Presentation toEngineering Conference International Integrated Continuous Biomanufacturing Conference Implementing process closure and continuous processing into the modern biopharmaceutical facility Oct 23, 2013Castelldefels, Spain
Finally! The Safest Process is Closed, Where the Environment is a Parameter without Critical Aspect The Biopharmaceutical Industry is Changing We have the Technology
Environment does not represent a Critical Aspect (No Impact) • Product is not exposed to the surrounding environment • Additions and withdrawals performed in closed fashion • Validatedto show sufficient layers of protection against risk of contamination from the environment • Risk of contamination is not mitigated by housing operation in bioburden-free or particulate-free environment • Contamination of closed system = breach of integrity NOTE:Closed Sterile (although sterile is one form) ALSO:Closed Single Use Systems (although one form) Closed Process Defined
APPLYING CLOSED SYSTEM CONCEPTS:The INCREDIBLE SHRINKING Future Facility
e.g. 2 products 1980s Traditional Multiproduct Facility
Many silos Highly classified (to reduce “risk” of bioburden) 1980s Traditional Facility Redundant upstream Redundant centrifuges 2 X 3 production BRX Redundant downstream
Shared Shared Product 1 Product 1 1980s Traditional Facility Product 2 Product 2 UPSTREAM CELL (+) DOWNSTREAM CELL (-)
Not new concept Courtesy Scott Probst, Bayer, BPOG
Reminder: Tell QA people to close their eyes and plug their ears For the rest of us…
1980s Traditional Facility Shared Multiproduct Unclassified! And regulatory agencies know about this “secret”
DECLASSIFY Eureka! Bioreactors are closed! REMOVE WALL
Close the Bioreactor NOT cove corners! AIRLOCKS NOT REQUIRED Solution for Successful Cell Culture: Closed Media Containers
Sterile filter clarified broth = briefly exposed 0.2µ filter after CENTRIFUGATION to close Logistical segregation
Sterile filter clarified broth = briefly exposed Declassified; HVAC segregation no longer required Airlocks no longer required
When Environment = No Critical Aspect Physical segregation not required Product 1 is closed Product 2 is closed
If Environment = No Critical Aspect Ballroom Multipurpose Room Efficiency in Centrifugation Use Likely Efficiency in Inoc Prep Likely: Cadence of 1 BRX every 2 days
If Environment = No Critical Aspect Single redundancy likely sufficient
Sterile Filter all Buffers or Use < 24 hours If Environment = No Critical Aspect Use Protected Powder Additions and Closed Liquid Additions
If Environment = No Critical Aspect Close Systems Sanitize skids Blind runs
If Environment = No Critical Aspect Use Single Use Systems
Regulatory Concern If Environment = No Critical Aspect If closed
If concern overcome With Technology Improvements If in line dilution used If cytocentric isolator used
Consolidated V+ / V- If Environment = No Critical Aspect Smaller volumes required Note fewer staff
If Environment = No Critical Aspect If all SS: UC space above
If Environment = No Critical Aspect 9900 m2 5400 m2 + 380 m2 buffer hold UC
If Environment = No Critical Aspect 500 m2 ISO 8 4000 m2 ISO 8, 1000 m2 ISO 7 How might this look?
Batch Continuous Smaller volumes & areas required
Mabs Model: • Perfusion versus Batch Cell culture • Continuous Harvest/Clarification (ATF, centrifuge, etc • Continuous Capture (SMCC Protein A) • SMB/SMCC where possible in multi-chrom operation • Nanofiltration • UF/DF & Bulk Fill Batch Continuous
Requirements: • All operations must be closed and synchronized for long term operations • Cell Culture must be “bpsterile” • Clarification cannot contaminate upstream (but…) • Capture must be closed (but…) • Any static hold steps must be “bacteriostatic” • If continuous, UF/DF & Bulk Fill must be bacteriostatic Batch Continuous
Metrics from benchmark projects and models: • Assuming 5:1 lower titer in Perfusion versus Batch • 15K batch BRX for 1000 kg protein • 1K to 4K perfusion BRX for 1000 kg protein • Harvest batch 20K in 4-6 hours after 12-14 days • Harvest continuous 24/7 (1-3 BRX volumes/day) Batch Continuous 5000 m2 batch 3000 to 3800 m2 continuous ( -24 to -40%)
Assume no change Batch Continuous Assume 24% reduction
Batch Continuous Further 1000 m2 space savings or more achievable
Closed + Continuous = Low Cost Closing #1 Less competitive Higher cost Less flexible Closed & Continuous Facility Cost Project Risk Lower cost More competitive Highly flexible
