# eCTD Publishing

Electronic submissions done right

Based on the content of the Common Technical Document format, the Electronic Common Technical Document transfers regulatory information from industry to agency in electronic form.

## The electronic Common Technical Document (eCTD)

Based on the content of the Common Technical Document (CTD) format, the Electronic Common Technical Document (eCTD) **transfers regulatory information from industry to agency in electronic form**. The technical components consist of a high level folder structure, XML based metadata, document type definitions (DTDs) and stylesheets.

**All types of regulatory information can be submitted in electronic format**, including new applications, variations and renewals for national, mutual recognition, decentralised and centralised procedures.

## How to create eCTDs

The files in an eCTD should be organized according to the version 3.2 of the ICH eCTD specifications and the current version of the EU Module 1 specifications. The eCTD consists of (mostly) **PDF leaf documents**, stored in the **eCTD directory structure**, crucially accessed through the **XML backbone** (index.xml) and with the files integrity guaranteed by the MD5 Checksum.

In order to use eCTD, marketing authorization holders need to invest in **appropriate software** and maintain support systems.
