The revised Annex 1 expects a documented contamination control strategy, qualified personnel and gowning, environmental and utility monitoring against alert and action limits, aseptic process simulation, sterilisation and filtration under control, and inspection and integrity checks of the finished containers. Most sites already do this work. The difficulty is proving how each record relates to each batch.
All the sterile evidence, linked to the batch
In Swat iQua Suite the sterile modules feed the same batch record and release file. Gowning qualifications and cleanroom status come from environmental monitoring; media fill validity comes from aseptic process simulation; sterilisation cycles, filter integrity tests, lyophilisation cycles, container closure integrity tests and visual inspection runs are linked to the batch or finished lot. A failure in any of them raises a deviation and a release blocker, so the batch cannot be released by mistake.
Media fill and line qualification
Media fill protocols — fill volume, incubation, acceptance criteria and validity period — are prepared, reviewed and approved by three different people. Runs capture units filled, incubated and positive, and any positive unit means the run fails. A passing run approved by QA sets the line’s valid-until date, and a line with no current passing media fill cannot be used for aseptic filling.
Sterilisation and filter integrity
Sterilisation cycles — moist heat, dry heat, depyrogenation, gas, radiation and filtration — are recorded with equipment, load number and parameters, plus biological and chemical indicator results. QA release is e-signed and the operator cannot release their own cycle; a cycle with a failed BI or CI cannot be released at all. Filter integrity tests — bubble point, diffusive flow or water intrusion, before and after use — are verified with segregation of duties and an e-signature.
Utilities and environmental monitoring
Utility systems such as WFI, clean steam, compressed air and HVAC have versioned alert and action limits; each result freezes the limit in force, and an action breach raises a deviation. Environmental monitoring works the same way for cleanroom monitoring points, where an action result opens an excursion that is dispositioned with an e-signature.
Swat iQua Suite covers the Annex 1 controls described here. Your contamination control strategy, qualification and validation decisions remain your own — the system makes them enforceable and traceable.
