PROTOCOLREFERENCE OUTLINE

Aseptic Process Simulation (APS) Protocol

Full APS/media fill protocol template for liquid fill-finish operations. Covers pre-simulation activities, execution, acceptance criteria, and post-simulation reporting per Annex 1 §8.

What a template is not

A template is a document baseline to adapt inside your own quality system. SPEQ does not approve, validate, or take responsibility for what you issue from it, and using one is not evidence of compliance.

PURPOSE

A media-fill protocol for liquid fill-finish that defines, before execution, how the aseptic process will be simulated, which interventions will challenge it, how many units will be run and read, and what result will be accepted. A simulation designed after the fact to match a comfortable outcome proves nothing; the protocol exists to fix the design, the interventions, and the acceptance criteria in advance.

What's Inside

✓Simulation design and the worst-case rationale — why this configuration represents the real process at its least favourable
✓Run size, container format, and unit count, with the justification for the number chosen
✓Intervention list separating routine from non-routine, each with the frequency it represents in production
✓Incubation parameters — temperature stages, duration, and reading points
✓Acceptance criteria stated before execution, including the action on any positive unit
✓Execution record with a contemporaneous intervention log, naming the operator for each intervention
✓Incubation and reading records, results, investigation triggers, and the reporting route into the contamination control strategy

How to Use It

1Design the simulation against the real process at its worst case — longest run, most interventions, least favourable shift pattern
2List every intervention and justify its inclusion or exclusion; an unlisted intervention performed during the fill invalidates the design
3Fix run size, incubation, and acceptance criteria in the approved protocol before any unit is filled
4Execute with a contemporaneous log — an intervention reconstructed after incubation is not a record
5Read at the defined points by trained personnel, and preserve any positive unit for identification
6Report the outcome into the contamination control strategy, and investigate any positive against it rather than in isolation

REGULATORY CONTEXT

EU GMP Annex 1 (2022) sets expectations for aseptic process simulation including worst-case design, intervention coverage, run size, incubation, and the treatment of contaminated units, and requires the outcome to feed the contamination control strategy. FDA's aseptic processing guidance frames comparable expectations for US-marketed product. PDA Technical Report 22 informs the practical design embedded here and is industry guidance rather than regulation. The worst case at your line, and the acceptance you apply, remain your determination.
