Start Preamble


The National Toxicology Program (NTP) Interagency Center for the Evaluation of Alternative Toxicological Methods (NICEATM) announces the workshop “Alternative Approaches for Identifying Acute Systemic Toxicity: Moving from Research to Regulatory Testing.” Workshop attendees will discuss the state of the science of alternative approaches for identifying acute systemic toxicity and explore ways to facilitate their implementation.


Meeting: September 24-25, 2015, from 9:00 a.m. to approximately 5:00 p.m. Eastern Daylight Time (EDT).

Meeting Registration: Deadline is September 11, 2015.


Meeting Location: Porter Neuroscience Conference Center, National Institutes of Health, Bethesda, MD 20892.

Acute systemic toxicity tests, which evaluate the propensity of a substance to produce lethality when administered orally, dermally, or by inhalation, are the most commonly performed type of safety test worldwide. This workshop will explore and discuss alternative approaches that could replace, reduce, or refine the use of animals for identifying chemicals that may cause acute systemic toxicity.

During the workshop, participants will (1) review the regulatory guidelines to define when and how acute systemic toxicity data are used; (2) review the science of alternative approaches for identifying acute systemic toxicity, including mechanism-based models, in vitro and in silico approaches, and lower vertebrate and invertebrate models; and (3) identify mechanisms of acute toxicity for promoting development of adverse outcome pathways (AOPs) for acute toxicity. The workshop steering committee is comprised of members from government and nongovernment stakeholder organizations including NICEATM, Physicians Committee for Responsible Medicine, People for the Ethical Treatment of Animals International Science Consortium Ltd., The Dow Chemical Company, U.S. Environmental Protection Agency, and Rutgers University.

Background Information on NICEATM

NICEATM conducts data analyses, workshops, independent validation studies, and other activities to assess new, revised, and alternative test methods and strategies. NICEATM also provides support for the Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM). The ICCVAM Authorization Act of 2000 (42 U.S.C. 285 l-3) provides authority for ICCVAM and NICEATM in the development of alternative test methods. Information about NICEATM and ICCVAM is found at​go/​niceatm and​go/​iccvam, respectively.
