A goldmine to partly replace animal testing

Public databases of the toxic effects of chemicals that have been registered under the REACH directive have been sitting idle for too long. In an opinion piece, Thomas Hartung explains how the development of software by his team at the Bloomberg School of Public Health, at Johns Hopkins University, USA, helps make sense of the large volume of chemical database content. Now that they made such data machine readable, expectations are that it will soon be possible to provide open access to such public database. Ultimately, this could substantially decrease the number of animal tests. Indeed, the database makes it possible to do so-called read-across, allowing to infer toxicity of heaps of untested chemicals from existing data on chemicals of similar structure, which have already been tested.

Evidence-based safety science is nigh

To date, most toxicology tests have not been validated but they are still mandated by regulatory agencies. The question is to find suitable ways of modernising toxicology testing in the 21st century in a structured, consistent, transparent way. In this article, Thomas Hartung, Founder Evidence-Based Toxicology Collaboration (EBTC), at Johns Hopkins University Bloomberg School of Public Health, and colleagues, examine what remains to be done to address the mounting pressure exerted on industries and food and drug regulators worldwide to bring their decision-making process up-to-date with modern science. This calls for the use of a rigorous appraisal of the value of past studies under the umbrella of what has been dubbed evidence-based medicine (EBM), to be adapted in toxicology, to guarantee the safety of drug and consumer products.
