5. Substantial documentation and data are required in
submissions for import/manufacture and marketing approval of
drugs for human use, resulting in large, complex applications.
Till date, applicants have used many different approaches in
organizing the information and the differences in organization of
data in each application has made reviewing more difficult and
can also lead to omission of critical data or analyses.
Such omissions can result in unnecessary delays in approvals.
Thus, a common format of submission will help in overcoming
these hurdles.

6. WHAT IS CTD?
Application format
The CTD is a set of specifications for a dossier for the
registration of medicines (TGA)
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 for human use in all three ICH regions
(U.S.A., Europe and Japan). 6

7. 7

8.  Prior to the advent of the CTD, regulatory reviewers received
an application from one company and spent a year or more
engaged in its review.
When the review was completed, reviewers received the next
application—most likely in a different format—and had to learn
the structure of the new application.
1996- Industry proposed CTD but ICH regulators were hesitant

disruptive to the review process

Regulators asked industry to do a feasibility study.
That study, conducted in May 1996, evaluated the time it took to
convert an FDA new drug application into an European
Medicines Agency (EMA) submission, and the reverse.
Regulators quickly saw the potential value of harmonizing
submission formats.

CTD
CTD IS A JOINT EFFORT OF 3 REGULATORY AGENCIES:

1.European Medicines Agency (EMEA, Europe),

2. Food and Drug Administration (FDA, USA) and

3. Ministry of Health, Labour and Welfare (MHLW,Japan).
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.
It has been adopted by several other countries including Australia, Canada
and Switzerland (2004).
CTD is maintained by ICH through EWG.

13. In 2000, the 10th Anniversary of ICH, Dr. Caroline Nutley Loew
of the Pharmaceutical Research and Manufacturers of America
(PhRMA) wrote a report, The Value and Benefits of ICH to
Industry, which detailed ICH’s creation, procedures, and
guideline development in the areas of safety, efficacy, and quality.
 Her report anticipated that the CTD would revolutionize the
submission procedures for industry’s regulatory staff.
 Dr. Loew characterized the CTD as “offering potential benefits
to industry far greater than any other single ICH topic,” and
predicted the CTD would afford significant savings in time and
resources as complex multiple submissions were replaced by a
single technical dossier submitted in the three ICH regions—
facilitating simultaneous submission, approval, and launch of new
drugs.
13

14.  In calling the CTD “a topic whose value to industry
cannot be underestimated,”
 Dr. Loew noted that with full incorporation of the CTD and
the electronic CTD (eCTD), ICH could turn its sights to
disseminating guideline information to non- ICH countries,
yielding additional benefits to both regulators and industry.
 Ten years later and in anticipation of ICH’s 20th
Anniversary, the value and benefits of ICH to regulators have
been realized.
14

15. Moreover, implementation of the CTD in 2003 promoted the
involvement of drug regulatory authorities (DRAs) not initially
part of ICH, thereby extending ICH’s harmonized approach.
The development of the Global Cooperation Group, which
includes representatives from five regional harmonization
initiatives and the newly established Regulators Forum, created
to promote participation by non-ICH countries interested in
implementing ICH’s strategies, have also helped incorporate
the CTD into regulatory processes, creating a common
regulatory language that promotes faster access to life-saving
treatments to patients beyond ICH regions.

1995: Concept of CTD proposed by Industry.
November 2000: ICH CTD guideline finalized.
September 2002: Guideline re-edited with Numbering &
Section Header changes.
Prior to July 2003: Voluntary Submission Phase in 3 ICH
Region.
July 1, 2003: Mandatory Requirement in Three ICH Regions.
In India
2009: CDSCO Adopt CTD format for Technical requirements
for registration of biological products.
October 28, 2010: CDSCO give guideline for feedback purpose
for Industry on Preparation of CTD for Import/Manufacture
and Marketing Approval of New Drug for Human Use (i.e.
NDA) & ask for comments and suggestion within 60 days.

20. This guidance is developed by CDSCO based on,
- The ICH Harmonised Tripartite Guideline on “Organisation of
the Common Technical Document for the Registration of
Pharmaceuticals for Human Use”. M4, Step 4 version dated
January 13, 2004, and
- Drugs & Cosmetics Act 1940 and Rules made thereunder.

22. OBJECTIVE OF ICH TO PREPARE THE CTD
The primary objective of the ICH is to avoid duplicative
animal and human testing and to reach a common
understanding of the technical requirements to support the
registration process in the three ICH regions.
These objectives are achieved through harmonized
guidelines and result in a more economical use of human,
animal and material resources, as well as the elimination of
unnecessary delays in the global development and
availability of new medicines, whilst maintaining
safeguards on quality, safety and efficacy, and regulatory
obligations to protect public health.
With the development of the Common Technical Document
(CTD), the ICH hopes to accomplish many of its objectives.
22

23. WHY CTD?
To provide a harmonized common format/template for the
submission of technical requirement to the regulatory
authorities (FDA) that is acceptable in all 3 ICH regions
Reduce the time and resources used to compile applications
It will ease the preparation of electronic submissions.
To facilitate simultaneous submission in three regions.
To facilitate exchange of regulatory information.
 Faster availability of new medicines

70. ADVANTAGES OF CTD
To make the reviewing of each application more easy and
also to avoid omission of critical data or analyses. Omissions
of such data can result in unnecessary delays in approvals.
To save time and resources
To facilitate regulatory review and communications
Appropriate format for the data
Easy to understand and evaluation of data
Applicable to all types of products (NCE,
radiopharmaceuticals, vaccines, herbals, etc.)
70

71. SILENT BENEFITS OF THE CTD
More “reviewable” applications
Complete, well-organized submissions
More predictable format
More consistent reviews
Easier analysis across applications
Easier exchange of information
Facilitates electronic submissions
71

72. LIMITATIONS………
CTD is only a format, its not a single dossier with a single
content.
Legal requirements differ in the different regions
ICH guidelines have not yet harmonized in all requirements
Pharmacopoeias are not harmonized
Applicant may have regional preferences.

73. •The eCTD has proved critical to improving application
submission efficiencies as well as reviewer efficiency.
•Besides delivering submission material to the reviewer in an
expedited manner, the eCTD format has made it easier to
develop standardized reviewer e-templates and review tools for
each of the review disciplines.

IS CTD MANDATORY FOR ALL TYPE OF
SUBMISSIONS?
CTD is mandatory for all.
Import and/or manufacture and marketing approval of new
drugs (New chemical entity, new indication, new dosage
forms, new route of administration etc.), as a finished
pharmaceutical product, for first time submission and for
subsequent applications until 4 years.
 Modified release formulations (even after 4 years of
approval by CDSCO)
 Fixed Dose Combinations under item (a) of Appendix VI
of Schedule Y of Drugs and Cosmetics Rules 1945.

75. CONCLUSION
Whilst the realization of the CTD took many years, there is
now a common format for the submission of Marketing
Authorizations Applications across the three ICH regions -
Europe, Japan and the USA.
This should facilitate pharmaceutical companies to make
simultaneous filings in the ICH regions as it will eliminate the
extensive work previously required to convert, for example, a
US dossier to an EU dossier and vice versa.
