Recorded: March 2022

This webinar will highlight our multifaceted approach to downstream AAV production and purification, including separating the genome-containing (full) from genome-free (empty) AAV capsids and a selection of innovative purification solutions to improve yield, purity, and throughput. 

Key messages on Downstream AAV Production:

  • The key parameters to consider for optimizing downstream AAV production and purification: Serotype, Upstream harvest yields, Empty:Full ratios, recovery, and our approach to purification
  • Showcase our selection of DSP purification techniques in our toolbox 
  • Platform improvements to be aligned with the latest technological advancements and driven through both external collaborations and internal innovation
  • Use of BIA Separations’ monoliths as a solution to the challenge of separating full from empty AAV capsids
  • Use of BIA Separations’ new CIMasphere technology for the removal of host cell DNA-related impurities

Agenda: 

  1. What is the current industry-wide understanding of separating Empty and full capsids? 
    • The key parameters for consideration (including regulatory stance) and why they are so important
    • Differences in purification methods (based on serotype) and their scalability (UC, chromo)
    • Product-specific impurity removal
  2. What is our current approach to DSP purification
    • Platform process and data to assess fit
    • High-throughput technology in combination with DoE to optimize key parameters and increase pace 
    • Impact of resin low resolution between empty and full capsids 
    • Introduce BIA and the importance of collaboration
  3. What are BIA Separations monolith and CIMasphere technology, and how can we purify clinical-quality AAVs? 
    • Introduction to BIA Separations and their products
      • Use of monoliths in gene therapy commercial manufacturing 
      • Monolith architecture for preparative and analytical applications 
      • What makes monoliths suited to the challenging requirements of purifying large biomolecules such as AAVs? 
      • Chromatin’s effect on AAV purification and how the CIMasphere technology may help
    • Pharmaron’s Feasibility study and optimization data
      • Optimization study to tune running conditions for cation and anion monolithic purification
      • CIMasphere feasibility study to benchmark BIA Separations’ cornerstone platform for purification of AAVs
