FDA has announced a plan to replace animal testing in the development of monoclonal antibody therapies and other drugs with more effective, human-relevant methods. The approach is outlined in FDA’s “Roadmap to Reducing Animal Testing in Preclinical Safety Studies” An April 10 press release provides an overview of the approach.

FDA will reduce, refine, or potentially replace animal testing using a range of approaches, including artificial intelligence-based computational models of toxicity and cell lines and organoid toxicity testing in a laboratory setting. Implementation of the regimen will begin immediately for investigational new drug applications, where inclusion of NAM data is encouraged. To make determinations of efficacy, the agency will begin using pre-existing, real-world safety data from other countries with comparable regulatory standards where the drug has already been studied in humans.

The roadmap describes how FDA will collaborate with ICCVAM to coordinate validation efforts and leverage data and expertise available in other government agencies. The roadmap specifically mentions the Complement Animal Research in Experimentation (Complement-ARIE) project as an avenue through which development of relevant NAMs could be supported. Complement-ARIE is an NIH Common Fund project focused on accelerating the development, standardization, validation, and use of human-based NAMs.

Scientists who have published papers within the last three years describing original work that could impact the use of animals in research are encouraged to apply for the International 3Rs Prize. This prize is administered by the United Kingdom NC3Rs. It consists of a £28k prize grant and a £2k personal award and is partially funded by GlaxoSmithKline. The primary research must have been published in a peer-reviewed journal between September 2021 and September 2024. Papers that were in press by September 1, 2024, will also be considered. Awardees may be the principal investigator, research lead, or any other author on the paper, and researchers all over the world are eligible to apply. The application deadline is May 1.

Save the date – October 21-25 – for the 14th ASCCT Annual Meeting. The meeting will be held at the Institute of In Vitro Sciences, Gaithersburg, MD, which is about 20 miles outside of Washington, DC. The meeting will feature multiple oral and poster presentation sessions, continuing education courses, and a practical workshop, and offer networking opportunities. Session and continuing education proposals are due April 25, abstract submissions open May 15, and abstracts and travel award applications are due July 30.

EPA will provide training on its Sequence Alignment to Predict Across Species Susceptibility (SeqAPASS) tool on Thursday, May 1. The training is free but registration is required to attend.

There is a growing demand for predictive approaches to maximize the use of existing data to develop environmental risk assessments due to decreasing testing resources available, international interest in reducing animal use, and increasing demand to evaluate chemicals in a timelier manner. SeqAPASS is a fast, online screening tool that allows researchers and regulators to extrapolate toxicity information across species. The tool uses publicly available protein sequence and structure information to examine species similarities and differences to better understand the effects of chemicals on non-target species.

The training is divided into two parts to accommodate a variety of interests and schedules.

• Session 1 (11:00 a.m.-12:30 p.m. EDT) will feature:
  • An introduction and overview lecture of SeqAPASS’s purpose and scope.
  • A demonstration of SeqAPASS’s interface, features, and functionality.
  • A question-and-answer session.
• Session 2 (12:45 – 2:00 p.m. EDT) will divide attendees into breakout groups that will work through a SeqAPASS case study. A group moderator will be available to provide guidance, walk through workflow steps, and answer questions.

SOT recognized the accomplishments of NICEATM Director Nicole Kleinstreuer and two NICEATM student researchers with awards presented during their 2025 annual meeting. A full list of 2025 SOT award recipients is available at https://www.toxicology.org/awards/sot/recipients2025.asp.

Kleinstreuer received the 2025 SOT Enhancement of Animal Welfare Award. This award recognizes an SOT member for contributions made to the advancement of toxicological science through the development and application of methods that replace, refine, or reduce the need for experimental animals. For the 2025 award, SOT specifically recognized Kleinstreuer for her leadership and management of NICEATM and ICCVAM and the significant effects that these efforts have had on the replacement, refinement, and reduction in the use of experimental animals.

Kleinstreuer came to NICEATM following graduate study at the University of Canterbury in Christchurch, New Zealand, and a postdoctoral fellowship at the U.S. Environmental Protection Agency (EPA) National Center for Computational Toxicology. She has been NICEATM Director since 2020 and leads a 25-person group responsible for the development and validation of various new approach methodologies (NAMs) supporting replacement, reduction, and refinement of animal use. An internationally recognized driver in the NAMs space, Kleinstreuer played a lead role in developing the first internationally harmonized guideline on defined approaches to skin sensitization that serves as a full replacement for a regulatory-required animal test. She also has co-led multiple efforts to develop and validate nonanimal methods for endocrine disruption screening that have been accepted by EPA as alternatives to rodent bioassays and as sources of information in weight-of-evidence analyses and priority setting. Most recently, she conceptualized and led strategic planning for a large National Institutes of Health Common Fund program to Complement Animal Research in Experimentation (Complement-ARIE) which will dedicate hundreds of millions of dollars to fund the development of human-biology based integrated NAMs.

NICEATM was also honored for the work of two student researchers who received 2025 SOT Undergraduate Research Awards. These awards recognized outstanding undergraduates who presented research at the SOT Annual Meeting. The goal of these awards is to foster interest in graduate studies in the field of toxicology.

NIEHS and NICEATM have entered into a public-private partnership with the International Collaboration on Cosmetics Safety (ICCS) to conduct a landscape analysis on the current state of non-animal, human-relevant methods and approaches for assessing systemic toxicity. The analysis will focus on describing existing efforts, and will highlight gaps, challenges, and opportunities associated with human-relevant models of systemic toxicity. The intent is to provide sufficient coverage of the landscape both to address pragmatic near-term needs and to shape the future of how safety assessments are performed. This work will use a generative artificial intelligence approach to drastically decrease the time and improve efficiency of completing the analysis, which is expected to be completed in Spring 2025. More information about the project is available on the ICCS webpage.

The Coalition to Illuminate and Address Animal Methods Bias (COLAAB) presents “Addressing Reviewers’ Preference for Animal-Based Methods” in a webinar on Wednesday, December 18 from 1:00-2:30 p.m. ET. Registration and webinar information are already available.

COLAAB is an international collaboration of researchers and advocates gathering information evidence of animal methods bias and mitigating its detrimental effects on biomedical research. Animal methods bias is the preference for animal-based research methods or the lack of expertise to adequately evaluate nonanimal methods. A recent COLAAB study found that half of researchers surveyed had been asked by reviewers to add an animal experiment to their otherwise animal-free study. These requests and other forms of animal methods bias can affect the quality or fairness of nonanimal research assessments, including peer reviews of manuscripts and grant applications, potentially causing delays in publication, lower-impact papers, or rejected grants. In this webinar, Catherine Krebs of the Physicians Committee for Responsible Medicine will provide an overview of animal methods bias and ongoing work of the COLAAB, including the latest evidence and a new online tool authors can use to help prevent and address animal methods bias when publishing studies.

The Animal Protection Commissioner of Berlin, the Johns Hopkins University Center for Alternatives to Animal Testing (CAAT), and the Physicians Committee for Responsible Medicine (PCRM) are launching a new workshop series focused on animal-free NAMs in biomedical research. The first two-hour online workshop will take place on Tuesday, November 19, at 10 a.m. ET (4 p.m. CET) via Zoom. Registration and more information are available.

The November 19 event will feature two presentations:

• Jarrod Bailey, PCRM, will explain how human-focused research provides greater clinical benefits. Due to significant biological differences, animal models often fail to translate effectively to human biology, leading to poor clinical outcomes in areas like drug testing and research on diseases such as Alzheimer’s, Parkinson’s, HIV/AIDS, and cancer.
• Angela Hvitved, Alternatives Research & Development Foundation, will discuss writing successful grant applications for funding non-animal methods research. She will address two key topics, funding sources and writing competitive applications.

