Presentations from Acute Toxicity Workshop Now Available

26 October 2015

« Presentations from the Sept. 24–25 workshop on « Alternative Approaches for Identifying Acute Systemic Toxicity: Moving from Research to Regulatory Testing » are now available below and on the NICEATM website.

At this workshop, representatives from regulatory agencies, academia, and industries developed strategies for advancing alternative methods for product safety testing that meet the needs of regulatory agencies. The workshop was co-organized by NICEATM, Physicians Committee for Responsible Medicine, and PETA International Science Consortium Ltd., and was held at the National Institutes of Health in Bethesda, Maryland.

Materials from the workshop are available below and on the NICEATM website. The workshop proceedings will be submitted for publication early next year.

Acute systemic toxicity tests are the most commonly performed type of safety test worldwide. At this workshop, over 60 representatives from regulatory agencies, academia and industry discussed the state of the science of alternatives to animal use for acute systemic toxicity testing and explored ways to facilitate their implementation.

Workshop attendees identified several resources as necessary for meaningful progress in identifying and implementing alternatives: high quality reference data, training on use and interpretation of computational approaches, and global harmonization of testing requirements. Attendees particularly noted the need to characterize variability in reference data being used to evaluate new approaches. NTP and NICEATM scientists plan to take a lead role in coordinating data collection from a number of sources identified during the workshop.

Workshop breakout groups explored different approaches to reducing or replacing animal use for acute toxicity testing, with each group crafting a roadmap and strategy for accomplishing this within a three-year timeframe. NICEATM will coordinate the creation of and provide support for a working group comprised of workshop participants that will be charged with implementing the strategies.

Proceedings from the workshop will be submitted for publication in early 2016. Presentations from the workshop are available below.

This workshop was cosponsored by NICEATM, the PETA International Science Consortium Ltd., and the Physicians Committee for Responsible Medicine. »
