A 3-Day Workshop on Monoclonal Antibody Pharmacokinetics and Pharmacodynamics

Thursday, May 16 - Saturday, May 18, 2019
Niagara Falls, NY

This workshop has been designed to provide a detailed discussion of issues relevant to the pharmacokinetic / pharmacodynamic (PK/PD) modeling of antibody drugs, and to provide a series of “hands-on” case studies describing the development and application of mathematical models to simulate and characterize antibody PK/PD.

Workshop Overview

Lectures will address primary determinants of antibody pharmacokinetics (PK) and pharmacodynamics (PD), the design and
implementation of pre-clinical investigations of antibody PK/PD, and state-of-the-art mathematical models to characterize and predict antibody PK and PD. Case studies, featuring use of the ADAPT program, will include application of models for antibody-ligand binding and disposition, target-mediated disposition, and physiologically-based pharmacokinetic modeling. Special emphasis is placed on discussion of the role of FcRn on the absorption, distribution, and elimination of antibodies, on the mathematical modeling of target-mediated antibody disposition, and on physiologically-based modeling of antibody pharmacokinetics. The workshop content is provided as a combination of formal lectures and informal review sessions.

Subjects that will be presented include:

  • Determinants of antibody pharmacokinetics and pharmacodynamics: mechanisms of antibody elimination, the role of
    convection in the kinetics of antibody distribution, the role of FcRn in antibody absorption, distribution, and elimination
  • Interspecies Scaling of Antibody PK: considerations and examples involving the use of allometric methods to scale protein pharmacokinetics from pre-clinical models to humans
  • Drug-drug interactions: mechanistic considerations and examples for drug-drug interactions involving monoclonal antibodies, including consideration of antibodies as perpetrators and as victims of DDI
  • Target-Mediated Antibody Disposition: modeling, implications for interspecies scaling, implications for First-in-Human studies
  • Modeling of bimolecular antibody-ligand interaction
  • Physiologically-based pharmacokinetic modeling: Incorporation of FcRn-mediated antibody transport in PBPK models, incorporation of target-mediated disposition, use of PBPK and preclinical data to predict antibody disposition in humans
