1.GOOD LABORATORY PRACTICE
• GLP applies to nonclinical studies conducted for the assessment of the safety or
efficacy of chemicals (including pharmaceuticals).
• GLP helps assure regulatory authorities that the data submitted are a true.
• The formal regulatory concept of “good laboratory practice” (GLP) originated in
the USA in the 1970’s.
• The FDA's publication of proposed regulations on GLP in 1976, with
establishment of the final rule in june 1979 (21 CFR 58).
• In 1981 an organization named OECD produced GLP principles that are
international standard.
3

Why was GLP created?
• In the early 70’s FDA became aware of cases of ( PLP ) poor laboratory practice
all over the united states.
• FDA decided to do an in-depth investigation in 40 toxicology labs.
• They discovered a lot fraudulent activities and a lot of poor lab practices.
Examples of some of these ( PLP ) poor lab practices found were:
• Equipment not been calibrated to standard form , therefore giving wrong
measurements.
• Incorrect/inaccurate accounts of the actual lab study.
• Inadequate plan.
4

FAMOUS EXAMPLE
• One of the labs that went under such an investigation made headline
news.
• The name of the lab was industrial bio test.
• This was a big lab that ran tests for big companies such as
Procter and gamble (P&G)
• It was discovered that mice that they had used to test lotion and deodorants had
developed cancer and died.
• Industrial bio test lab threw the dead mice and covered results deeming the products
good for human use.
• Those involved in production, distribution and sales for the IBT lab eventually served
jail time.

ABOUT THE OECD
• The organization for economic co-operation and development (OECD) is an
intergovernmental organization in which representatives of 29 industrialised
countries in north America, Europe and the pacific, as well as the European
commission, meet to co-ordinate and harmonize policies, discuss issues of mutual
concern, and work together to respond to international problems.
• Most of the OECD's work is carried out by more than 200 specialized committees
and subsidiary groups composed of member country delegates. Observers from
several countries with special status at the OECD, and from interested international
organizations, attend many of the OECD's workshops and other meetings.
6

• Committees and subsidiary groups are served by the OECD secretariat, located in
Paris, France, which is organized into directorates and divisions.
• The work of the OECD related to chemical safety is carried out in the environmental
health and safety division.
• The environmental health and safety division publishes free-of charge documents in
six different series: testing and assessment; principles on good laboratory practice
and compliance monitoring; pesticides; risk management; chemical accidents and
harmonization of regulatory oversight in biotechnology.
• More information about the environmental health and safety programme and EHS
publications is available on OECD's world wide web site.
• The OECD principles of good laboratory practice were first developed by an expert
group on GLP established in 1978 under the special programme on the control of
chemicals. 7

• The GLP regulations for non-clinical laboratory studies published by the US food
and drug administration in 1976 provided the basis for the work of the expert group,
which was led by the united states and comprised experts from the following
countries and organisations: Australia, Austria, Belgium, Canada, Denmark,
France, the federal republic of Germany, Greece, Italy, Japan, The Netherlands,
New Zealand, Norway, Sweden, Switzerland, The United Kingdom, The United
States, the commission of the European communities, the world health
organisation and the international organisation for standardization.
• Those principles of GLP were formally recommended for use in member countries
by the OECD council in 1981.
8

• They were set out (in annex II) as an integral part of the council decision on mutual
acceptance of data in the assessment of chemicals, which states that “data generated
in the testing of chemicals in an OECD member country in accordance with OECD
test guidelines”and OECD principles of good laboratory practice shall be accepted in
other member countries for purposes of assessment and other uses relating to the
protection of man and the environment ”
9

SCOPE
• These principles of good laboratory practice should be applied to the non-clinical
safety testing of test items contained in pharmaceutical products, pesticide products,
cosmetic products, veterinary drugs as well as food additives, feed additives, and
industrial chemicals.
• These test items are frequently synthetic chemicals, but may be of natural or
biological origin and, in some circumstances, may be living organisms. The purpose
of testing these test items is to obtain data on their properties and/or their safety
with respect to human health and/or the environment.
• Non-clinical health and environmental safety studies covered by the principles of
good laboratory practice include work conducted in the laboratory, in greenhouses,
and in the field.
10

• Unless specifically exempted by national legislation, these principles of good
laboratory practice apply to all non-clinical health and environmental safety
studies required by regulations for the purpose of registering or licensing
pharmaceuticals, pesticides, food and feed additives, cosmetic products,
veterinary drug products and similar products, and for the regulation of industrial
chemicals.

assure that the quality assurance responsibility is being performed in accordance with
these principles of good laboratory practice;
13

G) Ensure that for each study an individual with the appropriate qualifications,
training, and experience is designated by the management as the study director
before the study is initiated. Replacement of a study director should be done
according to established procedures and should be documented.
H) Ensure, in the event of a multi-site study, that, if needed, a principal investigator
is designated, who is appropriately trained, qualified and experienced to supervise
the delegated phase(s) of the study. Replacement of a principal investigator should
be done according to established procedures and should be documented.
I) Ensure documented approval of the study plan by the study director.