Presentation slides and video are available from the August 21-22 ICCVAM Method Developers Forum, which focused on NAMs for carcinogenicity testing. The webinar featured presentations by selected method developers describing their methods and proposing how they may be useful for regulatory and/or industry stakeholders. Stakeholders representing potential government and industry users of the NAMs or the data they generate also participated in the webinar. Slides, video, and more information about the webinar are available.

The next ICCVAM Method Developers Forum will focus on NAMs for cardiovascular toxicity testing. Development of videos summarizing regulatory and industry stakeholders’ information requirements and/or decision frameworks relevant to cardiovascular toxicity is in progress, with a webinar planned for spring 2025. More information will be posted on the website mentioned above as it becomes available.

The U.S. Environmental Protection Agency (EPA) released a detailed review of major environmental statutes that summarizes which EPA laws or regulations require vertebrate animal testing, such as laboratory testing done on rats, mice, or rabbits. The report concludes that many statutes and regulations guiding EPA’s authority are broadly written and do not preclude the use of scientific information from NAMs, which are defined as any technology, methodology, approach, or combination that can provide information on chemical hazard and risk assessment to avoid the use of animal testing.

The U.S. Environmental Protection Agency (EPA) released a detailed review of major environmental statutes that summarizes which EPA laws or regulations require vertebrate animal testing, such as laboratory testing done on rats, mice, or rabbits. The report concludes that many statutes and regulations guiding EPA’s authority are broadly written and do not preclude the use of scientific information from NAMs, which are defined as any technology, methodology, approach, or combination that can provide information on chemical hazard and risk assessment to avoid the use of animal testing.

This report is a deliverable in EPA’s NAMs Work Plan, which was originally released in June 2020 and updated in November 2021. The Work Plan outlines the Agency’s strategies and objectives for increasing the rigor and sophistication of Agency assessments while reducing the reliance on vertebrate animals to test chemicals in regulatory, compliance, enforcement, and research activities through the use of NAMs. The assessments will remain fully protective of human health and the environment. The first objective in the Work Plan was to evaluate regulatory flexibility for accommodating NAMs, and the report accomplishes that objective.

The National Institutes of Health (NIH) Common Fund, along with its partner NIH Institutes, Centers, and Offices has published two Notices of Funding Opportunity (NOFOs) to support the Completement Animal Research in Experimentation (Complement-ARIE) Program. Complement-ARIE will accelerate the development, standardization, validation, and use of human-based New Approach Methodologies (NAMs).

The U.S. Environmental Protection Agency (EPA) Office of Research and Development, in conjunction with NICEATM, is convening a workshop to facilitate discussion of probabilistic methods in human health risk assessment. This workshop will provide examples of the application of probabilistic methods in chemical risk assessments, highlight ongoing research, and discuss the needs and challenges for the regular use of these methods. The workshop will be held in person at EPA in Research Triangle Park, NC and also webcast. In-person attendees should register by Tuesday, September 24.

Those planning to attend in person are invited to submit abstracts for a poster session. Abstracts should describe projects or activities relevant to workshop agenda topics. Abstracts will be accepted until Friday, September 13 or until 40 abstracts are received. Organizers will contact submitters to confirm poster acceptance and provide logistical details about the presentation.

The National Academies of Sciences, Engineering, and Medicine recently recommended consideration of how and when traditional deterministic approaches for human health risk assessment (i.e., toxicity value point estimates) can be transitioned towards probabilistic methods for deriving risk-specific doses. This workshop will highlight past examples where probabilistic methods were implemented to derive chemical-specific toxicity values, provide insight into the current state of the research surrounding probabilistic methods in chemical risk assessments, and discuss the future directions for implementing these probabilistic methods in human health assessments. The agenda will feature sessions on four subtopics:

• Probabilistic exposure
• Toxicokinetics
• Benchmark dose modeling
• Toxicity value determination

Throughout these sessions interdisciplinary panels comprising subject matter experts from government, industry, academia, and nongovernmental organizations will conduct panel discussions to evaluate the proposed methods and provide suggestions for how the transition might be implemented. Workshop participants should gain a greater understanding of probabilistic methods within the context of human health assessments and learn how these methods may ultimately be implemented.

The U.S. Environmental Protection Agency (EPA) conducted a value of information (VOI) analysis to weigh the public health and economic trade-offs associated with the timeliness, uncertainty, and costs of conducting the EPA Transcriptomics Assessment Product compared to traditional human health assessment processes. EPA’s VOI framework and a report on a case study applying the framework are now available.

Fewer than a quarter of the tens of thousands of chemicals in commerce--as well as those found in the environment, various waste streams, and the human body--have traditional toxicity or epidemiological data that can inform human health risk assessments. VOI analysis is a systematic approach to determine the “value of information” in economic terms. It allows comparison of “what we already know” and “what we will know” to determine which data generation methodologies are most valuable for decision-making. While the potential application of value-of-information analysis for toxicology has been discussed for a number of years, practical applications of such an analysis in toxicology to real-world problems are lacking.

A novel feature of the EPA framework was the inclusion of a time dimension that permits incorporation of the cost of delay in incorporating additional information. The case study described in the report applied this framework to compare a short-term in vivo transcriptomic assay approach to developing protective reference doses with the traditional chronic rodent bioassay and human health assessment process. A panel of the EPA Board of Scientific Counselors was convened to assess the scientific rigor of this case study and the resulting conclusions.

The United Kingdom National Centre for the 3Rs (NC3Rs) is offering £4M in grants to develop infrastructure to accelerate the use of approaches that replace the use of animals in research and testing. This funding call is exclusively for non-research proposals that will increase the capacity and capabilities of the UK research base to use non-animal methods. Funding could be used to purchase equipment and associated consumables, develop platforms for data sharing, fund access to demonstrator labs to facilitate scale-up and training, or create hubs and networks to facilitate the collation and distribution of resources that support the use of non-animal methods. More information is available; apply by July 30th.

NC3Rs is also offering £1M to support projects seeking to characterize and validate the use of non-animal derived reagents and products for use in in vitro research. Despite their documented benefits, the widespread use of animal-free reagents and products in in vitro research has been hindered by the lack of dedicated support for the characterization and validation studies that are required to build the experience and confidence necessary to shift practice. This funding call is meant to address this need with the aim to build further confidence in these alternative approaches and demonstrate that they are fit-for-purpose. More information is available; apply by July 30th.

As a follow-up to the publication of the report on Validation, Qualification, and Regulatory Acceptance of New Approach Methodologies, ICCVAM and NICEATM will host a series of Method Developers’ Forums (MDFs), each focused on a specific endpoint/toxicity, that provide an opportunity for NAMs developers to discuss their methods and regulatory issues with relevant stakeholders.

This will be an interactive forum at which method developers will have an opportunity to describe how the NAM is appropriate for addressing the carcinogenicity information requirements of one or more federal agencies and answer questions from agency representatives about the NAM. Developers will be selected to participate in the forum on the basis of proposals submitted to the MDF steering committee, which includes scientists from federal research and regulatory agencies with an interest in this endpoint.

Submit proposals by Friday, July 26. Your proposal should be in the form of the presentation you plan to give at the forum. It should provide an overview of the NAM and its relevance to carcinogenicity testing. Provide enough technical detail and data on the performance of the NAM for regulatory and industry stakeholders to understand how your NAM may meet their needs. Proposals should be in the form of a PowerPoint presentation exported to PDF format. The resulting file should be no larger than 100 MB. Details on how to prepare proposals and resources available on this page include:

• Instructions for submitting your proposal and important dates.
• Video presentations from federal agencies explaining their information requirements and decision frameworks for carcinogenicity testing.
• Guidance for developing proposals, including specific questions that should be addressed in your proposal.
• A template you may use for developing your PowerPoint presentation.

