Evaluation of Cetuximab (ERBITUX) and Concurrent Carboplatin, Paclitaxel & Radiotherapy in the Management of Patients With Advanced Locoregional Squamous Cell Carcinomas of the Head and Neck (GCC 0442)

Primary Objective- To evaluate whether the addition of Cetuximab (C225) in combination with chemotherapy and radiation can cause an enhanced anti-tumor effect resulting in improving local regional control of patients with locally advanced, unresectable squamous cell carcinoma of head and neck. (SCCHN).

OVERVIEW OF STUDY DESIGN Open label, non-randomized, single arm trial.

P = Paclitaxel will be administered on a weekly schedule at a dose of 40mg/m2 IV by 1-hour infusion prior to cetuximab dose. This will be administered for a total of 8 weeks (from weeks 2-9)

C225 = Cetuximab: 400 mg/m2 IV will be given as the initial OR loading dose in week 1 and then 250 mg/m2 IV weekly will be given for 8 weeks (weeks 2-9).

C = Carboplatin will be given at a dose of AUC=2/week - will be administered as a 30 minute infusion after cetuximab infusion (weeks 2-9)

RT = Radiation therapy will be delivered at 1.8 Gy fraction/day, 5 days a week for a total of 70.2 Gy. RT will be given from weeks 2-9.

Note: Sequence of administration will be paclitaxel followed by cetuximab followed by carboplatin followed by XRT.

Approximately 60 patients from MSGCC/BVAMC will participate in this study. Prior to entering the study the doctor will examine the patient and order blood tests ( which will be done by blood draw, approximately 2 tablespoons) and tests to measure the patients disease (scans). The patient will also be evaluated by a dietician who will follow the patient throughout the course of the therapy to help the patient meet his/her nutritional needs
