PharmaPendium Safety Margin Tool Update

Expanded Target–MoA Coverage, Flexible Risk Assessment, and Historical Results Export

Release summary

This update expands and improves the scientific coverage of the PharmaPendium Safety Margin Tool and introduces greater flexibility in how users assess potential safety risk.

This release includes:

  • Expanded and refined coverage across 79 Target–Mechanism of Action (MoA) combinations
  • New Conservative and Relaxed assessment methods
  • Historical results export – the ability to retrieve and export results from previous tool versions

What’s new

  1. Expanded and improved Target–MoA coverage

    The Safety Margin Tool now supports a total of 79 Target–MoA combinations. Existing Target–MoAs have also been enhanced where applicable through:

    • Addition of new drugs
    • Improved drug selection
    • Refined parameter-value selection and optimization

    These improvements strengthen the evidence base used in safety-margin calculations and help ensure that assessments reflect the most appropriate available drug and parameter data.

  2. New safety-risk assessment methods

    Users can now select between two additional assessment approaches according to their scientific objective and tolerance for risk:

    Conservative assessment

    Designed to reduce the risk of false negatives. It applies a more cautious assessment so that potential safety concerns are less likely to be missed. This approach may be appropriate when the cost of overlooking a possible safety liability is especially high.

    Relaxed assessment

    Designed to reduce the risk of false positives. It applies a less restrictive assessment to help avoid unnecessarily flagging findings as potential risks. This approach may be appropriate when users need greater specificity and want to reduce over-identification of safety concerns.

    The two methods allow users to align the assessment with the needs of the program, decision context, and preferred balance between sensitivity and specificity.

  3. Historical results export

    A new export option allows users to:

    • Retrieve results generated using previous versions of the Safety Margin Tool
    • Download historical assessment results

    This feature improves transparency and makes it easier to understand how assessments may have changed as the tool’s Target–MoA coverage, drug selection, parameter selection, and assessment logic have evolved.

    Customer benefits

    Enhancement

    Customer value

    2 New Target-MoAs with a current total of 79 Target–MoAs

    Broader coverage of safety-relevant target and mechanism relationships

    Additional drugs

    More evidence available for assessment

    Improved drug and parameter selection

    More relevant inputs and more accurate safety-margin estimations

    Conservative assessment

    Greater sensitivity to potential safety liabilities and lower risk of false negatives

    Relaxed assessment

Important assessment note:

The Conservative and Relaxed methods support different assessment priorities:

  • Use Conservative when minimizing the chance of missing a potential safety concern is the primary objective.
  • Use Relaxed when minimizing unnecessary safety flags is the primary objective.

Assessment of results should continue to be interpreted alongside the underlying scientific evidence and expert judgment.
