Statistics for FDA Process Validation (3.0 days):

This course focuses on how to establish a systematic approach to implementing statistical methodologies into a process development and validation program consistent with the FDA guidance. This course teaches the application of statistics for setting specifications and assessing measurement systems (assays), using design of experiments (DOE) for process design, establishing a strategy for process qualification, and ensuring process control/capability. All concepts are taught within the three-stage product cycle framework defined by requirements in the process validation regulatory guidance documents.

Statistics for FDA Process Validation Objectives:

  • apply statistics to set specifications and validate measurement systems (assays)
  • develop appropriate sample plans based upon confidence and power
  • implement suitable statistical methods into a process validation program for each stage:

Stage 1 – Process Design
◦ utilize risk management tools to identify and prioritize potential critical process parameters
◦ define critical process parameters and operating spaces for the commercial manufacturing process using design of experiments (DOE).

Stage 2 – Process Qualification
◦ assess scale effects while incorporating large (pilot) scale data
◦ develop process performance qualification (PPQ) acceptance criteria by characterizing intra and inter-batch variability using process design data and batch homogeneity studies
◦ develop an appropriate sampling plan for PPQ.

Stage 3 – Continued Process Verification
◦ develop a control plan as part of a risk management strategy
◦ collect and analyze product and process data
◦ ensure your process is in (statistical) control and capable.
