Erlotinib, Paclitaxel, and Carboplatin in Treating Patients With Stage III, Stage IV, or Recurrent Non-Small Cell Lung Cancer

OBJECTIVES:

• Compare the major objective response (complete and partial response) rates in patients with stage IIIB or IV or recurrent non-small cell lung cancer treated with high- versus low-dose erlotinib hydrochloride combined with paclitaxel and carboplatin.
• Compare the duration of response, time to progression, and survival of patients treated with these regimens.
• Characterize and compare the toxicities of these regimens.
• Determine the recommended phase III dose of erlotinib hydrochloride.

OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to gender. Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive oral high-dose erlotinib hydrochloride on days 1 and 2. Patients also receive paclitaxel IV over 3 hours followed by carboplatin IV over 30 minutes on day 3.
• Arm II: Patients receive oral low-dose erlotinib hydrochloride, paclitaxel, and carboplatin as in arm I.

In both arms, treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 58 patients will be accrued for this study.
