Cetuximab in Combination With Paclitaxel Plus Cisplatin Versus Paclitaxel Plus Cisplatin Alone for the First-line Treatment of Metastatic Esophageal Squamous Cell Carcinoma

This is an open-label, randomized, controlled trial. At the end of a 28-day screening period, all eligible subjects will be randomly assigned into treatment Arm A or B in a 1:1 ratio. Subjects in Arm A will receive a maximum of 6 cycles of chemotherapy (cisplatin plus paclitaxel) and cetuximab weekly in the absence of progressive disease (PD), as assessed by the Investigator, and unacceptable toxicity. After 6 cycles of treatment, subjects who derive clinical benefit will continue treatment with cetuximab as monotherapy until either PD or unacceptable toxicity. Subjects in Arm B will receive the same chemotherapy regimen as Arm A alone for a maximum of 6 cycles in the absence of PD and unacceptable toxicity.
