From AAPS 2009: How To Improve Roller Compaction Processes

At the 2009 American Association of Pharmaceutical Scientists (AAPS) Annual Meeting in Los Angeles, Gerald Burke presented a case study on how Patheon Pharmaceuticals improved roller compaction processes.  Specifically, the case study focused on the influence of roller compactor settings on Critical Quality Attributes (CQAs) and the early prediction and control of granule porosity.

Why Use Process Analytical Technology (PAT)/Quality by Design (QbD) for Bioprocess Monitoring?

PAT and QbD in Bioprocess Monitoring

Use of PAT/QbD in BioProcess Monitoring

During a recent online seminar, Brian O’Sullivan discussed why Process Analytical Technology (PAT) and Quality by Design (QbD) are used for Bioprocess Monitoring.  Brian’s presentation included the following points:

  • When you think of biological processes, they are complex manufacturing processes with high process variability
  • Development of robust and reliable bioprocesses can be difficult
  • Increased risk of contamination due to sampling for offline measurement
  • Process losses can be high
  • Process Analytical Technology (PAT) provides a means of improved process understanding, optimization, and control
  • Return on Investment in Process Analytical Technology (PAT) comes from both R&D and manufacturing.  Typically, this is achieved by getting more robust processes to market quicker which ultimately minimizes the process risks from batch to batch and also improves process optimization
  • Process Analytical Technology (PAT) is critical in the transfer of knowledge from lab to manufacturing
  • Reduced sampling time and online method minimize contamination risks
  • Quality by Design (QbD) approach identifies and minimizes manufacturing risk through identification of Critical Quality Attributes (CQAs), what causes variability in CQAs, and control of CQAs
