Pharmacokinetics and Metabolic Activation of Capecitabine

Pharmacokinetics and Metabolic Activation of Capecitabine When Given Concomitantly With Oxaliplatin and the Monoclonal Antibody Cetuximab

The objective of this pharmacokinetic study is to exclude a possible influence of CETUX on the plasma disposition and metabolic activation of Capecitabine (CCB) and when this regimen is given combined with Oxaliplatin (OxPt).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Influence of Cetuximab on metabolic activation of Capecitabine
Time Frame: 9 weeks
Curve fitting of drug and metabolite concentrations will be performed. For pharmacokinetic modelling of CCB and metabolites, a non-compartment model for extravascular input will be used. For calculation of AUC and AUMC the linear trapezoid rule will be applied for the ascending part of the concentraion-time curve and the log-linear trapezoidal rule for the descending part of the concentration-time curve.
9 weeks
