CTD and ECTD provide harmonized structures for new drug applications to regulatory agencies in the US, EU, and Japan. The Common Technical Document (CTD) organizes information into five modules covering administrative data, summaries, quality, nonclinical studies, and clinical studies. The Electronic Common Technical Document (eCTD) is the electronic version with XML formatting. It allows for increased transparency, searchability, and review efficiency compared to the paper CTD. Both CTD and eCTD aim to streamline the drug approval process across different regions.

3. INTRODUCTION
 CTD was agreed in November 2000 in San Diego, USA.
 It provides for a harmonized structure and format for new product applications.
 CTD is a set of specification for application dossier for the registration of
medicines and designed to be used across Europe, Japan & US .
 CTD was developed by the European medicines agency(EMEA),Food& Drug
Administration(FDA),the ministry of health, labour & welfare(Japan).

5. NEED OF CTD
All regulatory authority had there own guidelines to submit regulatory dossier to get
marketing approval of the drug.
Thus approval process was slow and time consuming
Thus, the three ICH region ( US, EUROPE & JAPAN) collaborated and developed CTD
format for regulatory submissions

6. C0MM0N TECHNICAL DOCUMENT
 CTD is maintained by the ICH (International Conference
on Harmonization) of technical requirement for
registration of pharmaceuticals for human use.
 The FDA characterized the CTD as “An information
of clinical ,non-clinical, manufacturing, technical data in
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.

 Module 2 – CTD Summaries
 Module 3 – Quality
 Module 4 – Non-Clinical Study Reports
 Module 5 – Clinical Study Reports

15. ELECTRONIC COMMON TECHNICAL
DOCUMENT
 eCTD Its electronic version of CTD so called as CTD, electronic
Common Technical Document (eCTD).
 eCTD composed of two types of specification
 Content specification – As defined by ICH
 Technical specification – Electronic software
CTD TOC (Paper)
eCTD XML Backbone
15

16.  CTD is highly recommended by USFDA for NDAs, BLAs,
DMFs and INDs filing.
 From year 2010 European Union also make compulsory for
electronic CTD submission to all procedures.
CTD eCTD
Module 1 m1

17. eCTD Characteristics Structure
 All Modules 1 to 5 have granularity options.
 PDF documents linked via XML backbone.
 Increased document granularity.
 Transparency of entire submission.
