This presentation will concentrate on strategies used to evaluate extractables and leachable (E&L) risk and consider origins, definitions, testing and leachable risks evaluations.


To aid manufacturing and delivering new drugs to patients, disposable systems have seen significant increase in use and new technologies becoming available. Early adopters and users of single use technologies (SUT) are biopharmaceuticals and cell therapeutics; however it has been reported that E&L concerns are a significant barrier to SUT adoption.

The United States Pharmacopeia (USP) has published draft chapters (<665> and <1665>) on this subject, the latest draft having been released 1st Mar 2019 (PF 45 (2)). In addition the Parenteral Drug Association (PDA), Bio Process Systems Alliance (BPSA) and Biophorum Operations Group (BPOG) have both published recommendations for assessing E&L.

This presentation will centre around strategies used to evaluate E&L risk and consider:
  • Origins
  • Definitions
  • Testing
  • Leachable risks evaluations.
The presentation is the first in a series of webinars covering Single Use Technology. Future topics include: Physical and Functional Testing; plus Packaging, Distribution and Transit Testing.
