VivoSim Presents Best-in-Class Liver Toxicology Prediction Results at Digestive Disease Week Conference

SAN DIEGO, May 07, 2025 (GLOBE NEWSWIRE) — VivoSim Labs, Inc. (Nasdaq: VIVS) (the “Company”) announced today that its world-leading NAMkind platform for liver toxicology prediction, provided as a commercial service to pharma companies, was featured in an oral presentation at the Digestive Disease Week Conference (San Diego, CA, May 2-6, 2025) showing best-in-class predictive power against a set of test liver compounds.

VivoSim’s liver predictive power was shown to be 87.5% for a set of challenging liver toxicity cases – inclusive of classic cases of “liver tox misses” drugs with unforeseen liver toxicity found in clinical trials or drugs that were withdrawn from the market after liver toxicity issues emerged later. The platform identified correctly that 87.5% of the known liver-toxic drugs could be seen as liver toxic using NAMkind liver. This is known as the sensitivity of the platform, which at 87.5% is a world’s best. Importantly, the specificity was 100%, meaning that none of the compounds tested that are not liver toxic were incorrectly identified as having liver toxicity issues by the platform.

VivoSim’s NAMkind liver model is a physical organoid wet lab model of liver made using cells from human donors. VivoSim is also developing what it believes will be industry-best in silico predictions of liver tox. Artificial intelligence (AI) models in VivoSim’s NAMkind services suite will be trained on extensive set of proprietary, real-world data from organoid models made from human donor cells, giving much richer and more extensive information than is possible with data from human clinical trials.

VivoSim offers liver and intestinal toxicology insights using its premier new approach methodologies (NAM) models, following the announcement of FDA to phase out animal testing requirements in favor of these non-animal NAM methods. The FDA’s push to phase out animal models, announced on April 10, is expected to provide a powerful accelerant to VivoSim’s market adoption, disrupting a >$10B animal testing market with models that are more predictive and ethically sound.  

VivoSim has the capability to help transform the way drug development is done. By substantially reducing failures in clinical trials, the company believes it can help reduce the cost of development per approved drug by 50% across the industry. As a result of the inability to fully predict liver toxicity, a number of drugs today still fail clinical trials at late stages or are pulled from the market after launch due to unforeseen liver toxicity. VivoSim believes it will cut the incidence of such events by 50% or more.

VivoSim’s NAMkind intestine models can also deliver readouts on endpoints that are today not available to industry scientists selecting from many candidate drug molecules. As a result of the lack of such tools, a cancer patient might suffer nausea, vomiting, or intestinal problems, or a patient’s needed chemotherapy dose might be lower than it could be due to such conditions. VivoSim aims to provide transformative solutions for these challenges.

The FDA has laid out ambitious goals to phase out animal testing requirements as much as possible. VivoSim is launching to fill in the much-needed gap in commercially available solutions. The technology exists to achieve according to FDA Commissioner Marty A. Makary’s vision, which he expressed in March 2025 with the rollout of FDA’s push to move away from animal testing and towards NAM models. “By leveraging AI-based computational modeling, human organ model-based lab testing, and real-world human data, we can get safer treatments to patients faster and more reliably, while also reducing R&D costs and drug prices,” Makary noted. By leveraging AI-based computational modeling, human organ model-based lab testing, and. VivoSim is delivering on the promise of this technology, and will use its proprietary methods and cutting-edge capabilities for NAMkind models that displace use of animals and provide superior outcomes for its pharmaceutical customers, ultimately delivering for on the end goal of providing better solutions for patients.
