Improved analytical methods are helping improve the understanding of capsid heterogeneity in adeno-associated virus (AAV) therapeutic preparations. This understanding allows the development of manufacturing processes that produce AAV therapeutics with fewer non-functional capsids.
In this webinar, the speakers will present the results of a five-arm AAV9 comparability protocol that includes four alternative two-column downstream processes at 50-L scale and an ultracentrifugation (UC) process at 200-L scale. The UC process is the gold standard for functional capsid purification.
The expert speakers will outline simplified processes for both the capture and the empty/full (E/F) separation steps, including various combinations of cation exchange chromatography (CEX) and anion exchange chromatography (AEX) monoliths with different gradient types, as well as a process using an affinity resin and AEX monolith.

What You Will Learn
Attendees will learn about:
- Two-column processes producing 90 to 93 percent full capsids at drug substance compared to 94 percent for the ultracentrifugation (UC) process based on sedimentation velocity analytical ultracentrifugation (SV-AUC) analyses
- How 84 to 87 percent of the encapsidated deoxyribonucleic acid (DNA) sequences in the drug-substances were full-length expression cassettes capable of expressing enhanced green fluorescent protein (eGFP) based on long-read next-generation sequencing (NGS)
- The potencies of the drug substances from two-column processes being equivalent and potentially greater than the UC-purified drug substance
- How the two-column processes can be more readily scaled to 500-L and 1000-L bioreactors than the UC process