The next webinar in the EPIC series on the use of new approach methodologies (NAMs) in risk assessment will cover “The CATMoS model for acute oral toxicity and evaluation of its potential use in a regulatory context for pesticide hazard and risk assessment.” The webinar will be held on Wednesday, August 28 at 11:00 a.m. EDT.

The webinar will feature presentations by NICEATM scientist Kamel Mansouri, National Institute of Environmental Health Sciences (NIEHS), and Michael Lowit, U.S. Environmental Protection Agency (EPA) Office of Pesticide Programs. Mansouri will discuss the Collaborative Acute Toxicity Modeling Suite (CATMoS), a global project to develop predictive in silico models for assessing chemical safety. These models cover five endpoints relevant to regulatory frameworks and are now being evaluated for use by the EPA. Lowit will describe a collaboration between EPA, NICEATM, and the Humane Society of the United States to apply CATMoS to predicting acute toxicity of technical grade active ingredients for pesticides registered by the EPA.

The EPIC series covers timely topics on the use of NAMs for risk assessment within EPA and the California Department of Pesticide Regulation (CDPR).

An ICCVAM document, “Validation, Qualification, and Regulatory Acceptance of New Approach Methodologies,” is now available. This document updates a model for validation and regulatory acceptance of new and alternative test methods originally described in the 1997 ICCVAM report, “Validation and Regulatory Acceptance of Toxicological Test Methods.” The updated document describes an approach to NAMs validation that reflects modern toxicity testing, placing less emphasis on replacement of in vivo tests with a single alternative method and more emphasis on integrating results from multiple in vitro and in chemico assays and in silico approaches. Guided by the principles articulated in the 2018 ICCVAM Strategic Roadmap, the new document presents a more flexible approach to how confidence is established, to help ensure the adoption of new methods by federal agencies and regulated industries once validated for a specific application or context of use.

The new document was prepared by the ICCVAM Validation Workgroup, which was established in 2021 to update the 1997 document. It reflects input from a number of federal research and regulatory agencies, as well as public comments received following the release of a draft version before the 2023 meeting of the Scientific Advisory Committee on Alternative Toxicological Methods.

A webinar on February 23, 10:00–11:00 a.m. EST, will discuss “Carcinogenomics – Assessing the Tumorigenic Potential of Chemicals Through Genomic Biomarkers to Reduce the Reliance on the Rodent Cancer Bioassay.” The webinar is hosted by the Society of Toxicology Carcinogenesis Specialty Section.

The rodent assay has been the long-required study for regulatory assessment of carcinogenic hazard and risk. However, recognition of genomic biomarkers as reducing the need for these conventional methods is growing within the scientific community. The goal of this research is to construct and qualify liver transcriptomic biomarkers of key molecular initiating events in short-term rat studies that inform on liver tumorigenic risk in the rodent cancer bioassay. This webinar describes a collaborative approach to develop and qualify biomarker gene expression panels that measure widely accepted molecular pathways linked to tumorigenesis and their activation levels to predict doses of chemicals from short-term exposures. Successful efforts will facilitate transition from current heavy reliance on conventional rodent cancer bioassays to more rapid animal- and resource-sparing approaches.

Speakers:

• Keith Tanis, Merck
• Connie Mitchell, HESI
• Udayan Apte, University of Kansas Medical Center

A new paper describes how NICEATM scientists and collaborators in other offices within the National Institute of Environmental Health Sciences developed automated tools to support standardization of extracted toxicological endpoint information by applying preexisting controlled vocabularies. Augmenting manual efforts with automation tools increased the efficiency of producing a findable, accessible, interoperable, and reusable (FAIR) dataset of regulatory guideline studies. This open-source approach can be readily applied to other legacy developmental toxicology datasets, and the code design is customizable for other study types.

An article on Charles River Laboratories’ Eureka blog, “Can Scientific Research Thrive Without Animals?” discusses the impact of the FDA Modernization Act 2.0 on advancing alternatives to animal use for safety testing. The article highlights the role of ICCVAM and NICEATM in demonstrating which non-animal methods are as good if not better than the conventional tests done in animals. NICEATM Director Nicole Kleinstreuer is extensively quoted in the article, which presents the NICEATM uterotrophic database as an example of data resources that are needed to evaluate in vitro test methods and to build predictive in silico models. 

A virtual workshop, held on May 16 at 10:00 a.m. EST, will explore animal methods bias in funding. The workshop is hosted by the Coalition to Illuminate and Address Animal Methods Bias (COLAAB), an international collaboration of researchers and advocates aiming to provide concrete evidence on the existence and consequences of this bias, and to develop and implement solutions for overcoming it.

“Animal methods bias” is defined as the preference for animal-based research methods, which affects the fair consideration of animal-free approaches and hampers their update and dissemination. Non-animal new approach methodologies (NAMs) have advanced rapidly over the last decade. But because animals are still considered by many to be the “gold standard” for biomedical research, studies that do not use animals can be assessed in a biased manner. Evidence of this bias has been established in the realm of publishing as a condition for publication. Anecdotal evidence suggests this problem may also affect the assessment of grant proposals, imposing a funding barrier for research using NAMs. Participants in this workshop will gather perspectives on this issue from a variety of stakeholders, characterize animal methods bias in funding, and identify potential solutions, both individual and structural.

A public workshop, “Future Implications of Open-Access & FAIR Data Practices on Chemistry and Chemical Engineering Publications” will be held February 21-22. The event is hosted by a planning committee of the National Academies of Sciences, Engineering, and Medicine, and will be held in Washington, DC, and virtually.

Workshop participants will discuss the various benefits and issues related to open access and FAIR (Findable, Accessible, Interoperative, Reusable) data practices for chemistry and chemical engineering research and publications. The workshop will provide a forum to explore social, financial, scientific, and research impacts of transitioning into open access and FAIR data practices.

A new publication by United Kingdom National Center for the 3Rs and the British Toxicology Society has identified actions to allow the United Kingdom to develop a world-leading regulatory framework that firmly embeds the 3Rs in chemical safety testing. The paper sets out the investment and commitment required to improve domestic chemical safety regulation and enable the use of the latest technological and scientific developments. Four key areas where progress is needed are identified as:

• A shared aspiration and desire to modernize the chemicals regulation framework to ensure the highest protection of human health, safeguard the environment, and stimulate the economy.
• A long-term financial commitment by government combined with clear and decisive leadership and ambition.
• A coordinated approach to deliver a new regulatory framework that facilitates cooperation between regulatory agencies and provides the necessary training and career structure that encourages the recruitment and retention of strong scientific talent.
• Harmonization of approaches worldwide to promote a more modern approach to chemicals regulation that fosters international cooperation and trade. 

Slides and video from the ICCVAM Communities of Practice webinar, “Emerging Approaches for Anchoring Biological Relevance of New Approach Methodologies” are now available. This webinar discussed approaches to evaluating NAMs that are based on evaluating the biological relevance of the NAM to the species of regulatory interest.

A February 1 statement from NIH Director Monica Bertagnolli announced NIH acceptance of a working group's recommendations of activities on NAMs. 

A working group of the Advisory Committee to the Director was charged with identifying areas in which the development and use of novel alternative methods provide maximal value to biomedical research. The working group’s activities culminated in a December 2023 report to the Advisory Committee with seven specific recommendations on how NIH should work with the community to support development and use of NAMs. In her statement,  Bertagnolli noted how the recommendation build on an existing foundation of NIH investment in NAMs projects as NIH continues to advance the validation and regulatory implementation of NAMs in partnership with other federal agencies via ICCVAM.

