Noeris
AI for drug-induced liver injury
Noeris bridges animal studies to human safety decisions. We read the preclinical data pharma already generates and tell drug developers whether a molecule will injure the human liver, while it is still cheap to change course.
01 · The problem
Every drug passes a rodent study before a human sees it. Those studies are a good negative filter and a poor positive one, so liver risk is found late: in the clinic, or years after approval.

#1
reason approved drugs are withdrawn is liver injury: 81 of 462 withdrawals over six decades.3
Liver injury is a leading reason drugs fail in clinical trials.
DILI is drug-induced liver injury. IND is the Investigational New Drug application, the gate to human trials.
02 · Why now
More molecules reach the safety gate every year. Every one of them is still judged by the same rat study, read by eye.

+24%. Phase I drugs grew from 3,263 to 4,061 in three years.5 Safety is still judged by the same rat study, read by eye.6 It predicted human liver injury poorly in 2000, and it still does in 2025.1, 2

Medicare pays for Imagene's AI lung cancer test, and Paige and Ibex AI tools help pathologists diagnose cancer in routine practice.7

In 2025 the FDA's roadmap set out to cut animal testing, and ISTAND, its route for qualifying new methods, became permanent.8
03 · Approach
Rat tissue AI trained on human outcomes. Three independent witnesses, one verdict.
The molecule's structure and predicted bioactivity.
How human hepatocytes respond when exposed to the drug.
Whole-slide images from the standard rat study, read for human outcomes.
Noeris verdict
One human liver-risk score. Each witness sees different biology, so their mistakes rarely overlap.
molecule · cell · tissue · patient
Chemistry sees the molecule. Cell tests see cells in a dish. Liver injury happens in a whole organ, and only a living liver shows how it responds to the drug.
Other pathology AI learns the pathologist's read. Ours learns what happened to patients.9
A slide holds billions of pixels. A pathologist turns it into a grade. The AI reads every one of them.
Uses the rat study every drug already runs. No added cost, time, or change to the lab workflow.
04 · Results
Tested on 86 drugs with known human liver outcomes. Every one passed every preclinical check and reached the market, which makes them a harder subset.10, 16
Bars start at 0.4. An AUC of 0.5 is a coin flip, 1.0 is perfect. Today's rat pathology read scores about a coin flip.10
37 of 48
liver-toxic drugs caught at the same false-alarm rate. Pathology grades catch 17. The Noeris chemistry model, on par with the published state of the art, catches 21.10, 11
Tissue
is the witness that contributes most. Remove it and accuracy falls from 0.74 to 0.62. Remove any other witness and accuracy barely moves.12
Case study
Perhexiline, an angina drug, later withdrawn for liver injury.
Retrospective analysis on held-out predictions. Illustrative, not a prospective claim.

We run blinded retrospective pilots on partners' own compounds, using the rat studies they have already completed. We would like to hear from drug developers, CROs and investors.
