Bridging Across Methods in the Biosciences

Cross-disciplinary research is essential if science is to properly address societal needs. In spite of several policy initiatives to foster such research across sectors, there is still a high level of compartmentalisation in the biosciences. The European Commission is preparing for a Missions based science and innovation strategy in which it will be important to consider how the goal of meaningful cross-disciplinarity can be achieved. This report aims to raise the question of cross-disciplinarity again, and to suggest specific actions to further the understanding, achievement and evaluation of cross-disciplinarity in the biosciences.JRC.F.3-Chemicals Safety and Alternative Method

Accelerating progress in the Replacement, Reduction and Refinement of animal testing through better knowledge sharing

In the context of the European Commission's Communication published in response to the European Citizens' Initiative "Stop Vivisection", Action 1 aimed to conduct an assessment of current technologies, information sources and networks from all relevant sectors with potential impact on the advancement of the refinement, reduction and replacement of animals used for scientific purposes (the "Three Rs"). The main objective of this study is to map knowledge sources relevant to the Three Rs, to examine how knowledge is being shared, and to identify possible gaps and opportunities to enhance knowledge sharing. An inventory of knowledge sources (KS) potentially relevant to the Three Rs used in the area of life sciences has been compiled which should be viewed as a snapshot of the current status of knowledge sources available (the supply), and as a starting point for further analysis of knowledge sharing strategies. A public survey was also conducted to complement this study (supply versus demand), and to inform on how to proceed effectively with any knowledge management strategy. The survey has revealed that many involved in this area consider that whilst access to relevant knowledge sources is adequate, there is a need for better coordination of the sources, as well as for the communication of information. Opportunities for face-to-face exchanges are highly valued and there is a firm call for more developments in education and training at professional, university and secondary school levels.JRC.F.3-Chemicals Safety and Alternative Method

Knowledge Management for Policy: Stocktaking of one year of JRC activities

Improving knowledge management and collaborative working is a priority for overcoming silos mentalities and connecting synergies between portfolios, as envisaged in the Commission Communication C(2016)6626. In its 2030 Strategy, the JRC took up this challenge by 1) introducing a horizontal ‘knowledge management’ layer in the organigram, to mobilise scientific competences from different Directorates around the Commission’s policy goals 2) championing the implementation of new collaboration practices and platforms as well as the development of a knowledge management professionalisation programme; 3) starting to transform itself from a traditional research-producing organisation into a world-leading manager of knowledge for EU policy-making. One year after the reorganisation carried out on the 1st of July 2016 to align the JRC organigram with the new strategy, this report reviews the progress made and describes the main achievements.JRC.H-Knowledge Management (Ispra

The European Chemicals Bureau: an Overview of 15 Years Experience in EU Chemicals Legislation

From its creation in 1993, the European Chemicals Bureau (ECB) has played a vital role in the conception, development, implementation and monitoring of European Union (EU) legislation on chemicals and in contributing to the European Commission¿s participation in international chemicals programmes. The ECB has housed much of the European Commission¿s experience, capacity and historical memory in chemical risk assessment and safe chemical management. The contribution of ECB to the drafting, development and implementation of the REACH regulation has been an important one. The provision of scientific/technical expertise to the start-up phase of the newly born European Chemicals Agency (ECHA) has been essential for a swift and effective implementation of REACH. The ECB has contributed to that effort not only by selecting, recruiting and training ECHA staff but also by seconding part of its own key staff to the agency. And finally, during 2008 the ECB is completing the hand-over files and transmitting them to the ECHA, which is taking over responsibility for the operational implementation of EU legislation on chemicals.JRC.I-Institute for Health and Consumer Protection (Ispra

EURL ECVAM Status Report on the Development, Validation and Regulatory Acceptance of Alternative Methods and Approaches (2013-April 2014)

