Videos are now available from presentations from the 11th Annual 3Rs Symposium held September 4-5. Topics discussed included microphysiological systems, animal/organ sharing, optimizing animal breeding, and research design and statistical strategies. Videos are available on the National Agricultural Library, Animal Welfare Information Center’s website.

The 3Rs Symposium is an annual event organized by:

• Center for Alternatives to Animal Testing, Johns Hopkins University
• Bloomberg School of Public Health Department of Molecular and Comparative Pathobiology, Johns Hopkins University School of Medicine
• USDA Animal Welfare Information Center at the National Agricultural Library
• NIH Office of Laboratory Animal Welfare

Materials from previous 3Rs Symposiums are available on the Animal Welfare Information Center’s website.

A colloquium on “Emerging Concepts in Hazard Identification and Exposure Assessment of Per- and Polyfluoroalkyl Substances” will be held Tuesday, December 3 from 9:00-12:45 p.m. Speakers from federal agencies, academia, and testing laboratories will discuss dietary sources of PFAS and methods for assessing and communicating their health risks. The webcast is open to the public at no charge.

This is the latest event in a series organized by the Society of Toxicology and the FDA Human Foods Program (formerly the Center for Food Safety and Applied Nutrition). The colloquia present scientific information that is high-quality, cutting-edge, future-oriented toxicological science to provide a well-grounded foundation to inform the work of FDA employees. 

The National Eye Institute is leading an NIH collaboration to incentivize the creation, development, and validation of a quantitative data sharing index. The Data Sharing Index (S-index) Challenge aims to incentivize and reward effective data sharing practices by assessing how effective a researcher is in sharing their data in a way that has utility for future study. This metric will incorporate factors such as adherence to findable, accessible, interoperable, and reusable (FAIR) standards; data timeliness; completeness of annotation; frequency of utilization in other studies; and related publications and patents. This metric seeks to recognize and incentivize the efforts of individuals and teams in sharing data, rather than just the value of the data itself.

Phase 1 of the Challenge will open in April 2025; the deadline to register to participate is March 3, 2025. In Phase 1, participants will engage in brainstorming and idea generation, culminating in the submission of a proof-of-concept proposal. These proposals will compete in the first round, with up to six finalists selected to receive a $15,000 prize and advance to Phase 2. The Challenge will award up to $1M to support development of winning submissions. 

A webinar on "Microphysiological Systems (MPS) for Chemical Risk Assessment" is scheduled for October 28 from 10:00 a.m.-12:00 p.m. (ET), and is cohosted by the Johns Hopkins Center for Alternatives to Animal Testing, FDA Human Foods Program, and the International MPS Society. The focus of the webinar is on advancing applications of microphysiological systems (MPS) in chemical risk assessment and safety testing. The event will bring together regulators and researchers to explore the role of MPS in various research and regulatory settings, offering attendees the opportunity to engage with practical experiences and technical knowledge that drive innovation in this field. The webinar will be the first in a series aimed at fostering collaboration between leading investigators and regulators, providing a platform for exploring both established and potential applications of in vitro methods in chemical safety.

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. 

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

Investigators with expertise and insights into the area of NAMs are encouraged to consider applying for these funding opportunities, which will support Technology Development Centers and a Data Hub and Coordinating Center. NIH also encourages collaborative investigations combining expertise in in vitro, in silico, and in chemico NAMs. NIH expects to offer four or five awards with funding of approximately $18M per year.

• First estimated application due date for the Technology Development Centers (UM1 Clinical Trial Option) is February 28, 2025.
• First estimated application due date for the Data Hub and Coordinating Center (U24 Clinical Trial Option) is March 10, 2025.

Complement-ARIE program goals include:

• To better model and understand human health and disease outcomes across diverse populations.
• To develop NAMs that provide insight into specific biological processes or disease states.
• To validate mature NAMs to support regulatory use and standardization.
• To complement traditional models and make biomedical research more efficient and effective.

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.

• EPA’s next Computational Toxicology and Exposure Communities of Practice webinar will focus on “Using Environmental RNA to Understand the Effects of Pollution on Aquatic Ecosystems.” The webinar is on Thursday, September 26, at 11:00 a.m. EDT. Marissa Geroux of the Center for Environmental Measurement and Modeling will explain what environmental RNA (eRNA) is and how is it used in environmental science, and discuss use of eRNA metabarcoding to assess the impacts of emerging contaminants on aquatic communities. Information about the Communities of Practice webinar series and a link to register for this webinar are available.
• EPA is hosting its fourth “Conference on the State of Science on Development and Use of NAMs for Chemical Safety Testing” on November 5-6. This will be a hybrid meeting with in-person participation on EPA’s campus at Research Triangle Park, NC. Registration to attend in person is open until October 22 or until the venue capacity is reached. Information and a link to register are available.
• EPA has released updates of the Sequence Alignment to Predict Across Species Susceptibility (SeqAPASS) and Generalized Read-Across (GenRA) tools. These and other EPA CompTox tools are available on the EPA CompTox website.

