How much does a rat liver response tell us about human cells?
Across 26 held-out compounds, CT-Tox achieved 0.74 rank agreement with measured human Hallmark pathway responses, versus 0.35 for copying rat responses to human genes.

Which patients will respond to immunotherapy?
Across 5 cohorts, 43% responded. In CT-Translate’s top-ranked third: 61%.
451 patients. Every prediction made by a model that never saw that patient.
Retrospective results:

Predicting patient outcomes from lab data is a long-sought goal in drug development.
Introducing CT-Translate, a preclinical-to-clinical foundation model built to do it.
In its top-ranked third of immunotherapy patients, 61% responded vs 43% overall.

One model, 69 clinical questions. In: a tumor profile, clinical details and a plain-English question. Out: a probability per patient, so patients can be ranked.
Built on CT1, our foundation model. Trained on drug screens and more than 13,000 patients across 20 studies.
It runs on-prem, frozen and versioned on a single GPU, no external calls. Your fine-tuned weights stay on your premises and run on the licensed CellType foundation model.
Built with a top-10 pharma translational team. Test it on patients you hold out:
