Release notes for October 2025

Safety Margin Tool

Dear Valued Customer,

We are excited for the latest release of the Safety Margin Tool. These new updates introduce several significant enhancements aimed at strengthening its capabilities in mechanistic safety assessment and polypharmacy analysis!

23 new Target-MOAs (Mechanism of Action) have been added with a total of 58 Target-MOAs, currently available in the Safety Margin Tool enhancing mechanistic understanding of adverse drug reactions and profiling compounds safety risks.

Users can now export results directly to Excel (Open XML format), simplifying data sharing and integration with other workflows. This new export option makes it easier to generate reports, collaborate with colleagues.

To enhance data interpretation, the tool now supports conversion of % inhibition and % stimulation values to IC50 and EC50 for values between 20% and 80% (assuming a slope of 1). This feature streamlines the process of deriving potency metrics and ensures greater consistency when comparing activity across targets and compounds.

We’ve also strengthened the link between the Safety Margin Tool and the PharmaPendium Drug Safety Dataset, enabling seamless access to clinical and FAERS data for deeper investigation at the drug, target, and adverse drug reaction (ADR) levels. This tighter integration empowers users to connect preclinical safety margins with real-world safety outcomes, supporting more comprehensive risk assessments.

In addition, users can now take advantage of an enhanced MedDRA lookup function that allows searching across the first, second, and fourth levels of preferred terms. For instance, users can easily find targets associated with terms such as hypotension, or explore results at higher levels like the vascular disorders system organ class. This makes it simpler to navigate complex adverse event data and identify safety signals of interest.

Users can now identify drugs that have been used in multiple Target-MOAs using dedicated flags to take selectivity aspects into the safety risk analysis. Overall, this release delivers a more connected, data-rich, and user-friendly experience. The Safety Margin Tool continues to evolve as a leading resource for evidence-based, mechanism-driven safety and polypharmacy evaluation.

What’s coming next? 

An additional 22 Target MOA will be added early 2026 expanding ADR mechanistic insights across 170+ targets. A new risk assessment method will let users choose between Conservative and Relaxed calculation options for greater flexibility.
