Expert insight: The regulatory landscape for AI and automation is rapidly evolving. Surveys of pharma professionals show both growing interest in AI-assisted workflows and concerns about accuracy and traceability. A notable survey highlights that while AI-assisted reviews are increasingly explored, a majority remains cautious about automating the creation of regulatory filings without human oversight. This underscores the importance of choosing tools that offer robust audit trails, strong validation capabilities, and clear human-in-the-loop governance. (emarketer.com)

Why choose an AI-powered approach in 2026? A quick perspective

As the regulatory environment grows more complex—across the US, EU, and Asia—organizations increasingly rely on AI-assisted tooling to improve speed, consistency, and compliance. Real-time validation, regulatory intelligence, and automated drafting can significantly reduce cycle times and lower risk when paired with solid governance. However, AI systems must be implemented with explicit auditability, traceability, and validation against authoritative standards. The industry’s move toward AI-assisted submissions is supported by ongoing updates to regulatory validation criteria and gateway integrations, as demonstrated by vendors like EXTEDO and Veeva, and by regulatory bodies adapting to new submission formats.
