The National Institute of Standards and Technology has joined ICCVAM. NIST participation will provide ICCVAM with interest and experience in the study of process controls, measurement artifacts, and interlaboratory testing.
ICCVAM was established to facilitate and promote development and regulatory acceptance of new toxicological tests with the potential to replace, reduce, or refine animal use. The expertise within NIST will benefit ICCVAM, especially in the development of validation studies to assess the appropriateness of new test methods for specific purposes. In particular, NIST has experience with cell-based and small model organism assays, which are becoming increasingly important as alternatives for traditional animal tests. NIST also brings to ICCVAM additional expertise in experimental design and statistical analysis.
This event represents the first time ICCVAM has expanded its membership to include a new member agency since its inception in 2000. NIST, which is part of the U.S. Department of Commerce, has been interacting with ICCVAM since 2015. The agency submitted an official request to join ICCVAM in January 2017, which was approved in February by National Institute of Environmental Health Sciences Director Linda Birnbaum.
NICEATM and ICCVAM will be participating in two exhibitor-hosted sessions.
In other SOT activities, ICCVAM representatives will serve as co-chairs for five platform sessions, NICEATM scientists are co-authors on 10 poster or platform presentations, and ICCVAM members are co-authors on 18 presentations. Visit the NICEATM webpage summarizing SOT 2017 activities.
A NICEATM webinar series on “Using Informatics to Improve Data Analysis of Chemical Screening Assays Conducted in Zebrafish” begins on February 2. This three-part webinar series will consider the issues of protocol variability in zebrafish screening studies and how some of these issues might be addressed by implementation of standardized nomenclature systems.
The webinars are free and open to the public, although registration is required to attend. The webinar series is being organized by NICEATM in support of the National Toxicology Program’s Systematic Evaluation of the Application of Zebrafish in Toxicology (SEAZIT) program. A link to registration, details about all webinars, and more information about SEAZIT can be found on the NICEATM website.
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.
