• In the 1980s, the pharmaceutical industry had begun expanding beyond
domestic markets of individual countries, thanks to globalization.
• Legislations regarding quality standards of drugs were becoming more
Complex the world over, and it was becoming difficult for a manufacturer
located in one country to match the specific drug regulatory requirements of
another country to which they wished to export medicines.
• Regulators of one country were focused on their regulations and any products
that didn’t meet their requirements were rejected. Considering the increasingly
international nature of the pharmaceutical market, drug regulators decided to
work in collaboration, and this led to the birth of the International Conference
on Harmonization (ICH).
INTRODUCTION

Prof. Mali Sunayana

The full form of ICH is "International Conference on Harmonization of
Technical Requirements for Registration of Pharmaceuticals for Human Use.
“ This body was set up to bring together representatives of pharmaceutical
industry and regulatory bodies to discuss technical and scientific aspects of
registration of drugs.
As the pharmaceutical industry grew more international, the differences in
technical requirements across countries meant that drug makers had to spend
lot of time and money to duplicate test procedures if they wanted to market
their products at an international level.
It started becoming important to make safe and effective drugs available to
patients all over the world without the delays caused by regulations not
matching across regulatory bodies of the different countries.
ICH AND ITS PURPOSE
4
Prof. Mali Sunayana

Purpose of ICH may be summarized as follows:
• Ensuring quality, safety and efficacy of drugs.
• Harmonization of drug technical requirements.
•Avoid duplication of human clinical trials.
•Reduce use of animal testing but without a compromise on evaluating
efficacy and safety of drugs.

Prof. Mali Sunayana

HISTORY OF ICH
• The European Commission pioneered the harmonization concept of
pharmaceuticals in the 1980s as it moved towards developing a single market.
Observing the success of this discussions began between the United States, Europe
and Japan to explore the possibility of harmonization.
• During the World Health Organization's Conference of Drug Regulatory
Authorities in 1989 in Paris, an action plan was drawn up for this harmonization.
Drug authorities then reached out to the International Federation of
Pharmaceutical Manufacturers and Associations (IFPMA) to decide about an
international, joint industry-regulatory body initiative.
•In April 1990, a meeting was held at Brussels, resulting in the birth of
ICH.
•Representatives of industry associations and regulatory agencies of Europe, US
and Japan met to plan an International Conference.

Prof. Mali Sunayana

• During the first Steering Committee meeting of ICH, the stakeholders reached
an agreement about the terms of reference. They decided that the three criteria on
which approval and authorization for new medicines would be given would be
Quality, Safety and Efficacy.
• It was agreed that harmonization would focus on topics falling under these
three critical criteria .
• Over the years after its inception, ICH has evolved and grown to make greater
harmonization possible to ensure development of effective, safe, high quality
medicines and their easy registration.
• The ICH also developed the concept of Common Technical Document (CTD)
and Medical Dictionary for Regulatory Activities (MedDRA).
• One of the biggest successes of ICH was the introduction of the concept of
Quality by Design (QbD) to the pharmaceutical industry In 2009.
• Organizational changes were made in October 2015 and now, ICH comprises
15 dembers and 32 Observers.

Prof. Mali Sunayana

 PROCESS OF HARMONIZATION:-
The harmonization activities of ICH may fall into one of four categories.:-
Formal ICH Procedure, Q 8L A Procedure, Revision Procedure and
Maintenance Procedure.
 First, a Concept Paper is prepared for the activity to be harmonized.
This is a brief summary of the concept being proposed. Sometimes, a
business plan may also be prepared to highlight the cost: benefit ratio of
the harmonizing activity.
Type of Procedure Deals With
Formal ICH Procedure New Topic for Harmonization
Q&A procedure Clarification for an existing ICH
Guideline
Revision Procedure Adding New Information To an
existing ICH Guidelines
Maintenance Procedure Changes to be made to maintain a
guideline
9
Prof. Mali Sunayana

The formal ICH procedure then begins, in the following steps:
Step 1: Building consensus:
Based on the objectives specified in the Concept Paper, a working group
prepares a consensus draft called the Technical Document. The working group's
technical experts sign off on this, and the Step 1 Experts Technical Document is
submitted to the ICH Assembly with a request for adoption.
Step 2: (a) Based on the report:
Assembly confirms that the scientific consensus exists for the technical issues
and the Technical Document may proceed further for regulatory consultation.
(b) This draft guideline is examined and endorsed by regulatory members of the
ICH Assembly.
10
Prof. Mali Sunayana

Step 3: This happens in three different stages:
Consultation, discussion and finalization of the Expert Draft Guideline by
regulatory members at different levels.
Stage 1: The draft guideline goes to the different ICH regions for discussion in
their respective regulatory regions.
Stage 2: All comments obtained during stage 1 are addressed by the expert
working group and after discussion, consensus is reached to prepare the step 3
Experts Draft Guideline.
Stage 3: This draft guideline is finalized and signed by the ICH regulatory
member experts. The document is sent to ICH Assembly regulatory members for
further proceeding to step 4.
Step 4: ICH Assembly regulatory members agree that sufficient scientific
consensus exists an the draft guideline, and it gets adopted as the ICH
Harmonized Guideline.
Step 5: ICH Harmonized Guideline is implemented in all the ICH regions
through their respective regulatory procedures. Information about when it has
become effective is sent to the ICH Assembly and published on the ICH website.

