Erlotinib in Treating Patients With Stage III or Stage IV Non-Small Cell Lung Cancer

A Randomised, Placebo-Controlled Trial of Erlotinib in Patients With Advanced NSCLC Unsuitable for Chemotherapy

RATIONALE: Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether erlotinib is more effective than a placebo in treating non-small cell lung cancer.

PURPOSE: This randomized phase III trial is studying erlotinib to see how well it works compared to a placebo in treating patients with stage III or stage IV non-small cell lung cancer.

OBJECTIVES:

Primary

• Compare survival of patients with stage IIIB or IV non-small cell lung cancer that is not suitable for first-line chemotherapy treated with erlotinib vs placebo.

Secondary

• Compare progression-free survival and response rate.
• Compare toxicity.
• Compare the quality of life.
• Compare cost-effectiveness.

OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive oral erlotinib once daily for up to 24 months.
• Arm II: Patients receive oral placebo once daily for up to 24 months. Quality of life is assessed periodically.

After completion of study treatment, patients are followed periodically for survival.

PROJECTED ACCRUAL: A total of 664 patients will be accrued for this study.

DISEASE CHARACTERISTICS:

• Histologically or cytologically confirmed non-small cell lung cancer

  • Advanced disease (stage IIIB or IV)
  • Diagnosis within 62 days prior to randomization

• Not suitable for first-line chemotherapy, as defined by the following criteria*:

  • ECOG performance status 2-3
  • ECOG performance status 0-1 AND creatinine clearance < 60 mL/min

• NOTE: *These criteria do not imply that all such patients are unsuitable for chemotherapy; patients are considered unsuitable on a case by case basis

• No symptomatic brain metastases

PATIENT CHARACTERISTICS:

• Estimated life expectancy of at least 8 weeks
• Able to take oral medication
• Not pregnant or nursing
• Fertile patients must use effective contraception
• No severe uncontrolled infection
• No unstable angina
• No myocardial infarction within the past month
• No uncontrolled inflammatory bowel disease (e.g., Crohn's disease or ulcerative colitis)
• No acute renal failure
• Bilirubin < 2 times upper limit of normal (ULN)
• Transaminases < 2 times ULN (5 times ULN if liver metastases are present)
• Creatinine < 5 times ULN
• No evidence of other significant laboratory finding or uncontrolled medical illness that would interfere with study treatment or results comparison or render the patient at high risk from treatment complications
• No other prior or current malignant disease likely to interfere with study treatment or comparisons

PRIOR CONCURRENT THERAPY:

• No prior chemotherapy

• No prior biological anticancer therapy (e.g., gefitinib, thalidomide, or cetuximab)

• No prior palliative radiotherapy

  • Prior palliative radiotherapy to bone metastases allowed within the past 2 weeks

• No concurrent cyclooxygenase-2 inhibitors
