- Any uncontrolled concomitant disease (e.g., uncontrolled diabetes) or medical history (e.g., organ transplantation) which, according to the opinion of the investigator, may interfere with the interpretation of the study results.
- Any comorbidity or situation which, according to the opinion of the investigator, could increase the risk of toxicity (e.g., Dihydropyrimidine dehydrogenase deficiency).
- Chronic or active HIV, HBV or HCV infections.
- Severe and\or not healed wound.
- Any active infection requiring systemic treatment, or any uncontrolled infection within 14 days before randomization.
- Other concomitant malignancy or history of cancer (except carcinoma in situ of the cervix, or non melanoma skin cancer, with curative intent treatment), except when considered in complete remission for at least 5 years before randomization.

|Principal investigator||David MALKA, Dr|
|Description||Patients are randomised to modified FOLFOX6 (oxaliplatin 85 mg/m2, FA 400 mg/m², FU 400 mg/m² bolus then 2400 mg/m² over 46 hr) alone or combined to either panitumumab (6 mg/kg) or AMG 102 (10 mg/kg), every two weeks until unacceptable toxicity or disease progression. Judgment criteria include 4-month progression-free survival (PFS) rate (primary endpoint), OS, objective response rate, and safety. Ancillary studies aim to identify candidate predictive and prognostic biomarkers among functional of molecular alterations of the EGFR/RAS/RAF and HGF/c-Met pathways, and to monitor circulating tumour cells and circulating immune cells (myeloid derived suppressor cells, NK cells) in sequential blood samples taken at baseline and through the study treatment. A total of 165 pts will be enrolled (Fleming's one-step design)|
