1. What Is the Early Toxicity Testing Market?
The Early Toxicity Testing Market covers in vitro, in silico, and organ-on-chip assays predicting drug toxicity at lead optimisation and preclinical stage to reduce late-stage attrition and animal testing burden. Early toxicity testing encompasses hepatotoxicity assay, cardiotoxicity hERG assay, organ-on-chip microphysiological system, and AI ADMET prediction. Market dynamics reflect FDA Modernisation Act 2.0 creating alternative animal pathway, organ-on-chip maturing to GLP assay, and AI ADMET improving hit-to-lead toxicity triage.
