This document provides an overview of Good Laboratory Practice (GLP) principles established by the Organization for Economic Co-operation and Development (OECD). It discusses the key personnel involved in GLP studies including study directors, quality assurance personnel, and principal investigators. Facilities, equipment, test systems, standard operating procedures, study plans, and conduct of studies are also summarized in relation to adhering to GLP principles. The goal of GLP is to promote quality and validity of safety testing data for chemicals and products.
Oecd principles of GLP
- 1. Major Advisor : Dr. K. Jayakumar Speaker : Amol R. Padol CREDIT SEMINAR-I
- 3. OECD ??? 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.
- 4. 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 (Schechtman, 2007)
- 5. Good Laboratory PracticeGood Laboratory Practice 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)
- 6. 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. (Berend, 2002)
- 7. 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.
- 9. o The GLP regulations for non-clinical laboratory studies published by the US-FDA in 1976 (Baldeshwiler, 2003). 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.
- 10. 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.
- 11. SCOPESCOPE
- 12. Principles of GLP should be applied to the non-clinical safety testing of test items contained in, Pharmaceutical products Pesticide products Cosmetic products Veterinary drugs Food and feed additives Industrial chemicals.
- 13. o Test items: synthetic chemicals, natural or biological origin and, may be living organisms. o Safety studies covered by the Principles of GLP include work conducted in the laboratory, in greenhouses, and in the field (Jena et al ., 2009) o Principles of GLP apply to all non-clinical health and environmental safety studies required by regulations for the purpose of registration.
- 15. Key Personnel in GLP
- 16. Test Facility Management o The person(s) who has the authority and formal responsibility for the organisation and functioning of the test facility. Responsibilities o Maintenance of a record of the qualifications, training, experience and job description for each professional and technical individual.
- 17. o Appropriate and technically valid SOPs are established and followed. o Quality Assurance Programme is being performed in accordance with the Principles of GLP. o Individual with the appropriate qualifications, training, and experience is designated by the management as the Study Director before the study is initiated.

Dates QAP statement Description of Test Methods Results Storage (study plan, test and reference items, specimens, raw data)
- 47. Mutual Acceptance of Data o Testing of chemicals is labour-intensive and expensive, and testing the same chemical in several countries adds to the cost in time, resources and laboratory animals. o To relieve some of this burden, the OECD Council adopted the concept of MAD in 1981.
- 48. o Mutual Acceptance of Data: “Data generated in a member country in accordance with OECD Test Guidelines and Principles of GLP shall be accepted in other member countries for assessment purposes and other uses relating to the protection of human health and the environment.” (Turnheim , 2008)
- 49. o OECD Council sets out a step-wise procedure for non- OECD countries with a major chemical industry to take part in the work of OECD (Sasaki et al., 2009) o This leads to full membership in the part of OECD related to the MAD. o South Africa was the first non-OECD country to have completed this process and to have been invited to join the system as a full member.
- 50. o Slovenia and Israel - full members. o Argentina, Brazil, India (2003) , Malaysia and Singapore are the provisional adherents. o The provisional adherence procedures have begun for Thailand.
- 51. National GLP Compliance Monitoring Authority (NGCMA) o April, 2002 o Department of Science and Technology (DST). o Provisional Member of the OECD for GLP. o Head, National GLP Programme has been nominated by the Department as an Observer to the OECD’s Working Group on GLP. o functions as per OECD Norms & Principles and efforts are being made to achieve OECD recognition, so that India acquires full-member status in OECD (Stanley, 2009) There is still long way to go……………..!
- 53. o The purpose of GLP is to assure the quality and integrity of data submitted in support of the safety of regulated products. o Protocols, SOPs, adequate facilities, and equipments, identification of test substance, proper animal care, accurate recording of observations and adequate reporting of results are basic necessities for the conduct of high quality valid toxicity study.
- 54. o Test results obtained in compliance with GLP are to be mutually accepted by the health authorities and environment authorities of the OECD member states. Therefore, multiple testing can be avoided.
