Technology transfer could be considered as the corner stone of biodevelopment activities, as it is required each time people want to switch from a lab or a facility to another. It is expected to be handled in a methodical manner, following regulatory requirements, in order to ensure patients safety. Difficulties often come from differences between sending and receiving entities, where equipment, level of resources, internal culture, can be different. In case of failure, the cost can be huge for a drug maker.
This presentation will cover points to consider for successful tech transfers, and includes lessons learned from real cases.
In this webinar, you will learn:
● How to design a bioreactor model in order to scale up a process.
● How to build a team and tech transfer a process.
● How to accurately assess the success of a tech transfer.

Process transfer is regulatory defined
ICH Q10:
“The goal of technology transfer activities is to transfer product and
process knowledge between development and manufacturing, and
within or between manufacturing sites to achieve product
realization. This knowledge forms the basis for the manufacturing
process, control strategy, process validation approach, and ongoing
continual improvement.”
Process Transfer
Transfers have to be performed in an organized, methodical manner, with appropriate documentation
We will focus on the transfer of process parameters and process knowledge (data)

Consolidate process knowledge into transferable documentation,
Analyze gaps and risks,
Execute the Tech Transfer: work the plan,
Demonstrate technical success: Meet Acceptance criteria,
Finalize transfer: documentation, support of regulatory activities, follow-up actions, lessons learned.

Project Charter
Set expectations and responsibilities between partners
Project charter must include:
A well-defined team structure
Sub-teams for different disciplines
Connect counterparts
Establish communication paths
A well defined governance structure to address issues
Clearly described roles and responsibilities
Clearly established success criteria

11. A Process Description document with an overview of each step and key process parameters is required
Information should be described in a site and scale independent manner
Site-specific details from previous process installations should also be gathered as examples
For example:
Buffers may have been prepared in batch or via in-line dilution
Bioreactors may have been operated with different sparger configurations

Gap analysis
Gaps can be addressed by
changing equipment, procedures,
or the process.
Changes may require specific new
validation studies or may be
covered through the Process
Qualification validation.

Quality Risk Management
Risks are inherent to
technology transfers
Identifying, assessing, and
mitigating - or - accepting
risks defines the project
work scope of a transfer
From ICH Q9, two primary principles
of quality risk management are:
Evaluation of risk to quality should be based
on scientific knowledge and ultimately link to
protection of patients
The level of effort, formality, and documentation of
The quality risk management process should be
commensurate with the level of risk

Process “Q/q”ualification
It is a demonstration that the process is
performing correctly at the receiving unit.
It is important to have Pre-defined Success
Criteria: step yield, impurities, titer, etc.
15. Process Transfer Key activities
15 Managing process scaling and tech transfer
Process changes
Some process changes are inevitable based on
major differences in facility, equipment, or
operational practices.
Proper experiments must be performed to
determine acceptability of the change. Small-
scale models may be a good tool for examining
the effects of changes.
Pre-defined success criteria are key to timely
progress and make decisions. Otherwise, how
do you know if the proposed change is
acceptable?
