Key points
What ICH E2C(R2) changed when the PBRER superseded the PSUR
| PSUR (older format) | PBRER (ICH E2C(R2)) | |
|---|---|---|
| Core orientation | Primarily a periodic safety data summary | Explicitly a periodic BENEFIT-RISK evaluation — safety data in service of that judgment, not just reported alongside it |
| Benefit information | Often limited or addressed separately from the safety summary | Benefit information is integrated directly, specifically to support the benefit-risk analysis section |
| Reference safety information | Often used the local label directly | Explicitly built around the Reference Safety Information (RSI derived from the CCSI) as the expectedness baseline |
| Cumulative view | Present, but interval-focused reporting was more common in practice | Stronger emphasis on cumulative, not just interval, review — the interval sits inside the full product history |
| Global harmonisation | Format varied more by region | Designed as a single global format multiple regulators can accept, reducing duplicate report preparation |

ICH E2C(R2) didn’t simply rename the periodic aggregate report — it restructured what the report is fundamentally for. The older PSUR (Periodic Safety Update Report) format centred on summarising safety data accumulated over a reporting interval: case counts, signal status, actions taken. Benefit information, where it appeared at all, often sat somewhat separately from that safety summary, and cumulative review, while present, wasn’t always the format’s structural centrepiece in practice.
The PBRER (Periodic Benefit-Risk Evaluation Report) reorients around a single, explicit deliverable: an integrated benefit-risk judgment. Benefit information isn’t an addendum — it’s built into the structure specifically to support the benefit-risk analysis section this module gives its own dedicated lesson to. The report is also explicitly anchored to the Reference Safety Information, derived from the same Company Core Safety Information that Module 6 established as the expectedness baseline — meaning the PBRER isn’t just reporting new cases, it’s continuously re-evaluating them against a defined, traceable reference point.
A second major shift is genuinely structural: the PBRER was deliberately designed as a globally harmonised format that multiple regulators can accept with minimal region-specific rework, in contrast to a PSUR landscape where format expectations varied more by region and companies often maintained parallel, overlapping report preparation processes for different markets. That harmonisation is a direct efficiency gain — Lesson 8.9’s coverage of regional variations shows that some region-specific differences persist even under PBRER, but meaningfully less duplicated effort remains than under the older format.
In practice, both terms still circulate — some organisations, some legacy products, and some regional guidance documents continue to reference "PSUR" even where the actual report being prepared follows PBRER structure and content requirements. Knowing the distinction precisely — and specifically knowing that the benefit-risk analysis section is the PBRER’s genuine structural innovation with no direct PSUR equivalent — is exactly the kind of detail that separates someone who knows the acronym change happened from someone who understands why it happened.
Important
The name itself is the clearest signal of what changed. "Periodic Safety Update Report" describes a safety data summary. "Periodic Benefit-Risk Evaluation Report" describes a judgment — safety data is still central, but it now exists explicitly in service of an integrated benefit-risk conclusion, not as a standalone deliverable.
