Event Overview:


Join us for a focused, insightful webinar exploring the decision to change your critical starting material from traditional plasmid DNA (pDNA) to synthetic cell-free DNA echnology. For innovators developing cutting-edge nucleic acid and viral vector-based therapies, the purity, speed, and scalability of starting materials are paramount. Host Amy Walker, Ph.D., COO of 4basebio, will lead a discussion with distinguished guest speaker Jenny Mellquist, Ph.D., about the compelling drivers for making this strategic change, from overcoming pDNA manufacturing bottlenecks to achieving higher product purity, and the impact on patient safety. We will highlight key regulatory hurdles and requirements, and outline the practical steps and data packages needed to successfully implement the switch of critical starting material.


Key Learning Objectives:

  • Identify the critical regulatory considerations and necessary CMC documentation required by agencies like the FDA when substituting a core starting material.
  • Review the practical requirements and data needed to successfully plan and execute the change in a cGMP environment.
  • Understand the technical and logistical advantages transitioning from plasmid DNA to cell-free DNA technology for critical starting materials in advanced therapies.

Who Should Attend:

  • CMC Leaders
  • Manufacturing Directors
  • CSO
