Addressing the challenges of purification & quality control in gene therapy

Recombinant Adeno Associated Virus (rAAV) vectors are one of the most promising mechanisms for therapeutic gene delivery. However, most industrial cell lines exhibit inefficient gene packaging which results in a heterogenous population of vectors composed of empty, partially-loaded, and fully-loaded species. Purifying, identifying, and quantifying these different species is vital from a production and quality control standpoint, since improperly loaded viral capsids do not produce the desired therapeutic effect but may still elicit an unintended immune response.

In this Beckman Coulter Life Sciences webinar, our panelists will focus on several pertinent topics in rAAV process development including current challenges, technologies for overcoming quality control hurdles, best practices for downstream processing, as well as discuss the current trends and future outlook of this rapidly growing therapeutic frontier.

Attendees will learn:

• Understand the challenges of differing serotypes in rAAV production and quality control
• Understand the commonly used characterization techniques for AAV capsids
• Understand the basics of Analytical Ultracentrifugation (AUC) and how it is used to characterize empty, full, and intermediate AAV capsids
• Learn about best practices in Density Gradient Ultracentrifugation (DGUC) to achieve highest purity in gene therapy products

Further panellists to be announced soon.

Klaus Richter PhD

Group Leader AUC, Coriolis Pharma

Dr. Klaus Richter is the leader of the AUC group at Coriolis Pharma, which is dedicated to the biophysical characterization of drug products and drug substances ranging from small molecules and peptides to viral particles and liposomes. He is a biochemist by training and received a Ph.D. from Technical University of Munich in the field of protein characterization and worked for several years in the area of structure-function and structure-activity relationships of pharmaceutically relevant proteins before joining Coriolis Pharma. Klaus obtained his Habilitation in 2012 and is the (co-) author of more than 70 publications in the field of protein characterization with diverse biophysical methods, in many cases applying analytical ultracentrifugation (AUC) as a tool to investigate protein structure, protein interaction and stability.

Shawn Sternisha PhD

Senior Field Applications Scientist, Beckman Coulter Life Sciences

Shawn Sternisha is currently a Senior Field Applications Scientist in the Biotechnology Business Unit at Beckman Coulter Life Sciences where he develops applications and supports centrifuge product lines. Shawn attended Illinois State University for his undergraduate studies and went on to earn his Ph.D. in Biochemistry at Florida State University. His doctoral research was focused on understanding how glucokinase regulates glucose homeostasis at the molecular level. Shawn has also previously worked at GlaxoSmithKline where he was involved in investigating novel imaging modalities for monitoring mammalian cell cultures. Shawn is broadly interested in enzyme structure-function relationships and mechanisms of action, cell and gene therapy, and expanding applications of biochemical and biophysical techniques (namely Analytical Ultracentrifugation). Shawn currently resides in Miami, FL with his fiancée Patty and their dog Ruby. In his free time, he enjoys cooking, running, traveling, and learning Spanish.
