  • Natalie Fekete Manager - Science & Industry Affairs, Alliance for Regenerative Medicine

Synopsis

Roundtable discussions include a larger focus on group discussion. A moderator will introduce the session topic and attendees then split into groups to discuss a series of predetermined agenda points. At the end, all groups report back on their discussions, and findings are collated.

This roundtable will cover:

  • Outlining the major changes made to the new FDA guidance to understand the reasoning behind the updates
  • Making comparisons with the previous guidance and identifying significant shifts or emphasis changes
  • Discussing how the new guidelines should be interpreted and implemented to guide novel assay design approaches
