FDA's Endotoxin Training Overview

FDA's Endotoxin course will provide an overview of the FDA posted on their web site on Tuesday, July 12, 2011 a notice that they had withdrawn the 1987 Guideline on Validation of the Limulus Amebocyte Lysate Test as an End Product Endotoxin Test for Human Parenteral Drugs, Biological Products and Medical Devices. They advised that the 1987 Guideline is considered obsolete and does not reflect the Agency's current thinking on the topic. In lieu of this document, the FDA advised that they would be issuing a Guidance for Industry on Pyrogen and Endotoxins Testing: Questions and Answers during the November/ December 2011 timeframe. After much delay, this NEW Guidance was released in June 2012. The EP also revised their guidance document 5.1.10 Guidelines for Using the Test for Bacterial Endotoxins (Oct 2014).

The FDA referenced, however, three documents that they believe have more than offset the previous FDA Guidance that was withdrawn. They advise that these documents be referenced for the fundamental principles of the gel clot, photometric and kinetic test methods. This NEW, revised Guidance supplements the above three documents and addresses those issues that may be subject to misinterpretation, not covered in compendial procedures or in the previously available Guidance document. The EP General Chapter 5.1.10 has undergone several revisions to include

1) endotoxin limits for specific substances or product,

2) the use of 2.6.30 Monocyte Activation Test as an alternative to rabbit pyrogen,

3) limiting the Rabbit Pyrogen test, and

4) the use of Recombinant Factor C.

Low Endotoxin Recovery has recently dominated endotoxin discussions since this was observed within a monoclonal antibody formulation in 2013. The USP Microbiology Expert Committee has remained interested in this subject and in 2016 provided their opinion after extensive peer and regulatory reviews. This subject, along with the various Endotoxin Test Guidances will be presented during this interactive, live training webinar.

The objective of this live training webinar is to explore the NEW/REVISED Guidances for Industry on Pyrogen and Endotoxins Testing which addresses those issues that may be subject to misinterpretation, and are not covered in compendial procedures or in the currently available Guidance documents and how they impact testing within the typical Quality Control laboratory. Examples of FDA Warning Letters which illustrate problems associated with endotoxin will also be provided. It will also discuss the issue of LER and the conclusions reached by the USP Microbiological Expert Committee.

This live training webinar includes the following for each registered attendee:

  • A copy of the presentation slides
  • A certificate of training for attendee records
