Process validation guidelines As per ICH

 Basic

This guidance aligns process validation activities with a product lifecycle concept and with
existing FDA guidance, including the FDA/International Conference on Harmonisation (ICH)
guidances for industry,

Q8(R2) Pharmaceutical Development,

Q9 Quality Risk Management, and
Q10 Pharmaceutical Quality System.2 Although this guidance does not repeat the concepts and
principles explained in those guidances, FDA encourages the use of modern pharmaceutical
development concepts, quality risk management, and quality systems at all stages of the
manufacturing process lifecycle

 

Approach to Process Validation

Stage 1 – Process Design: The commercial manufacturing process is defined during this
stage based on knowledge gained through development and scale-up activities.
• Stage 2 – Process Qualification: During this stage, the process design is evaluated to
determine if the process is capable of reproducible commercial manufacturing.
• Stage 3 – Continued Process Verification: Ongoing assurance is gained during routine
production that the process remains in a state of control.
