• All participants must express the wild-type form of the gene KRAS.
• Measurable disease according to RECIST (Response Evaluation Criteria In Solid Tumors) criteria, Version 1.1.
• Male or female >= to 18 years of age.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
• Resolution of any toxic effects of prior therapy (except alopecia) to NCI CTCAE, Version 4.0, grade = to 9.0 g/dL (transfusion and/or growth factor support allowed).
• Absolute neutrophil count (ANC) >= to 1.5 x 10^9/L.
• Platelet count >= to 75 x 10^9/L.
• Serum creatinine = to 60 mL/min.
• Alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase <= to 2.5 x ULN in subjects with no liver metastasis and <= to 5.0 x ULN in participants with liver metastasis.
• Total bilirubin <= to 1.5 x ULN (<= to 4 x ULN and direct bilirubin <= to 1.5 x ULN is acceptable for subjects with Gilbert's syndrome).
• Male and female participants of child-bearing potential must agree to use double-barrier contraceptive measures, oral contraception, or avoidance of intercourse during the study and for 90 days after last investigational drug dose received.
• All female participants of childbearing potential must each have a negative pregnancy test (serum or urine) result before initiating study treatment.
• Participants must be fully informed about their illness and the investigational nature of the study protocol (including foreseeable risks and possible side effects) and must sign and date an Independent Ethics Committee (IEC) or Institutional Review Board (IRB)-approved informed consent form (ICF) (including HIPAA authorization, if applicable) before performance of any study specific procedures or tests.

Exclusion Criteria

• Prior therapy with an Epidermal Growth Factor Receptor (EGFR) inhibitor.
• History of malignancy other than CRC, unless there is an exception that the malignancy has been cured and no tumor-specific treatment for the malignancy has been administered within the 5 years prior to initiation of study treatment (participants with a history of basal cell carcinoma or benign tumor of cervix can be enrolled if diagnosis and treatment occurred less than 3 years prior to randomization).
• Anticipation of need for a major surgical procedure or radiation therapy (RT) during the study.
• Treatment with chemotherapy, radiotherapy, surgery, immunotherapy, biological therapy, or any other investigational anticancer agent within 4 weeks prior to start of study treatment.
• History of cardiac disease:
• Congestive heart failure defined as Class II to IV per New York Heart Association (NYHA) classification.
• Active coronary artery disease (CAD).
• Previously diagnosed bradycardia or other cardiac arrhythmia defined as Grade 2 or higher according to NCI CTCAE, version 4.0, or uncontrolled hypertension.
• Myocardial infarction that occurred within 6 months prior to start of study treatment (myocardial infarction that occurred greater than 6 months before the start of study treatment is permitted).
• Malabsorption syndrome, chronic diarrhea (lasting greater than 4 weeks), inflammatory bowel disease, or partial bowel obstruction.
• Known metastatic brain or meningeal tumors, unless the participant is greater than 6 months from definitive therapy, has a negative imaging study within 4 weeks of first dose of study treatment, and is clinically stable (no concomitant therapy, including supportive therapy with steroids or anticonvulsant medications) with respect to the tumor at the time of first dose of study treatment.
• Uncontrolled seizure disorder, spinal cord compression, or carcinomatous meningitis.