On January 25, the NIH Council of Councils approved the concept for the new NIH Common Fund's Complement Animal Research In Experimentation (Complement-ARIE) program. Complement-ARIE will speed the development, standardization, validation, and use of human-based NAMs, and significantly advance understanding of human health and disease by providing a range of ready and standardized biomedical research models. Developing these models will require expertise in disease research, personalized medicine, and in screening therapeutics for safety and effectiveness. Complement-ARIE will bring together experts in these areas via efforts such as technology development projects and centers, resource coordinating centers, validation networks, community engagement and training, and strategic key-partner engagement.

A January 29 webinar will focus on “Implementing Computational Approaches for Regulatory Safety Assessments” This webinar is the latest in the Communities of Practice series presented by NICEATM on behalf of ICCVAM.

Computational toxicology methods can be useful for generating bioactivity predictions for chemicals for which limited toxicity data are available. They can also help users understand and interpret large, diverse bioactivity data sets, or predict how a chemical might behave in the body. However, users with limited experience with such methods may find it difficult to use them or interpret their outputs, or even understand how the methods could be applied in a specific context.

This webinar will cover how to establish confidence in computational approaches for regulatory applications. Ongoing activities and key insights will be described in three presentations by speakers from the U.S. government and the private sector focusing on applications of tools such as structure-based models to predict chemical bioactivity and pharmacokinetic models to support understanding of chemical metabolism and disposition.

In a Federal Register notice published January 9, the U.S. Environmental Protection Agency (EPA) announced a new framework for identifying eye irritation and corrosion hazards for new chemicals reviewed under the Toxic Substances Control Act (TSCA).

With this new framework, EPA will place increased weight on data from non-animal test methods that are more reproducible and provide results more relevant to humans. This will streamline the decision-making process and increase efficiency through a standard process for EPA to use each time it evaluates eye irritation or corrosion hazards test data. The new framework supports EPA’s mandate under TSCA to promote the development and implementation of alternative test methods and strategies that can provide information on chemical hazards without animal testing. This framework also supports EPA’s ongoing efforts to reduce the use of animal testing and make the Agency’s review of new chemicals more efficient, helping to bring new chemicals to market more quickly while protecting human health

Defined approaches for skin sensitization (DASS) identify potential chemical skin sensitizers by integrating data from multiple non-animal tests based on human cells, molecular targets, and computational model predictions using standardized data interpretation procedures. While several DASS are internationally accepted by regulatory agencies, the data interpretation procedures vary in logical complexity, and manual application can be time-consuming or prone to error. A new paper describes the DASS App, an open-source web application to facilitate user application of three regulatory testing strategies for skin sensitization assessment.

A detailed description of the platform is published in an article (Dorne et al.) in the EFSA Journal, available at https://doi.org/10.2903/j.efsa.2023.e211101.

Registration is now open for a webinar on “Accurate evaluation of hepatocyte metabolisms on a nobel oxygen-permeable material with low sorption characteristics,” on Monday, December 11 from 9:00 to 10:00 a.m. EST. This webinar is presented by the American Society for Cellular and Computational Toxicology (ASCCT), the European Society of Toxicology In Vitro, and the Japanese Society for Alternatives to Animal Experiments. To register for the webinar, visit the ASCCT event calendar page and click on the event title in the right sidebar.

Primary cultured hepatocytes are often used to assess hepatic metabolism and toxicity in vitro, but a drawback to this model is the functional deterioration upon isolation due to the lack of a physiological environment. Researchers have reported that culturing hepatocytes in microphysiological systems using polydimethylsiloxane (PDMS) improves the function of isolated hepatocytes by its high oxygen permeability. However, the high chemical sorption property of PDMS has impeded its practical use in drug development. In this webinar, Masaki Nishikawa, University of Tokyo, will describe his group’s evaluations of a new culture material, 4-polymethyl-1-pentene polymer (PMP), comparing it to PDMS and conventional tissue culture polystyrene. Using primary rat hepatocytes, they found that PMP represents a superior alternative to both PDMS and TCPS, making it a promising material for various drug testing systems. High levels of liver function were maintained at least for 1 week on PMP. They also demonstrated that low chemical sorption characteristics and high oxygen permeability of PMP were key factors in both exploiting the potential of primary cultured hepatocytes and performing an accurate evaluation of hepatic metabolism.

Registration is now open for a webinar on “ToxPi: visual analytics for communicating integrated models from environmental health and toxicology,” on Wednesday, January 10, 2024. This webinar is presented by the Applied Genetic Toxicology Special Interest Group of the Environmental Mutagenesis and Genomics Society.

The ToxPi (Toxicological Prioritization Index) framework provides tools for integrating, visualizing, and communicating complex data sets. ToxPi was originally developed for assessing the relative toxicity of multiple chemicals or stressors by synthesizing complex toxicological data to provide a single comprehensive view of the potential health effects. It continues to be used for profiling chemicals and has since been applied to other types of “sample” entities, including geographical data and other profiling applications. In this webinar, David Reif, National Institute of Environmental Health Sciences, will introduce the ToxPi methodology and survey recent applications in risk assessment and decision support. The presentation will describe new methodological extensions, including a bidirectional ToxPi and artificial intelligence/machine learning-guided weight optimization, and introduce integrated software applications beyond those available in previous releases.

Presentation slides and videos from the webcast of the September 21-22 meeting of the Scientific Advisory Committee on Alternative Toxicological Methods (SACATM) are now available. Meeting minutes are currently being reviewed by the committee and will be posted on this page when they are available.

NICEATM and U.S. Environmental Protection Agency (EPA) scientists and collaborators have published results from testing 29 agrochemical formulations in defined approaches (DAs) for eye irritation. Hazard classification concordance was assessed using orthogonal validation rather than direct concordance analysis with the historical in vivo rabbit eye data, the standard used for agrochemical formulations in some countries. The in vitro and ex vivo methods used in the DAs were demonstrated to be as or more fit for purpose and reliable and relevant than the in vivo rabbit test, thereby increasing scientific confidence in the use of these DAs for assessing eye corrosion/irritation potential of agrochemical formulations.

Presenter’s abstract: Jo Nyffeler, Helmholtz Centre for Environmental Research – UFZ. “Cell painting” is an imaging-based, high-throughput method to obtain phenotypic information of individual cells. Initially used mainly in pharma industry for hit discovery, cell painting can be applied to other research questions, such as safety assessment. This presentation will describe the applicability of cell painting and how it can be used to obtain in vitro potency estimates for chemicals that can be compared to exposure information, and can be used to group chemicals with similar mode-of-actions. Cell painting highlights critical differences that would not have been apparent when only looking at structural information. This webinar will give an overview of possible application of cell painting in the context of safety assessment.

Registration is now open for a webinar on “The role of mixtures for effect-based trigger values in water quality assessment,” on Tuesday, November 14 from 10:00 to 11:00 a.m. EST. This webinar is presented by the American Society for Cellular and Computational Toxicology (ASCCT) and the European Society of Toxicology In Vitro. To register for the webinar, visit the ASCCT event calendar page and click on the event title in the right sidebar.

Presenter’s abstract: Beate Escher, Department of Cell Toxicology, Helmholtz Centre for Environmental Research – UFZ, Leipzig, Germany. Bioanalytical tools have been applied for monitoring of water quality worldwide for several decades. Most research has focused on surface waters and domestic and industrial wastewaters. Cell-based bioassays have been used for benchmarking drinking and surface water quality as well as assessing treatment efficacy of wastewater and advanced water treatment. A lack of trigger values and interpretation guidelines has hampered greater adoption of bioanalytical tools for (regulatory) monitoring applications. This presentation will give an overview on the derivation of effect-based trigger (EBT) values for human health (drinking water) and the environment (surface water). These EBT are designed to be protective for mixture effects stemming from chemical cocktails in water.

