Post-Conference Comparability Day

Strategic Planning for Comparability Studies

Demonstrating comparability is one of the greatest challenges for gene therapy developers. With changing production sites, processes, and evolving analytical methods, comparability or bridging studies must be performed as these methods progress.


The post-conference comparability day will discuss the importance of:

  • Encouraging an ongoing dialogue between a company’s regulatory affairs department and the respective health authorities
  • Clarifying how many retains of samples were set aside to support clinical programs
  • Encouraging ongoing negotiation between various departments, such as working with manufacturing to reserve quantities of early phase materials in advance with the anticipation that the health authorities are going to require retrospective testing
  • Planning for the fixed volume required for analytical testing
  • Analytical comparability vs clinical comparability: release and/or characterization methods
