Pharmacovigilance automation — cutting ICSR & PSUR cycle times.

This guide separates regulatory process requirements from possible automation. The current source set is the EMA GVP collection, including Modules VI, VII and IX, together with the applicable ICH and local reporting rules. Confirm the current version and territory before implementation.

The two halves of pharmacovigilance

PV operations split cleanly into:

1. Case management. Intake, processing, coding, and reporting of individual case safety reports (ICSRs) — the per-event flow, governed by ICH E2B(R3) for case format and the GVP modules / FDA 21 CFR Part 314.80 / Part 600.80 for reporting timelines.

2. Aggregate analysis. Periodic Benefit-Risk Evaluation Reports (PBRERs / PSURs under ICH E2C(R2)), Periodic Adverse Drug Experience Reports (PADERs in the US), Risk Management Plans (RMPs), Development Safety Update Reports (DSURs under ICH E2F), Post-Authorisation Safety Studies (PASS).

The two halves overlap operationally — the same source data feeds both — but the regulatory artifact and the QPPV signature are different.

ICSR processing — where assistance can be tested

A representative ICSR cycle:

1. Intake (call center, email, portal, literature).
2. Triage (valid vs. invalid; serious vs. non-serious).
3. Data entry into safety database (ARGUS, ARISg, LSMV).
4. MedDRA coding of reactions and indications.
5. Narrative drafting.
6. Medical review and causality assessment.
7. QPPV / safety physician sign-off.
8. Reporting to authorities (EudraVigilance, FAERS, local FIUs) within timelines (Day 7 / Day 15 / non-expedited).

Steps 2–5 are where AI gives the biggest unlock without altering the regulator-facing artifact:

Triage automation

Classification can route likely non-cases for review and prioritise material that may meet minimum case criteria. Performance must be measured on representative data and monitored after change.

Where to be careful: the GVP requirement to attempt to obtain follow-up on incomplete cases applies to any case meeting minimum criteria. The triage filter has to err toward inclusion — false negatives (missing a genuine case) are worse than false positives.

MedDRA coding

MedDRA (Medical Dictionary for Regulatory Activities) coding of reaction terms is rules-based at heart but linguistically tricky. Free-text reaction descriptions ("a pounding feeling in the chest after eating") need mapping to a Lowest Level Term (LLT), which rolls up through Preferred Term (PT), High Level Term (HLT), High Level Group Term (HLGT), and System Organ Class (SOC).

AI can suggest LLTs and PTs, but match rate varies by language, product, source channel and case complexity. Validate against expert-coded ground truth, review disagreements, monitor dictionary-version changes and retain the final human decision.

Narrative drafting

Case narratives describe the patient, the suspect drug, the reaction, the temporal relationship, treatment, dechallenge, rechallenge, and outcome. Industry-standard narrative templates exist; LLMs are good at populating them from the structured case data.

The qualified-person review still happens. The reviewer checks completeness, chronology, clinical inference, consistency with structured fields and the final signed record.

Duplicate detection

Cases reported through multiple channels can describe the same event differently. Semantic similarity can add candidates to established matching rules; a validated decision process is still needed before records are merged or linked.

Aggregate reports — PSUR / PBRER drafting

The Periodic Safety Update Report (now formally Periodic Benefit-Risk Evaluation Report, PBRER, under ICH E2C(R2)) covers a defined data lock point period and includes:

• Worldwide marketing approval status.
• Actions taken in the reporting interval for safety reasons.
• Changes to reference safety information.
• Estimated exposure and use patterns.
• Data in summary tabulations (signals, ICSRs by SOC, etc.).
• Summaries of significant findings from clinical trials, non-clinical data, literature, and other sources.
• Signal and risk evaluation.
• Benefit evaluation, integrated benefit-risk analysis.
• Conclusions and actions.

The data tabulations come from controlled safety data; the prose comes from the medical writer or safety physician. Assisted drafting should link every statement and table to its data lock point, source extract, calculation or approved analysis.

A scoped Sia RegAI workflow can structure source extracts and prepare section drafts for review. The medical writer checks the narrative; the safety function owns signal and benefit-risk analysis; the accountable qualified person approves the final report.

Signal management

GVP Module IX (signal management) defines the lifecycle: signal detection → validation → confirmation → analysis and prioritisation → assessment → recommendation for action. Disproportionality methods (PRR, ROR, IC, EBGM) over EudraVigilance / FAERS / company database produce candidate signals; humans validate.

Where AI helps:

• Signal detection support. Run approved methods on the authorised data set and route candidates into the governed signal process.
• Literature surveillance. Continuous monitoring of MEDLINE, EMBASE, Cochrane, and conference abstracts for adverse-event signals related to in-scope products. Returns relevant articles with abstract summaries; the safety physician decides whether to investigate.
• Pre-validation triage. Pre-classifying candidate signals by likelihood of true signal vs. expected reaction, helping signal-management teams prioritise.

Critical: the regulator-facing decision (is this a confirmed signal? what action?) stays with the safety physician. AI is upstream filtering and pattern detection.

What stays human (and why)

The line we draw with PV clients:

• Causality assessment. The medical judgment of whether a drug caused an adverse event is signed by a qualified person. AI doesn't sign causality.
• Final medical review of cases. Every serious case gets reviewed by a safety physician before submission. AI accelerates the review (drafting, tabulation) but doesn't replace it.
• QPPV sign-off on aggregate reports. The benefit-risk conclusion is the QPPV's. AI drafts; QPPV decides.
• Reporting decisions on borderline cases. Whether to expedite a borderline-serious case is a regulatory and medical judgment. AI supports; humans decide.

Get those four right and the rest can be aggressive about automation.

Where Sia RegAI helps

For a scoped PV implementation, define the authoritative EMA GVP, ICH, FDA and local source set before configuring any workflow. RegReview can monitor those sources, preserve versions and route changes to the relevant safety reviewers. RegMatcher can connect approved obligations to SOPs, controls, owners and evidence, so the assessment can be refreshed without losing the earlier interpretation.

Within that governed source and review model, potential workflow uses include:

• Triage and route inbound case streams against the modular GVP definitions.
• Draft case narratives and MedDRA coding for human review.
• Generate PBRER / PSUR / PADER / DSUR sections from underlying data.
• Surface gap analysis between SOPs and current GVP module text — useful when GVP modules update or for regulator inspection prep.
• Cross-map regulatory obligations to your QMS and SOP library.

Require source links, input versions, prompts or rules, reviewer edits, approvals and export logs as acceptance criteria; verify them during validation and inspection rehearsal.

Validation and evidence checklist

Common pitfalls

• Treating AI ICSR triage as definitive. Err on inclusion. The cost of a missed case is regulatory; the cost of a false-positive is a few minutes of case-manager time.
• Letting AI draft causality. Causality is a medical judgment. AI can describe the case; it shouldn't classify causality without a qualified person co-signing.
• Generating signals without validating. Disproportionality methods produce many false positives. Always validate before reporting.
• Over-trusting MedDRA coding accuracy. Aggregate accuracy can hide material errors. Review disagreements by seriousness, expectedness, product, language and source channel.
• Forgetting reporting timelines. Day 7 / Day 15 expedited reporting and aggregate report submission deadlines are non-negotiable. Automation must be designed around the timeline, not for the timeline to be designed around automation.

Closing

The sound business case is not a generic automation percentage. Establish a baseline for volume, quality, rework, timeliness and reviewer effort; pilot one bounded use case; compare like for like; and expand only when safety and compliance acceptance criteria remain satisfied.
