Detailed Description
Colorectal carcinoma (CRC) is the third most common form of cancer worldwide and remains a leading malignancy both in incidence and mortality.
In the light of existing knowledge, the investigators propose a phase II open label, two arm study in patients presenting with K-Ras wild-type metastatic colorectal tumours in the first line setting. The standard combination of irinotecan plus infusional 5-FU/LV (FOLFIRI) and cetuximab will be given to all patients entering the study. As the investigators hypothesize that increasing the dose of cetuximab might increase the intensity of skin reactions that directly correlates with outcome, in patients experiencing no skin toxicity, the dose of cetuximab will be escalated from 250 mg/m2 to 350 mg/m2 and then up to 500 mg/m2, in order to better define the effect of dose escalation in the first-line setting in a K-Ras wild type tumour population and in an attempt to increase efficacy.
Pharmacokinetic studies will be performed to document PK parameters of cetuximab in patients from both arms in selected centers.
Translational research studies are planned for all patients. Some more in depth molecular testing will be performed in a subset of patients from whom three serial tissue samples from accessible metastases by biopsy are available.
