An aseptic process simulation shows that a filling process can produce sterile product, by running it with growth medium instead of product and incubating the filled units. EU GMP Annex 1 and other GMP guidance expect APS to represent the routine process, to be repeated periodically, and to be treated as a failure when contaminated units are found. Swat iQua Suite covers the Annex 1 controls for aseptic process simulation by connecting the media-fill record to what happens on the line.
Protocol and run
The media-fill protocol defines fill volume, incubation, acceptance criteria and how long a passing result keeps the line qualified. It is versioned and approved with three-way segregation of duties and an e-signature. Each run is planned against an approved protocol and a filling line, moves through in progress and completed, and records the numbers of units filled, incubated and positive. QA then approves or rejects the run with a segregated e-signature.
The gate on the shop floor
A passing run sets the line’s valid-until date. When an operator starts a sterile step in the electronic batch record and the aseptic line is captured on the step, the sterile step gate checks for a current passing media fill on that line — alongside the operator’s gowning qualification, cleanroom readiness and open environmental-monitoring excursions. If the media fill has lapsed or failed, the step does not start.
- A failed run triggers the sterile-impact process and a deviation.
- Media-fill status is part of the sterile release checklist in Batch Release.
- Cleanroom readiness and EM excursions come from Environmental Monitoring.
