Brief Summary

This is a study for patients with head and neck cancer who will be receiving chemotherapy and radiation therapy for their disease. The purpose of this study is to see if the investigators can use genetic differences between patients to select the right drug to use with radiation therapy. This type of genetic testing is called pharmacogenetics.

Currently there are two drugs used to treat head and neck cancer that have provided a benefit when given with radiation compared to radiation alone in previous studies. These two drugs are cisplatin and cetuximab (Erbitux).

In this trial, the investigators will test whether genetic differences between patients can be used to pick which drug they should receive. A recent study that looked back to see how well patients with head and neck cancer responded to treatment with cisplatin showed that genetic differences in a few genes were associated with who did and who did not survive their cancer. The investigators are taking that finding and using it to test patients for these genetic differences to determine whether they should receive cisplatin or cetuximab. In other words, the investigators are trying to take what is essentially a flip of the coin choice between these two drugs, and instead use individual patient's genetic differences to make-and hopefully improve- this choice.

Detailed Description

Treatment-naive patients with locally advanced, non-metastatic (Stage III to IVB) squamous cell carcinoma of the head and neck who are candidates for concurrent chemoradiotherapy as primary therapy with curative intent will be enrolled. Patients will be genotyped for variations at four SNP loci in 3 genes involved in DNA nucleotide excision repair (ERCC1, ERCC2, and XRCC1). Patients with 3 to 8 variants will receive cisplatin, while patients with 2 or fewer variants will receive cetuximab.

Conditions

Head and Neck Cancer

Study Design

• Allocation Method: NON_RANDOMIZED
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Cetuximab

patients with 2 or fewer genetic variants will receive cetuximab

Group Type: EXPERIMENTAL

Cetuximab

Intervention Type: DRUG

Intensity modulated Radiation Therapy with concurrent chemotherapy. Cetuximab will be administered beginning at a dose of 400 mg/m2 the week before radiation commences, then at a dose of 250 mg/m2 weekly during weeks 1 to 7. Post treatment neck dissection will be performed if clinically indicated.

Cisplatin

Subjects with 3 to 8 genetic variants will receive cisplatin

Group Type: EXPERIMENTAL

Cisplatin

Intervention Type: DRUG

Intensity modulated radiation therapy with concurrent chemotherapy. Cisplatin will be administered at a dose of 100 mg/m2 during weeks 1, 4, and 7 of radiation therapy. Post treatment neck dissection will be performed if clinically indicated.

Interventions

Cisplatin

Intensity modulated radiation therapy with concurrent chemotherapy. Cisplatin will be administered at a dose of 100 mg/m2 during weeks 1, 4, and 7 of radiation therapy. Post treatment neck dissection will be performed if clinically indicated.

Intervention Type: DRUG

Cetuximab

Intensity modulated Radiation Therapy with concurrent chemotherapy. Cetuximab will be administered beginning at a dose of 400 mg/m2 the week before radiation commences, then at a dose of 250 mg/m2 weekly during weeks 1 to 7. Post treatment neck dissection will be performed if clinically indicated.

Intervention Type: DRUG

Other Intervention Names

cis-diamminedichloridoplatinum(II); CDDP; Erbitux
