PSUR vs PBRER
The periodic safety report — and the benefit-risk evolution of it.
What a comparison is not
A comparison is SPEQ’s reading of how two published documents differ. Neither is the right answer, it is not a determination of which applies to you, and neither is summarised in a way that replaces reading it.
The Periodic Safety Update Report (PSUR) is the periodic post-marketing safety report a marketing-authorisation holder submits to regulators. ICH E2C(R2) introduced the Periodic Benefit-Risk Evaluation Report (PBRER) as the modern format — broadening the focus from safety alone to an integrated benefit-risk evaluation. In the EU, "PSUR" is now used for a report following the PBRER format.
| ASPECT | PSUR | PBRER |
|---|---|---|
| Focus | Historically safety-centric | Integrated benefit-risk evaluation |
| Standard | The periodic-report concept (older E2C) | ICH E2C(R2) format |
| Content emphasis | Safety data and signals | Benefit and risk together, with an integrated conclusion |
| EU usage | "PSUR" retained as the name | PSUR now follows the PBRER format |
| Purpose | Periodic safety re-evaluation | Periodic benefit-risk re-evaluation |
You will hear "PSUR" as the regulatory name for the periodic post-marketing report, especially in the EU — but understand that its required content now follows the modern benefit-risk format.
The PBRER (ICH E2C(R2)) is the content format: an integrated benefit-risk evaluation, not a safety-only summary. Author periodic reports to this structure regardless of whether the local name is PSUR or PBRER.
PBRER is essentially the modern evolution of the PSUR. ICH E2C(R2) reframed the periodic report from a safety-only document to an integrated benefit-risk evaluation, and regions adopted the PBRER format — the EU keeping the name "PSUR" for a report that now follows PBRER content. Treat them as the same instrument at different points in its evolution: write to the benefit-risk (PBRER) structure.
PSUR vs PBRER: frequently asked questions
Common questions on how PSUR and PBRER differ and when each applies.
What is the difference between a PSUR and a PBRER?
The PSUR is the periodic post-marketing safety report; the PBRER (ICH E2C(R2)) is its modern format, which broadens the focus from safety alone to an integrated benefit-risk evaluation. In the EU, "PSUR" is retained as the name for a report that now follows the PBRER format.
Are PSUR and PBRER the same thing?
Effectively yes, at different points in evolution. The PBRER is the updated content structure (benefit-risk, not safety-only). Regions adopted it under their existing names — the EU still says "PSUR" but requires PBRER-format content — so they are the same instrument modernised.
How often are periodic reports submitted?
On a schedule set by the regulator, typically tied to the product’s authorisation and risk (e.g., following an EU reference date list). The frequency reflects how long the product has been marketed and its risk profile, with newer products reported more frequently.
