Implementation of QbD for the development of a vaccine candidate

This case study provides an example of how Quality by Design (QbD) principles were applied to accelerate process development to manufacture a vaccine candidate at commercial scale. By leveraging an existing manufacturing platform process, a risk assessment was used to differentiate process parameters that could be defined using a combination of scientific and historical manufacturing knowledge from those that merited additional process characterization by experimentation. Select parameters, and their interactions, were evaluated by a Design of Experiment (DoE) series. This systematic approach required less time and fewer resources and resulted in the definition of a reliable and robust manufacturing process that meets regulatory requirements.
