An Overview of Recent USP Bacterial Endotoxins Standards Development

Detection of bacterial endotoxins is a critical quality attribute of parenteral pharmaceuticals and medical devices.  Bacterial endotoxins are cell wall components of Gram-negative bacteria, ubiquitous in nature, difficult to destroy and can cause pyrogenic responses or worse.

We are at a generational change in bacterial endotoxins test method options.  Creating the infrastructure to enable broader use of recombinant reagents advances the science while maintaining the safety and quality of medicines.  Recombinant reagents are derived from established biotechnology principles which begin with the same mechanism of action as the natural protein derived from horseshoe crabs; the detection of bacterial endotoxins by the Factor C protein.  Recombinant reagents also afford improvements in quality, supply chain, and sustainability.

The USP Microbiology Endotoxin and Pyrogens Subcommittee developed a recombinant reagent bacterial endotoxins test chapter which is based on the underlying science, and data from the peer-reviewed literature, sponsor and supplier validations, and ring study trials.

The presentation will provide a general overview of the Subcommittee work, and detailed information regarding the recombinant bacterial endotoxins chapter, associated guidance, and the public health reference standard endotoxin.
