The use of Integrated Testing Strategies (ITS) permits the combination of diverse types of chemical and toxicological data for the purposes of hazard identification and characterisation. In November 2008, the European Partnership for Alternative Approaches to Animal Testing (EPAA), together with the European Centre for the Validation of Alternative Methods(More)
Neurotoxicity aims to understand how xenobiotics interfere with the function of the nervous system and to unravel their mechanisms of action. Neuronal activity is the primary functional output of the nervous system and deviations from its resting level may indicate toxicity. Consequently, the monitoring of electrophysiological activity in complex cell(More)
The use of Integrated Testing Strategies (ITS) in toxicological hazard identification and characterisation is becoming increasingly common as a method for enabling the integration of diverse types of toxicology data. At present, there are no existing procedures and guidelines for the construction and validation of ITS, so a joint EPAA WG5-ECVAM workshop was(More)
The development of alternative empirical (testing) and non-empirical (non-testing) methods to traditional toxicological tests for complex human health effects is a tremendous task. Toxicants may potentially interfere with a vast number of physiological mechanisms thereby causing disturbances on various levels of complexity of human physiology. Only a(More)
To support Evidence-based toxicology (EBT)-related activities and facilitate the practical implementation of EBT, European Centre for the Validation of Alternative Methods (ECVAM) has developed a concept for a web-based “portal to EBT,” an internet platform to search/retrieve topics related to evidencebased approaches such as events, other relevant(More)
The European Cosmetics Directive and REACH have accelerated the need for alternative tests. Especially the animal testing ban of cosmetic ingredients from 2009 strongly impacts on the timely delivery of relevant methods. ECVAM's key area "topical toxicity" focuses on skin and eye irritation/corrosion, phototoxicity and percutaneous absorption. Regulatory(More)
Provisions of Regulation No 1223/2009 on cosmetic products require that the European Commission reports on a yearly basis to the European Parliament and Council on the progress made in the development, validation and regulatory acceptance of alternative methods and on the compliance with the deadlines of the animal testing and marketing bans.

Alternative test methods often use prediction models (PMs) for converting endpoint measurements into predictions. Two PMs are used for the skin corrosion tests (SCTs) of the OECD Test Guideline No. 431 (TG 431). One is specific to EpiSkin™ test method, whereas EpiDerm™, SkinEthic™ RHE and epiCS® share a common PM. These methods are based on reconstructed(More)
