团体讨论

These interactive discussion groups are open to all attendees, speakers, sponsors, & exhibitors. Participants choose a specific breakout discussion group to join. Each group has a moderator to ensure focused discussions around key issues within the topic. This format allows participants to meet potential collaborators, share examples from their work, vet ideas with peers, and be part of a group problem-solving endeavor. The discussions provide an informal exchange of ideas and are not meant to be a corporate or specific product discussion.

Immunogenicity Prediction and Control

Viability of Immune Tolerance Strategies for the Treatment of Human Disease

Moderator: Stephen Miller, PhD, Professor of Microbiology-Immunology, Feinberg School of Medicine, Northwestern University

  • What are the appropriate disease indications for testing tolerance therapy in initial clinical trials?
  • What factors are important in developing the ideal approach for tolerance induction?

Development of Robust T Cell Response Immunogenicity Prediction Assay

Moderator: Karen Liao, MD, Investigator, GSK Associate Fellow, GlaxoSmithKline
