SOP for Conducting Preclinical GLP Studies

Standard Operating Procedure (SOP) for Conducting Preclinical GLP Studies

1) Purpose

The purpose of this Standard Operating Procedure (SOP) is to define the procedures for conducting preclinical studies in compliance with Good Laboratory Practice (GLP). GLP is a set of principles that ensures the quality, integrity, and reproducibility of data in non-clinical laboratory studies. This SOP outlines the requirements for study planning, execution, documentation, and reporting to ensure that preclinical studies are conducted according to GLP standards.

2) Scope

This SOP applies to all personnel involved in conducting preclinical studies that must comply with GLP standards. It covers all phases of a study, from planning and protocol development to the final report and archival of data. The SOP is relevant to researchers, toxicologists, pharmacologists, study directors, quality assurance (QA) personnel, and laboratory technicians responsible for preclinical study execution and documentation.

3) Responsibilities

  • Study Directors: Oversee the planning, execution, and reporting of the study, ensuring compliance with GLP guidelines and internal protocols.
  • Researchers/Pharmacologists/Toxicologists: Design and conduct the study according to the study protocol and GLP standards, ensuring accurate data collection and interpretation.
  • Quality Assurance (QA): Ensure that all aspects of the study are conducted in compliance with GLP standards. QA personnel must perform audits
to verify data integrity and regulatory compliance.
  • Laboratory Technicians: Conduct laboratory procedures in compliance with the study protocol, ensuring that all samples are handled, stored, and analyzed according to GLP standards.
  • Data Analysts: Analyze study data and ensure that statistical methods are applied correctly, with results documented according to GLP standards.

    • 4) Procedure

    The following steps outline the procedure for conducting preclinical GLP studies:

    1. Step 1: Study Planning and Protocol Development
      1. Define the objectives of the study, including the desired endpoints (e.g., efficacy, toxicity, pharmacokinetics).
      2. Select the appropriate animal model(s) based on the study’s objectives and ensure that they are suitable for the experimental design.
      3. Develop the study protocol, including the following details:
        • Study design and dose selection
        • Animal model and group size
        • Administration route and frequency of dosing
        • Methods for sample collection and analysis
        • Statistical analysis plan
        • Monitoring procedures for animal health and welfare
      4. Ensure that the protocol includes detailed instructions on GLP-compliant practices, such as sample handling, documentation, and reporting.
    2. Step 2: Approval of the Protocol
      1. Submit the study protocol to the QA team for review and approval.
      2. Ensure that the protocol is reviewed for adherence to GLP standards, including the study design, endpoints, and statistical analysis plan.
      3. After QA approval, ensure that the study protocol is signed by all key personnel involved in the study.
    3. Step 3: Study Execution
      1. Administer the test substance according to the approved study protocol and ensure that all procedures are followed strictly.
      2. Monitor the animals regularly for any signs of toxicity, adverse reactions, or unexpected outcomes. Record observations in real-time.
      3. Collect biological samples (e.g., blood, urine, tissues) as specified in the protocol for further analysis.
      4. Ensure that all equipment used for testing is calibrated, cleaned, and maintained according to GLP standards.
      5. Ensure that all samples are handled, labeled, and stored according to GLP standards to maintain sample integrity.
    4. Step 4: Data Collection and Documentation
      1. Record all data in laboratory notebooks or electronic systems that are GLP-compliant and ensure that they are signed and dated by the person responsible for the data.
      2. Ensure that raw data is legible, complete, and accurately transcribed into the study records.
      3. Ensure that any deviations from the protocol are documented and justified in the study report.
    5. Step 5: Data Analysis and Interpretation
      1. Analyze the collected data using appropriate statistical methods as specified in the study protocol.
      2. Ensure that the data analysis is objective, accurate, and reflects the study’s objectives and endpoints.
      3. Interpret the results in the context of the study, providing insights into the safety, efficacy, or pharmacokinetics of the test substance.
    6. Step 6: Reporting and Documentation
      1. Prepare a final study report summarizing the methodology, data, statistical analysis, and interpretation of the results.
      2. Ensure that the report complies with GLP standards and contains all required information, including raw data, observations, and analysis results.
      3. Include any protocol deviations and a discussion of their impact on the study’s conclusions.
      4. Ensure that the report is reviewed and approved by the Study Director and QA team before final submission.
    7. Step 7: Archiving of Study Data
      1. Ensure that all raw data, study records, and final reports are securely archived in compliance with GLP standards for future reference and regulatory review.
      2. Ensure that all records are stored in a manner that allows easy retrieval and ensures their integrity over time.
    8. Step 8: Sample Disposal
      1. Dispose of all biological samples, chemicals, and laboratory waste according to biosafety and waste disposal regulations to minimize contamination risks.
      2. Ensure that all hazardous waste, such as biological samples or chemicals, is disposed of in designated biohazard or chemical waste containers.

    5) Documents

    The following documents should be maintained during the preclinical study process:

    1. Study Protocols
    2. Raw Data from the Study
    3. Study Reports
    4. Animal Health and Welfare Monitoring Logs
    5. Calibration and Maintenance Logs for Equipment
    6. Study Deviations and Justifications
    7. Waste Disposal Records
