Presentations from the September 19-20 meeting of the Scientific Advisory Committee on Alternative Toxicological Methods (SACATM) are available on the NTP website at (click “Presentations” in far right column under “Meetings”).

In presentations at the meeting, scientists from NICEATM, ICCVAM member agencies, and collaborators described advances in alternatives to animal use. SACATM members expressed support for the current activities and direction of ICCVAM and noted the progress that has been made in advancing alternatives to animal testing.

Discussions on the use of computational methods focused on the limitations and applications of machine learning models in predicting toxicology. Considering the potential uses of microphysiological systems (also known as “tissue chips”) in predicting human toxicity, committee members suggested these might be most useful for early-stage toxicity screening, evaluating effects on diverse populations, and providing models for applications lacking established animal models. They cautioned, however, that the context of use for these platforms need to be clearly defined, and expressed support for developing a roadmap to build confidence in specific applications.

SACATM meets annually to advise NICEATM, ICCVAM, and the director of the National Institute of Environmental Health Sciences regarding statutorily mandated duties of ICCVAM and activities of NICEATM.
