Pharmacokinetic (PK) and pharmacodynamic (PD) models seek to describe the
temporal pattern of drug exposures and their associated pharmacological effects
produced at micro- and macro-scales of organization. Antibody-based drugs have
been developed for a large variety of diseases, with effects exhibited through a
comprehensive range of mechanisms of action. Mechanism-based PK/PD and systems
pharmacology models can play a major role in elucidating and integrating complex
antibody pharmacological properties, such as nonlinear disposition and dynamical
intracellular signaling pathways triggered by ligation to their cognate targets.
Such complexities can be addressed through the use of robust computational
modeling techniques that have proven powerful tools for pragmatic
characterization of experimental data and for theoretical exploration of antibody
efficacy and adverse effects. The primary objectives of such multi-scale
mathematical models are to generate and test competing hypotheses and to predict
clinical outcomes. In this review, relevant systems pharmacology and enhanced PD
(ePD) models that are used as predictive tools for antibody-based drug action are
reported. Their common conceptual features are highlighted, along with approaches
used for modeling preclinical and clinically available data. Key examples
illustrate how systems pharmacology and ePD models codify the interplay among
complex biology, drug concentrations, and pharmacological effects. New hybrid
modeling concepts that bridge cutting-edge systems pharmacology models with
established PK/ePD models will be needed to anticipate antibody effects on
disease in subpopulations and individual patients.