A new publication by NICEATM scientists and German government collaborators announces the availability of a large high-quality set of human skin sensitization data. This data set, which has already supported international acceptance of a non-animal strategy for identifying skin sensitizers, is now available to any researcher for developing evaluating additional test methods.

Computational and cell-based methods show promise for replacing animals for chemical safety testing. However, high-quality data, preferably from humans, are needed to demonstrate that new methods can reliably identify whether a chemical could be toxic to humans. The data set described in this paper is the largest set of human data ever assembled for the purpose of evaluating non-animal approaches for chemical safety testing.

The European Partnership for Alternatives to Animal Testing (EPAA) invites the submission of solutions based on NAMs to inform the development of a future classification system for systemic toxicity of human health based on the activity and potential systemic availability of chemicals.

• The NAM-based classifications should reflect levels of concern related to, but not synonymous with, the current classification system addressing systemic toxicity.
• The NAMs do not need to literally predict the outcomes of animal studies, nor are they expected to reproduce existing classifications.

Resources on the project webpage include a recording of a July 13 webinar describing the project.

EPAA will provide a reference list of approximately 150 chemicals, along with identifiers reflecting three levels of concern. The number of chemicals in each class (High, Medium, and Low) will also be provided, but participants will not be told which chemical belongs to which class. Submitters will be expected to propose prototype NAM-based solutions that categorize some or all of the chemicals on the reference list. In this initial prototype phase, specific data generation is not necessarily required, but rather ideas for a NAM-based classification scheme can be explored using existing information. EPAA will provide a reporting template, including guidance. Interested persons can email [email protected] to request updates on the designathon.

NICEATM and collaborators are organizing an October 11-12 workshop “Trust Your Gut: Establishing Confidence in Gastrointestinal Models, an Overview of the State of the Science and Contexts of Use.” The workshop will be at the Porter Neuroscience Research Center at the National Institutes of Health in Bethesda, MD, and will also be webcast. A series of three webinars presented from September 18-October 6 will introduce the three principal topics of the workshop: (1) de-risking systemic toxicity and understanding absorption/pharmacokinetics; (2) gastrointestinal toxicity; and (3) evaluating potential allergenicity. Registration for both the webinars and the workshop is now open.

The gastrointestinal tract (GIT) is one of the most common chemical exposure routes. Orally administered substances are first metabolized by the GIT, and both parent substance and metabolites can be absorbed through and potentially damage the GIT. Since toxicity in the GIT can result in systemic toxicity, screening of potential toxicants using GIT models could provide an efficient way to identify potential systemic toxicants. Even in the absence of toxicity, understanding GIT absorption can inform the potential for toxicity in other target organs. While in vivo rodent studies have historically been used for understanding GIT absorption and toxicity, animal models have well-documented differences from humans. Mammalian cell culture methods of varying complexity can be used in a variety of applications including rapid response, metabolism/metabolite secretion, and microbiome studies, and generating data for pharmacokinetic modeling. This workshop will examine the state of the science for using new approach methodologies (NAMs) to predict GIT absorption and toxicity.

The Coalition to Illuminate and Address Animal Methods Bias (COLAAB) presents “The Author Guide for Addressing Animal Methods Bias in Publishing” in an interactive virtual event on Wednesday, November 8 from 9:00-10:30 a.m. ET. COLAAB is an international collaboration of researchers and advocates gathering information evidence of animal methods bias and mitigating its detrimental effects on biomedical research.

There is growing recognition that animal methods bias, the preference for animal-based methods where they are not necessary or where nonanimal methods are suitable, can impact the likelihood or timeliness of manuscript acceptance for publication. The guide was developed to aid researchers in responding to animal methods bias from manuscript reviewers. 

A comprehensive review paper on in vitro to in vivo extrapolation (IVIVE) with authors from eight ICCVAM member agencies and the European Union has been named by the journal Toxics as one of its “Hot Review Papers” for 2021-2022. 

The IVIVE review proposes operational definitions for IVIVE, presents literature examples for several common toxicity endpoints, and highlights their implications in decision-making processes across various federal agencies and international organizations. Current challenges and future needs in applying IVIVE are also summarized. Xiaoqing Chang (Inotiv, contractor supporting NICEATM) was first author on the paper.

The European Partnership for Alternatives to Animal Testing (EPAA) invites the submission of solutions based on new approach methodologies (NAMs) to inform the development of a future classification system for systemic toxicity of human health based on the activity and potential systemic availability of chemicals.

• The NAM-based classifications should reflect levels of concern related to, but not synonymous with, the current classification system addressing systemic toxicity.
• The NAMs do not need to literally predict the outcomes of animal studies, nor are they expected to reproduce existing classifications.

EPAA will provide a reference list of approximately 150 chemicals, along with identifiers reflecting three levels of concern. The number of chemicals in each class (High, Medium, and Low) will also be provided, but participants will not be told which chemical belongs to which class. Submitters will be expected to propose prototype NAM-based solutions that categorize some or all of the chemicals on the reference list. In this initial prototype phase, specific data generation is not necessarily required, but rather ideas for a NAM-based classification scheme can be explored using existing information. EPAA will provide a reporting template, including guidance. Interested persons can email [email protected] to request updates on the designathon.

A virtual workshop on June 29-30 will assess the current state of the science of using signatures from “omic” data types to link environmental exposures to cancer.

Greta Schoeters, University of Antwerp, and Mirjam Luitjen, Netherlands National Institute for Public Health and the Environment, will discuss “Human biomonitoring to support risk assessment and chemical policies in Europe: results from HBM4EU.” Human biomonitoring (HBM) measures chemicals or their metabolites directly in human tissues or fluids and hence aggregates chemical exposure from different sources and intake routes. HBM provides a picture of real-life exposure to chemicals, which is essential information for hazard characterization and chemical risk assessment. This presentation will discuss a coherent HBM framework to track progress towards reducing pollution levels to no longer be harmful to health by 2050. HBM4EU has set up a laboratory network to produce comparable high quality analytical data, provide wide access to data, and facilitate interpretation of results by developing indicators and human biomonitoring guidance values. The HGM4EU project demonstrated not only regulations but clear strategies are needed to prevent further pollution on the human body.

Recordings and other materials from this webinar will be posted on the ASCCT webinar archive shortly after the webinar’s close.

FDA has finalized the guidance document, “Nonclinical Evaluation of the Immunotoxic Potential of Pharmaceuticals.” The purpose of this guidance is to assist sponsors in the nonclinical evaluation of the immunotoxic potential of drug products and biopharmaceuticals.

The guidance addresses evaluation of topical pharmaceuticals for skin sensitization potential. Specifically, the guidance states that, for individual chemicals, “FDA will consider a battery of studies (e.g., in silico, in chemico, in vitro) that have been shown to adequately predict human skin sensitization with an accuracy similar to existing in vivo methods.”

In a May 30 press release, the European Chemicals Agency (ECHA) announced that it has published its fifth report on the use of alternatives to testing on animals for the Regulation for Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). The report finds that progress is being made in the increased use of alternatives to gather data on the properties of substances, in place of animal testing. The most common applications include testing waivers and data-based approaches to predicting chemical properties, such as read-across, modeling, or weight-of evidence analyses. However, there has been a notable increase in the use of in vitro test methods, which involve studies with cells, tissues, or organs. These are used specially to obtain data for skin corrosion/irritation, serious eye damage/eye irritation and skin sensitization. 

The U.S. Consumer Product Safety Commission (CPSC) has updated its Animal Testing web page. It has been re-designed to be more user friendly and have direct access to necessary information and documents. 

The U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA) and the Occupational Safety and Health Administration (OSHA) will hold a hybrid public meeting on Wednesday, June 21.

