Retha Newbold about CLARITY BPA

By the Collaborative on Health and the Environment

Retha Newbold discussed the program called The Consortium Linking Academic and Regulatory Insights on the Toxicity of Bisphenol A (CLARITY-BPA).

On this call Retha Newbold, MS, Researcher Emeritus, National Toxicology Program, National Institute of Environmental Health Sciences, discussed the program called “The Consortium Linking Academic and Regulatory Insights on the Toxicity of Bisphenol A (CLARITY-BPA)” which is an interagency agreement, conducted under the auspices of the National Toxicology Program (NTP), between The National Institute of Environmental Health Sciences (NIEHS) supported grantees, the staff of the Division of the National Toxicology Program (DNTP) at NIH/NIEHS, and the Food and Drug Administration at the National Center for Toxicological Research (FDA/NCTR). The goals of the consortium are to enhance the utility of a perinatal 2-year GLP chronic toxicity study on BPA for regulatory decision-making by incorporating a wide range of doses and some additional disease-related endpoints that are not usually covered.

To this end, 12 NIEHS grantees are studying hypothesis-driven mechanisms by investigating specific endpoints that maybe altered by BPA including behavioral/neuroendocrine, immune function, cardiac, reproductive tract, cancer, thyroid, and other organ systems. This consortium is unique in that it combines the knowledge and skills of the NTP staff with experts from the academic field who are covering more mechanistic studies. Although this program focuses on BPA, it may provide an example of how to better study effects of other endocrine disrupting chemicals especially since numerous organ systems may be involved.
