eCTD - electronic Common Technical Document  

CambReg has over 4 years experience of eCTD publishing using the fully functional DocuBridge software.

What does it really mean?

The eCTD is an electronic industry to agency interface:

  • The eCTD facilitates Health Authority review of your product dossier meaning a shorter time to market.
  • The eCTD stores all approved data in one place.
  • The eCTD is an aid to regulatory compliance, being a living document it reflects the changes made to your product through a series of ‘sequences’
  • eCTD applications attract a lower fee

Why is it needed?

Pharmaceutical companies have been manually handling huge amounts of paper based documentation for regulatory submissions for decades with multiple copies of these bulky documents being sent to regulatory authorities for review.  Handling and archiving of these dossiers leads to problems. The paper process is cumbersome and involves significant investment of time, money and effort.  The problem is compounded when reviews and modifications occur throughout the product’s lifecycle.  Both industry and regulators recognised the standardising the process and automating submissions was the way forward.  The eCTD is the proposed solution to these issues.

The eCTD was developed by the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) and is an international standard for document submission that is currently recognised by regulatory agencies across the EU, USA and Japan.  Organisations have begun moving towards eCTD implementation even though it is not yet compulsory world wide. 

There is no difference between CTD and eCTD in terms of scientific, technical and clinical content. However, there are regional differences in the eCTD implementation between ICH regions. At CambReg we keep up to date with regional changes, so you can be sure your electronic submission will be in line with current local requirements.
