Executive Summary
Periodic Safety Update Reports (PSURs) and Periodic Benefit-Risk Evaluation Reports (PBRERs) represent one of the most resource-intensive regulatory obligations in pharmacovigilance. A single PSUR can consume 3-6 months of pharmacovigilance team effort, requiring manual compilation of adverse event data from global safety databases, systematic literature review, signal evaluation, and comprehensive benefit-risk assessment.
ArcaScience's automation platform integrates data from global safety databases (FAERS, EudraVigilance, VigiBase), literature monitoring systems (PubMed, Embase), clinical trial registries, and real-world evidence sources to generate ICH E2C(R2)-compliant PSUR/PBRER documents in a fraction of the time. The platform maintains complete data traceability and regulatory audit trails while embedding quantitative benefit-risk analysis directly into each report section.
This technical guide walks through the architecture, methodology, and validation approach that enables regulatory-grade document generation with 75% reduction in preparation time, 100% ICH E2C(R2) section coverage, and seamless eCTD Module 2.7 formatting for direct regulatory submission.
Key Takeaways
ICH E2C(R2) Alignment
Every PSUR section—from executive summary through appendices—is mapped directly to ICH E2C(R2) regulatory requirements. Automated compliance checks ensure no required elements are missing before submission.
Automated Data Integration
Continuous ingestion from FAERS, EudraVigilance, VigiBase, company safety databases, and sponsor-specific data warehouses. Data is normalized, deduplicated, and harmonized to MedDRA terminology automatically.
Signal Detection Synthesis
Automated disproportionality analysis (PRR, ROR, MGPS, BCPNN) with AI-augmented signal evaluation. Generates signal narratives with complete supporting evidence tables and statistical workbooks.
Literature Monitoring
Continuous PubMed and Embase screening with AI-powered relevance scoring. Literature results are automatically extracted, categorized, and integrated into PSUR section narratives with full citation management.
Benefit-Risk Evaluation
Quantitative benefit-risk analysis embedded directly into the PSUR Integrated Benefit-Risk Analysis section. BRAT framework value trees, effects tables, and sensitivity analyses generated automatically.
Submission-Ready Output
Documents are formatted for eCTD Module 2.7 with automated table of contents, figure/table numbering, and cross-references. Direct export to regulatory portal submission formats (FDA Gateway, EMA Gateway).

Chapter 1: The PSUR/PBRER Regulatory Landscape
Periodic Safety Update Reports were introduced by the International Council for Harmonisation (ICH) in 1996 as a standardized format for post-approval safety reporting. The guideline underwent significant revision in 2012 with ICH E2C(R2), which reframed the document as a Periodic Benefit-Risk Evaluation Report (PBRER)—emphasizing not just adverse event cataloging, but comprehensive benefit-risk assessment.
The transition from PSUR to PBRER reflected a fundamental shift in regulatory thinking: safety signals must be evaluated in the context of therapeutic benefit, patient population characteristics, and availability of alternative treatments. This change increased both the scientific rigor and operational burden of periodic reporting.
A typical PSUR/PBRER for a marketed product requires:
- Manual review of 5,000-50,000 adverse event reports from global databases
- Systematic literature screening of 200-2,000 publications
- Signal detection analysis across multiple therapeutic areas and geographies
- Integration of clinical trial safety data, real-world evidence, and non-clinical findings
- Comprehensive benefit-risk narrative with quantitative or semi-quantitative analysis
- Preparation of 100-300 page documents with 20-50 appendices
This work typically consumes 3-6 months of effort from multidisciplinary teams including pharmacovigilance scientists, medical writers, statisticians, and medical reviewers. For companies with large portfolios, the resource burden can become unsustainable—particularly when combined with other pharmacovigilance obligations like Development Safety Update Reports (DSURs), Risk Management Plans (RMPs), and signal management activities.
The business case for automation: ArcaScience's platform enables 75% reduction in PSUR preparation time while improving consistency, reducing human error, and maintaining complete audit trails. This frees senior pharmacovigilance staff to focus on strategic signal evaluation and regulatory strategy rather than document assembly.
Chapter 3: Data Sources and Integration Architecture
Automated PSUR generation depends on robust, real-time data integration from multiple heterogeneous sources. ArcaScience's data pipeline ingests safety data from:
Global Safety Databases
- FDA FAERS: 15+ million adverse event reports, quarterly releases, normalized to MedDRA
- EMA EudraVigilance: 20+ million reports from EU member states, real-time access via EVDAS
- WHO VigiBase: 25+ million reports from 140+ countries, accessed via VigiLyze API
- PMDA (Japan), Health Canada, MHRA (UK): Regional databases integrated on rolling basis
- Sponsor safety databases: Oracle Argus, ArisGlobal LifeSphere, Veeva Vault SafetyDocs via HL7 ICSR feeds
Literature and Publication Sources
- PubMed/MEDLINE: 35+ million biomedical citations, daily updates via E-utilities API
- Embase: 40+ million records including conference abstracts, accessed via Elsevier API
- ClinicalTrials.gov: Trial results data for efficacy/safety comparison
- Regulatory agency communications: FDA Drug Safety Communications, EMA safety referrals
Data Harmonization Pipeline
Raw data from these sources undergoes a four-stage normalization process:
- Deduplication: Fuzzy matching on patient demographics, event dates, reporter information to identify duplicates across databases
- MedDRA standardization: All adverse events mapped to consistent MedDRA version (currently 26.0), with automatic updates when new versions release
- Data quality scoring: Completeness, recency, source reliability used to weight reports in signal detection
- Lineage tracking: Every data point maintains full provenance chain for regulatory audit trails
This architecture enables near-real-time PSUR data queries while maintaining the data integrity and traceability required for regulatory submissions. Chapter 3 includes detailed data flow diagrams, API specifications, and validation test cases used in platform development.
