Webinar Date/Time: Friday, March 24, 2023 at 11am EST | 10am CST | 8am PST

In this webcast, panel speakers will discuss challenges. From both a drug development and also clinical perspective. We will learn why analytical characterization of material is important at every step to making sure the critical quality attributes (CQA) stay within a threshold, within specifications and guidance, are identify their potential Chemistry, Manufacturing and Controls (CMC) issues, which need to be tackled during the early manufacturing process development.

Event Overview:

In this webinar learn that manufacturing for viral vectors complexity requires components that are not needed in stable, recombinant protein–expressing production systems. Examples are lipid- or polymer-based transfection reagents and lysis buffers. Another added obstacle, overall yields of functional capsids containing the desired genetic payload is most often lower than required, creating calls to move to higher scales of production to compensate. Furthermore, transient transfection is frequently employed constituting a single-run bespoke cell line for each manufacturing lane. A more robust, scalable, and higher density suite of methods is therefore highly desirable.

Key Learning Objectives

  • Achieving high-yield manufacturing of plasmids that contain difficult genetic payloads (gene-of-interest size, base composition, toxicity, use of selection markers)
  • Relative importance of these challenges when pursuing large plasmid sizes, for example, leakey promoters that lead to pre-mature protein expression upstream or losses during alkaline lysis. Can we discount for repeated sequences such as ITRs and polyA tails that are more prone to deletion and recombination events?
  • Are there successful ways to navigate these by balancing buffer volumes, buffer contact time, reducing sheer, using well characterized pHelper and pREPCAP plasmids
  • How automation might decrease manual labor, however integration isn’t easy – problems exist in communication with reactors, analyzers and pre-existing software.
  • Pros and cons for industry to develop either a series of dedicated fit-for-one purpose optimized platforms, versus attempts at a “flexible” platform that can manage a wide ranch of vector types which might then be “standardized” industry-wide.

Who Should Attend

  • Advanced therapy medicinal products scientists
  • Cell and gene therapy manufacturers
  • Regulatory and government relations personnel
  • Viral vector manufacturers
  • Oncologists and immunologists
  • Potency assay researchers
  • CAR-T and blood disorder physicians
