Ontology-driven and artificial intelligence-based repeated dose toxicity testing of chemicals for next generation risk assessment

Descrizione del progetto

Sviluppare il futuro dei test senza animali

Diversi prodotti usati nella vita quotidiana fanno uso di sostanze chimiche che richiedono test per garantire che non siano dannosi. Gli animali sono spesso utilizzati per testare gli effetti di queste sostanze chimiche su varie parti e organi del corpo, rendendo necessario un nuovo approccio ai test in linea con i principi moderni. Il progetto ONTOX, finanziato dall’UE, si propone di fornire un metodo all’avanguardia e senza il ricorso agli animali per testare le sostanze chimiche. Questo obiettivo sarà raggiunto attraverso un nuovo approccio che prevede gli effetti delle sostanze chimiche sul corpo usando l’IA combinata con dati e analisi medici multidisciplinari. Questo approccio potrebbe contribuire ad adottare rapidamente test senza animali, affermando allo stesso tempo l’Europa come leader nel campo della valutazione del rischio chimico.

Obiettivo

The vision of the ONTOX consortium is to provide a functional and sustainable solution for advancing human risk assessment of chemicals without the use of animals in line with the principles of 21st century toxicity testing and next generation risk assessment. Specifically, ONTOX will deliver a generic strategy to create innovative new approach methodologies (NAMs) in order to predict systemic repeated dose toxicity effects that, upon combination with tailored exposure assessment, will enable human risk assessment. This strategy can be applied to any type of chemical and systemic repeated dose toxicity effect. However, for proof-of-concept purposes, focus will be put on 6 specific NAMs addressing adversities in the liver (steatosis and cholestasis), kidneys (tubular necrosis and crystallopathy) and developing brain (neural tube closure and cognitive function defects) induced by a variety of chemicals, including from the pharmaceutical, cosmetics, food and biocide sectors. The 6 NAMs will each consist of a computational system based on cutting-edge artificial intelligence (AI) and will be primarily fed by available biological/mechanistic, toxicological/epidemiological, physico-chemical and kinetic data. Data will be consecutively integrated in physiological maps, quantitative adverse outcome pathway networks and ontology frameworks. Data gaps, as identified by AI, will be filled by targeted state-of-the-art in vitro and in silico testing. The 6 NAMs will be evaluated and applied in collaboration with industrial and regulatory stakeholders in order to maximise end-user acceptance and regulatory confidence. This is anticipated to expedite implementation in risk assessment practice and to facilitate commercialisation. ONTOX will have a deep and long-lasting impact at many levels, in particular by consolidating Europe’s world-leading position regarding the development, exploitation, regulation and application of animal-free methods for human risk assessment of chemicals.
