Isolators, filling lines and lyophilisers proven under grade A/B before PPQ
Commissioning, qualification and validation software for sterile fill-finish where isolators, filling lines, lyophilisers and grade A/B cleanrooms all have to prove sterility assurance before the first PPQ batch.
A sterile fill-finish suite is one of the highest-scrutiny builds in pharma: restricted access barrier systems or isolators, filling lines, cappers, lyophilisers and the grade A/B/C/D cleanroom envelope around them all have to be commissioned, qualified and shown to hold environmental classification before a single vial can be filled for process performance qualification (PPQ). Deskely holds every piece of equipment, room and utility tie-in in one register with IQ, OQ, PQ and EU GMP Annex 1 contamination control evidence built in.

The problem
An isolator line, a lyophiliser and a grade B suite, and a spreadsheet cannot show which one is actually holding classification today.
A sterile fill-finish suite is not one system: it is a filling line, capping station and lyophiliser each with their own vendor FAT and SAT, an isolator or RABS with its own decontamination cycle validation, and a grade A/B/C/D cleanroom envelope with HVAC, differential pressure cascades and particle counters layered underneath.
When isolator qualification protocols, filling line OQ scripts and environmental monitoring trend data sit in separate vendor and QA folders, nobody can answer the question a pre-PPQ readiness review always asks: which room, which utility tie-in and which piece of equipment is still open.
Deskely tags every isolator, filling line component, lyophiliser and room individually, so the site can see exactly what is blocking PPQ instead of being told the suite is 'substantially validated'.
Setting up the register
Isolators, filling lines and rooms are tagged assets traced back to the user requirements specification.
P&IDs, room data sheets and equipment lists are parsed into a reviewed register, so every isolator, filling line component and cleanroom carries its URS reference, its design qualification (DQ) trace and its vendor FAT data from day one.
IQ, OQ and PQ protocols are defined once per equipment type in line with GAMP 5 risk categorisation and instantiated across every isolator, capper and lyophiliser on the line, so a new unit inherits the approved test set rather than a blank document.
Grade A/B/C/D room classification, differential pressure cascades and HVAC qualification sit in the same register as the process equipment, so environmental readiness is derived from the same evidence set as equipment-level qualification.
Execution
IQ, OQ, PQ and aseptic process simulation are gated equipment by equipment, not suite-wide.
Installation qualification confirms every isolator, filling line and lyophiliser is built to the approved design; operational qualification proves each system performs across its operating range, including decontamination cycle validation and stopper-seating force.
Performance qualification and aseptic process simulation (media fill) prove the line under simulated production conditions, with environmental monitoring data, personnel gowning qualification and interventions logged against the specific run.
Deviations from a vendor FAT, a media fill excursion or an out-of-trend particle count are logged at the specific asset or room, so PPQ readiness is not blocked by an unrelated open item in an unrelated grade D support room.
PPQ and release to GMP manufacturing
PPQ is declared from signed IQ/OQ/PQ and ALCOA+ evidence, not from a QA summary memo written the week the batches are filled.
PPQ batch release draws on the same qualification and environmental monitoring register used throughout CQV, so the evidence package a quality unit and a regulator will request is an export rather than a scramble through vendor binders.
The validation master plan traceability matrix, from URS through DQ, IQ, OQ and PQ, is maintained continuously against the register, so a 21 CFR Part 11 audit trail exists for every signed record rather than a reconstructed timeline.
Every signature carries a name, role, timestamp and reason for change, which is what a quality unit, an FDA or MHRA inspector and the site's own internal audit programme expect before a sterile line is released to routine manufacturing.
Media fill failure investigation
A single contaminated media fill unit stops the PPQ programme, and the investigation has to reconstruct exactly what that unit was exposed to.
An aseptic process simulation is only useful if a positive unit can be traced back to a cause: an intervention, a specific operator, a gowning qualification lapse, an environmental monitoring excursion in a specific grade A zone, or a fill line component that had drifted out of qualification.
That reconstruction usually means pulling the media fill run sheet, the intervention log, the environmental monitoring plate reads for that session and the gowning qualification record for every operator present, from four separate systems, while the PPQ campaign clock keeps running.
Deskely keeps the media fill run, its interventions, its environmental monitoring results and the gowning qualification status of every operator present in the same register as the isolator and filling line records, so a positive unit investigation starts from one filtered view instead of a week of cross-referencing before a root cause can even be proposed.
The aseptic dossier
Every record a grade A/B line has to produce before the first PPQ vial is filled.
Sterile fill-finish is judged on sterility assurance, not throughput. The dossier ties isolator, filling line, lyophiliser and room qualification to the media fills and environmental data that stand behind an aseptic process claim, so an inspector can trace any vial back to a signed record.
Isolator/RABS IQ, OQ, PQ protocols and reports

How it runs
From FAT to PPQ batch release.
Sterile fill-finish programmes reward a register that ties every isolator, room and utility back to the URS before FAT, because a single unqualified interface is what an Annex 1 inspection is designed to find.
