This paper explores what we can learn from the humanities and social sciences about how standards operate in and around science, in order to understand more about how ‘the gold standard’ can be shifted away from the use of animals in research and testing, and toward New Approach Methodologies (NAMs). These fields allow us to consider potential futures of NAMs as alternatives, replacements, or complements to animal use in testing and research. As we demonstrate, the questions that we pose and how they are framed are as important as the answers that result. Rather than asking how to ‘redefine the gold standard’, norms and expectations for NAMs must be actively debated and transparently defined. These considerations would be based, in part, on what has been learned in the past from non-human animal models and systems, but also use the norms within the fields from which the NAMs derive in light of the rich broader contexts within which they are being developed. As we argue, notions such as ‘a gold standard’ are limited and must be replaced by contextualised standards that depend on the scientific, sociocultural and other factors that contribute to our understanding of a particular method (new or otherwise) as ‘good’ for a particular purpose.

The Three Rs have become widely accepted and pursued, and are now the go-to framework that encourages the humane use of animals in science, where no other option is believed to exist. However, many people, including scientists, harbour varying degrees of concern about the value and impact of the Three Rs. This ranges from a continued adherence to the Three Rs principles in the belief that they have performed well, through a belief that there should be more emphasis (or indeed a sole focus) on replacement, to a view that the principles have hindered, rather than helped, a critical approach to animal research that should have resulted in replacement to a much greater extent. This critical review asks questions of the Three Rs and their implementation, and provides an overview of the current situation surrounding animal use in biomedical science (chiefly in research). It makes a case that it is time to move away from the Three Rs and that, while this happens, the principles need to be made more robust and enforced more efficiently. To expedite a shift from animal use in science, toward a much greater and quicker adoption of human-specific New Approach Methodologies (NAMs), some argue for a straightforward focus on the best available science.

The Korean Center for the Validation of Alternative Methods (KoCVAM), which promotes the Three Rs principles and the use of alternative methods in Korea, has been operating within the Toxicological Screening and Testing Division of the Ministry of Food and Drug Safety (MFDS) since 2009. KoCVAM has exchanged opinions and information on the development and validation of non-animal alternative test methods as part of the International Cooperation on Alternative Test Methods (ICATM), and provided input into draft OECD Test Guidelines (TGs). Several Korean laws (e.g. the Cosmetics Act) encourage the use of alternative test methods for chemical testing and assessment. To promote and support the use of alternative test methods in the country, KoCVAM has published information and provided training on the national guidelines, which are based on the OECD TGs. In addition, KoCVAM has held annual training workshops on alternative test methods, to help Korean research institutions (including GLP test facilities) to implement them. In addition, by helping to develop and validate alternative test methods that were adopted in OECD TG 442B, TG 492 and TG 439, KoCVAM has contributed to the enhanced competitiveness of Korean industry on the worldwide stage.

In the cosmetics sector, many products such as shampoos have a probability of accidental ocular exposure during their routine use. One very specific safety parameter is the residence time of the substance on the corneal surface, as prolonged exposure may cause injury. In this study, we developed a system that simulates corneal exposure to blinking and tear flow, for comparing the corneal clearance times of viscous detergent formulations. The Ex Vivo Eye Irritation Test (EVEIT), which uses corneal explants from discarded rabbit eyes from an abattoir, was used as the basis for the new system. To simulate blinking, we developed a silicone wiping membrane to regularly move across the corneal surface, under conditions of constant addition and aspiration of fluid, to mimic tear flow. Six shampoo formulations were tested and were shown to differ widely in their corneal clearance time. Three groups could be identified according to the observed clearance times (fast, intermediate and slow); the reference shampoo had the shortest clearance time of all tested formulations. With this new system, it is now possible to investigate an important physicochemical parameter, i.e. corneal clearance time, for the consideration of ocular safety during the development of novel cosmetic formulations.

The use of the brine shrimp Artemia salina (Leach) in acute toxicity assays has great potential due to its simplicity, low cost and reproducibility. In the current study, some of the variables that can influence the reliability of the assay in terms of test organism survival, were evaluated as part of its implementation in our laboratory. The quality and type of water used, the buffer components and other parameters (salinity, pH and dissolved oxygen level), were all evaluated for optimisation purposes. DMSO (dimethyl sulphoxide) was used as the test substance in the toxicity assay, to evaluate the concentration limits as a solvent in sample preparation. Regarding the buffer salinity, pH and dissolved oxygen level, we found that a 25% to 30% deviation from the standard values did not affect the survival of the nauplii (the first-instar larval stage) under assay conditions. In summary, we corroborate the potential use of this model for the prediction of the toxic potential of substances, to inform future testing strategies.

The Brazilian National Network of Alternative Methods (RENAMA), which is linked to the Ministry of Science, Technology and Innovation, is currently comprised of 51 laboratories from CROs, academia, industry and government. RENAMA’s aim is to develop and validate new approach methodologies (NAMs), as well as train researchers and disseminate information on their use — thus reducing Brazilian, and consequently Latin American, dependence on external technology. Moreover, it promotes the adoption of NAMs by educators and trained researchers, as well as the implementation of good laboratory practice (GLP) and the use of certified products. The RENAMA network started its activities in 2012, and was originally comprised of three central laboratories — the National Institute of Metrology, Quality and Technology (INMETRO); the National Institute of Quality Control in Health (INCQS); and the National Brazilian Biosciences Laboratory (LNBio) — and ten associated laboratories. In 2022, RENAMA celebrated its 10th anniversary, a milestone commemorated by the organisation of a meeting attended by different stakeholders, including the RENAMA-associated laboratories, academia, non-governmental organisations and industry. Ninety-six participants attended the meeting, held on 26 May 2022 in Balneário Camboriú, SC, Brazil, as part of the programme of the XXIII Brazilian Congress of Toxicology 2022. Significant moments of the RENAMA were remembered, and new goals and discussion themes were established. The lectures highlighted recent innovations in the toxicological sciences that have translated into the assessment of consumer product safety through the use of human-relevant NAMs instead of the use of existing animal-based approaches. The challenges and opportunities in accepting such practices for regulatory purposes were also presented and discussed.
