SC 6: Accelerated Stability Testing of Biologics

Tuesday, August 19, 2014 | 6:00 – 8:30pm

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.

Agenda at a Glance:

  • 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
    • Temperature: Arrhenius and non-Arrhenius kinetics
    • pH: coupled effects of pH and buffers
    • Interface: effects of protein stability: solid/liquid, liquid/liquid and liquid/gas
    • Oxidizers
  • Developing predictive and correlative tools: utility, desired features and examples
  • Excipients
    • Degradation mechanisms
    • Impact on protein stability
    • Factors to consider during stress/accelerated testing
  • Primary packaging
    • Accelerated stability testing
    • Extractable/leachables
