Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, with reference to the policy paper entitled Replacing animals in science: A strategy to support the development, validation and uptake of alternative methods, published on 11 November 2025, what progress has she made in collecting annual data on the number of clinical trial applications that include toxicity tests conducted in 2 species.

The delivery of the commitment to collect annual data on the number of clinical trial applications that include toxicity tests conducted in 2 species, sits with NC3Rs.

MHRA holds this data and NC3Rs are working with them on the best way to access and share this information. The strategy commits to first publish by mid-2026.

The Government will publish a delivery update, alongside key performance indicators on progress across all elements of the strategy, later in 2026.
