Primary Outcome Measures
NameTimeMethod
To demonstrate uptake of 89Zr-cetuximab in non-hepatic tumor lesions using immuno-PET when administered during the loading dose of cetuximab. <br><br /><br /><br>Part two - Primary objective:<br /><br>To investigate whether there is an association between uptake of cetuximab in non-hepatic tumor lesions and response according to RECIST 1.1 criteria.
Secondary Outcome Measures
NameTimeMethod
1. To investigate whether there is an association between levels of uptake of 89Zr-cetuximab in the liver compared to levels of uptake in non-hepatic tumor lesions;<br /><br>2. To explore whether the response observed on [18F]-FDG-PET can serve as an early response marker for future response to targeted therapy according to RECIST 1.1;<br /><br>3. To explore whether there is an association between 89Zr-cetuximab uptake in non-hepatic tumor lesions, grade of skin toxicity and response according to RECIST 1.1.
