A sensitive and specific means to predict hepatotoxicity
Employing our Liver-on-a-chip hepatic co-culture model (evaluated by our collaborators at the U.S. FDA), our DILI in vitro Service can screen your small molecules, antibodies, ASO, and gene editing reagents to establish human DILI risk.
Alternatively, use our Service to perform comparative cross-species (human, rat and dog) Liver-on-a-chip studies. De-risk development and minimize animal testing by flagging interspecies differences early, or use the Service to provide clarity regarding which in vivo species is more human predictive when uncertainties arise.

Service overview:
Our Service assesses at least six hepatic health parameters simultaneously, including clinical markers of liver injury. This approach achieves the sensitivity and specificity required to identify hepatotoxins missed in animals, and other in vitro assays.
- Test a range of drugs to enable lead or candidate selection
- Derive cross-species data to better inform animal studies, or explain non-concordant findings
- Explore DILI under a range of conditions: healthy, inflammation, steatotic
- Test highly human-specific new modalities
- Compare acute vs chronic toxicity responses
- Investigate drug–drug interaction events
- Check for CYP induction or inhibition
- Use retained samples to understand drug metabolism
- Bespoke human multi-organ, or studies with circulating human immune cells available on request
Customer feedback
I worked with CN Bio on a DILI Services project to predict which formulation of the same test agent would be safe for humans. Previous In vivo studies demonstrated inter-species differences between the formulations in animals but thanks to the expertise of CN Bio, I was able to rapidly gain human-relevant data that helped to move my project forward.

Why choose this DILI in vitro Service?
Early insights
Flag interspecies differences early to better inform in vivo study design
Protect study validity
Mitigate the risk of late-stage conflicting data, or drug misclassification
Reduce animal use
Safeguard and reduce unnecessary in vivo animal use

Address the cause
Identify the mechanism of human DILI to address the cause
Mitigate risk
Mitigate the risk of late-stage conflicting data, or drug misclassification
How the service works:
Through the co-culture of primary human hepatocytes and non-parenchymal cells, and the evaluation of multiple endpoints, our assay offers a complete assessment of DILI risk.
Couple with comparative rat (Sprague-Dawley) and/ or dog (Beagle) primary hepatocyte assays for cross-species insights.
Our service provides higher content data than spheroids and sufficient throughput to deliver concentration-response curves.
Your dedicated contact will work collaboratively with you from the start to the end of the project.

Related applications
Drug-induced liver injury
Our human DILI assay can assess the toxicity of a wide range of entities (small molecules, protein, ASOs, AAVs, etc) in the presence or absence of liver disease.
Human and cross-species DILI assays facilitate more informed predictions of inter-species differences in response to acute, or repeated drug exposure via in vivo translatable endpoints.
