PURPOSE: To evaluate the efficacy and safety of the antiepidermal growth factor receptor monoclonal antibody cetuximab in combination with platinum-based chemotherapy in patients with platinum-refractory recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN).
PATIENTS AND METHODS: Ninety-six eligible patients received cetuximab (initial dose of 400 mg/m2 followed by subsequent weekly doses of 250 mg/m2) followed by platinum chemotherapy at the same dose and schedule at which progressive disease was documented before entry onto the study.
RESULTS: The response rate, based on an independently read assessment, in the intent-to-treat population was 10%, with a disease control rate (complete response, partial response [PR], and stable disease) of 53%. The median time to progression and overall survival were 85 and 183 days, respectively; both were longest in patients achieving a PR (median, 203.5 and 294 days, respectively). Treatment was well tolerated. The most common cetuximab-related adverse events were skin reactions, particularly an acne-like rash.
CONCLUSION: The combination of cetuximab and platinum chemotherapy is an active and well-tolerated approach to the treatment of this poor-prognosis patient population with platinum-refractory recurrent or metastatic SCCHN for whom there are no recommended standard therapeutic options.
