  • "Mechanistic Translational PK/RO Modeling vs MABEL to Predict First-in-Human Dose for Bispecific & Multispecific Antibodies"

Oleg Demin Jr will cover the following points:

  • Minimal Anticipated Biological Effect Level (MABEL) approach is recommended to select clinical starting dose for mAbs and multispecific biotherapeutics.  
  • For many immune-activating antibodies first-in-human (FIH) doses identified by MABEL were low and required many dose escalation steps exposing patients to sub-therapeutic doses.  
  • Mechanistic translational PK/RO modeling predicts FIH dose for multispecific antibodies taking into account specific features of the candidate (affinity, avidity, targets), its concentration in tumor, and mechanism of action (trimers and other complexes in immunological synapse responsible for effect, bell-shaped dose dependence, etc.): a case of HPN536, a T-cell engager targeting mesothelin.
