• ICH is comprised of representatives from six parties that
represent the regulatory bodies and research-based industry
in the European Union, Japan and the USA.
• In Japan, the members are the Ministry of Health, Labour and
Welfare (MHLW), and the Japan Pharmaceutical
Manufacturers Association (JPMA).
• In Europe, the members are the European Union (EU), and
the European Federation of Pharmaceutical Industries and
Associations (EFPIA).
• In the USA, the members are the Food and Drug
Administration (FDA), and the Pharmaceutical Research and
Manufacturers of America (PhRMA).

ICH structure
The ICH structure consists of the ICH Steering Committee,
ICH Coordinators, ICH Secretariat and ICH Working
Groups.
ICH Steering Committee
The Steering Committee is the body that governs the ICH,
determines the policies and procedures for ICH, selects
topics for harmonization and monitors the progress of
harmonization initiatives. Each of the six ICH parties has
two seats on the ICH Steering Committee.
ICH Coordinators
The Coordinators are fundamental to the smooth running of
the ICH and are nominated by each of the six parties. An
ICH Coordinator acts as the main contact point with the
ICH Secretariat.
7

ICH Secretariat
The Secretariat is primarily concerned with preparations
for, and documentation of, meetings of the Steering
Committee as well as coordination of preparations for
Working Group and Discussion Group meetings.
Information on ICH Guidelines and the general ICH
process can be obtained from the ICH Secretariat.
ICH Working Group
Depending on the type of harmonization activity needed,
the Steering Committee will endorse the establishment of
one of three types of working group i.e., Expert Working
Group (EWG), Implementation Working Group (IWG) or
Informal Working Group.
8

ICH OPERATION
ICH operates through the ICH Steering Committee with
administrative support from the ICH Secretariat and ICH
Coordinators.
The Steering Committee meets at least twice a year . During these
meetings, new topics will be considered for adoption, reports are
received on the progress of existing topics, and maintenance and
implementation of the guidelines are discussed.
The topics identified for harmonization by the Steering Committee
are
selected from Safety, Quality, Efficacy, and Multidisciplinary
matters.
9

Steps in the ICH process
Step-1: Drafts are prepared and circulated through
many revisions until a "final harmonised draft" is
completed
Step-2: This draft is signed by the EWG as the agreed-upon
draft and forwarded to the Steering Committee
for signing which signifies acceptance for
consultation by each of the six co-sponsors
Step-3: The three regulatory sponsors initiate their
normal consultation process to receive comments.
10

 Step-4 is reached when the Steering Committee
agrees that there is sufficient scientific consensus on
the technical issues. This endorsement is based on
the signatures from the three regulatory parties to
ICH affirming that the Guideline is recommended
for adoption by the regulatory bodies of the three
regions.
 Step-5: The process is complete when the guidelines
are incorporated into national or regional internal
procedures(implementation in the 3 ICH regions.)

(d) provide a separate glossary of terms used in the ICH
clinical safety and efficacy related documents that
pertain to clinical trials
72

 E9: Statistical Principles for Clinical Trials
 This biostatistical guideline describes essential
considerations on the design and analysis of clinical
trials, especially the "confirmatory" (hypothesis-testing)
trials that are the basis for demonstrating effectiveness
73

 E10: Choice of Control Group and Related
Issues in Clinical Trials
• This document addresses the choice of control groups in
clinical trials.
• Control groups in clinical trials can be classified on the
basis of two critical attributes: (1) the type of treatment
used and (2) the method of determining who will be in
the control group.
• The type of control treatment may be any of the
following four: (1) placebo, (2) no treatment, (3) different
dose or regimen of the study treatment, or (4) a different
active treatment.
74

 E11: Clinical Investigation of Medicinal
Products in the Pediatric Population
• This document addresses the conduct of clinical
trials of medicines in pediatric populations.
• This document will facilitate the development of
safe and effective use of medicinal product in
pediatrics.
• Specific clinical study include:
• (1) timing of initiation of pediatric studies during
medicinal product development;
• (2) types of studies (pharmacokinetic,
pharmacokinetic/ pharmacodynamic (PK/PD),
efficacy, safety);
• (3) age categories;
• (4) ethics of pediatric clinical investigation.
75

 E12-Guidelines for Clinical Evaluation by
Therapeutic Category
 The ICH Efficacy Guidelines are applicable to all
therapeutic classes of drugs, but there are some
therapeutic classes which need individual drug
evaluation guidelines among the three regions.
76

 E12: Principles for Clinical Evaluation of New
Antihypertensive Drugs
 This document provides general principles for
the clinical evaluation of new anti-hypertensive
drugs.
 It describes core principles for the evaluation of
antihypertensives that are accepted in the three
ICH regions, but some region-specific
differences remain, therefore this document
should be considered an "ICH Principle
Document" rather than an "ICH Guideline".
77

