INTRODUCTION TO GLP
•Definition:A quality system concerned with the
organizational process and conditions under which
non-clinical health and environmental safety studies
are planned, performed, monitored, recorded, and
reported.
•Origin: Developed in the 1970s to ensure the
integrity of laboratory studies.

IMPORTANCE OF GLP
•Ensures reliability and reproducibility of
data.
• Facilitates regulatory acceptance of study
results.
• Prevents fraudulent practices in research.

OECD GLP -OVERVIEW

•Organization for Economic Co-operation and
Development (OECD) established international GLP
principles.
•Ensures mutual acceptance of data (MAD) across
member countries.
•Regulates non-clinical safety studies for chemicals,
pharmaceuticals, and pesticides.

TYPES OF TESTSCARRIED OUT IN
FACILITIES UNDER GLP
a) The OECD Principles of GLP concern “non-clinical” testing of a chemical or chemical product, examined
under laboratory conditions or in the environment, including work conducted in greenhouses and in the
field. They do not include studies which use human subjects.
b) Examples of studies carried out under GLP include, inter alia:
i) physical-chemical testing;
ii) toxicity studies;
iii) mutagenicity studies;
iv) the environmental toxicity studies on aquatic and terrestrial organisms;
v) studies on behaviour in water, soil and air; bioaccumulation;
vi) studies to determine pesticide residues in food or animal feedstuffs;
vii) studies on effects on mesocosms and natural ecosystems; and
viii) analytical and clinical chemistry testing.
7.
7
TYPES OF CHEMICALSCOVERED BY
THE OECD PRINCIPLES OF GLP TEST
The OECD Principles of GLP apply to the non-clinical safety testing of test items contained in:
i) pharmaceutical products;
ii) pesticide products;
iii) cosmetic product;
iv) veterinary drugs;
v) food additives;
vi) feed additives; and
vii) industrial chemicals.
Depending on the jurisdiction, the Principles of GLP may also be applied to non-clinical safety testing
of other regulated products, such as medical devices.
8.
OECD GLP -COMPLIANCE
MONITORING
• National authorities monitor compliance through
inspections and audits.
• A test facility which has been subject to periodic
inspections by a compliance monitoring
programme (CMP,) and found to be operating in
compliance with the Principles of GLP, is recognised
as a GLP compliant test facility.
• Non-compliance may result in rejection of study
data.
• Ensures reliability for international regulatory
submissions.

OECD GLP -MUTUAL ACCEPTANCE OF
DATA (MAD)
• A study conducted under OECD GLP in one member country is
accepted in others.
• Reduces redundant testing and promotes global harmonization.

KEY EVENTS (DAYS2-3)
Study Day Event
Day 2
High dose females showed clinical signs of
toxicity after AM dose, worsening after PM
dose. No signs in males or lower dose
females.
Day 3 (AM)
High dose females showed more severe
toxicity. High dose males showed minimal
signs. Lower dose groups and controls
remained normal. Affected animals showed
signs of dehydration and renal impairment.
Day 3 (Noon)
Study Director stopped dosing high dose
females, created a Protocol Amendment, and
notified staff.
All animals except high dose females were

PROTOCOL AMENDMENT ANDSTUDY
CONTINUATION
Study Day Event
Day 4
All animals except high dose females dosed
per protocol. Sponsor and Study Director
signed the Protocol Amendment, and it was
distributed.
Days 5-28 & Recovery
Remaining animals dosed per protocol. High
dose males showed minimal toxicity, but
recovered. Renal impairment observed in mid-
and high-dose animals.
Necropsy & Histopathology
No test article-related findings at necropsy.
Histopathology showed dose-dependent renal
epithelial cell damage.

28
• In thestudy described, did a protocol deviation occur?
A. No, the Protocol Amendment covered the change in dosing
B. No, the Study Director email covered the change in dosing
C. Yes, the change in dosing was not covered by the Protocol
Amendment
D. No, the stopped dosing was due to animal welfare
29.
29
• Correct Answer:C. Yes, the change in dosing was not
covered by the Protocol Amendment.
• Explanation:The dosing change occurred before the
Protocol Amendment was finalized and distributed. This
constitutes a deviation from the approved protocol.
30.
30
REGULATORY OBSERVATION
• Observation:The quality assurance unit failed to determine
whether any deviations from approved protocols or
standard operating procedures had been made without
proper authorization and documentation.
• Regulation Cited: 21 CFR 58.35(b)(5)
• Implication: This highlights the importance of proper
documentation and QAU oversight in GLP studies to ensure
protocol adherence.

CONCLUSION
• GLP ensuresthe integrity of non-clinical safety data.
• OECD GLP principles promote global harmonization.
• Compliance is essential for regulatory approvals and scientific credibility.
