This short course will aim to outline the considerations and direction taken when evaluating and understanding Extractables and Leachables present in either Single-Use Systems or Final Packaging. The course will be begin with outlining key fundamentals of material chemistry and typical leachable sources, while also highlighting properties that govern migration of these compounds. Further incorporation of industry-recognized "best practices" with these concepts will introduce evaluation strategies and explain the thought process in designing appropriate analytical studies to assess these systems. Throughout the course, strategies to overcome typical obstacles encountered in such E&L programs will be illustrated. Finally, resources associated with establishing suitable testing criteria and safety assessments will be presented.

The topics to be covered:

  • Which phenomena are described by the term “protein aggregation”?
  • How do protein aggregates form, and what factors influence their formation?
  • What are the consequences of aggregate formation?
  • Can aggregation be predicted?
  • What are the key analytical challenges and tools for characterization of protein aggregates?
