Population Pharmacokinetics of ABT-806, an Investigational Anti-Epidermal Growth Factor Receptor (EGFR) Monoclonal Antibody, in Advanced Solid Tumor Types Likely to Either Over-Express Wild-Type EGFR or Express Variant III Mutant EGFR

摘要

Background and Objectives ABT-806 is a veneered 'humanized' recombinant IgG1 kappa antibody that is specific for a unique epitope of human epidermal growth factor receptor (EGFR) expressed only on tumor cells with the EGFRde2-7 (EGFRvIII) deletion mutant as well as tumors with wild-type amplified receptors. We aimed to develop a population pharmacokinetic model of ABT-806 in cancer patients, and to evaluate fixed versus body weight-based dosing regimens.
