Investing in New Manufacturing Technologies is
Benefiting Production, Compliance and Our Ability to
Deliver and Supply Products More Efficiently
• Enable speed to market (R&D and Operations)
• Similar Scale and Platform Throughout Develop Cycle
• Reduce capital investment
• Smaller Facility, Reconfigurable and Modular Design requires
less capital investment and match of capacity to current need

Improvements in Operating Performance
Key Technical Advances
Operational Benefits
 Up to 15 fold greater protein output
per unit volume
 Enables smaller bioreactors for same
output (2,000 Liters vs. 20,000 Liters)
 Portable equipment and disposable
technology
 Eliminates infrastructure for cleaning
and sterilization and ~45 miles of pipes
 Standardized, modular, flexible
design
 Simplifies changeovers between
molecules (from one week to one day)
 Continuous downstream protein
processing steps
 Fewer intermediate steps, less
equipment, and faster cycle times
 Real-time quality control

Amgen Singapore Facility Differs from
Conventional Design in Specific Ways
• Central manufacturing suite
•
•
•
•
Cell culture through viral filtration
Closed cell culture (aseptic connections)
Closed harvest system
Reduced personnel and maintenance activities
• Area classification
• Closed Processing Systems allow for most operations to occur
in an ISO 9 central manufacturing suite
• In-line testing and rapid microbial methods allow for
enhanced process control and detection and response
to potential quality issues
The Closed Processing Controls Negate the Need for
Conventional Physically Segregation of Cell Culture,
Harvest, and Purification

Facility Design and Operation Mitigates
Risk of Product Contamination
• Closed operations
• Aseptic connectors or aseptic tube weld
• Gamma-irradiated components and tubing
• No process transfer piping
• Concurrent cell culture, campaign harvest and
purification
• Faster production cycles, reduced hold times
• Single-use equipment
• No process transfer piping
• No stainless steel hold tanks or reactors in central suite
• 95% reduction in surface area requiring cleaning

Preparation Area
• Engineering controls to eliminate cross-contamination
• Solution mixing vessels in segregated alcoves
• HEPA filtered downflow above vessels
• Antistatic single use plastic powder transfer sleeves and
connections to mixing vessels
• Mixing vessels are single use
• Gamma-irradiated single use vessels and tubing
However, Single Use Systems (SUS)
have created a complex supply chain
• A science- and risk-based approach is used to
characterize raw materials
• It is critical to understand the underlying science with
each technology in the supply chain to reduce the risk
• The science drives raw material specifications and
change controls for suppliers
• Understanding the process and raw material inputs
can control the risk of unexpected performance
• Working transparently with suppliers is key to risk
mitigation
15
What are we doing to understand the risk
profile for single use plastic technologies?
Elements of the Risk profile includes:
• Supply Chain
•
•
•
•
On-site technical due diligence visit to supply chain
Build relationships with key technical personnel at supplier
On-going Technical group exchanges
Industry competitive intelligence
• Raw Material Characterization and Biological Impact
•
•
•
Review of supplier validation technical package
Characterization studies to link variability for form, fit and function
Extractables and Leachables with model solvents
• Raw Material Qualification
•
•
Correlate raw material variability to process parameters
Finalize raw material specifications based on process variability
• Continuous monitoring / verification of performance
•
•
Correlate supplier process variability to film performance
Establish quality control testing to insure consistent performance

2. Material characterization and biological impact
3. Continuous monitoring / verification of performance

What are we doing to understand the risk for
integrity of the bioreactor bags?.....
•
Key levers for impact :
•
•
•
•
Variability in film
Variability in the welding process
Strength of weld
Bag design
• What is the variability of each stage (lot-to-lot)?
• What incoming, in line and release testing is
used?
• Benchmark bag handling techniques
• Can we predict “good” and “ bad” bags?

Films and leachables can impact
processes in various ways
• Impact on other process steps
• Small concentrations of preservatives can interact with silicone
tubing, depressing filter bubble points
• USP Class VI testing is NOT representative of cell culture
requirements
• Consider impact of films on media and SUS performance
• Impact on cholesterol dependent cells
• Impact of multiple passages
• Users have reported sensitivity of certain cell lines to certain films
• We have made similar observations for bags used for
media holds

Advances in Analytical Technology Are Providing
Opportunities for PAT Improvement Across the
Manufacturing Process
• Process Analytical Technologies are “a system for
designing, analyzing, and controlling manufacturing
through timely measurements…with the goal of
ensuring final product quality.”

Implications of PAT Strategy for
Manufacturing
• Integration of operational quality control with
manufacturing
• Facility design should allow for at-line testing
• Production testing personnel should integrate into
manufacturing organization
• Scaling data-based decision making capabilities
• PAT will increase relevant, actionable data acquired
• Facility staff needs
• Increasing real time quality assurance on the floor
• Flexibility to accommodate both current and future
molecules
