Maria Castellanos Hugo MacDermott-Opeskin It’s been more than a month since the OpenADMET-ExpansionRx challenge wrapped up, but the conversation is just getting started. Launched on October 27, 2025, the challenge saw hundreds of participants pushing the boundaries of ADMET endpoint prediction. Seeing this level of engagement, we are more
Introduction OpenADMET facilitates blind challenges to bridge the gap between computational modeling and experimental reality in drug discovery. By providing high-quality, blinded datasets, these challenges offer a transparent benchmark for evaluating the predictive power of ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) models. We are excited to present our next

It depends on the liver.” - William James, American philosopher Introduction As the primary site of drug metabolism, the liver is a key determinant of a compound's pharmacokinetics (PK). Rates of hepatic metabolism
Maria Castellanos Hugo MacDermott-Opeskin Jon Ainsley Pat Walters The ExpansionRx challenge, launched on October 27, 2025, closed two weeks ago! We are extremely grateful to everyone who participated and made this incredible learning experience possible for the ML and ADMET communities. After releasing the final leaderboard in our previous blogpost.

At OpenADMET we aim to address the unpredictable nature of these properties through open science, generating high-quality experimental data and building robust predictive models of ADMET
Authors: Devany West, Ph. D., Software Scientist, and Cynthia Xu, Research Software Engineer OpenADMET’s mission is to develop ADMET models for drug discovery Drug discovery is a risky venture: it is estimated that nearly 30% of all drug candidates fail due to safety concerns, and as many as 20%

Or, how do you know what you don't know? Author: Sean Colby, Data Scientist, OpenADMET Introduction At OpenADMET, we are chartered with providing data and models in support of screening molecules against anti-targets and other adverse ADMET (absorbtion, distribution, metabolism, excretion, toxicity) properties. As a motivating example, we

At OpenADMET we address the unpredictable nature of these properties through open science, generating experimental data and building predictive models of ADMET properties. A key
Small molecules continue to be the bricks and mortar of drug discovery globally, accounting for ~75% of FDA approvals over the last decade. Oral bioavailability, easily tunable properties, modulation of a wide range of mechanisms, and ease of manufacturing make small molecules highly attractive as therapeutic agents. Moreover, emerging small

Starting today, September 15, 2025, I will assume a new role as Chief Scientist at OpenADMET, an open science initiative that combines high-throughput experimentation, computation, and structural biology to enhance the understanding and prediction of absorption, distribution, metabolism, excretion,
Small molecule therapies have always been and continue to be the dominant way we treat diseases worldwide. Small molecules have unique advantages such as cost, scalability, convenience, the ability to get into every organ/cell and modulate a wide variety of targets/mechanisms – especially as compared to other modalities like
