VivoSim (Nasdaq: VIVS) announced its first commercial sales of NAMkind™ liver and gastrointestinal toxicology screening and efficacy testing services in mainland China, secured via distributor Tekon with a leading Shanghai oncology biotech and a large Chengdu pharmaceutical company. These initial paid programs cover GI toxicology screening and GI efficacy profiling for oncology and other candidates and represent a meaningful share of VivoSim’s contracted revenue to date.
According to VivoSim, the addressable China market for liver and GI in vitro models and toxicology services is about $2 billion, growing at 10% CAGR. The NAMkind™ Liver model showed 91% predictive accuracy, 90% sensitivity and 95% specificity across 92 compounds, outperforming typical animal-model sensitivity. NAMkind™ services are now offered in the U.S., Europe and, with this launch, mainland China.
VivoSim (Nasdaq: VIVS) has priced a $4.0 million private placement with a single healthcare focused institutional investor, involving 4,705,883 shares of common stock (or equivalents) and accompanying warrants to purchase up to 4,705,883 shares, at an effective combined price of $0.85 per share and warrant.

VivoSim (Nasdaq: VIVS) presented new data on its AI-enabled NAMkind Liver and NAMkind GI platforms at ESTIV 2026. In a 92-compound clinical liver dataset, NAMkind Liver showed 91% accuracy, 90% sensitivity, 95% specificity, 99% precision, and >90% sensitivity versus 50–65% for traditional methods.
The models produced <5% liver-toxicity false positives versus >10% for some current approaches and were used to characterize toxicity for small molecules, TKIs and antibody-drug conjugates, including Trastuzumab Emtansine and Trastuzumab Deruxtecan.
VivoSim (Nasdaq: VIVS) announced an AI prediction tool, VitroSense™, trained on data from its NAMkind™ ileum and colon 3D human intestinal models to predict drug-induced diarrhea. VivoSim reports the model attained 96% predictive accuracy using a training set of dozens of compounds. The platform supports oral and IV dosing simulations and detected differential effects from antibody-drug conjugates (ADCs). NAMkind™ liver and small-intestine services are offered in the US, Europe, Korea, and China as the company scales capacity.
VivoSim (Nasdaq: VIVS) priced a best-efforts public offering of up to $4.0 million, with an Initial Closing funding of $3.0 million expected on April 1, 2026 and a conditional Second Closing of $1.0 million on day 30 following the Initial Closing.
