Participants receiving palliative radiation therapy to bony metastases prior to the first dose of study medication are eligible. The participant is receiving therapy with immunosuppressive agents.

The participant has uncontrolled hypertension defined as systolic blood pressure greater than or equal to 180 millimeters of mercury (mm Hg) or diastolic blood pressure greater than or equal to 130 mm Hg. The participant has a history of allergic reactions attributed to compounds of chemical or biologic composition similar to those of cetuximab or carboplatin. The participant has a medical or psychological condition that would not permit the participant to complete the study or sign informed consent. The participant has clinically relevant coronary artery disease or history of myocardial infarction in the last 12 months or high risk of uncontrolled arrhythmia or uncontrolled cardiac insufficiency.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Cetuximab and Carboplatin (D)<br>Group D: Cycle 1 (1 week, combination therapy): 400 milligrams per square meter (mg/m ²) cetuximab administered intravenously (I.V) on week 1,day 1. Carboplatin area under the curve (AUC=5) administered I.V on week 1,day 1. Optional 5- fluorouracil (FU) administered as a 96-hour continuous infusion (C.I.) of 1000 mg/ m ²/day administered starting on week 1, day 1. After 1 cycle, participants may then receive cetuximab as determined by clinical exam or radiological imaging studies until progression of disease, unacceptable toxicity, or another withdrawal criterion is met. After protocol amendment February 2014, any newly enrolled participants were placed into Group D only. | Drug: Cetuximab<br>* Administered Intravenously<br>Drug: Carboplatin<br>* Administered Intravenously<br>Drug: 5 - FU<br>* Administered Intravenously<br>|
