Title: Benefits of mechanism-based modeling to characterize the pharmacokinetic properties of therapeutic monoclonal antibodies * Bioinformatics Affinity Seminar

Time: Wed, Apr 3, 2013, 10am

Place: MPI für Molekulare Pflanzenphysiologie, Room 0.21 in The Box

Therapeutic monoclonal antibodies (mAbs) are mainly engineered immunoglobulins type G (IgG) which are proteins directed against a specific target. They are essential assets in the treatment of cancer, inflammatory and infectious diseases. It is important to understand their pharmacokinetic properties, i.e. absorption, distribution, metabolism and excretion (ADME) in order to recommend safe and efficacious dosing regimens. These properties are commonly characterized with an empiric compartmental approach applied to the plasma data. However, there is a high interest in developing predictive mechanistic pharmacokinetic models describing the detailed knowledge of the molecular processes involved in the ADME of mAbs. Physiologically-based pharmacokinetic (PBPK) models represent a primary choice because they allow integrating physiological data (e.g. plasma and lymph flows, plasma and tissue volumes) and in vivo data (e.g. plasma and tissue concentrations). So far, existing PBPK models developed in mice are not satisfactory because they either do not take into account the impact of endogenous immunoglobulins type G or tissue data for model building. We developed a PBPK model for mAbs, in mice, in the absence of target which accounts for plasma and tissue data and the most relevant mechanism governing their ADME properties. We applied model reduction techniques in order to derive a physiology-based-low-dimensional model and draw a parallel with the empirical approach. This is joint work with Prof. Wilhelm Huisinga.
