In the dynamic world of pharmaceuticals, timely and accurate reporting of drug safety data is essential. Aggregate reports—like Periodic Safety Update Reports (PSURs), Periodic Benefit-Risk Evaluation Reports (PBRERs), and Development Safety Update Reports (DSURs)—serve as critical tools to communicate drug safety trends and inform regulatory decision-making. Traditionally, these reports demand meticulous data collation, complex analysis, and expert interpretation, making them labor-intensive and time-consuming.
With the advent of Generative AI (Gen AI), a new era has begun. Gen AI models, particularly large language models (LLMs), are transforming the pharmacovigilance (PV) landscape by enhancing efficiency, accuracy, and consistency in aggregate reporting and data analysis. This blog explores how Gen AI is revolutionizing these essential processes in the pharmaceutical industry.
Understanding Aggregate Reporting in Pharma
Aggregate reporting refers to the process of compiling safety data across multiple sources—such as spontaneous reports, clinical trials, literature, and real-world evidence—over a defined period. These reports aim to:
Monitor the benefit-risk profile of a medicinal product
Identify new or changing safety signals
Provide a comprehensive overview of safety for regulators
Common aggregate reports include:
PSUR/PBRER: Focused on marketed products
DSUR: Related to investigational products in clinical development
Annual Safety Reports (ASRs): Submitted during ongoing clinical trials
Risk Management Plans (RMPs): Detailing risk mitigation strategies
Each report requires integrating large volumes of heterogeneous data, applying medical and regulatory reasoning, and delivering insights in a structured format.
The Challenges of Traditional Aggregate Reporting
Before diving into Gen AI’s contributions, it’s essential to understand the limitations of traditional methods:
Manual Data Extraction and ConsolidationSafety data comes from various sources—Individual Case Safety Reports (ICSRs), clinical trials, literature, registries—requiring significant manual effort for extraction and harmonization.
Time-Consuming Medical ReviewInterpreting trends in adverse events and their clinical relevance requires deep domain expertise and time-intensive review.
Complex Regulatory ComplianceRegulations across geographies (FDA, EMA, MHRA, PMDA, etc.) vary, making compliance a daunting task without automated cross-referencing and validation.
Error-Prone DocumentationManual compilation increases the risk of inconsistency, data duplication, and documentation errors, potentially leading to compliance issues.
Limited Real-Time AnalysisTraditional tools often lag in real-time signal detection, reducing proactive safety surveillance.
Enter Generative AI: Redefining the Landscape
Generative AI, particularly transformer-based language models like GPT-4, brings powerful language understanding, contextual reasoning, and data synthesis capabilities. Here's how Gen AI is transforming aggregate reporting and data analysis:
1. Automated Literature Review and Data Extraction
Gen AI can ingest and summarize vast volumes of medical literature and safety data automatically. By parsing structured and unstructured documents—including journal articles, ICSRs, and regulatory submissions—Gen AI significantly reduces the manual burden of data gathering.
Benefits:
Rapid identification of relevant studies or events
Summarization of key findings from literature
Extraction of adverse event frequencies, case narratives, and risk-benefit assessments
For instance, AI-powered tools can scan thousands of articles in minutes, flagging those with potential safety concerns and generating summaries for inclusion in reports.
2. Natural Language Summarization of Safety Trends
One of Gen AI’s core strengths is summarization. Whether it’s summarizing adverse event patterns, benefit-risk analyses, or cumulative case data, Gen AI generates human-like narratives based on structured inputs.
Use Cases:
Creating executive summaries or risk evaluation narratives in PBRERs
Drafting responses to regulatory queries based on data analysis
Highlighting trends and changes from previous reporting periods
This not only improves report consistency and clarity but also allows PV professionals to focus on strategic interpretation rather than manual drafting.
3. Data Harmonization Across Sources
Aggregate reports often pull data from multiple platforms—EudraVigilance, FAERS, VigiBase, internal safety databases, and more. Gen AI can normalize terminologies (e.g., MedDRA terms), deduplicate data, and align reporting formats.
Benefits:
Improved data integrity and consistency
Reduced manual reconciliation work
Seamless integration with signal detection tools
By using AI to unify data, organizations reduce silos and ensure that their reports reflect a single, cohesive safety narrative.
4. Real-Time Signal Detection and Trend Analysis
Generative AI combined with predictive models can enhance real-time monitoring of safety signals. Using continuous ingestion and analysis of incoming safety data, AI models can detect emerging patterns much earlier than traditional methods.
Applications:
Early identification of increased incidence rates
Prioritization of signals based on severity and frequency
Suggesting follow-up actions for potential risks
This capability allows regulatory and safety teams to be proactive, addressing concerns before they escalate.
5. Automating Drafting of Regulatory-Compliant Reports
Generative AI models trained on regulatory writing styles can produce first drafts of aggregate reports that comply with ICH guidelines. This includes structured sections such as:
Introduction and product overview
Worldwide marketing authorization status
Exposure data
Summary of significant findings
Benefit-risk evaluation
Impact:
60–80% reduction in drafting time
Enhanced uniformity across product reports
Lowered dependency on manual regulatory writing
AI-generated drafts can then be reviewed and refined by medical writers, saving substantial effort and cost.
6. Risk-Benefit Assessment and Visualization
Gen AI can not only describe but also visualize risk-benefit data using integrations with natural language-to-chart tools. This enables better understanding of:
Risk mitigation effectiveness
Comparative risk across regions or populations
Evolution of safety signals over time
Advantages:
Enhanced communication with regulators
Visual storytelling for safety trends
Support for internal decision-making and labeling updates
7. Multilingual Report Generation for Global Submissions
For global pharmaceutical companies, reporting often requires translations or localized versions of aggregate reports. Gen AI models with multilingual capabilities can generate drafts in multiple languages with context-specific accuracy.
Key Benefits:
Streamlined global regulatory submissions
Reduced translation costs and delays
Improved accessibility for non-English-speaking affiliates
Ensuring Accuracy, Compliance, and Human Oversight
While Gen AI brings immense value, it must operate within a framework of human oversight and regulatory compliance. AI-generated content should always be reviewed and validated by qualified professionals, especially in contexts involving clinical judgment or legal accountability.
Best Practices Include:
Establishing validation and audit trails for AI-generated outputs
Incorporating role-based access and review workflows
Training AI models on company-specific data and guidelines
Implementing bias detection and quality assurance mechanisms
Moreover, Gen AI should complement, not replace, human expertise—enhancing speed and scalability while leaving interpretation and decision-making to experienced professionals.
Real-World Impact: Pharma Companies Adopting Gen AI
Several leading pharmaceutical companies and CROs are already integrating Gen AI into their safety reporting workflows. Use cases include:
Automating PSUR draft creation using AI co-pilots

Using Gen AI to create data-driven responses for regulatory authority requests
Developing AI-assisted dashboards for cumulative safety review
The result is faster report cycles, improved quality, and cost savings, with some companies reporting up to 50% reduction in reporting timelines.
Future Outlook: What Lies Ahead?
As Gen AI technology matures, its integration with agentic AI systems will take automation even further—enabling autonomous agents to:
Continuously monitor data for changes
