Human Pathobiology

The principle that drug discovery should be grounded in human disease biology rather than animal model biology. A central theme of Session I, championed especially by Alistair Henry (UCB).

The Argument

  • The mouse will keep telling you a clean, wrong story
  • F: the human peripheral blood signature showed IL-17F driving the late phase of inflammation — mouse showed nothing
  • Bimekizumab was built because human pathobiology won the internal argument at UCB against affinities and receptor stoichiometry
  • With FDA evaluation of New Approach Methods (NAMs), this stops being aspirational

Tools

  • Organoids and tissue explants
  • Patient-derived material
  • Human peripheral blood profiling
  • Transcriptome back-translation from treated patients
  • iPSC-derived neurons (used in SARM1 and Alzheimer’s studies)
