VivoSim to Debut Antibody Drug Conjugate Data, representing a major new market for NAMkind models, at Society of Toxicology Meeting in San Diego

SAN DIEGO, Feb. 11, 2026 (GLOBE NEWSWIRE) -- VivoSim Labs, Inc. (Nasdaq: VIVS) (the “Company” or “VivoSim”), a provider of next-generation New Approach Methodologies (NAMs) for preclinical safety, today announced it will attend the Society of Toxicology (“SOT”) meeting in San Diego, CA that takes place March 22-25 and present new data on its NAMkind™ liver and NAMkind™ Intestine model, including data on validating the models for use in predicting toxicity and side effect profiles of antibody drug conjugates (ADCs).

Considering the hundreds of ADCs in development across the globe, the potential for off target toxicity due to their common use in oncology to deliver cytotoxic payloads, and a lack of current available scientific solutions to separate anticancer activity from unwanted cytotoxicity, the use of NAMkind™ models becomes a powerful tool to use in conjunction with existing methods to select and improve the best ADC candidates for drug development.

VivoSim NAMkind™ models can reveal details of target engagement in organ tissues, premature linker cleavage, bystander effects and more in complex human cell models that replicate much of the target tissue biology in a controlled experimental setting.

Testing of approved ADC therapies in NAMkind™ models shows close correlation with clinical results

NAMkind™ models have now been tested against a wide set of marketed ADC molecules, showing close correlation with clinical results in terms of the toxic impact in the liver and side effect profile in the intestine (causing diarrhea). These results will be presented for the first time at SOT in San Diego.

“These ADC toxicity results show a close correlation to clinical safety outcomes,” said Amar Sethi, Chief Scientific Officer at VivoSim. “We think that our partners working with our testing models will be able to screen out toxicities during lead candidate optimization, resulting in greater success in the clinic at eliminating cancers using drugs with limited side effect profiles,” he continued.

“VivoSim’s scientific leadership in the field of human-relevant NAM models with results that translate to the clinic is bolstered by these new data,” said Keith Murphy, VivoSim’s Executive Chairman. “Our ability to demonstrate results that match known clinical results of cutting-edge drug modalities confirms that our 3D human cell models have a strong ability to faithfully reproduce the complex biology of human tissues.”

NAMKind™ liver and small intestine toxicology services are now available in US, Europe, and via local distributor engagement across Korea and China, with VivoSim continuing to scale capacity to support expanding global demand and urgent, real-world development needs.
