eCTD: structure, lifecycle, and controlled vocabularies
A practical overview of how eCTD 4.0 submissions are structured, how lifecycle works, and where controlled vocabularies show up in real dossiers.
What eCTD 4.0 changes
eCTD 4.0 moves the regulatory submission standard from document-centric to data-centric. Submissions must carry structured metadata that is validated against authority-controlled code lists — not just formatted text in a defined file structure.
- Stricter metadata requirements — controlled vocabulary codes must match authority-published lists exactly.
- Validation at submission time — rejected submissions are increasingly common where CV codes are stale or mismatched.
- Multiple authority implementations — EMA, FDA, Swissmedic and others each manage their own code lists on different release cycles.
View eCTD controlled vocabularies
This section of the site provides you with a lookup tool for exploring eCTD controlled vocabularies across different health authorities. This is based on the eCTD CV data we have ingested from public sources, and is updated periodically as new versions of the code lists are released by the authorities.
Choose an Agency and code list type to explore terms published by that authority.

Explore in the secure portal
Harmonising the controlled vocabualries in your "Regulatory Information Management" systems and your eCTD 4 publication systems in line with the controlled vocabulary requirements of the authorities is a critical part of eCTD 4.0 readiness. The public lookup tool above is a starting point, but the secure portal provides deeper access to HA CV data, cross-agency comparisons, and AI-assisted term mapping between HA code lists and internal Reg App vocabularies. Access to the secure portal is not yet enabled. Access process will be published soon.
Key authorities publishing eCTD CVs
- EMA — SPOR / NCA code lists
- FDA — SPL controlled terminology
- Swissmedic — eCTD 4.0 local lists
- Health Canada — structured submission terms
- PMDA — Japanese regulatory CVs
Each authority publishes on a different release cycle, creating an ongoing alignment burden for pharma regulatory teams.
