Upstream Bioprocess for Adenovirus Vectors

Adenovirus vectors (AdV) constitute very powerful vehicles for gene transfer with applications in vaccination, cancer treatment, and many monogenic and acquired diseases. To cope with the need for significant amounts of clinical grade material, efficient and robust bioprocesses compliant with good manufacturing practices need to be established. This chapter reviews AdV production processes, discussing how producer cell line specifications, viral construction, cell culture characteristics, and bioprocess parameters can impact the overall production yields. Further considerations for upstream processing to meet the specifications for clinical product release are also presented in this chapter. Finally, future directions toward a simplified and streamlined production process are discussed in light of state-of-the-art AdV manufacturing.
