Frequently Asked Questions

What is eCTD v4.0?
eCTD v4.0 (Electronic Common Technical Document version 4.0) is the latest international standard for electronic Regulatory submissions developed by International Council for Harmonisation (ICH) of Technical Requirements for Pharmaceuticals for Human Use. eCTD v4.0 enables improved workflows, enhanced lifecycle management, flexible metadata, and two-way communication between sponsors and Regulatory authorities.
Is eCTD v4.0 mandatory in Japan?
Presently, eCTD v4.0 is not mandatory in Japan. The Pharmaceuticals and Medical Devices Agency (PMDA) is conducting pilot submissions and finalising guidance, with full adoption mandated from April, 2026. Early preparation is recommended to ensure compliance.
What are the key differences between eCTD v3.2.2 and v4.0?
Features eCTD v3.2.2 eCTD v4.0
Metadata Fixed and limited Flexible and reusable
Communication One-way submissions Supports two-way communication
File Structure Submission-based Content-centric, reusable files
Lifecycle Management Redundant documents Streamlined with document reuse
Technical Standard ICH-based HL7 RPS-based
What is Japan’s PMDA timeline for eCTD v4.0 implementation?
  • 2022 Onwards: Pilot testing by PMDA
  • 2025–2026: Voluntary submissions encouraged
  • April 2026: Mandatory adoption

Why is Japan adopting eCTD v4.0?
eCTD v4.0 offers advantages such as improved efficiency, increased usability, enhanced compliance, forward compatibility and controlled vocabularies and it is important to note that Japan is taking a lead and is one of the first regions to mandate eCTD v4.0. Japan aims to harmonize with global regulatory standards (ICH M8), improve submission efficiency, reduce redundancy, and enhance interoperability with agencies such as USFDA and EMA.
Which are the Health Authorities across the globe who already accept eCTD v4.0 submissions?

US FDA:

The FDA has been actively involved in the transition to eCTD v4.0, with a pilot and voluntary submissions since 2024, followed by mandatory implementation in 2029.

European Medicines Agency (EMA): The EMA is transitioning to eCTD v4.0 for both centrally authorized products (CAPs) and nationally authorized products (NAPs). Pilot submissions for CAP is encourages from 2025 onwards.

Health Canada:

Health Canada also participated in a technical pilot in 2023, with voluntary implementation expected to start in 2026 and mandatory implementation in 2028.

Japan's PMDA:

Japan's MHLW/PMDA completed a technical pilot in Q2 2021, with voluntary implementation in 2022 and a mandatory implementation in 2026.

The transition to eCTD v4.0 is a global effort to streamline regulatory submissions and improve communication between regulatory agencies and pharmaceutical companies. The International Council for Harmonisation (ICH) is a key organization driving this harmonization. 

Which PMDA drug submission categories are impacted by eCTD v4.0?
  • New Drug Applications (NDAs, BLAs, ANDA)
  • New Master Files (DMFs)
  • Subsequent submissions
  • Post-marketing changes
  • Renewals and re-examinations
Are new tools required for eCTD v4.0 compliance?
Yes. Companies will need HL7 Regulated Product Submission (RPS)-compliant publishing software, metadata management tools, lifecycle tracking solutions, and updated document management systems.

Is eCTD v4.0 backward compatible with v3.2.2?
No. eCTD v4.0 uses a different technical framework and is not backward compatible. A migration strategy will be necessary for managing both formats during transition.
Can companies reuse global eCTD v4.0 submissions in Japan?
Partial reuse is possible, but localization is required to meet Japan-specific metadata, language, and structural requirements.
What benefits does eCTD v4.0 bring to Japanese pharma companies?
  • Reduced submission redundancy
  • Enhanced regulatory lifecycle control
  • Streamlined global submissions
  • Improved data quality and compliance
  • Long-term cost savings
What challenges should organizations expect with respect to eCTD v4.0?
  • Technology upgrades and validation
  • Staff training and SOP updates
  • Metadata mapping complexities
  • Managing parallel submissions during transition
