Identifying process variability using data science based process characterization

Process validation is an essential step in the commercialization of a new (biological-) drug. For drug product commercialization, manufacturers must validate the drug’s manufacturing process. This ensures, that the manufacuring process delivers consistently a quality product and that the patient is not at risk.

Recently, US and European regulators have issued new process validation guidelines. The new guidelines now emphasize:

  • the demonstration of process understanding;
  • risk-based identification of critical process parameters;
  • implementation of well-validated control strategies.

As a result of the new guidelines, it is now state of the art that drug manufacturers thoroughly investigate and “characterize” the manufacturing processes (stage 1 process validation) and thoroughly monitor the manufacturing process to demonstrate a state of control (Continued Process Verification, Stage 3 of the process validation).
To put the new guidelines into industrial practice, data management and (statistical-) data analytics now play a key role.
This talk explores data management and data analytics workflows for process characterization and continued process verification, in particular:

  • Data management and data analytics workflows as prerequisite for process validation
  • Statistical data analytics for process validation
  • Scale down model qualification
  • Experimental design
  • Calculation of normal operating ranges/ proven acceptable ranges
  • Monitoring/ Continuous process verification
  • Concept study how to leverage data from process characterization to develop a continuous process verification plan.
