OPERA v2.0 can be downloaded from the NIEHS Github repository.
CATMoS is the result of a global collaboration to develop in silico models to predict acute oral toxicity. It is a suite of consensus models developed by combining the results of individual models contributed by participants in the April 2018 Workshop on Predictive Models for Acute Oral Systemic Toxicity (Kleinstreuer et al. 2018). The individual models were built using information on chemical structures and rat oral acute toxicity data for nearly 9000 chemicals, and tested using approximately 3000 chemicals.
CATMoS includes models for predicting five acute oral toxicity endpoints: very toxic, non-toxic, U.S. Environmental Protection Agency hazard classification, United Nations Globally Harmonized System of Classification and Labelling of Chemical (GHS) hazard classification, and LD50. Predictions generated by CATMoS may be useful to those developing or triaging new chemicals or for prioritizing existing chemicals for more detailed and rigorous toxicity assessments.

Exemptions Help Reduce Live Animal Use in Leptospira Vaccine Potency Testing
Leptospirosis is a transmissible bacterial disease of animals and humans caused by infection with any of the pathogenic members of the genus Leptospira. The organism is shed in the urine and milk of infected animals and may cause symptoms of renal and hepatic disease, which could be fatal. Disease transmission to man and animals is reduced by the vaccination of cattle, swine, and dogs. In light of this, the potency of these vaccines must be tested by law.
In April 2017, the U.S. Department of Agriculture–Animal and Plant Health Inspection Service–Center for Veterinary Biologics (USDA-APHIS-CVB) issued CVB Notice 17-06, “Option to Remove Back-titration Hamsters from In Vivo Potency Tests for Leptospira Serogroups Pomona and Grippotyphosa.” This notice permits the removal of back-titration hamsters when potency testing vaccines containing L. pomona and L. grippotyphosa in accordance with 9 CFR 113 §101-104. This exemption to the codified test can reduce animal use up to 50% for these serogroups. CVB Notice 17-06 along with the 2015 CVB Notice 15-13, “Option to Remove Back-titration Hamsters from In Vivo Potency Tests for Leptospira Serogroups Canicola and Icterohaemorrhagiae” are available on the USDA-APHIS website.
CVB Notice 17-06 is the latest action in a continuing effort by USDA, an ICCVAM member, to reduce the number of hamsters required for potency testing of leptospirosis vaccines. In 2013, APHIS issued Veterinary Services Memorandum No. 800.102, which permitted the use of the in vitro ELISA test developed by CVB as a complete alternative to live animal usage required under 9 CFR 113 §101-104. CVB provides supplemental assay methods for in vitro testing using the ELISA test. All of these documents are available on the NICEATM website.
Small Business Phase II Grants for Alternative Methods Development
The National Institute of Environmental Health Sciences is funding grants to U.S. small businesses for development of medium- to high-throughput assays. Assays developed under these grants should evaluate the effects of toxicants on pluripotent or induced pluripotent cells with respect to cell differentiation and the resulting differentiated cell populations. The ability to incorporate genetic diversity in these assays would be useful. Results from these assays should help identify mechanisms of chemically induced biological activity, prioritize chemicals for more extensive toxicological evaluation, and support more predictive models of in vivo biological response.
Letters of intent for this funding opportunity are due September 4, with applications due October 4.
Full funding announcement on NIH website (posted June 23)

Voluntary Pilot Program to Reduce Animal Testing
On December 20, 2016, the U.S. Environmental Protection Agency launched a voluntary pilot program to evaluate the usefulness and acceptability of a mathematical tool that estimates the toxicological classification of a chemical, and published guidance on how pesticide companies can submit data for the program. This program is another step toward EPA’s goal of reducing animal testing by adopting better testing methods, as described in the March 2016 Letter to Stakeholders issued by Office of Pesticide Programs Director Jack Housenger.
The mathematical tool, known as the GHS Mixtures Equation, is used in the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Use of the GHS Mixtures Equation can reduce animal use for oral and inhalation toxicity studies of pesticide formulations.
To evaluate the GHS Mixtures Equation, EPA requests submission of acute oral and acute inhalation toxicity study data paired with mathematical calculations (GHS Mixtures Equation data) to support the evaluation of pesticide product formulations. EPA expects that the pilot will run for approximately six months but will begin data analysis sooner if enough data is received.

