Navigating EU GMP Annex 1: The Latest Updates For Final Sterile Filtration And Single-Use Assemblies

Annex 1 no longer asks manufacturers to show that each control works in isolation. It asks them to show how the controls work together, and that changes how filtration design, integrity testing, aseptic connections, and single-use assemblies get justified. This white paper looks at where the revised guidance leaves room for judgment and where it demands evidence: the trade-offs of redundant filtration, what happens when PUPSIT is not feasible, whether filtration assemblies belong inside or outside Grade A environments, and why packaging, transport, and particulate controls now draw inspection attention. It also considers how far supplier documentation can support a contamination control strategy.

See how these expectations fit together.
