A Whole Body Physiologically-based Pharmacokinetic Model for Antibody Drug Conjugates—Model Development and Validation in Rat
Mechanistic Modeling of Antibody Drug Conjugate Pharmacokinetics
Antibody Drug Conjugates (ADCs) are constructed by attaching a small molecule drug to an antibody via a linker. The antibody selectively targets tumor cells and releases the cytotoxic drug within the cells to kill cancerous cells while sparing healthy tissue. Although some ADCs have been approved, many unanswered questions remain, such as drug-drug interactions (DDIs) and […]

Prediction of the Pharmacokinetics, Pharmacodynamics, and Efficacy of a Monoclonal Antibody, Using a Physiologically-based Pharmacokinetic FcRn Model
Although advantages of physiologically based pharmacokinetic models (PBPK) are now well established, PBPK models that are linked to pharmacodynamic (PD) models to predict pharmacokinetics (PK), PD, and efficacy of monoclonal antibodies (mAbs) in humans are uncommon. The aim of this study was to develop a PD model that could be linked to a physiologically based mechanistic FcRn model to predict PK, PD, and efficacy of efalizumab. The mechanistic FcRn model for mAbs with target-mediated drug disposition within […]

Simulation of Monoclonal Antibody Pharmacokinetics in Humans Using a Minimal Physiologically-based Model
Compared to small chemical molecules, antibodies and Fc-containing derivatives (mAbs) have unique pharmacokinetic behavior characterized by relatively poor cellular permeability, minimal renal filtration, binding to FcRn, target-mediated drug disposition, and disposition via lymph. A minimal physiologically based pharmacokinetic (PBPK) model to describe the pharmacokinetics of mAbs in humans was developed. Within the model, the body is divided into three physiological compartments; plasma, a single tissue compartment and lymph. The […]

Incorporating Target Shedding into a Minimal PBPK-TMDD Model for Monoclonal Antibodies
Shedding of a pharmacological target from cells, giving rise to a soluble target that can also bind therapeutic proteins, is a common phenomenon. In this study, a minimal physiologically based pharmacokinetic model was used to simulate the pharmacokinetics of trastuzumab and the simultaneous binding of the compound to soluble (in blood and tissue interstitial space) and membrane-bound (in the tissue interstitial space) forms of […]

Accounting for Transporters in Renal Clearance: Towards a Mechanistic Kidney Model (Mech KiM)
The impact of transporters in modulating the disposition of drugs in the liver and their passage across the gut wall has received much more attention than their role in renal excretion, despite the fact that 25–30 % of drugs are cleared predominantly by renal clearance and renal transporters contribute significantly to this process. Thus there […]
