2. What is GLP?
Good Laboratory Practice (GLP) is a quality system concerned with the
organisational process and the conditions under which non-clinical health
and environmental safety studies are planned, performed, monitored,
recorded, archived and reported.

3. Historical Background
• In the early 1970s, the US Food and Drug Administration (FDA) mounted a series of
investigations in toxicology laboratories throughout the USA.
• The FDA investigated a number of cases of poor practice in toxicology laboratories
throughout the USA
• Results of this investigation in about 40 laboratories revealed many cases of poorly
managed studies, insufficient training of personnel, and some cases of deliberate
managed studies, insufficient training of personnel, and some cases of deliberate
fraud.

4. Historical Background
The FDA investigation Findings:
• Poorly-trained Study Directors and study personnel
• Poorly-designed protocols
• Protocols not followed - procedures not conducted as prescribed
• Raw data badly collected - not correctly identified - without traceability - not verified
or approved by responsible persons
or approved by responsible persons
• Lack of standardized procedures
• Poor animal husbandry
• Inadequate characterisation of test items and test systems
• Inadequate resources
• Equipment not properly calibrated or otherwise qualified
• Reports not sufficiently verified, inaccurate account of study or raw data
• Inadequate archives and retrieval processes

5. Historical Background
The results of these investigations revealed a situation that could only be dealt with by
imposing binding regulations. These regulations are the GLP regulations.
• Introduce a new regulation to cover NON-CLINICAL SAFETY STUDIES

8. Scope of GLP (OECD)
• Principles of GLP apply to all non-clinical health and environmental
safety studies required by regulations for the purpose of registering
or licensing -
• Pharmaceuticals
• Pesticides
• Pesticides
• Food and feed additives
• Cosmetic products
• Veterinary drug products and similar products
• Industrial chemicals

9. GLP Principles

10. THE FUNDAMENTAL POINTS OF GLP
• The GLP regulations set out the rules for good practice and help researchers
perform their work in compliance with their own pre-established plans and
standardized procedures.
• The regulations are not concerned with the scientific or technical content of
the research programmes. Nor do they aim to assess the scientific value of
the research programmes. Nor do they aim to assess the scientific value of
the studies.
• All GLP texts, irrespective of their origin, stress the importance of the
following five points:
1. Resources: organization, personnel, facilities and equipment
2. Characterization: test items and test systems
3. Rules: study plans (or protocols) and written procedures
4. Results: raw data, final report and archives
5. Quality assurance.

11. 1. Resources
Organization and personnel
• GLP regulations require that the structure of R&D organizations and the
responsibilities of R&D personnel be clearly defined.
• GLP also stresses that there should be sufficient staff to perform the tasks required.
• The qualifications and the training of staff must also be defined and documented.
• The qualifications and the training of staff must also be defined and documented.
Facilities and equipment
• The regulations emphasize the need for sufficient facilities and equipment to perform
the studies.
• All equipment must be in working order. To ensure this, a strict programme of
qualification, calibration and maintenance must be adopted.

12. 2. Characterization
• In order to perform a study correctly, it is essential to know as much as possible
about the materials used during the study.
• For studies that evaluate the properties of pharmaceutical compounds during non-
clinical studies, it is a prerequisite to have details about the test item and the test
system (often an animal or plant) to which the test item is to be administered.
system (often an animal or plant) to which the test item is to be administered.

13. 3. Rules
Protocols and written procedures
• The main steps of research studies are prescribed in the study plan or protocol.
• Being able to repeat studies and obtain similar results is a sine qua non of mutual
acceptance of data and, indeed, a central tenet of the scientific method, so the
details of routine procedures must also be available to scientists involved in the
details of routine procedures must also be available to scientists involved in the
study.
• However, the protocol, which provides the experimental design and timeframe for the
study, does not contain all the technical detail necessary to conduct the study. These
details are found in written standard operating procedures (SOPs).
• With the protocol and the SOPs it should be possible to repeat the study exactly, if
necessary.

14. 4. Results
Raw data
• All studies generate raw data. These are the outcome of research and form the basis for
establishing scientific interpretations and arriving at conclusions. The raw data must also
reflect the procedures and conditions of the study.
Final Report
Final Report
• The study report contains an account of the way in which the study was performed,
incorporates the study results and includes the scientific interpretation of the data. The
report is provided to regulatory authorities as part of the submission for registration and
marketing approval.
Archives
• Storage of records must ensure safekeeping for many years and allow for prompt retrieval.

15. 5. Quality Assurance
• Quality assurance (QA), as defined by GLP, is a team of persons (often called the
quality assurance unit – QAU) charged with assuring management that GLP
compliance has been attained within the laboratory.
QA must be independent from scientists involved in the operational aspects of the
• QA must be independent from scientists involved in the operational aspects of the
study being performed. QA functions as a witness to the whole non-clinical research
process.

16. THE OECD GLP PRINCIPLES
• GLP started when the FDA issued mandatory GLP requirements on 20 June 1979.
• The FDA subsequently revised these regulations a number of times but it has
never altered its scope; regulations still apply to non-clinical safety studies
applied to drugs.
• Preliminary pharmacological studies and pharmacokinetic studies not designed
to test safety are still exempt from GLP requirements.
• A little later, the OECD introduced the OECD Principles for GLP (GLP Principles)
concerning the safety testing of any chemical substance.
