Alternate Title

Gefitinib and Radiation Therapy With or Without Cisplatin in Treating Patients With Stage III or Stage IV Head and Neck Cancer

Basic Trial Information

Objectives

1. Determine the maximum tolerated dose of gefitinib in combination with radiotherapy with or without cisplatin in patients with previously untreated, locally advanced squamous cell carcinoma of the head and neck.
2. Determine the dose-dependent local and/or systemic toxic effects of these regimens in these patients.
3. Determine the feasibility and toxicity profile of protracted continuous daily dosing of gefitinib after completion of radiotherapy in these patients.
4. Determine the response rate, relapse-free survival rate, and overall survival rate in patients treated with these regimens.

Entry Criteria

• No uncontrolled concurrent medical or psychiatric illness or social situation that would preclude study participation

Expected Enrollment

A total of 30 patients will be accrued for this study.

Outcomes

Safety profile of gefitinib
Maximum tolerated dose as assessed by dose-limiting toxicities from 0-2 years
Dose-dependent local and/or systemic toxicity as assessed by CTC v 2.0 from 0-2 years
Feasibility and toxicity profile as assessed by CTC v 2.0 at 2 years post-radiotherapy

Response rates, relapse-free survival rates, and overall survival rates as measured by radiological assessments every 4 months for 2 years, at 2 years, and every 6 months for years 3-5
Biological effects as assessed by biological analyses after 1 week of treatment, weekly during treatment, and at 8 weeks post-radiotherapy

Outline

This is a multicenter, dose-escalation study of gefitinib.

All patients receive oral gefitinib once daily beginning at least 7 days before and continuing throughout radiotherapy or chemoradiotherapy in the absence of disease progression or unacceptable toxicity. Patients are entered into 1 of 5 levels.

• Level I: Patients undergo concurrent boost radiotherapy 5 days per week comprising once daily radiotherapy for 3.5 weeks followed by twice daily radiotherapy for 2.5 weeks.
• Level II: Patients receive escalated dose of gefitinib and undergo radiotherapy as in level I.
• Level III: Patients receive original dose of gefitinib, undergo standard fractionation radiotherapy comprising once daily radiotherapy 5 days per week for 7 weeks, and receive cisplatin IV over 30-60 minutes at the beginning of each week of radiotherapy.
• Level IV: Patients receive escalated dose of gefitinib as in level II and undergo radiotherapy and chemotherapy as in level III.
• Level V: Patients receive the maximum tolerated dose (MTD) of gefitinib, radiotherapy 5 days a week for 6 weeks, and chemotherapy as in level III.

Patients with clinical or radiologic evidence of residual disease are required to undergo neck dissection approximately 8 weeks after completion of radiotherapy or chemoradiotherapy.

Patients resume oral gefitinib daily beginning 8 weeks after the completion of radiotherapy or chemoradiotherapy (12 weeks for patients who undergo neck dissection) and continuing for 2 years in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients are enrolled sequentially beginning at level I until the MTD of gefitinib is determined. The MTD is the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity.

Twelve additional patients receive the MTD of gefitinib in combination with radiotherapy with or without cisplatin.

Patients are followed every 6 months for at least 5 years.
