For decades, the use of animals in scientific research has been a subject of ethical debate. Now, a confluence of factors – growing ethical concerns, advancements in technology, and regulatory changes – is driving a global movement to phase out animal testing. Governments and researchers are embracing 'new approach methodologies' (NAMs) that promise more accurate, human-relevant results, including organs-on-chips, 3D tissue cultures (organoids), and sophisticated computational models powered by artificial intelligence (AI).

Why it matters

While animal models have been instrumental in scientific progress, they have inherent limitations. Differences in physiology and genetics between animals and humans often lead to inaccurate predictions, highlighting the need for more human-relevant testing methods. The shift towards humane science is gaining momentum, as technology continues to advance and regulatory frameworks evolve.

The details

The UK government has unveiled a comprehensive strategy to accelerate the transition away from animal testing, including ending regulatory testing on animals for skin and eye irritation by the end of 2026 and reducing the use of dogs and non-human primates in drug testing by at least 35% by 2030. Other regions, such as the US and Europe, are also taking steps to reduce animal use in research, with the FDA aiming to make animal studies the 'exception rather than the norm' within 3-5 years. Innovative technologies like organs-on-chips, organoids, and AI-powered computational models are proving to be as good as, or even better than, animal models at predicting human responses.

  • In 2006, the number of biomedical publications utilizing only NAMs was around 25,000.
  • By 2022, the number of biomedical publications utilizing only NAMs had surged to over 100,000.
  • The UK government unveiled its comprehensive strategy to accelerate the transition away from animal testing in November 2026.
  • The UK government aims to end regulatory testing on animals for skin and eye irritation by the end of 2026.
  • The UK government aims to reduce the use of dogs and non-human primates in drug testing by at least 35% by 2030.
