Impact of Regulation and Critical Process Parameter (CPP) on Bacterial Retention Testing (BRT) Design


In Part 1 of this webinar series, we will discuss the implications of current regulatory trends and how this impacts the expectations for bacterial retention testing (BRT) studies. We will also address the challenges of applying critical process parameters (CPP) to the design of a bacterial retention study, as a part of the aseptic filtration validation process. The recent regulatory observations will be discussed as cases.

In this webinar, you will learn:

  • How BRT fits into the validation strategy for aseptic filters
  • About current regulatory trends and expectations for BRT
  • How to best incorporate CPP for various drug delivery systems

The 2nd webinar in this series, Case Studies: How to Incorporate Critical Process Parameter (CPP), is also available.
