6. Tumor tissue specimen (formalin-fixed, paraffin-embedded block) preferably from primary resection and/or if available from a surgical sample from metastatic site must be available for central laboratory based ανβ6 integrin expression analysis. (No Fine Needle Aspiration [FNA] will be accepted);
7. At least 1 radiographically documented measurable lesion in a previously non-irradiated area according to RECIST (Version 1.1), i.e., this lesion must be adequately measurable in at least 1 dimension (longest diameter to be recorded) as ≥2 cm by conventional techniques or ≥1 cm by spiral CT scan;

2. Prior anti-EGFR or other targeted therapy;
3. Prior chemotherapy of the colorectal cancer, except for (neo) adjuvant therapy completed at least 6 months before randomization;

5. Investigational drug treatment for the treatment of malignancies in the past;
6. Concurrent participation in another interventional clinical study;
7. Pregnancy (exclusion confirmed with beta-hCG test) or lactation;
8. Any history or evidence of brain metastases or leptomeningeal metastases;
9. History of secondary malignancy within the past 5 years, except for basal cell carcinoma or carcinoma in situ of the cervix uteri, if treated with curative intent;
10. Concomitant chronic systemic immune or hormone therapy not indicated in this study protocol (except for physiologic replacement; steroids up to 10 mg per day of prednisone equivalent or topical and inhaled steroids are allowed);
11. Clinically relevant coronary artery disease (New York Heart Association [NYHA] functional angina classification III/IV), congestive heart failure (NYHA III/IV), or clinically relevant cardiomyopathy;

13. History of myocardial infarction in the last 12 months, or a high risk of uncontrolled arrhythmia, coagulation disorder associated with bleeding or recurrent thrombotic events, with the exception of arterial fibrillation treated with anti-coagulants;
14. Recent peptic ulcer disease (endoscopically proven) within 6 months of randomization, chronic inflammatory bowel disease, or acute/chronic ileus;
15. Active infection (requiring IV antibiotics and/or antiviral therapy), including active tuberculosis, active or chronic Hepatitis B or C, or ongoing HIV infection, AIDS;
16. Presence of any contra-indications or known hypersensitivity to treatment with abituzumab, cetuximab, and FOLFIRI, or to any of the excipients of these drugs;
