Consumer Products and Therapeutics Program

Public Health Significance

The large number of consumer product chemicals that people are exposed to presents challenges for determining potential adverse human health outcomes. Some issues include the following:

  • Consumer products often are part of complex mixtures and frequently result in low-level, chronic daily exposures.
  • The pace of traditional, chemical-by-chemical toxicity testing methods is relatively slow in terms of gaining knowledge and informing public health decision making.

When it comes to therapeutics, unforeseen health effects may require additional toxicity testing to address potential concerns. For example, problems may arise for individuals exposed to human immunodeficiency virus therapies across the lifespan or during different life stages.

Program Objectives

The Consumer Products and Therapeutics (CPT) program in the NIEHS Division of the National Toxicology Program (DNTP) is structured around the following objectives:

  1. Apply class-based methodologies as a framework for assessing potential human health effects of chemicals in consumer products and consistently evaluate their effectiveness using existing toxicity data. This will guide and prioritize testing and further research strategies. The starting point will be a class-based assessment of organo-halogenated flame retardants, or OFRs (more on that below).
  2. Partner early with appropriate stakeholders (e.g., the National Institutes of Health Office of AIDS Research) to provide impactful scientific knowledge on therapeutics.
  3. Strengthen and build partnerships across federal agencies and nongovernmental organizations to contribute value-added research for both consumer products and therapeutics, to facilitate a broader dissemination of information and guide public health decisions.

Background

The CPT program provides a unique opportunity to inform research and decision making by strategically directing our efforts toward class-based approaches. Evaluating potential toxicities that can lead to human health effects from exposure to the vast number of chemicals present in consumer products is a critical public health goal.

  • For consumer products, the CPT program will use a chemical class assessment of OFRs as the exemplar, due to widespread human exposure to the substances and support from the U.S. Consumer Product Safety Commission. DNTP has a strong history of research on flame retardants that will support and inform the research.
  • DNTP will leverage a multidisciplinary approach that has the potential to support, influence, and produce cutting-edge data that could impact public health decisions. Data mining and literature scoping will lead to the development of evidence maps that can serves as a foundation for evidence-based decisions for analysis and downstream predictive toxicity testing by high-throughput computational methods and experimental assays.

For therapeutics, the CPT program has engaged key partners for discussions regarding compound evaluations or questions of mutual interest (e.g., discussions with the U.S. Food and Drug Administration on genotoxic impurities in drugs). Presently, the primary focus for therapeutics research within DNTP is the evaluation of HIV combination antiretroviral therapies across the lifespan or during different life stages to better understand potential treatment-associated comorbidities, coinfections, and complications.
