Questions to Consider
• How is tech transfer performed within a CDMO?
• Multi-product facilities
• Phase I to Phase III projects
• Are there standard approaches that ensure 100% success?
10. Confidential
11
• Key goal is to ensure seamless transfer of process parameters, raw materials
and process knowledge for cGMP manufacturing
• Initiate process transfer while process development is on-going; 4-5 months
prior to manufacturing start
• Need to reduce gaps in equipment and raw material grades between
development and manufacturing
• Use of platform upstream and downstream processes minimizes changes in
manufacturing operations
• Templated documents for process transfer and manufacturing ops

• Tech transfer milestones defined with T=0 as
cell culture vial thaw or harvest
• Process descriptions, batch record review and
floor support are key deliverables from
process development

• Inoculum train duration and parameters (temperature, agitation
and CO2 %) are fixed for all SKI cell lines
• Several production bioreactor parameters (for e.g. temperature
set point, DO set point, seed density) are consistent among SKI
processes
• Nutrient medium and feed media are fixed for all SKI cell lines
• Product-specific nutrient supplements or process parameters
can be included
• Process duration is generally 14 days – range of 12-16 days
depending on desired QTPP

• Difficult to develop a standard platform processes for manufacturing non
antibody products
• Changes to basal medium, feeds, chromatography resins, buffers can be
frequently necessitated to achieve desired productivity and product quality
• Final process tested in same scale bioreactors prior to start of cGMP
manufacturing
• Developed and manufactured a series of gp120 vaccine proteins in CHO cell
lines where first molecule required changes to manufacturing operations, but
subsequent molecules were transferred as a ‘platform’ process

Examples for non-standard process

• No seed bioreactor operations: no

inoculation using shake flasks
• Vendor liquid for all raw materials
• No use of single-use BPC bags
• Deed and supplement addition based
on cell growth,
• Harvest day dependent on cell growth
and viability

• Commercial process development and commercial launch manufacturing is
often being expedited
• Limited changes from FIH to commercial processes to reduce time required for
BLA filing
• Follow same approach as FIH process transfer, but provide NOR
definition and FMEA RA to enable CPP and critical raw materials
assessment
• Important to develop qualified scale-down models to support PPQ readiness,
commercial manufacturing and CPV
• PPQ campaign performed using initial risk and criticality assignments; PAR

• Platform-based process development is an important starting point to
streamline process transfer and manufacturing operations
• Need to ensure process scalability at pilot-scale prior to GMP manufacturing
• Equipment and raw materials must be aligned between process development
and manufacturing
• Minimize changes to standard practices, equipment platforms and document
templates
Does each new process require a ‘full’ tech transfer?
Focus only on non-platform, non-standard process changes
