VivoSim Labs (Nasdaq: VIVS) announced plans to develop a rat liver model to complement its existing NAMkind human liver platform and expand liver toxicology capabilities. The new cross-species model is intended to help distinguish rat-specific liver toxicity from risks that may be relevant to humans.
The planned rat model would enable side-by-side comparison of rat and human liver responses, supporting decisions on whether to advance, modify, or further investigate drug candidates. According to VivoSim Labs, this addition could broaden the commercial utility of NAMkind by adding human-relevant context to widely used rat toxicology workflows.
