Case study description Implementation of a Single Use System in a traditional department for non cytotoxic drugs manufacturing (traditional technologies used) Reasons of the decision Project development: Choice of the system System set up System validation
Current traditional system 400L stainless steel preparation tank Single sterilizing filtration (terminal sterilization product): 100L stainless steel holding tank 4 vent filter 4 sterile filter (0.2 m) + 1 filter of reduction bioburden (0.45 m) Silicone Pt-cured connection tubings
Current traditional system Filling in Class C under LAF Class C compounding room Class A/B filtration surround C AUTOCLAVE (Sterilization of the filled ampoules) 7
Single Use System: Pro&Cons Advantages: Aseptic connections reduction Increase of the sterility assurance and decreased contamination risks Decrease of cleaning/cleaning validation activities Reduction of equipments costs and related activities (i.e. equipments sterilization costs) Decreased post-filling activities done by production operators
Single Use System: Pro&Cons Disadvantages/Risks: Possibility to introduce the Single Use System on the existing production line Single Use System costs (purchase and discharge) Increase of validation activities: Preliminary evaluation of the possibility to use the Single Use System with the defined product/s Validation related costs Regulatory risks/activities: Possible regulatory requests on Single Use System Regulatory variations necessary in case of registered products (related activities and costs) Impact on project timelines, costs and risks
Single Use System: conclusions Single Use System is easy introduced only in a phase/step of production process Possibility to use two alternative systems (traditional and single use) Introduction of the Single Use System easy for a product under development/new registration How to proceed with the Single Use Project??
Project development SUS SUS drawing SUS components: Silicone Pt-cured tubings T and Y propylene connectors Polycarbonate rapid connectors Defined system: Single Use System specific validation package
Validation aspects Separate validation of the filter and of the Single Use System Filter validation according to regulatory requests: Viability Challenge Extractables Integrity test values Adsorption Single Use System validation: start of combined work Italfarmaco-Supplier

Business Drivers
Qualification
Implementation
Validating an SUS Process validation remains the responsibility of the pharmaceutical manufacturer Leveraging supplier data requires an understanding of how it was developed Materials of construction Testing procedures (e.g. pyrogens, heavy metals, solvents, E/L) System design may require features to facilitate validation Alternate receiving vessels to accommodate testing Integrity testing Desirable, but not necessarily realistic or achievable Campaigning Surge vessels, columns
Validating an SUS Conclusions Suppliers are an integral part of the quality system Unprecedented levels of transparency and data sharing and management are required Those who fully embrace true partnerships will be the most successful
Validating an SUS Materials management - no pain, limited gain Low impact mtls are relatively easy to alternate source Decreases exposure at a single supplier Gain experience of alternative suppliers quality system Financial benefits a consideration High impact materials require more work to qualify Addresses higher risks (supply interruptions, recalls) Lower frequency of use The back-up may fail before the primary Maintain high levels of support and service from suppliers