• Liver Spheroids as an In Vivo Like Human In Vitro System for Prediction of Nonalcoholic Steatohepatitis (NASH), Drug Metabolism, and Drug-Induced Hepatotoxicity: Magnus Ingelman-Sundberg, Karolinska Institutet. Liver toxicity is a significant contributor to safety failures in drug development. This lecture will explore recent applications of liver spheroids for analyzing drug-induced liver toxicity, evaluating the disposition and metabolism of low clearance drugs, and developing treatments for metabolic and infectious liver diseases.
• In Vitro Prediction of Liver Toxicity Using Adverse Outcome Pathways: Mathieu Vinken, Vrije Universiteit Brussel. Many adverse outcome pathways (AOPs) and AOP networks related to liver toxicity have been introduced over the past decade. This webinar will focus on the development and practical validation of an AOP network mechanistically describing the accumulation of noxious bile acids in the liver induced by chemical compounds, including pharmaceutical drugs, food additives, and cosmetic ingredients. It will be demonstrated how this AOP network can serve as the conceptual basis for reliable in vitro detection and prediction of chemical-induced cholestatic liver injury.

NICEATM and collaborators are planning a workshop to examine the state of the science for new approach methodologies (NAMs) models of the gastrointestinal tract (GIT) and the context of use of such models for regulatory consideration. The workshop will be held in person at the Porter Neuroscience Center at the National Institutes of Health in Bethesda, MD, on October 11-12. A webinar series to provide background information for the in-person workshop is planned for September.

The GIT is one of the most common chemical exposure routes, and toxicity to the GIT typically results in systemic toxicity. Even in the absence of GIT toxicity, understanding gut absorption provides insight into systemic exposure levels that inform upon the potential for toxicity in other target organs. In vivo rodent studies have historically been used for understanding both GIT absorption and toxicity, but they have well documented anatomical, physiological, and biochemical differences from humans. The goal of this workshop is to consider the state of the science of mammalian cell culture models and other NAMs in the context of regulatory needs for assessing GIT exposure and toxicity.

NICEATM requests nominations of topics and speakers for the workshop and preceding webinars. Topics could include, but are not limited to:

• NAMs to evaluate GIT toxicity.
• NAMs to evaluate GIT absorption and metabolism.
• How GIT toxicity models might integrate the microbiome.
• Current use of GIT NAM models, including context of use.
• Integrating human genetic diversity into GIT NAM models.

To nominate a topic and/or speaker, please contact Amber Daniel at [email protected] by Friday, June 30.

NICEATM and collaborators will present a May 31-June 1 virtual workshop focused on advancing microphysiological systems (MPS) for understanding and treating infectious diseases. “From Research to Readiness: Advancing Research and Regulatory Acceptance of Microphysiological Systems for Infectious Disease Applications” will facilitate discussion and collaboration about current regulatory approaches and to raise awareness of opportunities for accelerating the integration of MPS models in the regulatory framework.

The workshop will feature presentations on MPS models for infectious disease research and where they are in terms of readiness as well as presentations from international regulators. There will be opportunities for registered participants to ask clarifying questions about the presentations during the event, as well as opportunities for group discussion.

The workshop is being organized by the Microphysiological Systems for COVID Research (MPSCoRe) working group, which was organized to coordinate the use of MPS to reduce animal use in studies of COVID-19 and other infectious diseases. 

An upcoming webinar, “Time for a Change: Evidence-Based Approaches for the Biological Safety Assessment of Medical Devices," examines the problems with current medical device biological safety assessment approaches and suggests that evidence-based strategies could be the solution. The webinar will be hosted live and available on-demand Thursday, May 25 at 2:30 p.m. ET. The webinar is presented by The Scientist magazine and sponsored by Sartorius.

In the webinar, Ron Brown, Director, Risk Science Consortium, discusses:

• The problems associated with current approaches used to assess the biological safety of medical devices.
• The development of an evidenced-based toxicology (EBT) approach for assessing the validity of new and existing testing strategies.
• How to incorporate data-driven methods into a streamlined workflow for medical device safety assessment.
• The implications of this proposed approach for patients, test method developers, medical device manufacturers, and regulatory agencies.

Brown is a board-certified toxicologist with 35 years of experience in regulatory toxicology and risk assessment, including over 20 years spent at FDA.

EPA's Generalized Read-Across (GenRA) tool is a publicly available, automated approach to make reproducible read-across predictions of toxicity. Read-across is a commonly used data gap-filling technique whereby endpoint information for one substance is used to predict the same endpoint for another substance, supported by structural or other feature similarities. While read-across is sometimes reliant on subjective or expert judgement, the GenRA tool can provide more objective and reproducible read-across predictions.

A free virtual training session on GenRA will be presented on Tuesday, May 23, from 11:00 a.m.-1:30 p.m. EDT. Specifically targeted for decision-makers, this training will provide:

• An overview of GenRA's purpose and scope.
• Demonstration of GenRA's interface and navigation.
• Opportunities for participatory learning and engagement.

This training will feature Grace Patlewicz of the EPA Center for Computational Toxicology and Exposure (CCTE). It will include a plenary presentation, small group discussions, and a chance to try out your skills with GenRA. The training is divided into two parts to accommodate a variety of interests and schedules. Registration for one or both sessions is required.

Session 1 (Presentation and Q&A) 11:00 a.m. - 12:30 p.m. EDT

This session will provide an overview of GenRA content and function with opportunities for participation and Q&A.

Devon Barnes, Utrecht Institute for Pharmaceutical Sciences, will describe “Development of an Adverse Outcome Pathway for Kidney Tubular Necrosis.” An ontological knowledge framework was developed to support predicting systemic repeated-dose toxicity effects of nephrotoxic chemicals associated with kidney tubular necrosis. Data extracted will assess confidence levels in previously described key events (KEs) and key event relationships and identify potential new KEs. The resulting adverse outcome pathway network will form the conceptual basis for establishing a test battery of in vitro assays to characterize nephrotoxic chemicals.

Job Berkhout, RIVM, will discuss “Computational Modelling of Neural Tube Closure Defects.” The study aim was development of an in silico model of human neural tube closure. A physiological map of human neural tube closure was used to build a multicellular agent-based model of the all-trans-retinoic acid related molecular pathways that leads to closure of the neural tube. The morphogenetic events driven by gene expression changes are visualized by the computational model. The computational model will be applied to predict chemical-induced changes in gene expression and cell characteristics. The predictions of the model will be validated using a set of dedicated in vitro assays in conjunction with existing knowledge on in vivo developmental neurotoxicity. Such computational models may ultimately provide an alternative in silico approach for chemical safety assessment without the use of animals.

The defined approaches predict skin sensitization hazard (either a sensitizer or non-sensitizer) and potency by integrating data from in vitro assays and in silico hazard predictions. 

ASCCT and ESTIV will present a webinar on “New approach methodologies for evaluating cardio- and developmental toxicity” on Friday, March 24 from 10-11 a.m. EDT. Registration is required to attend. 

Presenters’ abstracts:

• A multiorgan on-chip platform for the in vitro investigation of off-target cardiotoxicity of liver-metabolized anticancer drugs – Erika Ferrari (BiomimX Srl). Off-target cardiotoxicity is one of the main causes of drug withdrawal from the market. Multiorgan-on-chip (MOoC) platforms represent a disruptive solution to predict liver metabolism on off-target organs to ultimately improve drug safety testing during drug development. This project integrates liver and cardiac models in a compartmentalized valve-based MOoC and shows its application in studying the effects of liver-metabolized terfenadine on cardiac microtissues.
• Predicting developmental toxicity of pyrethroid insecticides in vitro using human-induced pluripotent stem cells - Yanying Ma (National Food Institute, Technical University of Denmark). Metabolites of pyrethroid insecticides are detected in most urine samples from the general population. Pyrethroids are suspected to be cardiotoxic and to interfere with thyroid hormones that are essential for fetal brain development. Thus, exposure to pyrethroids during vulnerable windows in pregnancy may adversely affect child neurodevelopment and cardiovascular health. The project findings highlight the risks posed by insecticides on human fetal development, supporting the need to restrict their use in order to reduce human exposure.

