10. Controlled Non-Classified (CNC) DS Manufacturing
Benefits
• Lower Operating Costs
– Gowning/transitions
– Environmental Monitoring
– Energy
• Lower Construction Costs
– HVAC equipment and
ducting
– Personnel and material
airlocks
• Faster construction and
qualification
– Delay capital investment
Nov 2013
Considerations
• High degree of assurance
that process equipment is
closed
• Defining risk based and
effective design and
operating principles
• Facility organization to
manage the interface
between manufacturing and
external environments
• Managing planned and
unplanned system breaches
• Assurance of environmental
control

11. Functionally Closed Processing
• System Closure established and maintained during
processing
• Limited environmental exposure (or none) between
processing; pre-use sanitization
• Consideration for system impact on environment
during “open” status
Nov 2013
ISPE Strasbourg

12. Closed Processing: Stainless Steel Systems
• More complex design
• Vessel and transfer line can be
steamed and sanitized without
opening
• Integrity testing possible
• Precedent for CNC manufacturing
• Facility segregation may not be
necessary
May not be flexible!

• Possibility of leaks (integrity test may not be possible)

≥
Open Connection in Grade C
What could be in a CNC environment?
• Bacteria, mold, virus
• Cell culture material (from spill)
• In-Process API from another process
Sanitization measures need to be validated
Nov 2013

15. Application of CNC to Concurrent Multi-Product Design Concept
• Concurrent multi-product process: A facility where different products of the
same or different class are manufactured at the same time in parallel.
– More challenging than a ‘campaign’ scenario where production has been
sequenced to allow temporal segregation with effective cleaning and changeover.
• Application of Quality and Scientific Risk Management approaches
– Special considerations for product class, product compatibility and requirement
for product containment
• Assumptions
–
–
–
–
Shared media/buffer prep, bioreactor, harvest and purification process operations
Extensive use of single use components
Product specific validated cleaning for product contact equipment/parts
Enhanced controls for some operations (inoc. prep, column packing, final DS
filtration)
– Compatible products requiring no special handling

16. Controlled Non-Classified (CNC) plus Multi-Product
Manufacturing
Benefits
• Lower Operating Costs
– Gowning/transitions
– Environmental Monitoring
– Energy
– Capacity Utilization
• Lower Construction Costs
– HVAC equipment and ducting
– Personnel and material airlocks
• Faster construction and
qualification
– Delay capital investment
Nov 2013
Considerations
• Defining risk based and effective
design and operating principles
• The additional complexity of
procedural controls and flow-path
management without physical or
temporal segregation
• Facility organization to manage the
interface between manufacturing
and external environments
• Managing planned and unplanned
system breaches
– Risk cross contamination
• Contamination detection and lot
disposition
• Assurance of environmental control

33. In Conclusion
The leading Biopharm companies via BPOG are collaborating to define
appropriate area classification for multi-product ballroom operations
by;
• Developing common definitions and sharing best practices
– Application of Quality and Scientific Risk Management approaches
– Considerations for closed processes utilizing technical and procedural
advances
– Guidance for Industry*
• Influence the environment – A work in progress
– Internal Quality and Regulatory
– External Regulatory authorities
• FDA Meeting Highlights
• New work streams to expand the concepts
