Annex 22 is the European Medicines Agency's proposed framework for AI and machine learning systems used in GxP environments. It sets expectations for areas including model validation, intended use documentation, data quality and traceability, change control, explainability and human oversight. Final publication is expected in 2026, with implementation phased through 2027 and 2028.
In practical terms, organisations will need to demonstrate not only that an AI system performs as intended, but also that its outputs can be understood, monitored and appropriately governed throughout its lifecycle. Dynamic and adaptive models, including generative AI and large language models, remain subject to additional scrutiny in critical GMP applications while regulators continue to evaluate their use.
If you've spent your career building, validating or governing AI systems, much of what Annex 22 expects will feel surprisingly familiar.
Concepts such as model validation, version control, change management, performance monitoring and human oversight have been standard practice in mature AI environments for years. The difference is that, within life sciences, these disciplines are now becoming formal regulatory expectations rather than internal engineering standards. That shift is significant because it changes how organisations think about talent. Instead of looking only for professionals with pharmaceutical experience, many are searching for people who already understand how to develop and manage AI responsibly, then helping them apply those skills within a regulated environment.
For professionals considering a move into life sciences, this creates an interesting dynamic. Many of the technical capabilities employers are now prioritising already exist within mature technology organisations. The opportunity lies in learning how those capabilities are applied within a regulated healthcare environment, where decisions can directly influence product quality, regulatory compliance and, ultimately, patient safety.
That is what makes these roles different. The engineering principles are often familiar. The context in which they are applied is not.
