Available online: https://pub.norden.org/temanord2022-526/ New Approach Methodologies (NAMs) are an emerging tool in toxicology for performing chemical risk assessment. NAMs reduce animal testing while increasing robustness, throughput and providing a mechanistic understanding of chemical modes-of-actions, in accordance with the Next Generation Risk Assessment principles. The workshop’s objective was to increase risk assessors’ understanding of the data produced by NAMs and their ability to use it for regulatory actions under REACH and CLP. It aimed to highlight the main challenges for NAMs, discuss possible advancements in using NAMs, and increase knowledge and competence within the relevant Nordic authorities. It also served to facilitate discussions about the obstacles to implementing NAMs in regulatory processes, and to identify strategies (including omics approaches) for increasing their use in read-across and grouping processes.

Advances in molecular biology and toxicology are paving the way for major improvements in the evaluation of the hazards posed by the large number of chemicals found at low levels in the environment. The National Research Council was asked by the U.S. Environmental Protection Agency to review the state of the science and create a far-reaching vision for the future of toxicity testing. The book finds that developing, improving, and validating new laboratory tools based on recent scientific advances could significantly improve our ability to understand the hazards and risks posed by chemicals. This new knowledge would lead to much more informed environmental regulations and dramatically reduce the need for animal testing because the new tests would be based on human cells and cell components. Substantial scientific efforts and resources will be required to leverage these new technologies to realize the vision, but the result will be a more efficient, informative and less costly system for assessing the hazards posed by industrial chemicals and pesticides.

As part of its core mission, the U.S. Environmental Protection Agency (EPA) is tasked with assessing the hazards and risks to human health from exposure to pollutants. While some pollutants are well studied, there are little or no data on the potential health effects for many thousands of chemicals that can make their way into the environment, such as PFAS. EPA still relies on laboratory mammalian studies as the foundation of most human health risk assessments, which are limited by high costs, long timelines, and other concerns. New approach methods (NAMs) in toxicology, for example new in vivo and in vitro strategies and computational systems biology, offer opportunities to inform timely decision-making when no data are available from laboratory mammalian toxicity tests or epidemiological studies. NAMs may also help inform efforts to protect susceptible and vulnerable populations by characterizing subtle health perturbations, better encompassing genetic diversity, and accounting for nonchemical stressors. While the promise and need for NAMs is clear, many barriers to their use remain. This report aims to bridge the gap between the potential of NAMs and their practical application in human health risk assessment. Building Confidence in New Evidence Streams for Human Health Risk Assessment draws lessons learned from laboratory mammalian toxicity tests to help inform approaches for building scientific confidence in NAMs and for incorporating such data into risk assessment and decision-making. Overall, the report recommendations aim to ensure a seamless handoff from the evaluation of NAM-based testing strategies in the laboratory to the incorporation of NAM data into modern, systematic-review-based risk assessments.

Toxicity testing in laboratory animals provides much of the information used by the Environmental Protection Agency (EPA) to assess the hazards and risks associated with exposure to environmental agents that might harm public health or the environment. The data are used to establish maximum acceptable concentrations of environmental agents in drinking water, set permissible limits of exposure of workers, define labeling requirements, establish tolerances for pesticides residues on food, and set other kinds of limits on the basis of risk assessment. Because the number of regulations that require toxicity testing is growing, EPA called for a comprehensive review of established and emerging toxicity-testing methods and strategies. This interim report reviews current toxicity-testing methods and strategies and near-term improvements in toxicity-testing approaches proposed by EPA and others. It identifies several recurring themes and questions in the various reports reviewed. The final report will present a long-range vision and strategic plan to advance the practices of toxicity testing and human health assessment of environmental contaminants.

The US Department of Defense (DOD) is faced with an overwhelming task in evaluating chemicals that could potentially pose a threat to its deployed personnel. There are over 84,000 registered chemicals, and testing them with traditional toxicity-testing methods is not feasible in terms of time or money. In recent years, there has been a concerted effort to develop new approaches to toxicity testing that incorporate advances in systems biology, toxicogenomics, bioinformatics, and computational toxicology. Given the advances, DOD asked the National Research Council to determine how DOD could use modern approaches for predicting chemical toxicity in its efforts to prevent debilitating, acute exposures to deployed personnel. This report provides an overall conceptual approach that DOD could use to develop a predictive toxicology system. Application of Modern Toxicology Approaches for Predicting Acute Toxicity for Chemical Defense reviews the current state of computational and high-throughput approaches for predicting acute toxicity and suggests methods for integrating data and predictions. This report concludes with lessons learned from current high-throughput screening programs and suggests some initial steps for DOD investment.
