Reducing animal use in regulatory testing is crucial. Innovations like humane endpoints and noninvasive techniques show promise, but challenges like funding and defining distress remain.

Area of Science:

  • Toxicology
  • Animal Welfare Science
  • Regulatory Science

Background:

  • Regulatory testing, particularly in the US and Canada, significantly contributes to animal use in painful or distressing procedures.
  • There is a growing emphasis on refining (minimizing suffering) and reducing (decreasing numbers) animal use in these tests.

Purpose of the Study:

  • To review current approaches and challenges in refining and reducing animal use in regulatory testing.
  • To identify areas for improvement and future directions in animal welfare within regulatory science.

Main Methods:

  • Review of existing literature and practices in regulatory animal testing.
  • Analysis of traditional and novel strategies for refinement and reduction.
  • Discussion of technological advancements and international harmonization efforts.
Keywords:
Biomedical and Behavioral Research

Main Results:

  • Refinement strategies, such as humane endpoints, and reduction methods, including tier testing and improved experimental design, are being implemented.
  • Technological advancements (telemetry, noninvasive techniques) offer potential to decrease animal demand and suffering.
  • International harmonization and coordination are key to further reducing animal use.
  • Challenges persist, including limited research funding, differentiating distress from pain, and addressing the overuse of rodents.

Conclusions:

  • Despite challenges, significant potential exists for refining and reducing animal use in regulatory testing.
  • Continued research, technological innovation, and collaborative efforts are essential for advancing animal welfare in regulatory science.
