2. • The CTD is a set of specifications for a dossier for the registration of
medicines . CTD is an internationally agreed “well structured common
format” for the organization of the technical requirements that is to be
submitted to the regulatory authority as an application for the
registration of pharmaceuticals . Its electronic version is called eCTD.
• eCTD (electronic Common Technical Document) is a standard format
of submitting Regulatory information (such as applications,
supplements, and reports) to the concerned Health Authorities (HAs).
• This guideline provides recommendations to applicants on electronic
submissions with the electronic Common Technical Document for the
Registration of Medicines.
INTRODUCTION

3. In 2003 ectd was implemented in all ICH regions.
The major version (v4.0) was added by ICH M8 EWG in 2015.

5. OBJECTIVE
1. Establishing a worldwide standard for electronic submissions.
eCTD has been turned into the standard norm for industry-wide
submissions around the world.​
2. It give more accountability and ease decision making .​
3. The purpose of introducing eCTD was to reduce the burden on
the reviewers of the HAs.
4. It also simplifies the process of submission as all the Regulatory
authorities use it as a standard format.

6. FORMATE OF eCTD
• Module1 – administration information (specific region)​
• Module 2 – summaries.
• Module3 – Quality.
• Module4 - non clinical study report .​
• Module5 - clinical study report.

7. Structure format for eCTD
Not part of eCTD
These are part of
eCTD

8. STRUCTURE FORMATE FOLDER
• e-Identifier Number:Every application is
given a unique number by the Agency which
becomes the top-level folder.
• eCTD Sequence Number: Every submission
is given a sequential 4 digit number. The
initial filing submitted in eCTD format is
usually 0000.
• Module 1 National/Regional administrative
data.
• Modules 2 to 5 follow ICH CTD granularity

13. META DATA
• Metadata is data about data.
• Structural metadata is used in eCTD to organize information by
specific criteria; identification of data, grouping and dividing data, and
the location of information.

14. Leaf titles
Leaf titles including meaningful
information in leaf titles makes
submissions easier to navigate and
facilitates the evaluator’s task.
The leaf titles should be short,
meaningful and indicative of the
document’s content, so that
someone who isn’t familiar with the
application would know what the
document is from the leaf title
without having to open the
document.

15. Module 1
1. This module contains administrative information that is unique
for each region.
2. Regional guidance will provide the specific instructions on how to
provide the administrative forms and detailed
prescribing information.
3. It is not a part of eCTD. Because it is specific for particular region.
4. Authorities have additional documentation requirements (eg. batch
analysis , method validation reports).

19. Granularity
An enhanced granularity is required in this module and to make easy to
review/readable. The granularity should be built with Node Extensions(
additional folder of granular) and Subfolders including numbering of the
subfolders. Further information can be found in these folder.

4) MD5 CHECK SUM
A checksum is unique identifier used to verify the integrity of file by
comparing two set of data to make sure they are same .A checksum (MD5)
should be included for each file in the eCTD, allowing the recipient to verify
the integrity of physical files in the submission. It is generated by applicant to
check integrity of file.
5)VIRUS CHECK
The applicant is responsible for checking the virus in submission unit.

26. Validation is process that ensure the eCTD dossier is technically correct after

28. LIFE CYCLE MANAGEMENT (LCM)
An eCTD application is an evolving entity that grow with each
submission (sequence).
1. Life cycle management at the submission layer (i.e. eCTD-sequence)
2. Life cycle management at the document layer (eCTD leaf)
3. Life cycle management of specific documents.
4. Responses to Authority Recommendations.
5. Tabulated Schedule of Amendment.

29. BASELINE SUBMISSIONS
A baseline submission marks the change from a paper based
submission, or an e-submission, to an eCTD submission
The paper copies and the hard media should be submitted jointly. The
eCTD on DVD/CD/USB should be submitted at specified address of RA.
