SC 3 - Accelerated Stability Testing of Biologics

Monday, August 3
9:00—11:30 am

This short course will aim to guide the researcher in designing studies for accelerated stability testing of biologics. The course will begin with basic underlying concepts governing protein drug product stability, and focus on design principles for measuring stress and accelerated stability testing of not only the protein of interest, but also of excipients and primary packaging components. Strategies to handle complexities arising from their interactions will also be discussed.

  • Attributes of a successful protein drug product
  • Modes of protein degradation: Conformational stability, colloidal stability and chemical stability
  • Chemical degradation reaction
  • Real-time/accelerated/stress stability testing: Rational design of stability conditions
  • Stressors for evaluating protein stability
  • Developing predictive and correlative tools: Utility, desired features and examples
  • Excipients
  • Primary packaging
  • Application of novel tools, DoE and practical insight from case studies for developing robust protein formulations


Jan JezekJan Jezek, Ph.D., CSO, Development, Arecor Ltd.

Jan Jezek, the principal inventor of the core protein stabilisation technologies, is a biochemist with a strong background in physical chemistry. Currently responsible for R&D activities, platform development and technical IP support in the field of stabilisation of biologics. He played a crucial role in the development of stabilising technologies for commercially important proteins that allow preservation of protein structure and biological activity during sterilisation by gamma radiation and during long-term storage at ambient temperature. Lead successful grant funded projects with TSB funding. Previously, a Principal Scientist at Insense Limited, he was responsible for development of novel medical devices from concept to market. Dr. Jezek holds a joint Doctorate from the University of Bedfordshire and the University of Chemical technology, Prague. He is a member of the Scientific Advisory Board of the Centre of Excellence in Biopharmaceuticals (University of Manchester). He is also a committee member of the Formulation Science & Technology Group (FSTG) at the Royal Society of Chemistry.
