Trial Description

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Biological therapies such as gefitinib may interfere with the growth of the tumor cells and slow the growth of tumors. It is not yet known whether combination chemotherapy plus radiation therapy is more effective with or without gefitinib in treating non-small cell lung cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy plus radiation therapy with or without gefitinib in treating unresectable stage III non-small cell lung cancer.

Further Study Information

OBJECTIVES:

• Compare cisplatin, etoposide, radiotherapy, and docetaxel with or without gefitinib, in terms of improving overall survival and progression-free survival, in patients with unresectable stage III non-small cell lung cancer.

• Determine the toxicity profile of gefitinib in these patients.

OUTLINE: This is a randomized, double-blind, multicenter study. Patients are stratified according to performance status (0 vs 1), stage (stage IIIA vs IIIB), measurability of lesion (measurable vs nonmeasurable), and histologic subtype (squamous vs nonsquamous).

Patients receive induction therapy comprising cisplatin IV over 1 hour on days 1, 8, 29, and 36 and etoposide IV over 1 hour on days 1-5 and 29-33. Beginning within 24 hours after starting chemotherapy, patients receive concurrent induction radiotherapy 5 days a week for 5 weeks and then boost radiotherapy 5 days a week for 1.5 weeks.

Beginning approximately 4-8 weeks after completion of chemoradiotherapy, patients with stable or responding disease receive consolidation therapy comprising docetaxel IV over 1 hour on day 1. Treatment repeats every 21 days for 3 courses.

Patients with stable or responding disease are randomized to one of two treatment arms for maintenance therapy. Patients begin maintenance therapy approximately 4-7 weeks after completion of consolidation therapy.

• Arm I: Patients receive oral gefitinib daily.

• Arm II: Patients receive oral placebo daily. In both arms, maintenance therapy continues for a maximum of 5 years in the absence of disease progression or unacceptable toxicity.

Patients are followed every 6 months for 5 years and then annually for 5 years.

PROJECTED ACCRUAL: A total of 840 patients will be accrued for this study within 3.5 years.