This presentation will describe how liver and cardiac models can be integrated in a compartmentalized value-based MOoC, and demonstrate application of the MOoC in studying the effects of liver-metabolized terfenadine on cardiac microtissues.
• Predicting developmental toxicity of pyrethroid insecticides in vitro using human-induced pluripotent stem cells: Yanying Ma, National Food Institute, Technical University of Denmark. Metabolites of pyrethroid insecticides are detected in most urine samples from the general population. Pyrethroids act primarily by interfering with voltage-gated sodium channels, which are essential for nerve cell function and cardiac muscle contraction. Therefore, pyrethroids are suspected to be cardiotoxic. Furthermore, pyrethroids are suggested to interfere with thyroid hormones that are essential for fetal brain development. This presentation will describe the risks posed by insecticides on human fetal development, supporting the need to restrict their use in order to reduce human exposure.

In a January 19 Federal Register notice EPA announced availability of a draft white paper, “Availability of New Approach Methodologies (NAMs) in the Endocrine Disruptor Screening Program (EDSP).” The white paper states that certain NAMs have been validated and may now be accepted by the EPA as alternatives for certain Tier 1 assays used within the EDSP. Others NAMs may be useful for prioritization purposes and for use as other scientifically relevant information, where appropriate, in weight-of-evidence evaluations. EPA is accepting comment on the draft white paper through March 20.

The EDSP was established by the Federal, Food, Drug and Cosmetic Act, which required EPA to develop a screening program to determine whether certain substances may have effects in humans similar to effects produced by naturally occurring estrogens or other endocrine effects. The purpose of Tier 1 EDSP screening is to identify chemicals that have potential biological activity in the estrogen, androgen, or thyroid hormone pathways. Recent EPA research efforts have focused on the development and evaluation of high-throughput in vitro assays and in silico methods as NAMs, including databases and computational models, for use as alternatives to the current suite of assays in the EDSP Tier 1 battery, to accelerate the pace of screening, add efficiencies, decrease costs, and reduce animal testing.

A January 30 webinar will focus on “Emerging Approaches for Anchoring Biological Relevance of New Approach Methodologies.” This webinar is the latest in the Communities of Practice webinar series presented by NICEATM on behalf of ICCVAM. 

“New approach methodologies” (NAMs) refers to approaches that can be used alone or in combination to provide information on chemical hazard and risk assessment without traditional animal tests. Traditional approaches to evaluating NAMs consider how well the results of chemical tests using NAMs correspond with the results of animal tests of the same chemicals. However, the usefulness of this approach is limited, especially when the animal results are variable or the animal model does not adequately represent the species or effect of regulatory interest. This webinar will discuss approaches to build confidence in NAMs that are based on evaluating the biological relevance of the NAM to the species of regulatory interest. Ongoing activities and key insights will be described in three presentations by speakers from the academic and private sector focusing on applications of small model organisms, organs-on-chips, and models of absorption, distribution, metabolism, and excretion.

Presenters’ abstracts:

• Facilitating Global Connections through the Microphysiological Systems for COVID Research (MPSCoRe) Working Group – Amber Daniel, Inotiv, contractor supporting NICEATM. The emergence and global spread of COVID-19 emphasizes the need for effective approaches to prevent, control, and treat infectious diseases. Human cell-based in vitro platforms known as microphysiological systems (MPS) have the potential to effectively model the human lung and other organ systems affected by COVID-19. The MPSCoRe working group was organized to connect key MPS stakeholders to maximize the impact of MPS technologies in understanding disease mechanisms and treatments and reducing animal use while improving human health.
• Applying Deep Learning Toxicity Models Across the Chemical Universe – Sunggun Lee, Duke University. Traditional toxicity testing generally relies on in vivo or in vitro methods, which are time-consuming, resource-intensive, and frequently result in flawed generalizations to humans. This project refined two novel deep learning models originally developed by FDA. DeepCarc and DeepDILI predict endpoints for carcinogenicity and drug-induced liver injury. These computational models rapidly screen large chemical libraries to prioritize potentially hazardous substances for further examination. Lee conducted this project while a summer student at NIEHS under the mentorship of NICEATM Director Nicole Kleinstreuer.

Shagun Krishna, a postdoctoral fellow within the NICEATM group, has received one of five 2022 Young Researcher Prizes awarded internationally by the Lush Prize. Krishna’s research involves development of a pipeline for cardiovascular risk assessment of pharmaceutical and environmental chemicals. She has led a project to interpret Tox21/ToxCast high-throughput screening assay data, map the assay targets to biological pathways that represent key failure modes in cardiovascular disease, and use the observed patterns of bioactivity to screen and rank chemicals for potential cardiotoxicity. Her research applies cheminformatics, artificial intelligence, and machine learning in a variety of ways, including building structure–activity relationship models and developing evidence maps of the literature supporting environmental contributions to cardiovascular effects.

The Lush Prize offers a global prize fund to support initiatives to end or replace animal testing. This year’s nominees included 65 organizations and representatives from 26 countries. The Young Researcher Prizes are awarded to five young scientists who are focusing their careers on advancing replacements to animal testing. Past Lush Young Researcher Prize winners include NICEATM Director Nicole Kleinstreuer and NICEATM scientist Kamel Mansouri.

An October 26-27 NICEATM symposium webinar will consider “Using New Approach Methodologies to Address Variability and Susceptibility Across Populations.” The goals of the symposium webinar are to identify opportunities for NAMs to provide relevant information on population variability and susceptibility to environmental chemicals; and identify information needs where NAMs could be designed or improved to fill that need. A webinar series presented by NICEATM and the Physicians Committee for Responsible Medicine provided background information for the symposium webinar.

On Wednesday, November 3 at 11:00 a.m. EDT, ScitoVation will present “New Approach Methodologies for Genetic Toxicity Assessment and Regulatory Evaluation of New and Existing Substances.”

Genetic toxicity assessments evaluate the ability of a chemical to damage genetic material and are a critical component of chemical risk assessment. Most tests currently used to assess genetic toxicity are laborious, time-consuming, or require animal testing, and fail to provide information to support quantitative dose-response analyses. However, higher throughput NAMs for genetic toxicity assessments can provide efficient, animal-free chemical safety assessments. Data from these NAMs can be analyzed using in vitro to in vivo extrapolation (IVIVE) models to estimate points of departure for genotoxicity endpoints and modernize the assessment of genotoxic substances. Health Canada scientists have developed an integrated in vitro NAM platform for the assessment of chemically induced genetic toxicity. In this webinar, Alexandra Long of Health Canada will provide an overview of this project and describe a case where IVIVE was applied to genetic toxicity data to derive points of departure that are protective of human health.

The Pharmaceutical and Bioscience Society International will present an online workshop on “Microphysiological Systems (MPS) as a Tool for Drug Candidate Evaluation: Technologies, Applications, and Regulatory Aspects” on Friday, October 21, from 11:30 a.m. to 4:00 p.m. EDT (8:30 a.m.-1:00 p.m. Pacific time). The workshop is free but you must create an account with the society to register.

MPS are complex in vitro models that mimic physiologically relevant functions of animal or human organs and tissues. These models have the potential to predict both the efficacy and safety of new drugs. This workshop will consider how MPS technologies, such as organ-on-a chip, are being applied during drug development, challenges to the adoption of MPS, and regulatory considerations. This workshop will provide an introduction/overview to MPS, as well as a deeper dive into organ systems such as liver, cardiovascular, and skin.