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 National Institutes of Health (NIH) has published its landscape analysis for the Complement Animal Research in Experimentation (Complement-ARIE) program.

Complement-ARIE will accelerate the development, standardization, validation, and use of human-based NAMs that more accurately model human biology, and complement, or in some cases, replace traditional research models. To ensure the Complement-ARIE program focused on the best opportunities and areas of greatest need for human-based model development, a comprehensive landscape analysis was conducted to collect information on ongoing efforts in the NAMs space. The analysis described existing efforts, and highlighted gaps, challenges, and opportunities in the areas of human-based models of health and disease including:

• In vitro models
• In silico models
• In chemico cell-free models
• FAIRness of data needed to train, interpret, and use NAMs (FAIR = findable, accessible, interoperable, reusable)

NICEATM scientists were key contributors to the landscape analysis. In addition to NICEATM Director Nicole Kleinstreuer, seven members of the Inotiv contract support team are acknowledged as authors of the landscape analysis report.

The National Institutes of Health (NIH) Common Fund has announced a Notice of Intent to Publish a Funding Opportunity for the Complement Animal Research in Experimentation (Complement-ARIE) program.

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.

A new report, “In Silico Technologies: A Strategic Imperative for Accelerating Breakthroughs and Market Leadership for FDA-regulated Products,” has been published by the Reagan-Udall Foundation for the FDA.

The report urges the adoption of in silico technologies such as artificial intelligence and machine learning for development and safety evaluation of products that influence human health. This report strives to bridge the gap between technical and business teams in the ecosystem of products regulated by the U.S. Food and Drug Administration (FDA) and the nation’s food supply by building the business case for industry investment in in silico technologies as a strategic imperative for accelerating breakthroughs and market leadership in FDA-regulated products. NICEATM Director Nicole Kleinstreuer was a contributor to the report.

A new NTP webpage will allow users to easily search PubMed for information on specific topics related to alternatives to animal testing. NICEATM and the U.S. Department of Agriculture (USDA) National Agricultural Library’s Animal Welfare Information Center (AWIC) collaborated to develop search strategies, known as “hedges,” for topics specific to alternatives. Hedges are now available for the following topics:

• Alternatives to animal use for assessing acute inhalation toxicity.
• Alternatives to animal use for assessing developmental neurotoxicity.
• In vitro to in vivo extrapolation.
• Microphysiological systems.

Additional hedges are under development; please contact Catherine Sprankle with suggestions of additional topics.

AWIC has developed search hedges for a number of animal welfare topics, and offers guidance and assistance for literature searches on animal use alternatives. For more information and to access these resources, visit the USDA website.

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

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 would 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 scientific community to support development and use of NAMs. In her statement, Bertagnolli noted how the recommendations 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 new approach methodologies (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. The Complement-ARIE program 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.

Registration is open for upcoming workshops on “Meeting the Requirements of the Animal Welfare Act” offered by the USDA Animal Welfare Information Center. Live virtual workshops will be offered on Wednesday and Thursday, March 6-7, from 1:00-4:00 p.m. EST each day, and on Wednesday and Thursday, May 8-9, from 1:00-4:00 p.m. EDT each day. There is also a self-paced asynchronous version of the workshop available.

The Animal Welfare Information Center was established to help the regulated community comply with the Animal Welfare Act. The Center provides information on approaches to prevent duplication of animal experimentation and alternative methods that replace, reduce, or refine animal use. More information about the Center, including an introductory video, is available on the Center’s website.

The National Center for Biotechnology Information (NCBI) is hosting a codeathon on “Building Transparent ML/AI Solutions to Advance Biological Research.” The event will address the growing need for collaboration, knowledge sharing, and exploration of the transparent deployment of machine learning (ML) and artificial intelligence (AI) in research.

This event will bring together developers, data scientists, and tech enthusiasts to build equitable and transparent ML/AI solutions that tackle various problems in healthcare, research, education, and more. During the week-long codeathon, teams of 5-10 people will collaborate virtually to design and build innovative solutions that promote fairness, transparency, and accountability in AI/ML algorithms and models. Teams that want to leverage NCBI databases or publicly available scientific data for deep learning are encouraged to apply. Priority will be given to projects that make use of NCBI data and tools. At the end of the event, teams will present their work to each other, representatives from the National Institutes of Health (NIH), and the public. Team products will be made publicly available, and participants will be encouraged to co-author a joint manuscript and share their work online and at conferences.

In a January 2024 Federal Register notice, 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.
