Study of Anti-Epidermal Growth Factor Receptor (EGFr) Antibody, Cetuximab, in Combination With Gemcitabine/Carboplatin in Patients With Stage IV Lung Cancer

A loading dose of Cetuximab (400 mg/m2 IV over 120 minutes) will be administered 1 week prior to chemotherapy. Thereafter, Cetuximab will be infused weekly at maintenance doses of 250 mg/m2 (over 60 minutes). On the first day of each new cycle of therapy, Carboplatin will be infused with Gemcitabine (Days 1 and 8). Patients will be evaluated for a tumor response following every two cycles of therapy. In the absence of progressive disease, patients may continue to receive additional therapy.
