Alternative methods for regulatory toxicology – a state-of-the-art review

This state-of-the art review is based on the final report of a project carried out by the European Commission’s Joint Research Centre (JRC) for the European Chemicals Agency (ECHA). The aim of the project was to review the state of the science of non-standard methods that are available for assessing the toxicological and ecotoxicological properties of chemicals. Non-standard methods refer to alternatives to animal experiments, such as in vitro tests and computational models, as well as animal methods that are not covered by current regulatory guidelines. This report therefore reviews the current scientific status of non-standard methods for a range of human health and ecotoxicological endpoints, and provides a commentary on the mechanistic basis and regulatory applicability of these methods. For completeness, and to provide context, currently accepted (standard) methods are also summarised. In particular, the following human health endpoints are covered: a) skin irritation and corrosion; b) serious eye damage and eye irritation; c) skin sensitisation; d) acute systemic toxicity; e) repeat dose toxicity; f) genotoxicity and mutagenicity; g) carcinogenicity; h) reproductive toxicity (including effects on development and fertility); i) endocrine disruption relevant to human health; and j) toxicokinetics. In relation to ecotoxicological endpoints, the report focuses on non-standard methods for acute and chronic fish toxicity. While specific reference is made to the information needs of REACH, the Biocidal Products Regulation and the Classification, Labelling and Packaging Regulation, this review is also expected to be informative in relation to the possible use of alternative and non-standard methods in other sectors, such as cosmetics and plant protection products.JRC.I.5-Systems Toxicolog

EURL ECVAM Status Report on the Development, Validation and Regulatory Acceptance of Alternative Methods and Approaches (2016)

Replacement, Reduction and Refinement of animal testing is anchored in EU legislation. Alternative non-animal approaches facilitate a shift away from animal testing. Cell-based methods and computational technologies are integrated to translate molecular mechanistic understanding of toxicity into safety testing strategies.JRC.F.3-Chemicals Safety and Alternative Method

EURL ECVAM Status Report on the Development, Validation and Regulatory Acceptance of Alternative Methods and Approaches (2019)

The European Union Reference Laboratory for alternatives to animal testing (EURL ECVAM) is an integral part of the European Commision's Joint Research Centre. The EURL ECVAM status report informs about research and development activities, test method submissions, validation and peer reviews, activities that promote the regulatory acceptance and international adoption of alternative methods and approaches and their dissemination. Replacement, reduction and refinement of animal testing (Three Rs) in basic, applied and translational research, as well as for regulatory purposes is anchored in EU legislation. Innovative technologies (e.g., computational models, in vitro methods, organ-on-chip devices) are developed, evaluated and integrated in assessment strategies for chemicals and products safety testing in order to preserve a high level of protection for human health and the environment. Important activities to promote the development and use of alternative methods and approaches are also pursued in the areas of basic and applied research as well as for education purposes.JRC.F.3-Chemicals Safety and Alternative Method
