CTD (Common Technical Document) Structure

Private Confidential 2

CTD ISA common harmonized format for applications for preparing marketing authorizations in ICH regions. It is a TEMPLATE for presenting data in the dossier

CTD IS NOTA statement of data requirements for 

applications.

Page 4: Advantages and Challenges with using CTD Module …...•Module 1 ‐Administrative Information and Prescribing Information. This module should contain documents specific to each region

The Common Technical Document is organized into five modules: 

• Module 1 ‐ Administrative Information and Prescribing Information.

This module should contain documents specific to each region and the content and format of this module can be specified by the relevant regulatory authorities.

• Module 2 ‐ CTD Summaries. 

This Module contain 7 sections:  CTD Table of Contents; CTD Introduction; Quality Overall Summary; Nonclinical Overview; Clinical Overview; Nonclinical Written and Tabulated Summaries; Clinical Summary.

• Module 3 ‐ Quality Information on Quality (M4Q) 

• Module 4 ‐ Nonclinical Study Reports  (M4S)

• Module 5 ‐ Clinical Study Reports (M4E)

Page 5: Advantages and Challenges with using CTD Module …...•Module 1 ‐Administrative Information and Prescribing Information. This module should contain documents specific to each region

• COMMON FORMAT for the preparation of a well‐structured Common Technical Document for applications.

• Authorization holders know WHERE TO PLACE information.

• Board of Health (BoH) reviewers know WHERE TO FIND information.

• Dossiers provide the NECESSARY INFORMATION  for review and approval.

• The common structure for ICH markets FACILITATES REVIEW and MINIMIZES QUERIES.

• Simplification  on the EXCHANGE OF REGULATORY INFORMATION between Regulatory Authorities.

• Potentially decrease TIME TO MARKET of new drugs.

ICH M 4 ‐ Objectives & Advantages

Page 6: Advantages and Challenges with using CTD Module …...•Module 1 ‐Administrative Information and Prescribing Information. This module should contain documents specific to each region

• Template changes

Review of internal procedures for authoring and assembling of dossier according to the structure of the CTD. 

• Convert pre‐existing filed applications into CTD format

• Location issues

Health Authorities have allowed some variability 

• ICH M4 granularity document 

This is really applicable to submitting electronically in CTD format (eCTD), but authoring documents to the right granularity now, rather than having to change it later is beneficial.

• The control strategy is split across sections.

• M4 does not specifically use the terminology of established conditions but its applicability to Module 3 is clear from the draft ICH Q12.

• Standardization of established conditions and definition of lifecycle management options will streamline lifecycle management and remove the biggest areas of divergence.

• Expectation is national control documents will align on established conditions and not include additional parameters or variables not contained within Module 3 when ICH Q12 is finalized…

The CTD represents one of the most successful international harmonization activities undertaken! 

A well managed implementation of CTD led to:

• More efficient work of National Regulatory Authorities 

• Faster access to medicines

• Mutual benefit (industry and regulators)

• Similar content and expectation in CTD also favor regulatory reliance initiatives (e.g. joint pilot reviews by EMA/FDA on QbD submissions)

Final Considerations
