 The Common Technical Document (CTD) is a set of specification
for application dossier for the registration of Medicines and
designed to be used across Europe, Japan and the United States.

 The FDA characterized the CTD as “An information package of
clinical ,non-clinical, manufacturing, technical data in the
same format and with the same content, that would be
submitted for registering new drugs in all three ICH
regions i.e.; US, European Union and Japan’’

 CTD was agreed in November 2000 in San Diego ,USA.

 The CTD is maintained by the International Conference on
Harmonisation of Technical Requirements for Registration of
Pharmaceuticals for Human Use(ICH).

 For industries, it has eliminated the need to reformat the
information for submission to the different ICH regulatory
authorities.

NEED FOR CTD

 Prior to implementation of CTD three major regulatory
authorities EU, USA and Japan has their own set of
guidelines and procedures for the submission of the
regulatory dossiers to get the marketing approval of the
drug.

 Keeping in view all the complication due to different sets
of guidelines for each ICH region, the representatives
from these authorities designed a common set of
guidelines, format and contents for the drug registration in
all the three regions under the same umbrella of ICH.

5

 

MODULES OF CTD

 The CTD is organised into five modules.

Module 1 is region specific and Modules 2, 3, 4 and 5 are intended
to be common for all regions.

 In July 2003, the CTD became the mandatory format for new drug
applications in the EU and Japan, and the strongly recommended
format of choice for NDAs submitted to the FDA, US.

 The Common Technical Document was agreed upon in
November 2000 and re-edited with Numbering and Section
Headers changes, September 2002.

 All modules are harmonised except for the module-1 (Region
specific).

STRUCTURE OF
DOSSIER IN CTD-

FORMAT
7

 

 Module 1 is for administrative
information and prescribing
information, and should contain
documents that are specific to each
region.

 Module 2 contains the CTD
summaries and should begin with a
general introduction to the drug,
including its pharmacological class,
mode of action and proposed
clinical use. Module 2 should also
provide the overall summary of the
‘quality’, the non-clinical overview
and the clinical overview.

 Module 3 contains information on
quality topics

 Module 4 contains the nonclinical
study reports

 Module 5 contains the clinical study
reports.

MODULE:1(Region specific not part of CTD)
Module1 is for administrative information and prescribing

information, and should contain documents that are specific to
each region; for example, application forms or the proposed
label for use in the region.

FOR US FOR EU

• Application form 356h • Application form
• Proposed label

• Summary of product characteristics
• Patent certification / information

• Labelling text and mock-ups
• Debarment certificate (not to be debarred from

• Information about the experts
contracts due to allegations of fraud,

mismanagement, and similar improprieties) • Environmental risk assessment

• Letter of Authorization (LoA)/ DMF letter • Description of the pharmacovigilance
• Labeling text system

• Risk management plan

MODULE-2 (CTD SUMMARY)
 Module-2 contains summaries from QUALITY, EFFICACY & SAFETY

section of CTD.

 Module 2 should also provide the overall summary of the ‘quality’ information
provided, the non-clinical overview and the clinical overview, as well as the

non-clinical written summaries and the tabulated summaries, and the clinical

summary.

 The organisation of summaries in module 2 is described in Guidelines for
M4Q, M4S, M4E:

 M4Q  The CTD Quality

 M4S  The CTD Safety

 M4 E The CTD Efficacy

11

 

GUIDELINES :

 M4Q: QUALITY
 Module-2 Quality overall summary
 Module-3 Quality
 The Quality section of the Common Technical Document

(M4Q) provides a harmonised structure and format for
presenting CMC (Chemistry, Manufacturing and Controls)
information in a registration dossier.

 The table of contents includes sections on Drug Substance
and Drug Product.

 Due to the fact that many CMC topics have not yet been the
subject of ICH guidelines (e.g. drug substance synthesis, drug
product manufacture, container closure), the content of M4Q
is not totally harmonised.

12

 

M4S: SAFETY

 Non-clinical summaries and organisation of Module-4.
 The non-clinical section of the application.
 The CTD Safety (M4S) Guideline delineates the structure and

format of the nonclinical summaries in Module 2 of the
Common Technical Document, and provides the organisation
of Module 4, the Nonclinical Study Reports.

 The Nonclinical Written Summaries (100 – 150 pages) are
recommended to provide more extensive summaries and
discussion of the nonclinical information on pharmacology,
pharmacokinetics and toxicology.

13

 

 M4E: EFFICACY

 Module-2 Clinical overview and Clinical summary
 Module-5 Clinical study reports
 CTD-Efficacy (M4E) describes the structure and format of the clinical

data in an application, including summaries and detailed study
reports.

 There are two high level clinical summaries in Module 2 of the CTD :
 The Clinical Overview, a short document that provides a critical

assessment of the clinical data
 The Clinical Summary, a longer document that focuses on data

summarisation and integration.
 Clinical Study Reports and raw data (where applicable) are included

in Module 5 of the CTD.

14

2.1. Table of contents of Modules 2 – 5
2.2. Introduction.
2.3. Quality overall summary
