Topic 1 – Stage 2 Process Validation: Determining and Justifying the Number of Process Performance
Qualification Batches
This discussion paper proposes ideas for answering the question “How many process performance
qualification batches (PV stage 2) are needed to demonstrate a high degree of assurance in the manufacturing
process and that the control strategy is sufficiently robust to support commercial release of the product?”
The purpose of this paper is to stimulate further discussion and suggest potential practical application.
Topic 2 – Stage 3 Process Validation: Applying Continued Process Verification Expectations to New and
Existing Products
This discussion paper proposes ideas for answering the questions “How is Stage 3 monitoring and testing
following PPQ determined, as part of the lifecycle approach to PV?” “What is the impact of the lifecycle
approach to monitoring and testing of existing/legacy products?” The purpose of this paper is to stimulate
further discussion and suggest potential practical application.
