Randomized Amifostine For SCCHN

Amifostine is a drug that is used to treat moderate to severe xerostomia (dry mouth) for
those who receive radiation therapy for head and neck cancer. It was approved by the FDA for
use intravenously. This study plans to examine the effects of xerostomia when Amifostine is
used subcutaneously (by injection). Amifostine has been seen to be effective when used to
combat the effects of dry mouth, but also has some side effects which are listed later in
this consent form.

The purpose of this study is to examine the effectiveness of twice a day radiation therapy
given with chemotherapy consisting of carboplatin and paclitaxel (Taxo 1). This study will
examine the effectiveness of adding Amifostine in the hopes of reducing the side effects of
radiation.

Inclusion Criteria

Biopsy is preferred unless medically contraindicated.

of the nasal and paranasal cavities will also be included. Unknown primary SCC in the
neck will also be eligible.

- Stage 2, 3 or 4 disease without evidence of distant metastases verified by chest
X-Ray, abdominal ultrasound or CT (in case of liver function test abnormalities);
bone scan in case of local symptoms.

- At least one uni- or bidimensionally measurable lesion at the start of all therapy
(induction therapy ag well as chemoradiation).

- No previous head and neck radiotherapy and no previous curative surgery for SCCHN
(other than biopsy) are allowed at time of study entry.

- Age ≥ 18 years.

- WHO performance status of 0 or 1 (section 13, Appendix I)

- No active alcohol addiction (as assessed by medical caregiver).

- Life expectancy ≥ 12 weeks.

- Signed informed consent prior to beginning protocol specific procedures.

- Adequate bone marrow, hepatic and renal functions as evidenced by the following:

- Hematology:

- neutrophil count ≥ 2.0 x 10 9/1.

trial must be treated and followed at the participating centers

starting radiation therapy and that it is being used to treat head and neck cancers.

contraception.
