Gowning up× Uncontrolled access to production areas
× Access to toilets × Unsanitary toilets
× Inadequate gowning and hygiene procedures× Poor gown management× Inappropriate gowning validation/limits× No exclusion criteria
× Removal of outdoor clothing× Inadequate conditions for initial gowning× poor cleanroom practices

× Facility condition- Walls- Floors- Joints
× Equipment condition- Cleanliness- Rust- Damage

Vial processing
6
× Cycle validation
× Calibration and cycle monitoring
× ISO classification and routine monitoring
× Machine function
× Configuration of critical parameters
× Maintenance - Water filters- Corrosion prone- Perspex components

Aseptic filling 1 (Line set-up) × Poor cycle control- Wet equipment
× Poor aseptic technique
× No EM during set-up
× Sterilisation of critical surfaces
![Page 9: Webinar presentation: Sterile medicines - lessons from](https://reader033.vdocuments.us/reader033/viewer/2022042614/6263d4b99a9d7e1f474f629b/html5/thumbnails/9.jpg)
Aseptic filling 2 (Ampoule filling)
× No change control× No review of HVAC× No re-classification× No media fills× Batches released× Site AP aware!
× Particle excursions
× Poor aseptic practice

Aseptic filling 3 (Non-filterable product)× Deviation investigation- Loss of tube integrity- Leak detected by camera- Batch segregated based on
times- Portion of batch released
× No knowledge of location of leak
× No knowledge of volume of drip reservoir
× Inadequate determination of breach of sterility

Media fills (APS)
Inadequate microbiological expertise
× Inadequate program design× Frequency× Ensure all operator involvement× Acceptance criteria× Investigation of failures× Invalidation of positive units
![Page 12: Webinar presentation: Sterile medicines - lessons from](https://reader033.vdocuments.us/reader033/viewer/2022042614/6263d4b99a9d7e1f474f629b/html5/thumbnails/12.jpg)
Terminal sterilisation (LVP)‘Dummy’ bags used to fill load(when partial load filled)
× Many bags not marked as ‘dummy’ bags× Not possible to guarantee removal from each load
Validated sterilisation – full cycle only
Marked bags manually removed from inspection line

Packaging and visual inspectionHandling of packed product× Product dropped >1m× Integrity test samples taken before drop
Visual Inspection× Inadequate operator training× Equipment set-up issues× Defect monitoring× AQL testing× Reconciliation (training/challenge units)
Integrity Testing× Sampling plans× Validated method× Calibrated equipment

Quality Control (microbiology)Sterility testing× Incorrect sampling plans× Lack of validation× Poor environmental controls× Inappropriate invalidation approach.
Environmental Monitoring× No risk assessment× Inadequate response to excursions× Data integrity
× ID policy× Objectionable organisms× Pre-sterilisation bioburden
Endotoxin Testing× Incorrect sampling plans× Incorrect MVD (pooling)
Integrity Testing (CCIT)× Inappropriate test conditions× Positive controls

Summary• Large variability in compliance with GMPs• Issues not restricted to certain geographic
area(s)• Manufacturer knowledge management is
critical• New Annex 1 should help clarify expectations
and drive consistency between industry and regulators
