The final report is the definitive document that presents the results, analysis, and conclusions of a GLP study and must accurately reflect the raw data and study conduct. The OECD GLP Principles specify that each final report be signed and dated by the Study Director, Principal Investigators, and other contributing scientists. The report serves as the primary submission document for regulatory authorities.
Report Structure
A GLP final report must include the study and test facility identification, the study plan reference, experimental start and completion dates, and a description of the test and reference items. It must present the experimental design, methods, results, statistical analyses, and conclusions. A Quality Assurance Unit (QAU) statement is included, confirming the dates and types of inspections conducted and the dates findings were reported to management.
Content Requirements
The report must clearly describe all materials, methods, and procedures used, including any deviations from the study plan and their potential impact on study integrity. All data, summaries, and analyses must be presented in a clear, organized format that supports the conclusions drawn. Raw data and supporting documentation are referenced but not typically included in the report itself.
Certification
The Study Director certifies the final report by signing and dating a GLP compliance statement, declaring that the study was conducted in accordance with GLP principles and that the report accurately presents the study data. Each Principal Investigator signs for data generated at their respective site. The report may also include signed statements from other contributors such as pathologists or analytical chemists.
Archiving
The signed original final report, including all amendments and appendices, is archived along with the study plan, raw data, and QAU records. Reports must be retained for the period specified by applicable regulations, typically at least five to fifteen years after study completion. Electronic report files must be stored in a format that ensures long-term readability.
Conclusion
The final report is the culmination of all study activities and the primary basis for regulatory decision-making. Meticulous preparation, thorough review, and accurate certification are essential to ensure that the report meets GLP standards and supports product approval. A well-prepared report reflects the quality and integrity of the entire study process.
