A singlicate immunogenicity method to detect anti-polyethylene glycol antibodies: pre- and post-dose of PEGylated therapies.
Aim: Preexisting anti-polyethylene glycol (PEG) antibodies (APAs) may affect the efficacy and safety of PEGylated compounds. Omontys® and Krystexxa® withdrawal and SARS-CoV-2 RNA vaccine anaphylaxis have all been linked to APAs. This project aimed to develop and validate a method to detect total antibodies against PEG, pre- and post-dose. Materials & methods: The repetitive, linear PEG structure prevented the use of a bridging homogenous format, hence the requirement to use a solid-phase extraction and acid dissociation assay coupled with the Meso Scale Discovery® platform. Results & conclusion: Using singlicate analysis, the method was validated to successfully detect APA pre- and post-dose, with a crucial aspect of the method being the preparation of an appropriate negative control.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