The EURL ECVAM status report provides an update on the progress made in the development, validation and regulatory acceptance of alternative methods and approaches since the last report published in April 2013. It is informing on ongoing research and development activities, validation studies, peer reviews, recommendations, strategies and international acceptance of alternative methods and approaches. R&D activities are ongoing for the complex endpoints where the toxicological processes and the mechanistic understanding have not been sufficiently elucidated yet and for which 3Rs solutions are more difficult to find. On the other hand, good progress In the validation and regulatory acceptance is made in areas where non-animal alternative methods have been developed and validated and where the focus lies in an intelligent combination/ integration of the various non-animal approaches.JRC.I.5-Systems Toxicolog

diXa: a data infrastructure for chemical safety assessment

Motivation: The field of toxicogenomics (the application of ‘-omics' technologies to risk assessment of compound toxicities) has expanded in the last decade, partly driven by new legislation, aimed at reducing animal testing in chemical risk assessment but mainly as a result of a paradigm change in toxicology towards the use and integration of genome wide data. Many research groups worldwide have generated large amounts of such toxicogenomics data. However, there is no centralized repository for archiving and making these data and associated tools for their analysis easily available. Results: The Data Infrastructure for Chemical Safety Assessment (diXa) is a robust and sustainable infrastructure storing toxicogenomics data. A central data warehouse is connected to a portal with links to chemical information and molecular and phenotype data. diXa is publicly available through a user-friendly web interface. New data can be readily deposited into diXa using guidelines and templates available online. Analysis descriptions and tools for interrogating the data are available via the diXa portal.

EURL ECVAM Status Report on the Development, Validation and Regulatory Acceptance of Alternative Methods and Approaches (2015)

The EURL ECVAM status report provides an update on the progress made in the development, validation and regulatory acceptance of alternative methods and approaches and their dissemination since the last report published in June 2014. It is informing on ongoing research and development activities, validation studies, peer reviews, recommendations, strategies and regulatory/international acceptance of alternative methods and approaches and dissemination activities. R&D activities within large European or International consortia continued in toxicity areas where 3Rs solutions are more difficult to find due to the underlying complexity of the area. On the other hand, toxicity areas where promising non-animal approaches have been developed, their validation and regulatory acceptance/international adoption could be progressed. Particular emphasis was given to the best and most intelligent combination and integration of these different non-animal approaches to ultimately obtain the required information without resorting to animal testing.JRC.I.5-Systems Toxicolog

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

Application of AOPs to assist regulatory assessment of chemical risks - Case studies, needs and recommendations

While human regulatory risk assessment (RA) still largely relies on animal studies, new approach methodologies (NAMs) based on in vitro, in silico or non-mammalian alternative models are increasingly used to evaluate chemical hazards. Moreover, human epidemiological studies with biomarkers of effect (BoE) also play an invaluable role in identifying health effects associated with chemical exposures. To move towards the next generation risk assessment (NGRA), it is therefore crucial to establish bridges between NAMs and standard approaches, and to establish processes for increasing mechanistically-based biological plausibility in human studies. The Adverse Outcome Pathway (AOP) framework constitutes an important tool to address these needs but, despite a significant increase in knowledge and awareness, the use of AOPs in chemical RA remains limited. The objective of this paper is to address issues related to using AOPs in a regulatory context from various perspectives as it was discussed in a workshop organized within the European Union partnerships HBM4EU and PARC in spring 2022. The paper presents examples where the AOP framework has been proven useful for the human RA process, particularly in hazard prioritization and characterization, in integrated approaches to testing and assessment (IATA), and in the identification and validation of BoE in epidemiological studies. Nevertheless, several limitations were identified that hinder the optimal usability and acceptance of AOPs by the regulatory community including the lack of quantitative information on response-response relationships and of efficient ways to map chemical data (exposure and toxicity) onto AOPs. The paper summarizes suggestions, ongoing initiatives and third-party tools that may help to overcome these obstacles and thus assure better implementation of AOPs in the NGRA
