GLP and Schedule 1

Introduction
Good Laboratory Practice
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.

OECD ???
o OECD - Organization for economic co-operation and
development.
o an intergovernmental organisation.
o Representatives of 30 industrialised countries in North
America, Europe, Pacific and the European Commission.
o To co-ordinate and harmonize policies, discuss issues of
mutual concern, and work together to respond to international
problems.

o Environmental Health and Safety Division.
o The Principles of GLP have been developed to promote
the quality and validity of test data used for determining
the safety of chemicals and chemical products
o The Environmental Health and Safety Division publishes
free-ofcharge 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.

Good LaboratoryPractice
o 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.
(OECD/ENV/MC/CHEM,1998)

o Its principles are required to be followed by test
facilities carrying out studies to be submitted to
national authorities.
o Common principles for GLP facilitate the exchange of
information and prevent the emergence of non-tariff
barriers to trade.
o The issue of data quality has an
important international
dimension.
o If regulatory authorities in
countries can rely on safety test
data developed abroad,
duplicative testing can be
avoided.

o The GLP regulations for non-clinical laboratory studies
published by the US-FDA in 1976.
o The OECD Principles of GLP were first developed by
an Expert Group on GLP established in 1978 under
the Special Programme on the Control of Chemicals.
o Principles of GLP were adopted by the OECD in 1981.

o Expert Group was established in 1995 to develop a
proposal to revise the Principles of GLP.
o The Revised OECD Principles of GLP were reviewed
in the relevant policy bodies of the Organisation and
were adopted by Council on 26 November, 1997.
o Indian GLP Compliance Monitoring Authority - April,
2002.

The formal, regulatory, concept of “Good Laboratory Practice”
(GLP) originated in the USA in the 1970s because of
concerns about the validity of non-clinical safety data
submitted to the Food and Drug Administration (FDA) in the
context of New Drug Applications (NDA).
The inspection of studies and test facilities revealed instances
of inadequate planning and incompetent execution of
studies, insufficient documentation of methods and
results, and even cases of fraud.
These deficiencies were made public in the Kennedy-
Hearings of the US Congress, and the political outcome of
these hearings led to the FDA’s publication of Proposed
Regulations on GLP in 1976, with establishment of the Final
Rule in June 1979 (21 CFR 58).

WHY WAS GLP CREATED?
In the early 70’s FDA became
aware of cases of poor
laboratory practice all over the
United States.
FDA decided to do an in-depth
investigation on 40 toxicology
labs.
They discovered a lot fraudulent
activities and a lot of poor lab
practices.
Examples of some of these poor
lab practices found were:
1. Equipment not been calibrated
to standard form , therefore
giving wrong measurements.
2. Incorrect/inaccurate accounts
of the actual lab study
3. Inadequate test systems

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.
It was discovered that mice that they
had used to test cosmetics such as
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 consumption.
Those involved in production,
distribution and sales for the lab
eventually served jail time.

Need for GLP regulations:
· In pharmaceutical industries, the experiments were poor,
careless or inaccurately analysed or reported.
· Technical personnel were unaware of importance of protocol
adherence, accurate observation, accurate administration of test
substance, record keeping and record transcription.
· No critical review of data and supervision.
· No proper evaluation of all available data.
·No assurance of scientific qualification and training of personnel
involved in study.
· No proper laboratory, animal care and data management
procedure.
· Failure to verify accuracy and completeness of scientific data
before submission.
· Failure to monitor adequately studies performed by testing
facilities.
