Predicting Gastrointestinal Toxicity
GI toxicity is a leading cause of clinical adverse events, yet most preclinical models consistently fail to flag it. The MIMETAS OrganoReady® Colon Organoid gives you a human-relevant readout you can act on — as a ready-to-use plate you run yourself, or as a fully outsourced and standardized OrganoServices study.
Conventional Models
Fall Short
Animal studies and standard 2D cell lines don’t replicate the polarized, perfused epithelium of the human gut. The result: GI liabilities that pass preclinical screening only to surface in Phase I or later.
Predicting GI Tox with the OrganoReady® Colon Organoid
Human stem cell-derived, perfused: a polarized tubular epithelium with intact transport, metabolism, and barrier function.




Tested Against
Clinical Outcomes
A retrospective study with 28 reference compounds — 14 clinically characterized GI-toxic and 14 non-toxic drugs — characterized the model’s predictive performance against the gold-standard Caco-2 Transwell assay (TEER & ATP).

Callout: colchicine was flagged at submicromolar concentrations, consistent with its clinical GI toxicity profile — representative of the 28-compound reference panel.

What Our Customers Say
At Bayer, we’ve integrated the OrganoReady® Colon Organoid Model with the OrganoTEER® system into our routine toxicity screening, because it delivers more physiologically relevant and reproducible data than conventional intestinal models. Using Afatinib as a positive control, we consistently see stable IC₅₀ values, confirming the reliability of the model and the precision of the OrganoTEER® readout.
We used the OrganoReady® Colon Organoid to assess potential human gastrointestinal toxicity, and even as a first-time user the workflow was straightforward from receipt to data acquisition. Positive controls performed as expected, and the data quality supported interpretation of mechanisms and relative compound effects. Reproducibility across plates was strong, and with plate-level design we minimized variability and obtained the needed insights with a small sample size.
