Criteria

Inclusion Criteria:

• Subjects must have signed an approved informed consent.

• Histologically confirmed diagnosis of advanced adenocarcinoma of the colon or rectum, with KRAS wild type on mutational analysis.

• No prior chemotherapy for metastatic disease (chemotherapy naive). Prior adjuvant therapy with 5FU/LV or IFL (irinotecan, fluorouracilis, and leucovorin (folinic acid)) permitted if completed at least six months prior to entering this study.

• Measurable disease by RECIST criteria as defined in Section 3.3.1.

• Subjects for whom tumor tissue is available for IHC ( Immunohistochemistry) testing for EGFR expression.

• ECOG (Eastern Cooperative Oncology Group) Performance Status 0-1.

• Recovery in full from any previous surgical procedure.

• Expected survival greater than 12 weeks.

• Subjects at least 18 years of age.

• Women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 4 weeks after the study in such a manner that the risk of pregnancy is minimized. WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 72 hours prior to the start of study medication.

• Adequate hematologic function defined by an absolute neutrophil count (ANC) > 1,500/mm3, a platelet count > 100,000/mm3 .

• Adequate hepatic function defined by a total bilirubin level no greater than 2.0 times the upper limit of normal (ULN) and AST (Aspartate Aminotransferase) and ALT (alanine transaminase) levels noo greater than 2.5 times the ULN (AST and ALT levels no greater than 5 times the ULN in the presence of liver metastases).

• Adequate renal function defined by a serum creatinine level no greater than 1.5 times the ULN.

Exclusion Criteria:

• WOCBP who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period and for up to 4 weeks after the study.

• Women who are pregnant or breastfeeding.

• Women with a positive pregnancy test on enrollment or prior to study drug administration.

• Sexually active fertile men not using effective birth control if their partners are women of child-bearing potential.

• Subjects with > Grade 1 neuropathy.

• Any active or uncontrolled infection.

• History of myocardial infarction within the previous six months or current clinical evidence of congestive heart failure.

• History of any other cancer (except nonmelanoma skin cancer or carcinoma in situ of the cervix) unless in complete remission and off all therapy for that cancer for at least 5 years.

• Central nervous system metastases.

• Pregnant or lactating women. Men and women of reproductive potential must agree to use an effective contraceptive method.

• Medical or psychiatric disorders that would interfere with informed consent or make them a poor risk for participation in this trial.

• Prior allergic reaction to chimerized or murine monoclonal antibody therapy or documented presence of human anti-mouse antibodies (HAMA).

• Subjects receiving a prior investigational agent within 30 days.

• Prior therapy with oxaliplatin, cetuximab, or prior therapy that targets the EGF ( epidermal growth factor) pathway.

• Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious disease) illness must not be enrolled into this study.

• Mutation in the KRAS gene
