Regulatory Actions for Years 2. Question IV. A. 3: OSHA is considering greater reliance on peer- reviewed toxicological evaluations by other Federal agencies, such as NIOSH, EPA, ATSDR, NIEHS and NTP for hazard identification and dose- response analysis in the observed range. What advantages and disadvantages would result from this approach and could it be used in support of the PEL update process? Use of Systems Biology and Other Emerging Test Data in Risk Assessment Toxicity testing is undergoing transformation from an approach primarily based on pathological outcomes in experimental animal studies to a more predictive paradigm that characterizes critical molecular/cellular perturbations in toxicity pathways using in vitro test systems. The paradigm shift is being largely driven by the technological advances in molecular systems biology such as the use of high throughput screening (HTS) assays, new computational methods to predict chemical properties, and computer models able to associate molecular events with a biological response. The vision, strategies, and frameworks for applying the new toxicity data to risk- based decision making are laid out in landmark reports by the National Research Council (NRC, 2. Ex. #2. 4, NRC, 2. Ex. #2. 5). A collaborative Federal initiative known as ‘‘Tox. National Toxicology Program (NTP), the EPA Office of Research and Development, the NIH. Chemical Genomics Center (NCGC), and the Food and Drug Administration (FDA) to collaborate on development, validation, and translation of innovative HTS methods to characterize key steps in toxicity pathways (NTP, 2. Ex. #4. 0). Tox. 21 has already screened over a 1. HTS assays that have been made available to the scientific community through publically accessible databases (e. EPA ACTo. R, NTP CEBS). EPA has launched a program, known as ‘‘Nex. Gen’’, to implement the NRC vision and advance the next generation of risk assessment (EPA, 2. Ex. #4. 1). Nex. Gen is a partnership among EPA, NTP, NCGC, AND FDA, along with ATSDR and California’s EPA Office of Environmental Health Hazard Assessment. The objectives of Nex. Gen are to pilot the new NRC risk assessment framework, refine existing bioinformatics systems, and develop specific prototype health risk assessments. These objectives are expected to be achieved through an iterative development process that includes discussion with scientists, risk managers, and stakeholders. National Toxicology Program (NTP).
