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

CYP Inhibition Blind Challenge


Our current blind challenge focuses on cytochrome P450 (CYP) inhibition across four major isoforms — CYP3A4, CYP2C9, CYP2D6, and CYP1A2 — a critical ADMET liability for drug-drug interactions and regulatory compliance. Built with Octant and the UCSF Fraser lab, the challenge covers both direct and time-dependent inhibition on compounds drawn from the Enamine DDS10 diversity set and FDA-approved drugs.

Direct Inhibition (Regression)
Predict pIC50 values across all four CYP isoforms for a 750-compound test set.
Time-Dependent Inhibition (Classification)
Classify mechanism-based inhibition (2-fold IC50 shift) for CYP3A4 and CYP2D6.