On Thursday, October 27, Cruelty Free Europe will present “Target Zero: Routes to a Toxic-free Europe Without Animal Testing.” The webinar will take place from 4:00-9:45 a.m. EDT (10:00 a.m.-3:45 p.m. Central European time).

In October 2020, the European Commission adopted its Chemicals Strategy for Sustainability (CSS), part of the European Union’s zero pollution ambition. The strategy’s goals are better protection of citizens and our environment from harmful chemicals and the promotion of safer and more sustainable chemicals. However, changes to key chemicals legislation under the CSS could trigger an increase in animal testing with questionable chances of success for better protection for human health and the environment. This webinar will bring different sectors together to show how we can plot a route to a toxic-free environment using animal-free testing and research. Acting NICEATM Director Nicole Kleinstreuer will be speaking at the event.

The World Health Organization (WHO) and NC3Rs are conducting a review of animal use requirements within WHO guidelines for biologics. As part of that effort, NC3Rs is hosting a series of regional workshops to better understand the potential impact of these changes on manufacturers and regulators globally.

A virtual workshop on Monday, September 26 will focus on requirements in North and South America. Biologicals regulatory agencies and manufacturers from the region will discuss their perspectives on current testing strategies and how changes to WHO guidelines could be implemented to support wider adoption of 3Rs and non-animal approaches. Although the discussions are focused on Pan-America, relevant stakeholders from any region are welcome to attend and participate. 

Biologicals such as vaccines, cytokines, enzymes, and hormones are tested routinely after approval to ensure the safety and potency of products. Many of these tests currently require the use of animals, and a large number of animals are used for this purpose each year. The WHO/NC3Rs project, which is receiving support from NICEATM and FDA, is intended to support recommendations for where non-animal approaches can be adopted.

OECD has published seven new case studies on the use of integrated approaches for testing and assessment (IATA). OECD develops case studies on IATA to increase understanding and experience with these alternatives to animal testing and support their application to regulatory use. The case studies are issued as publications within the OECD Series on Testing and Assessment.

Two of the new case studies are relevant to recent NICEATM and ICCVAM activities.

• Series on Testing and Assessment No. 364, Case Study on the Use of Integrated Approaches for Testing and Assessment for DNT to Prioritize a Class of Organophosphorus Flame Retardants: This case study was prepared by a group of NICEATM scientists in collaboration with other NIEHS and EPA scientists. The case study uses a battery of in vitro and complementary non-mammalian animal models (e.g., zebrafish) to prioritize a class of compounds, organophosphorus flame retardants, for further developmental neurotoxicity (DNT) testing.
• Series on Testing and Assessment No. 367, Case Study on the Use of an Integrated Approach for Testing and Assessment (IATA) for New Approach Methodology (NAM) for Refining Inhalation Risk Assessment from Point of Contact Toxicity of the Pesticide, Chlorothalonil. This case study was developed from an investigation of how an in vitro respiratory model might improve on existing animal models to develop an inhalation exposure risk assessment for the pesticide chlorothalonil. The investigation was discussed in detail at a presentation given by EPA at the 2019 SACATM meeting.

An agenda is available for the virtual meeting of SACATM on Wednesday, September 21 and Thursday, September 22. Registration to view the meeting is open and will be available through the end of the meeting on September 22. Interested persons can also submit written comments or register to present oral comments during the meeting. Written comments and registration to present oral comments are due by Tuesday, September 13.

On June 30, OECD published six new test guidelines and 10 updated or corrected test guidelines. One of the new guidelines, “Test No. 467: Defined Approaches for Serious Eye Damage and Eye Irritation,” describes two approaches using non-animal methods and physicochemical properties to predict eye irritation hazard. It is the second guideline describing a defined approach published by OECD, following last year’s publication of Guideline 497 for predicting skin sensitization. Another new test guideline, Test Guideline 492B, describes a new stand-alone method for eye hazard potential using a reconstructed human corneal epithelium. Both new guidelines describe approaches that can replace animal use for eye irritation hazard classification. The updated guidelines include methods to assess skin sensitization, genotoxicity, and acute oral toxicity.

NICEATM and EPA scientists compiled, curated, and analyzed a set of over 2000 chemicals with multiple independent study records to characterize variability and reproducibility of results. Conditional probability analyses revealed that replicate studies only resulted in the same hazard categorization on average at 60% likelihood. The authors concluded that inherent biological or protocol variability likely underlies the variance in the results.

An upcoming webinar will describe the INSPiRE project, which assessed the value of in vitro models to predict the ability of chemicals to cause portal-of-entry effects on the human respiratory tract. The webinar will be presented by ScitoVation on June 1 at 11:00 a.m. EDT.

Because of differences in physiology, anatomy, and biochemistry between the rat and human respiratory tract and the way they limit the ability of the rat to predict human effects, there has been a shift to develop and use human cell-based approaches to characterize potential portal-of-entry effects of inhaled substances. In this webinar, Amy Clippinger and Andreas Stucki of the PETA Science Consortium International e.V. will describe how the INSPiRE project assessed four chemicals from two distinct chemical classes in two different cell systems using various exposure scenarios and biological endpoints. The results give important insights in how in vitro systems can be used to predict effects on the human respiratory tract and inform regulatory decision-making. All registered participants will receive access to the webinar recording.

To apply, submit a preproposal summarizing the proposed work, including descriptions of the project’s goal and the experimental design and methods to be used. Preproposals are due by April 15. Authors of accepted preproposals will be invited to submit full grant applications later in 2022.

Applications are still being accepted to attend the second Summer School on Innovative Approaches in Science, which will be held June 7-10 at the North Carolina Biotechnology Center in Research Triangle Park, NC. Applications will continue to be accepted while spaces remain. Attendance is free. Travel awards are available. Applications for travel awards are due April 15.

The Summer School is a four-day educational and training program for undergraduate and graduate students, postdoctoral and other trainees, as well as early-career professionals. The program offers separate tracks for toxicology and biomedical science, each featuring specific applications of current innovative non-animal methods. Attendees will benefit from career development workshops, poster presentations, laboratory tours and demonstrations, networking opportunities, and scientific talks from experts.

EURL ECVAM is seeing members for the EURL ECVAM Scientific Advisory Committee (ESAC). Interested individuals should apply by May 1.

The main tasks of ESAC are to:

• Assess the scientific validity of alternative methods/approaches intended for a given purpose.
• Advise on other scientific matters related to the work of EURL ECVAM and the protection of animals used for scientific purposes.
• Share its knowledge and experience on alternative methods/approaches used in science.

ESAC is made up of nine experts that serve for terms of five years that can be renewed. Plenary meetings of the committee are typically held once or twice per year; sub-groups focused on a particular topic may meet more often.

The Computational Toxicology Specialty Section of the Society of Toxicology will present a webinar on “The Predictive Toxicogenomics Space (PTGS) Modeling Tool Captures Diverse Cellular and Organ Toxicity Mechanisms and Serves for In Vitro Model-Driven Prediction of Drug-Induced Liver Injury.” The webinar will be held April 27 from 11:00 a.m.-noon EDT.

Speakers Roland Grafstrom and Pekka Kohonen of the Karolinska Institutet will describe an artificial intelligence-derived 14-gene component-based predictive toxicogenomics space tool that generates toxicity estimates based on omics data providing broad coverage of toxicity reactions and mechanisms. The tool enables application of in vitro data to assess tissue injury in multiple organs of experimental animals subjected to repeated-dose toxicity bioassays, including the accurate prediction of human drug-induced liver injury.
