  1. Good Laboratory Practices(GLPs) Created by Marc S. Hulin, DVM, Dipl. ACLAM

  2. History • Until the mid 1970’s the Food and Drug Administration (FDA) assumed that reports being submitted in support of new drug or medical device applications were accurate and truthful • Two submissions aroused suspicion and resulted in “for cause” inspections of sponsor laboratory

  3. History • “For cause” means an inspection initiated by FDA when there is reason to suspect a problem in a regulated product. • Results presented to Congress: • experiments poorly conceived, executed or inaccurately analyzed • technical personnel unaware of importance of SOPs, accurate record keeping, observations, and compound administration

  4. History • Management did not assure critical review of data or proper personnel supervision • Scientific qualification and adequate personnel training were lacking • Disregard for need to observe proper lab, animal care, and data mngmt. Procedures • Sponsors failed to monitor contract testing labs • Failure to verify accuracy and completeness of scientific data

  5. History • FDA’s responsibility and authority for GLPs is derived from the Federal Food, Drug, and Cosmetic Act of 1985.

  6. GLP Coverage • Purpose of GLPs: assure the quality & integrity of data submitted to FDA in support of the safety of regulated products • GLPs have heavy emphasis on data recording, record & specimen retention • Requires each study to have a study director • Study director: ultimate responsibility for implementation of the protocol & conduct of the study

  7. GLP Coverage • Covers all nonclinical laboratory studies • Food & color additive petitions, NDA & NADA • Toxicity studies (in vitro & in vivo) • Excluded: human subject trials, clinical or field trials in animals, basic exploratory studies

  8. Definitions • Sponsor: person who initiates & supports nonclinical laboratory study, a person who submits nonclinical study to FDA or testing facility that initiates & conducts the study • Testing facility: person who actually conducts a nonclinical laboratory study • Test system: any animal, plant, or microorganism to which test or control article is administered

  9. Definitions • Specimen: any material derived from a test system for examination or analysis • Raw data: any laboratory work sheets, records, memoranda, notes or copies that are result of original observations • Quality assurance unit: monitor study conduct • Study director: individual responsible for the overall conduct of a nonclinical laboratory study

  10. Quality Assurance Unit (QAU) • QAU records are exempt from routine FDA inspections • Maintain a copy of master schedule sheet of all nonclinical laboratory studies • Inspect each study at intervals adequate to assure the integrity of the study

  11. Quality Assurance Unit (QAU) • Determine that no deviations from approved protocols or SOPs were made without proper authorization & documentation • Review the final study report to assure methods & SOPs reflect raw data

  12. Maintenance & Calibration of Equipment • Equipment shall be adequately inspected, cleaned & maintained • Equipment used for assessment of data shall be tested, calibrated and/or standardized • Scales & balances should be calibrated at regular intervals (usually ranging from 1-12 months)

  13. Standard Operating Procedures(SOPs) • Testing facility shall have SOPs adequate to insure the quality & integrity of the data generated in the course of a study • all deviations from SOPs shall be authorized by the study director & documented in the raw data

  14. Animal Care • SOPs are required for all aspects of animal care • Newly received animals shall be isolated & health status evaluated • Animals shall be free of any disease or condition that might interfere at beginning of study

  15. Animal Care • Animals of different species shall be housed in separate rooms • Feed & water analyzed periodically for contaminants • Contaminant analysis of food & water for each & every study is not a requirement nor is analysis for laundry list of contaminants
