• Facility footprint
• Acquisition of individual production systems:
– Investment
– Need for installation, commissioning,
qualification of each
– Available equipment scales vs. (GMP!) process
needs?
PROCESS INFRASTRUCTURE
• Batch operation: system idle time, transfer of
intermediates between unit steps (➜ process hold,
operator intervention, increased total process
duration…)
• Several UF / DF operations ➜ volume of TFF
buffers, process waste
• Cumulative loss of material over DSP = decrease in
yield
PROCESS OPERATION
PROCESS SUPPLY
• Long bill of materials: complex supply chain
management, vendor qualification & control,
QC requirements
• Many suppliers = many failure points
PROCESS DEVELOPMENT
• Development of custom or generic (“template”)
mRNA process
• Process optimization, characterization, qualification -
including mixing of process solutions, storage of
prepared solutions and intermediates,
chromatography resin lifetime studies…
• Process scale-up from R&D to mass scale

R&D
• Optimized, generic process
• Ready-to-use reaction mixes
• No scale-up (scale-out / scale-in-time)
• One fully automated, integrated system
• Easy installation
• Limited facility impact (small Grade D / ISO 8 room)
• Lower COGS
