CLARITY-BPA Program in Rats: Is It Translatable to Humans?

The Consortium Linking Academic and Regulatory Insights on BPA Toxicity (CLARITY-BPA) program was the most comprehensive study to date examining a full range of health effects of varying bisphenol A (BPA) exposure in rats. The major concern of the CLARITY-BPA program that has not previously been discussed is whether exposing rats to varying doses to BPA is translatable to humans, even at the "typical" exposure ranges for humans. This perspective will provide evidence that the vast majority of pharmaceutical drug development and other trials in animals have not been replicated in human randomized studies. Similarly, to truly understand whether BPA exposure affects human health, clinical trials are needed to examine BPA administration in humans in controlled settings.
