We initiated the Predictive Toxicology Challenge (PTC) to stimulate the dev
elopment of advanced SAR techniques for predictive toxicology models. The g
oal of this challenge is to predict the rodent carcinogenicity of new compo
unds based on the experimental results of the US National Toxicology Progra
m (NTP). Submissions will be evaluated on quantitative and qualitative scal
es to select the most predictive models and those with the highest toxicolo
gical relevance.
