Answer
Perfusion processes have specific aspects to be considered for process validation that are different from traditional fed batch processes such as: extended cell generations and associated genetic stability during production, consistent process operation, and product characterization consistency at all stages of the production process. Other process validation guidance should be considered and properly applied to N-1 perfusion and production perfusion processes.
