The revised Annex 1 did more than tighten sterile manufacturing rules — it made the Contamination Control Strategy the organising document of your entire quality approach. Inspectors now read it first.
The revision of EudraLex Volume 4, Annex 1 was published on 25 August 2022 and became applicable on 25 August 2023, with a single deferred point — 8.123, on lyophilisation — applying from 25 August 2024. It has been fully applicable for nearly two years, which means “we are still working on it” is no longer a defensible position.
The CCS is not a document exercise
The Contamination Control Strategy must be implemented across the facility, defining critical control points and assessing the effectiveness of every control. Three obligations are routinely underestimated:
- It must be actively reviewed and updated — not written once and filed.
- It must drive continual improvement.
- Its effectiveness must form part of periodic management review.
Encouragingly, Annex 1 does not require you to rebuild what already works: existing control systems may not need replacement, but they must be referenced in the CCS. It is an integrating document, not a demolition project.
Lyophilisation: the deferred point
Point 8.123 requires manually loaded or unloaded lyophilisers without barrier separation to be sterilised before each load. Automated or closed-barrier systems may justify a different frequency — but that justification has to be documented in the CCS.
Don’t miss Annex 19
A revision of Annex 19 (Reference and Retention Samples) was published on 24 June 2026 and becomes applicable on 24 September 2026. It has attracted little commentary, which is precisely why it is worth acting on now rather than discovering it at inspection.
Also on the horizon: a consultation on a revised Chapter 4 (Documentation), a revised Annex 11 (Computerised Systems, still governed by its 2011 version) and an entirely new Annex 22 on Artificial Intelligence closed in October 2025. No final text has been published — but the direction of travel is clear.
How findings are classified
Inspectorates classify deficiencies as Critical, Major or Other, following the PIC/S approach designed to bring consistency between inspectors. Historically, quality system failings have led published findings year after year — which is why readiness starts with your QMS, not your cleanroom.
How PQRA helps
PQRA runs gap assessments, CCS development, remediation and mock inspections — so that inspection day confirms what you already know.
