2. The International Conference on Harmonization of Technical
Requirements for Registration of Pharmaceuticals for the Human use
(ICH) is a unique project that brings together the regulatory authorities
of Europe, Japan and the United States and experts from the
pharmaceutical industry in the three regions to discuss scientific and
technical aspects of product registration.
3. o European Commission – European Union (EU).
o European Federation of Pharmaceutical Industries and Associations
o Ministry of Health, Labour and Welfare, Japan (MHLW).
o Japan Pharmaceutical Manufactures Association (JPMA).
o US Food and Drug Administration (FDA).
o Pharmaceutical Research and Manufactures of America (PhRMA).
4. To increase international harmonization of technical requirements to
ensure that safe, effective and high quality medicines are developed.
To harmonize technical requirements for registration or marketing
To develop and register pharmaceuticals in the most effective and cost-
To promote public health.
To prevent unnecessary duplication of clinical trails on humans.
To minimize the use of animal testing without compromising safety and
effectiveness of drug.
5. • Four Broad Categories – QSEM.
• Quality (Q): those relating to chemicals and pharmaceutical Quality
Assurance (Stability Testing, Impurity Testing, etc).
• Safety (S): those relating to in vitro and in vivo pre-clinical studies
(Carcinogenicity Testing, Genotoxicity Testing, etc).
6. • Efficacy (E): those relating to clinical studies in the human
subject (Dose Response Studies, Good Clinical Practices, etc).
• Multidisciplinary (M): cross-cutting Topics which do not fit
uniquely into one of the above categories (MedDRA, ESTRI,
M3, CTD, M5).
7. 1. The ICH Steering Committee is responsible for the governance of ICH.
This includes deciding on the adoption of every ICH project, whether a
new topic, maintenance of an existing Guideline, or a specific
2. Each harmonization activity is initiated by a Concept Paper which is a
short summary of the proposal. Depending on the category of
harmonization activity a Business Plan may also be required.
3. Any ICH Party or Observer is welcomed to submit a proposal for a new
4. The ICH Steering Committee decides on the adoption of every ICH
project and then endorses the creation of an EWG/IWG.

Q7: Good Manufacturing Practices
- In February 1998, the ICH Steering Committee agreed that GMP for Active
Pharmaceutical Ingredients (APIs) should be adopted as an ICH topic.
Q8: Pharmaceutical Development
- This annex describes the principles of quality by design (QbD). The annex is not intended
to establish new standards, however, it shows how concepts and tools (e.g., design space)
outlined in the parent Q8 document could be put into practice by the applicant for all dosage
20. Q9: Quality Risk Management
- This Guideline provides principles and examples of tools of quality risk management that
can be applied to all aspects of pharmaceutical quality including development,
manufacturing, distribution, and the inspection and submission/review processes
throughout the lifecycle of drug substances and drug (medical) products, biological and
biotechnological products, including the use of raw materials, solvents, excipients,
packaging and labelling materials.
Q10:Pharmaceutical Quality System
- This Guidelines applies to pharmaceutical drug substances and drug products, including
biotechnology and biological products, throughout the product life cycle.
21. Q11: Development and Manufacture of Drug Substances
- This new guidance is proposed for Active Pharmaceutical Ingredients (APIs) harmonising
the scientific and technical principles relating to the description and justification of the
development and manufacturing process (CTD sections S 2.2. – 2.6) of Drug Substances
including both chemical entities and biotechnological/biological entities.
Q12: Lifecycle Management
- This new guidelines is proposed to provide guidance on a framework to facilitate the
management of post-approval Chemistry, Manufacturing and Controls (CMC) changes in a
more predictable and efficient manner across the product lifecycle. Adoption of this new
ICH Guidelines will promote innovation and continual improvement, and strengthen quality
assurance and reliable supply of product, including proactive planning of supply chain
22. ICH GUIDELINES FOR STABILITY TESTING
• Q1A(R2): Stability Testing of New Drug Substances and Products.
• Q1B: Stability Testing: Photostability Testing of New Drug Substances and Products.
• Q1C: Stability Testing for New Dosage Forms.
• Q1D: Bracketing and Matrixing Designs for stability testing of New Drug Substances and Products.
• Q1E: Evaluation of Stability Data.
• Q1F: Stability Data Package for Registration application in Climatic Zones III & IV.
• Q5C – Stability testing of biotechnological/biological products.
23. OBJECTIVE OF THE GUIDELINES:
- It defines stability of drug substances and drug product for registration of
application of NCE or associated drug, within three regions of ICH i.e., EU,
NOTE: It does not cover testing for registration of drug substances or products
intended for import or export to other areas of the world.
24. - Light can affect drugs, causing chemical changes so…
1. To Evaluate that light exposure does not result in unacceptable
2. Provides means of screening drug early in the development
process & allows identification of particular photo labile drug.
3. Gives idea about how to store drug.
4. For generation of photostability information for submission in
Registration Applications for new molecular entities and associated
- A new dosage form is defined as a medicinal product which is a different
pharmaceutical product type, but containing the same active substances as included in
an existing product approved by the pertinent regulatory authority.
- Products of a different route of administration (e.g., oral to parenteral), new specific
functionally/delivery systems (e.g., immediate release tablet to modified release tablet)
and different dosage forms of the same route of administration (e.g., capsule to tablet,
solution to suspension).
1. Stability protocols for the new dosage forms should follow the guidance in the parent
stability guideline in principle. However, a reduced stability database at submission time
be acceptable with proper justification.
2. E.g., 6 months accelerated and 6 months long term data from ongoing studies may be
acceptable in certain justified cases.
26. • Outlines recommendations, principles, and considerations for reduced
• Full Study Design: Samples for every combination of all design factors
are tested at all time points.
• Reduced Study Design: Not all samples for every factor combination
are tested at all time points. Ex: bracketing, matrixing.
27. It describes:
• How to propose a retest period for drug substances and a shelf life
for drug products in the registration application.
• When and how a extrapolation beyond available data can be
• EXTRAPOLATION: Extrapolation is the practice of using a known
data set to infer the information about a future data.
28. Climatic conditions in the countries where the product is to be marketed
should be carefully considered during the development phase. So the
world has been divided into four climatic zones based on the prevalent
annual climatic conditions.
Temperature and humidity determine the storage conditions and so they
greatly affect the stability of the product.
29. ICH Quality guidelines serves as important tool for the quality
of the products across the globe.
