1. INTERNATIONAL CONFERENCE FOR HORMONIZATION
INTEGRAL UNIVERSITY, LUCKNOW
INTERNATIONAL CONFERENCE FOR HORMONIZATION
(ICH) GUIDELINES & QSEM
PRESENTED BY
Mr. ABDURRAHMAN

2. PURPOSE/INTENT
 To harmonize i.e. to equalize the technical requirements for pharmaceuticals
for human use.
 The allopathic doctor there is engaged in the development of drugs. Drugs at
the market developed and in the meantime such an incident has happened
that shock the whole of West Germany, Europe. It was Thalidomide, a
anticancerous drug . That accident popularly called Thalidomide tragedy.
 Shortly after the drug was sold in Germany, between 5000 and
 Shortly after the drug was sold in Germany, between 5000 and
7000 infants were born with Phocomelia (malformation of the limbs).
 So they decide to make a guideline that all the companies will have bring it
under the ambit of a guideline that all the manufacturing companies should
follow this guideline and according to the same guideline make the product
basically this guideline.
- Safety
- Efficacy
- Quality

3. OBJECTIVES
 Harmonization of legislative & technical requirements
 Mutual acceptance of data between Europe, Japan & US
 To reduce cost of research work duplications
 To reduce time-frame for global marketing of newer drugs after approval
 To maintain & formulate guidelines on quality, safety & efficacy-based
regulations, for consumer & patient benefits

4. LOCATION
 The ICH Secretariat is based in Geneva Switzerland.
 Biennial meetings & conferences of ICH Steering Committee
shuffle between the European Union, Japan & the US.

6. STEPS IN THE ICH PROCESS
 ICH operates through the Steering Committee, with administrative support
from Secretariat & Coordinators .
 Steering committee meets at least twice a year.
 Topics identified for harmonization by Steering Committee selected
from Safety, Efficacy, Quality & Multidisciplinary matters.
 There are 5 steps involved
STEP 1: Drafts are prepared and circulated through many revisions until a "final
harmonized 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.

7. STEPS IN THE ICH PROCESS
STEP 4: This step 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
STEP 5: The process is complete when the guidelines are incorporated into
national or regional internal procedures (implementation in the 3 ICH
regions.)

8. QSEM

temperature, humidity and trial duration for Climatic Zone I and II. Furthermore, the revised
document takes into account the requirements for stability testing in Climatic Zones III and IV
in order to minimise the different storage conditions for submission of a global dossier.

registration applications for new molecular entities and associated drug products. The
guideline provides recommendations on establishing shelf lives for drug substances and drug
products intended for storage at or below “room temperature”.
Q1F - Stability Data Package for Registration Applications in Climatic Zones III and IV
 Describes harmonized global stability testing requirements in order to facilitate access to
medicines by reducing the number of different storage conditions. WHO conducted a survey
amongst their member states to find consensus on 30°C/65% RH as the long term storage
conditions for hot-dry and hot-humid regions.

15. Q1A(R2) Stability Testing Of New Drug Substances And Products
 The purpose of stability testing is to provide evidence on how the quality of a
drug substance or drug product varies with time under the influence of a variety
of environmental factors such as temperature, humidity, and light, and to
establish a retest period for the drug substance or a shelf life for the drug product
and recommended storage conditions.
Stress Testing
• Stress testing of the drug substance can help identify the likely degradation
products, which can in turn help establish the degradation pathways and the
products, which can in turn help establish the degradation pathways and the
intrinsic stability of the molecule.
• Stress testing is likely to be carried out on a single batch of the drug substance. It
should include the effect of temperatures, humidity, oxidation, and photolysis on
the drug substance.
• The testing should also evaluate the susceptibility of the drug substance to
hydrolysis across a wide range of pH values when in solution or suspension.
Selection of Batches
• Data from formal stability studies should be provided on at least three primary
batches of the drug substance.

16. Q1A(R2) Stability Testing Of New Drug Substances And Products
• and using a method of manufacture and procedure that simulates the final
process to be used for, production batches.
Container Closure System
• The stability studies should be conducted on the drug substance packaged in a
container closure system that is the same as or simulates the packaging proposed
for storage and distribution.
Specification
• Specification, which is a list of tests, reference to analytical procedures, and
proposed acceptance criteria.
proposed acceptance criteria.
• Stability studies should include testing of those attributes of the drug substance
that are susceptible to change during storage and are likely to influence quality,
safety, and/or efficacy.
Testing Frequency
• For long term studies, frequency of testing should be sufficient to establish the
stability profile of the drug substance.
• For drug substances with a proposed re-test period of at least 12 months, the
frequency of testing at the long term storage condition should normally be every
3 months over the first year, every 6 months over the second year, and annually
thereafter through the proposed re-test period.

17. Q1A(R2) Stability Testing Of New Drug Substances And Products
Storage Conditions
• In general, a drug substance should be evaluated under storage conditions (with
appropriate tolerances).
• The storage conditions and the lengths of studies chosen should be sufficient to
cover storage, shipment, and subsequent use.
• Long term, accelerated, intermediate storage conditions for drug substances are
detailed in the sections below.