ICH GUIDELINES: QUALITY,
SAFETY,EFFICACY,
MULTIDISCIPLINARY(QSEM)
12
Prof. Mali Sunayana

(a) Quality guidelines: These guidelines cover the areas of quality of drug
products such as impurity testing and stability studies and a flexible approach to
quality on the basis of GMP risk management.
(b) Safety guidelines: They help to detect potential risks such as genotoxicity.
carcinogenicity and reprotoxicity. For example, the ICH came up with a non-
clinical test methodology to evaluate QT interval prolongation which is probably
the most significant reason why drugs have been withdrawn in recent times.
(c) Efficacy guidelines: These guidelines provide guidance about designing,
conducting. safety aspects and reporting of clinical trials for pharmaceutical
products. Novel drug products derived from biotechnology and genomic/
pharmacogenetic techniques for targeted drug delivery are also covered.
(d) Multidisciplinary guidelines: Topics in the pharmaceutical field that do not
fit into any of the above categories are covered under this area. This guideline
also includes details of (MedDRA), CTD and standards such as Electronic
Standards for the Transfer of Regulatory Information (ESTRI)
14
Prof. Mali Sunayana

ICH GUIDELINES FOR
STABILITY
• Stability testing is the systematic approach
towards drug development process.
• Stability testing is important because drug
products must be stable when administered to
the patients.
• A well designed stability protocol should
contain the following information:-
 No. of batches
 Containers and closures
 Orientation of storage of containers
 Sampling time points
 Test storage conditions
 Test parameters
 Test methodology
 Acceptance criteria
19
Prof. Mali Sunayana

 TYPES OF STABILITY TESTING:-
1. Real Time Testing:-
This involves testing drug product for a longer duration to find out what is the
maximum product degradation when stored as recommended.
2. Accelerated Stability Testing:-
Here, product is subjected to stress in the form of higher temperatures, moisture,
agitation, light, pH, and packaging conditions to study its degradation profile.
3. Retained Sample Stability Testing:-
This Is Testing Of Samples Retained From Each Batch That Has Been Sent Into
The Market.
4. Cyclic Temperature Stress Testing:-
Not routinely used. It involves subjecting the products to temperature stresses
in a way to mimic likely market storage conditions
20
Prof. Mali Sunayana

 STABILITY TESTING PROTOCOL:-
This is the written document that describes all major requirements of a well-
controlled stability study for a given drug substance or drug product. The basic
information to be included In a stability test protocol includes:
 Batch selection how many batches to be tested
 Containers and closures that must be used for the testing
 Different positions in which product containers must be kept during testing
 Frequency of drawing samples for analysis
 Overall sampling plan when and how much to sample and from where
 Test storage conditions based on climatic zone where drug will be used
 Parameters to be tested to evaluate product stability mainly the ones expected to
change after storage
 Methods to be used for testing, and their validation
 Acceptance criteria for result values, and for degradation products
The data obtained by performing the stability studies Is used for expiration dating
of the drug product and to determine its shelf life
21
Prof. Mali Sunayana

 OVERVIEW OF ICH STABILITY GUIDELINES CONTENTS:-
Some of the areas covered by the ICH guidelines on stability testing include:
 Stress Testing:- Study of degradation pathways, effects of change in
temperature, relative humidity, pH changes, susceptibility to be degraded by
moisture (hydrolysis).
 Photostability Testing:- Study of effect of light on drug chemistry.
 Batch Selection For Stability Testing:- Not less than 3 primary batches of drug
substance.
Testing Of Container Closure System:- At least thrice; once in 3 months in first
year,
once in 6 months during the second year and then annually.
 Storage conditions for the drug substance and product.
 Storage instructions with respect to different regions and climatic zones, and
labeling requirements regarding storage region-wise
22
Prof. Mali Sunayana

• Thanks to the harmonization process of ICH, there are now more than 50
harmonized guidelines. This had led to streamlining of the research and
development process and in turn, made it easier to develop and market new
medicines to patients all over the globe.
• There are certainly concerns that non-ICH members are not consulted in the
decision-making: however, the educational material provided by ICH is largely
beneficial for such countries to streamline their own R&D and drug
manufacturing efforts.
• The membership of ICH has grown over the years of its inception. For ICH to
continue to grow and stay relevant, it is necessary to have greater participation
from more countries across the world.
• Future plans must consider the involvement of non-ICH members, recognizing
and funding ways to overcome the challenges that developing nations face in
using the ICH guidelines.
