The pharmaceutical industry is witnessing a transformative shift as artificial intelligence (AI) becomes increasingly integrated into drug safety monitoring and pharmacovigilance (PV) processes. In 2024 and early 2025, major regulatory bodies including the European Medicines Agency (EMA), the U.S. Food and Drug Administration (FDA), and the International Council for Harmonisation (ICH) have released comprehensive guidelines addressing AI implementation in pharmacovigilance systems.

These developments represent a critical milestone for pharmaceutical companies, regulatory professionals, and safety experts who are navigating the complex landscape of AI-driven drug safety monitoring. As adverse event reporting volumes continue to surge and data complexity increases, AI technologies promise to enhance signal detection, automate case processing, and improve overall pharmacovigilance efficiency.

This blog provides a comprehensive overview of the latest regulatory guidance from these key authorities, examining how AI is reshaping pharmacovigilance practices and what pharmaceutical industry professionals need to know to ensure compliance while maximizing the benefits of these powerful technologies.

2. Current Regulatory Landscape for AI in Pharmacovigilance

2.1 EMA’s Strategic Approach to AI Implementation

The European Medicines Agency has taken a proactive stance on AI integration within pharmacovigilance systems. In March 2024, the EMA introduced the Scientific Explorer, an AI-enabled knowledge mining tool designed to help EU regulators conduct focused searches of regulatory scientific information. This tool represents a concrete example of how the agency is leveraging AI to improve data efficiency and decision-making processes.

The EMA’s artificial intelligence workplan, outlined in their strategic framework, emphasizes the need for robust validation, transparency, and continuous monitoring of AI systems throughout the medicinal product lifecycle. The agency has established clear expectations that marketing authorization applicants and holders must implement mechanisms ensuring AI and machine learning systems are transparent, accessible, validated, and continuously monitored.

Key aspects of EMA’s approach include:

• Risk-based assessment frameworks for AI system validation
• Transparency requirements for AI algorithms used in safety monitoring
• Continuous monitoring protocols for AI performance in real-world applications
• Integration with existing pharmacovigilance systems to maintain regulatory compliance

2.2 FDA’s Comprehensive AI Guidance Framework

In January 2025, the FDA released its draft guidance document titled “Considerations for the Use of Artificial Intelligence To Support Regulatory Decision-Making for Drug and Biological Products.” This guidance provides a risk-based credibility assessment framework specifically designed for evaluating AI models used in regulatory submissions.

The FDA’s approach centers on establishing credibility assessments that consider the context of use (COU) for specific AI applications. This framework is particularly relevant for pharmacovigilance applications where AI systems are used to:

1. Process individual case safety reports (ICSRs) and extract relevant safety information
2. Detect safety signals from large datasets including spontaneous reporting systems
3. Support regulatory decision-making through enhanced data analysis capabilities
4. Automate routine pharmacovigilance tasks while maintaining human oversight

The FDA emphasizes that sponsors must demonstrate the reliability, validity, and clinical relevance of AI systems before implementation in safety-critical applications. This includes comprehensive validation studies, ongoing performance monitoring, and clear documentation of AI system limitations.

2.3 ICH and International Harmonization Efforts

While the ICH has not yet released specific guidelines dedicated to AI in pharmacovigilance, the organization is actively working on harmonizing international approaches to AI regulation in pharmaceutical development and safety monitoring. The ICH’s current focus areas include:

• Standardization of AI validation methodologies across international regulatory jurisdictions
• Development of common terminology for AI applications in pharmacovigilance
• Harmonization of data quality requirements for AI system training and validation
• Cross-border collaboration frameworks for AI-driven safety signal sharing

The Council for International Organizations of Medical Sciences (CIOMS) has also contributed to this landscape through its Working Group XIV report on artificial intelligence in pharmacovigilance, which is currently under public consultation through June 2025.

3. Key AI Applications in Modern Pharmacovigilance