Translation of this research to the ISS-NL promises to accelerate the discovery of molecular mechanisms that underlie a range of common human disorders and advance understanding of therapeutic targets and treatments in a reduced fluid shear, microgravity environment that recapitulates cellular and tissue matrices of Earth.
NCATS has published a notice of intent to publish a funding opportunity for this initiative. Grant applications are not currently being solicited, but interested investigators are encouraged to begin developing meaningful collaborations and responsive projects.
Comments Requested on Proposed Amendments to GLP
A Proposed Rule published by the U.S. Food and Drug Administration (FDA) in the August 24 Federal Register describes amendments to the regulations for good laboratory practice (GLP) for nonclinical laboratory studies. The new amendments will require a complete quality system approach, referred to as a GLP Quality System, when safety and toxicity studies support or are intended to support applications or submissions for products regulated by FDA. FDA is proposing additional management responsibilities and standard operating procedures consistent with the proposed requirement for a GLP Quality System. In addition, the testing facility definition will be revised to reflect current practices for the conduct of nonclinical laboratory studies, particularly multisite studies. These proposals are intended to build quality into planning, conducting, and reporting a nonclinical laboratory study and to help ensure data quality and integrity. Comments on the Proposed Rule are due by November 22.
Workshop Report on Carcinogenicity of Mixtures Now Available
An August 2015 workshop sponsored by the National Institute of Environmental Health Sciences evaluated the scientific support for the Low-Dose Mixture Hypothesis of Carcinogenesis and developed a research agenda. A report from this workshop is now available on the Environmental Health Perspectives website. NICEATM Deputy Director Nicole Kleinstreuer, Ph.D., was a breakout group moderator and co-authored the report.
The Low-Dose Mixture Hypothesis of Carcinogenesis suggests that ongoing low-dose exposures to mixtures of commonly encountered environmental chemicals can produce effects in concert that promote carcinogenesis. The workshop report describes the science that supports this novel theory, identifies knowledge gaps, recommends future methodologies, and explores preventative risk assessment and policy decision making that incorporates cancer biology, environmental health science, translational toxicology, and clinical epidemiology. The workshop participants concluded that the theoretical merits of the Low-Dose Carcinogenesis Hypothesis are well founded with clear biological relevance and the premise warrants further investigation.
TSCA Reform Bill Becomes Law, Will Promote Use of Alternatives
A bill signed into law June 22 by President Obama updates the Toxic Substances Control Act (TSCA). The Frank R. Lautenberg Chemical Safety for the 21st Century Act (H.R. 2576) provides the Environmental Protection Agency (EPA) with the authority and a consistent source of funding to evaluate chemicals on the basis of health risks. The new law also includes language that requires EPA to develop a plan to promote the use of alternative methods that reduce, refine, or replace vertebrate animal testing and include in that plan a list of acceptable alternative methods. The highlights of the Lautenberg Chemical Safety Act were outlined in a blog post by EPA Administrator Gina McCarthy.
FDA Issues Final Guidance and Presents Webinar on Biological Evaluation of Medical Devices
The Food and Drug Administration (FDA) has issued a final guidance document on the use of International Standard ISO 10993-1, “Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process.” FDA developed the guidance document to assist industry in preparing applications and notifications on medical devices so that the devices are appropriately evaluated for the potential for adverse reactions.
FDA will present a webinar on the new guidance on July 21 at 1:00 p.m. Eastern Daylight Time. The webinar is open to the public and there is no charge to view.
EPA Releases Training Videos on Data Requirements for Antimicrobials
EPA is releasing five training videos providing guidance on EPA’s 40 CFR Part 158W data requirements for antimicrobial pesticides. These training videos will help the public and the pesticide industry better understand the pesticide registration process and make the process more efficient and transparent. The videos include the 2013 amendments to the data requirements that were made to ensure pesticide risk management decisions are founded on the best available sound science.
Additional videos will be released in the future as they become available. The videos are available on the EPA website.
New Guidance for Testing Pesticides Will Reduce Animal Testing
In a March 17 press release, EPA announced the publication of two guidance documents and initiation of a pilot program, all of which will support its goal to significantly reduce animal use for acute effects testing.
“Process for Establishing & Implementing Alternative Approaches to Traditional In Vivo Acute Toxicity Studies for FIFRA Regulatory Use” describes a transparent, stepwise process for evaluating and implementing alternative methods for the “six-pack studies,” which test for acute oral, dermal, and inhalation toxicity; skin and eye irritation; and skin sensitization. The document includes discussion of three major phases of the evaluation and implementation process, as well as the implications for reporting information required by the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). Establishment of this process and the clear articulation of the related reporting requirements address challenges associated with adopting alternative methods.
EPA is also requesting comment on draft guidance titled “Retrospective Analysis & Guidance for Waiving Acute Dermal Toxicity Tests for Pesticide Formulations.” This guidance document provides a rationale for waiving all acute dermal toxicity studies for pesticide formulations, and includes a data analysis conducted by the EPA Office of Pesticide Products (OPP) and NICEATM in support of this rationale. EPA is accepting comments on the guidance document until May 16.
Availability of the two documents was announced in an open letter to stakeholders from OPP Director Jack Housenger, who also announced a pilot program to evaluate alternative approaches to classify the toxicity of mixtures. Under the GHS Mixtures Equation Pilot, OPP will accept submission of oral and inhalation toxicity data paired with calculations done in accordance with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) to support the evaluation of pesticide product formulations.

