upgrades, metadata planning, and team training are all essential for a successful shift. 

 

Challenges Companies Face When Transitioning 

• Need for new tools that support UUIDs and OIDs 

• Internal alignment on sender-defined keywords 

• Training staff in new submission protocols 

• Conducting gap analyses and system validations 

• Staying current on FDA eCTD submission standards and timelines 

 

10 Essential Steps to Prepare for eCTD v4.0 

To ensure your organization is fully prepared, consider the following strategic actions: 

• Map current processes to v4.0 submission architecture 

• Review and update metadata structures 

• Align on custom keywords and naming conventions 

• Conduct a comprehensive gap analysis 

• Validate publishing tools and document workflows 

• Offer team-wide eCTD v4.0 training 

• Perform internal test submissions 

• Partner with your eCTD software vendors 

• Monitor regulatory updates and timelines 

• Join industry working groups and peer forums 

 

Why Early Planning for eCTD 4.0 Matters 

Delaying preparation for eCTD 4.0 can increase compliance risks, lead to submission rejections, and strain internal teams when deadlines arrive. By investing in eCTD v4.0 readiness now, your organization can reduce risks, improve efficiency, and gain a competitive edge in global regulatory submissions.
