Peptide Impurities and GLP-1

Controlling peptide-related impurities is essential to meet regulatory requirements and ensure product quality. The presence of impurities in drug substances and finished products can pose significant immunogenicity risks to patients, potentially leading to drug recalls or warning letters from regulatory bodies.
In this webinar, Dr Manoj Metta from the United States Pharmacopeia (USP) will discuss challenges, regulatory expectations and USP solutions to help ensure the quality of peptide therapeutics. Dr Caitlin Hanna from Waters will describe a reverse-phase LC-UV method development case studies for the impurity analysis of fatty-acid modified GLP-1 receptor agonists.
Key learning objectives:
- Understand the key analytical challenges and regulatory expectations for peptide quality assessment
- Learn about USP products and solutions for peptide impurity analysis
- Explore column screening and method development considerations for the analysis of fatty-acid modified GLP-1 receptor agonists
