Data Sources You Must Harmonise Before Drafting Periodic Reports

Context

In the domain of pharmacovigilance, the preparation of periodic safety update reports (PSURs), periodic benefit-risk evaluation reports (PBRERs), and development safety update reports (DSURs) is a critical process aimed at ensuring drug safety and compliance with global regulations. The integrity and accuracy of these reports hinge on the harmonization of various data sources. Regulatory Affairs (RA) professionals are tasked with ensuring that the information dedicated to drug safety is comprehensive and meets the expectations set forth by regulatory bodies such as the FDA, EMA, and MHRA.

Legal/Regulatory Basis

The legal basis for PSURs, PBRERs, and DSURs is encapsulated in several critical regulations and guidelines, which ensure a unified approach to drug safety reporting across jurisdictions.

  • FDA Regulations: The FDA outlines the requirements for periodic safety reporting under 21 CFR Part 314, which applies to new drug applications and indicates how sponsors must report information related to adverse events.
  • European Union Guidelines: In the EU, the requirements are detailed in Commission Implementing Regulation (EU) No 520/2012 and the GVP (Good Pharmacovigilance Practices) guidelines, which provide a framework for the preparation and submission of PSURs
and PBRERs.
  • UK Regulations: After Brexit, the MHRA issued guidelines reflecting its needs for pharmacovigilance, aligning closely with EU regulations to ensure continued safety standards.
  • ICH E2C (R2) Guidelines: The International Council for Harmonisation (ICH) provides quality guidelines for the preparation of PSURs that are recognized internationally and guide RA professionals on periodic reporting.
  • Documentation

    Documenting the necessary data for periodic safety reports involves a multi-faceted approach that requires meticulous attention to detail. Effective documentation minimizes the risk of common deficiencies during regulatory review and approval processes.

    Essential Data Sources

    To draft comprehensive periodic reports, RA professionals should harmonize data from the following sources:

    • Adverse Event Reports: These comprise both serious and non-serious incidents, collected from various stakeholders, healthcare professionals, and patients.
    • Clinical Trial Data: Information gathered during clinical trials provides essential insight into adverse reactions and overall drug safety.
    • Post-Marketing Surveillance: Continuous monitoring and evaluation of drugs on the market help identify safety signals and trends not observed during clinical studies.
    • Literature Reviews: An exhaustive search of published literature is crucial to capture real-world data on drug safety.
    • Risk Management Plans: Continuous risk evaluation and management data are critical for the reassessment of drug safety profiles.

    Document Structure and Content

    When compiling a PSUR, PBRER, or DSUR, it is essential to adhere to a standardized template structured as follows:

    • Introduction: Summary of the report and objectives.
    • Product Information: Drug details, including active ingredients and dosage forms.
    • Safety Data: Comprehensive summary of adverse events, including frequency, severity, and outcomes.
    • Benefit-Risk Evaluation: An analysis comparing the documented risks against the benefits observed.
    • Conclusion and Recommendations: Summary of safety assessments with proposed actions if necessary.

    Review/Approval Flow

    The process of reviewing and approving periodic safety reports involves multiple stakeholders within the pharmaceutical organization and regulatory agencies. Understanding this flow is critical for timely and compliant submissions.

    Internal Review Process

    Typically, the internal review process for a PSUR or PBRER includes the following steps:

    1. Drafting: The initial report is drafted by the pharmacovigilance team, incorporating all relevant data sources.
    2. Expert Review: Experts including clinical, regulatory, and medical safety officers review the draft for accuracy and comprehensiveness.
    3. Quality Assurance: A dedicated QA team verifies that the report complies with standard operating procedures (SOPs) and regulatory requirements.
    4. Finalization: Recommendations are incorporated, and a final version is prepared for submission.
    5. Submission: The report is submitted electronically to the relevant authorities via designated portals.

    Agency Review Process

    Upon receipt of the periodic report, regulatory agencies undertake a systematic review which encompasses:

    • Assessment of Report Quality: Agencies evaluate the completeness and adherence to regulatory frameworks.
    • Safety Signal Detection: Reviewing adverse event data to identify new safety signals.
    • Risk Communication: Agencies may require risk minimization measures or signal alerts to be communicated to healthcare professionals.
    • Response Timeframes: Compliance with agencies’ timelines for responses to any deficiencies detected.

    Common Deficiencies

    Understanding and anticipating potential deficiencies can reduce the likelihood of regulatory setbacks during reviews. Common deficiencies noted by regulatory agencies include:

    Inadequate Data Integration

    One of the most frequently observed issues is the lack of harmonization across data sources. Regulatory agencies expect a cohesive and integrated approach to data presentation. Inadequacies in this area can lead to misinterpretation and an incomplete view of the drug’s safety profile.

    Poor Justification of Safety Signals

    When safety signals or changes in risk benefit assessments are not sufficiently justified, regulatory agencies may raise concerns. It is essential to provide robust arguments backed by clear evidence when changes to risk management plans are proposed.

    Failure to Address Previous Agency Queries

    There is an expectation to respond to previous agency feedback in subsequent periodic reports. Failing to provide clarifications or actions taken in response to raised issues can prompt further scrutiny.

    Insufficient Benefit-Risk Assessment

    Reports lacking a thorough evaluation of the benefit-risk balance may be rejected. Regular assessment using frameworks provided in ICH E2C guidelines should be integrated into report drafting.

    RA-Specific Decision Points

    Regulatory Affairs professionals must navigate critical decision points in the context of developing these reports. Understanding when to file variations versus new applications is pivotal.

    Filing Variations vs. New Applications

    Deciding whether to submit a variation (minor change) or a new application largely depends on the type of change involved:

    • Filing as a Variation: If there are updates related to product information, safety data updates that do not constitute a global change, or dosage form adjustments.
    • Filing as a New Application: If the changes relate to a new therapeutic indication or substantial alterations that impact the product’s risk-benefit profile.

    Justifying Bridging Data

    In scenarios where bridging data is required for products marketed in multiple jurisdictions, it is essential to provide a scientific rationale that explains why the data suffices to demonstrate safety and efficacy across populations. The justification should encompass:

    • Scientific Evidence: Highlight relevant literature and data supporting the bridging approach.
    • Regulatory Guidance: Reference corresponding GVP guidelines to underpin the decision, demonstrating compliance with frameworks set by regulatory authorities.
    • Clinical Relevance: Discuss clinical trial outcomes reflecting similar patient populations or disease states.

    Conclusion

    In summary, the preparation of periodic safety reports such as PSURs, PBRERs, and DSURs requires significant effort, harmonizing diverse data sources, and adhering to regulatory frameworks set forth by authorities in the US, UK, and EU. Regulatory Affairs professionals play a crucial role in shaping the narrative of safety, drawing from various data to provide a complete picture. Understanding the review processes, potential deficiencies, and decision-making pathways ensures that these reports meet agency expectations and ultimately contribute to patient safety.
