Traditional Caco-2 monolayer models fall short when predicting human-relevant intestinal toxicity, particularly for inflammation-driven responses like diarrhea. VivoSim’s NAMkind™ Intestine Model offers a breakthrough solution—combining physiological relevance with predictive power. Built on a 3D Transwell platform, the NAMkind™ Intestine Model incorporates both epithelial and stromal cells, enabling a more accurate recreation of native intestinal tissue and function. This advanced model allows for best-in-class diarrhea and inflammatory toxicity prediction, capturing key cytokine signaling that traditional models miss.

With integrated assays to measure epithelial barrier integrity (TEER) and differentiate between the viability of epithelial and stromal compartments, the NAMkind™ Intestine Model delivers a detailed and dynamic view of gut health under drug exposure, empowering researchers to make safer, more informed decisions earlier in development.

FDA Alignment

Aligned with FDA’s New Approach Methodology (NAM) Framework
Our GI toxicity services are fully aligned with the FDA’s initiative to advance non-animal testing methods. NAMkind™ models are benchmarked against FDA and NIH reference compounds and adhere to performance criteria outlined in the Tox21 and NCATS collaborative frameworks for translational toxicology.

Our goal: Provide human-relevant intestinal data that meets the rigor of FDA expectations — supporting safer and faster drug development decisions.

VivoSim partners with pharmaceutical, biotech, and AI-driven drug discovery teams to modernize preclinical safety testing. By merging human primary cell biology, AI-powered analytics, and FDA-aligned NAM frameworks, we enable a more predictive, ethical, and efficient path to development
