in vivo PK (developed by insitro)
Model

The in vivo PK model developed for Lilly by insitro predicts preclinical intravenous pharmacokinetics for small molecules directly from chemical structure — plasma clearance, mean residence time, and volume of distribution at steady state, each across mouse, rat, dog and monkey.
It was developed by insitro for Lilly trained on Lilly's proprietary in vivo pharmacokinetic studies alongside a much larger corpus of Lilly in vitro ADME and physicochemical data. It is built for scientists who need to prioritize compounds on likely in vivo behavior before committing to animal studies.

What does the model provide?
  • Plasma clearance, mean residence time, and volume of distribution at steady state, in each of mouse, rat, dog and monkey.

  • A cross-species view in a single run, so a compound's predicted profile can be read across all four preclinical species together.

  • A shared molecular representation learned through joint multitask training on both from Lilly's much larger in vitro ADME and physicochemical collections and the in vivo PK endpoints. In vivo pharmacokinetic data is scarce by nature, and this is what allows the model to generalize beyond the compounds with in vivo PK data.

Technical specifications
Modality
Small molecule.
Input format
CSV, one row per molecule, containing a single valid small-molecule SMILES string. The SMILES column is auto-detected; all other columns are passed through to the output unchanged.
Output format
The uploaded file is returned with one prediction column per endpoint. A row whose structure cannot be parsed is returned with empty predictions rather than being dropped from the file.
Training data type
Lilly proprietary in vivo intravenous pharmacokinetic studies, trained jointly with Lilly in vitro ADME and physicochemical assay collections. Model developed for Lilly by insitro using Lilly data.
Predicted endpoint(s)
Correlation and absolute error against measured values on a held-out test split, for all twelve endpoints. Splits assign whole structural clusters rather than individual molecules, so structurally similar compounds cannot straddle the train/test boundary, and every measurement for a given molecule falls in the same split.

FAQs
What is this model best used for?
Ranking and triaging compounds on likely in vivo behavior before committing to animal studies and flagging molecules at the extremes of a pharmacokinetic parameter. It is a prioritization tool, not a substitute for the study it predicts.
How accurate should I expect it to be?
Errors are on a logarithmic scale, so treat a prediction as indicating the right order of magnitude and the right rank. Volume of distribution predicts more reliably than clearance or mean residence time in every species, and volume of distribution in the larger species is the strongest part of the set. Rodent clearance and mean residence time are the weakest — use those comparatively rather than absolutely.
Why is it trained on in vitro data as well as in vivo?
Far more compounds carry in vitro ADME and physicochemical measurements than have been through a full intravenous pharmacokinetic study. Training jointly lets the shared encoder learn chemistry from that larger corpus, while leveraging the relationships between the in vitro and in vivo endpoints, which the twelve in vivo endpoints then inherit.
Does it cover oral dosing?
No. All twelve endpoints derive from intravenous studies. Oral exposure, bioavailability and absorption are out of scope for this release.
