Guidance for Industry1

M4Q: The CTD — Quality

INTRODUCTION

This is one in a series of guidances that provide recommendations for applicants preparing the

Common Technical Document for the Registration of Pharmaceuticals for Human Use (CTD) for

submission to the U.S. Food and Drug Administration (FDA). This guidance presents the agreed

upon common format for the preparation of a well-structured Quality section of the CTD for

applications that will be submitted to regulatory authorities. A common format for the technical

documentation will significantly reduce the time and resources used to compile applications for

registration of human pharmaceuticals and will ease the preparation of electronic submissions.

Regulatory reviews and communication with the applicant will be facilitated by a standard

document of common elements. In addition, exchange of regulatory information among

regulatory authorities will be simplified.

For information on the Safety and Efficacy sections of the CTD, see the individual guidances for

industry that discuss those parts of the CTD. For general information about the CTD, as well as

specific information about Module 1 (regional administrative information), see the guidance for

industry, General Considerations for Submitting Marketing Applications According to the

ICH/CTD Format. 2

 The CTD guidances are intended to be used together with other ICH and

Agency guidances. Please refer to those guidances for detailed information about the contents of

an application.

 

1

This guidance was developed within the Expert Working Group on Quality of the International Conference on

Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) and has been

subject to consultation by the regulatory parties, in accordance with the ICH process. This document was endorsed

by the ICH Steering Committee at Step 4 of the ICH process, November 2000. At Step 4 of the process, the final

draft is recommended for adoption to the regulatory bodies of the European Union, Japan, and the United States.

2

 A draft version of the General Considerations guidance is currently available. Once it has been finalized, it will

represent the Agency's thinking on this topic.

This guidance represents the Food and Drug Administration's (FDA's) current thinking on this topic. It

does not create or confer any rights for or on any person and does not operate to bind FDA or the

public. An alternative approach may be used if such approach satisfies the requirements of the

applicable statutes and regulations.
2

BACKGROUND

The CTD

Through the ICH process, considerable harmonization has been achieved among the three

regions (Japan, Europe, and the United States) in the technical requirements for the registration

of pharmaceuticals for human use. However, until now, there has been no harmonization of the

organization of a submission. Each region has its own requirements for the organization of the

technical reports in the submission and for the preparation of the summaries and tables. In

Japan, the applicants must prepare the GAIYO, which organizes and presents a summary of the

technical information. In Europe, expert reports and tabulated summaries are required, and

written summaries are recommended. The U.S. FDA has guidance regarding the format and

content of the new drug application submission. To avoid generating and compiling different

registration dossiers, this guidance describes a format for the Quality section of the CTD that will

be acceptable in all three regions.

Preparing and Organizing the CTD

This guidance primarily addresses the organization of the information to be presented in the

Quality section of an application for new pharmaceuticals (including biotechnology-derived

products). Guidances also are available that discuss the Safety and Efficacy sections of the CTD.

These guidances are not intended to indicate what studies are required. The guidances merely

indicate an appropriate format for the data that have been acquired. Applicants should not

modify the overall organization of the CTD. However, in the Nonclinical and Clinical

Summaries sections of the CTD, applicants can modify individual formats to provide the best

possible presentation of the technical information to facilitate the understanding and evaluation

of the results.

Throughout the CTD, the display of information should be unambiguous and transparent, to

facilitate the review of the basic data and to help a reviewer become quickly oriented to the

application contents. Text and tables should be prepared using margins that allow the document

to be printed on both A4 paper (E.U. and Japan) and 8.5 x 11” paper (U.S.). The left-hand

margin should be sufficiently large that information is not obscured through binding. Font sizes

for text and tables should be of a style and size that are large enough to be easily legible, even

after photocopying. Times New Roman, 12-point font is recommended for narrative text.

Acronyms and abbreviations should be defined the first time they are used in each module.

References should be cited in accordance with the current edition of the Uniform Requirements

for Manuscripts Submitted to Biomedical Journals, International Committee of Medical Journal

Editors (ICMJE).3

The CTD should be organized into five modules. Module 1 is region specific. Modules 2, 3, 4,

and 5 are intended to be common for all regions. Conformance with the CTD guidances should

by the Vancouver Group and was published in 1979.

help ensure that these four modules are provided in a format acceptable to the regulatory

authorities (see the figure and overall outline on the following pages).

Module 1. Administrative Information and Prescribing Information

This module should contain documents specific to each region; for example, application

forms or the proposed label for use in the region. The content and format of this module

can be specified by the relevant regulatory authorities. For information about this module

see the guidance for industry, General Considerations for Submitting Marketing

Applications According to the ICH/CTD Format.

Module 2. Common Technical Document Summaries

Module 2 should begin with a general introduction to the pharmaceutical, including its

pharmacologic class, mode of action, and proposed clinical use. In general, the

introduction should not exceed one page.

Module 2 should contain 7 sections in the following order:

• CTD Table of Contents

• CTD Introduction

• Quality Overall Summary

• Nonclinical Overview

• Clinical Overview

• Nonclinical Written and Tabulated Summaries

• Clinical Summary.

The individual organization of the Module 2 summaries is described in three separate

documents:

• M4Q: The CTD — Quality

• M4S: The CTD — Safety

• M4E: The CTD — Efficacy.

