All parenteral therapies, including every lot of injected drugs, vaccines, medical devices, must be tested for pyrogens to ensure patient safety. Bacterial endotoxins test methods were developed as a highly sensitive detection method for bacterial endotoxins, after the discovery of a clotting cascade in horseshoe crab blood. However, horseshoe crab species are limited to some inshore coastal habitats along the Atlantic coast of the USA and others throughout Asia. Fully functional horseshoe crab clotting factors can be manufactured via recombinant protein production, and several BET methods featuring recombinant horseshoe crab proteins have now been developed for commercial use. Recombinant Bacterial Endotoxins Test (rBET) methods based on the use of recombinant Factor C (rFC) were established in the European Pharmacopoeia \u2014 however, these methods have not yet been granted compendial status in the United States Pharmacopoeia (USP). In order to facilitate dialogue between stakeholders, the Physicians Committee for Responsible Medicine hosted two virtual roundtable discussions on the perceived barriers to the use of rBET methods for US FDA requirements. Stakeholders agreed that multiple rFC-based methods have been demonstrated to have suitable analytical performance, as described in ICH Q2 on the Validation of Analytical Procedures and USP &lt;1225&gt; on the Validation of Compendial Procedures. United States Pharmacopoeia compendial inclusion of the rFC-based and other rBET methods was favoured, in order to reduce the additional burdens created by a lack of global harmonisation on BET testing requirements.<\/jats:p>","DOI":"10.1177\/02611929231204782","type":"journal-article","created":{"date-parts":[[2023,10,19]],"date-time":"2023-10-19T04:24:09Z","timestamp":1697689449000},"page":"401-410","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Barriers to the Use of Recombinant Bacterial Endotoxins Test Methods in Parenteral Drug, Vaccine and Device Safety Testing"],"prefix":"10.1177","volume":"51","author":[{"given":"Elizabeth","family":"Baker","sequence":"first","affiliation":[{"name":"Physicians Committee for Responsible Medicine, Washington, DC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Ponder","sequence":"additional","affiliation":[{"name":"Physicians Committee for Responsible Medicine, Washington, DC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes","family":"Oberdorfer","sequence":"additional","affiliation":[{"name":"Rapid Micro Biosystems Europe GmbH, Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ingo","family":"Spreitzer","sequence":"additional","affiliation":[{"name":"Paul Ehrlich Institute, Langen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jay","family":"Bolden","sequence":"additional","affiliation":[{"name":"Eli Lilly, Indianapolis, IN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marine","family":"Marius","sequence":"additional","affiliation":[{"name":"Analytical Sciences, Sanofi Vaccines, Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thierry","family":"Bonnevay","sequence":"additional","affiliation":[{"name":"Analytical Sciences, Sanofi Vaccines, Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristie","family":"Sullivan","sequence":"additional","affiliation":[{"name":"Physicians Committee for Responsible Medicine, Washington, DC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,10,19]]},"reference":[{"key":"bibr1-02611929231204782","volume-title":"Expert Committee proposes chapter for endotoxin testing using non-animal derived reagents","author":"USP","year":"2023"},{"key":"bibr2-02611929231204782","first-page":"265","volume":"115","author":"Levin J","year":"1964","journal-title":"Bull Johns Hopkins Hosp"},{"key":"bibr3-02611929231204782","doi-asserted-by":"crossref","unstructured":"Smith DR, Beekey MA, Brockmann HJ, et al.