The notice describes an exemption from the titration requirement in vaccination-challenge potency assays for Leptospira Serogroups Canicola and Icterohaemorrhagiae. Removal of the back-titration hamsters could reduce animal use by 50% for potency testing on these two fractions. The policy is effective Oct. 8. CVB Notice 15-13 is available on the USDA website.
Database of Rodent Uterotrophic Bioactivity Now Available
An article published October 2 as an advance publication in Environmental Health Perspectives describes curation and evaluation of a database of rodent uterotrophic bioactivity. The uterotrophic assay is a widely accepted in vivo test for identifying chemicals with potential estrogen receptor agonist activity.
The new database, which includes data from studies that adhere to six criteria specified in accepted regulatory test guidelines, is being proposed as a resource both for understanding in vivo outcome variability and for evaluating performance of in vitro alternative assays that measure estrogenic activity. For example, the database was used to validate an approach that could use high-throughput assays and computational methods to replace the uterotrophic assay in the U.S. Environmental Protection Agency’s (EPA’s) Endocrine Disruptor Screening Program (see article in the August Environmental Factor).

Version 2 of S1500+ Human Gene Set Now Available
NIEHS and National Toxicology Program scientists along with Tox21 partners have developed a list of environmentally responsive genes to be used in toxicogenomics approaches to screening large numbers of chemicals. Genes on the list were identified through both bioinformatics approaches and experimental data establishing certain genes’ importance to responses to toxicity. The recently updated “S1500+” gene list contains approximately 2750 genes that will be used to evaluate transcriptional changes in human cells or tissues in response to chemical exposure. These genes may also be useful for biomarker development and basic research efforts.
Nature Biotechnology Paper Reports Results of Crowdsourcing Challenge
An international study published in Nature Biotechnology presents the combined results of a crowdsourcing initiative to test how well the effects of a toxic compound can be predicted in different people. The study shows that computational methods can be used to predict some toxic effects on populations, although they are not yet sensitive enough to predict such effects in individuals. It also presents algorithms useful for environmental risk assessment.
The community-based challenge, known as the DREAM Toxicogenetics Collaboration, was led and organized by scientists from NIEHS, EMBL-EBI, Sage Bionetworks, IBM, the University of North Carolina, and the NIH’s National Center for Advancing Translational Sciences. Hundreds of computational biologists from all over the world tried their hand at predicting the toxicities of environmental compounds that had potential adverse health effects. One key benefit of the study is that it offers new methodologies for improvements in some areas of hazard evaluation and assessment.

NTP Requests Comments on Human "S1500" Gene Set
NTP requests comments on a set of human genes that have been identified and prioritized as environmentally responsive genes. This set of approximately 1500 "sentinel" genes was developed with input from the scientific community, to be used in toxicogenomics studies to screen human cells or tissues against large numbers of chemicals and evaluate transcriptional changes in response to chemical exposures. The goal is to develop a gene set that (1) is representative of highly diverse gene expression changes reported to date, (2) is capable of predicting the gene expression changes observed across the transcriptome, and (3) covers all major biological pathways.
The current version of the human S1500 gene set can be found on the NTP website. This site will be updated as changes to the list are made. The consensus strategy for selection of an appropriate sentinel gene set can be accessed at the same site. Comments on the gene set should be submitted as Microsoft Word or Excel files to Genelist@niehs.nih.gov by May 15.
