3D InSight™ | 3D In Vitro Liver Toxicology
The liver is a primary target of drug- and chemical-induced toxicity. Liver injury contributes to numerous late-stage clinical failures and post-marketing drug withdrawals, highlighting the need for improved safety assessment strategies to protect patients and prevent costly setbacks.
A comprehensive safety assessment process that supports the selection and progression of the most promising drug candidates should include the early discontinuation of highly toxic compounds, thorough characterization of human and animal responses, and detailed investigation of the underlying mechanisms of toxicity.

Understanding species-specific differences
Toxicity can differ between animals and humans, making cross-species evaluation essential for drug safety assessment. From standard DILI testing to mechanistic assays and transcriptomic studies, use species-specific (rat, monkey, or dog) 3D liver models to flag potential risks early, de-risk preclinical findings, and evaluate translatability to humans.
