Blind Challenges


OpenADMET runs community blind challenges to benchmark predictive models on realistic drug discovery datasets. These challenges create rigorous, transparent tests of performance while helping release valuable datasets and methods to the broader community.

Current Challenge

Predicting PXR Induction


Our current blind challenge focuses on human PXR induction, an important ADMET liability associated with drug-drug interactions, hepatotoxicity, and late-stage development risk. The challenge includes both an activity prediction track and a structure prediction track, built on a large OpenADMET-generated dataset designed to resemble realistic lead-optimization workflows.

Activity Track
Predict pEC50 values for a blinded test set of PXR-active compounds.
Structure Track
Predict bound structures for PXR ligands.
Open Benchmarking
Transparent evaluation on blinded experimental data.

2025–2026
ExpansionRx–OpenADMET Blind Challenge

A lead-optimization-style blind challenge based on real-world ADMET data from Expansion Therapeutics. Participants predicted nine ADMET endpoints using earlier-stage molecules to forecast late-stage compounds.
