Good Laboratory Practice (GLP)
• OECD GLP Principles (revised 1997)
• GLP principles were developed to promote the quality and validity of non-clinical safety data
because of serious data manipulation issues
• basis for corresponding national GLP-regulations in most countries
GLP status is prerequisite for mutual international regulatory acceptance of non-clinical
safety data !
24/11/2017LRI – Data Management Ensuring Factual Correctness & Reproducibility
-
Basic GLP Principles
Organizational aspects
e.g. independent quality assurance
Complete (study) planning in advance
Standard Operating Procedures (SOP) system, study plan
Final report must reflect raw data
Raw data recording, processing and integrity
Archiving
Full retrospective reproducibility of studies

Raw Data
Definition in GLP principles
(OECD)
„Raw data means all original test facility
records and documentation, (or verified copies
thereof), which are the result of the original
observations and activities in a study.”
24/11/2017LRI – Data Management Ensuring Factual Correctness & Reproducibility
To be defined for each data recording system raw data must not be susceptible tomanipulation
Paper or electronic raw data ?New technologieshuge amount of electronic raw data
-
Data Processing
Report data must be reproducible from raw data ! Documention of all relevant processing steps!
Could mean a lot of documentation
Uncontrolled data „manipulation“ impermissible ! Initial data entry must not be deleted !
All Data changes/ corrections to be justified
Data recording/processing software should have audit trail Software development
Commitment to and control of
„manual“ audit trail ?
24/11/2017LRI – Data Management Ensuring Factual Correctness & Reproducibility
-
Validation: Software and Procedures
Do functions work correctly ?
„Black box“ software validation possible
Proper data protection / storage ensured?
Software access control ?
No software administrator rights for users ?
Audit trail function ?

Validation: IT Systems
Before IT Systems are used in a GLP setting, they must be validated
Ensure that data produced can be stored in a GLP compliant way
Blackbox-Validation is permitted Show via alternative ways that output is correct!

2. Upload to MetaMap®Tox Data base
3. Use of algorithms to compare with data base- evaluation of single metabolite changes- comparison against toxicity patterns- correlation against other treatments
4. Evaluation in MetaMap®Tox How to deal with old, non-GLP data?

Good Laboratory Practice (GLP)
needed for regulatory acceptance
= good documentation & transparency
very helpful in doing a good study (not necessarily a relevant one)
is a culture / mindset