Module 3. Quality

Information on Quality should be presented in the structured format described in the

guidance M4Q.

Module 4. Nonclinical Study Reports

The Nonclinical Study Reports should be presented in the order described in the guidance

M4S.

Module 5. Clinical Study Reports

The human study reports and related information should be presented in the order

described in the guidance M4E .

Organization and Format of the ICH Guidances for Industry

Although the CTD is organized by modules, the guidances for industry that provide

recommendations for applicants on preparing the CTD have been organized by topic: Quality,

Safety, and Efficacy. As a result, guidance discussing Module 2 is divided among three

guidances.

• Guidance on the Quality section of the CTD (Module 2, Quality Overall Summary

(QOS), and Module 3) can be found in the guidance for industry M4Q: The CTD —

Quality.

• Guidance on the Safety section of the CTD (Module 2, the Nonclinical Overview and the

Nonclinical Written and Tabulated Summaries, and Module 4) can be found in the

guidance for industry M4S: The CTD — Safety

• Guidance on the Efficacy section of the CTD (Module 2, the Clinical Overview and the

Clinical Summary, and Module 5) can be found in the guidance for industry M4E: The

CTD — Efficacy.

Numbering

In the guidances for industry on the Quality, Safety, and Efficacy sections of the CTD, Arabic

numbers have been assigned to designate those specific sections that should be included in the

CTD. The Arabic numbers used in the guidances also should be used when assembling the CTD

for submission. For specific information on numbering the pages and volumes of the

submission, see the guidance for industry, General Considerations for Submitting Marketing

Applications According to the ICH/CTD Format. Sections in the guidance documents that are

not numbered provide guidance on how to prepare those sections. In this guidance for industry,

sections that should be included in Module 2 and Module 3 of the CTD have been numbered

using the Arabic numbers 2 and 3, respectively.

It is possible that information for more than one drug substance or drug product will be

submitted. In such cases, please continue the use of Arabic numbers by repeating the specific

section’s numbering, making it clear that the data are for an additional drug substance or drug

product. For example, for an additional drug substance (2.3.S), repeat section 2.3.S and include

the name of the additional substance (e.g., 2.3.S [name of drug substance]. The same approach

should be used for an additional drug product (e.g., 2.3.P [name of drug product] and, in the

Efficacy section of the CTD application, for an additional indication (e.g., 2.7.3 pneumonia,

2.7.3 URI).
7

MODULE 2 QUALITY OVERALL SUMMARY

The Quality Overall Summary (QOS) is a summary that follows the scope and the outline of the

Body of Data in Module 3. The QOS should not include information, data, or justification that

was not already included in Module 3 or in other parts of the CTD.

The QOS should include sufficient information from each section to provide the Quality

reviewer with an overview of Module 3. The QOS should also emphasize critical key

parameters of the product and provide, for instance, justification in cases where guidance was not

followed. The QOS should include a discussion of key issues that integrates information from

sections in the Quality module and supporting information from other modules (e.g.,

qualification of impurities by toxicological studies discussed under the M4S module), including

cross-referencing to volume and page number in other modules.

This QOS normally should not exceed 40 pages of text, excluding tables and figures. For

biotech products and products manufactured using more complex processes, the document could

be longer, but normally should not exceed 80 pages of text (excluding tables and figures).

Most of the information requested in the QOS, including tables, figures, or other items and

whether specified in the following text or not, can be imported directly from Module 3.

excipients and control of the production process, as appropriate for the material, process and

agent.

Reference ICH guidances Q5A, Q5D, and Q6B.

For viral adventitious agents:

Detailed information from viral safety evaluation studies should be provided in this section.

Viral evaluation studies should demonstrate that the materials used in production are considered

safe, and that the approaches used to test, evaluate, and eliminate the potential risks during

manufacturing are suitable. The applicant should refer to Q5A, Q5D, and Q6B for further

guidance.

Information essential to evaluate the virological safety of materials of animal or human origin

(e.g. biological fluids, tissue, organ, cell lines) should be provided. (See related information in

3.2.S.2.3, and 3.2.P.4.5). For cell lines, information on the selection, testing, and safety

assessment for potential viral contamination of the cells and viral qualification of cell banks

should also be provided. (See related information in 3.2.S.2.3).

The selection of virological tests that are conducted during manufacturing (e.g., cell substrate,

unprocessed bulk, or postviral clearance testing) should be justified. The type of test, sensitivity

and specificity of the test, if applicable, and frequency of testing should be included. Test results

to confirm, at an appropriate stage of manufacture, that the product is free from viral

contamination should be provided. (See related information in 3.2.S.2.4 and 3.2.P.3.4). In

accordance with Q5A and Q6B, results for viral testing of unprocessed bulk should be included.

In accordance with Q5A, the rationale and action plan for assessing viral clearance and the

results and evaluation of the viral clearance studies should be provided. Data can include those

that demonstrate the validity of the scaled-down model compared to the commercial scale

process, the adequacy of viral inactivation or removal procedures for manufacturing equipment

and materials, and manufacturing steps that are capable of removing or inactivating viruses. (See

related information in 3.2.S.2.5 and 3.2.P.3.5).
