Application of Knockout Mouse Models to Investigate the Influence of FcγR on the Pharmacokinetics and Anti-platelet Effects of MWReg30, a Monoclonal Anti-GPIIb Antibody

By

This work evaluates the influence of FcγR on the pharmacokinetics and pharmacodynamics of a rat anti-integrin-αIIb IgG1 monoclonal antibody, MWReg30, in mice. The pharmacokinetics and pharmacodynamics of MWReg30 were investigated in C57BL/6 control mice, FcγRI/RIII knockout mice, and FcγRIIb knockout mice, following intravenous doses of 0.04-0.4mg/kg. MWReg30 treatment resulted in a dose-dependent induction of thrombocytopenia … Continued

Saturable Drug Absorption

By

Drug absorption is the process by which a drug molecule moves from the site of administration to the systemic circulation. Following intravenous administration, there is no absorption process since the drug is directly introduced into the blood stream. However, for oral, intramuscular, subcutaneous, sublingual, buccal, transdermal, (and many other routes), there will be an absorption … Continued

Systems Pharmacology of the Nerve Growth Factor Pathway: Use of a Systems Biology Model for the Identification of Key Drug Targets Using Sensitivity Analysis and the Integration of Physiology and Pharmacology

By

The nerve growth factor (NGF) pathway is of great interest as a potential source of drug targets, for example in the management of certain types of pain. However, selecting targets from this pathway either by intuition or by non-contextual measures is likely to be challenging. An alternative approach is to construct a mathematical model of … Continued

Systems Pharmacology for Drug Discovery and Development: Paradigm Shift or Flash in the Pan?

By

Systems pharmacology is an emerging approach that sets out to use quantitative concepts rooted in the synergy between modeling and simulation on one hand and large-scale data collection and analysis on the other to investigate biological systems and design therapeutic interventions. Interest in this field has recently increased substantially, but so have perceived challenges and … Continued

Nonlinear PK: What Does That Mean?

By

You may come across a phrase like the following and wonder what it means: “… this drug exhibits nonlinear pharmacokinetics …”. An example of a drug that has nonlinear pharmacokinetics (PK) is erythropoietin or EPO. You may have heard about EPO in the context of sports because it is a performance enhancing drug (PED). EPO … Continued

What is Quantification Anyway?

By

Bioanalytical analysis is a fundamental tool for the pharmacokineticist. The results of a bioanalysis are the source data for all pharmacokinetic work. Thus a clear understanding of the methodologies and challenges associated with the bioanalytical analysis science is of great benefit to a pharmacokineticist. As an example, I was recently working on the development of … Continued
