Abstract

Currently, more than 350 monoclonal antibodies (mAbs) and mAb derivatives are under development as therapeutics. The prediction of mAb pharmacokinetics (PK)/pharmacodynamics (PD) plays a key role in starting dose selection for first-in-human (FIH) studies. This article presents a brief overview of the biology and mechanisms of absorption, distribution, metabolism and excretion (ADME) for mAbs. In addition, a detailed review of mAb human PK/PD prediction from nonclinical data is provided, including allometry for mAbs with linear or nonlinear PK, species-invariant time method, physiologically based PK (PBPK) modeling and target-mediated drug disposition (TMDD) model, bioavailability projection and immunogenicity impact on PK prediction. Finally, from an industry perspective a decision tree of mAb human PK projection is proposed to facilitate drug development. Copyright © 2015 John Wiley & Sons, Ltd.