 E14: The Clinical Evaluation of QT/QTc Interval
Prolongation and Pro-Arrhythmic Potential for
Non-Antiarrhythmic Drugs
• This document provides recommendations to sponsors
concerning the design, conduct, analysis, and
interpretation of clinical studies to assess the potential of
a drug to delay cardiac repolarization.
• This assessment should include testing the effects of new
agents on the QT/QTc interval as well as the collection of
cardiovascular adverse events.
• The investigational approach used for a particular drug
should be individualized, depending on the
pharmacodynamic, pharmacokinetic, and safety
characteristics of the product, as well as on its proposed
clinical use.
78

 E15: Definitions for Genomic Biomarkers,
Pharmacogenomics, Pharmacogenetics, Genomic
Data and Sample Coding Categories
• In order to develop harmonised approaches to drug
regulation, it is important to ensure that consistent
definitions of terminology are being applied across all
constituents of the International Conference on
Harmonisation (ICH).
• An agreement on definitions will facilitate the
harmonization in the discipline of pharmacogenomics
and pharmacogenetics for global drug development and
approval processes.
79

 E16: Genomic Biomarkers Related to Drug
Response: Context, Structure and Format of
Qualification Submissions
 The guideline describes recommendations regarding
context, structure, and format of regulatory submissions
for qualification of genomic biomarkers(E15).
 clinical and non-clinical genomic biomarkers related to
drug response including pharmacokinetics,
pharmacodynamics,efficacy and safety aspects.
80

• Multidisciplinary Guidelines
"Multidisciplinary" Topics, i.e., Topics which
do not fit uniquely into one of the above
categories (MedDRA, ESTRI, M3, CTD, M5)
81

M1 Medical Terminology
• New Medical Dictionary for Regulatory Activities
Terminology (MedDRA) was developed by the working
group of ICH and is owned by the International
Federation of Pharmaceutical Manufacturers and
Associations (IFPMA) acting as trustee for the ICH
steering committee.
• It provides an international medical dictionary
applicable to all phases of product development.
• Its goal is to provide a comprehensive and specific
terminology to help standardize, facilitate and simplify
regulatory processes.
82

 M2 Electronic Standards for Transmission of
Regulatory Information (ESTRI)
 Facilitate international electronic communication by
evaluating and recommending the specifications
 The first Specification developed by the M2 EWG was the
Individual Case Safety Report (ICSR), created as the
electronic message for the ICH E2B(R2)
 The second Specification developed by the M2 EWG was
the Electronic Common Technical Document (eCTD)
created as the electronic message for the Common
Technical Document developed by the ICH M4.
 ICH M2 has initiated the development of the Next Major
Version of the eCTD (eCTD NMV) to improve robustness,
flexibility and long term stability of the message.
83

• M3(R2): Guidance on Non-Clinical Safety Studies
for the Conduct of Human Clinical Trials and
Marketing Authorization for Pharmaceuticals
• The present guidance represents the consensus that
exists regarding the type and duration of nonclinical
safety studies and their timing to support the conduct of
human clinical trials and marketing authorization for
pharmaceuticals.
• The nonclinical safety assessment for marketing
approval of a pharmaceutical usually includes
pharmacology studies, general toxicity studies,
toxicokinetic and nonclinical pharmacokinetic studies,
reproduction toxicity studies, genotoxicity studies and,
for drugs that have special cause for concern or are
intended for a long duration of use
84

 The goals of the nonclinical safety evaluation generally
include a characterisation of toxic effects with respect
to target organs, dose dependence, relationship to
exposure, and, when appropriate,potential
reversibility.
 This information is used to estimate an initial safe
starting dose and dose range for the human trials and
to identify parameters for clinical monitoring for
potential adverse effects.
85

 M4:The Common Technical Document
• The Common Technical Document provides a
harmonised structure and format for new product
applications. The Common Technical Document was
agreed upon in November 2000 in San Diego, USA.
• This Common Technical Document is divided into four
separate sections. The four sections address the
application organisation (M4 organise), the Quality
section (M4Q), the Safety section (M4S) and the
Efficacy section (M4E) of the harmonised application.
• An electronic version of the Common Technical
Document (eCTD) developed by the eCTD
Implementation Working Group. The Electronic
Common Technical Document (eCTD) allows for the
electronic submission of the Common Technical
Document (CTD) by an applicant to regulator
86

 M5: Data Elements and Standards for Drug
Dictionaries
• This document provides guidance on the harmonized
standards related to core sets of medicinal product
information and medicinal product terminology.
• Facilitate the exchange and practical use of medicinal
product data by regulators and pharmaceutical
industry.
